Inc Naval Nuclear Fuel Division February

6, 2001 ADMINISTRATIVE REVIEW

OATE1.0 introduction This plan outlines the proposed Groundwater Monitoring Plan for Final Effluent Ponds

1 and

2 at BWX Technologies,

Inc. (BWXT) Naval Nuclear Fuel Division

at the Mt. Athos Site in Campbell County near Lynchburg,
VA. The intent of this Plan
is to support the delisting

of the Final Effluent Ponds (FEPs) under the requirements

of 40 CFR 260.22. The groundwater monitoring
will be carried out to determine

if any hazardous waste
or hazardous waste constituents from the FEPs have impacted
the groundwater

in the area. 2.0 FEP Description The Final Effluent Ponds are located north and east of the wastewater treatment plant. FEP

1 has

a 1.2 million-gallon capacity and FEP

2 has

a 1.8 million-gallon capacity. FEP

I was placed

in service

in 1973 and received wastewater from both the low-level radioactive (LLR) and pickle acid treatment systems until 1979. Both waste streams are neutralized

via separate systems and the precipitation solids are removed

by filtration. Suspended solids from both neutralization operations

are carried over into the FEPs.
In 1979, FEP

1 was drained and approximately

50 percent
of its sludge was placed into FEP 2. From 1979
to 1992, FEP

1 received wastewater from the pickle acid and sanitary treatment processes. From 1979
to present, FEP

1 has received wastewater from the imhoff treatment process. FEP

2 received LLR wastewater from 1979 to present, and pickle acid wastewater from 1992 to present. In November 1990, The Virginia Department

of Environmental Quality classified
the pickle acid waste stream

as
a chemical etching/milling operation. Consequently,

the neutralization sludges generated from treatment were classified

as EPA Hazardous Waste No. F006. Both FEPs have received wastewater from the pickle acid system and suspended solids from the neutralization operation have been deposited

in each pond.

It should
be noted that current generation

of this sludge has been delisted
by USEPA and Virginia DEQ. 3.0 Groundwater Monitoring System The groundwater monitoring system currently

in place consists

of one upgradient well and three wells immediately downgradient

of the FEPs. The monitoring well locations are shown
on Figure

1. The groundwater flow has been established (from

a previous RCRA Facility Investigation)

to be flowing

in a northeasterly direction towards the James River. Borings
for the monitoring wells were drilled using hollow-stem auger methods.

A borehole diameter

of 7 1⁄4 inches was drilled

to install the 2-inch schedule

40 PVC casing and screen. The 0.0 10 inch slotted screen was installed

at a depth, where lithology permitted, from approximately

10 feet below the water table
to
5 feet above the water table. The screened portion
of each well was packed with

a sand pack.
A 1-foot hentonite seal and

a 2-foot cement grout seal were then added, completing

the well to the ground surface. The wells were completed with aboveground locking steel protective casings and six feet square concrete pads. Monitoring well construction diagrams
are included

in Appendix

I. The boreholes were logged from the drill cuttings according

to the UnifiedSoil Classification System. These logs are included

in Appendix

IL All well installations were supervised
and verified
by
a certified geologist from The IT Group. 4.0 Sampling and Analysis The groundwater monitoring program will include consistent sampling and analysis procedures
that are designed

to ensure monitoring results that provide

an accurate representation

of the groundwater quality

at the background

and downgradient wells. Field sampling and laboratory analysis will be conducted

in accordance with the BWXT Data Collection Quality Assurance Plan to meet the requirements

set forth in EPA document SW-846. The general activities and technical approach that will be followed are discussed

in the following sections. Additional details are provided

in the Data Collection Quality Assurance Plan (Appendix
III). Field data will be documented

to meet record keeping requirements. 4.1. Well Preparation The groundwater monitoring wells
to be sampled
are FEP

1, FEP2, FEP3, and MW-I 7A as shown

in Figure

1. Each well will be purged
of stagnant water prior
to sampling. Purging will be performed with

a Teflon

or stainless steel pump,
or Teflon

or stainless steel bailer. The purging equipment shall be cleaned before and after the sampling

of each well. All wastewater produced during the purging and sampling operations shall be processed through the NNFD waste treatment system. Wells will be purged until

a minimum

of three (3) casing volumes

of water have been removed. Wells that are determined

to be low recharge wells (i.e., wells that cannot recharge

80 percent
of the original volume within

8 hours) will be purged until 100 percent
of the original well volume has been removed. Water samples
for chemical analysis will be collected within 24 hours of purging operations. 4.2 Sample Collection Groundwater samples will be collected

by means
of a dedicated bladder pump,
or clean stainless steel or Teflon bailer. All monitoring wells will be sampled
for the 40 CFR 264 Appendix

IX constituents identified

in Table

1. New polypropylene

line will be used for each well. After purging, the first water sample obtained will be tested
in the field for pH and temperature. Subsequent samples
for laboratory analysis will be collected

at a slow flow rate to minimize agitation and aeration and preserved

as specified

by the SW-846 method for each analyte. Chain of custody forms will be prepared, and samples will be labeled and stored
in a cooler with adequate
ice until delivery

to the laboratory

at the end of each day. The temperature

of contents

of the cooler will be noted
as equilibrium

is reached

to ensure 4°C storage.

24.3 Cleaning Procedures All equipment used for groundwater sampling, well purging, and well development activities will be washed with laboratory-grade detergent, rinsed with tap water, rinsed with laboratory grade methanol,
and rinsed with deionized water and allowed

to air dry. The cleaning area shall be lined with plastic and shall have raised edges
to contain
all cleaning solutions and material dislodged from equipment during cleaning operations. The materials collected

at the cleaning area shall be placed

in labeled drums and disposed of in accordance with BWXT’s waste management procedures. 5.0 Quality Assurance
and Quality Control The data collection strategy and the means

to achieve the objectives

of the compliance sampling
are described

in detail
in the BWXT Data Collection Quality Assurance Plan (DCQAP).
The DCQAP provides details for the following requirements
that apply
to the compliance sampling effort: • Intended uses for the data • Precision, accuracy, representativeness,

and completeness • Data comparability • Quality assurance (QA) reports and schedules • Analytical data quality levels. Data quality levels that will be needed for this compliance sampling include Level

1 (field screening

or analysis using portable instruments),

and Level

3 (analyses performed in an analytical laboratory). Sample analysis will conform

to standard operating procedures

of the BWX Services laboratory following analytical methods from EPA specified

in SW-846 (3’ ed.) (EPA, 1986). All constituents
will be analyzed using one of the suggested SW-846 methods identified

in Table

1. All sample analysis procedures
and requirements

are specified

in detail
in the DCQAP. The DCQAP provides details for the following requirements
that apply
to the compliance sampling effort: Laboratory sample receipt • Instrument calibration • Analysis procedures • Laboratory quality control (QC) checks • Data documentation • Calibration standards logbook • Data reduction, validation,
and reporting • Evaluation

of method, trip, and field blanks. and matrix spikes • Evaluation

of precision, accuracy, and completeness • Surrogate spike response evaluation. To ensure the reliability

of field sampling procedures
and materials, field QC samples will be collected

or prepared. The following paragraphs describe the QC samples that will be collected during implementation

of this plan. 35.1 Trip Blanks Trip blanks are defined

as samples that originate from laboratory-grade deionized water taken from the laboratory

to the sampling
site and returned

to the laboratory with the VOC samples. One trip blank shall accompany each cooler containing samples

to be analyzed
for VOCs, shall be stored with the samples

at the laboratory,
and shall be analyzed

by the laboratory
(for VOCs only). 5.2 Equipment Rinsates Equipment rinsates will be collected during sampling

to verify the effectiveness

of sampling equipment cleaning and to monitor
for potential

to inadvertently transport constituents

of interest between samples. Equipment rinsates will be collected from the final deionized water rinses of the equipment.
One rinsate will be collected from each site. The rinsates will be analyzed
for the same analytes

as the samples collected that day. 5.3 Field Blanks Field blanks are prepared from the laboratory-grade-deionized

water used for cleaning. Analysis

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

of sampling equipment

are free of the parameters

of interest.

At
a minimum,
one sample will be collected
for every sampling event day and analyzed
for VOCs. 5.4 Field Duplicates Duplicates

for samples will be collected simultaneously
with the original samples. For each sample type, one field duplicate will be collected during the field event. To meet the analytical
QC requirements,

the field duplicates will also be selected

as the laboratory matrix spike/matrix spike duplicate pair and the laboratory duplicate sample. Therefore, at least four times the minimum required sample volume will be collected and four different analyses will be performed:

the original sample, the field duplicate,
the laboratory matrix spike, and the laboratory matrix spike duplicate

or 1abortory duplicate. 5.5 Field Equipment Calibration Field instrument calibration

is required

to maintain accuracy

of the instruments

for conducting field screening, measurements,

and health and safety monitoring. Calibration readings and procedures
will be recorded. Field instruments
will be calibrated

as stipulated below; operations manuals
for all instruments
will be maintained

on site with the sampling equipment: • pH meter- Calibration

as specified

by the manufacturer,
prior
to each shift or break. • Specific conductance meter- Calibration

as specified

by the manufacturer, prior
to each shift or break

4• Thermometer

- Calibration

as specified

by the manufacturer; factory set. • PID/FID

- Calibration

as specified

by the. manufacturer,

at the start of each day’s activities and during the day as situations warrant. • Electronic water level meter

- Calibration

as specified

by the manufacturer; factory set, and returned
for calibration every
12 months. 5

EPA U.S. Environmental Protection Agency vii1.0 Data CoHection Strategy The data collection strategy and the means

to achieve the objectives
are described

as follows:

• Scientific data will be of sufficient

or greater quality

to meet scientific and legal scrutiny • Data will be gathered

or developed

in accordance
with procedures appropriate

for the intended use of the data • Data will be of known and acceptable precision, accuracy, completeness, representativeness,

and comparability. Fundamental mechanisms
that will be employed

to achieve these quality goals can be categorized

as prevehtion, assessment,

and correction. These include: • Prevention

of errors by planning, documented instructions
and procedures,
and careful selection and training

of skilled, qualified personnel • Quality assessment through

a program

c-f audits and surveillances

to supplement continual informal review • Correction

for prevention

of recurrence

of conditions adverse

to quality. The DCQAP has been prepared

in direct response

to these goals. This plan describes
the QA program

to be implemented

and the quality control (QC) procedures

to be followed

by BWX Technologies (BWXT) and its contractors during the course any sampling events conducted

at the BWXT Mt. Athos site.- 1,1 intended Uses for the Data Data obtained from any sampling event may be used
to characterize

the site’s environmental setting, define and characterize

the nature and extent
of the potential release

of hazardous waste
or hazardous constituents from the areas
of investigation

at the site, identify actual
or potential receptors,
and perform

a risk assessment.

Ill- Analyses performed

in an analytical laboratory. 1.2 Precision, Accuracy, Representativeness,

and Completeness QA objectives have been established

for precision, accuracy, representativeness,

and completeness

for each major measurement parameter

for the BWXT Mt. Athos site. These objectives
are documented

in the laboratory QAJQC manuals and in this DCQAP. Data will be calculated
and reported

in units consistent with the SW-846,
3rd ed. analytical procedures to allow for comparability. Definitions

for and means

of assessing precision, accuracy, completeness, representativeness,

and comparability

are described below: • Precision- A measure

of agreement among replicate measurements

of a sample. Comparison

of replicate values

is expressed

as the relative standard deviation (RSD). • Bias- Consistent deviation

of a measured value from the true value caused
by
a systematic error

in procedure. • Accuracy- The degree

of agreement

of a measurement

(or an average

of replicate measurements),

X, with an accepted reference

or true value,

T, usually expressed as the difference between the two values, X-T, or the difference

as
a percentage

of the reference

or true value, 100 (X-T)/T, and sometimes expressed

as
a ratio, XIT. Accuracy

is a measure

of bias and precision. Accuracy

is assessed through the analysis

of spiked samples, known standards,
and reference samples. • Completeness- A measure

of the amount

of valid data obtained from

a measurement system compared

to the amount that was expected

to be obtained under correct normal conditions. This QA criterion

is expressed

as
a percentage. The completeness

for sample collection
will be 95 percent

or better.
The data completeness

will be 100 percent
for residential well samples and 90 percent or better for other types
of samples. • Representativeness- Expresses
the degree

to which data accurately
and precisely represent

a characteristic

of a population, parameter variations

at a sampling point, :1-3a process condition,

or an environmental condition. Representativeness

is a qualitative criterion that
is associated with the proper design

of the sampling program. Data highly representative

of this site will be achieved through

a systematic
site evaluation
and comprehensive sampling plan. If it is deemed that previous sampling, analytical,

or QAIQC procedures

did not conform with currently accepted requirements,

the discrepancies

will be noted and the data from the previous investigations)

will be qualified accordingly. 1.3 Data Comparability One of the objectives

of the DCQAP

is to provide analytical data of comparable quality between sample locations and with data from previous investigations. ComparahiUty

is a qualitative criterion measuring

the confidence with which one set of data can be compared

to another. For this project, the data comparability

will be achieved

by the following: • Analytical results will be reported

in appropriate units: ugll and mg/I for aqueous samples, and mg/kg for soil samples. • The same
or similar sampling procedures used

in previous investigations

will be used. • The same
or equivalent analytical procedures used for previous investigations

will be used. • Similar QAIQC requirements

will be observed. The BWXS—NEL’s quality assurance

is documented

in NELS-QAP, N&EO QIP, and the NELS TP. The plans and standard operating procedures have been used by BWXT

to conduct the sampling and analysis from previous investigations

and ongoing quarterly sampling. BWXT has also used outside laboratories

to provide confirmatory

and support analyses. The same sample collection techniques
and analytical procedures

will be used
to maximize
the comparability

of data with previous investigations. Additionally,

to enhance comparability between samples, consideration

will be given
to seasonal conditions, stream flow, or other environmental conditions that could influence
the analytical results. 1-4IA QA Reports and Schedules Periodically, audits
of QA activities
will be performed. AudIt reports will be submitted

to the Manager

of Environmental Engineering

at BV’IXT NNFD who will ensure that audit findings are resolved consistent with the requirements

of the audit program. 1-5Table 1-1 Analytical Data Quality Levels Data Use Technique Appropriateness

the site and/or characterize

the extent
of impacted soil. Samples
not selected
for laboratory analysis will be stockpiled with the drill cuttings. The site geologist
will maintain

a detailed boring log during the drilling
of each borehole. The log will serve as
a record
of sample collection, sarnple location and depth, and drilling procedures. All soil cuttings generated during the drilling
of soil borings will be stockpiled

on plastic sheeting, bermed, and covered with plastic sheeting within the study area where the borings were drilled. Upon receiving
the laboratory analytical results from the samples collected from the borings, the disposition

of the soils will be determined. Those soils found

to be above regulatory action limits for any of the constituents

of analysis will be disposed

of in compliance
with state and federal regulations. Those soils found
to be below action limits will be spread across the ground surface

in the area where the borings were installed. 22.1 Field Screening

of Soil Samples If filed screening

is deemed necessary,
the 5-foot sample barrel from the boring will be placed
on clean plastic sheeting and the barrel split open. The entire length
of the sample will then be scanned
for the presence

of organic vapors using an HNu or similar photoionization device. The depth interval and reading

in units of parts per million will be recorded
for any portion

of the sample where organic vapors are detected. The sample will also be visually observed
for any signs
of alteration

or contamination

and the observations noted. The measurement

of volatile emissions

or significant visual observations

will serve
as
a qualitative indication

of potential contamination. In areas
of known

or suspected acid releases,
soil samples
will be collected and submitted

for laboratory measurement

of pH. Low pH readings
will serve
as
a qualitative indicator

of acid impacted soils. 2-22.2.2 Soil Samples

will be packed

in coolers with ice for delivery

to the laboratory. Physical parameters

of the sediment
will be described

on

a sample collection
log. All sampling equipment

will be properly cleaned before collecting samples and between sampling locations. Sediment samples taken from ponds will be collected using

a clamshell type scoop, such as an Eckman Dredge

or similar sampling device. The sampler will be used
to collect

a sample from the upper sediment layer by the following procedure: • Sample line will be attached

to the pre-cleaned Eckman Dredge. • The distance from water surface

to bottom will be measured
and marked

so that the equipment-lowering

rate can be reduced, thus preventing unnecessary bottom disturbance. • The sampler jaws will be opened
by attaching
the support cables

to the messenger tripping mechanism. • The free end of the sample line will be tied to
a fixed support

to prevent accidental loss of the sampler. • The sampler will be lowered more slowly
as the bottom depth approaches. • Once contact with the bottom

is made, the sample line will be slackened

to allow the sampler

to penetrate
into the sediment. • The messenger, which slips around the sample line, will be released and will trigger the closing

of the dredge. • The dredge wiJI slowly be raised

to the surface. • Using

a stainless steel spoon, the sample will be removed from the dredge and placed inside an appropriate sample container. Samples collected
will be handled

as described

for stream sediment samples. The sampler
will be thoroughly cleaned between sampling events. 2-42.4 Monitoring Well Installation 2.4.1 Drilling Methods All shallow monitoring wells installed above the bedrock surface will be drilled using
7- 114-inch outside diameter hollow-stem augers.
All borings
for the installation

of bedrock monitoring wells will be drilled using an air rotary drilling rig. Bedrock borings win be advanced using

a 9-1/4inch-drill

bit. Upon encountering bedrock,

a temporary casing will be placed

in the boring

to prevent the sidewalls from collapsing. Boreholes for the installation

of surficial aquifer wells will be drilled approximately

10 feet below the water table. Deep wells
to be completed

in bedrock will be drilled

5 to 10 feet into the bedrock, and a 6-1/4inch-diameter polyvinyl chloride (PVC) casing will be installed and grouted into place. The grout will be allowed

to solidify for no less than 24 hours. This procedure will be followed

to prevent potential mixing

of the surficial and bedrock aquifer waters. After 24 hours, the well will be drilled

to total depth through the 6-1/4-inch casing using a 6-inch drill bit. A boring log will be prepared

for each well to describe the lithology encountered.

All PVC casing will conform

to the requirements

of ASTM-F480-81, D1785.
All PVC screen and casing construction joints shall be flush threaded.

No glued
or solvent welded joints shall be permitted. • Cuttings generated during the driiiin

of borings for the intaliation

o monitoring wells may be field screened

for the presence

of organic vapors using an HNu photolonization device. Those cuttings exhibiting organic vapors will be stockpiled

on plastic sheeting, bermed, and covered with plastic sheeting. All water and fluids generated during the drilling and completion

of the wells will be contained
and disposed

of by being pumped into the pickling wastewater treatment system

at the Naval Nuclear Fuel Division (NNFD) plant. 2-52.4.2 Well CompletionV Shaflow monitoring wells installed above bedrock,

or to a maximum depth
of 100 feet below the bedrock surface, will be completed with 2-inch Schedule

40 Pvc solid riser and machine-cut screen with 0.01 0-inch slots. The wells will be screened across the water-bearing
zone using

a 15-foot length
of well screen. The annulus around each well screen will be backfired with clean, well-graded silica sand using

a tremmie pipe. The sand pack will extend

to approximately

2 feet above the well screen.

A 2-foot layer of bentonite pellets will be placed directly above the sand pack. Bentonite pellets will be emplaced with

a tremie pipe
in wells deeper than 30 feet, and

a tamping device used
to pack the pellets

in wells less than 30 feet deep. The remainder

of the annulus will be filled with

a bentonite/cement
grout. The wells will be finished with concrete pads and locking caps. Monitoring wells installed within the bedrock aquifer will be drilled

5 to 10 feet into the bedrock, and

a 6-1/4-inch permanent PVC surface casing will be grouted into place. The grout will be allowed

to solidify for no less than 24 hours. This procedure
will be followed

to prevent the mixing

of surficial and bedrock aquifer waters. After the grout has solidified,
the boring will be drilled

to total depth through the surface casing. Monitoring wells drilled

to depths greater than 100 feet below the bedrock surface will be completed

as open holes below the surface casing without well casing.
AllV shallower wells wifl be completed witn WC!i casing
as specified ac The WOS Wii be finished with concrete pads and locking well caps. 2.4.3 Well Development Each newly installed groundwater monitoring
well will be developed

no sooner than 24 hours after completion.
The wells will be developed

by pumping. Surging

of the pump will be performed during well development

to prevent bridging. The well pump shall be properly cleaned before

it is inserted

in any well, as specified

in Section 2.7. Development water will be pumped into 55-gallon drums and labeled. The drums will

Surface Water Sampling Sampling

of surface waters shall be performed using the following procedures. Grab samples
will be obtained using

a
I -liter Teflon beaker

or sample vial. Beakers will be thoroughly cleaned before use and after each sample point with an Alconox and potable water wash and deionized
(Dl) water rinse. Samples collected with beakers will be transferred

to the sample container with minimal agitation and aeration. Field measurements

for pH, conductivity,

and temperature

will be made
at each sample location. Field QC samples
will be obtained

as described

in Section 2.9.1. 2.7 C’eaning Procedures All drilling equipment
that may contact the interior

of the borehole,

as well as all well completion materials, shall be thoroughly steam-cleaned

in a clean area free of contamination designated

by the field coordinator. After steam cleaning,

all equipment will be washed with

a laboratory-grade detergent, followed

by
a Dl water rinse. Drilling equipment

will be thoroughly decontaminated

and inspected between each drilling location.

All equipment used for groundwater

and soil sampling, well purging, and well development (including aquifer testing) will be washed with laboratory-grade detergent, rinsed with tap water, rinsed with laboratory grade methanol, and rinsed with Dl water and allowed

to air dry. The cleaning area shall be lined with plastic and shall have raised edges

to contain

all cleaning solutions and material dislodged from equipment during cleaning operations.
The materials collected

at the cleaning area (drill cuttings,
soil sample debris, and other potentially hazardous solid waste) shall be placed

in labeled drums and disposed

of in accordance
with state and federal guidelines. Pre-cleaned bottles will be used for all analyses. Sample bottles will be cleaned according

to standard EPA procedures

for each analysis type. 2-112.8 Field Documentafion 28.1 Field Activity Daily Logs Field data collection activities
will be recorded

on
a number

of field logs. Entries will be described

at an appropriate level of detail
so that the situation can be accurately reconstructed.

All log sheets will be kept
in the BWXT project files or the NELS project files as appropriate. Entries
on the logs may contain

a variety
of information.

At the beginning,
the date, start time, weather conditions,

all field personnel present, level of personnel protection being used on site, the signature

of the person making the entry, and other details will be entered

as specified. The names

of visitors

to the site and the purpose

of their visit may be recorded.

All entries will be made

in permanent

ink; no erasures
will be allowed.

If an incorrect entry

is made, the information

will be crossed out and initialed. Measurements made and samples collected
will be recorded. Equipment used
to make measurements

will be identified, along with the date of last calibration. Samples will be collected following
the procedures documented

in this pan. The equipment used
to collect samples will be noted, along with the time of sampling,
the sample description,

the depth

at which the sample was collected,
and the volume and number of containers

in which the sample was placed

in the field. Results

of any gas or vapor monitoring activities
will be recorded. Major activities being performed

or other items pertinent

to the history
of the investigation

will also be noted. 2.8.2 Boring Logs The site geologist
will maintain

a detailed boring log during the drilling

of each borehole. The log will serve
as
a record
of sample collection, sample location and depth, and drilling procedures.
The boring log will include: 2-12• Heading information including project number, site number, boring number, personnel responsible

for logging the hole, ground elevation and coordinates,
and date boring was started and completed • Depths

of samples recorded

in feet and tenths
of feet • Detailed soil descriptions including: • Ma ci soil component • Secondary components

and estimated percentages • Classification • USCS symbol • Color • Consistency

of Custody The CCC procedures

are intended

to document sample possession from the time of collection

to disposal,

in accordance
with federal guidelines. Sample collection and coc

in the field will be documented

in the field activity logs and on
a COO form as shown

in Figure 2-1. This COO form will indicate the analyses required
for each sample

as specified

by the project plan. While

in the laboratory,
the CCC information for all samples
will be recorded

on the laboratory’s internal CCC forms. The criteria for maintaining custody requires that thioughout

the sampling and analysis process the samples and associated paper work are controlled

in a manner designed to prevent unauthorized tampering that could affect reported results while providing

a traceable record
of sample handling.
2-142.9 Quality Assurance
and Quality Control 2.9.1 Field Quality Control Samples To ensure the reliability

of field sampling procedures
and materials, field QC samples will be collected

or prepared
for each medium sampled, each sample shipment, and each sampling event. This field investigation

will be considered
one event unless field personnel leave the site for more than 24 hours during the course

of the investigation. The following information defines and describes how to identify and document
QC samples.

All field samples will be given unique sample numbers. 2.9.1.1 Trip Blanks Trip blanks are defined

as samples that originate from laboratory-grade

Dl water taken from the laboratory

to the sampling
site and returned

to the laboratory with the volatile organic samples. The trip blank monitors potential cross contamination

of the samples
for volatiles during handling and shipment. One trip blank shall accompany each cooler containing samples

to be analyzed
for VOCS, shall be stored

at the laboratory with the samples, and shall be analyzed

by the laboratory.
Trip blanks only need
to be analyzed
for VOCS. Trip blanks shall be identified with

a unique number and the prefix

‘ 1 TB’ on the sample bottle and COO 2.9.1.2 Equipment Rinsates Equipment rinsates will be collected during soil and groundwater sampling

to verify the effectiveness

of sampling equipment cleaning and to monitor
for potential cross contamination between samples. Equipment rinsates are collected from the final Dl water rinses
of the equipment cleaning process. One equipment rinsate will be collected from each site. The rinsates will be analyzed
for the same analytes

as the 2-15

# samples collected that day. Equipment rinsates Will be identified with

a unique number and the prefix “ER’ on the sample bottle and coc. 2.9.1.3 Field Blanks Field blanks are prepared from the laboratory-grade

Dl water used for cleaning. Analysis

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

of sampling equipment

are free of the parameters

of interest. Only water field blanks are required.

At
a minimum, one sample will be collected every other day of multi-day sampling events

or one sample collected during single day sampling events. Field blanks will be analyzed
for all parameters. Field blanks will be identified

by
a unique number and the prefix “FB” on the sample bottle and COO. 2.9.1.4 Field Duplicates Duplicates

for samples will be collected simultaneously

with the original samples.
For each sample type, field duplicates
will be collected
for at least 10 percent

of the samples collected during the field event.

A minimum

of one duplicate
will be collected per sample type. To meet the analytical
QC requirements,

at least half of those samples selected

as field duplicates
will also be selected

as the laboratory matrix spike duplicate (MSD) pair or the matrix spike (MS) sample and laboratory duplicate sample for
a total of
5 percent

of the field samples. Therefore,

for half of the field duplicates,

at least four times the minimum required sample volume will be collected and four different analyses
will be pcrformed:

the original sample,the
field dulicate... the laboratory
MS, and the laboratory MSD
or laboratory duplicate.
For the remainder of the field duplicates,
two times the normal sample volume will be collected

to provide the original and the duplicate samples. Field duplicates

will be identified with unique sample numbers. The two samples collected

as laboratory
QC samples will also be identified with unique sample numbers. 2.9.2 Field Equipment

of temperature,

pH, and specific conductance

will be performed on water samples

at the time of sample collection. The water level will be measured

in monitoring wells before purging, immediately before groundwater samples are collected.

An additional measurement

of water levels

in all monitoring wells will be made

in a single 24-hour period. This will ensure that comparable water levels will be collected from each well and represent

an “instant’

in time. The temperature

of each water sample will be measured using

a temperaturemonitoring device traceable

to National Institute
for Standards
and Technology (NIST). The pH of each water sample will be measured using

a portable
pH meter. The meter will be calibrated with buffer solutions

of the appropriate range for expected values

of pH. The meter calibration
will be checked

at regular intervals. The specific conductance

of each water sample will be measured with

a portable field conductivity meter.

A standard potassium chloride solution will be used
to calibrate the instrument before

it is used. Meter calibration

will be checked regularly. Field measurements made during purging and sampling operations

will be entered

in the fkld logbook.

as part of instrument usage, such as the development

of a standard curve for use with an atomic absorption spectrophotometer. Operational calibration

is generally performed

for instrument systems

as part of the standard operating procedure. • Periodic calibration: Performed

at prescribed intervals
for equipment, such as balances and ovens.

In general, equipment items that can be calibrated periodically

are distinct, single-purpose
units and are relatively stable

in performance Procedures published

by ASTM, the U.S. EPA,
or procedures provided

by manufacturers

will be utilized. At
a minimum,
the procedures shall include: • Calibration technique
and sequential actions • Calibration documentation format • Reference standards used for calibration • Acceptable performance tolerances • Frequency

of calibration. Documentation

of calibration shall be kept for each equipment item with project files or laboratory equipment files. 4.3 Analysis Procedures

for Soil, Groundwater, Surface Water, and Sediment Samples Inorganic and organic analyses
will be performed

as specified

in the SW-846,
3rd ed., using standard laboratory operating procedures. These include QAIQC requirements, holding times, data qualifiers, and data reporting format. 4.4 Laboratory Quality Control Checks Laboratory

QC checks are used
to validate data integrity. Analytical quality controls are related

to batches

of semples

a specified

in SW-846 and the NELS QAP. These 4-3controls include reagent blanks, QC check samples, duplicate samples, and spiked duplicates each batch
or every 20 samples. Initial and continuing calibrations shall be performed

at intervals

as referenced

in appropriate SW-846 methods and NELS technical procedures. Calibration standards must be reference quality, traceable

to NIST, and purchased from an approved supplier.
QC check samples shall be evaluated against the acceptance limits as specified

in the appropriate SW-846 methods and the NELS technical procedures. Surrogate spikes for organics shall also be evaluated against the acceptance limits
as specified

in the appropriate SW-846 methods and the NELS technical procedures. 4.5 Documentation

of Data Documentation measures encompass

all analytical and QC activities ensuring
the integrity and validity

of sample analysis results and providing

a traceable history

of each sample analysis. Information

is recorded

on worksheets, analytical logbooks,

or computer data systems. System support information such as instrument maintenance and equipment calibration records are kept
in laboratory files. Component analytical documentation measures included
are summarized

in the following sections 4.51 Laboratory Sample Receipt Logbook All samples submitted

to NELS for laboratory analysis are assigned

a unique SDG Number and each container/bottles

is labeled with

a unique identifier.

All relevant information regarding
the origination
and receipt

of the samples

is recorded

in the NELS’s electronic Sample Tracking System. Examples

of the types
of individual entries include: analyses requested, date/time

of coflection, receipt conditions,
and the filed identification number. 4.5.2 Laboratory Worksheets The analytical specifications

and subsequent results

of each sample submitted

to the laboratory
are recorded

on various laboratory worksheets included

in standard operating procedures. Pertinent information

on the worksheets includes laboratory sample identification, requested analytical parameters, maximum holding times and 4-4turnaround requests, and analytical results. Laboratory worksheets

will be kept on file at the laboratory. 4.5.3 Laboratory Method Logbooks Data generated during the analysis

of samples

by NELS

is recorded and documented according

to the NELS QAP and governing technical procedures.
The systems

of documentation employed

by NELS allow for complete traceability

of all the data generated during the course

of analysis. 4.5.4 Calibration Standards Logbook All laboratory primary standard data are maintained

in a laboratory standards logbook. Working standards
are documented

in analysis records with traceability

to the primary standards. 4.5.5 Instrument Computer Data System Files Chromatography

and atomic absorption spectroscopy
data files are maintained according

to sample log number. The data files include instrument parameters, calibration data, date of analysis, analyst, and QC results. 4-55M Data ReductionNaiidationiReporting Validation

is the process

of determining whether

a measurement system provides useful analytical data. Adequate sample identification

and chain-of-custody procedures verify the integrity

of the sample. Validation

of the analytical method

is accomplished through instrument calibration with traceable standards
and collaborative testing such as blind performance evaluation (PE) and daily QC samples. Raw data entries are validated

by the analyst with

a signature, date, and time of analysis. The sample data packages include relevant information such as sample identification, chain-of-custody, measurement methodology, instrument identification, calibration data, analyst signature (with date and time of analysis), and demonstration

of statistical control with method blanks, field and trip blanks, replicates,

QC samples, and spikes (surrogates

for organics).
The laboratory supervisor

or designee oversees data collection and reduction

to verify that data

is converted

to meaningful reporting values. Consideration

in data reduction must be given
to significant figures for each analysis, method detection limits, precision

of duplicate results, and the accuracy

of QC data. Reporting

of lab data by computer

is validated

by signature

of a cognizant individual. Reports will include sample identification,
final sample results, and QC information. 5.1 Data Assessment Protocol When the analyses

of a sample set are completed,

the results are reviewed and evaluated

to assess the validity

of the data set. Review

is based
on the following criteria. 5.1.1 Sampling and Field Information The sampling requirements

are defined

in the sampling plan. Field data are recorded in field logs and may include

as appropriate;
well installation,
field conditions, well water sampling, field instrument calibrations,
and field measurements. 5..5.1.2MethodBlankEvaluationWhenappropriateforthemethod,areagentand/ormethodblankshouldbeanalyzedwitheachbatchofsamplesprocessedtoassesscontaminationlevelsinthelaboratory.Theresultsoftheblankshouldbelessthanthelaboratory’sreportinglimitfortheanalyte.Iftheblankresultsdonotmeettheacceptancecriteriaabove,thenthelaboratoryshouldtakecorrectiveactiontolocateandreducethesourceofthecontaminationandre-extractandreanalyzeanysamplesassociatedwiththecontaminatedblank.5.1.3FieldandTripBlankEvaluationFieldandtripblankresultsareevaluatedforhighreadingssimilartothereagentand/ormethodblanksdescribedabove.Ifhighfieldblankreadingsareencountered,theproceduresforsamplecollection,shipment,andlaboratoryanalysisshouldbereviewed.Ifboththereagentand/ormethodblanksandthefieldblanksexhibitsignificantbackgroundcontamination,thesourceofcontaminationisprobablywithinthelaboratory.Highfieldblankreadingsmayalsobeduetoairbornecontaminationorcrosscontaminationduetosampleleakageandpoorlysealedsamplecontainers.5.1.4MethodCalibrationEvaluationWhenevaluatingcalibrationstandards,thecalibrationcurveisevaluatedtodeterminelinearitythroughitsfallrangeand.tpverifyth?tsamplevaluesarewithintherangedefinedbythelowandhighstandards.Ifthecurveisnotlinear,samplevaluesmustbecorrectedfornonlinearitybyderivingsampleconcentrationsfromagraphorbyusinganappropriatealgorithmtofitanonlinearcurvetothestandards.Calibrationsareverifiedusingbothinitialandcontinuingcalibrationcheckstandards.Acceptabilityofthecalibrationisbasedonthecriteriasetforeachanalyticalmethod.5-25.1.5 Evaluation

of Analytical Precision Duplicate sample analysis
for the sample set is used
to determine
the precision

of the analytical method
for the sample matrix. Precision limits are derived statistically

by the laboratory.

If the precision value exceeds the acceptance criterion
for the given parameter

in question,
the reason for the nonconformance
must be determined; corrective action may include reanalysis. MS/MSD pairs may also be assigned. The results

of the duplicate analyses
are used to calculate
the RPD, which

is the governing
QC parameter

for precision. The RPD for replicate analyses

is defined

as the absolute difference (range)

of each replicate set, divided
by the average value (mean)

of the replicate set, times 100 percent. For replicate results,

D, and D2, the RPD

is calculated

as follows: RPD— IDI-0211 xlOO% (Di+D 2)/2 5.1.6 Evaluation

of Analytical Accuracy In addition

to the evaluation

of analytical precision,
the laboratory
will evaluate accuracy.

To determine
the accuracy

of an analytical
the results

of MS, MSD, and blank spikes are used
to calculate
the QC parameter

for accuracy evaluation,

the %R. The %R
is defined

as the observed concentration, minus The sample concentiaticn, divided
by the true concentration

of the spike, times

1 00 percent:01.02 %R xlOO% T 1 where: %R= Percent recovery Ci= Observed spike sample concentration02= Sample concentration

5-3Ti True concentration

of the spike Final review

of the data
to be reported

is provided

by the laboratory supervisor.
The laboratory supervisor

is then responsible

for ensuring that the final reports are reviewed before release. Reports are reviewed
for: • Completeness- Results for all parameters requested
are present; detection limits, units, dates, and sample descriptions

are complete and correct. • Consistency- All parameters

are reviewed
for internal consistency. • Accuracy

of data entry. 5t7 Matrix Spike Evaluation To evaluate
the matrix effect
of the sample upon the analytical methodology, samples are spiked with compounds appropriate

for the method. The
% recovery

of those compounds from the sample

is monitored.. Recovery limits are statistically established

for each method.

If the % recovery

is outside the acceptance range,
an evaluation

of the cause
of the deviation

is undertaken.

If it is determined
that the analytical system was out of control then the samples
will be reanalyzed. 51.8 Reference Standard Evaluation Standard reference materials analyses
are compared with true values and acceptable ranges. Values outside the acceptable ranges require corrective actions to determine
the source

of error and to provide corrective action.
All sample analyses should
be halted pending this evaluation. Following correction

of the problem,
the standard reference material should
be reanalyzed. 5.1.9 Surrogate Spike Response Evaluation Surrogate standard determinations

are performed

on samples and blanks. Samples and blanks are fortified with surrogate spiking compounds before purging

or extraction to monitor preparation
and analysis

of samples. 5-4Surrogatespikerecoverymustbeevaluatedforacceptancebydeterminingwhethertheconcentration(measuredaspercentrecovery[%R])fallsinsidetherequiredrecoverylimits.Ifrecoveryisofwithinsurrogaterecoverylimits,thefollowingactionsaretaken:•Checkforerrorsinthecalculations,internalstandardorsurrogatespikingsolutions.Examinechromatogramsforinterferingpeaksandintegratedpeakareas.oCheckinstrumentperformance.Correctanyproblemsandre-analyzetheextract.-•Ifnoinstrumentproblemisfound,thesampleshouldbere-extractedandreanalyzed.•If,uponreanalysis,therecoveryisagainnotwithinlimits,thedatawillbequalifiedaccordingly.Iftherecoveryiswithinthelimitsinthereanalysis,providethereanalysisdatatothedatauser.Ifthemeasureslistedabovefailtocorrecttheproblem,theanalyticalsystemmustbeconsideredoutofcontrol.Theproblemmustbecorrectedbeforecontinuing.Thmaymeanrecalibratingtheinstrumentationbutitmayalsomeanmoreextensiveaction.Thespecificcorrectiveactionshouldbedefinedbythegchromatogmph(GO)operatorwiththeconcurrenceofthelaboratorysupervisorand/orinstrumentmaintenancespecialist.Reportthesurrogatespikerecoverydataandthesampledatafrombothextractionswhenreanalysissubstantiatesamatrixeffect.5.2DataCompletenessCompletenessiscalculatedasthepercentoftotalusabledatapointsoutofthesetoftotaldatapointscollected,analyzed,andavailable.Datapointsmaynotbeusableifsampleanalysistimeexceededholdingtimes,orifQCsamplecriteriawerenotmet5-5andreanalysisofsamplesisnotpossible,orifsamplecontainersweredamagedduringshippingorinthelaboratory.Completenesscanbecalculatedasfollows:0=100DlJ/DTwhere:C=CompletenessDu=UsabledatapointsDT=Totaldatapointscollected5.3DataReportingFormatFinalreviewofthedatatobereportedisperformedbytheappropriatelaboratorypersonnel.Reportsarereviewedfor:•Completeness-Resultsforallrequestedparametersarepresent;detectionlimits,units,dates,andsamplelOsarecompleteandcorrect.•Consistency-Allparametersarereviewedforinternalconsistency.•Accuracyofdataentries.Thelaboratorysupervisororprojectmanagerisresponsibleforensuringthatthefinalreportisreviewedpriortorelease.Preliminaryordraftanalyticalreportsmaybeprovidedforthoseprojectsrequiringrapidanalyticalturnaroundtimes.Theseabridgedmaterialsprimarilycontainanalyticalresults.Additionalsupportingmaterialsmaybeprovidedifprearranged.Preliminaryreportswillbefollowedbyfinalreports.Laboratoryanalyticalfinalreportsmayincludeappropriateintroductorycomments,analyticalmethodssummaries,andQCreportsinadditiontolistingsampleanalyticalresultsandassociatedQCdata.Sampleanalyticalresultreportsheetsaregeneratedinhardcopyand/orappropriatecomputerformat.Additionaltechnicalnarratives,5-66.0PerformanceandSystemAuditsToverifycompliancewithDCQAPrequirements,theBWXTQAprogramadministratororhisdesigneewillperformauditsofprojectactivities.Auditresultswillbeformallydocumentedandsenttothe!3VVXTprojectmanager.Inaddition,thereportwillbedistributedtothefieldoperationsmanager,samplingandanalysiscoordinator,andtheITtechnicalmanager.Auditsmayinclude,butnotbelimitedto,thefollowingareas:•FieldoperationworkproceduresandrecordsLaboratorytestingandrecords•Equipmentcalibrationandrecords•Identificationandcontrolofsamples•Numericalanalyses•ComputerprogramdocumentationandverificationoTransmittalofinformation•Recordcontrolandretention.Auditswillbescheduledtocoincidewithappropriateprojectactivitiesandatothertimesasdeemednecessary.AuditswillbeperformedinaccordancewithwrittenchecklistsandapplicablerequirementsofthisDCQAP.Achecklistshallbedevelopedtoprovideabasisforeachauditidentifyingtheauditscope,activitiestobeaudited,auditpersonnel,anyapplicabledocuments,andtheschedule.Thecheckiistshallbeconsistentwiththeprojectscopeofwork,schedule,andrequirements.Duringanauditanduponitscompletion,theauditorswilldiscussanyfindings,observations,andproposedcorrectiveactionswiththeresponsibleparties:Observationsthatcanberesolvedtothesatisfactionoftheauditorsduringanauditarenotrequiredtcbecitedasitemsrequiringcorrectiieaction.Allfindingsthatare6-1not resolved during the course

of an audit, the auditors shall prepare and submit
an audit report to the appropriate project personnel. This report shall serve
to notify management

of audit results. The report may also be sent to the management

of any affected subcontractor. The report shall be prepared

as soon as possible after the audit and contain,

as appropriate:

• Date(s)

of the audit • Identification

of audit participants • Identification

of activities audited • Audit results • Description

of items requiring corrective action and,

if possible,
the means

of correction • Due date for audit response • Means for audit response

(in writing). The individuals audited shall respond

in writing

to the audit report. The response shall clear[y state the corrective action taken
or planned.

If -all corrective actions have not been completed prior to issuance

of the audit response,

a scheduled date for completion shall be provided. Proposed corrective action must be approved

by the QA officer and the BWXT project manager. Corrective action shall be handled

in accordance
with Chapter 7.0 of this document. After acceptance
and verification

of all corrective actions,

an audit closure report

is issued
by the QA officer. 6-27.0 Nonconformance/Corrective

Action Each nonconformance affecting quality will be documented

by the personnel identifying
the nonconformance.

The nonconformance report may be an audit report, an inspection report,
an internal memorndum,

or other document

as appropriate.
The report must document: • Date of the nonconformance • Identification

of the individual(s) identifying

or originating

the nonconformance report • Description

of the nonconformance • Method(s)

for correcting
the nonconformance (corrective action)

to insure that

it is not repeated • Schedule

for completing corrective action. • Description

of cause
of nonconformance including steps taken
to identify these causes. The responsibility

for tracing the cause
of the nonconformance

rests with the supervisor

or the project leader
of the affected area. Analysis nonconformance

will be addressed

by the laboratory supervisor
and the laboratory
QA administrator.

The predetermined criteria for data acceptability

for laboratory analyses
are defined

in specific standard operating procedures written

to comply with 40 CFR 136 or 40 CFR 261. These criteria are summarized

in Section 5.0 of this DCQAP. Recurring nonconformance

will be evaluated

by project management, laboratory management, and/or the BWXT QA administrator

to determine

its cause and to prevent recurrence

if possible. When such an evaluation

is performed,

the results will be documented.

The BWXT project manager

is authorized

to stop work on the project pending resolution.

7-19.0 Turnaround Time The laboratory analysis turnaround time, for scheduling purposes,

is estimated

to be
2 months. Sample turnaround time for the project

is structured

to accommodate

the additional administrative controls applied

at nuclear facilities

to properly handle hazards associated
with samples that contain

or may contain radioactive materials. Depending

on the location from which samples
are taken and other factors, these. controls may include: • Nondestructive analysis

to determine uranium content and define required shipping paperwork • Special surveys and reporting

of radiological parameters

for the inner and outer containers

to ensure radiological controls are satisfied and that packages
are properly labeled and marked • Preparation

of official radioactive materials transfer documentation

to track the shipment

of materials

to the laboratory
and identify radioactive contents • Similar administrative controls

on radioactive materials received

at the • laboratory

to ensure that the laboratory control program functions properly. 9-1BWXTechnologies,Inc.aMcDermottcompanyNavalNuclearFuelDivisionP.O.Box785Lynchburg,VA24505-0785(804)522-6000May9,2001DavidM.FriedmanU.S.EnvironmentalProtectionAgency,RegionIII1650ArchStreetPhiladelphia,PA19103-2029DearMr.Friedman:Weareprovidingthreecopiesofthebackground,productionprocessandwastewatertreatmentsystemdescriptionsaswellasthegroundwater-monitoringplantosupportthedevelopmentofadelistingpetitionfortheFinalEffluentPonds(FEPs).BWXThasgeneratedthefirstquarterofgroundwatermonitoringdataforboththeFEPsandLandfill1andthesecondquartersamplingwillbeperformedwithinthenexttwoweeks.BWXThasnothadtheopportunitytoreviewindetailthegroundwatermonitoringdatafortheFEPs.PleasegiveJeffreyHowardormeacallat(804)522-5245or(804)522-6677respectively,ifyouhaveanyquestions.Sincerely,kStortonAdvisoryEngineerAttachmentscc:D.Miller,DEQDIOwensDCWardRLCoatsfile
