1.1 BACKGROUND

On behalf of Yankee Atomic Electric Company (Yankee), Environmental Resources Management (ERM) has prepared this March 2004 Groundwater Field Sampling Plan (FSP) for the Yankee Nuclear Power Station (YNPS)located at 49 Yankee Road in Rowe, Massachusetts (Figure 1). The FSP has been prepared as a supplement to the Draft Quality Assurance Project Plan, Site Closure, Yankee Nuclear Power Station, Rowe, Massachusetts and the Final Groundwater Sampling Plan, Yankee Nuclear Power Station, July 2003. The FSP outlines the approach and methods for characterizing groundwater quality at the site as part of the overall site closure program. This FSP addresses only non-radiological groundwater characterization activities.

1.2 PURPOSE& SCOPE The purpose of the March 2004 Groundwater FSP is to:.establish the procedures and rationale for groundwater sampling activities in support of site closure;* ensure that groundwater sampling data are consistent with applicable procedures;

.ensure that the Data Quality Objectives (DQOs) for site closure are met;.provide data to support preparation of the License Termination Plan (as required by the Nuclear Regulatory Commission);

and.support the site characterization and closure activities.

The data generated under the FSP will be validated and input into the site database.

The results from the baseline sampling round as well as subsequent sampling rounds will be used in conjunction with Data Usability reports that are being prepared regarding the historic data to determine the need for, and scope of, future groundwater sampling events. The data will also be used to support human health and ecological risk assessments that will be prepared as part of the site closure program.The scope of the March 2004 Groundwater FSP includes sampling of wells listed in Table 2. See Table I for a summary of groundwater well information and location descriptions.

• Surface Water and Sediment Sample Collection All applicable SOPs can be found in the Final Groundwater Sampling Plan, Yankee Nuclear Power Station, July 2003.2.2 SAMPLE LOCATIONS AND DESIGNATIONS A list of locations to be sampled for groundwater is provided in Table 2.The groundwater sample locations are shown on Figure 2.The groundwater samples will be identified using a unique sample identification.

The sample designations willuse the naming convention as detailed in the YNPS QAPP. The sample designations for the groundwater sampling program are detailed in Table 2.2.3 SAMPLING PROCEDURES

2.3.1 Monitoring

Well Sampling All of the monitoring wells will be gauged prior to sampling in accordance with DP-9745 Groundwater Level Measurement and Sam pler ERNI 2 YANKEE 00 i5i81 REVISED 3/15/'04 Collection in Observation Wells. Water level measurements wvill be made using an electronic water level probe marked in 0.01-foot intervals.

After gauging, the monitoring wells will be sampled from the midpoint of the well screen using low-flow sampling techniques, as outlined in DP-9745 Groundwater Level Measurement and Sampler Collection in Observation Wells. Geochemical field parameters will be measured for wells sampled by low-flow sampling techniques at the time of sample collection, including:

temperature, conductivity, pH, dissolved oxygen, turbidity, and oxidation-reduction potential.

The field meters used during groundwater sampling will include a water quality instrument for collection of field parameters and a electric water level meter. In accordance with the QAPP, all equipment will be calibrated and operated in accordance with the manufacturer's recommended procedures.

Dedicated sampling equipment will be used where feasible.

At wells where the depth to water is greater than 30 feet, a low-flow submersible or bladder pump will need to be used. All reused sampling equipment will be decontaminated prior to, and following, sample collection in accordance with the QAPP.2.4 ANALYTICAL PROGRAM 2.4.1 Non'-radiological Parameters The groundwater analytical program is summarized in Table 2. The bottle requirements are detailed in Table 3. The groundwater investigation will include the analysis of one or more of the following non-radiological parameters: " Volatile Organic Compounds (VOCs) by GC/MS, SW-846 Method 8260B VOCs;.* Semi-Volatile Organic Compounds (SVOCs) by GC/MS, SW-846 Method 8270C SVOCs;" Polychlorinated Biphenyls (PCBs) dissolved and total by GC, SW-846 Method 8082PCBs;* Chlorinated Herbicides by GC, SW-846 Method 81511;" Diesel Range Organics (DRO) by GC, SW-846 Method 801513;* Lead dissolved and total by SW-846 6010B1;* Silver dissolved and total by SW-846 601.013;ER.\I 3 YANKEE 00 15181 REVISED 3/15/01 ERM\3 YANKEE 00 151S1 REVISED 3/15/01

1.3 Metals

(PP13) Metals by SW-846 6010B Each well will require a different suite of the above analyses as described in Table 2. Alpha Analytical Laboratories located in Westborough, MA will perform the EPH/VPH analysis when feasible based on radiological screening.

Northeast Laboratory Services, located in Waterville, Maine, will conduct all other non-radiological analyses.Samples requiring filtration include PCBs, lead, and silver. These samples will be collected into containers as described in Table 3 and sent to the laboratory within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, or as soon as possible.

Sampling personnel will indicate on the COC which samples require filtration.

2.4.2 Radiological

Parameters Groundwater samples will also be collected for radiological site characterization activities.

The radiological samples will be collected following the collection of non-radiological samples. Radiological sampling is not covered in this FSP. Framatome ANP Environmental Laboratory in Westborough, Massachusetts will conduct the radiological analyses.2.5 SAMPLE SECURITY AND CUSTODY Groundwater samples will be submitted to the laboratory under proper chain-of-custody procedures.

Non-radiological samples will be preserved on ice or in a refrigerator.

Sample handling will be documented using chain-of-custody protocols in accordance with DP-8123, Saraple Security and Chain of Custody.2.6 MANAGEMENT OF INVESTIGATION DERIVED WASTES All purge water generated during well sampling activities will be containerized on-site. The fluids will be screened for radiological constituents.

Following screening YNPS personnel will dispose of the wastes in accordance with the applicable YNPS procedures.

3.0 QUALTIY

ASSURANCE AND QUALTIY CONTROL 3.1 QUALITY ASSURANCE PROJECT PLAN A QAPP has been prepared to provide a standard method of assuring that data collected during site characterization activities is of sufficient quality to support future decisions regarding decommissioning activities and or remedial actions at the site. The primary purpose of the QAPP is to describe the means by which data collected in the field will be validated against predetermined standards, ensuring that data meets minimum quality standards prior to being used for decision-making purposes.

The flow of data is important to data quality, as it ensures that appropriate project personnel have adequate opportunities to review data with importance to future site decisions.

As such, the QAPP specifies the methods and means for ensuring the data generated during site characterization activities serves the purpose of site closure and property transfer.The following provides a list of the sections of the QAPP that are most relevant to the field sampling activities:

QAPP Section Topic 9_1 Field Investigation and DocuImentation Procedures

9.2 Preparation

9.3 Decontamination

9.4 Field Equipment Usage and Maintenance 10.A Sample Tracking System 10.2 Sample Custody 13.1 Field Quality Control 3.2 CLEANING AND DECONTAMINATION OF EQUIPMENT To the degree possible, dedicated and/or disposable sampling equipment will be used for sampling.

Non-dedicated sampling equipment used to collect samples will be cleaned and decontaminated prior to its initial use, between each sampling location and after the final use. The following 2 ERi11I 6 YANKEE 0)0 I5181 REVISL- /1/-

general procedures will be adhered to concerning decontamination efforts: 1. If visual signs such as discoloration indicate that decontamination was insufficient, the equipment will again be decontaminated.

If the situation persists, the equipment will be taken out of service until the situation can be corrected.

2. Verification of the non-dedicated sampling equipment cleaning procedures will be documented by the collection of field equipment rinsate blanks, at a frequency in accordance with the QAPP.3. All properly decontaminated equipment will be stored in aluminum foil or plastic bags during storage and transport.

Decontamination protocols will be strictly adhered to in order to minimize the potential for cross-contamination between sampling locations and contamination of off-site areas. Liquids generated during the decontamination process will be collected, containerized and appropriately labeled for disposal.

Waste liquids will be stored on site until determination of potential hazard class and final disposition.

Only pre-cleaned laboratory-certified sample containers will be used. The laboratory will also provide sample coolers, ice packs, trip blanks, and temperature blanks.More specific decontamination procedures are outlined in the QAPP and SOPs.3.3 QUALITY ASSURANCE/QUALITY CONTROL SAMPLES The following Quality Assurance

/ Quality Control samples will be collected during the groundwater sampling for nonradiological samples: " Trip blanks -One trip blank per each set of up to 20 sample containers to be analyzed for VOC and TPH-GRO. There must be at least one trip blank in every cooler used to ship samples to the laboratory for VOC and TPFI-GRO analysis." Temperature blanks -One temperature blank per cooler. The temperature of the trip blank will be measured upon receipt of the cooler at the laboratory.

• Equipment rinsate blank -The majority of groundwater samples will be collected using dedicated sampling equipment.

However, where ERIM 7 YANKEE 00 15i8l REVISED 3/ 15/04 the depth to water is greater than 30 feet, a submersible pump will be used. A rinsate sample will be collected from the pump at a rate of one sample per 20 sampling lqcations.

The rinsate blanks will be analyzed for the same parameters as the samples that were collected using the equipment.

Field duplicates

-Field duplicates will be collected at the rate of one duplicate per 20 samples. Samples locations where duplicates will be collected are listed in Table 2. Field duplicates will be submitted for the same analyses as the actual sample.Matrix spikes -Matrix spikes will be collected at the rate of one matrix spike and one matrix spike duplicate per 20 samples. Samples locations where matrix spikes will be collected are listed in Table 2.Matrix spikes/matrix spikes duplicates will be analyzed for the same analyses as the actual sample.8 YA~KEL JO 15181 REVISED 3/15184 8 YANKEE 00 15181 REVISED ý/ 15t04

1.1 BACKGROUND

On behalf of Yankee Atomic Electric Company (Yankee), Environmental Resources Management (ERM) has prepared this Sediment Field Sampling Plan (FSP) for the Yankee Nuclear Power Station (YNPS) located at 49 Yankee Road in Rowe, Massachusetts (Figure 1). The FSP has been prepared as a supplement to the Draft Quality Assurance Project Plan, Site Closure, Yankee Nuclear Power Station, Rowe, Massachusetts.

The FSP outlines the approach and methods for characterizing sediment quality at the site as part of the overall site closure program. Other media-specific FSPs will be prepared as the site closure activities proceed. This FSP addresses non-radiological sediment characterization activities.

Radiological characterization of sediments is not planned at this time.1.2 PURPOSE & SCOPE The purpose of the Sediment FSP is to:* establish the procedures and rationale for sediment sampling activities in support of site closure;" ensure that sediment sampling data are consistent with applicable procedures;

• ensure that the Data Quality Objectives (DQOs) for site closure are met; and* support the site characterization and closure activities.

Sediment sampling for polychlorinated biphenyls (PCBs) has been performed as part of the assessment of a release of PCB-containing paint chips. Two areas of sediment are currently targeted for remediation based on the assessment activities (see Figure 1). The data generated under the FSP will be used to assess the potential for impact to sediment by oil or hazardous materials beyond the proposed remedial areas where there are no current plans for remediation.

The data generated under the FSP will be validated and input into the site database.

The results from the sampling round will be used in conjunction with Data Usability reports that are being prepared regarding the historic data to determine the need for, and scope of, future sediment E R-%I YANKEE 2107 S/I/03 sampling events. The data will also be used to support human health and ecological risk assessments that will be prepared as part of the site closure program.The scope of the Sediment FSP includes sampling of sediments in Sherman Reservoir, Wheeler Brook, West Storm Drain, and the Deerfield River (see Table 1 for a summary of sediment sampling locations).

2.0 SEDIMENT

SAMPLING PROGRAM 2.1 STANDARD OPERATING PROCEDURES YNPS Standard Operating Procedures (SOPs) applicable to the sediment investigation include: " DP-8124 Collection of Pond Sediment Samples for Site Characterization" DP-8123 Sample Security and Chain of Custody* DP-8120 Collection of Site Characterization and Site Release Samples Appendix A contains the YNPS SOPs applicable to this FSP.2.2 SAMPLE LOCATIONS AND DESIGNATIONS A list of locations to be sampled for sediment is provided in Table 1. The sediment sample locations are shown in Figure 1 and background locations are shown in Figure 2.The sampling program was developed based on the location of the YNPS National Pollution Elimination System (NPDES) outfall locations and site topography.

As shown in Figure 1, YNPS has three NPDES outfall locations:

Outfall Processes Receiving Body 003/005 Stormwater from eastern portion of YNPS Sherman Reservoir 001/010 Discharge from circulating water system and Sherman Reservoir service water system 002/004 Stormwater from western portion of YNPS West Storm Drain As noted in Section 1.2, areas that are currently targeted for sediment remnediation due to the release of PCB-containing paint chips are shown in Figure 1. Since it is expected that those areas will be excavated, they were excluded from the sediment characterization program.Within Sherman Reservoir, sediment cores will be collected to a depth of 18 inches. The sediment samples will be collected at five intervals from E RA 3 E3YANKEE 2107 8/8/03 the shoreline:

25 feet, 50 feet, 100 feet, 200 feet, and 500 feet. A sample will be submitted for analysis from the 0 to 4 inch interval from each location.

A sample will also be collected for analysis at a depth of 12 to 18 inches along the 50-foot transect.

The remaining core samples will be stored in a freezer at YNPS, pending the results of the initial round of analyses.Six background samples will be collected from the northern end of Sherman Reservoir in depositional areas. A sample will be submitted for analysis from the 0 to 4 inch interval from each location.

Approximate sample locations are shown on Figure 2, but may be adjusted based on field observations.

Within Wheeler Brook, six surficial sediment samples will be collected to assess sediment quality upstream and downstream of the Southeast Construction Fill Area. Within the West Storm Drain, five surficial samples will be collected approximately every 100 feet. Within the Deerfield River, six surficial samples will be collected from depositional areas. The Deerfield River samples will be collected both upstream and downstream of the discharge point of the West Storm Drain. Surface sediment samples will be collected for analysis from 0 to 4 inches in Wheeler Brook, the West Storm Drain, and the Deerfield River.The sediment samples will be identified using unique sample identification.

The sample designations will use the naming convention as detailed in the YNPS QAPP. The sample designations for the sediment sampling program are detailed in Table 1.2.3 SAMPLING PROCEDURES 2.3.1 Boat Sampling Sediment samples in Sherman Reservoir will be collected under ERM's oversight by TG&B Marine Services of Falmouth, MA_ Samples will be collected in compliance with YNPS Procedure DP-8124 Collection of Pond Sediment Samples for Site Characterization.

A boat-mounted Vibracore System will be used to direct push or vibrate the core sampler into the sediment.

The core sampler consists of a two-foot stainless steel casing with a removable two-inch diameter polycarbonate sleeve. A plug is placed at the top of the polycarbonate sleeve to prevent sediment from extending above the sleeve height. After coring, the sleeve is removed from the casing, capped, labeled, and brought to shore for sampling.

On shore, the portion of the core to be sampled will be extracted and the remaining core will be capped, placed in a sealed plastic bag, and stored ERM 4 YANKEE 2107 S/1/03 in a freezer at YNPS. The portion of the core to be submitted for laboratory analysis will be cut open to visually inspect and classify the sediment stratigraphy.

Visual observations will be logged on sediment sampling forms.Dedicated sampling equipment will be used where feasible.

Reused sampling equipment will be decontaminated prior to, and following, sample collection in accordance with the YNPS QAPP.2.3.2 Manual Sampling Sediment samples will be collected manually from the Wheeler Brook, the West Storm Drain, and the Deerfield River. Samples will be collected in compliance with YNPS Procedure DP-8120 Collection of Site Characterization and Site Release Samnples.

A stainless steel trowel and/or hand auger will be used to obtain each sediment sample from a depth of 0 to 4 inches. Sampling will be performed at downstream locations first, working upstream to reduce the potential for suspended sediments to impact the sample results. Field observations, including sampling location descriptions, will be recorded in a field logbook.2.4 ANALYTICAL PROGRAM 2.4.1 Non-radiological Parameters The sediment analytical program is summarized in Table '. The analytical parameters were selected based on the types of chemicals used at the plant as outlined in the QAPP. In the vicinity of Outfall 001/010, the list of compounds was expanded to include chemicals associated with the operation of the cooling water system (e.g., boron, lithium, and hydrazine).

The sediment investigation will include the analysis of sediment samples for the following non-radiological parameters:

• Volatile Organic Compounds (VOCs) by GC/MS, SW-846 Method 8260B (both low-level, deionized water-preserved, and medium-level, methanol preserved, sediment samples will be collected at each sample location in accordance with SW846 Method 5035 VOC sampling procedures;

• Semi-Volatile Organic Compounds (SVOCs) by GC/NMS, SW-846 Method 8270C;* Polychlorinated Biphenyls (PCBs) by GC, SW-846 Method 8082;E5 R YANKEr-7 2107 S/8/03

" Diesel Range Organics (DRO) by GC, SW-846 Method 8015B* Gasoline Range Organics (GRO) by GC, SW-846 Method 8015B" Priority Pollutant 13 Metals (PP13) Metals by SW-846 6010B and 7000 Series (for antimony, arsenic, lead, selenium, and thallium).

Chromium species will be identified for detections;

• Boron and Lithium by SW-846 6010B;* Hydrazine by Ion Chromatography (1C); and* Total Organic Carbon Northeast Laboratory Services, located in Waterville, Maine, will conduct the majority of the non-radiological analyses.

Severn Trent Laboratory (STL)-Denver will perform the hydrazine analyses, and STL-Connecticut will perform TOC analyses.2.4.2 Radiological Parameters Yankee personnel will screen sediment samples on-site in accordance with YNPS screening procedures.

Laboratory analysis for radiological constituents will not be performed on the sediment samples.2.5 SAMPLE SECURITY AND CUSTODY Sediment samples will be submitted to the laboratory under proper chain-of-custody procedures.

Samples will be preserved on ice or in a refrigerator and sample handling will be documented using chain-of-custody protocols in accordance with DP-8123, Sample Security and Chain of Custody.2.6 MANAGEMENT OF INVESTIGATION DERIVED WASTES Sediment sampling waste will be containerized on-site. The wastes will be screened for radiological constituents.

Following screening YNPS personnel will dispose of the wastes in accordance with the applicable YNPS procedures.

2.7 SCHEDULE

The sediment-sampling program is scheduled to begin on 12 August 2003.The completion schedule for the sampling activities is dependent on field 6 YANKEE 2107 8/8/03 conditions, but is scheduled to be completed within two weeks of commencement.

9.4 Field Equipment Usage and Maihntenance 10.1 Sample Tracking System 102 Sample Custody 13.1 Field Quality Control 3.2 CLEANING AND DECONTAMINATION OF EQUIPMENT To the degree possible, dedicated and/or disposable sampling equipment will be used for sampling.

Non-dedicated sampling equipment used to collect samples will be cleaned and decontaminated prior to its initial use, between each sampling location and after the final use. The following ERMv 8 YANKEE 2107 8/8/03 general procedures will be adhered to concerning decontamination efforts: 1. If visual signs such as discoloration indicate that decontamination was insufficient, the equipment will again be decontaminated.

If the situation persists, the equipment will be taken out of service until the situation can be corrected.

2. Verification of the non-dedicated sampling equipment cleaning procedures will be documented by the collection of field equipment rinsate blanks, at a frequency in accordance with the QAPP.3. Properly decontaminated equipment will be stored in aluminum foil or plastic bags during storage and transport.

Decontamination protocols will be strictly adhered to in order to minimize the potential for cross-contamination between sampling locations and contamination of off-site areas. Liquids generated during the decontamination process will be collected, containerized and appropriately labeled for disposal.

Waste liquids will be stored on site until determination of potential hazard class and final disposition.

Only pre-cleaned laboratory-certified sample containers will be used. The laboratories will also provide sample coolers, ice packs, trip blanks, and temperature blanks.More specific decontamination procedures are outlined in the QAPP and SOPs.3.3 QUALITY ASSURANCE

/ QUALITY CONTROL SAMPLES The following Quality Assurance

/ Quality Control samples will be collected during the sediment sampling:* Trip blanks -At least one trip blank per cooler containing VOC or GRO samples (a minimum of one'trip blank per 20 samples).

Separate trip blanks will be prepared and analyzed for low-level (deionized water-preserved) 8260B VOCs, medium-level (methanol preserved) 8260B VOCs, and GRO.* Temperature blanks -One temperature blank per cooler. The temperature of the trip blank will be measured upon receipt of the cooler at the laboratory.

• Equipment rinsate blank -The majority of sediment samples will be collected using dedicated sampling equipment.

However, manual sampling will be conducted using a stainless steel trowel. A rinsate sample will be collected from the stainless steel trowel at a rate of one sample per 20 sampling locations.

The rinsate blanks will be analyzed for the same parameters as the samples that were collected using the equipment.

Due to the short (48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />) holding time for aqueous hydrazine analysis, samples will be sent directly to STL-Denver via overnight carrier so that the samples may be extracted as soon as possible following sampling.* Field duplicates

-Field duplicates will be collected at the rate of one duplicate per 20 samples. Samples locations where duplicates will be collected are listed in Table 1. Field duplicates will be submitted for the same analyses as the actual sample.* Matrix spikes -Matrix spikes will be collected at the rate of one matrix spike per 20 samples. Samples locations where matrix spikes will be collected are listed in Table 1. Matrix spike/matrix spike duplicates (MS/MSDs) will be collected for organic parameters.

Matrix spike/matrix duplicates (MS/MD) will be collected for inorganic and wet chemistry analyses.ERM\10 YANKEE 2107 5/8/03 4-0 PROJECT DOCUMENTATION Data management tasks pertinent to project documentation and records, laboratory deliverables, data reporting formats, data handling and management, and data review assessment are presented in the QAPP.The following field sample collection records will be completed at the time of sample collection:

• Field logbook" Sediment sampling field logs* Chain of custody forms* Shipping records (airbills), if any* Telephone logs, as appropriate The project documentation will be provided to the Yankee Environmental Oversight Supervisor at the completion of each sampling event. In addition, any deviations from the FSP will be documented in a memorandum to the Yankee Environmental Oversight Supervisor.

DP-9725, "Potable Water Quality Monitoring" 6- DP-9745, "Ground Water Level Measurement and Sample Collection in Observation Wells" 7. DP-8813, "Sample Receipt and Preparation" DISCUSSION To ensure the integrity of a sample and the defensibility of its analytical results, its chain of custody should be documented.

For samples analyzed off-site, this is done with the chain of custody form.For samples analyzed at the YNPS site, this is done by logging samples in and out of each on-site facility (see DP-8813) .Where a sample is tracked first on one system (e.g., the Sample Log), then on another (e.g., chain of custody form), the sample's custody should be traceable, without any gaps, across both systems.Also important is to ensure the integrity of the sample's security.Proper security will prevent or minimize sample loss, tampering and inadvertent mishandling.

PROCEDURE A. Initiation of Chain of Custody Form I. A Chain of Custody Form (DPF-8123.1) shall be initiated by the sample collector for all site characterization and other site samples that are analyzed offsite. Multiple samples may be included on a single form.2. The sample collector shall initiate the Chain of Custody Form (DPF-8123.1) at the time of collection.

Radiological samples that have been tracked in accordance with DP-8813[71 may have their Chain of Custody Form initiated just prior to shipment off-site. DP-8123 Rev. 9 3- The sample collector shall fill out DPF-8123.1, and sign and date the form, using the guidance found in Appendix A.Ensure that the information entered on the sample container is the same as that entered on DPF-8123-I_

4. Note the chain of custody form number (found at the top of DPF-8123.1,)

in the Field Log Book (if one is used).5. Once a Chain of Custody Form has been initiated, the original copy of the form shall stay with the sample(s), at least until such time as described in Step B.3.6. When an additional chain of custody form is to be initiated for a sample that is already on a chain of custody form (e.g., the sample has been split and each aliquot is to be sent to a different analytical laboratory), a notation shall be made in the "Comment" column on each form cross-referencing the two form numbers.B. Transfer of Sample Custody NOTE: Relinquishing custody of a sample is not required when the sample is transferred among members within any laboratory or count room, or between Chemistry, HP, or Environmental sample collectors and the site countroom or laboratory analysis.1. When the sample collector turns the sample over to another individual (e.g., the Safety Oversight Department staff or the YNPS Sample Prep Trailer), that individual shall sign the first "Received by" block, including the date and time of receipt.2. Each time the sample(s) changes custody, the relinquishing party and the receiving party shall sign and date the form within the next available location.3. The analytical laboratory shall be instructed to return the white page of the completed Chain of Custody Form (DPF-8123.1) to the contact name on the form along with the analytical results.4- The completed DPF-8123.1 shall be reviewed and filed by the contact person or his/her designee as part of the data package.C. Use of Commercial Couriers 1. Just prior to turnover to a commercial courier, relinquish the samples by date and time of shipment and signature on DPF-8123.1.

2. Note in the "Sample Shipped Via" location on DPF-8123.1 the courier utilized if applicable and the Bill of Lading number which is printed at the top of each air bill in bold black numbers.NOTE: A "Received By" signature is not required until receipt by the analytical lab.3. Remove and retain the rear-most carbon copy of DPF-8123.1.

4. Seal the original DPF-8123.1 in the container along with the samples.5. When the original signed DPF-8123.1 returns from the analytical lab, attach the air bill and file with sample results.

VV- b I 2I Rev. 9 The completed DPF-8123.i, with air bill and rear most carbon copy shall be reviewed and filed by the contact person or his/her designee as part of the data package.D_ On-Site Sample Security i. Following sample collection, the sample collector shall do one of the following, in accordance with the transfer of custody requirements in this procedure:

Deliver the sample(s) to an on-site facility (e.g., sample preparation lab or count room);Deliver the sample(s) to an off-site lab (either directly or by turning over to a courier);Store the sample(s) in a secure manner (see below)until the sample(s) is delivered to the on-site sample preparation facility or count room, or until the sample(s) is sent to an off-site laboratory.

2. At any time following field collection, samples must be stored in a secure manner, which shall include one or more of the following:

Direct physical control or under direct visual observation by an individual; Storage in a locked container, locked cabinet (e.g., refrigerator) ,or individual locked transport box (e.g.for concrete cores).Storage in a locked room or building having limited access (e.g., the YNPS Sample Prep Trailer);* .Tamper evident seal on the sample container.

A single tamper evident seal may be used on a single container (e.g., cooler) containing multiple samples.NOTE: Smear samples shall be considered secure when loaded on a planchet rack in the Radiation Protection count room. (Tamper evident seals shall not be applied to planchet racks.) All samples shall be considered secure while on a detector in the Radiation Protection or Chemistry count room.FINAL CONDITIONS

1. Original chain of custody forms (DPF-8123.1) have been completed and filed for all samples as identified in this procedure's"Scope". Ensure completed DPF-8123.1 is transferred to the applicable data package. Commercial courier receipts or bills of lading, if applicable, are also filed.2. Samples that are on-site are stored in a secure manner.

AP-0221, "Plant Record Management" DISCUSSION Environmental samples are collected from surface soils, subsurface soils, sediments, asphalt, and liquids to identify a media's contamination status for site characterization and site release purposes.

Soil, asphalt and concrete stock piles will be sampled to determine their final disposition (e.g., soil for back fill or release, asphalt and concrete for free release)..

The type of sample to be collected (e.g., grab, composite, etc.) and the suite of contaminants for which it will be analyzed should be identified in the field sampling plan. All samples will be prepared for analysis in accordance with DP- DP-8120 Rev. 7 accordance with AP-0052 [10) This procedure addresses the steps to collect each type of sample.Quality control measures will be an integral part of all activities related to obtaining and testing of samples. These measures are intended to help assure the accuracy of all data. They include: Implementation of all work based on written procedures Direction and documentation of all activities by a cognizant engineer* Performance of key activities by individuals qualified to carry out such activities , Precautions to prevent cross-contamination of samples Verification of analysis results by an independent laboratory Use of analytical laboratories with QA/QC programs Chain-of-custody documentation of samples PRECAUTIONS

1. All samples collected from within the Radiological Control Area (RCA) will be initially handled as if contaminated.

A GM frisker will be used to periodically screen equipment and newly-collected samples for gross contamination,,-

If radioactivity is detected above background.

Label the sample as "Caution Radioactive Material" in accordance with OP-8100 18) and take the necessary precautions to prevent the contamination of other samples, equipment or personnel., 2- Latex," nitrile or equivalent glbves shall be worn when handling sampli material collected from on site, and when cleaning tools that were used in the collection of those samples. Clean gloves shall :be used at each new sampl-ng site.3. When collecting samples in the RCA, hands and feet should be periodically monitored for contamination with a GM frisker.4. For safety purposes, holes in concrete floors, soil or asphalt shall :be patched or filled as soon as practicable.

5. For major excavations a Job Hazards Checklist will be completed and reviewed with the Safety department.

6. Methanol is flammable, do not use in the presence of open flame or ignition sources.PREREQUISITES

1. Each tool coming in contact with sampling media or any other potent.ally contaminated surface: must be decontaminated prior to the collection of the next sample.2. The type of sample being collected will determine which tools and materials are needed. Given below is a list of suggested tools and materials to choose from: Site map Chain of custody forms (DPF-8123.1)

Field Log Book Location marking supplies, e.g.. spray paint and stakes 50 or 100-foot tape measure* Digging implements, e.g., :trowel or shovel Soil auger Soil core sampler Sample containers, e.g., "ZipTop" plastic bags or paint cans Plastic bags (approx. 10 gal- size) for vegetation collection

SAMPLING CONTAINERS, PRESERVATION REQUIREMENTS, AND HOLDING TIMES FOR SOIL AND LIQUID SAMPLES The type of sample container, volume required for analysis, and the maximum holding time for various constituents and media are) presented in Appendix A.B. SOIL and SEDIMENT SAkMPLING NOTE: These sampling techniques are not appropriate for soil and sediment collected for Volatile Organic Analysis (VOC) .In addition, stainless steel tools or equivalent are to be used for the collection of samples for nonradiological analysis.1. if soil is under a paved area or concrete floor, remove the asphalt or concrete.a. If an asphalt sample is to be collected, perform Section C before proceeding to step B.3.b. If a concrete sample: is, to be collected, refer to* Reference

1. -2. If required, cut vegetation to approximately the soil surface level, and remove any uiitte'n nthe ground sur-face (e.g., stones or dead/dry sticks and leaves that are not part of the soil humus layer).NOTE: If desired, cut vegetation may be saved for a separate* analysis.

In such a case, cut the vegetation over a measured area (e g. 7 one square meter), recording that area in the Field Log Book and place in a plastic bag.3. Using a new or decontaminated (according to Section H of this procedure) stainless steel or equivalent tool (i.e.trowel, shovel, hand auger, etc.), remove soil or sediment at the selected sampling location (or locations for composite sampling) to the desired depth. DP-8120 Rev. 7 NOTE: Ideally enough soil should be collected to provide for a one liter sample after preparation.

NOTE: For soil samples collected outside of the Owner Controlled Area, dig a straight-sided hole with measured surface dimensions (e.g., 6" x, 6-) and record in the Field Log Book.4. Place the sample into the appropriate container as specified in Appendix A. Ensure sufficient sample has been collected.If additional soil or sediment is required due to the number and volume of samples that must be collected, obtain the soil or sediment from a location immediately adjacent to the first by following steps 1 through 3 as necessary and remove a similar amount of sample.I b. Composite samples collected for nonxadiological analysis should be mixed in a stainless steel bowl or ziptop plastic bag.5. Large sticks or rocks greater than approximately three inches in size should be:discarded while digging the sample, unless otherwise instructed.

Compensate for the lost volume at that depth by collecting additional sample from the same depth as the discarded rock/stick.

uOTE: Where a large rock(s) prevents the collection of an adequate sample, th4&sampling point should be moved slightly to allow a better sample. In such a case, the movement and its- reason should be noted in the Field Log Book.NOTE: Sticks and rocks less than three inches in size must remain in the sample. They will typically be removed at the laboratory during the sample preparation stage.Their weight will be accounted for at that time.6. if required by Appendix A, preserve samples accordingly.

7. Close the container to loss of material.8. Label the container with the sample identification number (or bar code label), date of collection, time of collection, type of analysis (if non-rad), preservation method (if non-rad), and sampler's initials.9. Ensure that the sample is secure and that the appropriate sample custody documentation (if required) is completed in accordance with DP-8123 [2j as soon as practicable.

C. ASPHALT SAMPLING-1C0=: Ideally enough asphalt should be collected to provide for a one liter sample after preparation.

1. Using a hammer drill or denolition tool (with the appropriate bit), a cold chisel, or any other appropriate tool, cut a circular hole in the asphalt through its entire thickness.

2. Break up the asphalt sample into small pieces with the hammer drill.

-5 DP-8120 Rev. 7 NOTE: Be careful when breaking up the asphalt pieces with a power tool so that excessive mixing of the asphalt rubble with the upper layer of soil does not occur.3. Remove the asphalt pieces, taking care to minimize any dirt to the pieces. Place in a suitable container.

4. If required by Appendix A, preserve accordingly.

5. Close the container.

6. Label the container with the sample identification number (or bar code label), date of collection, time of collection, and sampler's initials.7. Ensure that the sample is :secure and that the appropriate sample custody documentation (if required) is comhpleted in accordance with DP-8123 [2) as soon as practicable.

D. LIQUID SAMPLING 1. Using the appropriate sampIe collection container as identified in the Table in Appendix A, collect the sample-directly into the container without pre-rinsing from the liquid.2. Submerge the lip of the sample container below the liquid surface, filling the container until a slight headspace is present. Remove from the liquid and cap.3. Samples collected for volatile organic analysis (e.g.VOC, pesticides) must contain no headspace or air bubbles after capping. To collect these samples: a. Collect the sample in a separate unused container.

b. Pour the water to the appropriate container using a continuous stream into a pre-preserved container; do not overflow.the container is full and a meniscus is present, cap the container and turn the container upside down and inspect for bubbles.d. If bubbles are presefnt, remove cap and add sample to re-establish meniscus prior to capping. Repeat as necessary.

4. If required by Appendix A, preserve accordingly if not previously provided..5. Label the container with the sample identification number, dlate of collection, time 6"T collection, and sampler's initials-6. Ensure that the sample is -secure and that the appropriate sample custody documentation (if required) is completed in accordance with DP-8123 [2! as soon as practicable.

DP-8120 Rev. 7 E. IDENTIFICATION OF SAMPLING POINTS i- If not already described in a sampling plan, describe the location of the sampling site in the Field Log Book by one of the following means:-Distance measurements to two or more structures (or other identifiable points)-Detailed drawings Reference to a grid coordinate system* Global Positioning System {GPS) measurements

-Any other equivalent method.2. :Mark the sample location with a semi-permanent marker (e.g., wood stake) when one of the methods in step 1 can not be used to identify the sample location.3. A revised sample location code for radiological samples will ,:be effective with Rev 7 of this procedure.

The Safety Oversite Manager or designee will assign the first nine characters in the Location Code for each survey unit material listed using Table 1, Survey Location Codes and Appendix B, Survey Area Description, as guidance.

The Location Code is composed of a 12 character alpha numeric string as follows: Characters 1-5 = Survey Ar-a Identification Character 6 = Survey Unit Code Character 7 = Survey Unit Classification Code Character 8 = Survey Type.Code Character 9 = Material Code Characters 10 -12 = Survdy Point F. SAMPLING SOIL, ASPHALT, AND CONCRETE FROM EXCAVATION STOCK PILES 1. STOCK PILE SEGREGATION AND IDENTIFICATION:

a. Ensure that individual piles of soil, asphalt, and concrete are segregated on the following bases: 1) Area of excavation

-Soil, asphalt, and concrete excavated from any single area should be kept segregated from other piles until final disposition.

Any pile consolidation must be documented.

2) Type of material -Soil should be segregated from asphalt, concrete should be segregated from soil or asphalt. Other materials (e.g., wood.rebar, metals,ý'or construction debris) are not addressed in this procedure and should be separated from~the soil, asphalt and concrete.3) Contamination potential

-Any soil, asphalt, or concrete or suspected to be contaminated should be segregated; placed onto a poly tarp and sampled separately.

This may be based on site characterization or other survey results.or on knowledg6 of the area's previous activities.

Since site characterization surveys DP-8120 Rev. 7 have shown that soil contamination in the RCA is generally limited to the top six inches, initially, the top six-inch layer approximately should be segregated and sampled separately when excavating within the RCA.b. The Safety Oversite Manager or designee will assign a unique number to each soil, asphalt, or concrete stock pile, log the number and other pertinent information on form DPF-8120.!, "and provide the num-ber to the RP Technician performing the sampling.A revised pile numbýering system will be effective with Rev. 7 of this procedure.

The new system will consist of a 14 digit field starting with a P, designating Pile; followed by a 4 digit field for the year; a five digit field for the survey Area ID code; a two digit field for pile type (TS for soil, AS for Asphalt, CT for concrete);

and a two digit sequential pile number.This method retains all of the features of the old system while adding the Survey Area ID so that the pile number identifies the origin of the excavated material.For example;P20000G021TS04 is the fourth soil pile from survey area 0G021 assigned in year 2000 P2000OG021AS01 is the first asphalt pile from sur-vey area 0G021 assignedrin year 2000 NOTE: Form DPF-8120.1 will be controlled by the Safety) Oversite Manager or his designee.c. Prepare a suitable map to identify the location of each pile. Label the map with the pile number.d. Write the pile number (obtained from the Safety Oversite Manager or designee) on two wooden stakes (with a Sharpie or other indelible pen) and drive the stakes solidly into the pile (front and back)e. Cover each pile with a tarp to minimize the migration of potential contamination due to the forces of wind and rain, etc.f. Where a pile is pladed on a slope, place bales of hay or silt fence on the down-slope side to catch any run-off.2NOTE: -In the event that piles are moved, the Safety Oversite Manager or designee shouild be notified so that the pile's location can be tracked, and to ensure thai the pile is clearly labeled in its new location.

The new location should be noted on Form DPF-8120.1.

2. SA4PLING FROM AN EXISTING PILE: a. If the pile is large enough to make access to the inner volume of thehpile difficult, split the pile into two or more sub-piles (e.g., with a backhoe) to)allow access.

DP-8120 Rev. 7 b- Collect approximately 30 samples of' at least 100cc each, placing the samples into a plastic bag (more than one (1) plastic bag will be needed). In addition to the pile's unique number the plastic bags will be numbered "l of ##" i.e., I of 2, 1 of 6, etc.NOTE: A roughly determined grid should be used, and a shovel should be used to allow sampling at varying depths. The goal is to systematically (i.e., uniformly) sample throughout the entire pile volume. Use a Hilti drill as necessary to break up the asphalt and concrete into small pieces. Every effort should be made to ensure that one third of the samples collected are from the surface of the asphalt being excavated.

c. During sampling of soil piles, remove and return to the pile rocks and sticks greater than approximately V inch in size. For asphalt and concrete samples, such rocks bound up in the asphalt or concrete may be removed later during sample preparation.

NOTE: If any large man-made objects are encountered during sampling (e.g., barrel rings, sheet metal), remove them from the pile for separate monitoring. (Monitoring and disposition of this material is outside the scope of this procedure).

7 3. SAMPLING DURING EXCAVATION:

a. By talking to the excavating contractor, determine how often samples need to be collected to achieve 30 samples from each excavation/pile.

A "pile" will consist of no more than approximately 15 cubic yards of soil, asphalt, or: concrete.NOTE: Multiple "pilets" may result from a single excavation, ba'sed on the criteria in F.l.b. At the frequency determined above, collect individual samples at least 100cc each directly from the bucket, placing all of these samples in a plastic bag (more than one (1) plastic bag will be needed). In addition to the stock pile's unique number the plastic bags will be numbered " l'of ##' i.e., 1 of 3, 1 of 5, etc.NOTE: When the excavation is completed, 30 or more samples should have been collected from each stock pile- If not, collect enough additional samples from the stock pile (sample uniformly through the pile's volume) to achieve 30 samples.-During sampling, rernbve and return to the pile rocks and sticks greater than approximately

' inch in size.For asphalt or concrete samples, such rocks bound up in the asphalt or cc:%crete may be removed later during sample preparation..'

NOTE: If any large man-made objects are encountered during sampling (e.g., barrel rings, sheet metal) , remove them from the pile for separate monitoring. (Monitoring and disposition of this DP-8120 Rev. 7 material is outside the scope of this procedure).

G_ SAMPLE DOCU4ENTATION AND HANDLING 1. If the samples are part of site characterization:

a. Record all appropriate information in the Field Log Book. As a minimum, include: Sample date-Samole time -* Sampler's name(s)Sample location identification code/pile number Sufficient description and/or measurements to allow the sampling site to be identified in the future.map of area excavated and pile placement as appropriate.

ýb. Any deviations from this procedure that are forced by field conditions (e.g., large rocks or ledge obstructing sampling, etc.) should be noted here.c. Record sampling information on DPF-8120.1 and DPF-8120.2 as appropriate.

2. If the samples are in support of site release, record sampling information in accordance with AP-0052 [101 .3. Deliver or arrange delivery of the samples to the designated sample prep or storage location, the DE&S Environmental Lab (DESEL) or another off-site analytical facility.a. Ensure that a tamper evident seal is affixed to each sample container.

Seals shall be initialled and dated by the preparer.b. For samples submitted to the DESEL, complete form YELF 605.1 and send it with the samples.c. Fill out a chain of custody form in accordance with DP-8123 [2].Contact the Radwaste Coordinator for the shipment of any sample(s) containing plant-related radioactivity to any off-site facility.'P. DECONTAMTNATION OF EQUIPMENT NOTE: Decontamination is performed in three stages, generally by using three buckets as described below. The same method may 5e used in a sink, it available, as long as the same three-step process is used and the drain line is suitably connected for radioactively contaminated waste. The first container is used for removal of gross residue and scrubbing with detergent.

The second container, half-filled with clean water, is used for the first rinse. The third container, initially empty, is used to collect the rinsate from a spray bottle, and is generally used only in areas where DP-8120 Rev. 7 contamination is suspected.

Determine in advance whether the decontaminated tool is to be sprayed with methanol as a final step (non-radiological analysis only).1. Set up three 5-gallon containers as follows: a. The first container is half filled with water and a small amount of laboratory grade detergent (such as Alconox).b. The second container is half-filled with clean water.c. The third container is initially empty. (This* container is not needed in areas where contamination is not suspected, e-g., outside the Radiological Control Area.)2. Don a new pair of latex, nitrile or equivalent gloves.3. Remove any gross residue from the sampling tool, letting the material (e.g., soil) fail into the hole from which it was ,sampled.

If the sampled hole is not immediately available, save the material for appropriate waste disposal.

If the tool had last been used outside the Owner Controlled Fence,.the material may simply ftll onto the ground.4. Place the used sampling tool in the first container and scrub with a brush.5. Remove the tool from the first bucket and place the tool in the second bucket. Scrub with another brush.6. Holding the tool over the third container (or over the ground if in an area where contamination is not suspected, e.g., outside the Radiological Control Area), completely rinse the tool with a squirt bottle of Methanol or clean water.7. Wrap the cleaned tool in new aluminum foil.8. Remove the gloves and dispbse of appropriately.

9- Place the decontamination-ý.Huids into a container labeled"Decontamination Waste". "Disposal should be based on a representative sample and :analysis of the water, or as prescribed by the Radiation Protection Department.
