Enclosure SPDES Permit Modification Request

Nine Mile Point Nuclear Station, LLC "SPDESPermit #NY0001015 SPDES Permit Modification Request The first nine (9) items addressed in this modification request are items set forth in the New York State Department of Environmental Conservation (NYSDEC) letter dated July 2, 2001, from Mr.

William McCarthy (Attachment 1). The remaining items are administrative/editorial or minor modifications to the SPDES permit. A mark-up of the current State Pollutant Discharge Elimination System (SPDES) Permit with the proposed changes is included as Attachment 2. A list of all attachments is included at the end of this request.

1. Issue: Additional designation of the new chemical unloading station drain. [ref.

Attachment 1, Item 1]

Discussion: A concrete containment pad has been constructed to satisfy hazardous chemical unloading containment requirements pursuant to 6 NYCRR Part 598. The containment pad drains to the adjacent gravel area via a "mud" valve. The drain valve is closed when a delivery vehicle is transferring chemicals to the facility's storage tanks within the Unit 2 screen house, or if a product-containing vehicle is temporarily stored within the containment. If precipitation waters accumulate when this valve is in the closed position, and no chemical product has spilled within the containment structure, these uncontaminated precipitation waters are discharged to the adjacent stones upon the removal of the delivery vehicle. The drain valve is normally maintained in the open position to allow drainage when the containment structure is vacant of delivery vehicles.

If a spill did occur during a product transfer, the containment structure would provide the necessary spill protection to comply with 6 NYCRR Part 598, and the spill would be managed per NMPNS spill procedures and the Spill Prevention Report (SPR).

Other structures on site, e.g., structures containing oil-filled electrical equipment, perform similar functions and are subject to the same drainage criteria.

Request: Based on the above information, add a footnote to Outfalls 001, 002 and 020 that allows the discharge of uncontaminated storm water from containment structures to the surrounding grounds/Outfalls (Outfall 001,002 and 020).

The suggested language for the footnote is in Attachment 3, footnote 'q'.

2. Issue: Clarification of permit language for Outfall 007, 'Floor and Equipment Drains'

[ref. Attachment 1, Item 2]. This is interpreted as identification of the contributing floor and equipment drains to Outfall 007.

Page I of 13

Nine Mile Point Nuclear Station, LLC SPDES Permit #NY0001015 SPDES Permit Modification Request

2. (Continued)

Discussion: Outfall 007 actually has seven identified contributing sources, as follows:

007 - Floor and equipment drains 007A - Manhole #110, Unit 2 Chiller Building 007B - Unit 1, Administration, Sump 1 007C - Unit 2, Service Water, 2DFM - Sump 2B 007D - Unit 2, Service Water, 2DFM - Sump 2A 007E - Unit 2, Control Building, 2DFM - Sump 4 007F - Manhole #103, Unit 2 Screen House - West 007G - Manhole #207, Unit 2 Screen House - North Request: Identify specific drains 007A through 007G on the permit monitoring location schematic as the contributing sources to Outfall 007. The permit monitoring location schematic is Attachment 2 in the permit (page 11 of 17 of the current permit).

The existing permit parameters and limitations for the current Outfall 007 will apply to these newly designated locations. A proposed modification to the schematic is included as Attachment 10 to this application.

3. Issue: Permit footnote for adjoining sumps at Outfall 040A, 'Circulating Water Pumps Area Sumps' [ref. Attachment 1, Item 3].

Discussion: Unit 2 has two circulating water pump (CWP) pits, each of which has a separate sump that discharges via Outfall 040A to Outfall 040, 'Cooling Tower Blowdown and Service Water'. The sumps are not specifically identified in the permit.

Request: Add a footnote to Outfall 040A that specifically identifies the CWP pit sumps as contributing sources to Outfall 040A.

The suggested language for the footnote is in Attachment 3, footnote 'r'.

4. Issue: Deletion of Outfall 022, 'Security Building Air Conditioning' [ref. Attachment 1, Item 4].

Discussion: The Unit 1 Security Building air conditioner condensation currently discharges to the on-site Wastewater Treatment Plant (Outfall 030) in accordance with footnote 'h' of the existing SPDES permit. Outfall 022 is also designated as an approved discharge location for this air conditioning condensation, but NMPNS has not used Outfall 022 as a discharge point in over five years. Furthermore, the existing permit allows for the discharge of air conditioning condensation via the Unit 1 storm drain system (Outfall 020).

Nine Mile Point Nuclear Station, LLC SPDES Permit #NY0001015 SPDES Permit Modification Request

4. (Continued)

Request: Remove Outfall 022 from the SPDES permit based on the information provided above. In addition, add footnote (h) to Outfall 030.

5. Issue: Reporting of a calculated value for copper at Outfall 040, 'Cooling Tower Blowdown and Service Water' [ref. Attachment 1, Item 5]. In particular, specify the calculation equation and parameters used in this determination.

Discussion: Permit footnote 'g' for Outfall 040 states that "the total copper concentration for Outfall 040 will be based on a calculated value taking into consideration the flow from the service water system". However, the specific equation and parameters used in the calculation are not identified in the permit.

The following equation is used for the calculated copper value for Outfall 040 to satisfy footnote 'g' of the facility's SPDES permit.

Total copper concentration at Outfall 040 =

[CWS]cu x CWS Blowdown Flow [CWS]*c x Tempering Flow

+

Total Flow for Outfall 040 Total Flow for Outfall 040 Where:

[CWS]cu =Copper concentration of Circulating Water System (CWS) Blowdown Total Flow for Outfall 040 = CWS Blowdown Flow & Service Water Discharge Flow Tempering Flow = The amount of service water (discharge effluent) used to temper the service water influent during winter months Request: Modify footnote 'g' to include the above equation and parameters for the calculation of the copper concentration at Outfall 040. The full, modified text of footnote

'g' is included in Attachment 3, footnote 'g'.

6. Issue: Discharge of transformer containment to an identified outfall [ref. Attachment 1, Item 6].

Page 3 of 13

Nine Mile Point Nuclear Station, LLC SPDES Permit #NY0001015 SPDES Permit Modification Request

6. (Continued)

Discussion: There are several secondary containment systems on site for oil-containing electrical equipment, primarily transformers. The containment structures must be periodically drained of precipitation water in order to maintain required containment capacity. This water is routinely uncontaminated, but is visually inspected prior to each drain event. Each inspection and draining is performed in accordance with the facility's Spill Prevention, Control and Countermeasure (SPCC) plan, which conforms to 40 CFR Part 112. When drained, these waters are discharged to the surrounding ground surface.

Request: Apply the proposed footnote listed in Item 1 of this modification request (see proposed footnote 'q' in Attachment 3) to address the discharge of uncontaminated storm water from various structures. The footnote should be generally applied to similar on-site structures that may accumulate storm water, provided inspections are performed prior to draining.

7. Issue: Modification of Outfall 026, 'Unit #2 Resin Regeneration, Demineralized Test Water, and Reverse Osmosis Wastewater' [ref. Attachment 1, Item 7]. Although potential deletion of the outfall is identified in Attachment 1, only flexibility in directing Outfall 026 is at issue.

Discussion: Outfall 026 is designated for Unit #2 resin regeneration wastewater, demineralized test water and reverse osmosis water. This outfall currently discharges to the Wastewater Treatment Plant (Outfall 030). However, the original plant design configuration was engineered to also allow these flows to discharge via Outfall 040,

'Cooling Tower Blowdown and Service Water' or Outfall 030, 'Wastewater Treatment Plant'. The original SPDES Permit was permitted to allow this outfall to discharge via Outfall 040.

Allowing the flexibility to discharge Outfall 026 to Outfall 040 would relieve the Wastewater Treatment Plant (Outfall 030) of a hydraulic loading of "clean" waters. The waters that discharge from Outfall 026 are primarily demineralized waters.

Request: Modify the permit monitoring location schematic (Attachment 2, page 11 of 17, in the permit) to allow Outfall 026 to discharge to Outfall 040 in addition to the currently permitted discharge to the Wastewater Treatment Plant (Outfall 030), i.e., either discharge location would be acceptable. When discharging to Outfall 040, effluent parameters of flow, pH and oil and grease would apply with quarterly monitoring requirements. The current discharge effluent parameter of flow would remain when discharging to Outfall 030. Attachment 10 of this modification is a revised monitoring location schematic incorporating these changes.

8. Issue: Clarification of the frequency of flow monitoring for Outfall 010, 'Condenser Cooling Water Unit 1' [ref. Attachment 1,Item 8].

Discussion: NMPNS calculates Outfall 010 flow using pump curve data and lake level data. The lake level is obtained from the pressure reading on the "Adams Strainer", which is proportional to lake level. Personnel that take the readings are only available during normal working hours (Monday through Friday) for recording this data. Since the personnel that take the lake level reading are not available on weekends and holidays, the lake level data from the previous surveillance is used in calculating flows for weekends and holidays.

Request: Based on the above, add a footnote to Outfall 010 that specifies the parameters and frequency for obtaining data to calculate the condenser cooling water flow rate. Suggested wording is included as footnote 's' in Attachment 3.

9. Issue: The revision and/or clarification of footnote 'a' on page 5 of 17 of the SPDES permit regarding the temperature differential conditions for reverse flow conditions and plant safety conditions during emergencies [ref. Attachment 1, Item 9].

Discussion: Unit #1 occasionally needs to reverse flow for its condenser cooling water in order to de-ice its intake structures. The permit allows an intake-discharge temperature difference of 35 0F that per footnote 'a' may be exceeded by 35% (an additional 12.25"F, or 47.250 F total) for no more than one hour during each reverse flow or return to normal flow operation. However, a momentary increase above the 47.25°F value takes place during the initial change from reverse flow back to normal flow. This occurs because at the point of changing back to normal flow from reverse flow, already warmed water in the intake tunnel that has discharged from the condenser becomes the inlet water to the condenser. This water is further warmed as it passes through the condenser for a second time. When it discharges the condenser, it is being compared to cold lake water that is now the condenser inlet water. This temporary situation results in a temperature spike until the above normal temperature water is removed from the discharge tunnel. This temperature situation lasts for no more than fifteen (15) minutes.

Request: Modify footnote 'a' to allow a temporary exceedance of the 35% criteria when returning from reverse flow to normal flow operation. The period should be limited to 15 minutes. Suggested wording to modify footnote 'a' is included in Attachment 3.

10. Issue: Outfall 020, 'Storm Drainage Unit #1, Perimeter Drains and Condensation Water', currently has a requirement to monitor flow with no discharge limitation.

Page 5 of 13

Nine Mile Point Nuclear Station, LLC SPDES Permit #NY0001015 SPDES Permit Modification Request

10. (Continued)

Discussion: Currently, the facility calculates the flow based on precipitation because the outfall does not have a flow weir. Installation of a flow weir, or some other flow measurement device, at the discharge would be extremely difficult to maintain and keep operational due to wave and ice action from Lake Ontario. Additionally, it is NMPNS's position that the flow parameter does not provide the public with any useful data.

Request: Remove the flow parameter for this outfall. If the parameter is not removed, the analysis frequency should be changed to monthly since this is a continuous, not batch, discharge.

11. Issue: The removal of Inhibitor AZ8103 from Outfall 040, 'Cooling Tower Blowdown and Service Water (Unit #2)', and the addition of CUPROSTAT PF and Inhibitor AZ8104.

Discussion: Inhibitor AZ8103 is no longer in production by the supplier and therefore no longer used at the facility. The recommended substitute for this product is either Inhibitor AZ8104 or CUPROSTAT PF. NMPNS received NYSDEC approval for use of these products on September 28, 2001, from the NYSDEC Division of Water. [ref.

Attachments 5 and 6].

Request: Add Inhibitor AZ8104 and CUPROSTAT PF to Outfall 040. The discharge limit for Inhibitor AZ8104 should be 8.8 mg/1 and for CUPROSTAT PF should be 19.5 mg/1 [see Attachment 4]. In addition, footnote 'o' should be modified accordingly.

Suggested modification wording for footnote is included in Attachment 3.

Correspondingly, delete Inhibitor AZ8103 from Outfall 40 parameters.

12. Issue: Outfall 025, 'Unit #2 Cooling Tower Emergency Overflow', copper discharge limit.

Discussion: When Outfall 025 discharges, there is a high probability that the facility will exceed the copper limit at this discharge location point. Based on the permit, the discharge limitation for copper is 0.25 mg/l at the lake discharge. The copper concentration at the lake discharge is calculated in accordance with footnote 'g'. Due to dilution effects, the copper concentration in the cooling tower basin can be as high as 1.0 mg/l and still meet the 0.25 mg/l discharge limit to the lake. Historically the concentration of copper in the cooling tower basin is maintained below 0.3 mg/1 with the use of corrosion inhibitors.

Nine Mile Point Nuclear Station, LLC SPDES Permit #NY0001015 SPDES Permit Modification Request

12. (Continued)

An overflow event occurs very infrequently (less than once per year), and the discharge is expected to be less than one hour duration for the event. An overflow condition has not occurred since February 1995. When the event occurs, the basin overflows to a storm water ditch that ultimately discharges to Lake Ontario approximately one half mile down stream of the overflow point without the benefit of any significant dilution.

By raising the limit, the limit will be consistent with the concentration maintained in the basin for normal operation and NMPNS will be able to meet the limitation in the event of an Emergency Overflow with insignificant environmental impact.

Request: Raise the copper limit for Outfall 025 to 1.0 mg/l.

13. Issue: The designation of footnote 'I' on Page 5 of 17 of the SPDES permit.

Discussion: Footnote 'i' is incorrectly typed as an '1' in the permit. This is merely a typographical error.

Request: Correct the designation for footnote (i) on page 5 of 17 to a lower case letter 'I' instead of a upper case letter '1'.

14. Issue: The removal of Betz ClamTrol (whole product) and CT-1 parameters and discharge limitation from page 6 of 17 of the facility's permit.

Discussion: Betz ClamTrol and CT-1 are currently listed as parameters for Outfalls 010, 'Condenser Cooling Water Unit #1', and 040, Cooling Tower Blowdown and Service Water' on page 6 of 17 of the permit. However, these products are no longer available for use.

Request: Remove the reference to Betz ClamTrol (whole product) and the CT-1 parameter and discharge limitations for Outfalls 010 and 040 in the permit. The Discharge Monitoring Report (DMR) line item for this product should also be removed.

15. Issue: Modification of the sampling frequency for Spectrus CT1300 and Calgon H 130M at Outfalls 010, 'Condenser Cooling Water Unit #1', and 040, Cooling Tower Blowdown and Service Water' on page 6 of 17 of the permit.

Page 7 of 13

Nine Mile Point Nuclear Station, LLC SPDES Permit #NY0001015 SPDES Permit Modification Request

15. (Continued)

Discussion: Spectrus CT 1300 and Calgon H-130M are currently approved for use for the zebra mussel control program. During treatment, grab samples are required at intervals not to exceed 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. However, zebra mussel treatments using EVAC, which is used more often, require sampling at 8-hour intervals. Sampling at 8-hour intervals provides adequate control and protection of the environment, as demonstrated by controls implemented during EVAC treatments.

Request: Reduce the sampling frequency for Spectrus CT 1300 and Calgon H 130M from 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> to 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, consistent with EVAC sampling requirements.

16. Issue: Relief from the 60 day reporting requirement when using Calgon EVAC product, as listed on page 7 of 17 of the permit.

Discussion: Special Condition No. 6 for EVAC zebra mussel treatments requires that reports describing the results of the effectiveness of the zebra mussel control program and the effluent analyses for Calgon EVAC be submitted to the NYSDEC within 60 days following each chemical treatment. However, for similar treatments using Betz products, reports on the zebra mussel program are only required annually [ref. Special Condition No. 6 for Betz products, permit page 6 of 17]. Annual reporting for EVAC applications would provide similar control and review and would be consistent with the Betz zebra mussel control program reporting requirements.

Request: Modify the 60-day reporting requirement in Special Condition No. 6 on page 7 of 17. Instead require submittal of one annual report that reports on all EVAC treatments performed during the previous calendar year, with submission by March 1 St of each year.

17. Issue: Discharge location for Outfall 001A, 'Decay Heat Cooling Tower Blowdown'.

Discussion: The decay heat cooling tower uses city water as the system's makeup water source. The concentration of free available chlorine in city water was recently analyzed at 0.59 mg/l (3/30/02). During the cooler months (i.e., December to March) the evaporation rate and the biological demand within the system are very low. Because of this, the concentration of free available chorine in the system may exceed the SPDES limitation of 0.2 mg/l for total residual chlorine. An alternate water source is not readily available.

Request: Redirect the blowdown flow from the decay heat cooling tower to Outfall 040, 'Cooling Tower Blowdown and Service Water (Unit #2)'. The total residual chlorine will be monitored at the discharge of Outfall 040. The suggested language for the footnote is in Attachment 3, footnote 'u'.

Page 8 of 13

Nine Mile Point Nuclear Station, LLC SPDES Permit #NY0001015 SPDES Permit Modification Request

18. Issue: Discharge of storm water from cable/electric conduit structures.

Discussion: The Unit 2 switchyard contains underground cable/electrical conduit structures that may accumulate storm water. There is no inherent source of contamination in these structures. The accumulated water is discharged to the ground.

Discharge of storm water from these structures is essentially similar to handling of storm water in outdoor secondary containment structures, except that there is no contaminant source in the conduit structures. Therefore, discharge of storm water from these structures to the adjoining ground should be acceptable.

Request: The suggested footnote listed in Item 1 of this modification request addresses the issue of discharges of uncontaminated waters from various structures. This footnote (footnote 'q' in Attachment 3) should be generally applied to similar on-site structures subject to storm water and/or groundwater accumulation, including underground cable/electrical conduit structures.

19. Issue: Correction of the DMR for Outfall 041, 'Unit #2 Wastewater'.

Discussion: The monitoring frequency and sample type currently listed for Outfall 041 in the DMR are listed as 'Continuous, Recorder', which is incorrect. The SPDES permit actually requires the specific conductance to have a measuring frequency of each batch with a sample type of grab. [ref. Attachment 7]

Request: Change the DMR reporting criteria for Outfall 041 to once per batch with a sample type of grab.

20. Issue: Action Level requirements for Outfall 011, ' Unit #1 Wastewater' and Outfall 041, 'Unit #2 Wastewater'.

Discussion: Outfall 011 and 041 Action Level Requirements, page 9 of 17 of the SPDES Permit, require the facility to monitor these outfalls for phenolics. Review of the past 4 years of monitoring data indicates that the concentrations of phenolics for both outfalls have been below the detection limit of 0.1 mg/l, compared to an action level of 1.0 mg/l. [ref. Attachment 8]

It is NMPNS's position that further monitoring for phenolics will not provide the public with any useful data. The analytical/operational history indicates that continued monitoring is no longer warranted.

Request: Remove the action level requirement for phenolics from Outfalls 011 and 041.

Page 9 of 13

Nine Mile Point Nuclear Station, LLC SPDES Permit #NY0001015 SPDES Permit Modification Request

21. Issue: Removal of definitions in the SPDES Permit.

Discussion: The current SPDES Permit includes definitions for daily average and daily maximum [permit page 11 of 17]. The recent revision of the Discharge Monitoring Manual provides the definition of these terms. Maintaining definitions within the permit

21. (Continued) is duplicative.

Request: Remove definitions of daily average and daily maximum (SPDES Permit page 11 of 17) from the permit.

22. Issue: Use of barley straw for pH control in Outfall 023, 'Unit 1 Oil Retention Basin'.

Discussion: Precipitation from the Unit #1 switch yard collects in the oil retention basin, which discharges via Outfall 023. During the summer months the pH in the basin exceeds the SPDES permit limitation of 9.0 due to the growth of algae. The practice of using barley straw to control pH in this type of environment has proven to be very effective.

Request: Add a footnote to Outfall 023 allowing the use of barley straw to control pH in the basin. Suggested language is included in Attachment 3 as footnote 't'.

23. Issue: Action Level requirements for Outfall 007, ' Floor and Equipment Drains'.

Discussion: Outfall 007 collects uncontaminated water from floor and equipment drains. The Action Level Requirements for this outfall (page 9 of 17) require the facility to monitor this outfall for aluminum, barium, manganese and zinc. Review of the past 4 years of monitoring data indicates that the concentrations of barium and manganese have not exceeded 13% of their respective action levels during the period (<0.2mg/l Ba vs. an action level of 1.5 mg/l and <0.1 mg/l Mn vs. an action level of 1.0 mg/l). [ref.

Attachment 8]

It is NMPNS's position that further monitoring for barium and manganese will not provide the public with any useful data. The analytical/operational history indicates that continued monitoring for barium and manganese is no longer warranted.

Request: Remove the action level requirements for barium and manganese from Outfall 007.

24. Issue: Action Level requirements for Outfall 020, 'Storm Drainage Unit #1, Perimeter Drains, Condensation Water'.

Discussion: Outfall 020 collects uncontaminated storm water drainage from Unit #1.

Action Level Requirements, page 9 of 17 of the permit, require the facility to monitor this outfall for zinc and aluminum. Review of the last 4 years of monitoring data indicates that the maximum zinc concentration during the period has been less than 22% of the action level (<0.1 mg/I vs. action level of 0.45 mg/I) and is routinely at a much lower level. Aluminum concentrations have not exceeded 60% of the action level (0.3 mg/l vs.

action level of 0.5 mg/I) and are routinely well under 10% of the action level. [ref.

Attachment 8]

It is NMPNS's position that further monitoring for zinc and aluminum will not provide the public with any useful data. The analytical/operational history indicates that continued monitoring for zinc and aluminum is no longer warranted.

Request: Remove the action level requirements for zinc and aluminum from Outfall 020.

25. Issue: Update permit Attachments 1, 'Site Diagram' and 2, 'Monitoring Locations Schematic'.

Discussion: The site diagram and monitoring locations schematic, Attachments 1 and 2 to the permit, respectively, have become difficult to read due to repetitive copying. In addition, changes reflecting the proposed modifications in this application are incorporated.

Request: Replace the current Attachments 1 and 2, pages 10 and 11 of 17, with the updated versions enclosed in this permit modification application [Attachments 9&10].

26. Issue: Editorial changes.

Discussion: Several administrative/editorial changes to the permit are required due to changes in ownership of the facility, personnel changes, etc.

Request: Incorporate the following changes:

"* Page 12 of 17, Additional Requirements, Item Nos. 1.5 and 1.6 - change Niagara Mohawk to NMPNS

Dear Mr. Abbott:

The scheduled SPDES inspection of your facility was conducted on June 27, 2001. Although the Department did not perform surveillance sampling at any of the outfalls, the discharges from Outfalls 001,002, 020, and 030 appeared to be in compliance at the time of inspection. The remaining outfalls were not visible or had no discharge at the time of inspection.

Review of the Discharge Monitoring Reports (DMR's)'since the last scheduled inspectionindicates there was one exceedance of the SPDES permit's effluent limit for the parameter of Total Residual Oxidant (TRO) at Outfall 040 for the month of November;2000. No additional exceedances for this parameter at this outfall have occurred.

The tours of the facility on September 20, 2000 and June 27, 2001 have yielded several issues that will necessitate a request for a permit modification. These included the following:

I. The additional designation of the new chemical unloading station drain.

2. Clarification of permit language for Outfall 007.

3. A potential permit footnote for adjoining sumps at Outfall 040A.

4. The potential deletion of Outfall 022.

5. The reporting of a calculated value for copper at Outfall 040.

6. The discharge of the transformer containment to an identified outfall.

7. The potential deletion of Outfall 026.

I

8. The frequency of flow monitoring at Outfall 010.

9. The revision and/or clarification of footnote (a) iegarding the temperature differential conditions for reverse flow conditions and plant safety conditions during emergencies.

Please submit a request for a permit modification for these items and any others that may require identification in the SPDES permit.

The overall compliance rating of the facility is satisfactory.

If you have any questions or require additional information, please do not hesitate to contact me.

Thank you for your cooperation.

Sincerely,

.William F. McCarthy, P.E.

"The Intake temperature shall be considered that temperature existing after Intake water tempering. In addition, a during the winter season when Inlet Icing may occur, the delta temperature limitation may be exceeded by 35%

t for no more than one hour during each reverse flow or return to normal flow operation. These limitations may be N exceeded during periods when plant safety is at Issue or during periods when the circulating water system is experiencing an emergency situation that Is outside the normal operating envelope or routine maintenance, i.e.

L.* debris blocking the condensers, an emergency steam release, pump breakdown, etc. In the event of such an emergency/breakdown the permittee shall take corrective action as soon as possible. Where possible, situations

b. These limits and monitoring requirements shall not apply if this wastewater Is discharged upstream of the sewage treatment plant influent.

c. There shall be nio discharge of heat from the main condensers except heat may be discharged in blowdown from recirculated cooling water systems provided the temperature at which the blowdown is discharged does not exceed at any time the lowest temperature of recirculated cooling water prior to the addition of the makeup water.

Outfall 040 Includes cooling tower blowdown as well as service waterflow.

d. pH range of 4.0 - 9.0 is allowable for wastewater having a conductivity of less than 10 umho/cm.

e. Discharge from the two switchyard oil separators will be sampled before combination with waste stream 020.

f. Computer data, logged at least hourly, may be utilized for this parameter In order to verify compliance during normal operating conditions. During unusual operating conditions or In situations where the hourly data is near the outfall limitation, chart recorder data will be reviewed and utilized to demonstrate compliance.

g. Total copper samples should be obtained from the CWS blowdown line or the cooling tower basin. The total copper concentration for outfall 040 will be based on a calculated value taking into consideration the flow from the service water system.

h. Permit outfalls with this designation may Include wastewater sources of HVAC condensation, chlorinated city water,-fire protection water, circulating (lake) water, service (lake) water, groundwater, precipitation water,.

demineralized water and surface runoff water. These sources are approved for discharge from the permit listed outfalls.

IFs of /7 SPDES NO.: NY 000 1015 Part 1, Page 16 of 17 SPECIAL CONDITIONS - BEST MANAGEMENT PRACTICES

1. The permittee shall develop and implement a Best Management Practices (BMP) plan, within one year of EDP to prevent, or minimize the potential for, release of significant amounts of toxic or hazardous pollutants to the waters of the State through plant site runoff, spillage and leaks; sludge or waste disposal; or drainage from raw material storage If a plan exists, a letter indicating that all requirements addressed in this section must be submitted to this Department within one year of EDP.

2. The permittee shall review all facility components or systems (including material storage areas; in-plant transfer, process and material handling areas; loading and unloading operations; and sludge and waste disposal areas) where toxic or hazardous pollutants are used, manufactured, stored or handled to evaluate the potential for the release of significant amounts of such pollutants to the waters of the State. In performing such an evaluation, the permittee shall consider such factors as the probability of equipment failure or improper operation, settlement of facility air emissions, the effects of natural phenomena such as freezing temperatures and precipitation, fires, and the facility's history of spills and leaks. For hazardous pollutants, the list of reportable quantities as defined in 40 CFR, Part 117 may be used as a guide in determining significant amounts of releases. For toxic pollutants, the relative toxicity of the pollutant shall be considered in determining the significance of potential releases.

The review shall address all substances present at the facility that are listed as toxic pollutants under Section 307(a)(1) of the Clean Water Act or as hazardous pollutants under Section 311 of the Act or that are identified as Chemicals of Concern by the Industrial Chemical Survey.

3. Whenever the potential for a significant release of toxic or hazardous pollutants to State waters is determined to be present, the permittee shall identify Best Management Practices that have been established to minimize such potential releases. Where BMPs are inadequate or absent, appropriate BMPs shall be established. In selecting appropriate BMPs, the permittee shall consider typical industry practices such as spill reporting procedures, risk identification and assessment, employee training, inspections and records, preventive maintenance, good housekeeping, materials compatibility and security. In addition, the permittee may consider structural measures (such as secondary containment devices) where appropriate.

4. Development of the BMP plan shall include sampling of waste stream segments for the purpose of toxic "hot spot"'

identification. The economic achievability of technology-based end-of-pipe treatment will not be considered until plant site "hot spot" sources have been identified, contained, removed or minimized through the imposition of site specific BMPs or application of internal facility treatment technology.

5. The BMP plan shall be documented in narrative form and shall include any necessary plot plans, drawings or maps.

Other documents already prepared for the facility such as a Safety Manual or a Spill Prevention, Control and Countermeasure (SPCC) plan may be used as part of the plan and may be incorporated by reference. A copy of the BMP plan shall be maintained at the facility and shall be available to authorized Department representatives upon request As a minimum, the plan shall include the following BMP's:

a. BMP Committee f. Preventive Maintenance

b. Reporting of BMP Incidents g Good Housekeeping c Risk Identification and Assessment h Materials Compatibility

d. Employee Training i. Security

e. Inspections and Records

6. The BMP plan shall be modified whenever changes at the faciiity materially increase the potential for significant releases of toxic or hazardous pollutants or where actual releases indicate the plan is inadequate A "hot spot" is a segment of an industrial facility; including but not limited to soil, equipment, material storage areas, sewer lines etc ; which contributes elevated levels of problem pollutants to the wastewater and/or storm water collection system of that facility. For the purposes of this definition, problem pollutants are substances for which end of pipe treatment to meet a water quality or technology requirement may, considering the results of wastestream segment sampling, be deemed unreasonable. For the purposes of this definition, an elevated level is a concentration or mass loading of the pollutant in question which is adequately higher than the end of pipe concentration of that same pollutant so as to allow for an economically justify removal and/or isolation of the segment and/or B.A.T. treatment of wastewaters emanating from the segment.

a. The intake temperature for this designated outfall shall be considered that temperature existing after intake waters have been tempered. The Intake Discharge Temperature Difference limit may be exceeded during periods when plant safety is at issue, during periods when the circulating water system (CWS) is experiencing an emergency situation that is outside the normal operating envelope or during routine maintenance of the system, such as, but not limited to, the following situations: debris blockage of a CWS component, an emergency steam release, pump breakdown, etc. In the event of such an emergency/breakdown, the permittee shall take corrective action to bring the temperature parameter within the permit limit as soon as possible. The permittee, whenever possible, should take action to avoid temperature parameter exceedence from June through September.

In the event that the facility is experiencing inlet icing conditions during the winter season, the Intake-Discharge Temperature Difference limit may be exceeded by 35%, or 12.25°F, for no more than one hour during each reverse flow or return to normal flow operation. The facility may exceed the 35% criteria for a period of fifteen (15) minutes when the facility returns to normal flow configuration. This momentary increase during return to normal flow configuration is acceptable.

The permittee shall indicate in the Discharge Monitoring Report the reason for operating outside of the permit limit, and the dates and times of the associated event. In no case shall the permit limitation be exceeded for more than 5% of the operating time during the operating year.

g. Total copper samples should be obtained from the CWS blowdown line or the cooling tower basin. The total copper concentration for Outfall 040 will be based on a calculated value taking into consideration the flow from the service water system. The equation and parameters for performing this calculation are as follows:

Total copper concentration at Outfall 040 =

[CWS]cu x CWS Blowdown Flow [CWS]cU x Tempering Flow

ATTACHMENT 1

Form WTCFX (9/99)

NYSDEC - Division of Water Water Treatment Chemical (WTC) Usage Notification Requirements for SPDES Permittees InstructionsPage purpose New or increased use of a WTC requires prior DEC review and authorization. At a minimum, the permittee must notify the DEC in writing of its intent to change WTC use. The DEC will review that submittal and determine if a formal SPDES permit modification is necessary or whether WTC review and authorization may proceed outside of the formal permit administrative process. The majority of WTC authorizations do not require formal SPDES permit modification. Notification requirements are summarized below to ensure the submission of complete information.

WTCs which are used in closed systems and cannot be discharged or those which are discharged to municipal STP do not require DEC review. Examples of WTCs include, biocides, coagulants, conditioners, corrosion inhibitors, defoamers, flocculants, scale inhibitors, sequestrants, and settling aids. DEC staff may also direct you to use this form for review and authorization of substances other than WTCs, e.g. process chemicals.

Notification Requirements/Instructions.

For each new or increased use of a WTC please complete items la, and 2 - 13 on the attached 3 page form, entitled Water Treatment Chemical Usage Notification Requirements for SPDES Permittees, attach a copy of the product label and Fax or Mail the information to:'

Permit writer: Paul Kolakowski ITelephone: (518) 40 2-SlO Fax: (315) 402-9029 Address: 625 Broadway, Albany, NY 12233-3506 Alternatively, the permittee may, at a minimum, complete items la, 2 - 8 and 13 then forward the form to the WTC manufacturer who must then complete the remaining items (9 - 12) and items lb and 14. The manufacturer must then send the completed form directly to the permit writer. This alternative method may be necessary because the WTC nanufacturer may be reluctant to reveal trade secret product formulations to the permittee.'

For completion of item 12 (Toxicity Info) please assure that the tests were conducted in accordance with the EPA Toxicity Manual and that the results are for the appropriate receiving water (i.e. fresh water or salt water)? In general, submissions which do not include any toxicity information will not be authorized. Submissions containing incomplete toxicity information will be reviewed using conservative safety factors which may prevent authorization or result in the permit being modified to include routine effluent toxicity testing.

The permittee must demonstrate that the use and discharge of any WTCs containing phosphorus, tributary to the Great Lakes Basin or other ponded waters, is necessary and that no acceptable alternatives exist. Please note that in some cases your permit may require modification to regulate phosphorus.

After reviewing the submittal the permit writer will complete items 15 and 16 and fax or mail a copy of the completed form to the person identified in item 2.c.

Common Reasons Which Prevent Letter Authorization of a WTC

"* Submission of incomplete or inaccurate information.

"* High WTC toxicity compared to available receiving stream dilution or predicted exceedance of AWQC.

"* Department review indicates that a SPDES permit modification is necessary.

B. The discharge shall not cause or contribute to a violation of water quality or an exceedance of AWQC.

C. The permittee must maintain a logbook of all WTC use, noting for each WTC the date, time, exact location, and amount of each dosage, and, the name of the individual applying or measuring the chemical. The logbook must also document that adequate process controls are in place to ensure that excessive levels of WTCs are not used and subsequently discharged through outfalls. The permittee shall retain the logbook data for a period of at least 3 years. This period may be extended by request of the DEC.

D. The permittee shall provide an annual report, attached to the December DMR, containing the following information for each outfall: the current list of WTCs authorized for use and discharge by the DEC, for each WTC the amount in pounds used ,duringthe year, identification of authorized WTCs the permittee no longer uses, and any other pertinent information.

NYSDEC - Division of Water

-* Water Treatment Chemical (WTC) Usage Notification Requirements for SPDES Permittees InstructionsPage Purpose New or increased use of a WTC requires prior DEC review and authorization. At a minimum, the permittee must notify the DEC in writing of its intent to change WTC use. The DEC will review that submittal and determine if a formal SPDES permit modification is necessary or whether WTC review and authorization may proceed outside of the formal permit administrative process. The majority of WTC authorizations do not require formal SPDES permit modification. Notification requirements are summarized below to ensure the submission of complete information.

WTCs which are used in closed systems and cannot be discharged or those which are discharged to municipal STP do not require DEC review. Examples of WTCs include, biocides, coagulants, conditioners, corrosion inhibitors, defoamers, flocculants, scale inhibitors, sequestrants, and settling aids. DEC staffmay also direct you to use this form for review and authorization of substances other than WTCs, e.g. process chemicals.

Notification Requirements/Instructions For each new or increased use otfa WTC please complete items la, and 2 - 13 on the attached 3 page form, entitled Water Treatment Chemical Usage Notification Requirements for SPDES Permittees, attach a copy of the product label and Fax or Mail the information to:

wermitwiter: Paul Kolakowski j Telephone: (518) 402-81041Fax: (518) 402-9029 Address: 625 Broadway, Albany, NY 12233-3506 Alternatively, the permittee may, at a minimum, complete items la, 2 - 8 and 13 then forward the form to the WTC manufacturer who must then complete the remaining items (9 - 12) and items lb and 14. The manufacturer must then send the completed form directly to the permit writer. This alternative method may be necessary because the WTC nanufacturer may be reluctant to reveal trade secret product formulations to the permittee.1 For completion of item 12 (Toxicity Info) please assure that the tests were conducted in accordance with the EPA Toxicity Manual and that the results are for the appropriate receiving water (i.e. fresh water or salt water)? In general, submissions which do not include any toxicity information will not be authorized. Submissions containing incomplete toxicity information will be reviewed using conservative safety factors which may prevent authorization or result in the permit being modified to include routine effluent toxicity testing.

The permittee must demonstrate that the use and discharge of any WTCs containing phosphorus, tributary to the Great Lakes Basin or other ponded waters, is necessary and that no acceptable alternatives exist. Please note that in some cases your permit may require modification to regulate phosphorus.

After reviewing the submittal the permit writer will complete items 15 and 16 and fax or mail a copy of the completed form to the person identified in item 2.c.

Common Reasons Which Prevent Letter Authorization of a WTC

• Submission of incomplete or inaccurate information.

• High WTC toxicity compared to available receiving stream dilution or predicted exceedance of AWQC.

• Department review indicates that a SPDES permit modification is necessary.

Footnotes:

(1) If requested, the Department will restrict access to trade secret information to the extent authorized by law.

,2) Submission of both acute (48 or 96 hour0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> LCS0 or EC50) and chronic (NOEC) test results for at least one vertebrate and one invertebrate species are required. Refer to the following three manuals: EPAI600/4-90/027F (1993); EPA/600/4-91/002(1994);

EPAI600/4-91/003 (1994); or their replacements.
