FINAL EFFLUENT POND SLUDGE SAMPLING AND ANALYSIS PLAN 

I. Overview 

To provide a comprehensive sludge sampling strategy ofthe Final Effluent Pond (PEP), a twophase sampling plan is proposed. 

Phase 1 Will collect sludge from four representative locations in each pond and analyze the 

samples for the comprehensive list ofchemical compounds and other analytical parameters 

shown in Table 1. The analytical parameter list includes the 40 Code ofFederal Regulations 264 

Appendix IX (Groundwater Monitoring List) analytes for the metal, volatile organic compound 

(VOC), semivolatile organic compound, polychlorinated biphenyl, and dioxin/furan groups. 

Excluded from the analyte list because ofprocess knowledge are the herbicide and pesticide 

groupings of compounds. Three additional compounds from the 40 Code ofFederal Regulations 

Appendix vrn (Hazardous Constituent List) are included based on process knowledge: dibutyl 

phthalate, acetone, and formaldehyde. Other analytical parameters will include total oil and 

grease, fluoride, cyanide, total sulfide, water content, corrosivity, and igni~bility. 

The Phase 1 testing will include analyses for both (a) total concentrations and (b) toxicity 

characteristic leaching procedure (TCLP)-extractable concentrations. Past sampling ofthe 

sludges has shown them to have a high water content. Therefore, chemical concentrations will ( be reported on a wet-weight basis. 

In addition to the standard TCLP extraction, one Phase 1 sample from each pond will be 

subjected to extract testing at two additional pH values. The multiple pH extract testing will 

follow the recommendations in the EPA RCRA Delisting Program, Guidance Manual for the 

Petitioner, March 2000. Besides the standard extract described in TCLP Method 1311, the 

sludge will be extracted at two other pH values and analyzed. The two alternate extract fluids 

will be: 

• . Distilled deionized (OI) water 

• An alkaline solution ofsodium hydroxide with a pH between 10 and 12. 

The Phase 1 samples for the multiple pH extractions will be collected from the sampling location 

that is anticipated to have the greatest sludge thickness. Exhibit 7-A presents the map ofpond 

sediment (i.e., sludge) depth determined in a 1993 study ofthe FEPs. 

The TCLP extractions and the multiple· pH extractions will be analyzed for all constituents, 

except total sulfide, total oil and grease, and the Resource Conservation and Recovery Act 

(RCRA) characteristics ofignitability and corrosivity. Note that organics that are not detected in 

the total analyses do n~t need to be analyzed in the TCLP and multiple .pH extracts. 

Phase 2 will collect samples from more numerous locations that are randomly selected according 

to the method recommended for surface impoundments in EPA RCRA Delisting Program,

/' 

Guidance Manual for the Petitioner, March 2000. The Phase 2 samples will be analyzed for a 

subset of analytes to be detennined by the Phase 1 results, as described in Section IV.C. 

II. Sampling Locations 

The plan for sampling the FEP sludges is to collect a sufficient number ofsamples using an 

unbiased approach to characterize the material in the ponds. The sampling plan accounts for 

potential vertical and horizontal variability in the sludge. Horizontal variability is accounted for 

in the sampling strategy of each pond, as described later in this section. 

Vertical variability ofthe sludge will be addressed by taking a representative sample from the 

full thickness ofsludge at each sampling location. Volatile organic compounds (VOC) will be 

analyzed on a subsample taken from the middle portion ofthe sludge core. The remainder ofthe 

core will be homogenized and sampled for the other analytical parameters. 

_A. . Phase 1 Sampling Locations 

To obtain a representative sampling of each pond for the Phase 1 analysis, a systematic sampling 

approach will be used. Each pond will be divided into four approximately equal surface areas, 

and the center of each area will be sampled. The total number ofsamples will be eight, four 

from FEPI and four from FEP2. The sludge from each sample location will be analyzed as an 

independent sample. 

B. Phase 2 Sampling Locations 

B.1 Phase 2 Overview 

Sample locations for Phase 2 are selected using the random sampling selection process for 

surface impoundments as described in EPA ReRA Delisting Program, Guidance Manual for the 

Petitioner, March 2000. 

First, the total area of each pond is detennined. Secondly, each pond is divided into equal 

sampling sections ofless than or equal to 10,000 square feet (sq ft) (FEPI will be divided into 7 

sections and FEP2 into 6 sections). Thirdly, each 10,000-sq-ft section-is divided into a grid of 

~quares or rectangles roughly 10 feet on each side. Finally, a random number table is used to 

select four squares for sampling within each section. 

Each ofthe four locations within a section will be sampled for sludge, and the four sludge cores 

from each section will be compo sited into a single sample for analysis (except for VOCs). The 

resulting number ofsamples for analysis will be 7 from FEPI and 6 from FEP2. 

However, ifVOC analysis is necessary in Phase 2 (depending on the Phase 1 results), then a 

single sample from the middle of each sludge core will be submitted for VOC analysis. In this 

case, there will be 28 samples fQr VOC analysis from FEPI and 24 from FEP2, in addition to the 

7 samples from FEP 1 and 6 from FEP2 that are given full analysis.

B.2 Determination of Surface Area 

( 

FEPI is of an irregular shape, and its surface area is 68,500 sq ft. FEP2 is rectangular, and its 

approximate surface area is 54,800 sq ft. Plan views and surface area calculations for the FEPs 

'are presented in Exhibit 7-B. 

B.3 Determination of Sampling Sections 

FEP1 is divided into seven (7) 1O,000-sq-ft sections. Due to the irregular shape ofFEP1, the 

surface area ofthe sections varies from approximately 9,559 to 9,853 sq ft. The sampling 

section layout for FEP1 is presented in Exhibit 7-C. 

FEP2 is divided into six (6) equal sections, each having a surface area of9,133 sq ft. The 

sampling section layout for FEP2 is presented in Exhibit 7-D. 

c. Determination of Phase 2 Sample Locations 

Each ofthe sampling sections is divided into squares or rectangles (hereafter referred to as 

"squares") approx-imately 10 feet on a side. Due to the irregular shape ofsome sections ofFEP1, 

some ofthe squares varied from 10 feet in size. The squares are consecutively numbered from 1 

to 100, beginning in the northwest comer ofthe section and proceeding east, then south. 

The random number table presented in EPA ReRA Delisting Program, Guidance Manual for the 

Petitioner, March 2000, is used to randomly select four squares for sampling within each section. ( The table is presented in Exhibit 7-E. Sampling points will be located in the centers ofthe 

squares. 

Each ofthe sampling points selected using the random number table was assigned a 

unique coordinate address, measured in feet to the east and to the south from the northwest 

comer ofthe pond to the center ofthe square selected by the random number table (e.g., [S3, E7] 

is the point 7 feet east and 3 feet south ofthe northwest comer ofFEP2, the center of square 01 

ofSection 1 ofFEP2, selected by the random number table for sampling). 

C.l FEPI 

FEP1 has 28 Phase 2 sampling locations. The sampling location layout for FEP1 is presented in 

Exhibit 7-C. Table 2 presents the coordinates for the Phase 2-sampling locations at FEPI. 

C.2 FEP2 

FEP2 has 24 Phase 2 sampling locations. The sampling location layout for FEP2 is presented in 

Exhibit 7-D. Table 3 presents the coordinates for the Phase 2 sampling locations at FEP2.

Ill. Sample Collection - Phases 1 and 2 

The sludge-sampling method described in this plan is the same that was used for the 1993 study, 

except no samples for VOC analysis were collected in the previous work. 

A. Field Health and Safety 

The most recent revision to the site-specific health and safety plan prepared for the RCRA 

corrective action program at the Mt. Athos site will be used to guide implementation ofthe 

sample collection activity (Site-Specific Health and Safety Planfor BWX Technologies, Inc, Mt. 

Athos Facility, Lynchburg, Virginia, August 6, 2003). Prior to the fieldwork: the health and 

safety plan will be reviewed to ensure that it addresses hazards particular to the work described 

in this sampling plan. 

B. Sampling Rig and Navigation Method 

A sampling rig will be fabricated from two boats positioned in opposing directions, stem to 

stem, clamped together using lumber and "c" clamps to give a working length ofapproximately 

26 feet for the equipment and two sampling technicians. A rope aligned in a north-south 

direction will be strung across the pond to pull the vessel to the designated sample locations. 

To guide the boat rig, rows ofpin flags spaced 50 feet apart will be set up, aligned north-south 

and east-west along the pond sides. . 

C. Sampling Equipment and Preparation 

Samples will be taken using new, clear polycarbonate tubes with a wall thickness of 1116 inch. 

A typical tube diameter is 2-5/8 inches, but other diameters may be used. A cap or stopper will 

be used to seal the sample tube after each sample is taken. 

The polycarbonate sampling tubes will be decontaminated prior to collecting samples. Personnel 

will wear new latex gloves when handling samples or sampling equipment. Sampling tubes will 

be prepared as follows: 

• DI water rinse 

• Liquinox® soap solution wash 

• DI water rinse, twice 

• Dilute nitric acid solution rinse 

• Final DI water rinse 

• Air dried and wrapped in aluminum foil. 

4 

BWXT - FEP Delisting Petition 6/10/04 

D. Sample Handling Area 

( 

A work area will be established to decontaminate the sampling equipment and to prepare and 

process the samples for transport to the laboratory. The area will include separate tables for 

sample collection preparation and sample processing, DI water, cleaning chemicals, a container 

for solid waste, and a vessel for liquid waste. The solid waste will be disposed of as dry, lowlevel radioactive (LLR) mixed waste, and the liquid waste will be treated at the LLR Waste 

Treatment Facility. 

E. Sampling Method 

Sludge samples will be collected as follows: 

1. 	 At each sample location, the polycarbonate tubing will be pushed through the sludge 

layers and twisted forcefully into the clay layer on the bottom ofthe pond. The stiff clay 

will serve as a plug to keep the sample in the tube and as a visual confinnation that the 

base ofthe sludge is reached. 

2. 	 Ifthe sludge is thin at all four sampling locations within a section, then more than one 

sludge core will be collected from each ofthose sampling locations, to obtain enough 

material to perform all the analyses on the composited sample. In such case, the same 

number of cores will be collected from all four sampling locations within a section, and 

all the tubes will be composited (this is to ensure that the final composite is representative 

ofthe sludge throughout the section). See Table 11 for sample volumes and QC sample 

requirements. 

3. 	 A cap or stopper will be inserted on the top end ofthe sample tube to serve as a seal to 

retain the sample as the tube is withdrawn from the bottom ofthe pond. The tube 

containing the sample will be lifted at an angle to reduce the downward pressure on the 

column. 

4. 	 The sample tube will be held over the side ofthe boat, and the outside ofthe sample tube 

will be rinsed with DI water. The sample end cap will be wrapped with heavy 

polypropylene tape to ensure that the sample will not fall out ofthe tube during handling. 

5. 	 The sample tubes will be numbered in accordance with the pond number and the 

coordinates, as previously presented. 

6. 	 Immediately after sample collection, the total sludge depth will be measured, including 

measurements of any stratification in the sample. The sludge will be described for color 

and any other visual characteristics, looking through the polycarbonate tube wall. The 

total sludge depth and description will be recorded on a Sample Collection Log. A hole 

will be drilled in the sample tube at the top ofthe sediment layer to allow the water 

column above the sample to weep out ofthe rube. The sludge description may be 

annotated the following day, after the frozen sludge core is extruded from the tube and 

the vac sample is containerized, as the sludge may be more easily_examined then. 

5

BWXT - FEP Delisting Petition 6110/04 

( 7. The sample tubes will be wrapped with new aluminum foil at the top end. The bottom 

end will be secured with a plastic end cap that will be taped in place. 

8. The sample tubes will be moved to the sample handling area and frozen. 

F. Sample Preparation 

The sample tubes will be frozen overnight as described later in this section. The next day, the 

frozen cores will be extruded (pushed) from the tubes. Previous experience with sampling the 

FEP sludges found that the frozen cores are not hard, but rather slushy. 

Sample aliquots for VOC analysis will be cut or cored from the frozen cores and placed in the 

appropriate sample containers. The remaining portions ofthe four frozen cores from each pond 

section will be combined. The combined samples will be thawed and homogenized before they 

are placed in the sample shipping containers. 

Table 4 lists the sample containers, preservation requirements, and holding times for the various 

analytical parameters. 

The sample freezing system will consist oftwo (2) 55-gallon open head drums, several pieces of 

6" polyvinyl chloride (PVC) pipe cut in lengths slightly longer than the sample tubes and capped 

at one end, and dry ice pellets. The PVC pipe sections will be placed into a new 55-gallon drum 

and the sample tubes will be lowered into the PVC pipes in groups ofthree (3) or fewer. Dry ice 

pellets will be poured into the spaces between the sample tubes until the PVC pipes are full and 

the sample tubes are completely covered. A second drum will be inverted and placed over the 

bottom drum. Both drums will be wrapped in plastic sheeting and taped to prevent air from 

coming into contact with the dry ice, which will help insulate the freezing system. The samples 

will be left in the dry ice overnight to ensure that they will be frozen before being cut into layers. 

To prevent tampering while the samples are left overnight in the drums, custody tape seals will 

be placed across the overlapping edges ofeither the drums or the plastic sheeting. The custody 

"seals will be initialed and dated by one ofthe sampling team members. 

The next day, the sample tubes will be removed from the PVC pipes to process the samples for 

submission to the laboratory. The exterior surface ofthe frozen sample tube will be sprayed with 

DI water to slightly thaw the sample for removal from the tube. 

As soon as the sludge is extruded from the sampling tube, the sample aliquot for VOC analysis 

will be removed from the middle ofthe sludge core and p"laced into the appropriate container. 

Sample aliquots for VOC analysis will be removed from the frozen sludge by coring, such as 

with a cork borer or with an EnCore® sampler. The coring device will be selected to closely 

match the diameter ofthe VOC vial orjar container, and thus minimize headspace in the 

container. The frozen sludge will be cored in lengths that are longer than the VOC container(s), 

and the end will be trimmed as needed to cap the container. The VOC sample container will be 

. filled completely to minimize headspace.

I 

BWXT - FEP Delisting Petition 6/10/04 

The remainder ofthe four cores from each 1O,OOO-sq-ft section will be placed in a new 

aluminum pan, or other suitable, cleaned metal container. The combined sludges will be thawed 

and then homogenized within the container by stirring with a cleaned utensil. Aliquots ofthe 

homogenized sludge will be placed in the appropriate sample bottles. 

After each sample is bottled, a custody seal will be placed across the sample container lid. 

The sample containers will be placed in coolers with ice to maintain a temperature of4 degrees 

Celsius C<>C). A temperature blank will be included in each cooler for the laboratory to monitor 

the temperature in the cooler upon receipt. 

Samples for VOC analysis will be delivered to the laboratory the same day they are removed 

from the cores. Other samples preferably will be delivered to the laboratory the same day also; 

but ifthey are held overnight, then the coolers will be kept in a secure, locked location. 

Custody ofthe samples will be maintained following the chain-of-custody procedures in the 

BWX Technologies, Inc. (BWXT), Data Collection Quality Assurance Plan (DCQAP), which is 

presented in Exhibit 7-F. . 

G. Field Documentation 

The sludge sampling activities will be documented on the following kinds offield forms: 

• Field Daily Activity Log 

• Sample Collection Log 

• Chain ofCustody Form. 

Examples ofthese forms, and how they are used, are included in the DCQAP, Appendix F, 

which is being issued as a separate document: 

The daily narrative ofthe fieldwork for the sludge sampling will be documented on Field Daily 

Activity Logs. Each sludge tube or other sample collected will be documented on a Sample 

Collection Log. The Sample Collection Log will provide the following information about the 

sample: pond identifier (ID), sample location ID, number oftubes collected at the sampling 

point, sludge depth and description, collection of additional material for quality control (QC) 

samples, and any comments or observations. All samples sent to the laboratory for analysis will 

be accompanied by a chain-of-custody form, which will also include the request for analysis. 

IV. Sample Analysis 

A. Analytical Laboratories 

It is anticipated that the entire laboratory analyses, except dioxins/furans and oil and grease, will 

be performed by the BWXT Services Nuclear Environmental Laboratory. Dioxins/furans will be 

7 

BWXT - FEP Delisting Petition 6/10/04 

( 


analyzed by Eno River Labs ofOurham, North Carolina. Oil and grease will be analyzed by 

Severn Trent Laboratory-St. Louis, Earth City, Missouri. The current certificates of 

accreditation for the laboratories are presented in Appendix G as part ofthe OCQAP. 

If another laboratory is used for some ofthe analyses, that laboratory shall be accredited by the 

National Environmental Laboratory Accreditation Program for the analyses the laboratory will 

perform. 

B. Phase 1 Analytical Parameters 

< 

The parameters to be analyzed in the Phase 1 sludge samples are listed in Table 1. The specific 

analytical methods and the laboratories' standard reporting limits for the various parameter 

groups are listed in Tables 5 through 10. 

C. Phase 2 Analytical Parameters 

After the Phase 1 analysis results are completed and compiled, a summary will be provided to 

the U.S. Environmental Protection Agency (EPA). To provide a cost-effective and 

comprehensive sampling analysis for Phase 2, a telephone conference call or meeting will be 

held with the EPA to determine the final list of analytes for the Phase 2 sludge samples. It is 

anticipated that the Phase 2 samples will be analyzed for a significantly shorter list of analytes. 

v. Quality Control Samples - Phases 1 and ·2 

QC samples will be collected and analyzed to verify the integrity ofthe sampling and analytical 

program. The types ofQC samples that will be collected and their general collection frequencies 

are described below. 

A. Trip Blanks 

Trip blanks are applicable only to samples being analyzed for VOCs. The blanks are prepared in 

the laboratory using laboratory-grade 01 water. The blanks are transported to the site and back 

to the laboratory without being opened until the site samples are analyzed. One trip blank will 

accompany each cooler that contains samples to be analyzed for VOCs. The trip blank will be 

analyzed for VOCs along with the sludge samples that it accompanied from the field. 

B. Temperature Blanks 

A temperature blank consists of a tap water sample in ajar kept in the cooler along with the site 

samples. A temperature blank will be placed in each cooler to verify that samples received by 

the laboratory are at 4°C, plus or minus 2°C. The laboratory will measure the temperature ofthe 

blank upon receipt ofthe cooler. 

Observ.ed blank sample temperatures greater than 6°C will be noted in the laboratory analytical 

report. For VOC samples received at 6 to lOoC, the data usability will be evaluated and a 

decision will be made whether to continue with analysis or recollect samples. Resampling will 

8 

BWXT - FEP Delisting Petition 6/10/04 

occur ifVOC samples show a temperature blank greater than 1 <rC. The data validation process 

( 	 will judge the usability ofthe corresponding data depending on the observed temperature and the 

susceptibility ofthe particular analytical parameter to degradation under elevated temperature. 

c. Equipment RiDsates 

Equipment rinsate samples will be collected during sampling to verify the effectiveness of 

sampling equipment cleaning and to monitor for potential to inadvertently transport constituents 

ofinterest between samples. Equipment rinsates will be collected from the final DI water rinses 

ofthe polycarbonate sampling tubes or the sludge homogenization containers (sequential rinsate 

samples will alternate between the two). One rinsate sample will be collected for every 20 

sludge samples, or two per sampling event (e.g., sampling phase), whichever is greater. The 

rinsate samples will be analyzed for total concentrations of all the chemical parameters. 

D. Field Blanks 

Field blanks will be prepared in the field from the source ofthe DI water used for cleaning. 

Analysis of field blanks will ensure that all water sources used during cleaning ofsampling 

equipment are free ofthe parameters ofinterest. One field blank will be collected per day and 

analyzed for total concentrations of all the chemical parameters. 

E. Field Duplicates 

Field duplicate samples ofthe sludges will be collected. The aliquots offield duplicates for ( VOC analysis will be collected from adjacent positions on the same sludge core. Field duplicate 

aliquots for the other analytical parameters will be collected from the homogenized sludge. A 

minimum ofone field duplicate will be collected for every 20 sludge samples, or one per 

sampling phase, whichever is greater. Field duplicates will be analyzed for the same parameters 

as the other sludge samples. 

F. Matrix Spike and Matrix Spike Duplicate Samples 

Separate field samples will be collected for the laboratory matrix spike/matrix spike duplicate 

(MSIMSD) analyses. MSIMSD samples are described in the DCQAP. One pair ofMSIMSD 

samples will be collected for every 20 sludge samples, or one per sampling event, whichever is 

greater. 

VI. Sample Quantities 

Table 11 lists the estimated numbers ofsludge samples and QC samples and the sample 

containers fo~ the Phase 1 sampling. 

VII. Data Validation 

The analytical data will be validated by Shaw Environmental, Inc., in accordance with the EPA 

Region mInnovative Approaches to Data Validation (June 1995). The validation will evaluate 

9 

BWXT - FEP Delisting Petition 6/10/04 

the laboratory analytical reports and the associated field documentation to detennine whether the 

sampling and analytical method requirements are achieved. The analytical data generated will be 

analyzed for precision, accuracy, completeness, representativeness, and comparability. 

The minimum acceptable completeness goal for Phase 1 will be 7 out of 8 sample analyses, 

except for the mUltiple pH extractions, for which 100 percent completeness is required. If 

necessary, more samples will be taken and analyzed to generate a data set that is acceptably 

complete. 

The completeness goal for Phase 2 will.be at a minimum of90 percent.

1. All samples from four locations in each pond will be tested for all parameters, except only one sample from 

each pond will be subjected to multiple pH extractions. 

2. Analyses will include the following constituents not included in 40 CFR 261 Appendix VIII: acetone, 


ethyl benzene, isophorone, 4-methyl-2-pentanone, styrene, and xylenes (total). 


3. If the total chromium content exceeds one percent, then analyze for hexavalent chromium by Method 7196A. 

4. If the content of oil and grease equals or exceeds one percent, then extractable metals will be determined 

using the Oily Waste Extraction Procedure SW-846 Method 1330) in lieu of TCLP extraction. 

5. If no total cyanide is detected, then it is unnecessary to analyze for TCLP-extractable cyanide. 

6. OrganiCS that are not detected in the total analyses do not need to be analyzed in the TCLP extracts. 

7. TCLP extraction for cyanide will use deionized water as the leaching fluid. 

8. TCLP analyses for all constituents using two extraction fluids other than the standard TCLP extraction fluid: (1) 

distilled deionized water; and (2) NaOH solution of 10<pH<12. This is described in the EPA RCRA Del/sting 

Program Guidance Manual for the Petitioner, March 2000, Appendix H, Elements of the Region 6's Evaluation 

Process, 8Attachment 4, Multiple pH Test Protocol, at www.epa.gov/earth1rt>/6pd/rcra clpd-o/dlistpdthtm.

Notes: 

1. Analytical results will be reported on a wet weight basis. 

2. If the total chromium content exceeds one percent, then analyze for hexavalent chromium by method 7196A. Note that the soil holding time for hexavalent chromium analysis is 28 days. 

3. If the content of oil and grease equals or exceeds one percent, then extractable metals will be determined using the Oily Waste Extraction Procedure (SW-846 method 1330) in lieu of 

TClP extraction. 

4. If no total cyanide is detected, then it is unnecessary to analyze for TClP-extractable cyanide. 

5. Organics that are not detected in the total analyses do not need to be analyzed in the TClP extracts. 

6. TClP extraction for cyanide will use deionized water as the leaching fluid. 

7. 1# 12# days means 1# days until TClP extraction, 2# days from TClP extraction until determinative analysis. 

8. 1# 12# 13# days means 1# days until TClP extraction, 2# days from TClP extraction until preparative extraction, 3# days from preparative extraction until analysis. 

9. TClP analyses for all constituents using two extraction fluids other than the standard TClP extraction fluid: (1) distilled deiOnized water; and (2) NaOH solution of 10<pH<12.
