1.0 INTRODUCTION

This report presents the results of acute and chronic toxicity tests completed on a series of composite effluent samples collected from FPL Energy Seabrook Station, Seabrook, New Hampshire. Testing was based on programs and protocols developed by the US EPA (2002). A 48 hour static acute toxicity test was conducted using the mysid shrimp, Americamysis bahia, a 7 day modified acute and chronic toxicity test was conducted with the inland silverside, M. beryllina, and a 60 minute chronic fertilization assay was conducted with the purple sea urchin, A. punctulata. Testing was performed aftE'viroSystems, Incorporated (ESI), Hampton, New Hampshire in accordance with the provisions of the NELAC Standards (2000).Acute toxicity tests involve preparing a series of concentrations by diluting effluent with control water.Groups of test organisms are exposed to each effluent concentration and a control for a specified period. In acute tests, mortality data for each concentration are used to calculate (by"regression) the median lethal concentration, or LC-50, defined as the effluent concentration-which kills half of the test organisms. Samples with high LC-50 values are less likely to cause significant environmental impacts. The no-effect concentration is also determined toprovide information about the level of effluent Which would have minimal acute effects in the environment. This Acute No Observed Effect Concentration (A-NOEC) is defined as the highest tested effluent.concentration which causes no significant mortality. Chronic tests evaluate toxicity based on sublethal effects. Fertilization of Arbacia punctulata eggs or growth (weight) of Menidia beryllina are measured to determine effluent concentrations that have asignificant impact o6 the organisms. Using Analysis of Variance techniques to evaluate the data, it is possible to determine the lowest concentration that had an effect (C-LOEC) and the highest concentration where no effect was observed(C-NOEC). A. punctulata fertilization data are also evaluated to determine the effluent concentration where a reduction in fertilization rates occurs. This is known as the Inhibition Concentration (IC).2.0 MATERIALS AND METHODS.2.1 General Methods Toxicological and analytical protocols used in this program follow procedures primarily designed by the EPA to provide standard approaches for the evaluation of toxicological effects of discharges on aquatic organisms, and for the analysis of water samples.2.2 Test Species When necessary, A. bahia and M. beryllina were acclimated to approximate test conditions prior to use in the assay and then transferred to te~t chambers using a large bore glass pipet, minimizing the amount of water added to test solutions. Male and female A. punctulata are maintained in separate chambers as recommended by protocol (EPA 2002).2.3 Effluent, Receiving Water and Laboratory Water Effluent and receiving water collection information is provided in Table 1. Samples were stored at4°C and warmed to 25+/-1 °C prior to preparing test solutions. When necessary, effluent used in the A. bahia and M. beryllina assays was salinity adjusted to 25+/-2 ppt and the effluent used in the A. punctulata assay was salinity adjusted to 30+/-2 ppt using artificial sea salts according to protocol (EPA 2002). Effluent and receiving water samples that were received at or above a salinity of 25+/-2 ppt did not require salinity adjustment (EPA 2002). Laboratory water was collected from the Hampton/Seabrook Estuary. This water is classified as SA-1 FPL Energy Seabrook Station Effluent Evaluation, August 2009.Study Number 18858. Page 3 of 12 and has been used to culture marine test organisms since 1981.Total residual chlorine (TRC) was rfiieasured by amperometric titration (MDL 0.02 mgIL) in effluent and diluent samples. Samples containing 0.02 mg/L TRC were treated with sodium thiosulfate (EPA 2002).2.4 Bioassays Test concentrations for the assays were 100%, 50%, 25%, 12.5%, and 6.25% effluent.2.4.1 Americamysis bahia Acute Exposure Bioassay The 48 hour static acute assay was conducted at 25+/-1 °C with a photoperiod of 16:8 hours light:dark. Test chambers were 250 mL glass beakers with 200 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Survival and dissolved oxygen were recorded daily in all replicates. Temperature, pH, and salinity were measured in one replicate of each test treatment daily.2.4.2 Menidia beryllina Chronic Exposure Bioassay The 7 day static renewal chronic exposure assay was conducted at 25+/-1 °c with a photoperiod of 16:8 hours light:dark. Fish were maintained in 600 mL beakers containing 500 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Prior to daily renewals, survival and dissolved oxygen in all replicates were recorded and pH, salinity and temperature were measured in one replicate of each test treatment. Dissolved oxygen, salinity, pH, and temperature were measured in one replicate of each new test treatment. Survival data was analyzed to assess acute toxicity after the initial 48 hours of exposure.During the test, fish were fed 24 hour old Artemia nauplii twice a day. On Day 7 of the assay surviving fish were removed from test solutions, rinsed to remove any surface detritus and salts, and tranquilized using Finquel brand tricaine rnethanesulfonate. Fish were placed on tared containers and dried for 24 hours at 104'C to obtain dry weight to the nearest 0.01 mg. To obtain final dry weight/fish used for statistical comparisons, the net dry weight was divided by the number of organisms introduced at the initiation of the assay.2.4.3 Arbacia punctulata Chronic Fertilization Bioassay Test chambers were 20 mL glass vials with 5 mL of test solution in each of 4 replicates. Gametes were obtained by potassium chloride injection to induce spawning. Sperm were collected dry, diluted (see data appendix for final counts) and exposed to effluent solutions for 60 minutes. Eggs were introduced to sperm/effluent solutions and exposed for20 min utes priorto the addition of preservative. Aliquots of preserved solution were counted to determine fertilized and unfertilized eggs.2.5 Data Analysis Statistical analysis of acute and chronic exposure data was completed using CETIS, Comprehensive Environmental Toxicity Testing System, software. The program computes acute and chronic exposure endpoints based on EPA decision tree guidelines specified in individual test methods. For chronic exposure endpoints statistical significance was accepted at -<0.05.2.6 Quality Control As part of the laboratory quality control program, standard reference toxicant assays are conducted on a regular basis for each test species. These results, Table 2, provide relative health and response data while allowing for comparison with historic data sets. .3.0 RESULTS AND DISCUSSION LC-50 and A-NOEC values from the A. bahia acute exposure assays are presented in Table 3. Data from the A. punctulata fertilization assay are summarized in Table 4. Results of the chronic exposure assay FPL Energy Seabrook Station Effluent Evaluation, August 2009.Study Number 18858. Page 4 of 12 conducted using M. beryllitta are provided in Table 5. A summary of water quality data collected during the assays, is presented in Table 6. US EPA Attachment F toxicity test summary forms are included after the tables. Support data, including copies of laboratory bench sheets, can be found in Appendix A.3.1 Americamysis bahia Acute Exposure Bioassay Minimum test acceptability criteria require 290% survival in the control concentrations. Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 3 for test acceptability.

3.2 Arbacia

punctulata Chronic Fertilization Bioassay Protocol specifies a 70% to 90% fertilization rate-and the MSDp for fertilization to be <25% for Arbacia punculata (EPA 2002). Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse im pact on the outcome of the assay. See the Executive Summary and Table 4 for test acceptability.

3.3 Menidia

beryllina Chronic Exposure Bioassay Minimum test acceptability criteria require 80% control survival, a mean dry weight of 0.500 mg/fish based on Day 7 survival, and the MSDp for biomass to be <28% for. Menidia beryllina (EPA 2002).Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 5 for test acceptability.

Box 8127 Boston, MA 02114 Seabrook Station October 2009 Discharge Monitoring Reports NextEra Energy Seabrook, LLC, the operator of Seabrook Station, has enclosed Discharge Monitoring Reports (DMR) for the month of October 2009. The enclosed DMRs (Enclosure 1)are submitted, pursuant to Part I.B of the referenced NPDES permit. Northeast Laboratory Services of Winslow, ME performed Metal Cleaning Waste analyses for Outfall 26A. Copies of the Outfall 026A analytical reports are enclosed. Seabrook Station Chemistry Department personnel performed the remaining required analyses.This report is submitted for all discharge numbers. Outfalls 003A and 025B had no flow during the month of October, as indicated by the presence of a no discharge code, "C", in the "No Discharge" block.The following methods were used to perform analyses, applying the listed Minimum Detectable Levels (MDLs) where applicable: Analysis Method MDL Total Residual Oxidants Std. Methods (1 8 th) 4500-Cr- D 0.05 mg/L pH Std. Methods (1 8 1h) 4500-H+ B --Oil & Grease EPA Method 1664A 5.0.mg/L Nonfilterable Residue (TSS) Std. Methods (1 8 1h) 2540 D 0.3 mg/L Outfall 001A Discharges were made from the Circulating Water System (Outfall 00i) for 31 days in October.No visible oil sheen, foam or.floating solids were noted during the month. The DMR for Outfall 001 indicates a sampling frequency of one TRO analysis per day for the month of October. One additional sample was performed on October 01. All sample results have been included in the monthly average. The DMR also indicates a maximum pH of 8.2 s.u. This was determined not to be an exceedence as the intake water pH was eqpcltlo the dischaXge water pH.NextEra Energy Seabrook, LLC, P.O. Box 300, Lafayette Road, Seabrook, NH 03874 Environmental Protection Agency SBK-L-09236/ Page 2 Outfalls 022A, 023A, 024A Discharges were made from the oil/water separator vaults (Outfalls 022, 023, and .024)throughout the month of October. No exceedences occurred.Outfall 025A One continuous discharge occurred during the month of October. The discharge began. on September 30 and was terminated in the early moming-of October 1. Samples for this discharge were collected on September 30 and reported in that month; the daily flow for October 1 is therefore reported without any sample analysis as indicated by the NODI code. No exceedences occurred.Outfall 025C One batch discharge occurred during the month of October. No exceedences occurred.Outfall 025D Nine batch discharges occurred during the month of October. No exceedences occurred.Outfall 026A Three batch discharges occurred during the month of October. No exceedences occurred.NextEra Energy Seabrook requested and received a'clarification letter from the EPA (ref: EPA letter dated August 6, 2009 from David Webster to Michael O'Keefe) regarding the manner in which compliance with certain effluent limitations for Outfall 026 would be ascertained. The clarification pertained to the daily maximum concentration limit for iron and copper and the pH limit for the processed wastewater. The EPA clarification letter authorized the discharge of iron and copper from this outfall pursuant to a daily mass limit of 3.75 lbs for each metal. The spreadsheet provided in the enclosure to this letter includes calculations confirming that the 3.75 lb. daily mass limit was complied with for each metal. The Outfall 026 discharge concentration limit for the metals, 1 mg/L, was also complied with although our initial estimates for the iron and copper concentrations indicated that the permit limit may be exceed. The Reverse Osmosis treatment process yielded greater metal removal than estimated and compliance was achieved. The additional information requested by EPA clarification letter is provided in the .enclosed spreadsheet. The dilution water flow rate assumption is 387,000 GPM and is-determined by pump curves. Environmental Protection Agency SBK-L-09236/ Page 3 Additionally the EPA clarification letter indicated that-the chemical cleaning wastewater may be discharged at a pH greater than allowed for the internal Outfall 026 (6.0 -9.0 s.u.) and so long as the pH at outfall 001 is maintained between the water quality based range of 6.5 -8.0 s.u. the NPDES Permit pH limits would be complied with. Based on the EPA clarification the DMR for Outfall 026 specifies a maximum pH of 10.5 s.u. with no permit exceedence. The measured pH at Outfall 001 during the three discharges is provided on the enclosed spreadsheet. Outfall 027A Seven discharges were made from the Cooling Tower to support maintenance activities during the month of October. No exceedences occurred..If you have questions on this matter, please contact me at (60-3) 773-7745.Sincerely, NextEra Energy Seabrook, LLC Michael D,6'I('eefe , V Licensing Manager cc: New Hampshire Department of Environmental Services (NIDES)Water Division Wastewater Engineering Bureau 29 Hazen Drive, P.O.

The enclosed DMRs are submitted pursuant to Part 1.8 of the referenced NPDES permit. Northeast Laboratory Services of Winslow, ME performed Metal Cleaning Waste analyses for Outfall 26A. Copies of the Outfall 026A analytical reports are enclosed. Seabrook Station Chemistry Department personnel performed the remaining required analyses.This report is submitted for all discharge numbers. Outfalls 003A and 025B had no flow during the month of November, as indicated by the presence of a no discharge code, "C", in the "No Discharge" block.The following methods were used to perform analyses, applying the listed Minimum Detectable Levels (MDLs) where applicable: Analysis Method MDL Total Residual Oxidants Std. Methods ( 8th) 4500-C1- D 0.05 mg/L pH Std. Methods (18') 4500-H+ B --Oil & Grease EPA Method 1664A 5.0 mg/L Nonfilterable Residue (TSS) Std. Methods (1 8 th) 2540 D 0.3 mg/L Outfall 001A Discharges were made from the Circulating Water System (Outfall 001) for 30 days in November. No visible oil sheen, foam or floating. solids were noted during the month.NextEra Energy Seabrook, LLC, P.O. Box 300, Lafayette Road, Seabrook, NH 03874 Environmental Protection Agency SBK-L-09255/ Page 2 One continuous discharge and six batch discharges were made during the month of November from the Condensate Polisher System. As described in the NPDES Permit application discharges are monitored to ensure compliance with Outfall 001 requirements. Seabrook Station's thirteenth refueling outage began Oct. 01, 2009 and concluded Nov. 12, 2009. The refueling outage required many of the plant systems to be drained to the Circulating Water System (Outfall 001). Plant system drainage was sampled and accounted for .in the appropriate outfall.Outfalls"022, 023, 024 Discharges were made from the oil/water separator vaults (Outfalls 022, 023, and 024)throughout the month of November. No exceedences occurred.Outfall 025A One continuous discharge occurred during the month of November. No exceedences occurred.Outfall 025C Four batch discharges occurred during the month of November. No exceedences occurred.Outfall 025D Five batch discharges occurred during the month of November. No exceedences occurred.Outfall 026A Two batch discharges occurred during the month of November. No exceedences occurred.NextEra Energy Seabrook requested and received a clarification letter from the EPA (ref: EPA letter dated August 6, 2009 from David Webster to Michael O'Keefe) regarding the manner in which" compliance with certain effluent limitations for Outfall 026 would be ascertained. The clarification pertained to the daily maximum concentration limit for iron and copper and the pH limit for the processed wastewater. The EPA clarification letter authorized the discharge of iron and copper from this outfall pursuant to a daily mass limit of 3.75 lbs for each metal. The spreadsheet. provided in the enclosure to this letter, includes calculations confirming that the 3.75 lb. daily mass limit was complied with for each metal. The Outfall 026 discharge concentration limit for the metals, 1 mg/L, was also complied with although our initial estimates for the iron and copper concentrations indicated that the permit limit may be exceed. The Reverse Osmosis treatment process yielded greater metal removal than estimated and compliance was achieved. The additional information requested by EPA clarification letter is provided in the enclosed spreadsheet. The dilution water flow rate assumption is 387,000 GPM and is determined by pump curves. Environmental Protection Agency SBK-L-09255/ Page 3 Additionally the EPA clarification letter indicated that the chemical cleaning wastewater may be discharged at a pH greater than allowed for the internal Outfall 026 (6.0 -9.0 s.u.) anJ so long as the pH at outfall 001 is maintained.between the water quality based range of 6.5 -8.,0 s.u. the NPDES Permit pH limits would be complied with. Based on the EPA clarification the DMR for Outfall 026 specifies a maximum pH of 10.9 s.u. with no permit exceedence. The measured pH at Outfall 001 during the two discharges is provided on the enclosed spreadsheet. Outfall 027A Seven discharges were made from the Cooling Tower to support maintenance activities during the month of November. No exceedences occurred.If you have questions on this matter, please contact me at (603) 773-7745.Sincerely, NextEra Energy Seabrook, LLC Michael O'Keefe Licensing Manager cc: New Hampshire Department of Environmental Services (NHDES)Water Division Wastewater Engineering Bureau 29 Hazen Drive, P.O.

SUMMARY

The following summarizes the results of acute and chronic exposure bioassays performed during December 2009 to support the NPDES biomonitoring requirements of FPL Energy Seabrook Station, Seabrook, New Hampshire. Acute and chronic definitive assays were completed using the marine species, Americamysis bahia, Menidia beryllina, and Arbacia punctulata. A. bahia were <5 days old at the start of the test. M. bery/lina were 13 days old at the start of the test.A. punctulata were from cultures maintained by ESI. Original stock was obtained from commercial supply.Dilution water was receiving water collected off shore by Normandeau Associates, Bedford, New Hampshire. Samples were received under chain of custody in good order. All sample receipt, test conditions and control endpoints were within protocol specifications except where otherwise noted. The results presented in this report relate only to the samples described on the chain(s) of custody and sample receipt log(s).Results from the chronic and modified acute exposure assays and their relationship to permit limits are summarized in the following matrix.Acute Exposure Toxicity Evaluation Permit Limit (LC-50)Effluent Meets Permit Limit Assay Meets Protocol Requirements Species Exposure " LC-50 A-NOEC Americamysis bahia 48 Hours >100% 100% Report NA Yes Menidia beryllina 48 Hours >100% 100% Report NA Yes Chronic Exposure Toxicity Evaluation Effluent Assay Meets Permit Limit Meets Protocol Species Exposure C-NOEC LOEC (C-NOEC) Permit Limit Requirements Menidia beryllina Arbacia punctulata 7 Days 100% >100% Report NA NA Yes*Yes 60 Minutes 100%** >100%Report COMMENTS: The M. beryllina assay did not meet the suggested statistical variability limit (MSDp) of 28%, although this limit is not a requirement at this time.** The statistical analysis for A. punctulata fertilization determined the 50% test concentration was significantly less than the receiving water diluent control, however according to USEPA Region I policy it is not considered to be significantly less if fertilization is >70%. In addition, review of the urchin fertilization data documented a non-standard dose response curve and computation of the IC-1 0 resulted in a value of >100%. Based on this finding, the C-NOEC value most representative of the effluent is 100%.Page 2 of 12 TOXICOLOGICAL EVALUATION OF TREATED INDUSTRIAL EFFLUENT BIOMONITORING SUPPORT FOR A NPDES PERMIT: December 2009 FPL Energy Seabrook Station Seabrook, New Hampshire NPDES Permit Number NH0020338

1.0 INTRODUCTION

This report presents the results of acute and chronic toxicity tests completed on a series of composite effluent samples collected from FPL Energy Seabrook Station, Seabrook, New Hampshire. Testing was based on programs and protocols developed by the US EPA (2002). A 48 hour static acute toxicity test was conducted using the mysid shrimp, Americamysis bahia, a 7 day modified acute and chronic toxicity test was conducted with the inland silverside, M. bery/lina, and a 60 minute chronic fertilization assay was conducted with the purple sea urchin, A. punctulata. Testing was performed at EnviroSystems, Incorporated (ESI), Hampton, New Hampshire in accordance with the provisions of the NELAC Standards (2000).Acute toxicity tests involve preparing a series of concentrations by diluting effluent with control water.Groups of test organisms are exposed to each effluent concentration and a control for a specified period. In acute tests, mortality data for each concentration are used to calculate (by regression) the median lethal concentration, or LC-50, defined as the effluent concentration which kills half of the test organisms. Samples with high LC-50 values are less likely to cause significant environmental impacts. The no-effect concentration is also determined to provide information about the level of effluent which would have minimal acute effects in the environment. This Acute No Observed Effect Concentration (A-NOEC) is defined as the highest tested effluent concentration which causes no significant mortality. Chronic tests evaluate toxicity based on sublethal effects.' Fertilization of Arbacia punctulata eggs or growth (weight) of Menidia bery//ina are measured to determine effluent concentrations that have a significant impact on the organisms. Using Analysis of Variance techniques to evaluate the data, it is possible to determine the lowest concentration that had an, effect (C-LOEC) and the highest concentration where no effectwas observed (C-NOEC). A. punctulata fertilization data are also evaluated to determine the effluent concentration where a reduction in fertilization rates occurs. This is known as the Inhibition Concentration (IC).2.0 MATERIALS AND METHODS 2.1 General Methods Toxicological and analytical protocols used in this program follow procedures primarily designed by the EPA to provide standard approaches for the evaluation of toxicological effects of discharges on aquatic organisms, and for the analysis of water samples.2.2 Test Species When necessary, A. bahia and M. beryllina were acclimated to approximate test conditions prior to use in the assay and then transferred to test chambers using a large bore glass pipet, minimizing theamount of water added to test solutions. Male and female A. punctulata are maintained in separate chambers as recommended by protocol (EPA 2002).2.3 Effluent, Receiving Water and Laboratory Water Effluent and receiving water collection informatiQn is provided in Table 1. Samples were stored at40C and warmed to 25+/-1 °C prior to preparing test solutions. When necessary, effluent used in the A. bahia and M. beryllina assays was salinity adjusted to 25+/-2 ppt and the effluent used in the.A. punctulata assay was salinity adjusted to 30+/-2 ppt using artificial sea salts according to protocol (EPA 2002). Effluent and receiving water samples that were received at or above a salinity of 25+/-2 ppt did not require salinity adjustment (EPA 2002). Laboratory water was collected from the Hampton/Seabrook Estuary. This water is classified as SA-1 FPL Energy Seabrook Station Effluent Evaluation, December 2009.Study Number 19224. Page 3 of 12 and has been used to culture marine test organisms since 1981.Total residual chlorine (TRC) was measured by amperometric titration (MDL 0.02 mg/L) in effluent and diluent samples. Samples containing _0.02 mg/L TRC were treated with sodium thiosulfate (EPA 2002).2.4 Bioassays Test concentrations for the assays were 100%, 50%, 25%, 12.5%, and 6.25% effluent.2.4.1 Americamysis bahia Acute Exposure. Bioassay The 48 hour static acute assay was conducted at 25+/-1 °C with a photoperiod of 16:8 hours light:dark. Test chambers were 250 mL glass beakers with 200 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Survival and dissolved oxygen were recorded daily in all replicates. Temperature, pH, and salinity were measured in one replicate of each test treatment daily.2.4.2 Menidia beryllina Chronic Exposure Bioassay The 7 day static renewal chronic exposure assay was conducted at 25+/-1 'C with a photoperiod of 16:8 hours light:dark. Fish were maintained in 600 mL beakers containing 500 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Prior to daily renewals, survival and dissolved oxygen in all replicates were recorded and pH, salinity and temperature were measured in one replicate of each test treatment, Dissolved oxygen, salinity, pH, and temperature were measured in one replicate of each new test treatment. Survival data was analyzed to assess acute toxicity after the initial 48 hours of exposure.During the test, fish were fed 24 hour old Artemia nauplii twice a day. On Day 7 of the assay surviving fish were removed from test solutions, rinsed to remove any surface detritus and salts, and tranquilized using Finquel brand tricaine methanesulfonate. Fish were placed on tared containers and dried for 24 hours at 1040C to obtain dry weight to the nearest 0.01 mg. To obtain final dry weight/fish used for statistical comparisons, the net dry weight was divided by the number of organisms introduced at the initiation of the assay.2.4.3 Arbacia punctulata Chronic Fertilization Bioassay Test chambers were 20 mL glass vials with 5 mL of test solution in each of 4 replicates. Gametes were obtained by potassium chloride injection to induce spawning. Sperm were collected dry, diluted (see data appendix for final counts) and exposed to effluent solutions for 60 minutes. Eggs were introduced to sperm/effluent solutions and exposed for 20 minutes prior to the addition of preservative. Aliquots of preserved solution were counted to determine fertilized and unfertilized eggs.2.5 Data Analysis When necessary, statistical analysis of acute and chronic exposure data was completed using CETIS, Comprehensive Environmental Toxicity Testing System, software. The program computes acute and chronic exposure endpoints based on EPA decision tree guidelines specified in individual test methods. If survival in the highest test concentration is >50%, the LC-50 is obtained by direct observation of the raw data. For chronic exposure endpoints statistical significance was accepted at <0.05.2.6 Quality Control As part of the laboratory quality control program, standard reference toxicant assays are conducted on a regular basis for each test species. These results, Table 2, provide relative health and response data while allowing for comparison with historic data sets.3.0 RESULTS AND DISCUSSION LC-50 and A-NOEC values from theA. bahia acute exposure assays are presented in Table 3. Data FPL Energy Seabrook Station Effluent Evaluation, December 2009.Study Number 19224. Page 4 of 12 from the A. punctulata fertilization assay are summarized in Table 4. Results of the chronic exposure assay completed using M. beryllina are provided in Table 5. A summary of water quality data collected during the assays is presented in Table 6. US EPA Attachment F toxicity test summary forms are included after the tables. Support data, including copies of laboratory bench sheets, can be found in Appendix A.3.1 Americamysis bahia Acute Exposure Bioassay Minimum test acceptability criteria require 90% survival in the control concentrations. Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on-the outcome of the assay. See the Executive Summary and Table 3 for test acceptability.

3.2 Arbacia

punctulata Chronic Fertilization Bioassay Protocol specifies a 70% to 90% fertilization rate and theMSDp for fertilization to be <25% for Arbacia punculata (EPA 2002). Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 4 for test acceptability.

3.3 Menidia

beryllina Chronic Exposure Bioassay Minimum test acceptability criteria require 80% control survival, a mean dry weight of 0.500 mg/fish based on Day 7 survival, and the MSDp for biomass to be <28% for Menidia beryina (EPA 2002).Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 5 for test acceptability.

1.0 INTRODUCTION

This report presents the results of acute and chronic toxicity tests completed on a series of composite effluent samples collected from FPL Energy Seabrook Station, Seabrook, New Hampshire. Testing was based on programs and protocols developed by the US EPA (2002). A 48 hour static acute toxicity test was conducted using the mysid shrimp, Americamysis bahia, a 7 day modified acute and chronic toxicity test was conducted with the inland silverside, M, beryllina, and a 60 minute chronic fertilization assay was conducted with the purple sea urchin, A. punctulata. Testing was performed at EnviroSystems, Incorporated (ESI), Hampton, New Hampshire in accordance with the provisions of the NELAC Standards (2000).Acute toxicity tests involve preparing a series of concentrations by diluting effluent with control water.Groups of test organisms are exposed to each effluent concentration and a control for a specified period. In acute tests, mortality data for each concentration are used to calculate (by regression) the median lethal concentration, or LC-50, defined as the effluent concentration which kills half of the test organisms. Samples with high LC-50 values are less likely to cause significant environmental impacts. The no-effect concentration is also determined to provide information about the levelof effluent which would have minimal acute effects in the environment. This Acute No Observed Effect Concentration (A-NOEC) is defined as the highest tested effluent concentration which causes no significant mortality. Chronic tests evaluate toxicity based on sublethal effects. Fertilization of Arbacia punctulata eggs or growth (weight) of Menidia beryllina are measured to determine effluent concentrations that have a significant impact on the organisms. Using Analysis of Variance techniques to evaluate the data, it is possible to determine the lowest concentration that had an effect (C-LOEC) and the highest concentration where no effect was observed (C-NOEC). A. punctulata fertilization data are also evaluated to determine the effluent concentration where a reduction in fertilization rates occurs. This is known as the Inhibition Concentration.(IC).

2.0. MATERIALS

AND METHODS 2.1 General Methods Toxicological and analytical protocols used in this program follow procedures primarily designed by the EPA to provide standard approaches for the evaluation of toxicological effects of discharges on aquatic organisms, and for the analysis of water samples.2.2 Test Species When necessary, A. bahia and M. beryllina were acclimated to approximate test conditions prior to use in the assay and then transferred to test chambers using a large bore glass pipet, minimizing the amount of water added to test solutions. Male and female A. punctulata are maintained in separate chambers as recommended by protocol (EPA 2002).2.3 Effluent, Receiving Water and Laboratory Water Effluent and receiving water collection information is provided in Table 1. Samples were stored at 4°C and warmed to 25+/-1 °C prior to preparing test solutions. When necessary, effluent used in the A. bahia and M. beryllina assays was salinity adjusted to 25+/-2 ppt and the effluent used in theA. punctulata assay was salinity adjusted to 30+/-2 ppt using artificial sea salts according to protocol (EPA 2002). Effluent and receiving water samples that were received at or above a salinity of 25+/-2 ppt did not require salinity adjustment (EPA 2002). Laboratory water was collected from the Hampton/Seabrook Estuary. This water is classified as SA-1 FPL Energy Seabrook.Station Effluent Evaluation, March 2010.Study Number 19504. Page 3 of 12 and has been used to culture marine test organisms since 1981: Total residual chlorine (TRC) was measured by amperometric titration (MDL 0.02 mg/L) in effluent and diluent samples. Samples containing 0.02 mg/L TRC were treated with sodium thiosulfate (EPA 2002).2.4 Bioassays Test concentrations for the assays were 100%, 50%, 25%, 12.5%, and 6.25% effluent.2.4.1 Americamysis bahia Acute Exposure Bioassay The 48 hour static acute assay was conducted at 25+/-1 'C with a photoperiod of 16:8 hours light:dark. Test chambers were 250 mL glass beakers with 200 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Survival and dissolved oxygen were recorded daily in all replicates. Temperature, pH, and salinity were measured in one replicate of each test treatment daily.2.4.2 Menidia beryllina Chronic Exposure Bioassay The 7 day static renewal chronic exposure assay was conducted at 25+/-1 °C with a photoperiod of 16:8 hours light:dark. Fish were maintained in 600 mL beakers containing 500 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Prior to daily renewals, survival and dissolved oxygen in all replicates were recorded and pH, salinity and temperature were measured in one replicate of each test treatment. Dissolved oxygen, salinity, pH, and temperature were measured in one replicate of each new test treatment. Survival data was analyzed to assess acute toxicity after the initial 48 hours of exposure.During the test, fish were fed 24 hour old Artemia nauplii twice a day. On Day 7 of the assay surviving fish were removed from test solutions, rinsed to remove any surface detritus and salts, and tranquilized using Finquel brand tricaine methanesulfonate. Fish were placed on tared containers and dried for 24 hours at 104'C to obtain dry weight to the nearest 0.01 mg. To obtain final dry weight/fish used for statistical comparisons, the net dry weightwas divided by the number of organisms introduced at the initiation of the assay.2.4.3 Arbacia punctulata Chronic Fertilization Bioassay Test chambers were 20 mL glass vials with 5 mL of test solution in each of 4 replicates. Gametes were obtained by potassium chloride injection to induce spawning. Sperm were collected dry, diluted (see data appendix for final counts) and exposed to effluent solutions for 60 minutes. Eggs were introduced to sperm/effluent solutions and exposed for 20 minutes prior to the addition of preservative. Aliquots of preserved solution were counted to determine fertilized and unfertilized eggs.2.5' Data Analysis When necessary, statistical analysis of acute and chronic exposure data was completed using CETIS, Comprehensive Environmental Toxicity Testing System, software. The program computes acute and chronic exposure endpoints based on EPA decision tree guidelines specified in individual test methods. If survival in the highest test concentration is >50%, the LC-50 is obtained by direct observation of the raw data. For chronic exposure endpoints statistical significance was accepted at <0.05.2.6 Quality Control As part of the laboratory quality control program, standard reference toxicant assays are completed on a regular basis for each test species. These results, Table 2, provide relative health and response data while allowing for comparison with historic data sets.3.0 RESULTS AND DISCUSSION LC-50 and A-NOEC values from the A. bahia acute exposure assays are presented in Table 3. Data FPL Energy Seabrook Station Effluent Evaluation, March 2010.Study Number 19504. Page 4 of 12 from the A. punctulata fertilization assay are summarized in Table 4. Results of the chronic exposure assay completed using M. beryllina are provided in Table 5. A summary of water quality data collected during the assays is presented in Table 6. US EPA Attachment F toxicity test summary forms are included after the tables. Support data, including copies of laboratory bench sheets, can be found in Appendix A.3.1 Americamysis bahia Acute Exposure Bioassay Minimum test acceptability criteria require ;90% survival in the control concentrations. Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 3 for test acceptability.

3.2 Arbacia

punctulata Chronic Fertilization Bioassay Protocol specifies a 70% to 90% fertilization rate and the MSDp for fertilization to be <25% for Arbacia punculata (EPA 2002). Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executiye Summary and Table 4 for test acceptability.

3.3 Menidia

beryllina Chronic Exposure Bioassay Minimum test acceptability criteria require 80% control survival, a mean dry weight of 0.500 mg/fish based on Day 7 survival, and the MSDp for biomass to be <28% for Menidia beryllina (EPA 2002).Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 5 for test acceptability.

The enclosed DMRs are submitted pursuant to Part I.B of the referenced NPDES permit. Seabrook Station Chemistry Department personnel performed the required. analyses.This report is submitted for all discharge numbers. Outfalls 003A and 026A had no flow during the month of May, as indicated by the presence of a no discharge code, "C", in the "No Discharge" block.The following methods were used to perform analyses, applying the listed Minimum Detectable Levels (MDLs) where applicable: Analysis Method MDL Total Residual Oxidants Std. Methods (1 8 th) 4500-C1- D 0.05 mg/L pH Std. Methods (18t") 4500-H÷ B --Oil & Grease EPA Method 1664A 5.0 mg/L Nonfilterable Residue (TSS) Std. Methods (1 8 th) 2540.D 0.3 mg/L Outfall 001A Discharges were made from the Circulating Water System (Outfall 001) for 31 days in May. No visible oil sheen, foam or -floating solids were noted during the month.During the seven day period of May 4 through May 10 one of the three ocean cooling water pumps was removed from service for scheduled maintenance. During this period with- two pumps in operation, the elevated temperature difference between the Intake and Discharge Transition Structures which is authorized by the permit for up to fifteen days per year was complied with.NextEra Energy Seabrook, LLC, P.O. Box 300, Lafayette Road, Seabrook, NH 03874 Environmental Protection Agency SBK-L-10110/Page 2 The daily maximum pH is reported as 8.3. The initial pH sample obtained from the Discharge Transition Structure on May 10 at 0905 AM yielded the 8.3 value. Subsequently as allowed by the permit a pH sample was obtained from the Intake Transition Structure to determine the naturally occurring pH at 0955 AM. The Intake transition Structure sample yielded a value of 8.2. A second set of pH samples were collected from both the Intake and Discharge Transition Structures at 1200 and the pH of both samples was reported as 8.0. It appears that a pH transient occurred in the offshore waters and that the second set of pH measurements were more indicative of pH values normally recorded. It was concluded that the Discharge Transition Structure pH value of 8.3 was equivalent to the naturally occurring intake water and that no exceedence occurred.No batch discharges were made during the month of May from the Condensate Polisher System.As described in the NPDES Permit application discharges are monitored to ensure compliance with Outfall 001 requirements. Outfall 001B The second quarter Whole Effluent Toxicity (WET) tests were performed in May 2010. No toxicity was observed in the effluent bioassays. The complete WET test report prepared by EnviroSystems, Inc. is provided in Enclosure 2.Sampling for the second quarter WET testing was performed under the following discharge scenarios: o Day 1 (May 10 -May 11, 2010) included discharges from Outfalls 025A & 025B, o Day 2 (May 12 -May 13, 2010) included a discharge from Outfall 025C,* Day 3 (May 14 -May 15, 2010) included a discharge from Outfall 025D.Outfalls 022, 023, 024 Discharges were *made from the oil/water separator vaults (Outfalls 022, 023, and 024)-throughout the month of May. No exceedences occurred.Outfall 025A Two continuous discharges occurred during the month of May. No exceedences occurred.Outfall 025B One continuous discharge occurred during the month of May. No exceedences occurred.Outfall 025C Six batch discharges occurred during the month of May. No exceedences occurred. Environmental Protection Agency SBK-L-10 10/Page 3 Outfall 025D Three batch discharges occurred during the month of May. No exceedences occurred.Outfall 027A One discharge was made from, the Cooling Tower to support maintenance activities during the month of May. No exceedences occurred.If you have questions on this matter, please contact me at (603) 773-7745.Sincerely, NextEra Energy Seabrook, LLC Michfael O'Keefe/Licensing Manager cc: New Hampshire Department of Environmental Services (NHDES)Water Division Wastewater Engineering Bureau 29 Hazen Drive, P.O.

1.0 INTRODUCTION

This report presents the results of acute and chronic toxicity tests completed on a series of composite effluent samples collected from NextEra Energy Seabrook Station, Seabrook, New Hampshire. Testing was based on programs and protocols developed by the US EPA (2002). A 48 hour static acute toxicity test was conducted using the mysid shrimp, Americamysis bahia, a 7 day modified acute and chronic toxicity test was conducted with the inland silverside, M. beryllina, and a 60 minute chronic fertilization assay was conducted with the purple sea urchin, A. punctulata. Testing was performed at EnviroSystems, Incorporated (ESI), Hampton, New Hampshire in accordance with the provisions of the NELAC Standards (2000).Acute toxicity tests involve preparing a series of concentrations by diluting effluent with control water.Groups of test organisms are exposed to each effluent concentration and a control for a specified period. In acute tests, mortality data for each concentration are used to calculate (by regression) the median lethal concentration, or LC-50, defined asthe effluent concentration which kills half of the test organisms. Samples with high LC-50 values are less likely to cause significant environmental impacts. The no-effect concentration is also determined to provide information about the level of effluent which would.have minimal acute effects in the environment. This Acute No Observed Effect Concentration (A-NOEC) is defined as the highest tested effluent concentration which causes no significant mortality. Chronic tests evaluate toxicity based on sublethal effects. Fertilization of Arbacia punctulata eggs or growth (weight) of Menidia beryllina are measured to determine effluent concentrations that have a significant impact on the organisms. Using Analysis of Variance techniques to evaluate the data, it is possible to determine the lowest concentration that had an effect (C-LOEC) and the highest concentration where no effect was observed (C-NOEC). A. punctulata fertilization data are also evaluated to determine the effluent concentration where a reduction in fertilization rates occurs. This is known as the Inhibition Concentration (IC).2.0 MATERIALS AND METHODS 2.1 General Methods Toxicological and analytical protocols used in this program follow procedures primarily designed by the EPA to provide standard approaches for the evaluation of toxicological effects of discharges on aquatic organisms, and for the analysis of water samples.2.2 Test Species When necessary, A. bahia and M. beryllina were acclimated to approximate test conditions prior to use in the assay and then transferred to test chambers using a large bore glass pipet, minimizing the amount of water added to test solutions. Male and female A. punctulata are maintained in separate chambers as recommended by protocol (EPA 2002).2.3 Effluent, Receiving Water and Laboratory Water Effluent and receiving water collection information is provided in Table 1. Samples were stored at4 0 C and warmed to 25+/-1°C prior to preparing test solutions. When necessary, effluent used in the A. bahia anM M. beryllina assays was salinity adjusted to 25+/-2 ppt and the effluent used in the A. punctulata assay was salinity adjusted to 30+/-2 ppt using artificial sea salts according to protocol (EPA 2002). Effluent and receiving water samples that were received at or above a salinity of 25+/-2 ppt did not require salinity adjustment (EPA 2002). Laboratory water was collected from the Hampton/Seabrook Estuary. This water is classified as SA-1 NextEra Energy Seabrook Station Effluent Evaluation, May 2010.Study Number 19693. Page 3 of 12 and has been used to culture marine test organisms since 1981.Total residual chlorine (TRC) was measured by amperometric titration (MDL 0.02 mg/L) in effluent and diluent samples. Samples containing 20.02 mg/L TRC were treated with sodium thiosulfate (EPA 2002).2.4 Bioassays Test concentrations for the assays were 100%, 50%, 25%, 12.5%, and 6.25% effluent.2.4.1 Americamysis bahia Acute Exposure Bioassay The 48 hour static acute assay was conducted at 25+/-1 °C with a photoperiod of 16:8 hours light*dark. Test chambers were 250 mL glass beakers with 200 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Survival and dissolved oxygen were recorded daily in all replicates. Temperature, pH, and salinity were measured in one replicate of each test treatment daily.2.4.2 Menidia beryllina Chronic Exposure Bioassay The 7 day static renewal chronic exposure assay was conducted at 25+/-1 °C with a photoperiod of 16:8 h6urs light:dark. Fish were maintained in 600 mL beakers containing 500 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Prior to daily renewals, survival and dissolved oxygen in all replicates were recorded and pH, salinity and temperature were measured in one replicate of each test treatment. Dissolved oxygen, salinity, pH, and temperature were measured in one replicate of each new test treatment. Survival data was analyzed to assess acute toxicity after the initial 48 hours of exposure.During the test, fish were fed -24 hour old Artemia nauplii twice a day. On Day 7 of the assay surviving fish were removed from test solutions, rinsed to remove any surface detritus and salts, and tranquilized using Finquel brand tricaine methanesulfonate. Fish were placed on tared containers and dried for 24 hours at 104'C to obtain dry weight to the nearest 0.01 mg. To obtain final dry weight/fish used for statistical comparisons, the net dry weight was divided by the number of organisms introduced at the initiation of the assay.2.4.3 Arbacia punctulata Chronic Fertilization Bioassay Test chambers were 20 mL glass vials with 5 mL of test solution in each of 4 replicates. Gametes were obtained by potassium chloride injection to induce spawning. Sperm were collected dry, diluted (see data appendix for final counts) and exposed .to effluent solutions for 60 minutes. Eggs -were introduced to sperm/effluent solutions and exposed for 20 minutes prior to the addition of preservative. Aliquots of preserved solution were counted to determine fertilized and unfertilized eggs.2.5 Data Analysis When necessary, statistical analysis of acute and chronic exposure data was completed using CETIS, Comprehensive Environmental Toxicity Testing System, software. The program computes acute and chronic exposure endpoints based on EPA decision tree guidelines specified in individual test methods. If survival in the highest test concentration is >50%, the LC-50 is obtained by direct observation of the raw data. For chronic exposure endpoints statistical significance was accepted at -<0.05.2.6 Quality Control As part of the laboratory quality control program, standard reference toxicant assays are completed on a regular basis for each.test species. These results, Table 2, provide relative health and response data while allowing for comparison with historic data sets..3.0 RESULTS AND DISCUSSION LC-50 and A-NOEC values from the A. bahia acute exposure assays are presented in Table 3. Data NextEra Energy Seabrook Station Effluent Evaluation, May 2010.Study Number 19693: Page 4 of 12 from the A. punctulata fertilization assay aresummarized in Table 4. Results of the chronic exposure assay completed using M. beryllina are provided in Table 5. A summary of water quality data collected during the assays is presented in Table 6. US EPA Attachment F toxicity test summary forms are irfcluded after the tables. Support data, including copies of laboratory bench sheets, can be found in Appendix A.3.1 Americamysis bahia Acute Exposure Bioassay Minimum test acceptability criteria require >90% survival in the control concentrations. Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 3 for test acceptability.

3.2 Arbacia

punctulata Chronic Fertilization Bioassay Protocol specifies a 70% to 90% fertilization rate and the MSDp for fertilization to be <25% forArbacia punculata (EPA 2002). Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 4 for test acceptability.

3.3 Menidia

beryllina Chronic Exposure Bioassay Minimum test acceptability criteria require 80% control survival, a mean dry weight of 0.500 mg/fish based on Day 7-survival, and the MSDp for biomass to be <28% for Menidia beryltina (EPA 2002).Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 5 for test acceptability.

1.0 INTRODUCTION

• This report presents the results of acute and chronic toxicity tests completed on a series of composite effluent samples collected from NextEra Energy Seabrook Station, Seabrook, New Hampshire.

Testing was based on programs-and protocols developed by the US EPA (2002). A 48 hour static acute toxicity test was conducted using the mysid shrimp, Americarnysis bahia, a 7 day modified acute and chronic toxicity test was conducted with the inlandsilverside, M. beryllina, and a 60 minute chronic fertilization assay was conducted with the purple sea urchin, A. punctulata. Testing was performed at EnviroSystems, Incorporated (ESI), Hampton, New Hampshire in accordance with the provisions of the NELAC Standards (2000).Acute toxicity tests involve preparing a series of concentrations by diluting effluent with control water.Groups of test organisms are exposed to each effluent concentration and a control for a specified period. In acute tests, .mortality data for each concentration are used to calculate (by regression) the median lethal concentration, or LC-50, defined as the effluent concentration which kills half of the test organisms. Samples with high LC-50 values are less likely to cause significant environmental impacts. The no-effect concentration is also determined to provide information about the level of effluent which would have minimal acute effects in the environment. This Acute No Observed Effect Concentration (A-NOEC) is defined as the highest tested effluent concentration which causes no significant mortality. Chronic tests evaluate toxicity based onsublethal effects. Fertilization of Arbacia punctulata eggs or growth (weight) of Menidia beryllina are measured to determine effluent concentrations that have a significant impact on the organisms. Using Analysis of Variance techniques to evaluate the data, it is possible to determine the.lowest concentration that had an effect (C-LOEC) and the highest concentration where no effect was observed (C-NOEC). A. punctulata fertilization data are also evaluated to determine the effluent concentration where a reduction in fertilization rates occurs. This is known as the Inhibition Concentration (IC).2.0 MATERIALS AND METHODS 2.1 General Methods Toxicological and analytical protocols used in this program follow procedures primarily designed by the EPA to provide standard approaches for the evaluation of toxicological effects of discharges on aquatic organisms, and for the analysis of water samples. , 2.2 Test Species When necessary, A. bahia and M. beryllina were acclimated to approximate test conditions prior to use in the assay and then transferred to test chambersusing a large bore glass pipet, minimizing the amount of water added to test solutions. Male and female A. punctulata are maintained in separate chambers as recommended by protocol (EPA 2002).2.3 Effluent, Receiving Water and Laboratory Water Effluent and receiving water collection information is provided in Table 1. Samples were stored at 4°C and warmed to 25+/-17C prior to preparing test solutions. When necessary, effluent used in the A. bahia and M. beryllina assays was salinity adjusted.to 25+/-2 ppt and the effluent used in the A. punctulata 'assay was salinity adjusted to 30+2 ppt using artificial sea salts according to protocol (EPA 2002).,Effluent and receiving water samples that were received at or above a salinity of 25+/-2 ppt did not require salinity adjustment (EPA 2002). Laboratory water was collected from the Hampton/Seabrook Estuary. This water is classified as SA-1-NextEra Energy Seabrook Station Effluent Evaluation, August 2010.Study Number 20062. Page 3 of 12 and has been used to culture marine test organisms since 1981.Total residual chlorine (TRC) was measured by amperometric titration (MDL 0.02 mg/L) in effluent and diluent samples. Samples containing 0.02 mg/L TRC were treated with sodium thiosulfate (EPA 2002).2.4 Bioassays Test concentrations for the assays were 100%, 50%, 25%, 12.5%, and 6.25% effluent.2.4.1 Americamysis bahia Acute Exposure Bioassay The.48 hour static acute assay was conducted at 25+/-1 'C with a photoperiod of 16:8 hours light:dark. Test chambers were 250 mL glass.beakers with 200 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Survival and dissolved oxygen were recorded daily in all replicates. Temperature, pH, and salinity were measured in one replicate of each test treatment daily.2.4.2 Menidia beryllina Chronic Exposure Bioassay The 7 day static renewal chronic exposure assay was conducted at 25+/-1 0C with a photoperiod of 16:8 hours light:dark. Fish were maintained in 600 mL beakers containing 500 mL of test solution in each of 4 replicates containing 10 organisms/replicate. Prior to daily renewals, survival and dissolved oxygen in all replicates were recorded and pH,, salinity and temperature were measured in one replicate of each test treatment. Dissolved oxygen, salinity, pH, and temperature were measured in one replicate of each new test treatment. Survival data was analyzed to assess acute toxicity after the initial 48 hours of exposure.During the test, fish were fed 24 hour old Artemia nauplii twice a day. On Day 7 of the assay surviving fish were removed from test solutions, rinsed to remove any surface detritus and salts, and tranquilized using Finquel brand tricaine methanesulfonate. Fish were placed on tared containers and dried for 24 hours at 104°C to obtain dry weight to the nearest 0.01 mg. To obtain final dry weight/fish used for statistical comparisons, the net dry weight was divided by the number of organisms introduced at the initiation of the assay.2.4.3 Arbacia punctulata Chronic Fertilization Bioassay Test chambers were 20 mL glass Vials with 5 mL of test solution in each of-4 replicates. Gametes were obtained by potassium chloride injection to induce spawning. Sperm were collected dry, diluted (see data appendix for final counts) and exposed to effluent solutions for 60 minutes. Eggs were introduced to sperm/effluent solutions and exposed for20 minutes prior to the addition of preservative. Aliquots of preserved solution were counted to determine fertilized and unfertilized eggs.2.5 Data Analysis When necessary, statistical analysis of acute and chronic exposure data was completed using CETIS, Comprehensive Environmental Toxicity Testing System, software. The program computes acute and chronic exposure endpoints-based on EPA decision tree guidelines specified in individual test methods. If survival in the highest test concentration is >50%, the LC-50 is obtained by direct observation of the raw data. For chronic exposure endpoints statistical significance was accepted at o <0.05.2.6 Quality Control As part of the laboratory quality control program, standard reference toxicant assays are completed on a regular basis for each test species. These results, Table 2, provide relative health and response data while allowing for comparison with historic data sets.3.0 RESULTS AND DISCUSSION LC-50 and A-NOEC values from the A. bahia acute exposure assays are presented in Table 3. Data NextEra Energy Seabrook Station Effluent Evaluation, August 2010.Study Number 20062. -Page 4 of 12 from the A. punctulata fertilization assay are summarized in Table 4. Results of the chronic exposure assay completed using M. beryllina are provided in Table 5. A summary of water quality data collected during the assays is presented in Table 6. US EPA Attachment F toxicity test summary forms are included after the tables. Support data, including copies of laboratory bench sheets, can be found in Appendix A.3.1 Americamysis bahia Acute Exposure Bioassay, Minimum test acceptability criteria require 290% survival in the control concentrations. Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 3 for test acceptability.

3.2 Arbaciapunctulata

Chronic Fertilization Bioassay Protocol specifies a 70% to 90% fertilization rate and the MSDp for fertilization to be <25% for Arbacia punculata (EPA 2002). Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 4 for test acceptability.

3.3 Menidia

beryllina'Chronic Exposure Bioassay Minimum test acceptability criteria require 80% control survival, a mean dry weight of 0.500 mg/fish based on Day 7. survival, and the MSDp for biomass to be <28% for Menidia beryllina (EPA 2002).Achievement of these results indicate that healthy test organisms were used and that the dilution water had no significant adverse impact on the outcome of the assay. See the Executive Summary and Table 5 for test acceptability.

Obtains EPA NPDES and Industrial Wastewater Discharge permit modifications and renewals.1.6 Imstructions 1.6.'1 Monitoring Monitoring parameters and frequencies of the various discharge pathways are specified in the permits. The permits should be referred to for specifics.

Sampling, analysis and quality assurance shall comply with EPA recommended procedures.

1.6.2 Discharge

Monitoring Reports On a monthly basis, a NPDES Discharge Monitoring Report (DMR) must be submitted to the EPA. This report includes NPDES permit exceedances, and a summary of monitoring results from the previous month.Discharge monitoring reports for the Industrial Wastewater Discharge Permit must be submitted to the Town of Seabrook Water and Sewer Department every six months, in January and July. This report includes permit exceedances, and a summary of monitoring results from the previous six month period.1.6.3 Permit Exceedances and Noncompliance All NPDES permit exceedances and noncompliances are required to be reported to the EPA in accordance with the NPDES Permit. All Industrial Wastewater Discharge Permit exceedances and noncompliances are required to be reported to the Town of Seabrook Water and Sewer Department. Reports shall include what was exceeded and the cause of the exceedance or noncompliance. Additionally, permit exceedances and noncompliances shall be documented and processed under the Seabrook Station corrective action program. (Reference the Operating Experience Manual [SSOE].)All discharges from the site are regulated. Any unauthorized use of a floor drain, storm drain, sink or sump could potentially cause a permit exceedance, and is therefore forbidden. There are many non-radiological materials used at Seabrook Station that, if discharged to the environment in an uncontrolled manner, could result in a violation of various regulatory requirements. These materials include chemicals, oil products and groundwater from dewatering activities. 2-1.2 NAEC Rev. 39 The Chemistry Manual (SSCP), procedure CP 9.3, "Non-Radiological Effluent Releases," provides instructions to control the discharge or release of non-radiological materials not specifically covered in the NPDES permit. The procedure provides a means to review releases and provide documentation for compliance purposes. The procedure applies to, but is not limited to:* Non-routine discharges of liquids to storm drains and floor drains which supply the storm drain system.Dewatering of excavations to storm drains.Washing of equipment near storm drains.CP 9.3 does not apply to rainwater and sanitary Waste discharges or Fire Protection System flushing surveillances which are addressed by other Station procedures. If there is any doubt as to the applicability of procedure CP 9.3, consult Chemistry Department supervisory personnel. It should be noted that discharges to all Protected Area storm drains, as well as storm drains near the Protected area, are routed to the Circulating Water System which discharges into the Atlantic Ocean. Some site storm drains and surface runoff are routed to the salt marsh. Therefore, any releases to a storm drain will be discharged to either the Atlantic Ocean or the salt marsh.Anyone requesting approval to release an effluent to the environment shall complete Section I of the Non-Radiological Release Permit, Form CP 9.3A, and should submit the form to the Chemistry Department at least 24 hours prior to the proposed release.1.6.4 Permit Modification or Renewal The NPDES permit is renewed every five years. Permit modifications can be requested in the interim. In addition, requests for changes to the NPDES permit shall be submitted to the Nuclear Regulatory Commission. If the facility is to be modified in such a way that it affects the NPDES permit, the EPA must provide prior approval of the necessary permit changes. Compliance with the NPDES permit is not only a requirement of the EPA, but is also a requirement of Appendix B (Environmental Protection Plan) to the NRC Operating License.The Industrial Wastewater Discharge Permit is renewed every three years. Permit modifications may be made under specific terms and conditions identified in the permit.Compliance with this permit is required under the Seabrook Sewer Use Ordinance. 2-1.3 NAEC Rev. 39

1.6.5 Environmental

Monitoring Program The Environmental Monitoring Program is implemented both off site and on site to meet the, sampling requirements of the National Pollutant Discharge Elimination System (NPDES) Permit. Representatives from the Environmental Protection Agency, N.H. Department of Environmental Services, N.H. Fish and Game Department and the U.S. National Marine Fisheries Service, review the Environmental Monitoring Program results and make recommendations on proposed program changes.Appendix B of the Seabrook Station Operating License, the Environmental Protection Plan, Nonradiological, states in part 2.0 that "Aquatic matters are addressed by the effluent limitations and monitoring requirements contained in NPDES Permit No.NH0020338 issued by the U.S. Environmental Protection Agency (Region I) on July 26, 1985. The NRC will rely on the U.S.E.P.A. and the NPDES Permit for regulation of matters involving water quality and aquatic biota." The offsite Environmental Monitoring Program is implemented by FPLE's Environmental Studies Contractor. Environmental studies for Seabrook Station began in 1969 and focused on station design and siting matters. Once these matters were addressed, a monitoring program was implemented during the preoperational period (1976 to 1990).The Environmental Monitoring Program is designed to determine whether Seabrook Station has affected the balanced indigenous population of fish, shellfish and wildlife in the coastal waters near Seabrook Station. The preoperational monitoring program established a baseline against which potential environmental impacts during the operational period (1990 to present) can be evaluated. Potential sources of station impact include entrainment/impingement in cooling water systems, exposure to the thermal plume and exposure to increased particulate material (dead organisms) settling from discharge, i.e., detrital rain. Major elements of the program include water quality, phytoplankton, zooplankton fish, macrobenthos, surface fouling panels, epibenthic crustacea, and soft-shell clam.Environmental samples are collected throughout the year by FPLE's's Environmental Monitoring Contractor. These samples are analyzed and the data derived from these analyses is evaluated to determine any environmental impact associated with Seabrook Station. Annual Environmental Monitoring Reports are ,developed which include the results of the previous year's monitoring program.2-1.4 NAEC Rev. 39 The onsite Environmental Monitoring Program is coordinated by the Licensing Department personnel. These programs are designed to assess potential station impacts associated with the impingement of fish and lobsters and the entrainment of ichthyoplankton (fish eggs and larvae) and bivalve larvae. The data collected under these programs is evaluated to determine if there is any indication of an environmental impact associated with station operation. The results of these studies are incorporated into the annual Environmental Monitoring Reports. The implementing station instructions are as follows: 1. ZN1 120.01 -Ichthyoplankton Entrainment Sampling Ichthyoplankton entrainment sampling is performed weekly (48 times per year). This program evaluates the number of ichthyoplankton entrained by the station's Circulating Water System (CWS). Entrainment sampling can be performed only when at least one CW pump is operating, when sufficient flow is available to supply ocean water to entrainment' sampling equipment.

2. ZN1 120.02 -Bivalve Larvae Entrainment Sampling* Bivalve larvae sampling is performed weekly from April to October. This program evaluates the number of bivalve larvae entrained by the station's Circulating Water System (CWS).* Entrainment sampling can be performed only when at least one CW pump is operating, when sufficient flow is available to supply ocean water to entrainment sampling equipment 3. ZN1 120.03 -Impingement Assessment Procedure Impingement assessments are performed at least twice per week to determine the number, type and size of fish and lobsters impinged by the station. Fish and lobsters are removed from screen wash debris and counted, identified and measured.

Results of the impingement assessment are incorporated into the annual Environmental Monitoring Reports.2-1.5 NAEC Rev. 39

3.0 MANAGEMENT

OF OZONE-DEPLETING SUBSTANCES

3.1 Purpose

The purpose of this section is to ensure compliance with Title VI of the Clean Air Act Amendments of 1990 (CAAA), governing ozone-depleting substances (ODSs). ODSs injure public health and the environment by destroying, ozone in the upper atmosphere. Additionally, ODSs are greenhouse gases; i.e., they promote global warming.3.2 Applicability This section applies to the following:

1. any appliance using and containing an ozone-depleting refrigerant, 2. purchase of any ODS for a nonessential use, as described below, and 3. to other related issues (e.g., certification of persons handling refrigerant; labeling of ODSs; identification of nonozone-depleting substitute products).

3.3 References

1. Title VI of the CAAA 2. 40 CFR Part 82 3.4 Definitions

3.4.1 Appliances

Any device which contains more than five pounds of a Class I or Class IH substance for use as a refrigerant and which is used for household or commercial purposes, including refrigerators, chillers, freezers, water coolers, and vending machines (reference 40 CFR 82.152[a]). 3.4.2- Class I or Clas II Ozone-Depleting Substance See list in Figure 2-3-1, List of Regulated ODSs.3.4.3 Small Appliances Appliances that are fully manufactured, charged and hermetically sealed in a factory and contain five pounds or less of refrigerant, including, but not limited to refrigerators and freezers designed for home use or for medical or industrial research, room air conditioners (including window air.conditioners and packaged terminal air heat pumps), dehumidifiers, under-the-counter ice makers, vending machines, and drinking water coolers (reference 40 CFR 82.152[v]). 2-3.1 NAEC Rev. 39

3.4.4 Commercial

Refrigeration Commercial refrigeration means appliances utilized in the retail food and cold storage warehouse sectors. Retail food includes the refrigeration equipment found in supermarkets, convenience stores, restaurants, and other food service establishments. Cold storage includes the equipment used to store meat, produce, dairy products and other perishable goods. All of the equipment contains large refrigerant charges, typically over 75 pounds.Refrigerated food storage equipment used in the Administration Building and General Office Building cafeterias are in this classification of equipment.

3.4.5 Industrial

Process Refrigeration Industrial process refrigeration means complex customized appliances used in the chemical, pharmaceutical, petrochemical and manufacturing industries. These appliances are directly linked to the industrial process. This sector also includes industrial ice machines, appliances used directly in the generation of electricity, and ice rinks. Where one appliance is used for both industrial process refrigeration and other applications, it will be considered industrial process refrigeration equipment if 50 percent or more of its operating capacity is used for industrial process refrigeration. Appliances used for regulating temperatures in control panel buildings and cooling equipment to cool computers are not industrial process refrigeration. No appliances currently in use at Seabrook Station are in this equipment classification. 3.4.6 Full Charge The amount of refrigerant required for normal operating characteristics and conditions of the appliance as determined by using one of the following four methods or a combination of the following four methods: 1. The equipment manufacturer's determination of the correct full charge of the equipment;

2. Determining the full charge by appropriate calculations based on component sizes, density of refrigerant, volume of piping, and all other relevant considerations;

3. The use of actual measurements of the amount of refrigerant added or evaluated from the appliance; and/or 4. The use of an established range based on the best available data, regarding the normal operating characteristics and conditions for the appliance, where the mid-point of the range will serve as the full charge, and where records are maintained in accordance with 40 CFR 82.166(q).

2-3.2 NAEC Rev. 39

3.4.7 Initial

Verification Test Those leak tests that are conducted as soon as practicable after the repair is completed. An initial verification test, with regard to the leak repairs that require the evacuation of the appliance or portion of the appliance, means a test conducted prior to the replacement of the full refrigerant charge and before the appliance or portion of the appliance has reached operation at normal operating characteristics and conditions of temperature and pressure. An initial verification test with regard to repairs conducted without the evacuation of the refrigerant charge means a test conducted as soon as practicable after the conclusion of the repair work.3.4.8 Follow-up Verification Test Those tests that involve checking the repairs within 30 days of the appliance's returning to normal operating characteristics and conditions. Follow-up verification tests for appliances from which the refrigerant charge has been evacuated means a test conducted after the appliance or portion of the appliance has resumed operation at normal operating characteristics and conditions of temperature and pressure, except in cases where sound professional judgment dictates that these tests will be more meaningful if performed prior to the return to normal operating characteristics and conditions. A follow-up verification test with respect to repairs conducted without evacuation of the refrigerant charge means a reverification test conducted after the initial verification test and usually within 30 days of normal operating conditions. Where an appliance is not evacuated, it is only necessary to conclude any required changes in pressure, temperature or other conditions to return the appliance to normal operating characteristics and conditions.

3.4.9 Reclamation

To reclaim refrigerant means to reprocess refrigerant to at least the purity specified in Appendix A to 40 CFR 82, subpart F (based on ARI Standard 700-1993, Specifications for Fluorocarbon and Other Refrigerants) and to verify this purity using the analytical methodology prescribed in Appendix A. In general, reclamation involves the use of processes or procedures available only at a reprocessing or manufacturing facility.3.4.10 Recovery To recover refrigerant means to remove refrigerant in any condition from an appliance and to store it in an external container without necessarily testing or processing it in any way.3.4.11 Recycle To recycle refrigerant means to extract refrigerant from an appliance and clean refrigerant for reuse without meeting all of the requirements for reclamation. In general, recycled refrigerant is refrigerant that is cleaned using oil separation and single or multiple passes through devices, such as replaceable core filter-driers, which reduce moisture, acidity, and particulate matter. These procedures are usually implemented at the field job site.2-3.3 NAEC Rev. 39

3.5 Responsibilities

3.5.1 Maintenance

Manager Ensures that work done on process equipment containing ozone depleting substances is performed by trained personnel and in accordance with approved procedures.

3.5.2 Nuclear

Training Manager Responsible for training and certification programs.3.5.3 Licensing Manager 1. Responsible for the coordination of reviews of substitute products for Class I and Class II ozone depleting substances utilizing Engineering input as required.2. Responsible for documentation and record retention of substitute product reviews.3.6 Requirements 3.6.1 Ban on Emissions of Ozone-Depleting Refrigerants

1. Emissions Ban 40 CFR 82.154(a) prohibits, in the course of maintaining, servicing, repairing or disposing of an appliance, commercial refrigeration, or industrial process refrigeration equipment, knowingly venting or otherwise knowingly releasing or disposing of any Class I or Class II substance (see Figure 2-3-1) used as a refrigerant in such appliance'or industrial process refrigeration.

2. Exempt Emissions 40 CFR 82 exempts emissions occurring when following EPA's required practices (see below). Further, the rule exempts small releases resulting from purging, connecting and disconnecting hoses to charge or service an appliance.

40 CFR 82 also does not apply to mixtures of nitrogen and R-22 that are used as holding charges or as leak test gases, i.e., not as refrigerant. Finally, refrigerant emissions in the course of normal operation of equipment are not prohibited. However, 40 CFR 82 requires repair of substantial leaks (see below.)3.6.2 Required Practices 40 CFR 82 requires the following, which are discussed below:* Use of certified recovery and recycling equipment* Evacuation to prescribed levels* Alternate practices where evacuation is not performed 2-3.4 NAEC Rev. 39

• Repair of certain leaking equipment.Recordkeeping o Reporting* Labeling o Purity check in limited cases 1. Use of Certified Equipment All persons opening appliances for maintenance, service or repair must evacuate the refrigerant in either the entire unit or the part to be serviced (if the latter can be isolated) to a system receiver or a recovery or recycling machine certified under 40 CFR 82.158(a).

NOTE Recovery partially into chilled cylinders and partially into certified equipment does not satisfy the rule. See §3.6.3 below.All persons disposing of appliances, except for small appliances containing less than 5 lbs. of refrigerant, must evacuate the refrigerant in the entire unit to a certified recovery or recycling machine. System dependent equipment cannot be used with appliances normally containing more than 15 pounds of refrigerant unless the equipment is permanently attached to the appliance as a pump-out unit (reference 40 CFR 82.156[c]).

2. Evacuation Levels Persons repairing, servicing, or disposing of appliances, except for small appliances, must evacuate to the levels in Figure 2-3-2, Evacuation Levels (reference 40 CFR 82.156[a][1]

& [3]). However, evacuation need not comply with this table if a. evacuation to the atmosphere is not to be performed after the completion of the work, and the work is not major. (Major work involves removing the compressor, condenser, evaporator, or auxiliary heat exchanger coil.)In this case, evaporation/pressurization (to 0 psig) to the atmosphere is permitted prior to the work. (See 58 FR 28676.)b. due to leaks in the appliance, evacuation to the levels in Figure 2-3-2 is not attainable, or would substantially contaminate the refrigerant being recovered (reference 40 CFR 82.156[a][1]).

c. the work involves only oil changes. Appliances may be evacuated to a pressure not to exceed 5 psig to perform oil changes. Alternatively, the oil can be recovered to a system receiver where the receiver will be evacuated, to atmospheric pressure.2-3.5 NAEC Rev. 39

3. Alternate Practices a. If evacuation to the atmosphere is not to be performed after completion of the work, and if the work is not major, the appliance must be (1) evacuated to a pressure no higher than 0 psig before it is opened if it is a high or very high pressure appliance, or (2) pressurized to 0 psig before it is opened if it is a low pressure appliance, without using methods, e.g., nitrogen, that require subsequent purging (reference 40 CFR 82.156[a][i]).

NOTE High pressure means the appliance use a refrigerant with a boiling point between-50 and 10 degrees Centigrade. Low pressure means the boiling point is above 10 degrees Centigrade. Very high pressure means the boiling point is below -50 degrees Centigrade.

b. If, due to leaks in the appliance, evacuation to the level described in Figure 2-3-2 is not attainable, or would substantially contaminate the refrigerant being recovered, the technician must (1) isolate leaking from nonleaking components wherever possible, (2) evacuate nonleaking componentsto be opened to the levels specified in Figure 2-3-2, and (3) evacuate leaking components to be opened to the lowest level that can be attained without substantially contaminating the refrigerant.

This cannot exceed 0 psig (reference 40 CFR 82.156[a][2][ii]).

4. Leaking Equipment Substantial leaks of equipment containing a charge of 50 pounds or more must be repaired (reference 40 CFR 82.156[i]).

Substantial means a 35% annual leak rate for industrial process and commercial refrigeration; 15% for all other covered equipment. NOTE Air conditioning equipment and systems used for area and space cooling are considered comfort cooling appliances and are subject to the 15% annual leak rate limit. This includes control building A/C units and other air conditioning equipment used for cooling control boards and electrical panels.For leakage in industrial process and commercial refrigeration systems: (a) Within 30 days of discovering the leak, the owner must repair the leak or develop a one-year retrofit or retirement plan for the leaking equipment. 2-3.6 NAEC Rev. 39 (b) The plan (or a legible copy) must be kept at the site of the equipment and work to retrofit or retire must be completed within one year.(c) The owner may obtain a reasonable extension beyond 30 days when delayed by the requirements of other applicable laws/regulations, or the unavailability of a suitable replacement refrigerant With a lower ozone depletion potential.(d) If within these circumstances, the owner must notify EPA within 6 months after the 30 day period following discovery of the leak.(e) Records necessary to allow EPA to determine that these provisions apply and the length of time necessary to complete the work must be submitted to EPA and maintained on site. Further, EPA must approve the extension (40 CFR 82.156(a)(7)(i).(f) The owner generally has one year to complete a retrofit of industrial process equipment. However, an additional one year period is available (40 CFR 82.156(a)(7)(ii) Where: (1) The equipment is custom built.(2) Delivery will take over 30 weeks.(3) The owner notifies EPA (no permission is required). (4) The owner maintains records of these circumstances. No EPA permission is required when these criteria are met.NOTE Once a leak has been repaired, if a new leak occurs, the annual leak rate is recalculated from 0. That is, previous leaks (if properly repaired) are not counted in computing new leaks.For appliances not classified as industrial process or commercial refrigeration, EPA notification is not required, but the one-year retrofit or retirement plan must be made available on request.5. Recordkeeping Vendors servicing appliances normally containing over 50 pounds of refrigerant must provide FPLE Seabrook With documentation indicating the amount of refrigerant added to the appliance (reference 40 CFR 82.166[]). Standard vendor receipts satisfy these requirements. This documentation is not required for appliances containing less than 50 pounds of refrigerant. 2-3.7 NAEC Rev. 39 For industrial process and commercial refrigeration equipment applications under a retrofit plan: Where the owner takes more than one year to complete a retrofit of industrial process equipment, it must maintain records documenting the circumstances set forth in 40 CFR 82.156(a)(7)(ii). The owner must keep servicing records documenting the date and type of service, as well as the quantity of refrigerant added (reference 40 CFR 82.166[k]). Additionally records should include the following:

a. Identification of the facility.b. The leak rate.c. The method used to determine the leak rate and full charge.d. The date a leak rate of greater than the allowable annual leak rate was discovered.

e. The location of the leak(s) to the extent determined to date.f. Any repair work that has been completed and the date that work was completed.

g. Basis for repairs exceeding the allowed 30-day period.h. Repair plans and schedules for repairs beyond the allowed 30-day interval.i. Dates and types of all initial and follow-up verification tests and the test results.6. Reporting Information listed in 5a through 5i above must be reported to the EPA within 30 days of discovery of leakage in excess of allowable limits.7. Labeling See §3.6.8.8. Purity Recycled Class I or Class II refrigerant which is to be conveyed to another entity must be cleaned to the ARI 700 purity standard and chemically analyzed to verify that it meets this standard.

Only certified reclaimers are authorized to process used refrigerant. Only certified laboratories are authorized to perform the required analysis of reclaimed refrigerant. However, intra-company transfer of refrigerant is not subject to this requirement when both entities are wholly owner subsidiaries of the parent company.2-3.8 NAEC Rev. 39

3.6.3 Guidance

on Work Practices 1. Management of Refrigerant Cylinders should be kept in a clear, dry area, below 125°F. Cylinders 30-50 pounds may be kept in a tool crib where there is mechanical ventilation or the air volume exceeds 5000 cubic feet. Cylinders 125-150 pounds may be kept in a warehouse or mechanical room having normal ventilation for standard manufacturing. Empty cylinders should be refilled with the same type of refrigerant they contained formerly (i.e., the same cylinder should not be filled with R-12;emptied; then refilled with R-13).2. Evacuation of Refrigerant into Chilled Cylinders Some facilities have evacuated refrigerant from large (e.g., 800 pound) air conditioning systems through a thermal process, taking refrigerant into a large cylinder snurrounded by nitrogen coils, that condensed it. The last amount of refrigerant was evacuated into a piece of certified machinery, resulting in a total evacuation satisfying the 95% evacuation level. Although 40 CFR 82 does not address this situation, EPA has stated that this practice does not conform to the rule because it is a pressurized system, not a push-pull. Therefore, this practice will no longer be permitted.

3.6.4 Preparing

Equipment for Disposal I1. Sticker on All Covered Equipment While In Service To ensure that refrigeration equipment or air conditioners are not disposed of with their refrigerant intact, appliances shall have .a sticker or tag affixed which states,"Do not discard in trash unless refrigerant has been evacuated. Contact __ to arrange for evacuation." The sticker or tag shall have another blank to be signed by the person evacuating the appliance. (See Figure 2-3-3, Illustration of Appliance Sticker Warning.)2. Documentation of Evacuation After evacuating any appliance bearing the sticker described above, complete the blank indicating evacuation. Additionally, NAEC FORM 2-3A, Documentation of Removal of Refrigerant and Refrigerant Contaminated Oil, shall be completed. The original of this document shall be conveyed with the appliance to the scrapper/recycler. A copy shall be kept in the file of the party performing evacuation. 2-3.9 NAEC Rev. 39

3. Ensuring Appliance Capacitor Is PCB Free If an appliance capacitor does not contain PCBs, it should, be labeled "PCB free." If the capacitor lacks this label, the capacitor shall be removed from the appliance and disposed of as PCB waste.3.6.5 Certification Requirements for Persons Working with or Buying Refrigerant

1. Federal Requirement:

HVAC Servicing Persons who maintain, service, repair or dispose of appliances that could reasonably be expected to release a Class I or H1 substance into the atmosphere must have EPA technician certification. However, no certification is required for persons disposing of small appliances. Refer to 40 CFR 82.161(a).

2. State Requirement:

HVAC Servicing There is no state law or regulation in New Hampshire requiring licensing of persons working with ozone-depleting 'refrigerant.

3. Federal Requirement:

Purchase of Refrigerant Generally, Class I or Class II substances may be sold only to certified technicians or manufacturers. However, when the substance will be charged into equipment by a certified technician, the buyer need not be certified (reference 40 CFR 82.154[n][1]-[6]). FPLE Seabrook should provide sellers with at least one copy of a technician's certification from a certified employee.NOTE Apprentices may not purchase regulated refrigerant. Sale of R-12 in containers smaller than 20 pounds, for use in motor vehicles, is restricted to technicians certified under EPA's motor vehicle air conditioning regulations.

4. State Requirement:

Purchase of Refrigerant There is no state law in New Hampshire restricting who may purchase ODSs.3.6.6 Preference for Nonozone-Depleting Refrigerants The purchase of nonozone-depleting refrigerant systems is performed if the cost of purchase and maintenance (including refrigerant) is less than/equal to the cost of alternative systems. FPLE Seabrook does not advocate discarding functioning systems that use ozone-depleting refrigerants. 2-3.10 NAEC Rev. 39

3.6.7 Management

of Appliance Oil 1. Disposal of Oil HVAC oil is typically handled as a hazardous waste. Contact the Hazardous Waste Coordinator to determine the proper, method of disposal.2. Evaporation of CFCs from Oil Generators need not remove CFCs from CFC contaminated oil (reference 58 FR 28677). Accordingly, evaporation of CFCs from this oil and delivery of this oil to metal scrappers do not violate the ban on emissions of ODSs.3. Removal/Nonremoval of Oil Unless a particular vendor instructs otherwise, motors, compressors containing small amounts of oil may be included in scrap metal sent to vendors. Oil should be removed from appliances where it is readily feasible to do so (e.g., there is a valve or opening to remove the oil). When oil has been removed, contact the Hazardous Waste Coordinator to determine the proper handling of it. NAEC FORM 2-3A, Documentation of Removal of Refrigerant and Refrigerant Contaminated Oil, should be completed to indicate that the oil has not become contaminated with halogens except through contact with refrigerants.

3.6.8 Labeling

Containers containing a Class I or Class II substance must bear a warning statement printed in a legible, clear and conspicuous fashion. The warning must state the following: "WARNING: Contains [insert name of substance], a substance which harms public health and environment by destroying ozone in the upper atmosphere." See Figure 2-3-4, Warning Label for Containers Containing ODSs, for a sample.This requirement applies to all such containers, including containers which do not leave the facility.Containers should also bear the OSHA Right to Know label (reference the Hazard Communications Reference [SHCR]).3.6.9 Ozone-Depleting Solvents 1. Nonessential Uses 40 CFR 82 prohibits the sale or distribution in interstate commerce of ODSs for certain "nonessential" uses. Covered ODSs are those listed in Class I (group I or group II1) or Class II (see Figure 2-3-1.) (Reference 40 CFR 82.60[a].) Nonessential products include "any aerosol product or other pressurized dispenser... including industrial uses" containing one of these ODSs (reference 40 CFR 82.66[d]). 2-3.11 NAEC Rev. 39

2. Essential Uses 40 CFR 82 allows sale and distribution of cleaning fluid for electronic and photographic equipment when sold to a commercial purchaser (reference 40 CFR 82.66[b][2]).

Buyers need to present documentation of commercial status by presenting a local business license number, federal employer identification number, or state sales tax exemption number (reference 40 CFR 82.62[b]).

3. Lubricants and Cleaning Fluids The ban does not apply to lubricants, coatings, or cleaning fluids for electrical or electronic equipment which contain CFC- 11, CFC-12, or CFC- 113 for solvent purposes but which contain no other CFCs.4. 1,1,1 -trichloroethane By Executive Order, new production of 1,1,1-trichloroethane was banned after January 1, 1996. For a discussion of substitute products for parts cleaning, see§3.6.11 below.3.6.10 Use of Ozone-Depleting Products for Specific Utility Functions 1. Linemen's Gloves Use of CFC-1 13 (or other covered ODSs) for machinery that tests the protective sleeves of linemen's gloves is a nonessential use. Remaining stocks may be used indefinitely.

Alternative substances includeC6-F14.

2. Carbon Filter Banks Under 40 CFR 82 regulations, use of CFC-1 1 in testing carbon filter banks at nuclear plants is implicitly deemed nonessential.

However, the EPA has issued an exemption for purchase for this purpose.3. Transformers Use of CFC-12 (or other covered ODSs) to test for leaks in large transformers is nonessential. Remaining stocks may be used indefinitely. As an alternative, EEI and GE recommend (in order of descending preference) use of soap bubbles, sulfur hexafluoride, or helium.4. Condensers Use of CFC-12 (or other covered ODSs) to locate leaks in condensers is nonessential. Remaining stocks may be used indefinitely. 2-3.12, NAEC Rev. 39

5. Cleaning Out HVAC Systems Use of ODSs (especially R-l 1) to flush out HVAC systems whose compressors have overheated complies with CAAA regulations, assuming the flushout is done following the required practices described above (§3.6.2).

If flushout is performed, hard piping or hose clamps should be used to prevent evaporation. Ideally, facilities should use an alternative practice described below: cleaning the unit with acid core filter dryer, changing the oil, then testing the new oil for the presence of acid. Rather than using R-l Ito flush out systems, the following. method is recommended.

a. Remove a sample of oil from the compressor and test for acid using a sporian acid test kit. Protective equipment is recommended.

b. Reclaim the system refrigerant into certified equipment, either on site or at a reclamation facility.c. Install a new compressor.

d. Replace the liquid line moisture drier with an acid core filter. If it is a severe burnout, indicated by carbon or soot exiting the compressor housing into the discharge line, install a suction line acid core filter.e. Charge the system with clean refrigerant and run the compressor in normal system operation.

f. Sealed hermetic compressor Run the system for 8 hours. Remove the suction line acid core filter and replace the liquid line acid core filter with a moisture drier. This completes the process.g. Semihermetic compressor Run the system for 4 hours, shut it down, and take an oil sample. Replace all acid core filters and compressor oil. If the oil sample shows no acid, run the system for 8 more hours. Take another oil sample test. If no acid is indicated, then remove the acid core filters and install only a liquid line moisture drier to complete the process.If after the 4-hour initial run, the oil sample indicates acid, repeat the initial 4-hour step until the oil sample test indicates no acid. At this point, run the system for 8 more hours. Take another oil sample test. If no acid is indicated, then remove the acid core filters and install only a liquid moisture drier to complete the process.6. Portable fire extinguishers that contain ClassII ozone depleting substances (HCFCs) and are used in commercial, industrial or non-residential applications are exempt from thecurrent ban on use of these substances.

2-3.13 NAEC Rev. 39

7. EPA has finalized rulemaking that removes the exemption from laboratory applications of CFCs in analytical methods' for oil and grease and total hydrocarbons.

Based on the rulemaking, no further purchases of CFC-1 13 will be allowed for use in EPA Methods 413.1, 413.2, 418.1 and 9070; however, existing stocks may continue to be used. The only other lab application of CFC- 113 is particulate testing -of fuel oil in accordance with procedure CS0924.06 and ASTM standard D-2276, 1973. This procedure may continue to be used until January 1, 2006, under the current extension of the laboratory applications exemption. The Chemistry Department is currently evaluating new testing procedures under ASTM D-6217 as a possible replacement for this procedure. NOTE Consult the equipment manufacturer when in doubt or to ensure compliance with manufacturer's warranties. 3.6.11 Substitute Products 1. EPA Policy Under EPA's Significant New Alternatives Policy (SNAP) it is unlawful to replace any Class I or Class II substance with a substitute that may present adverse health or environmental effects. (A product not being employed as a substitute for a CFC or HCFC can still be used.) However, a label of "unacceptable" or no label for a product that is a substitute means that the substitute cannot be lawfully used.EPA review and approval of substitutes is required before they can be used in applications currently served by Class I or Class II substances. EPA classifies substitutes or alternative technology as follows:* Acceptable

• Acceptable subject to use conditions
• Acceptable subject to narrow use limits* Unacceptable
• Pending Substitution requests will be addressed through the chemical review process specified in Procedure EP 2.1. Substitute products will be evaluated for acceptability by Licensing with Engineering support as requested to determine if the proposed substitute product is acceptable for use on the affected equipment.

No substitute products will be used without a formal review by Licensing. If a substitute product has been designated by EPA as "acceptable subject to use conditions," end users must make reasonable efforts to determine that other alternatives are not feasible due to safety, performance or technical reasons and must document this assessment. The documentation must include 2-3.14 NAEC Rev. 39 0 descriptions of substitutes examined and rejected,* descriptions of processes or products in which the substitute is needed, and a statement of the reason for rejection of other alternatives. This documentation must be kept on file in order to demonstrate compliance with EPA requirements (Ref. 40 CFR 82.180(b)(2)). If a substitute product is designated by EPA as "acceptable subject to narrowed use limits," end users are expected to contact vendors of alternatives to explore with experts whether or not other acceptable substitutes are technically feasible for the process, product or system in question. End users must document these efforts, including:

• descriptions of substitutes examined and rejected,* descriptions of processes or products in which the substitute is needed,* a statement of the reason for rejection of other alternatives,* the anticipated date other substitutes will be available, and* the projected time for switching to other available substitutes.

This documentation must be kept on file in order to demonstrate compliance with EPA requirements (Ref. 40 CFR 82.180(b)(3)). Refer any substitution requests to Engineering for performance and documentation of the required reviews. Engineering will also evaluate the use of the substitute products for acceptability with the manufacturers of the affected equipment. No substitute products shall be used without a formal review by Engineering. 'Contact the Licensing Department for current information on substitute products reviewed by EPA.2. Substitute Refrigerants Under the SNAP, most HCFCs are acceptable transitional refrigerants. However, HCFC 141b is an unacceptable substitute for CFC-1 1 in new centrifugal chillers.Further, HCFC 22/HFC 142b/CFC-12 (blend) is an unacceptable substitute for CFC-12 in commercial comfort air conditioning systems. EPA has also approved use of HFC, but warns it contributes to global warming. HCFCs (but not HFCs)are subject to the refrigerant recovery practices described in §3.5.2 and these practices are recommended for HFCs. EPA recommends that users of substitute refrigerants comply with ASHRAE Standard 15 (Mechanical Refrigeration) andýASHRAE Standard 34 (Refrigerants). For guidance on selecting a substitute, contact Engineering. 2-3.15 NAEC Rev. 39

3. Substitute Parts Cleaning Under the SNAP, most HCFCs are unacceptable substitutes for CFC-1 13 and MCF in metals, electronics and precision cleaning.

This ban is in effect for use in new equipment; use in existing equipment was discontinued on January 1, 1996.See 59 FR 13094. Acceptable substitutes for parts cleaning includehydrocarbons, perfluorocarbons (PFCs), absorption, and new technologies, such as chlorine compression. 3.6.12 Halon Halon should be stored in DOT/OSHA approved cylinders at temperatures between 50 and 90°F. Cylinders should be protected from mechanical damage.3.6.13 Reporting of Refrigerant Releases CERCLA requires reporting releases of 5000 pounds or more of R-1 1 or R-12.(See 40 CFR 302.4.) The CAAA have no additional reporting requirements for release of CFCs. However, substantial leaks from equipment containing a charge of 50 pounds or more must be repaired.2-3.16 NAEC Rev. 39 Figure 2-3-1 List of Regulated ODSs (Sheet 1 of 2)List of Class 1 Substances Group I: chlorofluorocarbon-1 1 (CFC-11).chlorofluorocarbon-12 (CFC- 12)chlorofluorocarbon-113 (CFC- 113)chlorofluorocarbon-114 (CFC- 114)-chlorofluorocarbon-115 (CFC- 115)Group II: halon-1211 halon-1301 halon-2402 Group III: chlorofluorocarbon-13 (CFC-13)chlorofluorocarbon-1 11 (CFC-1 11)chlorofluorocarbon-112 (CFC- 112)chlorofluorocarbon-211 (CFC-21 1)chlorofluorocarbon-212 (CFC-212)chlorofluorocarbon-213 (CFC-213)chlorofluorocarbon-214 (CFC7214)chlorofluorocarbon-215 (CFC-215)chlorofluorocarbon-216 (CFC-216)chlorofluorocarbon-217 (CFC-217)Group IV: carbon tetrachloride Group V: methyl chloroform 2-3.17 NAEC Rev. 39 Figure 2-3-1 List of Regulated ODSs (Sheet 2 of 2)List of Class II Substances: hydrochlorofluorocarbon-21 (HCFC-21)hydrochlorofluorocarbon-22 (HCFC-22)hydrochlorofluorocarbon-31 (HCFC-31)hydrochlorofluorocarbon-121 (HCFC-121) hydrochlorofluorocarbon-122 (HCFC-122) hydrochlorofluorocarbon-123 (HCFC-123) hydrochlorofluorocarbon-124 (HCFC- 124)hydrochlorofluorocarbon-131 (HCFC- 131)hydrochlorofluorocarbon-132 (HCFC-132) hydrochlorofluorocarbon-.133 (HCFC-133) hydrochlorofluorocarbon-141 (HCFC- 141)hydrochlorofluorocarbon-142 (HCFC-142) hydrochlorofluorocarbon-221 (HCFC-221) hydrochlorofluorocarbon-222 (HCFC-222) hydrochlorofluorocarbon-223 (HCFC-223) hydrochlorofluorocarbon-224 (HCFC-224) hydrochlorofluorocarbon-225 (HCFC-225) hydrochlorofluorocarbon-226 (HCFC-226) hydrochlorofluorocarbon-231 (HCFC-231) hydrochlorofluorocarbon-232 (HCFC-232) hydrochlorofluorocarbon-233 (HCFC-233) hydrochlorofluorocarbon-234 (HCFC-234) hydrochlorofluorocarbon-235 (HCFC-235) hydrochlorofluorocarbon-241 (HCFC-241) hydrochlorofluorocarbon-242 (HCFC-242) hydrochlorofluorocarbon-243 (HCFC-243) hydrochlorofluorocarbon-244 (HCFC-244) hydrochlorofluorocarbon-251 (HCFC-251) hydrochlorofluorocarbon-252 (HCFC-252) hydrochlorofluorocarbon-253 (HCFC-253) hydrochlorofluorocarbon-261 (HCFC-261) hydrochlorofluorocarbon-262 (HCFC-262) hydrochlorofluorocarbon-27 1 (HCFC-271) 2-3.18 NAEC Rev. 39 Figure 2-3-2 Evacuation Levels TABLE 1 REQUIRED LEVELS OF EVACUATION FOR APPLIANCES EXCEPT FOR SMALL APPLIANCES, MVACS, AND MVAC-LIKE APPLIANCES Type of Appliance Inches of Mercury Vacuum*Using EquipmentManufactured: Before On or after Nov. 15, 1993 Nov. 15, 1993 HCFC-22 appliance** normally containing less than 200 0 0 pounds of refrigerant HCFC-22 appliance** normally containing 200 pounds or 4 10 more of refrigerant Other high-pressure appliance** normally containing less than 4 10 200 pounds of refrigerant (CFC-12, -500, -502, -114)Other high-pressure appliance** normally containing 200 4 15 pounds or more of refrigerant (CFC-12, -500, -502, -114)Very high-pressure appliance (CFC-13, -503) 0 0 Low-pressure appliance (CFC- 11, HCFC-123) 25 25 mm Hg'absolute*Relative to standard atmospheric pressure of 29.0" Hg.**Or isolated component of such an appliance. 2-3.19 NAEC Rev. 39 Figure 2-3-3 Illustration of Appliance Sticker Warning DO NOT DISCARD IN TRASH UNLESS REFRIGERANT HAS BEEN EVACUATED CONTACT TEL.TO ARRANGE FOR EVACUATION Refrigerant has been removed Signed Date 2-3.20 NAEC Rev. 39 Figure 2-3-4 Warning Label for Containers Containing ODSs WARNING: Contains a substance which harms public health and environment by destroying ozone in the upper atmosphere. 2-3.21 NAEC Rev. 39

4.0 MANAGEMENT

OF ASBESTOS-CONTAINING MATERIALS 4.1 Purpose This section outlines the requirements for handling, removing, and disturbing asbestos-containing material. This section identifies the FPLE Seabrook responsibilities and program elements to control asbestos fiber emissions as well as actions required to meet State and Federal environmental regulations.

4.2 Overview

1. Asbestos is a naturally occurring noncombustible chemical resistant fibrous silicate mineral with many useful properties; it is used as acoustical plaster, pipe insulation, building panels, floor covering, and fire proofing.2. The inhalation of asbestos fibers can produce asbestosis (lung disease) and lung cancer.As a result, this material is regulated tominimize health risks associated with exposure.However, asbestos-containing materials in a solid state, good repair, not subject to handling, and not likely to emit airborne fibers are not generally considered hazardous.

3. The Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) have issued regulations to reduce human exposure to asbestos.The EPA has issued the National Emissions Standards Hazardous Air Pollutants (NESHAPS), which includes regulations to prevent visible emissions of asbestos particles into the air. OSHA regulations apply to all workplace activities involving asbestos fibers.The OSHA standard specifies acceptable levels of airborne exposures for workers, engineering and administrative controls, work practices, and medical surveillance.

4.3 Applicability

1. To the greatest extent possible, Seabrook Station was built to be free of products that contain asbestos.

However, some asbestos-containing materials may be installed at Seabrook Station or in storage. Refer to the Safety and Health Manual (NASH) for details.2. These requirements conform with all applicable environmental federal and state regulations and shall be adhered to by all affected company employees.

3. Applicable federal and state regulations must be followed even where specific functional procedures do not exist.4. The Safety and Health Manual (NASH) focuses on the health and safety issues dealing with minimizing worker exposure to asbestos fibers.2-4.1 NAEC Rev. 39

4.4 References

Several federal and state environmental regulatory agencies control various aspects of asbestos.A summary of each agency, its respective responsibility, and specific references listed below is found in Figure 2-4-1.1.

4.8.2 Notification

Requirements

1. Planned demolitions, renovations and removal/abatement of ACM require 10-day advance notification to federal, state and local agencies.

The EPA notification form is shown in Figure 2-4-4. State and local notification can be made by submitting a copy of the notification form to NHDES Air Resources Division and the Town of Seabrook Building and Health Department. When multiple demolition or renovation projects are planned for a calendar year, the advance notification may be made to EPA and NHDES I 0-days before the start of the calendar year. This notification must include the planned work scope. Follow-up notifications must be made prior to the start of each demolition or renovation activity in the scope of work. Demolition and renovation activities not identified within this work scope remain subject to the 10-day advanced notification requirement.

2. EPA requires advance notification of renovation when the cumulative amount of ACM to be removed is equal to or greater than 260 linear feet, or 160 square feet or 35 cubic feet. EPA also requires advance notification whenever a building or structure will be demolished, even if there is no ACM present.

4.8.4 Safety

and Health Controls Safety and health controls shall be implemented in accordance with the Safety and Health Manual (NASH).4.8.5 Employee Training and Certification

1. Employees required to work with asbestos or who may be exposed above the action level must receive asbestos training in accordance With NESHAP, OSHA and state standards (see the SAfety and Health Manual).2. The Maintenance Manager shall ensure that all asbestos workers receive the required training and ensure that training records are maintained locally.3. Every renovation project must have at least one onsite management level person who has received training on the NESHAP provisions and methods for complying with them.4. The Maintenance Manager is responsiblefor ensuring New Hampshire DES asbestos worker certificates are obtained.4.8.6 Emission Controls 1. NESHAP requires that as much asbestos-containing material as possible be removed before doing any work on facility components that would serve to break up, disturb or preclude access to material for subsequent removal of asbestos-containing materials.

Regulated asbestos-containing materials need not be removed if the following conditions are met: a. It is Category I nonfriable asbestos (packings, gaskets, resilient floor covering, and asphalt roofing containing more than 1% asbestos) material that is not in poor condition and is not friable.b. It is on a facility component that is encased in concrete or other similar hard material and is adequately wet whenever exposed during demolition. 2-4.10 NAEC Rev. 39

c. It was not accessible for testing and was, therefore, not discovered until after demolition began and, as a result of demolition, the material cannot be safely removed. If not removed for safety reasons, the exposed asbestos must be treated as asbestos-containing waste material and adequately wet at all times until disposed.d. They are Category II nonfriable asbestos-containing material (materials exclusive of Category I asbestos containing more than 1% asbestos that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure) and the probability is low that the materials will become crumbled, pulverized, or reduced to powder during demolition*

2. The "competent" job supervisor shall ensure that, the appropriate asbestos tent containment and engineering controls including HEPA ventilation and wet methods are implemented to ensure "no visible asbestos emissions to the environment" during the asbestos work as required by the NESHAP regulations.

In addition, a competent person must be present during demolition of any building structure to ensure compliance with EPA Standards.

3. Waste water generated during asbestos abatement shall be HEPA filtered prior to discharge.

The filters shall then be disposed of as asbestos waste.4. Friable asbestos waste must be transported to the ground via dust-tight chutes or containers if they have been removed or stripped more than 50 feet above ground level.5. Where damage to pipe covering and boiler jackets is limited, the easiest abatement method is repair.6. Plastering these openings with nonasbestos materials can be done to restore open joints, damaged areas, or areas around valves and flanges.7. Duct tape should not be used as a long-term solution since it becomes brittle after exposure to high temperatures.

8. Where large portions of the material must be removed, containment barriers or glovebags should be used.4.8.7 Abatement and Removal Options Abatement and removal options are defined in the NASH or are provided by the Safety Staff for each activity.4.8.8 Asbestos Disposal Asbestos must be disposed of at state or federal authorized facilities.

The contracted abatement services or the Hazardous Waste Coordinator arranges for appropriate transportation and disposal.2-4.11 NAEC Rev. 39 r Radioactively Contaminated Asbestos Notify the Radwaste Department Supervisor as soon as possible (30 days if possible) prior to the removal process to determine and schedule the appropriate shipping containers necessary to support the work. The Radwaste Department Supervisor will be responsible for coordinating the packaging and shipping the radioactively contaminated asbestos off site for processing or for onsite storage.Nonradioactive Asbestos The instructions for the disposal of nonradioactive asbestos are contained in the NASH or are provided by the Safety Staff.4.8.9 Transportation of Asbestos See Chapter 3 for information on transporting DOT hazardous materials. 4.8.10 Contractors

1. All asbestos abatement contractors must be licensed/certified according to applicable state DES regulations.

2. Asbestos abatement contractors are responsible for complying with all state and federal regulations concerning asbestos abatement, transportation, and disposal.3. The department responsible for administering the asbestos abatement contract shall monitor contractor compliance.

4.8.11 Spills/Releases to the Environment

1. Under the authority of CERCLA, EPA lists asbestos as a "Hazardous Substance." CERCLA provisions do not apply unless asbestos is released into the ambient air or environment (air, water, land) outside a building.

As a Clean Water Act pollutant, asbestos is also subject to reporting when one pound of asbestos is released into waterways.

2. FPLE Seabrook must report to EPA's CERCLA National Response Center whenever one pound of friable asbestos is released to the environment.

A spill of one pound or more of asbestos shall be immediately reported to the following agencies: NOTE The reporting requirement is based on the amount of asbestos, not weight of the asbestos-containing material, released.a. New Hampshire Department of Safety Hazardous Material Team b. National Response Center c. Air Resources Division 2-4.12 NAEC Rev. 39 4.8.12 ADplicabilitv of RCRA Disposal Requirements to Asbestos Wastes NHDES regulates asbestos waste as a solid (non-hazardous) waste.

This is a voluntaryand cooperative agreement between FPLE Seabrook, the EPA and other utility and non-utility organizations to take proactive steps toward reducing emissions of sulfur hexafluoride gas to the atmosphere.

Sulfur hexafluoride (SF 6) emissions are recognized as a contributing cause of global warming. This section outlines SF 6 management, recordkeeping and reporting requirements under this program.6.2 Overview 1. Sulfur hexafluoride (SF 6) is recognized as a "greenhouse gas" which, along with other gases such as carbon dioxide, methane, and nitrous oxide, contributes to global warming.SF 6 is the least prevalent of the greenhouse gases in the atmosphere; however, it is very effective in reflecting infrared radiation back to earth and heating the surface.2. SF 6 is used for electrical insulation and for arc quenching and current interruption in, equipment used in the transmission and distribution of electricity. At Seabrook, this gas is contained in the 345.-kV switchyard breakers and bus ducts. The total system SF 6 inventory is 42,351 lbs.3. SF 6 emissions from electric power systems are the result of unavoidable releases from properly functioning equipment (due to static and dynamic operation) and from leakage (e.g., due to old and/or deteriorated gaskets or seals). Additionally, emissions may occur when gas is either transferred into equipment or extracted from it for disposal, recycling, or storage.4. Emissions of SF 6 are not currently subject to federal regulations. Emissions are regulated under NH Air Toxic rules and are subject to emission inventory reporting requirements under the facility Title-V Permit.6.3 Applicability In accordance with the FPLE Seabrook Policy Statement, programs will be implemented to accomplish the following objectives to the degree technically and economically feasible:* To recycle (recover and reuse) SF 6.To establish a maintenance program for equipment with a goal of reducing emissions. To implement a strategy for replacement of SF 6 equipment that leaks to such an extent that leakage cannot be controlled through normal maintenance procedures. To purchase and use equipment that eliminates or reduces the possibility of SF 6 leaks.To promote the development of innovative technologies and information exchange within utility and non-utility sectors to further reduce SF 6 emissions. 2-6.1 NAEC Rev. 39

6.6.3 Training

Only trained and knowledgeable personnel are authorized to handle SF 6 gas and related equipment. Any work performed by outside contractors shall be in accordance with FPLE Seabrook approved procedures. 2-6.3 NAEC Rev. 39 Figure 2-6-1 FPLE Seabrook Environmental Policy Statement SF 6 Management Overview In support of FPLE Seabrook's commitment to pollution prevention and protecting the environment, Seabrook Station adopts the following policy to address the issue of global warming. FPLE Seabrook has entered a voluntary partnership with the Environmental Protection Agency, along with many other members of the utility and industrial community, in an effort to reduce emissions of sulfur hexafluoride, which contribute to this condition. In keeping with the corporate objectives outlined under this policy, FPLE Seabrook will implement appropriate actions to reduce emissions contributing to global warming.Policy Statement FPLE Seabrook will develop, adopt and implement appropriate programs and standards to minimize any contribution to the effects of global warming. Sulfur hexafluoride gas is used extensively in Seabrook Station's electrical distribution equipment, and due to its high global warming potential (GWP) of 22,000 times that of carbon dioxide, it is prudent that emissions be kept as low as reasonably achievable. Programs will be implemented to accomplish the following objectives to the degree technically and economically feasible:* To recycle (recover and reuse) SF 6.* To establish a maintenance program for equipment with a goal of reducing emissions.

• To implement a strategy for replacement of SF 6 equipment that leaks to such an extent that leakage cannot be controlled through normal maintenance procedures.
• To purchase and use equipment that eliminates or reduces the possibility of SF 6 leaks." To promote the development of innovative technologies and information exchange within utility and non-utility sectors to further reduce SF 6 emissions.

This policy supports the corporate objective of minimizing pollution and is implemented in voluntary cooperation with federal and state regulatory agencies.(signature on file)Mark E. Warner Site Vice President 2-6.4 NAEC Rev. 39 7.0

1.6 Overview

The Resource Conservation and Recovery Act (RCRA) is the primary statute governing the regulation of solid and hazardous waste. It completely replaced the Solid Waste Disposal Act of 1965 and supplemented the Resource Recovery Act of 1970; RCRA itself was substantially amended by the Hazardous and Solid Waste Amendments of 1984 (HSWA).The principal objectives of RCRA are as follows: to promote the protection of human health and the environment from potential effects of improper solid and hazardous waste management to conserve material and energy resources through waste recycling and recovery* to reduce or eliminate the generation of hazardous waste as expeditiously as possible In order to achieve these objectives, RCRA authorizes the Environmental Protection Agency (EPA) to regulate the generation, treatment, storage, transportation, and disposal of hazardous wastes. The EPA has set forth these regulations in 40 CFR Parts 260 through 272. The core of the RCRA regulations establishes the "cradle to grave" hazardous waste regulatory program through the major sets of regulations described below. The EPA has delegated the responsibility of managing the State of New Hampshire hazardous waste program to the New Hampshire Department of Environmental Services Waste Management Division.NextEra Energy Seabrook is classified as a Large Quantity generator of hazardous waste in the State of New Hampshire as the waste generation rate is greater than 1000 kg of hazardous waste in any given calendar month. NextEra Energy Seabrook is required to meet all training, reporting, recordkeeping, accumulation, storage, and manifesting requirements under the hazardous waste regulations for large quantity generators.

1.7 General

Requirements

1.7.1 Waste

Minimization

1. Waste Minimization Program Section 3002 (b) of the Resource Conservation and Recovery Act requires generators of hazardous waste to certify on their hazardous waste manifests that they have a waste minimization program in place. A waste minimization program should establish source reduction or elimination as a priority over the management of wastes after they are generated.

This strategy reduces or eliminates the generation of environmentally harmful pollutants, which may be released to the air, land, surface water or ground water. Whenever pollutants cannot be prevented, they should be recycled in an environmentally safe manner. Pollutants that cannot be prevented or recycled should be treated in an environmentally safe manner, with the last resort being disposal or otherwise release to the environment. 3-1.5 NAEC Rev. 40 The EPA's "Guidance to Hazardous Waste Generators on the Elements of a Waste Minimization Program," Federal Register, March 28, 1993, recommends that a waste minimization program should incorporate the following basic elements: a. Top management support b. Characterization of waste generation and waste management costs c. Periodic waste minimization assessments

d. Appropriate cost allocation

e. Encouragement of technology transfer f. Program implementation and evaluation

2. Top Management Support Top management support is necessary for the success of an organization's waste minimization effort.Seabrook Station's Executive Management sets forth the expectations and priorities for the conduct of work at Seabrook Station in the Strategic Business Plans.3. Characterization Identification is the first step in properly managing wastes at any facility.

The waste must first be classified as a solid waste. It must then bedetermined if the waste meets the definition of a hazardous waste. An accounting system to track the types and amounts of waste generated is a necessary component in any waste minimization program.Seabrook Station currently tracks and measures all hazardous and radioactive waste generation. Future enhancements in waste tracking will facilitate meeting this element of the waste minimization program and allow for the tracking of all waste streams.4. Waste Minimization Assessments Waste minimization assessments identify the sources of waste and identify altermative management practices. Waste stream measurements and assessments are performed in order to identify and prioritize Waste minimization opportunities. Based on hazards, costs, and liabilities, each waste stream is prioritized for review and options for management identified. The assessment includes technical feasibility of alternatives, costs, effectiveness, and regulatory burden.3-1.6 NAEC Rev. 40

5. Cost Allocation Cost allocation is necessary to identify opportunities for waste minimization and cost saving opportunities.

The cost of waste generation and management should be directly attributed to the activity responsible for generating the waste.Future enhancements in waste tracking will facilitate meeting this element of the program.6. Encouragement of technology transfer Seeking and exchanging of technical information on waste minimization is encouraged and may be accomplished through benchmarking activities and association with trade or professional organizations.

7. Program implementation and evaluation Seabrook Station's waste minimization program focuses on source reduction and recycling.

Waste streams are reviewed to determine if they can be reduced or eliminated. Waste streams include solid, hazardous, and radioactive waste and discharges to land, air and water.Seabrook station implements and evaluates the waste minimization program through a variety of programs and employee training.a. The Non-Radiological Environmental Impact Review Program requires changes to the plant design and other site-wide activities to be assessed for environmental impacts including the use of chemicals, discharges to water, and discharges to air.b. Expendable Products Control Program establishes the controls necessary, to protect station systems, structures, and components from damage due to improper application of chemical or expendable products. The program also imposes sufficient controls for personnel protection and waste minimization. The potential for the generation of a hazardous waste is reviewed and alternative products are recommended when appropriate.

c. The Station Spill Prevention Control and Countermeasure (SPCC) Plan in conjunction with Spill Response Procedure ON1244.01 provides for the prevention and minimization of pollution to the environment.

d. The Storm Water Pollution Prevention Plan (SWPPP) identifies the potential storm water pollution sources on site and describes best management practices to prevent or minimize the potential for storm water pollution.

e. Seabrook Station recycles solid waste as described in Environmental Compliance Manual (NAEC), Chapter 3.3-1.7 NAEC Rev. 40 General Employee Training for all employees includes waste minimization, chemical use, and expendable product control. In addition, all NextEra Energy Seabrook employees have received Environmental Impact and Awareness Training.g. Radiation Worker Training for all employees who access the radiologically controlled area includes requirements and guidance for minimizing radioactive waste.h. Performance Indicators are used to track the status of various elements of the waste minimization program.Periodic assessments of waste minimization are scheduled and performed in accordance with the fleet procedure on self-assessments.

1.7.2 Waste

Identification Identification is the first step in properly managing wastes at this facility. The waste must first be classified as a solid waste. It must then be determined if the waste meets the definition of a hazardous waste. Any personnel who generate a waste must be aware of the proper disposal technique for that waste, namely the right place to put it for disposal.If any doubt exists about the proper identification and disposal methods, contact the Facilities and Site Support Manager for solid waste or the Hazardous Waste Coordinator for hazardous waste.1.7.3 Waste Stream Measurements and Assessments Waste stream measurements and assessments can be performed in order to identify and prioritize waste minimization opportunities.

1.7.4 Waste

Recycling When practical and consistent with regulatory requirements and economic factors, wastes shall be recycled.1.8 Specific Requirements

1.8.1 Hazardous

Waste 1. Identification and Listing of Regulated Hazardous Wastes (Part 261)Determining that a solid waste is a RCRA hazardous waste is the first step in ascertaining one's responsibility under RCRA. Hazardous wastes may be listed in the regulations by name, by specific processes, or by their characteristics of ignitablity, corrosivity, reactivity, or toxicity. The Hazardous WasteCoordinator is available to provide assistance in determining if any questionable solid waste is a hazardous waste.3-1.8 NAEC Rev. 40

2. Standards for Generators of Hazardous Wastes (Part 262)RCRA places the most accountability and liability for the proper disposition of hazardous waste on the generator.

Generator standards ensure proper recordkeeping and reporting, proper treatment and storage, the use of the Uniform Hazardous Waste Manifest System to track shipments of hazardous waste; the use of proper labels and containers; and the delivery of the waste to a permitted treatment, storage, or disposal facility (TSDF). The following instructions are used to ensure proper disposition:

a. Waste Classification and Labeling (Hazardous Waste Department Instruction HWO 1)Hazardous waste as well as nonhazardous waste and unidentified waste will be classified and labeled in accordance with Hazardous Waste Department Instruction HWO 1.Waste will be classified as hazardous, nonhazardous, or unknown prior to storage or disposal.

Once waste is classified, the waste shall be labeled, stored and processed for disposal. Hazardous and unknown wastes shall be shipped off site within a 90 day time limit.b. Hazardous Waste Storage and Inventory (Hazardous Waste Department Instruction HW02)Hazardous waste generated on site may be accumulated at designated satellite storage locations that have been preapproved by the site Hazardous Waste Coordinator. Accumulation of hazardous waste at these locations is limited to no more than 55 gallons of hazardous waste or 1 quart of acutely hazardous waste as designated in 40 CFR 261.33(e). This limit applies to the TOTAL of all waste at the satellite location.Generators are NOT allowed to accumulate 55 gallons of each waste.Satellite storage locations must be at or near the point of waste generation and under control of the operator of the process generating the waste.Containers must be maintained in good condition/not leaking, must be compatible with the waste stored, and must be kept closed except when necessary to add or remove waste. Containers at satellite locations must be labeled as "Hazardous Waste," the contents of the container identified, and be dated at the start of waste accumulation. The Hazardous Waste Coordinator has the responsibility for the designation and monthly inspection of satellite storage locations. Approved onsite satellite locations are identified in the Expendable Products Control Manual, Chapter 5. Emergency response is coordinated through the Control Room and the Emergency Coordinators phone numbers are documented in ON1244.01, Oil/Chemical Spill.3-1.9 NAEC Rev. 40 Only containers of capacities less than .46 m 3 (119 gal.) that meet DOT requirements for packaging hazardous waste for transport in accordance with 49 CFR 178 will be used for onsite accumulation aMtd-storage of hazardous waste. Use of larger capacity containers, or containers not meeting DOT requirements will necessitate implementation of additional air emission controls, inspection and monitoring requirements under 40 CFR 265.1087.Hazardous wastes are stored for a maximum of 90 days after the start of the waste accumulation date. The 90-day time limit begins when the material is declared a waste by the collector and transferred to the Hazardous Waste Facility.3. Standards for Packaging of Hazardous Wastes (Part 263)The transportation of hazardous waste is regulated by the U.S. Department of Transportation (DOT), as well as RCRA. Wastes are processed for off site disposal in accordance with Hazardous Waste Department Instruction HW03.Processing includes locating the proper processing drum, placing the date of entry on the process drum, proper drum labeling, and disposal of the empty waste container. Hazardous wastes are shipped off site in accordance with Hazardous Waste Department Instruction HW04. Hazardous waste are packaged, labeled, marked, placarded, manifested and contracted carriers documented prior to offsite shipment.4. Recordkeeping and Reporting Requirements Env-Wm 512 Federal and State Hazardous waste regulations require that large quantity generators of hazardous waste maintain certain records regarding their management of hazardous waste.These records include the following:

• Manifest Records- Generator's copy of manifest with transporter's signature and confirmation copy of manifest with TSDF's signature* Records of any test results, waste analyses, or other waste determinations a Copies of Land Disposal Restriction notifications/certifications a Exception reports for non-returned manifest confirmation copies* Personnel training records Quarterly Hazardous Waste Activity Reports* Records of any hazardous waste spills or discharges Records must be maintained on site for a period of 3 years.3-1.10 NAEC Rev. 40 All generators of hazardous waste must notify NHDES Waste Management Division of all hazardous waste activities governed by the regulations.

Notification is done by completing the Notification of Hazardous Waste Activity Form, obtained from the division. Subsequent notification must be made using the same form within 30 days of the effective date of any change in the information originally supplied.When shipping a hazardous waste off site, the generator shall prepare an 8 part prenumbered EPA/DOT uniform hazardous waste manifest, preferably obtained from the destination state. The generator shall retain 1 copy, give 5 to the transporter, and shall-forward 1 copy to the destination state and 1 copy to the division within 5 days of shipment. If the destination's states manifest does not have 8 parts, the generator shall ensure that 8 copies are available for distribution. The following routine reports are required to be submitted to the NHDES -Waste Management:

• Hazardous Waste Quarterly Activity Reports Additional reports* Exception reports for the failure to receive a delivery confirmation copy of the waste manifest are required to be submitted to the division within 45 days.* The generator shall report all manifest discrepancies to NHDES.5. Management of Specific Hazardous Wastes Specific recycling activities addressed in the hazardous waste regulations include reuse, fuels blending, used in a manner constituting disposal, reclamation of lead-acid batteries, and used oil burned for energy recovery.a. Waste Recycling Management will implement sound recycling of wastes whenever practical, balancing regulatory requirements, economic factors and environmental stewardship.

b. Used Oil Management Management of site used oil will be in accordance with HW05. Seabrook Station burns specification used oil in. oil-fired furnaces to provide heat to certain facilities located on site.3-1.11 NAEC Rev. 40

c. Handling and Disposition of Used Batteries Batteries will be collected and stored at the Hazardous Waste Facility.Prior to collection, the batteries will be visually inspected for holes, cracks, or any signs of leaks. Batteries may be sent for reclamation, recycled, or processed as hazardous waste. Generators who store spent lead-acid batteries destined for reclamation shall store the batteries in a manner designed to ensure that the battery housings do not break or leak acid onto the soil or into any groundwaters or surface waters, but shall not otherwise be subject to the hazardous waste rules. Other types of batteries may be subject to the Universal Hazardous Wastes rules.1.8.2 Universal Waste 1. Batteries Universal Waste batteries under the NHDES policy include nickel-cadmium, small sealed lead acid, and hazardous lithium batteries.

Lead-acid motor vehicle batteries are not included under this policy. Universal Waste batteries shall be managed in accordance with the Universal Waste Rules ensuring that the waste is appropriately stored, labeled, and shipped.2. Fluorescent Light Bulbs Used fluorescent light bulbs are recycled by a certified recycler. When removed from service, used fluorescent light bulbs shall be collected in designated containers for collection and recycling. Broken fluorescent light bulbs shall be disposed of as hazardous waste.1.8.3 Elementary Neutralization Limited Permits An Elementary Neutralization Limited Permit is granted to a facility in the State of New Hampshire for a neutralization unit that is used for neutralizing wastes that are hazardous only because they exhibit the corrosivity characteristic and discharges into a surface water in accordance with a National Pollutant Discharge Elimination System Permit. This permit is granted per New Hampshire Waste Regulations Env-Wm 353.04.NextEra Energy Seabrook has applied for and received two separate elementary neutralization permits, one for the treatment and discharge of laboratory wastes that exhibit the corrosivity characteristic and a second for the treatment and discharge-of the Steam Generator Blowdown Waste Holdup Sump. Copies of the neutralization permits are included in Appendix F.Licensing maintains the documentation required for compliance with the permits.3-1.12 NAEC Rev. 40

1.8.4 Mixed

Waste Mixed waste is a subset of hazardous waste and must meet the labeling, storage, recordkeeping, and other management requirements set forth by the Environmental Protection Agency (EPA) for hazardous waste and the NRC requirements for the handling of Low Level Radioactive Waste (LLRW).Mixed waste is identified in accordance with procedure JD0999.914, Handling of Used Chemicals in the RCA. Once identified, the mixed waste is stored in the RCA satellite storage area. The storage area, the storage containers, and the handling of these storage containers shall meet all of the requirements for hazardous Waste.Mixed waste in excess of 55 gallons shall be sent off site within 90 days of when the excess began accumulating. If the radioactive component of mixed waste decays to the point that it meets the free release criteria established by Health Physics procedures, the waste is no longer mixed waste and shall be treated strictly as hazardous waste. It shall then be removed from the mixed waste storage location and shipped to a treatment or disposal facility within 90 days of such determination. The Hazardous Waste Coordinator reviews mixed waste generation on a case-by-case basis to determine if the Station should apply for a regulatory exemption from the hazardous waste regulations. An exemption would normally be applied for when treatment for mixed waste is not available or when it is economically beneficial to accumulate a larger amount of waste.1.8.5 Solid Waste NextEra Energy Seabrook attempts to recycle as much waste as practical. The following waste streams are identified and will be maintained segregated from other wastes for ease of collection, processing, and recycling. Waste materials shall be placed within the proper designated containers. Waste materials shall not be placed on the ground. Disposal of wastes other than those generated at Seabrook Station is prohibited.

1. Automobile Tires Waste tires shall be disposed of only in a permitted facility after being treated in a manner that will preclude creeping, such as shredding, filling, splitting or quartering, unless the facility has technology capable of using whole tires in their processing.

Waste tires are removed from site by an authorized contract disposal company. Tires are stored on site on a temporary basis only.3-1.13 NAEC Rev. 40

2. Scrap Metal (Copper, Iron, Steel, Aluminum)a. Scrap shall, be collected in a designated container at the Transfer Facility adjacent to the Carpenter Shop. Scrap metal is removed from site by a scrap metal dealer, sorted, and then recycled.b. These waste streams shall be kept segregated from other waste streams.3.

2.0 TRANSPORTING

DEPARTMENT OF TRANSPORTATION (DOT) HAZARDOUS MATERIALS 2.1 Purpose, This section provides regulatory interpretations, and provides detailed requirements to meet Department of Transportation (DOT) requirements for shipping DOT hazardous materials common to FPLE Seabrook.This section also establishes guidelines and responsibilities for FPLE Seabrook personnel involved in the transportation of nonradioactive hazardous materials on public roadways. This section also addresses the laws governing transportation of hazardous materials and the reporting of accidents involving hazardous materials as stated in Title 49, U.S. Code of Federal Regulations (CFR), Parts 100 through 200.NOTE There are distinct differences between hazardous materials and hazardous waste.If a material. is waste, contact the Hazardous Waste Coordinator as there are specific state and federal rules and regulations (Title 40, Code of Federal Regulations, Part 260 [40 CFR 260]) which pertain to hazardous waste. Some hazardous materials may become hazardous wastes. All hazardous wastes are hazardous materials. Many materials commonly shipped may not appear to be hazardous, but are classified as hazardous materials by the DOT. For example, certain paints are flammable and are classified as hazardous materials by the DOT A DOT hazardous material meets two criteria 1. it poses an unreasonable risk when transported in commerce, and 2. the DOT has designated it a hazardous material.DOT hazardous materials are listed alphabetically, by proper shipping name in DOT regulation 49 CFR 172.101.2.2 Applicability These environmental requirements apply to the transportation of all materials classified as hazardous materials by the DOT on public roadways.Federal DOT hazardous materials regulations apply to all intrastate and interstate transportation in commerce. Transporting hazardous materials on Seabrook Station property does not require shipping papers.Regulations and specific requirements for container types, markings of container types, markings of containers, and placard markings for vehicles are included in 49 CFR 100-200.3-2.1 NAEC Rev. 39

Such shipments are rarely performed at Seabrook Station. The thresholds for such shipments are delineated in GN1332.02 and the referenced Nuclear Regulatory Commission Orders. The thresholds are also specified in the Seabrook Station procedures for shipment of radioactive and nonradioactive hazardous materials. Shipments of RAMQC or high risk nonradioactive hazardous materials are prohibited until such time that all ASMs have been implemented and requisite notifications performed as specified in GN1332.02.

2.7 Hazardous

Materials Certificate of Registration A copy of the FPLE Seabrook Energy Certificate of Registration is kept on file by Licensing and Records Management at Seabrook Station.3-2.5 NAEC Rev. 39

2.8 Requirements

The following outlines the process requirements which must be completed to ensure compliance in completing hazardous material shipping papers. These requirements are generally sufficient to determine DOT requirements to prepare the necessary documentation for day-to-day operations.

2.8.1 Hazardous

Materials Transportation Requirements I1. General Before any hazardous materials may be transported in commerce on public roads, the following steps must be taken by the person transporting or preparing the shipment to ensure compliance with the law: a. Determine if the material is a hazardous material. A DOT hazardous material is capable of posing an unreasonable risk to health, safety, or property.To determine if the material is a DOT hazardous material, review the product's Material Safety Data Sheet (MSDS), if available, review the DOT definitions for hazardous materials (see Figure 3-2-1) and read the product label (words such as flammable, corrosive, or poison indicate that the material may be DOT regulated). If employees have reason to suspect that the material may be a DOT hazardous materialand they require additional shipping information, they should contact the Hazardous Waste Coordinator or Licensing for assistance.

b. If the material is a DOT hazardous material, determine the proper DOT shipping description.

c. Prepare shipping papers.d. Select/use appropriate container marking and label(s).e. Select the appropriate package.f. Determine if vehicle placards are required.

If so, affix placards to the appropriate sized (GVWR) vehicle for the load. Contact the Transportation Department if additional information is required.2. Employee Training The DOT requires employees who handle, load, store, and transport DOT hazardous materials to be trained. Recurrent training must be implemented at least every 36 months.DOT General Awareness Training is required for all hazardous material employees. DOT Safety Training is required for'all hazardous material employees who handle hazardous materials. 3-2.6 NAEC Rev. 39 Vehicle operators must receive DOT hazardous material training before they operate a vehicle transporting DOT hazardous materials. The regulations also require that new hazardous material employees complete training within 90 days of employment. Employees who change job functions must be trained in. the new job functions within 90 days after the change.Specific hazardous materials-training requirements for site personnel are included in the Hazardous Materials Training Program Description.

2.8.2 Proper

Shipping Name Selections I1. Basic Description The basic description of hazardous materials on shipping papers must include the following:

a. Proper DOT shipping name b. Hazard class or division c. Identification number (UN or NA number)d. Packaging group 2. Proper DOT shipping name Refer to the 49 CFR 172.101 Hazardous Materials Table to determine the proper DOT Shipping Name using the following directions:

a. Look up the technical name of the material.

The technical name is the"common name of the material" (e.g., Gasoline);

b. Determine the chemical family of the material (e.g., Alcohols, not otherwise specified

[N.O.S]);c. Determine whether the end use of the material is listed (e.g., compounds, cleaning liquid);d. Look up the hazard class of the material (e.g., corrosive liquids, N.O.S.);e. Determine whether the material is a CERCLA (Superfund) hazardous substance (e.g., asbestos or PCBs). Refer to 49 CFR 172.101, Appendix A.f. Determine whether the material is a Marine Pollutant. Refer to 49 CFR 172.101, Appendix B..3-2.7 NAEC Rev. 39 NOTE Do not use the DOT Emergency Response Guidebook (ERG) to determine the DOT description for hazardous materials. The names provided in the ERG are not proper DOT shipping names.3. Description to Include Weight The total number of compressed gas cylinders or the total weight or volume for each hazardous material must be included on the shipping paper.4.. Description to Include UN/NA Identification Numbers The UN/NA number is the third component of the proper shipping description. The identification number is four-digit number which used by emergency response people to identify the material rather than using an often complex proper shipping name.5. Description to Include Packing Group The Packing Group is the fourth component of the proper shipping description. The packing group is an indication of the degree of danger presented by the hazardous material. The three packing groups are as follows:* Packing Group I (PG D) materials have great danger* Packing Group II (PG II) materials have moderate danger* Packing Group III (PG III) materials have minor danger Packing group designations are required for Class 3 (Flammable Liquids); Class 4 (Flammable Solids); Class 5 (Organic Peroxide); Class 6 (Poisonous/Infectious); and Class 9 (Miscellaneous). Packing group designations do not exist for Class 2 (Flammable and Nonflammable Gases), Class 7 (Radioactive), ORM-D or combustible materials. When the DOT provides more than one packing group for a material, the packing group for a specific material will be determined by physical characteristics of the material (e.g., flash point, boiling point, vapor pressure).

6. Consumer Commodity (ORM-D)Any DOT hazardous material which presents a limited hazard during transport due to its form, quantity, or package may be reclassified as a Consumer Commodity (ORM-D). Typical materials within FPLE Seabrook which can be shipped as ORM-Ds include most aerosol products such as paint, cleaners, power cartridge devices, and small containers of flammable liquids.3-2.8 NAEC Rev. 39 The following materials may not be transported as Consumer Commodities (ORM-D): a. Flammable compressed gases such as butane, propane, and MAP gas cannot be shipped as ORM-D regardless of the container size. This applies when a flammable compressed-gas is theprimary product (not a propellant for a powder, paste, gel, or liquid). Materials common to FPLE Seabrook include soldering or brazing torches. When transported on public roads (while in commerce), these flammable gas cylinders must meet all DOT requirements including use of a DOT-approved container, DOT container marking/labeling, DOT shipping paper, and, as necessary, placarding of the vehicle (Fed. Reg. 10/28/91, Vol. 56, #208).b. Industrial/commercial hazardous materials which are not packaged in a form intended for home use may not be classified as an ORM-D. This includes materials intended for use only by a professional (e.g., weed killer sold only to professional crop dusters), containers of materials used to manufacture other materials, materials used in an industrial process, and chemicals used for scientific/

chemical laboratory purposes (i.e., chemicals which are not available at a retail store).In order to be shipped as an ORM-D, the material must be packaged and distributed in a form suitable for sale at a retail agent/store for personal or household use/care. The DOT has determined what packages can be reclassed as ORM-D materials for all nine DOT hazard classes. See the table below for a list of materials and the amounts not to be exceeded in an individual package if the material is allowed to be transported as ORM-Ds.When transporting DOT hazardous materials classified as "Consumer Commodities" or "ORM-D," ensure that they are placed in a securely closeable box (e.g., a tool box, ammunition box) or a compartment on the vehicle with a latched door. If the vehicle has compartments accessed from the outside of the vehicle, the ORM-D materials must be enclosed in an inner package or compartment (i.e., a door behind a door). The vehicle may have more than one ORM-D container. The total weight of the ORM-Ds in a single package must not weigh more than 65 lbs. (inclusive of package and contents). 3-2.9 NAEC Rev. 39 Amounts Not to be Exceeded in Packages to be Classed as Limited Quantity or Consumer Commodities ORM-D: Other Regulated Material -Consumer Commodity Hazard Class Class/ Packing Limited Quantity Consumer Division Group Commodities Flammable Class 3 PG I 16 ounces (0.5 L) Same Liquids PG II 0.3 gallons (1.0 L) Same PG III 1 gallon (5.0 L) Same Same Flammable Division PG II 2.2 lbs. (1.0 kg) Same Solids 4.1 PG III 11 lbs. (5.0 kg) Same Corrosive Class 8 PG II 0.3 gallons (1.0 L), liquids Same Materials 2.2 lbs. (1.0 kg), solids PG III 1 gallon (4.0 L), liquids Same 11 lbs. (5.0 kg), solids Poisonous Division PG III 1 gallon (4.0 L), liquids 8 oz. (250 ml.)Materials 6.1 11 pounds (5.0 kg), solids 8.8 oz. (250 g)Oxidizers Division PG II 0.3 gallons (1.0 L), liquids Same 5.1 PG III 1 gallon (4.0 L), liquids Same Organic Division PG I 1.0 oz. (30 ml), liquids Same Peroxides 5.2 PG II Same PG III Same Miscellaneous Class 9 1 gallon (4.0 L), liquids Same 11 lbs. (5.0 kg), solids Same Flammable Gas Class 2.1 Cannot be a Limited Quantity Cannot be an ORM-D Nonflammable Class 2.2 4 fluid oz. (7.22 cubic inch) Same Compressed Gases Aerosols 27.7 fluid oz. (50 cubic inch) Same charged with nonpoisonous solutions 3-2.10 NAEC Rev. 39

7. Limited Quantity The DOT regulations have provisions allowing the transport of those materials which cannot be classified as an ORM-D (as discussed above) without meeting all the DOT requirements.

This exception is called the '.'Limited Quantity." Each hazard class has specific "Limited Quantity" requirements which are listed above (see §2.8.2.6, Consumer Commodity). Shipping a material as a Limited Quantity allows one to use a non-DOT approved container. However, the package must be marked with the DOT shipping name (UN/NA numbers are not required). Additionally, no DOT labels nor DOT placards are to be used. A DOT shipping paper must be used and must include the letters "LTD QTY" after the proper DOT shipping name.For example: a one-quart metal container of xylene which is distributed as an industrial cleaner (for industrial use only) can be shipped as a Limited Quantity.The container used does'not need to meet the DOT package requirements other than it must be a good package. To properly ship'this material, one would need to mark the container with the proper DOT shipping name (no UN/NA number required). A shipping paper would need to be used. An example of the shipping paper description is: "Xylenes, LTD QTY, 3, UN1307, PG II" NOTE Certain materials such as nitric acid, propanol, and methanol cannot be shipped as "Limited Quantities" or "Consumer Commodities." 2.8.3 Shipping Papers NOTE Hazardous material shipments are prohibited in the company express mail system.I1. FPLE Seabrook Shipments When DOT hazardous materials are transported on a company vehicle, they must be readily identified on a shipping paper. If the material is a hazardous waste, a waste manifest (which is a type of shipping paper) must be used. It is the responsibility of the vehicle operator to ensure that proper shipping papers are used while transporting DOT hazardous materials. Once the materials have been removed from the vehicle, the shipping paper must be modified (e.g., rewritten, line crossed out) to reflect the materials on the vehicle. Once the shipment is completed, the shipping paper can be discarded. 3-2.11 NAEC Rev. 39 The FPLE Seabrook Hazardous Materials Shipping Paper (NAEC FORM 3-2A)lists the common materials found at FPLE Seabrook. It has been designed to provide the user with details for meeting most DOT requirements including the marking and labeling of packages, and placarding of vehicles. This shipping paper is for use on FPLE Seabrook vehicles only.Items not already listed on the shipping paper must be entered on the shipping paper by the shipper. Abbreviations are prohibited except for package type, quantity, or volume. For information concerning materials not listed on the form, see 49 CFR Table 172.101.The Hazardous Material Shipping paper does not include a certification statement as this is not required when the materials are transported on a FPLE Seabrook vehicle.2. Vendor or Contracted Carrier Shipping Papers If the hazardous material is to be shipped by a contracted carrier or non-FPLE Seabrook vehicle, the hazardous materials employee who prepared the shipment (marking/labeling/packaging/completing shipping papers) must use/sign the certifying statement as stated below: "This is to certify that the above-named materials are properly classified, described, packaged, marked, and labeled and are in proper condition for transportation according to the applicable regulations of the Department of Transportation." The Straight Bill of Lading form includes this statement. The Hazardous Materials Shipping Paper (NAEC FORM 3-2A) does not include the statement and may not be used by a contracted carrier or non-FPLE Seabrook vehicle.3. Special Carriers -DOT Hazardous Material and the United States Mail or Parcel Services. The U.S. Postal Service, United Parcel Service or Federal Express should be contacted for specific requirements for shipping hazardous material.4. Required Shipping Paper Information When filling out shippifig papers, the shipper shall include the following information:

a. The proper DOT Shipping Name as it appears in 49 CFR 172.101, Hazardous Materials Table.b. The Hazard Class number.c. The Identification Number assigned to the material.d. The Packing Group assigned to the material.

Packing Group designations do not exist for Class 2 (Flammable/ Nonflammable Gases), Class 7 (Radioactive), ORM-D, or combustible materials. 3-2.12 NAEC Rev. 39

e. The total quantity by weight or volume or the number of compressed gas cylinders.

Abbreviations such as "lbs." for pounds and "gal." for gallon are allowed.5. Additional Entries on Shipping Papers a. Limited Quantity If a hazardous material is shipped as a limited quantity, the words"Limited Quantity" or the abbreviations "LTD QTY" must be on the shipping paper following the basic descriptions.

b. Dangerous When Wet Materials The words "Dangerous When Wet" shall be entered on the shipping paper as part of the proper DOT Shipping Name when a material is classified "Dangerous When Wet." c. Technical Names for "N.O.S." Descriptions The technical name of the hazardous material must be entered in parentheses in association with the shipping name when the Proper Shipping Name includes the "N.O.S." (not otherwise specified or listed in the DOT regulations) description.

An example would be "Hazardous waste, liquid, N.O.S. (xylene and ethanol mixture)." d. Hazardous Substances -RQ Hazardous substances (in excess of the Reportable Quantity) must have as part of the proper shipping name, the letters "RQ" before the proper name.Example: RQ, Environmentally Hazardous Substance, Solid, N.O.S.(Asbestos).

6. Key Points to Remember for Shipping Papers The shipping paper tells the driver about the hazardous material on his/her vehicle and provides vital information to emergency fesponders in the event of a DOT incident.

The shipping paper must be readily available at all times during the transport of hazardous materials and must be a. within reach of the driver while restrained by the seat belt, b. readily visible or in a pouch on the door, or c. on the driver's seat, and d. easily identifiable wvhen carried with other papers by tabbing them or keeping on top of other paperwork. 3-2.13 NAEC Rev. 39'

7. Hazardous Material Emergency Response Information The Seabrook Station Control Room serves as the 24-hour contact point to handle emergency responses.

NAEC FORM 3-2B, Hazardous Material Emergency Response Information (49 CFR 171.15,-171.16), shall be completed for each hazardous material shipment or a Straight Bill of Lading form via a common carrier and any shipments made using a special carrier (UPS, FEDEX, etc.). The completed form must be delivered or faxed to the Control Room Shift Manager prior to the shipment's leaving Seabrook Station property.8. Record Retention Hazardous Material Shipping Papers shall be retained for a minimum of 375 days.2.8.4 DOT Labels Hazardous material shipments are identified by standard (preprinted 4" x 4") warning labels placed on containers. DOT labels provide quick and easy identification of hazards present. DOT hazardous materials are generally received from manufacturers or distributors with DOT labels affixed. Hazardous material employees are responsible for ensuring DOT labels are affixed to packages prior to shipping and/or before transportation on FPLE Seabrook vehicles. Refer to DOT regulations 49 CFR 172 to 180 for furtherinformation on DOT labels.NOTE DOT labels cannot be "hand-made." DOT labels must meet specific color and durability criteria.As a result of recent changes in the regulations, the DOT labels have changed. DOT labels must now display the hazard class or division number within the lower point of the label.1. Selecting Labels Labeling instructions for commonly shipped hazardous materials are detailed on the FPLE Seabrook Hazardous Materials Shipping Paper (NAEC FORM 3-2A).Labels are obtained by contacting hazardous materials employees at Warehouse 2 receiving area.2. Label Placement a. Labels must be affixed to the exterior of a package. If an exterior package is used to contain an inner package of hazardous materials, the exterior package must be labeled.b. A tag holding the DOT label may be used if a package is so small that a label will not fit on it or the package is of an irregular surface such that the label will not stick.3-2.14 NAEC Rev. 39

c. Labels must be near the marking (see §2.8.5 for DOT marking).d. Labels must represent the hazard in the package. If the material in a package has more than one hazard classification, the package must be labeled for each hazard.e. When two or more materials of different classes are in the. same package, multiple labels may be required and are placed next to each other.f. Labels are not required on Limited Quantity or ORM-D Packages.(See §2.8.5 for ORM-D mark except Class 6 [Poisons].)

3. Subsidiary Hazard Labels Certain DOT hazardous materials have more than one hazard class. For these materials, the package shall be labeled with primary and subsidiary hazard labels.The hazard class/division number must be displayed in the lower point of the primary hazard label and must not be displayed on the subsidiary label. The shipping profiles will specify which labels to use for common FPLE Seabrook materials.

Ensure that the specific labels are used as directed in the profile sheet.NOTE Labels shall not be altered in any manner. Do not cross out or otherwise eradicate the hazard class on a DOT label.4. Empty Containers and Labels A package which has been "emptied" but not purged of the hazardous material is still regulated by the DOT, e.g., a safety can which previously held gasoline and now contains gasoline vapors. This container is still DOT regulated and must remain labeled as if it were full.The same markings and labels are used on a container with residual hazardous materials as the full container. However, the DOT shipping paper should include the following additional description: "Residue: Last Contained..." in association with the basic DOT description. For example, FPLE Seabrook may receive returnable DOT-approved "Totes" containing materials such as Hydrazine or Sodium Hypochlorite. When these containers are shipped back to the vendor, the shipping paper should contain the above description.

5. Authorized Label Modifications For a package containing Oxygen, the word "Oxygen" maybe used on the Oxidizer label in place of the word "Oxidizer," and the class number "2" (nonflammable gas) may be used in place of the class number of"5.1" (Oxidizer).

3-2.15 NAEC Rev. 39 NOTE Labels shall not be physically altered in any manner. Do not cross out or otherwise eradicate the hazard class or print on a DOT label.6. Exceptions from Labeling (see 49 CFR 172.400a)DOT hazard labels are not required on the following:

a. A cylinder containing a Division 2.1 (flammable gas) or Division 2.2 (nonflammable gas) that is (1) not poisonous, (2) carried by a private motor carrier (such as FPLE Seabrook) or contract motor carrier, (3) not overpacked, and (4) durably to legibly marked with compressed gas association labels.b. A compressed gas cylinder permanently mounted in or-on a transport vehicle.c. A portable tank which is already properly placarded.

d. A package (less than 119 gallon capacity) containing a combustible liquid.e. A package containing a material classified as ORM-D (however, it must have the ORM-D marking.f. Certain packages containing "limited quantities" and "small quantities." NOTE Packing labels may be obtained at Warehouse 2.2.8.5 DOT Markings The shipper is responsible for marking each package containing DOT hazardous materials.

All containers must be marked with the proper DOT shipping name and, identification number. There are slightly different requirements for marking bulk packages (greater than 119 gallons capacity) and nonbulk packages (less than 119 gallon capacity).

1. Selection of Marking Marking instructions for commonly transported hazardous materials are detailed on the FPLE Seabrook shipping paper.3-2.16 NAEC Rev. 39

2. Placement of Marking Marking a. must include proper DOT name and ID number.b. must be durable, legible, and written in English.c. may be printed on the package or affixed by tag.d. must be in contrasting colors, unobscured, away from other markings (e.g., trade name).e. must be near the DOT label(s).3. Marking Nonbulk Packages Nonbulk packages have a capacity of less than 119 gallons. The proper shipping name and identification number must be displayed on nonbulk packages.4. N.O.S.Packages containing materials which use the generic "N.O.S." description must be marked with the technical name in conjunction with the generic N.O.S. name. For example: "Hazardous waste, Liquid, N.O.S. (xylene and ethanol mixture) NA 3082." 5. "RQ" If the material is a CERCLA hazardous substance and the package contains the reportable quantity, the letters "RQ" must be marked on the package in'conjunction with the proper shipping name. For example: "RQ, Environmentally Hazardous Substance, solid, N.O.S. (Aldicarb), UN 3077." 6. Marking Package Containing Liquids Inner containers of liquids which are packaged in an outer package must be packed with the closures facing up. The DOT "This End Up" marking must be placed on the package with the arrow pointing upward.7. Packages Containing Poisons Poison liquids and gases which are identified as poisonous by inhalation must be marked with the words "Poisonous By Inhalation" and "Hazard Zone (A or B)" in association with the required DOT label.8. ORM-D -Consumer Commodity Packages containing a Consumer Commodity must be marked with the "ORM-D" mark. No other label or identification number is required on the package. No shipping paper is required to transport ORM-D materials (see §2.8.2.6 for additional details).3-2.17 NAEC Rev. 39

9. Limited Quantity Shipping a material as a Limited Quantity allows one to use a non-DOT-approved container.

However, the package must be marked with the DOT shipping name (UN/NA numbers are not required) (see §2.8.2.7 for additional details).10. Name and Address on Package The name and address of the person or party to whom something is delivered must be on a DOT hazardous material package when it is shipped or transferred from one carrier (common, contract, or private) to the next, transferred from one vehicle to another as part of a full load, or shipped in a portable tank.11. Marking Bulk Packages NOTE As a general rule of thumb, placards must be visible on all four sides of a bulk packaging and at least three inches away from any other markings.a. Tanks Between 119 Gallons and 1000-Gallons Capacity The proper DOT shipping name and identification number must be placed on bulk packages greater than 119 gallons and less than 1000 gallons, such as portable tanks. These markings must be displayed on the two opposing sides of the tank sides. Identification numbers shall not be displayed on radioactive, explosives, dangerous, or subsidiary hazard placards.b. Tanks with Capacity Greater than 1000 Gallons Portable containers with a rated capacity greater than 1000 gallons must have the identification number and shipping names placed on each side and each end of the container.

c. Cargo Tanks Only identification numbers are required on a cargo tank and must be displayed.

If a placard is required, the identification number may be displayed across the center of the placard or on a separate specification orange panel placed next to the placard.d. Empty Bulk Packages Each bulk package must remain marked and/or placarded when it is emptied unless it has been sufficiently cleaned/purged of residue/vapors to remove any potential hazard or been refilled with a compatible material requiring different markings or no markings. Do not use the "Residue Placard" on bulk packages other than rail cars.3-2.18 *NAEC Rev. 39

e. Empty Railroad Tank Cars If a railroad tank car has been emptied and has not been cleaned/purged, it must display the correct "Residue Placard." 2.8.6 Containers and Packages Major changes in packaging standards were instituted in HM-181. Packaging hazardous materials properly is important to ensure safety during transportation and handling.

It is the shipper's responsibility to determine that the material is packaged properly. Drivers and receivers should also check packages in order to prevent spills, leaks, or injury.A hazardous material is assigned to one of three package groups based on its particular safety hazards. PG I, PG II, and PG III indicate that the degree of danger represented by the material is either major (PG 1), moderate (PG II), or minor (PG III). Follow the package group as discussed in each material profile sheet. For example, when transporting flammable paints in the original manufacturer's package, one must determine which package group must be listed on the shipping paper. The package group is based on the material's specific physical properties (e.g., for flammables, this includes the flash point and boiling point of the material). Package groups play a major role in determining the package that is used to transport the material. For this reason, it is best to use the original manufacturer's container when possible, rather than repackage a material.Always use a "good package" when transporting hazardous materials. When selecting a proper DOT package, ensure that the package is clean, closed securely, and compatible with the materials to be shipped. It is best to use the manufacturer's container, rather than repackage a material.All packages containing DOT Hazardous Materials must be designed, constructed, and contents limited, so that under normal transport conditions

• there will be no significant release to the environment, , the effectiveness of the package will not be substantially reduced, and" there will be no mixture of gases, vapors in the package which could spontaneously release heat or pressure, or by explosion reduce the effectiveness of the package.All packages must be strong and tight.Previously, the DOT specified what containers could be used to transport hazardous materials.

These specifications dealt with the construction of the container (e.g., types of materials, number of welds, nails, type of wood, etc.). The new packaging requirements are "performance-based" criteria. A package nfoW must be capable of meeting criteria such as the drop test, leakproof test, stacking, hydrostatic pressure, and vibration test.This change facilitates international commerce and promotes technological advances in packages. The performance-based criteria are nowin place. However, manufacturers have until October 1, 1994, to continue manufacturing containers under the old provisions. By October 1, 1996, former DOT specification packages may no longer be used.

1. Package Identification Codes Each material must be packaged according to its packing group as detailed in 49 CFR 172.101 and Part 173. Packages designed to transport hazardous materials must be marked by the container manufacturer to show compliance with DOT package regulations.

New performance-oriented package markings appear on the package as follows: U 4G H 4/s/89 N USA/+ABOOO1/APSS The UN means the package is manufactured and tested according to international standards. The top line indicates the type of container, construction materials, packing group, maximum gross, solids, or inner package, and the year it was manufactured. The bottom line indicates the country, authorizing mark, DOT-authorized lab tested, and the testing house registration and number.2. Reuse and Reconditioning of Drums HM-181 placed specific restrictions on the reuse of metal and plastic drums.Reuse is based on minimum thickness requirements intended to ensure the container will withstand handling and transport.

a. Metal and Plastic Drums Drums which are reused must conform to the following criteria: (1) Each must be inspected and may not be reused unless free of incompatible residue, rupture, or other damage which reduces its structural integrity.

(2) If drums show evidence of reduction in structural integrity, it must be reconditioned before reuse.(3) If intended to contain liquids, the package must be subject to a leakproofness test, using air at an internal pressure (gauged) of at least 7.0 psi.(4) Any package which is leakproof tested or reconditioned must be marked with the letter "R" and the name and address of the package reconditioner. (5) Metal and plastic drums used as single packaging or the outer package of composite packaging are authorized for reuse only when they are marked (in millimeters) with the thickness of the packaging material andconform to specific criteria (see 49 CFR 173.28).(6) Packaging made of paper, plastic film, or textile are not authorized for reuse (does not include fiberboard). 3-2.21 NAEC Rev. 39

b. Exceptions for Reuse of Drums -Reuse of STCs or NRCs (1) The shipper may determine if a container is a Single Trip Container (STC) and Nonreusable Container (NRC) by looking at the DOT specification markings for the letters "STC" or "NRC." On drums this is usually found on the bottom head of the drum, or on the rim in some cases (e.g., DOT 17E STC).(2) Containers marked as STC or NRC may (a) be reused for materials which are not regulated by the DOT as long as they are in good condition, or (b). be reused if they have been tested and certified for reuse by a DOT-registered drum conditioner.

(3) A package may be reused without being subject to the preceding.under the following conditions: (a) Transportation is by highway only.(b) A package is not offered for transportation less than 24 hours after it is finally closed for transport and each package is inspected for leakage and is found to be free from leaks immediately prior to transport.(c) Each package is loaded by the shipper and unloaded by the person or party to whom it is delivered.(d) The package may be reused only once.3. Salvage and Overpack Drums The requirements for use of salvage drums and overpack are as follows: a. Must be a metal or plastic removable head drum.b. Must be marked and labeled as prescribed for the respective materials (see 49 CFR 173.3).c. Capacity cannot exceed 450 liters (119 gallons).d. When necessary, sufficient cushioning, and packing material shall be provided to prevent excessive movement of damaged inner packages and to capture any leaking liquid.e. Must be marked "Salvage Drum." f. Must be a drum manufactured to meet Packing Group Ell and be marked by the manufacturer as meeting Packing Group mH for a liquid with specific gravity of 1.2 and with a hydrostatic test of 35 Kpa.3 -2.22 NAEC Rev. 39

4. Lab Packs A lab pack may be used under the following conditions:

a. The material(s) to be packed are from the following hazard classes and divisions:

3 Flammable/Combustible Liquids 4.1 Flammable Solids 4.2 Spontaneously Combustible Material 4.3 Dangerous When Wet 5.1 Oxidizer 6.1 Poisonous Materials 8 Corrosive Materials 9 Miscellaneous Hazardous Materials b. Outer packaging must be UN 1A2 or 1B2 metal drums, a UN ID plywood drum, a IG fiber drum or a 1H2 plastic drum.c. Each outer packaging must contain only one hazard class.d. Inner packages containing liquids must have sufficient chemically compatible absorbent material.e. Gross weight must not exceed 205 kg (425 lbs.).5. Empty Packages The DOT defines an empty container as one which has had the hazard removed from the package (i.e., purged of the hazard). Since FPLE Seabrook staff rarely purge containers, it is important to realize that containers which are emptied by normal means (e.g., pouring or pumping) may contain residual amounts of DOT hazardous materials. For example, a gasoline can which has no liquid but contains gasoline vapors is still hazardous. As such, it is regulated by the DOT as if it were full of gasoline thus requiring the use of DOT markings, labels, shipping papers, and perhaps placards while being transported. The same markings and labels are used on a container of residual materials as the full container. Additional information is required on the shipping paper for bulk packages (greater than 119 gals. capacity) with residues of DOT hazardous materials. The'following additional description should be included with the proper DOT name: "Residue: Last Contained..." in association with the basic DOT shipping name of the hazardous material last contained in the package.3-2.23 NAEC Rev. 39

6. ORM-D When transporting Consumer Commodities or "ORM-D," ensure that they are placed in a securely closeable outer package (e.g., strong tool box, ammunition box) or a compartment within a compartment where there is a door behind a door.Vehicles may have more than one ORM-D container.

The total weight of the ORM package (inclusive of outer package and contents) must not be more than 65 lbs. total weight.. ORM-D packages must have the ORM-D marking (see §2.8.2.6 for additional details).7. Other Container Requirements Although most hazardous material containers are specified by the DOT, there are obscure materials which have other container regulations which apply as well.2.8.7 Placards Placards alert people to the potential hazards in a motor vehicle, rail car, freight container, cargo container, or portable tank. They also provide emergency response personnel with important information should an accident occur. Refer to DOT regulations 49 CFR 172 to 180 for further information on DOT placards.1. New Placards The hazard class or division numbers are required on placards. Hazard class numbers must be displayed in the lower comer of the placard corresponding to the primary hazard class or the material. Hazard class numbers are not allowed on a placard that corresponds to a subsidiary hazard. No hazard class number is allowed on the "Dangerous" placard.2. Other Rules Placards a. must be provided by the shipper to the carrier, b. must represent the hazard on the vehicle, c. must be placed on all 4 sides of the vehicle (front placard may be on the power unit or cargo body, however, the placard must be visible), NOTE The adhesive used on most placards is a strong permanent-type adhesive. The vehicle paint may be damaged if placards are attached directly onto painted surfaces. A placard holding frame is available from the Department of Transportation which allows easy removal of placards.d. must be placed in the on point configuration (wording must be read from left to right), 3 -2.24 NAEC Rev. 39

e. must be placed so that they are not obstructed by anything, f. must be placed at least 3 inches from other markings, g. must be located so that dirt and mud will not splash on, and h. must be maintained in readable condition.

3. Placard Determination Prior to shipment, the shipper must determine whether or not vehicle placards are required.

Placarding is required on vehicles depending on the material and quantity of material transported. Typical placards required for commonly shipped FPLE Seabrook hazardous materials are illustrated on the back of the Hazardous Materials Shipping Paper.Placards are obtained by contacting the hazardous materials employees at Warehouse 2 receiving area.4. Materials Which Require No Placards No placards are required for materials classified as follows: a. Radioactive White I (Class 7)b. Radioactive Yellow II (Class 7)c. Infectious Substances (Poison/Division 6.2)d. ORM-D e. Any material identified as a "Limited Quantity" f. Combustible liquid in containers of 119 gallons (450 L) or less, each container g. Miscellaneous Hazardous Materials (Class 9) with no other DOT hazard 5. Placards Required The DOT regulations have two tables for determining whether placards are required.a. Table 1 (49 CFR 172.504)Placards are required for an_ quantity of Table 1 materials which include the following: (1) Explosives in Division 1.1, 1.2, 1.7 (2) Poison Gases (Division 2.3)(3) Dangerous When Wet (Division 4.3)3-2.25 NAEC Rev. 39 (4) Gases which have the Poison Inhalation Hazard (Division 2.3)(5) Radioactive III b. Table 2 (49 CFR 172.504)Placards are required when the combined total weight of a Table 2 hazard class exceeds 1,000 lbs. (including the weight of the package and its contents). Either a "Dangerous" placard or a placard(s) for the specific hazard must be used. However, the preferred method is to placard for each specific hazard(s) on the vehicle. Multiple placards may be placed on each side of the vehicle as long as the hazard is on the vehicle. -Table 2 materials include the following: (1) Explosives Division 1.4, 1.5, and 1.6 (2) Flammable Gases (Division 2.1)(3) Nonflammable Gases (Division 2.2)(4) Flammable Liquids (Class 3)(5) Combustible Liquids in packages with capacity greater than 119 gallons (Class 3)(6) Oxidizers (Division 5.1)(7) Poisons in Package Group other the PG I Inhalation Hazard'(Division 6.1)(8) Keep Away From Food -Poisons (Division 6.1 PG III)(9) Flammable Solids (Division 4.1)(10) Spontaneously Combustible (Division 4.2)(11) Organic Peroxides (Division 5.2)(12) Corrosive Materials (Class 8)6. Mixed Loads When shipping bulk packages (less than 119 gallons capacity) of two or more Table 2 materials, a Dangerous placard may be used in place of the placard required for each hazard class. However, using the Dangerous placard does not represent the hazard as clearly as the specific placards.When 5,000 lbs. of any hazard class from Table 2 is loaded at any one facility, the placard for that hazard class must be displayed. 3-2.26 NAEC Rev. 39

7. Placards and Driver Requirements If a vehicle requires placards, the vehicle operator must have a Commercial Drivers License with a Hazardous Material Endorsement.

Note that as discussed earlier there are certain materials which are exempt from placarding. This exemption also excludes the driver from the hazardous material endorsement. An improperly or insufficiently placarded vehicle may not be moved on public roads except in an emergency. Even if such a an emergency exists, one of the following conditions must be in effect before the vehicle is moved: a. The vehicle must be escorted by a representative of local or state government (e.g., police).b. The U.S. DOT has granted permission to move the vehicle (contact the DOT).c. Immediate movement of the vehicle is necessary in order to protect life or property.Any vehicle transporting DOT hazardous materials which must be placarded must comply with The Federal Motor Carrier Safety Regulations as discussed in 49 CFR 397. These regulations govern vehicle attendance, surveillance, parking, routes, fires, smoking, fueling, tires, and transport of explosives.

2.8.8 Loading

Precautions

1. Segregation and Separation of Hazardous Materials Incompatible materials must be loaded, stored, or transported separately or with some barrier to keep materials separate in case of an accidental release. If a material is not compatible with another material, a reaction will occur when they are combined.

A product's MSDS includes information related to reactivity or incompatibility. The DOT has established some general segregation rules that must be followed (49 CFR 177.848). These are minimum requirements. Additional information may be obtained by review of a MSDS. The DOT guidelines are given in Figure 3-2-5. These rules apply to DOT hazardous materials which are a. in packages which require DOT labels, b. in a compartment within a multicompartmental cargo tank, or c. in a portable tank loaded in a vehicle or freight container.

2. Miscellaneous Driving/Loading/Unloading Rules (49 CFR 177.834)Following are several rules which govern the operation of a motor vehicle carrying hazardous materials including the loading/unloading of hazardous material (see Figure 3-2-7 for a driver's checklist to ensure compliance).

3 -2.27 NAEC Rev. 39 Any tank, barrel, drum, cylinder, or other package not permanently attached to the vehicle must be properly secured when transported aboard a vehicle.No hazardous materials can be carried in or on pole trailers.No smoking is permitted by personnel on or about a motor vehicle while loading or unloading Class 1 explosives, Class 5 oxidizing materials, or Class 2/Class 3/Class 4 flammable materials, or an empty cargo tank which has been used to transport flammable liquids or gases.Hazardous materials must be kept away from potential fire hazards (smoking, lighting matches, any flame, or lighted cigar, pipe, or cigarette). Example: do not start vehicle engine while unloading or loading flammables unless needed to operate an appropriate transfer pump.Do not use tools that are likely to damage the package or its closures.Vehicle hand breaks or air parking brake must be engaged when the vehicle is in a parked position.Wheel chocks must be in place when the vehicle is parked.No motion can be allowed between containers when a vehicle is under way.Containers with valves must be loaded so that the likelihood of damage is minimized. Cargo tanks must be attended by a qualified person at all times during loading and unloading. The individual in attendance must be awake, have unobstructed view of the cargo tank, know what to do in an emergency, and be capable of moving the vehicle.Ensure bulk packages are properly grounded when adding/removing materials to avoid static electricity buildup.Make sure all valves have been properly opened or closed. Make sure there are no spills or leaks.If any item or material being shipped is discovered to be leaking or broken en route, it must be repaired or removed to a safe area before the shipment continues. All required markings, labels, and placards must be maintained in good condition. Be familiar with the Segregation Table for Hazardous Materials (see Figure 3-2-5).2.8.9 Hazardous Material Incidents and Reporting If a vehicle carrying hazardous materials is involved in an accident, DOT mandates specific procedures to be followed. Figure 9, Hazardous Material Accident Reporting Checklist, summarizes actions to be taken during a hazardous material accident. It may be carried upon vehicles as a reference. Actions include the following: 3-2.28 NAEC Rev. 39

1. Notify and obtain help from area emergency response personnel (POLICE/FIRE DEPARTMENT/9 11). The driver may ask a bystander to call local authorities rather than leave the vehicle unattended.

2. As appropriate, call Seabrook Station at (603) 474-9521 and request to be connected to the Control Room.NOTE.These numbers are monitored 24-hours a day; collect calls will be accepted.State your name, location, and telephone number. Give a brief description of the emergency including the hazardous materials involved.3. CALL YOUR SUPERVISOR, if possible.4. Isolate the immediate accident area as appropriate.

NOTE Do not take any actions which are not safe. Emergency response requires specific training, tools, and equipment. Protect yourself and others.5. If safe to do so, remove materials from the immediate area as appropriate.

6. If safe to do so, repair or remove containers in the vehicle as appropriate.

7. Place specific warning devices at the accident site.8. If safe to do so, stop any leaks resulting from the accident.9. Contain any spilled materials resulting from the accident.NOTE For Driver Safety information (i.e., potential hazards and/or first aid) reference the DOT Emergency Response Guidebook (ERG).Reporting requirements are found in Control Room Abnormal Procedure ON 1244.01 and the Regulatory Compliance Manual (NARC).3 -2.29 NAEC Rev. 39 Figure 3-2-1 Definitions of Hazard Classes (Sheet 1 of 4)There are ten (including ORM-D) DOT classes of hazardous materials listed in the Hazardous Materials Regulations.

Technically, ORM-D's are Class 9 materials. The hazard class is the second component of the proper shipping description. The hazard classes have undergone several modifications as a result of HM-181.The ten hazard classes are described below.Hazard Class and Divisions 1. Class 1 -Explosives Any substance or article, including a device, which is designated to function by explosions or which, by chemical reaction within itself, is able to function in a similar manner even if not designated to function by explosion. This class has six divisions: Division 1.1: Explosives that have a mass explosive hazard, one which affects the entire load instantaneously. Division 1.2: Explosives that have a projectile hazard but not a mass explosion hazard.Division 1.3: Explosives that have a fire hazard and either a minor blast hazard or minor projectile hazard or both, but not a mass explosion hazard.Division 1.4: Explosive devices that present a minor explosion hazard and do not contain more than 25g of a detonating material.Division 1.5: Very insensitive explosives. Division 1.6: Extremely insensitive articles which do not have a mass explosive hazard.2. Class 2 -Gases Class 2 is divided into three divisions. Division 2.1: (Flammable Gas) Any material which is a gas at 20 °C (68 o F) or less and 101.3 Kpa (14.7 psi) of pressure which is ignitable when in a mixture of 13 percent or less volume with air or has a flammable range with air of at least 12 percent regardless of the lower limit.Division 2.2: (Nonflammable Gases) Any material or mixture which exerts an absolute pressure of 280 Kpa (41 psia) at 20 C (68 0 F) in the packaging and does not meet the definition of Division 2.1 or 2.7.Division 2.3: (Poisonous Gas) Any material which is a gas at 200 C (680 F) or less and a pressure of 101.3 Kpa and which is known to be so toxic to humans as to pose a hazard to health during transportation of which has an LC 5 0 of not more than 5000 ppm. Other gas definitions are also provided in 49 CFR 173.115.3-2.30 NAEC Rev. 39 Figure 3-2-1 Definitions of Hazard Classes (Sheet 2 of 4)3. Class 3 -Flammable Liquids Any liquid having a flash point of not more than 60.5 C (141 o F), except any liquid meeting one of the definitions specified in 49 CFR 173.115, and except any mixture havingone or more components with a flash point greater than 60.5 C (141 0 F) that makes up at least 99 percent of the total volume of the mixture.Packing Group Designations PG 1 Flash point 730 F (23 0 C)Boiling point > 95 0 F (35 o C)PG II Flash point < 73 0 F (23 0 C)Boiling point > 95 0 F (350 C)PG III Flash point -73 0 F (23 0 C) and-141 o F (60.5 C)Boiling point > 95 0 F (35 0 C)Combustible Liquids Any materials that do not meet the definition of any other hazard class and have a flash point above 60.5 0 C (141 0 F) and below 93 0 C (2000 F). This supersedes the old definition of have a flash point between 38 and 93 C (100-199 0 F).I NOTE The DOT provides an exception for domestic shipments which allows liquids with a flash point between 100 0 F and 140 F to be reclassified as combustible.

4. Class 4 -Flammable Solids This has three divisions.

Division 4.1: (Flammable Solid) Any of three materials: wetting explosives, self-reactive, and readily combustible solids as defined in 49 CFR 173.124.Division 4.2: (Spontaneously Combustible Material) Any material which is pyrophoric or self-heating. A pyrophoric material can ignite within five minutes after coming into contact with air without an ignition source. A self-heating material is one, which upon contact With air, is liable to self-heat as defined in 49 CFR 173.124.3-2.31 NAEC Rev. 39 Figure 3-2-1 Definitions of Hazard Classes (Sheet 3 of 4)Division 4.3: (Dangerous When Wet) Any material which by contact with water is liable to become spontaneously flammable or to give off flammable or toxic gases at a rate greater than 1 liter/kilogram/hour.

5. Class 5 -Oxidizer/Organic Peroxide There are two divisions.

Division 5.1 (Oxidizer) Any material which may cause or enhance the combustion of other materials usually by evolving oxygen.Division 5.2: (Organic Peroxide) Any organic compound containing oxygen in the bivalent (-0-0-) structure and which may be considered a derivative of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic constituents.

6. Class 6 -Poisonous/Infectious Substances Class six has two divisions.

Division 6.1: (Poisonous Material) Any material other than a gas which is known to be so toxic as to afford a hazard to health during transportation. In the absence of human toxicity data, 49CFR 173.123 sets criteria for the determination to be made.Division 6.2: (Infectious Substance) A viable microorganism, or its toxin, which causes or may cause disease in humans or animals, and includes those agents listed in 42 CFR 72.3 of the Department of Health regulations. Infectious substances also include any other agent that has the potential to cause severe, disabling, or fatal disease. The term "infectious substance" replaces the hazard class named "etiological agent." 7. Class 7 -Radioactive Material Any material having a specific activity greater than 0.002 microcuries per gram.8. Class 8 -Corrosive Material A liquid or solid that causes visible destruction or irreversible alterations in human skin tissue at the site of contact, or a liquid that has a severe corrosion rate in steel or aluminum (49 CFR 173.135).Packing Group Designations PG I -Will attack exposed skin when in contact for more than 3 minutes.PG II -Will attack exposed skin when in contact for more than 60 minutes.PG III -Will attack exposed skin when in contact for more than 4 hours.3-2.32 NAEC Rev. 39 Figure 3-2-1 Definitions of Hazard Classes (Sheet 4 of 4)9. Class 9 -Miscellaneous Hazardous Material A material which presents a hazard during transportation but is not included in any other hazard class. This class includes the following:

a. Material which has an anesthetic, noxious, or other similar property which could cause extreme annoyance or discomfort to a flight crew member so as to prevent the correct performance of duty; and b. Material not included in any other hazard class, but is subject to the requirements of 49 CFR because it meets the definition in 49 CFR 171.8 for hazardous substance or a hazardous waste.10. ORM-D Any material, subject to the 49 CFR regulations which presents a limited hazard during transportation due to its form, quantity, or packaging.

In order to be transported under the proper shipping name of "Consumer Commodity," a material must be packaged and distributed in a form intended or suitable for sale through retail sales agencies or instrumentalities for consumption by individuals for the purposes of personal care or household use.The DOT determines the form, quantity, and packaging allowed for materials that may qualify as the Consumer Commodities for each hazard class.3-2.33 NAEC Rev. 39 Figure 3-2-2 Hazardous Material Employee Responsibilities (Sheet 1 of 3)GENERAL All hazardous material employees are required, as a minimum, to receive General Awareness Training and DOT Safety Training.VEHICLE DRIVERS All drivers of vehicles which carry materials classified as hazardous by the Department of Transportation require training. Vehicle Operators are those individuals who control the use of a vehicle which transports hazardous materials over a public highway. A vehicle is a cargo-carrying vehicle (such as an automobile, van, truck, semi-trailer, tank car, tractor, or rail car) which is propelled or drawn by mechanical power and used upon the highways in the transportation of property or passengers. Drivers must possess a Commercial Drivers License (CDL) with a hazardous materials endorsement as a minimum.FPLE Seabrook personnel driving FPLE Seabrook vehicles transporting hazardous materials require function-specific training.Responsibilities

3.0 POLYCHLORINATED

BIPHENYLS (PCBs)3.1 Purpose This section outlines the system policy and general instructions for marking, handling spills, storage, disposal, inspections, notifications and reporting of Polychlorinated Biphenyls (PCBs).3.2 General Polychlorinated Biphenyls (PCBs) are a group of synthetic chlorinated organic compounds. Commercially produced since 1929, PCBs, generically known as askarel, were initially used as dielectric fluid in transformers and capacitors. The advantages of PCBs as an electrical insulator included its nonflammability, thermal stability and resistance to degradation. Common trade names of PCBs used in the manufacture of transformers and capacitors include the following: Aroclor Arochlor B ALC Apirolio Asbestol ASK Askarel Chlorinol Chlorphen Clophen Clorinol Diaclor DK Dykanol Fenclor Hyvol Inclor Inerteen Keneclor Kenneclor Magvar MCS-1489 No-Flamol Nonflammable Liquid Pehnochlor Pydraul Pyralene Pyranol Pyroclor Saf-T-Kuhl Adkarel Capacitor 21 Chlorextol EEC-18 Elemex Cucarel Santotherm Santovac 1 and 2 Nepolin 3.3 Regulations 1I The PCB regulations of May 31, 1979, banned the manufacture, distribution in commerce and use of PCBs unless in a "totally enclosed manner." It also detailed specific storage and disposal requirements.

2. Continued use of existing PCB and PCB-contaminated equipment is authorized with three exceptions.

The first and second involve equipment that may pose an unnecessary risk to human food and animal feed, the third involves equipment that may pose a high risk of exposure to byproducts of PCBs that may be involved in a fire. This third category involves use restrictions for PCB transformers including local fire department and nearby building owner notification, added electrical protection and specific response.actions to-be taken in the event of a fire involving the release of PCBs.3-3.1 NAEC Rev. 39

3.4 Applicability

The guidance in this section applies to all sources and potential sources of PCBs located at Seabrook Station. Figure 3-3-1 provides a listing of sources of PCBs.3.5 References

3.7 Responsibilities

3.7.1 Hazardous

Waste Coordinator Coordinates spill cleanup, sampling, marking, storage and disposal of PCBs.3.7.2 Shift Manager Provides immediate reports to federal, state and local regulatory agencies.3.7.3 Licensing Manager Provides written reports to regulatory agencies. Maintains the records required by this section.3.8 Allowed Assumptions for Equipment While in Use Federal regulations allow certain assumptions to be made regarding transformers and electrical equipment currently in use.NOTE PCB content must be determined prior to equipment disposal for electrical equipment and capacitors assumed to be non-PCB or PCB-free while in use.1. The owner of mineral oil-filled electrical equipment, including transformers, manufactured before July 2, 1979, for which PCB concentration has not been established, must assume the equipment is PCB-contaminated (i.e., contains 50 ppm or greater PCB, but less than .500 ppm PCB). If date of manufacture is unknown, but the dielectric fluid is known to be mineral oil, the owner must assume the unit to be PCB-contaminated. 3-3.2 NAEC Rev. 39

2. Transformers containing

< 1.36 kg of dielectric fluid and manufactured prior to July 2, 1979, may be assumed to be PCB-free while in use.3. The owner or operator of oil-filled electrical equipment, including transformers, manufactured after July 2, 1979, for which PCB concentration is not established, may assume the equipment is non-PCB (i.e., contains less than 50 ppm PCB).4. The owner or operator of a transformer manufactured prior to July 2, 1979, and filled with a fluid other than mineral oil for which PCB concentration has not been established, must assume the transformer is a PCB transformer (i.e., contains 500 or greater ppm PCB) if it contains 1.36 kg (3 lbs.) or more of fluid. The assumption requirement does not apply to "dry" transformers (those containing no fluid). If date of manufacture and the type of dielectric fluid is unknown, the unit must be assumed to be PCB (i.e., > 500 ppm).5. All capacitors manufactured before July 2, 1979 must be assumed to be PCB capacitors with a PCB concentration > 500 ppm unless marked as non-PCB by the manufacturer. Capacitors manufactured after July 2, 1979 may be assumed to be non-PCB capacitors while in use.3.9 Marking Each of the following owned by FPLE Seabrook shall be labeled with an approved mark (see Figure 3-3-3, Marking and Recordkeeping Requirements): NOTE All marks are to be placed in a position on PCB items or transport vehicles so that they can be easily read by any person inspecting or servicing the item or vehicle.1. All PCB Containers.

2. All PCB Transformers.

3. All Large High Voltage PCB Capacitors.

4. All equipment containing a PCB Transformer or a PCB Large High Voltage Capacitor.

5. All PCB Large Low Voltage Capacitors.

6. Electric motors using PCB coolants.7. Hydraulic systems using PCB hydraulic fluids.8. Heat transfer systems (other than PCB Transformers) using PCBs.9. PCB Article Containers containing articles or equipment that must be marked.10. Each storage area used to store PCBs and PCB Items for disposal.3-3.3 NAEC Rev. 39

11. All vault doors, machinery room doors, fences, hallways or means of access, other than grates or manhole covers, to a PCB Capacitor.

This mark must be placed so it can be easily read by emergency response personnel fighting a fire involving this equipment. If one or more PCB Large High Voltage Capacitors are installed in a protected location such as on a power pole, or structure, or behind a fence, then the pole, structure, or fence shall be marked and a record or procedure identifying the PCB Capacitor shall be maintained by the owner or operator at the protected location.12. All transport vehicles (front, back and each side) when transporting > 45 kg of PCB-containing liquid in concentrations -> 50 ppm. Marking is triggered by 45 kg total weight of the material containing 50 ppm or more of PCBs irrespective of the weight of the PCB molecules in the material.3.10 Handling Spills NOTE In addition to the EPA's PCB Spill Cleanup Policy provisions, other CERCLA or RCRA requirements may apply to spill remediation activities particularly if other regulated constituents are present.I1. Based on a current inventory of all oil-filled electrical equipment on this site it has been determined that a spill would most likely occur from a failed PCB Capacitor.

2. The EPA generally expects the decontamination standards of the PCB Spill Cleanup Policy to apply. Occasionally, some small percentage of spills covered by the policy may warrant more stringent cleanup requirements' because of additional routes of exposure or significantly greater exposures than those assumed in developing the final standards of this policy. While EPA Regional Offices have the authority to require additional cleanup in these circumstances, the Regional Administrator must first make a finding based on the specific facts of a spill that additional cleanup must occur to prevent unreasonable risk.Spills in proximity to sensitive human or environmental areas (residential areas, schools, endangered species habitats, wetlands, etc.) may be subject to more stringent remediation requirements as determined by the EPA Regional Administrator based on the site characterization notification.

3. The following actions shall be taken as quickly as possible and within no more than 24 hours after being notified or becoming aware of a spill: a. The employee on site shall immediately notify the Control Room that there has been a spill. The employee shall provide pertinent information such as location, source, amount, PCB concentration of oil (estimate if necessary), etc.b. Contain all spills and leaks as soon as possible.

Care must be taken to prevent the flow or leak of any liquid into any storm drain, sewer, municipal water supply, waterway or other high visibility areas.c. Requirements for personal protection when incontact with or in the immediate vicinity of PCB material have been developed and issued.3-3.4 NAEC Rev. 39

d. For spills involving 1 pound or more of PCBs, the responsible party shall notify the EPA Regional Office, the NRC (National Response Center), and DES Air Resources Division.

The 1 lb. threshold applies to the weight of the PCB waste material, not the specific PCB component in the waste.e. Steps must be taken to effectively cordon off and restrict access to the area where any visible traces of the spill is evident. A buffer zone of three feet around the spill must be established and signs posted in a clearly visible manner advising persons nonessential to the cleanup to avoid the area to minimize the spread of contamination as well as avoiding the potential for human exposure.f. The area of visible contamination shall be documented and recorded, including the center and extent of the Visible trace area. If a spill has occurred and there are no visible traces, a record of that fact shall be made and Licensing will contact the regional office of the EPA for guidance in completing statistical sampling of the spill area to establish spill boundaries.

g. Cleanup of all visible traces of fluid on hard surfaces and the removal of all visible traces of the spill on other areas such as sand, soil, gravel, etc., must be initiated within 24 hours of notification of the spill.If oil has spilled onto vegetation or soil, remove vegetation visibly contacted by the oil. Remove soil visibly contacted plus a one foot buffer zone on all sides.Remove soil to a minimum of 10 inches. Do not replace soils removed since adequacy of cleanup must be determined by post-cleanup sampling.Retain barricade around entire spill area as originally established until the spill cleanup is determined to be complete by analyses of the post-cleanup sampling.h. If response to the site has been delayed and there are insufficient visible traces remaining, an estimate of the contaminated area must be made based on the amount of material missing in the equipment or container.

The area of suspected contamination must be cordoned off immediately and statistically based sampling completed as soon as practical. i.- For spills from transformers containing PCBs or potentially containing PCBs, cleanup must be initiated within 48 hours of discovery. A completion time limit has not been established, but will be decided by the EPA on a case by case basis.The EPA expects that decontamination will be achieved promptly in all cases and will consider promptness of completion in considering whether the responsible party made good faith effort to clean up in accordance with this policy.j. All contaminated solid surfaces shall be cleaned up to 10 mg/100 sq. cm. This is determined by the standard wipe test., Use only approved decontamination procedures listed in 40 CFR 761.79. If a decontamination method under consideration is not listed, EPA approval is required prior to use as the method may constitute disposal.3 -3.5 NAEC Rev. 39

k. Soil contaminated by the spill will be decontaminated to 10 ppm PCBs by weight, provided that the soil is excavated to a minimum of 10 inches. All excavated soil will be replaced with clean soil containing

< 1 ppm PCBs for the spill site to be considered restored.1. The responsible party shall document the cleanup with records of decontamination. The records must be maintained for a period of 5 years.Records shall include the following information: (1) Identification of source of spill (2) Date and time spill occurred (estimate if necessary) (3) Date and time cleanup completed (4) Description of spill location and nature of material contaminated (5) Precleanup sampling data (no visible trace spill)(6) Brief description of solid surfaces cleaned (7) Approximate depth of excavation and amount of soil removed (8) Postcleanup verification sampling data (>500 ppm spill or a no visible trace spill)3.11 Storage for Disposal 1. Temporary storage of the following PCB items scheduled for disposal may occur for a maximum of 30 days provided that a notation is attached to the PCB item indicating the date the item was removed from service: a. Non-leaking PCB Articles and PCB Equipment.

b. Leaking PCB Articles and PCB Equipment if the PCB items are placed in a non-leaking PCB Container that contains sufficient absorbent materials to absorb any liquid PCBs.c. PCB Containers containing non-liquid PCBs such as contaminated soil, rags, and debris.2. Temporary storage areas shall be located in areas least susceptible to accidental damage.3. All equipment stored in temporary storage areas must be labeled as in §3.9.4. All PCB Articles and PCB Containers in storage shall be checked for leaks at least once every 30 days. Any leaking PCB Article and PCB Container shall be transferred immediately to properly marked, non-leaking containers.

5. All items stored in the temporary storage area must be shipped for disposal within 30 days of the date removed from service for disposal.3-3.6 NAEC Rev. 39

6. If storage is to extend beyond 30 days, the more restrictive conditions of 40 CFR 761.65 would apply.7. All storage areas must have floors and curbing constructed of Portland cement, concrete, or a continuous, smooth, nonporous surface as defined in 40 CFR 761.3 to prevent or minimize penetration of PCBs. The EPA recommends that nonporous surfaces be used for curbing and flooring of storage units as cleanup of nonporous surfaces is easier and less costly. The EPA also recommends that porous surfaces be rendered nonporous by coating them with an epoxy sealant.8. Any mixed waste containing PCBs at concentrations

> 50 ppm is subject to the storage and disposal requirements of 40 CFR 761. PCB/radioactive mixed waste removed from service for disposal is exempt from the 1-year time limit for storage provided that a written record documenting all continuing attempts to secure disposal is maintained and the written record is available for inspection or submission, if requested by the EPA.-3.12 Records 1. Licensing shall develop and maintain such records and documents as required under 40 CFR 761 Subpart J, "General Records and Reports." (See Figure 3-3-3, Marking and Recordkeeping Requirements.) NOTE Unless otherwise noted in the regulations, references to weights or volumes in part 761 apply to the total weight or volume of the PCB containingmaterial (oil, soil, etc.), not the calculation weight or volume of the PCB molecules within the material.2. Each owner or operator of a facility, other than a commercial storer or disposer of PCB waste, using or storing at any one time 45 kilograms (approximately 100 lbs) or more of PCBs in PCB Containers, or one or more PCB Transformers, or 50 or more PCB Large High or Low Voltage Capacitors, shall develop and maintain Annual Records and written Annual Document Logs on the disposition of all PCBs and PCB items. These records and logs shall be prepared by July 1 of each year covering the previous calendar year (January through December). These records and logs shall be maintained for at least three years after the facility ceases to use or store PCBs and PCB items.The Annual Document Log shall be available for inspection by authorized representatives of the EPA during normal business hours at the facility where they are maintained and each owner or operator of a facility subject to these requirements shall know the location of these records. The Annual Document Log requirement does not currently apply to Seabrook Station as the threshold requirements are not met.a. Annual Records must include (1) all signed PCB manifests generated during the calendar year.(2) all certificates of PCB disposal received during the calendar year.3-3.7 NAEC Rev. 39

b. Annual Document Log must contain (1) the name, address, and EPA identification number of the facility and the calendar year covered by the log.(2) the unique manifest number of each manifest generated by the facility during the calendar year.(3) the serial number (if available) or other means of identifying'each PCB Article (transformer, capacitor, etc.), weight in kilograms of PCB waste in each, date removed from service for disposal, date placed in transport for offsite storage or disposal, and date of disposal, if known.(4) a unique number identifying each PCB Container, a description of the contents (liquid, solid, soil, cleanup debris, etc.), including total weight of material in kilograms in each container, the first date material was placed in each PCB Container, the date each container was placed in transport for offsite storage or disposal, and the date of disposal, if known.(5) a unique number identifying each PCB Article Container, a description of the contents (pipes, capacitors, motors, pumps, etc.) including the total weight in kilograms of the contents of each PCB Article Container, date each PCB Article was placed in the PCB Article Container for disposal, total weight in kilograms of PCB Articles in each PCB Article Container, ,the date each PCB Article Container was placed in transport for offsite storage or disposal, and the date of disposal, if known.(6) the total number by specific type of PCB Articles and the total weight in kilograms of PCBs in PCB Articles, the total number of PCB Article Containers and total weight in kilograms of the contents of PCB Article Containers, the total number of PCB Containers and the total weight in kilograms of the contents of the PCB Containers, and the total weight in kilograms of bulk PCB waste that was placed in storage for disposal or disposed of during the calendar year.(7) the total number of Large Low or High Voltage PCB Capacitors remaining in service at the end of the calendar year.(8) the total weight in kilograms of any PCBs and PCB Items in PCB Containers, including the identification of container contents remaining in service at the end of the calendar year.3.13 Processing and Disposal 1. In order to be burned for energy recovery, waste oil collected on site must meet the criteria for specification used oil in accordance with the provisions of Waste Management Rules ENV-Wm 807.02 and the facility Title V Air Emissions Permit. The specifications limit PCB content to < 2 ppm on a dry weight basis. Waste oil with a PCB content of> 2 ppm may not be burned for energy recovery in space heaters currently in use at Seabrook Station.3-3.8 NAEC Rev. 39 Additionally, any waste oil containing

>- 2 ppm PCBs may not be blended with other fuel oil or waste oil (dilution) to bring the waste oil into compliance with used oil specifications. Waste oil containing -> 2 ppm PCBs must be disposed of as hazardous waste in accordance with RCRA requirements. Waste oil containing -- 50 ppm PCBs must be disposed of as PCB% waste in accordance with TSCA requirements.

2. PCB liquid waste to remediation waste from a PCB spill containing

-> 500 ppm PCBs on a dry weight basis may only, be disposed of at an EPA approved incineration unit in accordance with 40 CFR 761.75. The only known source of PCBs at Seabrook Station with concentrations of -> 500 ppm are PCB capacitors. Any leakage from these capacitors is considered. a release requiring a spill response as described in §3.10.3. If intact and not, leaking, small PCB capacitors may be disposed of in a municipal landfill, however, the generator would be subject to liability under CERCLA in the event of any subsequent releases from the landfill. The EPA recommends that small PCB capacitors be disposed of at authorized PCB incineration units. Small PCB, capacitors are properly disposed of by the Hazardous Waste Coordinator.

4. Incidental liquid waste that has become contaminated from exposure to nonliquid PCBs such as condensate, leachate, precipitation, and load separation are the only liquid PCB wastes permitted for landfill disposal.

All other liquid PCB-contaminated waste streams require incineration or approved alternative disposal.5. Drained PCB-contaminated electrical equipment, drained PCB articles, and waste oil containing > 50 ppm PCBs may be disposed of in an approved scrap metal recovery oven or smelter. This also includes metal surfaces which are included in PCB remediation wastes and PCB bulk product waste. Metal in PCB remediation waste includes scrap metal found in an industrial sludge lagoon or rinsed drums formerly used to contain cleanup solvents. Metal in PCB bulk product waste includes pieces from disassembled drained PCB-contaminated transformers or metal surfaces coated with nonliquid PCBs such as painted pieces of fuel tanks. Nonmetal PCB remediation wastes (e.g., liquids, soils, sludges, and dredged sediments) and nonmetal PCB bulk product waste (e.g., shredder fluff and air handling system gaskets) are not approved for disposal in scrap metal recovery ovens and smelters.6. PCB content is to be determined using ASTM Method D-4059, Standard Method for Analysis of Polychlorinated Biphenyls in Insulating Liquids by Gas Chromatography, or other approved method outlined in SW-846, Test Methods for Evaluating Solid Waste.7. Advanced written EPA approval is required for use of alternate disposal methods other than incineration.

8. Components in PCB-contaminated electrical equipment containing liquid PCBs must be removed prior to equipment disposal.

PCB liquids must be disposed of in an authorized incinerator. The contaminated equipment from which PCBs have been removed may be disposed of in a TSCA approved disposal facility.3-3.9 NAEC Rev. 39 3.14 Manifests NOTE Unless otherwise noted in regulations, references to weights or volumes in part 761 apply to-the total weight or volume of the PCB containing material (oil, soil, etc.), not the calculated weight or volume of the PCB molecules within the material.1. A generator who offers PCB waste for transport to a commercial offsite storage or offsite disposal area shall prepare a manifest on EPA Form 8700-22 which shall specify: a. For each PCB Article Container or PCB Container, a unique identifying number, the type of waste (i.e., soil, debris, etc.), earliest date removed from service for disposal, and weight in kilograms of the PCB waste.b. For each article not in a PCB Container or PCB Article Container, a serial number or other identifying number, date removed from service for disposal, and the weight in kilograms of PCB waste in each PCB Article.2. If the state to which the shipment is manifested, (i.e., the consignment state) supplies the manifest and requires its use, the generator must use that manifest.3. If the consignment state does not supply the manifest and the generator state does supply the manifest and requires its use, the generator must use that manifest.4. If both the consignment state and generator state supply the manifests and require their use, the generator must use the consignment state manifest.5. If neither state supplies the manifest, the generator may obtain the manifest from any source.6. The generator must designate one off-site commercial storage or disposal facility approved to handle the PCB waste. If the transporter is unable to deliver the waste, he.must contact the generator for further instructions.

7. These requirements apply to all PCB waste over 50 ppm PCBs and also include all waste less than 50 ppm PCBs if the concentration was the result of dilution.8. The generator must sign themanifest by hand, obtain a handwritten, signed, and dated copy of the manifest from the initial transporter, retain a copy for recordkeeping purposes, and give the remaining copies to the transporter.

3-3.10 NAEC Rev. 39

9. If the generator does not receive a copy of the manifest signed by the commercial storer or disposer within 35 days after the waste was accepted by the initial transporter, the generator shall contact the initial transporter or owner/operator of the designated facility to determine the status of the waste. If a signed copy of the manifest is not received from the designated facility within 45 days of the date the waste was accepted by the initial transporter, an Exception Report shall be submitted to the EPA Regional Administrator.

If a generator transfers PCBs or PCB Items to a disposerlmore than 9 months from the date of removal from service for disposal or has not received a Certificate of Disposal within 12 months from the date of removal from service for disposal, a One Year Exception Report must be filed with the EPARegional Administrator within the next 45 days. The Hazardous Waste Coordinator will be responsible for initiating this function.10. Disposal of all PCB material shall be the responsibility of the Hazardous Waste Coordinator. 3.15 Transport NOTE Unless otherwise noted in regulations, references to weights or volumes in part 761 apply to the total weight or volume of the PCB containing material (oil, soil, etc.), not the calculated weight or volume of the PCB molecules within the material.The Hazardous Material Transportation Act (HMTA) is the basic federal safety net for hazardous materials in transit. Its intent is to adopt such measures which are deemed necessary to protect public health and safety during hazardous materials transport. The Department of Transportation (DOT) has adopted regulations covering all aspects of the safe transportation and handling of these materials by all modes of transport. These regulations include standards for packaging, labeling, marking and routing.1. PCBs are a hazardous substance if a reportable quantity (RQ) is present. The RQ for PCBs is one pound. Askarel filled capacitors and transformers contain more than one pound of PCBs. The one pound threshold applies to the weight of the PCB waste material, not the specific PCB component in the waste.2. All PCBs shipped for disposal must be listed on a manifest, EPA form 8700-22, which shall specify the following DOT proper shipping names: a.

Spill: Both intentional and unintentional spills, leaks, and other uncontrolled discharges where release results in any quantity of PCBs running off or about to run off the external surface of the equipment as well as the contamination resulting from those releases. This section applies to spills of 50 ppm or greater PCBs. The concentration of PCBs spilled is determined by the PCB concentration in the material spilled as opposed to the concentration of PCBs in the material onto which the PCBs were spilled. Where a spill of untested mineral oil occurs, the oil is presumed to contain greater than 50 ppm, but less than 500 ppm PCBs and is subject to the relevant requirements of this section.29. Spill Area: The area of soil on which visible traces of the spill can be observed plus a buffer zone of one foot beyond the visible traces. Any surface or object within the visible trace area or on which visible traces of the spilled material are observed is included in the spill area.30. Spill Boundaries: The actual area of contamination as determined by post-cleanup verification sampling or by pre-cleanup sampling to determine actual spill boundaries.

31. Standard Wipe Test: For spills of high concentration PCBs on solid surfaces, cleanup to numerical standards and sampling by a standard wipe test to verify that the numerical standards have been met. A standard size template (10 cm X 10 cm) will be used to delineate the area of the cleanup; the wiping medium will be a gauze pad or glass wool of known size which has been saturated with hexane. It is important that the wipe be performed very quickly after the hexane is exposed to air. EPA strongly recommends that the gauze (or glass wool be prepared with hexane in the laboratory and that the wiping medium be stored in sealed glass vials until it is used for the wipe test. Further, EPA requires the collection and testing of field blanks and replicates.

6.0 CHAPTER

3 NAEC FORMS Reproducible copies of the following NAEC FORMs for Chapter 3 are included in this section: NAEC FORM 3-2A NAEC FORM 3-2B Hazardous Materials Shipping Paper Hazardous Material Emergency Response Information (49 CFR 171.15, 171.16)REV.:32 20 3-6.1 NAEC Rev. 32 1.0 OIL STORAGE 1.1 Purpose This section describes'the administrative control measures to protect waterways from oil discharges pursuant to the requirements under the Clean Water Act of 1972 and the Oil Pollution Prevention Act of 1990.The Clean Water Act prohibits the discharge of harmful quantities of oil into the navigable waters of the United States. The United States Environmental Protection Agency (EPA), the Coast Guard (USCG) and the New Hampshire Department of Environmental Services (NHDES)have created regulations designed to protect waterways from oil discharges. The EPA regulation (40 CFR 112) requires certain facilities that drill, produce, gather, store, process, refine, transfer or consume oil and oil products to prepare a Spill Prevention Control and Countermeasure (SPCC) Plan.SPCC Plans are a cornerstone of EPA's strategy to prevent oil spills from reaching our nation's waters. Unlike oil spill contingency plans that typically address spill cleanup measures after a spill has occurred, SPCC Plans ensure that facilities put in place containment and other countermeasures that would prevent oil spills that could reach navigable waters. SPCC Plans are designed to complement existing laws, regulations, rules, standards, policies, and procedures pertaining to safety standards, fire prevention, andpollution prevention rules. The purpose of an SPCC Plan is to form a comprehensive Federal/State spill prevention program that minimizes the potential for discharges. Under EPA's Oil Pollution Prevention regulation, facilities must detail and implement spill prevention and control measures in their SPCC Plans. A spill contingency plan is required as part of the SPCC Plan if a facility is unable to provide secondary containment (e.g., berms surrounding the oil storage tank).The SPCC Plan developed for Seabrook Station employs both procedures and plans, as well as identifying physical structures and systems used to prevent and contain discharges of oil. In addition, the SPCC Plan addresses the prevention of releasing hazardous chemicals and hazardous wastes that are used and/or stored at Seabrook Station into or upon navigable waters.The SPCC Plan is contained in Appendix C.1.2 Applicability The applicable regulations require that any facility using or storing oil, which, due to its location, could reasonably expect spilled oil to reach navigable waters of the United States, and meets one or more of the following criteria, must develop a plan (i.e., SPCC) certified by a Registered Professional Engineer, to prevent any discharge of oil. These criteria are as follows: 1. Above ground storage capacity in a single container is in excess of 660 gallons, 2. Aggregate storage capacity is greater than 1,320 gallons (counting containers 55 gallons or greater), or 3. Total underground (completely buried) storage capacity is greater than 42,000 gallons.Containers less than 55 gallons capacity are exempt from SPCC planning per 40 CFR 112.1 (d)(5)and, therefore, are not specifically incorporated in the SPCC Plan. However, spill control measures for such containers are required by federal and state regulations and therefore addressed in Section 1.6.7, Containers, Drums and Temporary Equipment Management Program.4-1.1 NAEC Rev. 40

1.6.1 General

Spill Controls and Precautions for Aboveground Oil Storage and Usage Locations 1. Oil-containing systems will be maintained in a secure manner such that only authorized personnel are allowed to operate valves, pumps, and transfer stations, in accordance with written station procedures.

2. Fill pipes, drain valves, caps and covers on outdoor oil and chemical containers

/drums shall be tightly capped or locked in the closed position when not in use.4-1.5 NAEC Rev. 40

3. Stationary oil storage equipment cannot be installed in areas having a direct pathway to the environment unless protected by a berm of sufficient size to contain the maximum spill.4. Temporary and portable oil storage container/tanks are not permitted in areas having a direct pathway to the environment (wetlands, surface .water, wells, property lines, floodzones, and drainage areas), unless at least one of the following occurs: NOTE On no account, shall any container containing, or has contained, Hazardous Waste be stored outdoors within 50 feet of such areas (a) The container is under the direct control of workers with constant awareness, and who could immediately respond to prevent a spill.Example: Leaving a 2.5 gallon gasoline container next to a stream or storm drain while mowing the grass would not be considered under constant awareness because immediate response to prevent surface water pollution would not be possible.

However, leaving the container in an areafar removed (>50 feet) from streams, storm drains or nearby wells would be acceptable provided additional common sense precautions are taken to ensure: (1) the container is securely capped and placed in a manner that it won't tip over spilling its contents onto the ground, (2) the worker is aware of its location and has reasonable expectations that the container will not be tampered with while left unattended, and (3) the container is not left unattended for longer than one working shift.(b) A spill would be detected under normal Station surveillances before release to the environment occurs, i.e., Operations has been notified of the location of the temporary container such that it would be surveilled during routine shiftly rounds.Note: A container left by a storm drain in the GOB parking lot would not qualify since Operations personnel do not normally surveil this area.(c) Installing a temporary berm to provide secondary containment around the container or yard drains. A temporary berm can be in the form of oil absorbent pillows, oil "pigs" (sausages), sand, speedy dry, etc.Note: (1) The type of temporary berm selected/used must be appropriate for the application to ensure proper secondary containment. Licensing should be contacted for guidance toensure that the spill control measures are appropriate for the specific application.

• (2) Temporary berms shall be periodically inspected and maintained as necessary, while deployed.4-1.6 NAEC Rev. 40

5. Whenever bulk transfers of oil or chemicals are made, storm drains that may be impacted (within 50 feet downgrade) by an oil/chemical spill shall be protected with covers, dikes or berms to preclude the discharge of these materials to the environment during transfers.

6. Workers required to handle or use oil in areas having a direct pathway to the environment are to minimize the volume handled and use good housekeeping practices.

7. Drip pans should be used for mobile equipment to collect incidental leakage.8. Oil residues from equipment in use in areas having a direct pathway to the environment must be immediately contained or cleaned up with oil absorbent materials.

9. Station personnel should, particularly for non-routine evolutions, contact Licensing to conduct an assessment of specific spill prevention needs on a case-by-case basis to ensure effective oil spill controls.

Evolutions such as routine fuel or chemical deliveries will not be subjected to prior review by Licensing provided such evolutions are controlled by station procedures, specific to the evolution.

10. The Contract Coordinator or department responsible for the evolution involving the flushing or transfer of oil and hazardous substances will confirm prior to performing the evolution, that the environmental requirements in Attachment B of the SPCC Plan have been satisfied.

Note: To ensure compliance with applicable state and federal requirements, Licensing personnel may specify additional criteria. Any exceptions to the Attachment B criteria established for each evolution will be provided by Licensing and documented for inclusion in the work package.11. Prior to the performance of any non-routine evolution involving the flushing or transfer of oil or other hazardous substances, an inspection of hoses and associated couplings must be performed and ensure spill prevention controls have been implemented. Refer to Section 1.6.7 below and Attachment B of the SPCC Plan guidelines for hoses and associated couplings.

12. *Whenever any type of oil / chemical transfer will occur, supervisors

/ operators must be cognizant of the likelihood of fluctuating flow rate and potential problems associated with changing product temperature during the transfer.Example: Tanker truck with cold fuel oil filling a heated stationary tank that is inservice supplying operating equipment, whereby temperature changes in tank contents, whether mixed or stratified, may cause inservice equipment to operate erratically or malfunction.

13. If tanker truck unloading is not governed by station procedures, the generalized

• unloading procedures in Attachment C of the SPCC Plan shall be used. Licensing must approve any deviation from this guideline and may impose additional requirements.

4-1.7 NAEC Rev. 40

14. Whenever an oil transport vehicle (tanker truck, railcar, or other vehicle engaged in the transport of oil) is used for bulk transfer of oil, the transfer should occur within an area constructed of a concrete pad or other impermeable surface.Note: (1) If the transfer is from the oil transport vehicle to an AST system the impermeable area shall be of sufficient size so that all connection points are situated over the impermeable area; however, (2) If the transfer is from an AST system to the oil transport vehicle then the entire portion of the oil transport vehicle being filled must be situated over the impermeable area while being.filled.

(3) Direct transfer of oil from one oil transport vehicle to another is prohibited except during an emergency situation, as authorized by emergency response personnel. (4) Transfer areas that do not have impermeable surfaces must be evaluated by Licensing on a case-by-case basis before the transfer occurs.15. Temporary portable berms must be used at transfer areas that do not have permanent containment provisions at the loading/unloading truck connections or equipment fill line connections. These areas include but are not limited to:* Dirty oil truck connection at 1-LO-V-148, Turbine Bldg. south side* Clean oil truck connection at 1-LO-V-85, Turbine Bldg. south side* Fuel oil fill connection for both SEPS diesel generator tanks* Temporary onsite equipment (e.g., air compressors, generators, portable storage tanks, etc.) must be evaluated by Licensing on a case-by-case basis;however as a minimum, nearby storm drains within 50 feet downgrade must be covered / blocked during transfer.Additionally, a mobile/ temporary secondary containment system shall be setup at job location whenever the mobile Hipotronics Resonant Test System is used.16. During fuel deliveries a 5-gallon or greater catch bucket shall be used if the loading connection is either not within secondary containment or does not have an integral secondary containment.

17. During filling / fuel transfer operations, station personnel assigned to the transfer evolution shall:* Block nearby storm drains as necessary (within 50 feet downgrade),* Use available level indications to monitor the transfer,* Be in direct communication with the tank truck operator, and* Have the ability to stop the transfer in the event of a problem or spill.18. All fueling operations associated with the Vehicle Maintenance Shop Gasoline and Diesel Fuel Storage Tanks shall be continuously monitored.

4-1.8 NAEC Rev. 40

19. When oil transfer on the station transformers is necessary, all necessary oil spill equipment will be assured. for immediate availability.

20. Station operations personnel shall check all oil/water separator vault control panels daily.21. To ensure that drainage does not inadvertently discharge to an in-plant treatment system (like an oil/water separator vault), dewatering valves and controls for secondary containment

/ diked areas are to be normally maintained in the locked-closed / off position, or operated by a specialty tool (e.g., T-handle). 1.6.2 Oil Sheen and Dewatering of Accumulated Precipitation Note: (1) Allowable discharges to storm drains or building drains are controlled through the non-radiological release permit procedure CP 9.3, "Non-Radiological Effluent Releases," in order to ensure NPDES Permit compliance. (2) Licensing environmental personnel must be notified if oil sheen or oil is observed in any dike area prior to draining dike area.1. Secondary containment / diked areas shall be periodically dewatered (after visually checking for oil sheen) from accumulated precipitation as soon as possible and frequently enough to ensure the secondary containment / dike is able to contain the entire contents of the tank should a rupture event occur.2. If only a slight oil sheen is observed on the water surface in the diked areas, the oily water must be collected and processed in one of the oil/water separator vaults, or collected and processed by other suitable means (e.g., waste collection container/drum or tanker).3. Excessive oily water (more than a slight sheen) shall not be discharged to or be processed through the station's oil/water separator vaults. Licensing must be contacted for determination of proper handling and disposal.4. Draining of accumulated precipitation in the secondary containment enclosure for the Vehicle Maintenance Shop Gasoline and Diesel Fuel Storage Tanks to the local storm drain shall not be performed if there is oil sheen on the water.Licensing must be contacted for determination of proper handling and disposal.5. Prior to discharging/draining Sump 4 (fire pumphouse) to Oil / Water Separator Vault No. 3, the sump must be inspected for the presence of oil.1.6.3 Oil Spills 1. In the event of an oil spill, immediately notify the Control Room and follow the requirements of station procedure ON1244.01, "Oil/Chemical Spill," and actions addressed in the SPCC Plan. Obtain spill-diking materials from the nearest spill kit, or as otherwise available, and contain the spill.4-1.9 NAEC Rev. 40

2. If an oil or chemical spill reaches the storm drain system, refer to the storm drain system diagram in Figure 3 of the SPCC Plan and take appropriate action to prevent oil or chemicals from reaching Manhole 34 (Storm Drain System connection to Circulating Water System piping).3. Oil spills involving Polychlorinated Biphenyls (PCBs) require additional control measures and shall be managed in accordance with NAEC Chapter 3, Section 3.0.4. Prior to spill cleanup (depending on type and size of spill), any emergency showers or eyewash stations in the area of the spill must be operational.

Ifthese are not available, a hose and dedicated person shall be present for personnel protection. The Incident Commander / SERC will make the determination for need of emergency showers or eyewash stations.5. The Hazardous Waste Coordinator shall ensure that all wastes generated as a result of a spill and follow-up cleanup are managed in accordance with Hazardous Wastes Department Instructions for on-site storage and/or shipment.6. Prior to resuming activities in the area of the oil spill the Fire Protection Supervisor shall ensure that all spill response equipment has been restored.1.6.4 Reporting Requirements Refer to the Regulatory Compliance Manual (NARC), Chapter 3, for reporting requirements to State, Federal and Local agencies.1 6.5 Maintaining the SPCC Plan 1. Regulatory Compliance personnel maintain the SPCC Plan. The SPCC Plan will be made available to the EPA and NHDES representatives during normal working hours if requested during an audit.2. Pursuant to 40 CFR 112.5(a), the SPCC must be revised to reflect any changes to the facility whenever there is a change in design, construction, operation, or maintenance which materially affects the potential for discharge of oil. The revision must made be as soon as possible, but no later than six (6) months after the change is made.3. The spill contingency portion of the plan will be reviewed and amended immediately Whenever: a. Applicable regulations are revised, b. The plan fails in an emergency, c. The facility changes in its design, construction, operation, maintenance or other circumstances in a way that materially increases the potential for fires, explosions or releases of hazardous waste or hazardous waste constituents, or changes the response necessary in an emergency, d. The list of emergency coordinators changes, or 4-1.10 NAEC Rev. 40

e. The list of emergency equipment changes.4. The SPCC Plan must be approved and certified by a professional engineer registered in the State of New Hampshire.

5. Licensing shall initiate a review of the SPCC Plan every five (5) years and amend the plan within six (6) months of such review to include more effective prevention and control technology if available and proven (40 CFR 112.5(b)).

A professional engineer registered in the State of New Hampshire shall certify each 5-year review of the SPCC Plan.6. Technical amendments to the SPCC Plan shall be certified by a State of New Hampshire Registered Professional Engineer within six (6) months after a change.Non-technical amendments (e.g., contact information) do not require additional review and certification by a registered professional engineer but shall be recorded in the SPCC Plan's "Summary of Changes," noting the date of incorporation and the description of the amendment. 1.6.6 Tank and Associated Piping Management Program Note: The requirements stated herein are excerpts from NHDES Waste Management Administrative Rule Part Env-Wm 1402, Control of Aboveground Petroleum Storage Facilities.

a. General Design and Construction Requirements

1. Tanks and containers used for storage will be engineered to contain, and shall be compatible with, the materials being stored and the storage conditions.

2. Aboveground tanks constructed after April 25, 1997 must comply with NHDES Env-Wm 1402.21 requiring secondary containment with sufficient freeboard to accommodate 24 hour precipitation during a 10-year storm event or 110% capacity of the largest tank within the enclosure, whichever is greater.3. Secondary containments shall be constructed so that spills will not permeate into the soil more than one foot in 72 hours, or infiltrate or otherwise escape to the groundwater or surface waters before clean-up occurs. (NHDES Env--1402.21).Note: The purpose of secondary containment is to stop (contain) the oil from moving and creating more environmental damage and cleanup.Any impact to soils of berms or dikes, or traprock over soils that meet the definition above is not an issue.4. Drainage from secondary containments will be controlled by manually operated valves such that collected water may be inspected for oil contamination and treated as necessary prior to discharge.

4-1.11 NAEC Rev. 40

5. Secondary containment drain pipes shall be designed and constructed to prevent a release in the event' of a fire.6. Consideration will be given to providing easy-read level gauges, high-level alarms, high-level pump cutoffs, and direct communication between level gauges and pumping stations.

-7. New transformers shall meet the requirements of Env-Wm-1402.32.

8. New oil piping shall be installed aboveground whenever possible and shall be protected from collision either by location or by protective measures (e.g., bollards, walls, etc.).9. New underground piping systems must be double-walled pipe or set in an engineered trench liner per Env-Wm 1402.22. Such piping must also be provided with leak detection within the piping interstitial space, or annular space for secondary containment systems, per Env-Wm 1401.27.10. New underground secondary containment metal piping must be protectively wrapped and provided with cathodic protection (40 CFR 1 12.8(d)(1)

& Env-Wm 1402.19).11. Existing underground pipelines not in active use shall be marked as to origin and securely valved-close and/or blanked/capped at termination points to prevent leakage and line contamination.

b. Inspection and Test Requirements

1. Inspections and tests will be performed in accordance with approved written procedures.

2. A API or STI-certified tank inspector shall perform non-routine tank inspections.

Such inspections shall be performed in accordance with API 653 or STI SP001-05.3. Tank inspections shall be performed at an interval determined by the API or STI-certified tank inspector.

4. Inspection frequency and type of testing must take into account container size and design (such as floating roof, skid-mounted, elevated, or partially buried). However, in no case shall the inspections or testing interval exceed the stated acceptable intervals, as documented in the respective standards and summarized in Tables 2 and 3 of the SPCC Plan.5. Cleaning and inspection of tanks greater than 5,100 gallons capacity shall be periodically performed in accordance with Env-Wm 1402.29(c) and (d)..Every five (5) years for gasoline tanks, and.Every ten (10) years for oil tanks.4-1.12 NAEC Rev. 40 Note: (1) Technical Requirements Program (TRP) 5.1 only governs cleaning of the Emergency Diesel Generator Fuel Oil Storage Tanks. Inspection and testing is per NHDES requirements.

(2) The intervals stated here and elsewhere in this section are maximums, no grace period is allowed unless written permission for extension is approved by NHDES. This requirement supercedes any grace period extensions allowed by either the Technical Specifications or Technical Requirements.

6. Internal appurtenances must be inspected each time the tank is cleaned.7. All oil storage tanks are subject to the above requirements; however, regularly scheduled tank inspection and testing of tanks less than 5,100 gallons shall not be required, as long as the followingconditions are met: a. The tank is designed, constructed, installed, maintained and inspected in accordance with the manufacturer's requirements and all applicable standards;

b. The entirety of the tank (including bottom) can be visually inspected;

c. The bottom of the tank is elevated to prevent direct contact with the ground;d. Regular visual inspections of the tank show no abnormal conditions that could affect shell wall or bottom thickness (e.g., corrosion, contact with water, coating failure, chaffing at supports, corrosion within the tank vent); and e. No modifications are made to the tank.Note: If regular inspections of tanks less than 5,100 gals. indicate a wall or bottom thickness concern then certified inspections or integrity testing must be performed.

8. Notwithstanding the above exclusion for tanks less than 5,100 gallons capacity, these tanks are required to be internally inspected at a maximum interval of: STI -ten (10 ) years; and API -twenty (20) years, unless the bottom corrosion rates are unknown than every ten (10) years per API 653-2001, Section 6.4.2.2.9. Visual inspections combined with regular tank integrity testing, as required per 40 CFR1 12.8(c)(6)

& NHDES Env-Wm 1402.29(d), must be performed for all applicable aboveground containers on a regular schedule, and whenever material repairs or other tank construction is undertaken. These requirements do not apply to oil filled equipment, including electrical transformers or underground storage tanks.4-1.13 NAEC Rev. 40

10. Inspections may include tank thickness measurements (ultrasonic testing or magnaflux gauging) and other integrity testing techniques such as hydrostatic testing, radiographic testing, acoustic emissions testing, or another system of non-destructive shell testing. Records must be retained to provide comparisons between tests.11. Internal inspections subject to the requirements of Env-Wm 1402.29 must also include tightness testing for all connected underground piping (in accordance with NFPA 30 or manufacturer's specifications), as well as the visual inspection of the tank's interior per Env-Wm 1402.29(e).

Note: Robotic inservice internal inspection equipment cannot be used to fulfill these requirements.

12. If deficiencies are identified during the inspection, the tank will be repaired as soon as possible.

Depending on severity of the deficiency, inservice tanks may be taken out of service and pumped down in accordance with Env-Wm 1402.11.13. In the event that an abnormal condition is observed, which could affect tank shell or bottom thickness, integrity testing shall be performed as soon as practicable. Follow up testing shall be in accordance with the mandatory provisions of this section.14. Tanks (regardless of capacity) must also be inspected whenever making material (significant) changes in service or repair, in accordance with 40 CFR 112.8(c)(6) and Env-Wm 1402.11 15. After tank repairs, alterations, reconstruction or change in service, an assessment shall be performed to determine if brittle fracture tests are required (40 CFR 112.7(i)). The methodology for determining whether a brittle fracture test should be conducted will be in accordance with API 653 Section 5 by a certified API 653 inspector.

16. Underground piping must be leak and integrity tested at time of installation, modification, construction, relocation or replacement per 40 CFR 112.8. Testing should follow guidelines provided in API 570 Section 9 or equivalent.

17. Periodic integrity testing of underground piping is not required.

However, such integrity or leak testing may be necessary if visual inspection shows evidence of leaks (such as oil percolation, stressed vegetation around pipeline areas, etc.) or tank inventory reconciliation shows evidence of loss. This is especially critical in pipelines, which are not cathodically protected and the soil resistivity is less than 2,000 ohm-cm.18. If a section of underground oil pipeline is exposed, it will be examined for deterioration (e.g., coating, wrapping, corrosion). 4-1.14 NAEC Rev. 40

19. If water or product is detected in the interstitial space of a double-walled tank, the tank shall be inspected to determine the source. If determined to be a potential failure of the tank wall (either inner or outer) the tank shall be immediately placed out of service until repairs can be made.Accumulated storm water or condensation within the interstitial space will be removed and processed through the oil/water separator or by other suitable means.c. Surveillance Requirements I1. Above ground oil storage tanks (AST) are subject to weekly and monthly visual external inspections in accordance with 40 CFR 112.7(e)(2)(vi), NHDES Env-Wm 1402.29 and the Storm Water MUlti-Sector General Permit (Section 6.0.4.2.8).

The Weekly inspections include: (1) Tank exteriors and exposed piping for evidence of leaks, damage or weeping;(2) Secondary containment systems including, walls, bases and diversionary structures for damage and degradation, especially in areas where piping penetrates the containment; and (3) Checking storm water discharge valves and drainage systems for proper control position and to ensure that the valves for gravity drains are locked or otherwise secured from tampering. The Monthly inspections include the following: (1) Testing tank monitoring systems for proper operation, including interstitial monitors and high level alarms;(2) Testing impressed current cathodic protection systems (where provided) for tank bottoms;(3) Inventory reconciliation for tanks in contact with the ground (per Env-Wm 1402.09);(4) Spill control equipment and temporary secondary containment equipment for proper inventory and acceptable condition; and (5) Above ground piping systems associated with oil storage tanks should be visually surveyed as part of monthly inspections. Supports, foundations and secondary containments are also included in these inspections.

2. Monthly inventory monitoring shall be performed on aboveground storage tank systems where any portion of the primary tank shell, primary piping, or both, is in contact with the ground, soil, or concrete foundation slab and does not have release detection pursuant to Env-Wm 1402.28. Inventory monitoring consists of: 4-1.15 NAEC Rev. 40 (a) Reconciling AST inventory control measurements by comparing product measurements with shipments, deliveries, and internal transfers.(b) Investigating and resolving the cause of any significant loss in inventory, such as any unexplained difference of 2.0 percent or more of throughput in one month, as indicated by the recording and reconciliation of inventory records.-(c) Maintaining separate records for each AST or interconnected system, certifying the accuracy of the inventory monitoring.

If an unexplained physical loss of oil is evident following the investigation, NHDES shall be notified immediately. Note: Currently, the Auxiliary Boiler Fuel Oil Tank (1-AB-TK-29) is the only AST onsite subject to inventory monitoring.

3. Monthly visual inspections shall be performed on all aboveground oil-filled electrical equipment (station, substation, load center and construction transformers), storage tanks, and associated structures (piping, sumps, dikes, etc.). Inspections entail: (1) Exteriors of electrical equipment for signs of leaks, weeping or damage;(2) Cooling fins for signs of damage;(3) Check of electrical equipment's monitoring systems, including level or temperature gauges and alarms (if present);(4) Condition of trap rock or other containment or diversionary structures surrounding the electrical equipment; (5) Drain valves securely shut and drains plugged with pipe caps (where equipped);

and, (6) Presence of vegetation surrounding the electrical equipment, which could interfere with prompt inspection and response, as well as create a fire hazard.4. A semi-annual visual survey shall be conducted above the path of underground piping systems (from storage tank to receiving equipment) for signs of potential oil release. Signs of potential oil release are:* A change in the surface contour of the ground* Discoloration of the soil* Softening of paving asphalt* Pool formation-

• Bubbling water Puddles, or 4-1.16 NAEC Rev. 40 Noticeable odor (per API 570 Section 9. 1.1)5. A semi-annual inspection of the interstitial space between the inner and outer tank walls of double-walled tanks shall be performed for the presence of water or product. Tanks with interstitial monitoring are not subject to this inspection requirement.

Note: Currently, the. SEPS fuel oil tanks are the only double-walled tanks onsite that have interstitial monitoring systems; however, there are other double-wall tanks onsite, mainly portable fuel tanks, that will, require semi-annual inspection.

6. Annual testing (activation) of overfill and interstitial alarm sensors on specified tanks shall be performed.

1.6.7 Containers, Drums and Temporary Equipment Management Program 1. All 55 gallon drums issued from the warehouse shall have a blank label attached.Regardless of the drum contents all drums shall be labeled. The owner of the drum shall fill out the label. Refer to Figure 4-1-1, Best Management Practices for 55-Gallon Drums.2. Containers, drums and temporary equipment used for transfer and storage of oil and chemicals will be engineered to contain, and shall be compatible with, the materials being transferred / stored and the storage conditions.

3. Spill prevention/containment provisions shall be made for oil or chemicals stored in temporary equipment such as tanker trucks, fuel tanks, chemical tanks, etc., when located on site for periods greater than one shift. The provisions shall include one or more of the following:

• Secondary containment, i.e., dikes or berms lined with plastic.* Conduct surveillances at least once per shift (8 hours or 12 hours depending on schedule).

Isolation of nearby storm drains with covers, dikes or berms.4. Drums and containers, particularly those containing liquid, should be raised off the ground or floor (e.g., placed on pallets) regardless if within a bermed area.Refer to Figure 4-1-1, Best Management Practices for 55-Gallon Drums.5. Outdoor storage of any drum or container whether full, partially full or empty, that contains or previously contained oil, a regulated chemical, or hazardous substance with the anticipation of being stored outdoors for longer than one shift requires notification to Licensing for evaluation of location suitability and need for spill controls.6. Drums or containers stored outdoors shall not bestored within 50 feet of surface water. (NHDES Env-Wm 507.01(f)). 4-1.17 NAEC Rev. 40

7. Outdoor storage of regulated chemicals and oil in a container equal to or greater than five (5) gallons, for periods often (10) or more consecutive days must be evaluated on a case-by-case basis by Licensing to determine need for additional spill controls.These additional controls may include the following provisions:

Secondary containment structure with impervious surface adequate to contain any spills or leaks with sufficient freeboard to accommodate any collected storm water precipitation. (For oil tanker with multiple compartments, the secondary containment structure shall be adequate to contain the contents of the largest single compartment.) Weekly inspection of storage areas for signs of spills and/or leakage of regulated containers. Readily available spill control and containment equipment, including as a minimum, absorbents to pick up spills and leaks.Each container clearly and visibly (without need for the observer to rotate drum) labeled with the chemical and trade name of the material stored within.Nearby storm drains covered or blocked to prevent discharge of spill oil or chemicals.

8. Outdoor container storage inspection shall be conducted weekly. Inspection entails: (1) Condition of the containers for signs of wear or damage;(2) Condition of paint, coatings and welds along the bottom chime of the container (for corrosion);

(3) Position and location of container's cover, which should be secured unless adding or removing product;(4) Condition of all labels and markings;(5) Not stored in direct contact with the ground; and (6) Condition of all supports, racks, bracing and other structural elements used to secure the storage containers.

9. Visual inspection of applicable storage containers (i.e., 55-gallon drums or greater) stored indoors shall be done on a monthly basis.10. Portable containers such as 55-gallon drums or intermodal bulk containers are also subject to the testing requirements in 40 CFR 112.8(c)(6), as outlined in Section 1.6.6.b, Inspection and Test Requirements.

2.6.1 General

Spill Controls and Precautions for Chemical Storage and Usage Locations 1. Chemical-containing systems will be maintained in a secure manner such that only authorized personnel are allowed to operate valves, pumps, and transfer stations, in accordance with written station procedures.

2. Fill pipes, drain valves, caps and/or covers on outdoor chemical tanks, containers and drums shall be securely capped and/or secured in the closed position when not in use.3. Workers required to handle or use chemicals in areas having a direct pathway to the environment are to minimize the volume handled and use good housekeeping practices.

4. Chemical residues from equipment in use in areas having a direct pathway to the environment must be immediately contained or cleaned up with compatible absorbent materials.

5. Stationary chemical storage equipment cannot be installed in areas having a direct pathway to the environment unless protected by a berm of sufficient size to contain the maximum spill.4-2.5 NAEC Rev. 39

6. Temporary and portable chemical storage container/tanks are not permitted in areas having a direct pathway to the environment (wetlands, surface water, wells, property lines, flood zones, and drainage areas), unless at least one of the following occurs: NOTE On no account, shall any container containing, or has contained, Hazardous Waste be stored outdoors within 50 feet of such areas (a) The container is under the direct control of workers with constant awareness, and who could immediately respond to prevent a spill.Example: Leaving a 2.5 gallon pesticide container next to a stream or storm drain while spraying an area 100 yards away would not be considered under constant awareness because immediate response to prevent surface water pollution would not be possible.

However, leaving the container in an area far removed (>50 feet) from streams, storm drains or nearby wells would be acceptable provided additional common sense precautions are taken to ensure (1) the container is securely capped and placed in a manner that it will not tip over spilling its contents.onto the ground, (2) the worker is aware of its location and has reasonable expectations that the container will not be tampered with while left unattended, and (3) the container is not left unattended for longer than one working shift.(b) A spill would be detected under normal Station surveillances before release to the environment occurs, i.e., Operations has been notified of the location of the temporary container such that it would be surveilled during routine shiftly rounds.Note: A container left by a storm drain in the GOB parking lot would not qualify since Operations personnel do not normally surveil this area.( (c) Installing a temporary berm to provide secondary containment around the container or yard drains. A temporary berm can be in the form of oil absorbent pillows, oil "pigs" (sausages), sand, speedy dry, etc.Note: (1) The type of temporary berm selected/used must be appropriate for the application to ensure proper secondary'containment. Licensing should be contacted for guidance to ensure that the spill control measures are appropriate for the specific chemical application. 4-2.6 NAEC Rev. 39 (2) Temporary berms shall be periodically inspected and maintained as necessary, while deployed 7. Spill prevention/containment provisions shall be made for chemicals stored in temporary equipment such as tanker trucks, fuel tanks, chemical tanks, etc., when located on site for periods greater than one shift. The provisions shall include one or more of the following:

• Secondary containment, i.e., dikes or berms lined with plastic.* Conduct surveillances at least once per shift (8 hours or 12 hours depending on schedule).

Isolation of nearby storm drains with covers, dikes or berms.8. Drums and containers, particularly those containing liquid, should be raised off the ground or floor (e.g., placed on pallets) regardless if within a bermed area.Refer to NAEC Chapter 4, Section 1.0, Figure 4-1-1, Best Management Practices for 55-Gallon Drums.9. Outdoor storage of any drum or container whether full, partially full or empty, that contains or previously contained a regulated chemical or hazardous substance and will be stored outdoors for longer than one shift requires notification to Licensing for evaluation of location suitability and need for spill controls.10. Drums or containers stored outdoors shall not be stored within 50 feet of surface water. (NHDES Env-Wm 507.01(f)).

11. Outdoor storage of regulated chemicals in a container equal to or greater than five (5) gallons, for periods often (10) or more consecutive days must be evaluated on a case-by-case basis by Licensing to determine need for additional spill controls.These additional controls may include the following provisions:

Secondary containment structure with impervious surface adequate to contain any spills or leaks with sufficient freeboard to accommodate any collected storm water precipitation. (For tanker with multiple compartments, the secondary containment structure shall be adequate to contain the contents of the largest single compartment.) Weekly'inspection of storage areas for signs of spills and/or leakage of regulated containers. Readily available spill control and containment equipment, including as a minimum, absorbents to pick up spills and leaks.Each regulated container clearly and visibly labeled with the chemical and trade name of the material stored within.Nearby storm drains covered or blocked to prevent discharge of spill oil or chemicals.

12. Outdoor container storage inspection shall be conducted weekly. Inspection entails the following:

(1) Condition of the containers for signs of wear or damage;.4-2.7 NAEC Rev. 39 (2) Condition of paint, coatings and welds along the bottom chime of the container (for corrosion); (3) Position and location of container's cover, which should be secured unless adding or removing product;(4) Condition of all labels and markings;(5) Not stored in direct contact with the ground; and (6) Condition of all supports, racks, bracing and other structural elements used to secure the storage containers.

13. Visual inspection of storage containers (i.e., 55-gallon drums or greater) stored indoors, other than pesticides, herbicides, biocides, and hazardous wastes stored in designated 90-day hazardous waste storage areas, shall be done on a monthly basis.14. Tanks, containers and/or drums used for storage of pesticides, herbicides, biocides, and hazardous wastes stored in designated 90-day hazardous waste storage areas, are subject to weekly visual inspections.

15. Secondary containments are subject to monthly visual inspections (ref. NAEC Chapter 3, Section 4.9.2, Surveillance Requirements).

16. Whenever bulk transfers of chemicals are made, storm drains that may be impacted by a chemical spill shall be protected with covers, dikes or berms to preclude the discharge of these materials to the environment during transfers.

17. Station personnel should, particularly for non-routine evolutions, contact Licensing to conduct an assessment of specific spill prevention needs on a case-by-case basis to ensure effective chemical spill controls.

Evolutions such as routine chemical deliveries will not be subjected to prior review by Licensing provided such evolutions are controlled by specific station procedures.

18. During filling / transfer operations station personnel assigned to the transfer evolution shall* Block nearby storm drains (within 50 feet downgrade) as necessary,* Use available level indications to monitor the transfer,* Be in direct communication with the tank truck operator, and* Have the ability to stop the transfer in the event of a problem or spill.19. Whenever any type of chemical transfer will occur, supervisors

/ operators must be cognizant of the likelihood of fluctuating flow rate and potential problems associated with changing product temperature during the transfer.4-2.8 NAEC Rev. 39 Example: Tanker truck with cold fuel oil filling a heated stationary tank that is inservice supplying operating equipment, whereby temperature changes in tank contents, whether mixed or stratified, may cause inservice equipment to operate erratically or malfunction.

20. If tanker truck unloading is not governed by station procedures, the generalized unloading procedures in Attachment C of the SPCC Plan shall be used. -Licensing must approve any deviation from this guideline and may impose additional requirements.

21. The Contract Coordinator or department responsible for the evolution involving the flushing or transfer of chemical and hazardous substances will confirm prior to performing the evolution, that the environmental requirements in Attachment B of the SPCC Plan have been satisfied.

Note: To ensure compliance with applicable state and federal requirements, Licensing personnel may specify additional criteria. Any exceptions to the Attachment B criteria established for each evolution will be provided by Licensing and documented for inclusion in the work package.22. Prior to the performance of any non-routine evolution involving the flushing or transfer of chemical or other hazardous substances, an inspection of hoses and associated couplings must be performed and ensure spill prevention controls have been implemented. Attachment B of the SPCC Plan contains guidelines for hoses and associated couplings.

23. When using temporary equipment such as hoses, tanks and pumps, the department responsible for the evolutions involving the flushing or transfer of chemicals or hazardous substances must ensure the following:

Flushing / transfer evolutions are performed in accordance with approved written procedures incorporating the elements listed below, Assign a designated person-in-charge (PIC) with responsibility to oversee and instruct the start of the evolution, be immediately available should problems arise, and be physically present during coupling and uncoupling of hoses, Appropriate spill-containment measures have been instituted around hoses and temporary equipment, particularly in manifold and coupling/uncoupling areas, An inspection walkdown of equipment condition and hose layout has been performed prior to any flushing or transfer evolution, A satisfactory leak test of the installed flushing/transfer system at NOP/NOT is performed,* Pressure gauges indicate within 10 percent of actual working pressure,* Adequate lighting is available to illuminate areas, particularly where couplings are located, when transfer operation is in progress, 4-2.9 NAEC Rev. 39 When transferring flammable products, consideration for use of"Intrinsically Safe" portable radios, certified by a USCG-recognized lab or certifying organization. Certification documentation should be retained for USCG inspection. If intrinsically safe radios are not available, a safe distance (i.e., out of the plume) should be maintained away from flammable or potentially explosive products when using non-intrinsically safe radios.* Spill response trailer or other appropriate spill equipment at job location,* All requirements established by Licensing have been met, and*

• Written confirmation and/or copies of test certification have been obtained from the vendor verifying that the hose and coupling criteria (as specified in Attachment B of the SPCC Plan) have been met.Note: Hose assembly end connections other than that specified in Attachment B of the SPCC Plan will be considered on a case-by-case basis by Licensing.

24. Consideration shall be given to minimizing the number of hose sections required.Licensing may reject applications that have an unreasonable number of coupled connections.

25. Per USCG Specification in Title 33, Chapter 1, Paragraph 154.500, hose assemblies used for transferring petroleum or hazardous material products must be subjected to an annual static pressure test by the vendor to at least 1.5 times the rated working pressure.2.6.2 Administrative Controls for Extremely Toxic or Flammable Materials Under the provisions of the Clean Air Act, Section 112(r), the EPA has identified 77 extremely toxic and 63 extremely flammable materials that pose exceptional risk to the public and the environment when present in excess of specified threshold quantities (see Appendix C, Table 1).When present in excess of the specified threshold in a process, the facility is required to develop and submit to the EPA a formal risk management program. For those listed materials in use on site, the following administrative controls have been established to maintain site inventories below the regulatory threshold limits which mandate the development and implementation of a formal risk management plan.Chemical Name Threshold Quantity (lbs.)

1.0 NONRADIOLOGICAL

ENVIRONMENTAL IMPACT REVIEW 1.1 Background The Nonradiological Environmental Impact Review process described in this chapter is designed to satisfy the requirements of both Seabrook Station's Operating License and the NextEra Energy Seabrook Environmental Policy.Appendix B to the Facility Operating License contains the Nonradiological Environmental Protection Plan (EPP). This part of Seabrook Station's operating license requires that changes in Station design or operation and the performance of tests or experiments be reviewed to ensure they do not involve an unreviewed environmental question (UEQ). A change or test that involves a UEQ is one that has the potential to have a significant adverse environmental impact that has neither been analyzed nor enveloped by existing analyses reviewed and approved by the NRC as part of the licensing process. Activities that do not affect the environment are not subject to these requirements nor are changes and tests that are required to achieve compliance with other Federal, State, and local environmental regulations. The NextEra Energy Seabrook Environmental Policy (see NAEC Figure 1-1-1) requires programs and standards that will, in part, ensure that activities potentially affecting the environment are evaluated, mitigated, and documented in a timely manner. The policy also states that changes in Station design or operation shall be reviewed to ensure that they fulfill the Environmental Policy environmental stewardship philosophy and Station Environmental Compliance Program requirements. To meet both the letter of the licensing requirement and the spirit of the company's Environmental Policy, the Nonradiological Environmental Impact Review process will provide a mechanism for evaluating changes and activities that have the potential to affect the environment and a means to minimize and measure the effect of Station operations. The Nonradiological Environmental Impact Review will ensure that the change or activity is thoroughly reviewed,. required notifications are made, and approvals received to ensure the requirements of Appendix B and the Environmental Policy objectives-are met.Station changes to design and procedures undergo formal review processes in accordance with the MINPR, NADC, and SSMA. The Nonradiological Environmental Impact Review process ensures that these Station changes that undergo a formal review process are also screened for nonradiological environmental impact at the same time. It also notifies Licensing when a final review of environmental impact is necessary. The Environmental Impact Review will start with a Nonradiological Environmental Impact Screening using the guidance contained in this chapter.The purpose of the environmental screening is to determine if the change or activity has the potential to have a significant environmental impact. If the change or activity is determined to have such potential, Licensing personnel will perform the final review and determine if an unreviewed environmental question exists.5-1.1 NAEC Rev. 40 Activities governed under the Work Control process will be screened for environmental impact by work request evaluators and planners in NAMS Work Management. Activities not governed by specific NextEra Energy Seabrook programs, such as those performed by the Facilities and Site Support Department, will be periodically reviewed for significant environmental impact by the Licensing Department. Environmental awareness training of site personnel will provide knowledge to individuals to ensure environmental concerns are addressed during daily work activities. The formal documentation for environmental impact screening for Station changes that undergo screening in accordance with the documented review processes governed by the MNPR, NADC, and SSMA satisfies the requirements of Appendix B to the Operating License. Formal documentation for environmental impact screening of Station changes that do not otherwise require a formal review process is not required. The intent of the NextEra Energy Seabrook Environmental Policy will be met in these instances by environmental awareness training and monitoring by the Licensing Department.

1.2 Purpose

This section contains the requirements for preparing, reviewing and approving environmental evaluations in conjunction with the formal review processes screenings associated with a.

1.0 Cultural

Resources Protection Plan* 1.1 Background The National Historic Preservation Act (NHPA) requires federal agencies to consider affects on archaeologically and historically significant cultural resources prior to issuing a permit or license or amendment thereto. NextEra Seabrook is licensed by the Nuclear Regulatory Commission (NRC) to operate Seabrook Station. As a result, ground disturbing activities requiring prior approval by the NRC may be subject-to NHPA consultation. The vast majority of ground disturbing activities at Seabrook Station which could impact archaeological, cultural and/or historic resources do not require prior NRC approval and so would not be a federal undertaking subject to NHPA requirements. Nevertheless NextEra Seabrook will voluntarily assess these undertakings to assure the protection of archaeologically and historically significant cultural resources. To meet this commitment NextErahas de'-elbped this Cultural Resource Protection Plan (CRPP).1.2 Purpose .The purpose of this plan is to assist the mission of the New Hampshire Division of Historical Resources (NHDHR) as New Hampshire's State Historic Preservation Office (SHPO). The legislature of New Hampshire has determined that the historical, archeological, architectural, engineering, and cultural heritage of New Hampshire is among the most important environmental assets of the state and that the rapid social and economic development of contemporary society threatens the remaining vestiges of this heritage; therefore, it is public policy and in the public W interest of the state to engage in a comprehensive program of historic preservation to promote the use and conservation of such property for the education, inspiration, pleasure, and enrichment of the citizens of New Hampshire. (RSA 227-C)There are seven Native American archaeological sites present on the Station property and recorded with the State of New Hampshire: Healy's Island (27 RK 162), South Rock Storage Area (27 RK 170),. Bolian # 2 (27 RK 452), Rock's Road (27 RK 75), Bolian #5 (27 RK 453), Hunt's Island (27 RK 164) and Seabrook Marsh (27 RK 165). In addition, several areas have been identified as having high site potential for the presence of Native American archaeological sites. As of the time of the writing of this plan, no development had been proposed within these areas. Thus, no impact to identified sites and areas of high site potential has occurred. Both the seven identified sites and the areas of high site potential should be avoided by any future construction. If future, proposed construction cannot avoid these areas, then archaeological investigation should be undertaken in advance of the proposed construction. This plan describes the actions NextEra has taken and will take to enhance the protection of archaeological, cultural and historic resources at Seabrook Station 1.3 Applicability, This plan _is .applicable to' land disturbing activities within the Owner Controlled Area; but outside the Protected Area. Areas indentified as archeologically':sensitive and areas known to contain archeological sites are documented in Cultural Resources Management Plan, Seabrook Nuclear Power Plant contained in Appendix G. (See specifically Figures 4, and 5-F thru %7N.)

It is also not applicable to the cutting of asphalt or routine grading of ground.This procedure applies to all activities within the scope of the procedure within the owner-controlled area.Land disturbing activities planned within areas containing or potentially containing archaeological, cultural or historic resources as identified in the Cultural Resources Management Plan, Seabrook Nuclear Power Plant will be surveyed by a state approved archaeologist prior to initiating grounddisturbing activities.

NextEra Seabrook will forward completed surveys to the New Hampshire Division of Historic Resources Refer to the Environmental Compliance Manual procedure 6-1.4.0 INSTRUCTIONS

4.1 Definitions

1. Competent Person -.A person who has documented specific training in OSHA trenching applications and rules. A Competent Person is capable of identifying existing and predictable hazards in the surroundings, or working conditions that are unsanitary, hazardous or dangerous to workers. The Competent Person is authorized to stop work and initiate prompt corrective measures to eliminate those conditions.

SH 6.4 Page 5 Rev. 12 2. Excavation -Any man-made cut, cavity, trench, or depression in an earth surface formed by earth removal. For the purposes of this procedure vacuuming, drilling, driving, digging, augering, and trenching are considered excavations.

3. Protective system -A means of protecting workers from cave-ins, from material that could fall or roll from an excavation face or into an excavation, or from the collapse of adjacent structures.

Protective systems include support.systems, sloping and benching systems, shield systems, and other systems that provide necessary protection.

4. Registered professional engineer -A person registered as a professional engineer in the state where work is performed.

5. Shielding (shield system) -A structure able to withstand the forces imposed on it by a cave-in, thereby protecting workers within the structure.

Shields can be permanent or portable structures that are moved along as work progresses. Shields used in trenches are usually referred to as trench boxes or trench shields.6. Shoring (shoring system) -A structure (e.g., metal hydraulic, mechanical, or timber) that supports the sides of an excavation and is designed to prevent cave-ins.7. Sloping (sloping system) -Excavations with sides inclined away from the excavation to prevent cave-ins. The angle of incline required to prevent cave-in varies with differences in such factors as the soil-type, environmental conditions of exposure, and application of surcharge loads.8. Trench -A narrow (in relation to its length) excavation made below the surface of the ground. In general the depth is greater than the width, but the width measured at the bottom does not exceed 15 feet. If forms or other structures are installed or constructed in an excavation so as to reduce the dimension measured from the forms or structure to the side of the excavation to 15 feet or less, the excavationis also considered to be a trench.9. Vacuum Excavation -The use ofjets of air or water to loosen soil which is then picked up through a vacuum hose. Typically used for utility location.4.2 Responsibilities

SH 6.4 Page 22 Rev. 12* Figure 5.3 Limitations of Electronic Equipment*The following limitations of electronic survey equipment should be considered during performance of all dig safe ground surveys: Ground Penetrating Radar (GPR)'Signal penetration is site specific and is determined by dielectric properties of the soil or fill materials. o Obj ects deeper than the signal's maximum penetration depth remains undetected. Interpretations are subjective and are based on identifying reflection patterns that may not uniquely represent a subsurface obj ect.Varying an antenna's speed along a survey traverse can cause slight errors in horizontal distance interpolations and inferred object positions. GPR is most likely to detect concrete or metallic objects with the exception of metallic objects located under reinforced concrete because the signal couples onto the metal rebar and mesh in the concrete, and the signal on a particular metallic object cannot then be traced with any reliability. Plastic or vitreous clay pipes, or Fiberglas objects are unlikely to be detected.o Small diameter objects may be difficult to detect unless they are quite shallow (less than 1.5 feet).a Closely spaced pipe may produce reflections that resemble a single object..* If two pipes occupy the same trench at different depths, only the shallower pipe may be detected.Metal Detector* A change in ground mineral conditions can give a visual indication.

• It is possible to get a null reading if directly over a source.

The job briefing is a forum that provides an opportunity for workers and supervisors to identify, discuss, and mitigate potential job hazards, discover human error traps and promotes the exchange of ideas and experience.

CR# 05-15106 was the most recently generated condition report pertaining to an excavation related event at Seabrook Station. As indicated above in the "Reference" section, there have been numerous documented occurrences associated with excavation related activities since 2002.Why is this significant? Subsurface excavation activities creates significant potential hazards to personnel and the operating equipment/components that support the safe effective operation of Seabrook Station. Due to site-specific, as well as industry events that resulted from excavation and/or trenching activities, administrative and technical controls have been established to ensure that underground obstructions or commodities are not unexpectedly encountered. The specific requirements for working within trenches and/or excavations, or performing other digging, drilling, or pile driving activities that are done by machine that penetrates the plane of the ground surface, as well as excavations performed by hand that exceed a depth of 12" below grade, are contained in this procedure (NASH, procedure SH 6.4). SH 6.4 Page 24 Rev. 12 Figure 5.4 Excavation Pre-Job Briefing Considerations (Sheet 2 of 3)What do I need to consider?o SH 6.4 is the governing document and shall be used for all excavation-related activities at Seabrook Station.o The Nuclear Projects Manager, 6r'designee, is responsible for approving Dig. Safe Permits (form SHf 6.4A).* The Work Group Supervisor is responsible for ensuring that personnel performing work within the scope of SH 6.4 are qualified prior to initiating work activities, and understand and comply with the requirements set forth in SH 6.4.o A subsurface scan shall be completed by an approved geotechnical surveying service, and the result will be reviewed prior to Dig Safe Permit approval.o Consider vacuum excavation to locate services before major work.* If required, a qualified "competent person" shall be designated to support the excavation/trenching activity, in accordance with SH 6.4, §4.2.3.o A copy of the Dig Safe permit shall be posted at the work site at all times until the excavation activities are completed. o A Work Order will be the implementing document for any excavation activities at Seabrook Station.* e Any change in condition or work scope will not be implemented prior to the Dig Safe permit being revised to reflect the change, as well as a scope change being generated for the implementing Work Order.a All subsurface components are to be considered permanent and energized regardless of belief, and are not to be physically altered, modified, or removed without approved documentation.

• A dedicated safety spotter will be assigned for excavation/digging activities that requires mechanical equipment, when being operated directly adjacent to, or having the potential to come into contact with, operating structures, systems, or components (SSC).o Upon discovery of an unexpected or unwanted condition, workers are to immediately STOP and notify supervisory personnel so the condition can be assessed.

If unexpected archaeological, cultural or historic resources during any ground disturbing activity the activity will be stopped and the New Hampshire Division of Historic Resources will be consulted prior to recommencing work. If these resources include human remains the area will be secured, Security and Control Room notified and the Seabrook Police shall be called immediately to determine the need for criminal investigation. 0 Whether expected or unexpected, when an underground commodity is struck, the work shall be immediately stopped and the equipment placed in a safe condition. Work may not be restarted without approval of the Nuclear Projects Manager.o Following any occurrence of an excavation-related (Dig Safe) event, work can recommence only: following approval by the Nuclear Projects Manager.What else should I consider every day before I begin work?All personnel will STOP when unsure and obtain supervisory guidance for resolution. SH 6.4 Page 25 Rev. 12 Figure 5.4 Excavation Pre-Job Briefing Considerations (Sheet 3 of 3).The use of Human Performance Tools (STAR, Self-Checking, Peer Checking, 3-Way Communication, QV&V, STOP When Unsure) and the 5 Activity Preview Questions shall be covered every day during each Pre Job Briefing prior to initiating work activities.

• Work documentation will be prepared and approved prior to implementation of any work activity.* Work Order documentation is to be maintained current on a daily basis -" All permits are to be reviewed daily to ensure they are appropriate for the existing conditions." PPE will be donned at all times in accordance with the posted or communicated requirements." Action requests will be generated for any unwanted/unexpected situation or result.
