2.1 INTRODUCTION

This Focused Uranium Tailings Investigation Work Plan was prepared by Harding ESE under Contract Number DACA33-97-C-0023 for the U.S. Army Corps of Engineers, North Atlantic Division, New England District (CENAE) for the performance of work described in the Amendment to Statement of Work - Supplemental Work for Phase II Comprehensive Site Assessment (CSA) at GSA Property Watertown, Massachusetts (the Site), dated August 8, 2001. The work described under this Scope of Work (SOW) falls under the jurisdiction of the Defense Environmental Restoration Program (DERP) Project No. DO1MA001902 and the Massachusetts Contingency Plan (MCP). This document is presented in accordance with U.S. Army Corps of Engineers (USACE) guidance document ER1 110-1-263 (USACE, 1990a). The project will be conducted under the direction of the CENAE, located at 696 Virginia Road, Concord, Massachusetts, 01742-2751. The CENAE architect/engineer (AE) Engineering Manager is Stephen Umbrell. Mr. Umbrell can be contacted at (978) 318-8174, fax no. (978) 318-8614. The CENAE Project Manager is Mr. Randy Godfrey. Mr. Godfrey can be contacted at (978) 318-8717.

The purpose of this focused investigation is to evaluate the potential presence of residual radioactivity in soil that may have been deposited in fill materials used at the Site and the adjoining Metropolitan District Commission (MDC) Property 20 in Watertown, Massachusetts (see Figure 2-1, Site Location Map) in connection with historic usage and activities of the U.S. Army and subsequent tenants of the General Services Administration (GSA) at the GSA Property. The primary objectives of this additional work is to:

Determine whether three previously flagged soil sample locations previously noted by Argonne National Laboratories (ANL) and Morrison-Knudsen Inc. (MK), and identified as possible radiological anomalies during characterization activities contain uranium tailings material.

All work will be conducted in accordance with the requirements of the Massachusetts Department of Environmental Protection (MADEP), the Massachusetts Department of Public Health (MADPH) and the United States Nuclear Regulatory Commission (NRC) in an environmentally acceptable manner conforming to existing federal, state, and local laws and regulations, including the MCP (MCP; 310 CMR 40.0000) as revised through October 29, 1999.

ANL (in 1981) and MK (in 1995) identified anomalous detections of Radium-226 (22 6Ra) in soil at three locations. Both ANL and MK speculated that the 22 6 Ra might be due to the presence of uranium tailings. Massachusetts Institute of Technology (MIT) and American Cyanamid conducted uranium ore research at the nearby Arsenal Site in the late 1940s. However, there is no evidence that tailings were ever brought to or disposed of at the GSA site.

SECTION 2

This work plan outlines the rationale for the proposed additional screening and sampling, the sampling locations, the proposed analytical parameters, and addresses the specifics of the field program procedures. This document also provides the laboratory analytical procedures and methods, as well as describing the data management and quality assurance and quality control (QA/QC) procedures necessary to execute the sampling plan.

2.2 SUMMARY OF PAST WORK

Information presented in this subsection was primarily derived from the Preliminary Assessment (PA) of the Former Watertown Arsenal (ABB-ES, 1993), the Historical Site Assessment (HSA) (Harding ESE, 2000), and the Draft Final CSA (Harding ESE, 2001). The following surveys and investigations related to environmental and/or radiological conditions at the GSA Property were completed between 1967 and 1994:

" In 1967, the Army Materials and Mechanics Research Center (AMMRC) performed a radiological survey of the Northeast Area (now identified as the GSA Property) in preparation for the transfer of the property to the GSA. The survey included alpha and beta-gamma readings of the former depleted uranium (DU) bum area.

" In 1973, AMMRC again surveyed the Northeast Area (GSA Property) after removing isolated pockets of residual radiological contamination. The survey indicated that the property had been remediated to radiological levels then acceptable to the Atomic Energy Commission (AEC), although no published standard existed at the time for radiological contamination in surface soils (see Preliminary Assessment, ABB-ES, 1993). The property was subsequently transferred to the GSA.

" In 1981, the Argonne National Laboratory (ANL) performed a radiological survey of the GSA Property under the Department of Energy's (DOE) Formerly Utilized Sites Remedial Action Program (FUSRAP). The work was performed in July through September 1981 and is documented in a report to the DOE dated October 1983. This survey was performed because documentation contained in AEC and Nuclear Regulatory Commission (NRC) records from previous radiological surveys was insufficient to determine whether previous (AMMRC) decontamination procedures were sufficient to meet more recent NRC standards.

ANL's 1983 report describes the results of uranium fluorometric and gamma spectrometric analyses of soil samples collected from locations 1-S92 and 1-S95 as being indicative of the presence of uranium tailings material. These two bore holes contained what was reported as elevated amounts of 22 6 Ra (decay chain) in concentrations that were not in equilibrium with its parent Uranium-238 (23 8U), indicating the presence of 2 26 Ra with daughters or "tailings" material (i.e., material remaining after the uranium has been chemically separated from ore). The highest 2 26 Ra concentration was found in the first two feet of boring 1-S92, at 13.66 picocuries per gram (pCi/g). Concentrations of 2 2 6Ra in boring 1-S95 were less (5.04 pCi/g) but were considered elevated by ANL. (ANL, 1983)

SECTION 2

" In October 1988, Chem-Nuclear Systems, Inc. (CNSI) to performed a survey of the DU present in the burn area at the northern portion of the GSA Property. CNSI removed, packaged, and disposed of soil and building rubble contaminated with DU. As summarized in the HSA, the work was initiated in October, suspended due to the presence 6f a high water table during winter, and resumed in June 1989.

" In 1990, CNSI performed a CSA of the GSA Property (CNSI, 1990). The CNSI field investigation included surface and subsurface soil sampling, marsh and sediment sampling, and groundwater sampling. Targeted analytes included volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), total recoverable petroleum hydrocarbons (TRPH), Resource Conservation and Recovery Act (RCRA) Metals, and uranium. The field investigation included thirty-one soil borings to depths ranging from 10 to 51 feet below ground surface (bgs), eleven groundwater monitoring wells, six surface water and sediment samples, characterization of site geology and hydrogeology, hydraulic conductivity testing, a wellhead elevation survey, and depth to groundwater measurements. A characterization of risk of harm to human health, public safety and welfare, and the environment was performed at the conclusion of the investigation. The chemical laboratory data summary tables from the CNSI CSA have been reproduced in Appendix A of the original ABB-ES project CDAP (ABB-ES, 1994), to which this document is an addendum.

" CNSI concluded that outside of the burn pit, total uranium concentrations in soils, sediments, surface water, and ground water were below regulatory limits established by the NRC with one exception. A small, isolated area previously identified in 1989 by CNSI contained uranium above the then established clean-up levels.

" An interim removal measure to excavate radiologically contaminated soil was subsequently conducted at the GSA Property. The objective of the interim measure was to define, remove, and dispose of radiologically contaminated and/or mixed waste materials in soil and groundwater near the DU burn area. A 1,000-gallon heating oil underground storage tank (UST) was also excavated and removed from the site.

" Beginning in January 1993, Morrison Knudsen Corporation (MK) performed remediation and site characterization activities at the GSA Property (Harding ESE, 2000). In a July 1994 Work Plan For Additional GSA Site Characterization, MK identified additional efforts which would be required to complete the radiological characterization of the site. These efforts included evaluation of Property 20, the radiological characterization of Building 653, sediment sampling in Manhole #147, determining the extent of radiological contamination remaining near the burn area, estimating the amount of remaining DU chips at the site, radiological surveys of Areas II and V (the clinker area and Property 20), and evaluation of whether former DU stabilization activities led to windborne dissemination of radiological contamination. The effort to complete the characterization of the burn area included the sampling of wells B-25 and B-31, installed in the vicinity of the burn area in October 1993.

SECTION 2

Two addenda were added to MK's document, in January of 1996, and in November of 1997. The 1996 addendum addressed additional in-situ gamma spectroscopy which was completed along the site boundary and in the site interior which had previously been surveyed for DU chips and/or non-specific exposure rate. The 1997 addendum provides calculations detailing the background uranium concentration on the site, the total activity of the uranium on the site, and estimates of the potential for groundwater contamination by uranium at the site. Results are summarized in the Historical Site Assessment (Harding ESE, 2000).

MK concluded the following:

(1) There were no significant areas of excess gamma radiation.

(2) The fine particle size fraction of soil from the Burn Pit and some of its surroundings was contaminated with DU.

(3) An area of approximately 9,700 ft2 was contaminated with DU chips to an estimated depth of 1 foot.

(4) Localized DU and potential uranium ore tailings in soil existed in Property 20.

(5) All buildings on the GSA site met release criteria for future unrestricted use.

(6) The boundary areas and the area along the riverbank across Greenough Boulevard (the downwind, down gradient boundary) were not impacted by Site activities involving radioactive materials.

MK's 1996 report speculated that tailings material might be present at location FS-01, based on their interpretation of the 2 26 Ra and thorium-234 data for soil collected from this location (MK, 1996.

" A detailed preliminary assessment (PA) of the GSA Property was completed by Harding ESE (then ABB Environmental Services) in 1993 (ABB-ES, 1993). The PA focused on historical property usage and did not include the collection or analysis of environmental samples.

" In October and November 1994, Harding ESE conducted a Phase II CSA. The CSA consisted of soil borings and soil sampling, groundwater monitoring well installations and sampling, water level measurements, and surface water and sediment sampling. In 1996, additional test trenching and drum excavations were performed as part of the CSA. Additional soil, sediment, and surface water sampling was conducted in 1994-1995, 1998 and 2000. CSA investigation activities did not include radiological investigation.

2.3 SITE DESCRIPTION

The GSA Property was acquired by the U.S. Army from the Commonwealth of Massachusetts in 1920 as part of the expansion of the Army Arsenal located on the opposite (south) side of Arsenal Street. The 12

acres of land comprising the GSA Property were vacant prior to Army ownership. The Army used the Site for landfilling of foundry materials and debris. By 1948, this landfilling had nearly reached the property boundary. Through MDC permits covering the period 1948 to 1951, the Army was allowed to extend their landfilling activities and place fill materials on Property 20. The Army used the property for storage of machine shop jigs and fixtures during the 1950s and subsequently for the storage of vehicles, miscellaneous military equipment, and various salvage and scrap property (CNSI, 1990). Various construction and/or demolition rubble were reportedly disposed of at the GSA Property during this time.

MIT and American Cyanamid conducted uranium ore testing at the Arsenal from 1946 through 1953. A modified ion exchange technique for production of triuranium octaoxide (U30 8), which employed a fluidized bed system, was developed at the Site. The waste products from this testing likely consisted of ore tailings containing uranium daughter products. No historical indication of tailings disposal at the GSA property or Property 20 has been discovered.

In about 1955, a fenced area in the northern portion of the GSA Property was designated for the stabilization of DU metal turnings and DU waste generated from machining operations at the Arsenal. The stabilization process consisted of placing DU scrap in large steel dumpsters and igniting the pyrophoric DU chips and shavings to reduce the volume of the material. This process converted the pyrophoric DU metal into uranium oxide prior to off-site shipment and disposal. The stabilization took place on a concrete pad within a fenced enclosure, and the "burn pit" did not actually become a pit until the excavation contractor began removing contaminated material in 1990. The former burn area now consists of an excavated pit approximately 25 to 30 feet in diameter and 3 to 4 feet deep (CNSI, 1990).

GSA received the property from the Army in 1967 and subsequently used it for storage and auction of excess property. The Federal Bureau of Investigation (FBI), the Drug Enforcement Agency, and the Internal Revenue Service also used the property for storage. The GSA also leased portions of the property to tenants including automobile dealers and a television production company.

During the 1993 PA (ABB-ES, 1993), former usage of an adjoining property by the Army was identified. This adjoining property is referred to as Property 20 and covers approximately one acre of land. Property 20 is located at the northeast tip of the GSA Property and belongs to the Commonwealth of Massachusetts as administered through the MDC. By 1948, the placement of refuse and debris materials by the Army on the GSA Property had nearly reached the property boundary. Through MDC permits covering the period 1948 to 1951, the Army was allowed to extend their landfilling activities and place fill materials on Property 20.

The site is mostly unpaved and contains delineated wetland areas. Sawins Pond Brook runs along the southern property boundary and connects Sawins Pond and Williams Pond with the Charles River.

A chain link fence surrounds much of the property. There are currently five separate numbered building structures at the GSA Property. The buildings were constructed between World War II and 1952 and are numbered from 234 through 237, and 653. None of the buildings are currently used.

SECTION 2

The site was first listed by MADEP as a disposal site (Release Tracking Number 3-2722) on January 15, 1990 as a Location to be Investigated (LTBI). The site was subsequently classified as a Priority Site in June 1992. MADEP supervisory personnel cited five principal site conditions that led to the priority classification: residual radiological contamination, the potential presehce of mixed waste at the site (soil previously excavated from the burn area reportedly failed TCLP for lead), proximity to the Charles River, proximity to Sawins Pond Brook, and the high water table. The site is currently listed as a Tier IA site under the MCP.

Due to the presence of on-site wetland resource areas (including the adjoining Property 20), the majority of the work performed to date has been conducted in accordance with an Order of Conditions and Permit for Work, MADEP File #321-39, issued to the USACE on November 1992 pursuant to the requirements of the Wetlands Protection Act, M.G.L. Chapter 131, Section 40 and the Town of Watertown's Wetlands Ordinance. The aforementioned Order of Conditions and Permit for Work were amended in August 1994 and remain in effect following an extension in August 2000.

2.4 SCOPE OF WORK FOR FOCUSED URANIUM TAILINGS INVESTIGATION

The primary objective of this investigation is to determine whether historic anomalous screening and sample data from three locations at the northern and western edges of the Site are reproducible and due to the possible presence of uranium tailings at the Site.

As noted in Section 2.2, previous investigations conducted by ANL in 1983 and MK in 1996 reported three locations at the western edge of the GSA Site and in Property 20 with anomalous isotopic ratios that may be indicative of uranium tailings material. These locations include the ANL locations 1-S92 and 1S95 as well as the MK location FS-01 (locations shown on Figure 2-2, attached). However, it is believed that the conclusion that tailings may be present at the GSA Site may have been based on an incorrect interpretation of the available data.

In the MK surveys, a gamma spectral analysis was employed to measure the amount of residual radioactivity in soil and in water. The thorium-234 (2 3 4Th) gamma signal served as an index, or surrogate for 2 3 8U, which does not have a suitable gamma signal at concentrations encountered at the GSA site to be measured directly. This alone is appropriate and credible and does not diminish the value of the data collected for determining the concentration of 2 3 8U present in soil. However, the data collected was also used to provide input to an algorithm used to determine whether the radionuclide profile was indicative of DU (essentially pure elemental uranium stripped of uranium 235 (2 3 5U)

nuclides) or alternatively, indicated the presence of uranium in its natural isotopic ratios in some equilibrium association with its progeny. At low concentrations of 23 8 U (i.e., concentrations near background), counting statistics, the natural variability in the background concentrations of2 35 U, 2 38 U, 2 34 Th, and 2 26 Ra nuclides, and the variability in the elemental and isotopic purity of DU make the

distinction between DU and other radionuclide profiles (such as those characteristic of uranium tailings) a dubious task. In the case of the location reported by MK as potentially having uranium tailings materials in soil, a peak stripping algorithm was used to attribute portions of a common photo-peak shared by both 2 2 6Ra and 2 35 U. Use of this algorithm assigned activity to 2 26 Ra rather than 22 6Ra being discretely measured.

SECTION 2

2.4.1 Soil Screening Using Gross Gamma Measurements and Soil Sample Collection

Harding ESE will attempt to reacquire the three MK and ANL locations where anomalous 22 6 Ra concentrations were reported using location data obtained from histo'rical Site figures and a GPS unit. Harding ESE will then establish a 20' x 20' survey area grid surrounding each of the reacquired locations. This survey area is large enough to account for potential discrepancies in pinpointing locations that were sampled up to 20 years ago, and provides an efficient means of evaluating a larger representative area. A series of 10 to 15 timed direct static measurements will be made within the survey grid to establish the mean and the 2-sigma (95 percent) upper confidence limit (UCL) about the mean (UCL 9 5) within the area. A scan investigation level corresponding to 1.5 times the (UCL 95 ) will be established.

Next, a gross gamma scan of the surface of the soil within the 20' x 20'survey area will be performed using a 1.5" x 1.5" Sodium Iodide (NaI) detector. Scans will be performed to locate the highest gamma count rate readings within the survey area. Grid locations at which gamma count rate measurements exceed the investigation level (1.5 times the UCL9 5 for the area) will be flagged for further investigation.

Locations within the survey area flagged as having gamma count rates in excess of the investigation level will be further surveyed by collecting 1 minute, static (time integrated) count rate measurements. Soil samples will be collected from the three locations with the highest 1 minute, static (time integrated) count rate measurement results. In addition, soil samples will be collected from the 0 to 1 foot interval bgs and submitted for laboratory analysis by both alpha and gamma spectrometry. If gross gamma scanning over the survey area produces no measurements in excess of the investigation level, soil samples will be collected from the center of the 20' x 20' grid (the reacquired, historical sample location based on the GPS unit coordinates) and at the location with the highest direct static count rate measurement among those used to establish the investigation level. Thus, no more than three and no fewer than two physical soil samples will be collected from each of the three study areas.

Section 5.0 of this CDAP presents the details and methods proposed for the field sampling program.

2.5 PROJECT SCHEDULE

Radiological screening and sampling will proceed within six weeks of approval of this work plan, contingent on the availability of CENAE and MADEP personnel who will be overseeing the sampling event. Also as discussed in Section 5 of the Harding ESE March 2002 CDAP Addendum (Harding ESE, 2002), two monitoring wells will be resampled for lead in groundwater near the burn pit (a radiologically controlled area). This groundwater sampling will be conducted at the same time asthis tailings sampling program while a health physicist will be present at the site.

Analytical results from the tailings investigation will be available 30 days after laboratory submittal of the soil samples. A technical memorandum documenting the results of the sampling and recommending future courses of action (if any) will be submitted to CENAE within 30 days after receipt of laboratory results.

3. RADIOLOGICAL DATA QUALITY OBJECTIVES

The scope of this investigation is focused on three locations at whicfi the results of previous sampling conducted by others were interpreted to indicate the potential presence of uranium tailings.

At these three locations, a gross gamma scan and soil sampling will be conducted in an effort to determine the isotopes present at these locations and further evaluate the possible presence of uranium tailings. Soil samples at each location will be analyzed by gamma spectroscopy for uranium and its daughters, thorium and its daughters, and radium-226 and -228. In addition, alpha spectroscopy will be used to determine the activity of uranium-234, -235, and -238, and thorium-228, -230, and -232.

Based on the alpha and gamma spectroscopy data, isotopic activity ratios between uranium, thorium, and radium isotopes will be calculated. If the isotopic ratios present in the soil samples indicate the presence of thorium and radium in concentrations significantly different than those that might be expected with depleted or natural uranium and are indicative of ratios supporting the presence of tailings, then recommendations will be provided to CENAE regarding the need for additional sampling and surveys to establish the magnitude and extent of the tailings.

5. FIELD PROGRAM PROCEDURES AND REQUIREMENTS

The following is a summary of the additional field activities as specified in the SOW (CENAE, 2001) for the GSA Property:

"* Radiological Screening "* Soil Sampling

Field activities conducted by Harding ESE will be performed in accordance with the CDAP and the Site Safety and Health Plan (SSHP) (ABB-ES, 1994, 1995, 1997; HLA, 2000; Harding ESE, 2002). Refer to the original project CDAP for general field program procedures and requirements. Any updates and information specific to this additional field effort are presented below.

During this field program, Harding ESE will conduct field screening for the potential presence of uranium tailings material in soil and obtain representative soil samples for laboratory analysis. The analytical results will be used for the following purposes:

Biased screening data will be collected at previous sample locations to ascertain whether the presence of uranium tailings is possible. Results will be used to make a qualitative decision as to whether tailings are present at those locations and by extension determine whether it is credible to consider that uranium tailings may have been disposed on the GSA Site (including the affected portion of Property 20).

The proposed investigation areas at the site are shown on Figure 2-2. Rationale for individual sample locations are shown in Table 5-1. Details of the laboratory analytical program are presented in Section 7.0.

The following subsections summarize the field activities. The procedures described reflect Harding ESE's standard procedures and are consistent with CENAE guidance.

5.1 DEFINITIONS

Refer to the original project CDAP for definitions of terms that may be applicable to the proposed sampling and analysis program. Definitions listed in the CDAP are from Appendices D and G of the USACE Guidance Document ER 1110-1-263 (USACE, 1990a).

5.2 EQUIPMENT AND SUPPLIES

The equipment and supplies required to support field activities are shown in Tables 5-2 and 5-3. Table 5-2 presents a summary of the non-expendable equipment necessary for soil sampling, nonradiological health and safety monitoring, equipment and personal decontamination, and general field operations. Table 5-3 summarizes the expendable supplies required for the field investigation.

5-1

SECTION 5

Equipment handling, maintenance, and calibration procedures for environmental monitoring instruments are summarized in Section 5.2 of the original project CDAP.

All the equipment and instruments used in the field screening operations shall be maintained and calibrated to manufacturer's specifications to insure that the required traceability, sensitivity and precision of the instruments/equipment are maintained. A calibration/maintenance file shall be kept on all equipment used in the field screening analysis which should include: name of the equipment, equipment identification, manufacturer, calibration frequency, date of calibration and date of next calibration due, manufacturer's operating instructions, manufacturer's calibration and maintenance instructions.

5.3 SAMPLE LOCATIONS AND RATIONALE

Sample locations and sampling parameters were selected based on the information presented in the SOW (CENAE, 2001), review of existing site-specific documents, including ANL's 1981 report, MK's 1996 report, and the HSA (Harding ESE, 2000), data collected during previous site walkovers, and comments received from the MADEP and CENAE. The field program sampling locations and rationale are presented in Table 5-1 and Figures 2-2, 2-4 and 2-5, and the summary of the contract laboratory analyses is presented in Table 5-4.

5.3.1.1 Gross Gamma Soil Screening and Sample Collection

Previous investigations conducted by Argonne National Laboratories (ANL) in 1983 and MorrisonKnudsen (MK) in 1996 have identified three locations at the northern edge of the GSA Site and in Property 20 with anomalous uranium series isotopic ratios which may be indicative of uranium tailings material. These locations include the ANL locations 1-S92 and 1-S95 as well as the MK location FS-01 (locations shown on Figures 2-2, 2-3 and 2-4). Elevated concentrations of Radium-226, possibly indicative of tailings material, were reported at these locations.

Harding ESE will attempt reacquire the three locations of elevated Ra-226 concentrations using location data obtained from historical Site figures and a GPS unit, capable of sub-meter accuracy. A 20-foot by 20-foot grid will be cleared of small brush and seedlings to a height of six inches or less in order to permit the area to be scanned. Large trees will not be removed. All cleared material will be placed near the sample location, and not removed from the Site. If standing water is encountered, the area to be scanned will be relocated to the nearest area that is dry enough to permit radiological scanning to take place.

A series of 10 to 15 timed direct static measurements will be made within the survey grid to establish the mean and the 2-sigma (95 percent) upper confidence limit (UCL) about the mean (UCL 9 5 ) within the area. A scan investigation level corresponding to 1.5 times the (UCL95) will be established. The grid locations of the direct static measurements are indicated on Figures 2-3 and 2-4.

Harding ESE will then scan the 20-foot by 20-foot grid surrounding each of the reacquired locations in order to account for potential discrepancies in pinpointing locations which have been sampled up to 20

years ago. Scanning will then be conducted using a 1.5 inch by 1.5 inch Sodium Iodide (NaI) detector. The scan personnel will move at a slow, walking pace, and will swing the instrument in a two-foot arc to

either side of the path. Figure 5-1 illustrates the path of sampling progress.

Scan results from each study area will be compared to the area average gamma count rate. Discrete locations at which a scan result exceeds the investigation level (1.5 times the UCL9 5 of the mean for the

area) will be flagged for additional measurement. Flagged locations will be assayed in-situ using a timed

static count measurement and recorded. The three flagged locations having the highest timed static count

measurement results will be targeted for soil sample collection. Soil samples will be collected and

submitted for laboratory analysis by gamma and alpha spectrometry. If no scan results in excess of 1.5

times the area mean are detected in a study area, soil samples will be collected from the original sample

location (as indicated by the GPS) and at the grid location with the highest in-situ direct static

measurement survey result. At a minimum, two soil samples will be collected from each study area for laboratory analysis.

5.4 SAMPLING AND FIELD INVESTIGATION PROCEDURES

The sampling program to support the Focused Uranium Tailings Investigation is designed to provide

sufficient data to determine whether uranium tailings are present in surface soils in significant

concentration and quantity within the suspect survey areas. Development of the proposed sampling

procedures considered site-specific factors, the evaluation of previous sampling results, and the scope and objectives of the project.

The following subsections discuss field investigation techniques, sampling procedures, and data

management requirements that will be implemented during the additional work supporting the Focused

Uranium Tailings Investigation. Field investigation activities will be conducted in accordance with

requirements specified in the SOW (CENAE, 2001) and this sampling plan unless individual site

requirements dictate modifications. Any program modifications will be communicated to the CENAE

Engineering Manager through the Harding ESE project manager.

5.4.1 Decontamination

Decontamination activities will be conducted in the study area in which the equipment was used.

Decontamination will consist of a deionized water rinse to remove all soil particles from the sampling

equipment. If visible particles remain, a deionized water/liquinox mixture will be used to remove

residual materials, and followed by a deionized water rinse. Equipment such as shovels, spoons, spatulas,

sieves, and bowls will be decontaminated between each sample in order to prevent the possibility of

cross-contamination of samples. Following decontamination activities, decontamination liquids will be

discharged to the ground in the study area. Field equipment blank samples will not be collected; instead, sample equipment will be scanned using a pancake meter as necessary to evaluate whether further decontamination is required.

SECTION 5

5.4.2 Soil Sampling

A clean stainless steel shovel, spoon, or hand auger will be used for soil sample collection. Soil will be collected from the top foot of soil bgs. Soil will be passed through' a US Standard Number 10 sieve (nominal sieve opening of 2 millimeters) and into a stainless steel bowl. This step will remove the larger particle size fraction (stones, roots, debris) and provide a more homogeneous sample. Because uranium ore would have been ground into a fine material prior to extraction, potential tailings would be expected to remain in the fine soil fraction. The large sample fraction will be returned to the sample location. The sieved soil will be collected in a stainless steel bowl and homogenized prior to transfer to the sample container. Observations related to sample characteristics (e.g., color, grain size, odor, etc.), will be recorded on a sampling form. Excess soil will be returned to each sample location.

For each sample, the sieved soil will be transferred to a 500 milliliter Marinelli Jar. The soil will be packed into the container to approximate the in-situ bulk density; the volume of soil necessary for the proper sample geometry will be specified by the laboratory. The Marinelli Jar will be capped and the cap sealed by wrapping four turns of electrical tape around the circumference of the cap seam.

The Marinelli Jars will be submitted to the contract laboratory for analysis by gamma spectroscopy. The jars will remain sealed until the gamma analysis has been completed. The laboratory will then break the seal, and remove a quantity of soil for determination of soil moisture content. The sample will be dried and pulverized by the laboratory, and then analyzed by alpha spectroscopy.

These steps will help to provide a uniform and consistent sample for each analysis, and reduce uncertainty that can be introduced by soil heterogeneity.

A summary of specific containers, sample volume, preservation, and holding time requirements is provided, by analysis, in Table 5-5.

SECTION 7

7. LABORATORY ANALYTICAL PROCEDURES

Off-site laboratory analytical analysis of samples obtained during the Focused Uranium Tailings Investigation will be conducted by a USACE-MRD validated laboratory. Harding ESE will subcontract to Severn Trent Laboratories (STL, formerly AEN), which is USACE-MRD validated for the parameters that are part of this investigation. Analyses for all MRD-validated parameters will be performed by STL's St. Louis, MO laboratory.

All radiological analyses will be performed according to methods designated in Table 7-1. Table 7-2 summarizes the samples to be handled by STL. Data quality guidelines are designated at USEPA Level III for all contract laboratory analyses. USEPA data quality guidelines are discussed in the original project CDAP (ABB-ES, 1994), and defined in Section 5.0. Specific data quality objectives will be outlined within this section.

7.1 ANALYTICAL METHODS

The analytical methods for each of the target groups of compounds are discussed below. A detailed summary of the analytical methods is included in Table 7-1.

7.1.1 Gamma Spectroscopy

Soil samples will be analyzed by gamma spectroscopy for isotopes of the uranium series, including uranium and daughters of uranium, the thorium series (thorium and daughters of thorium), Radium-226, and Radium-228. The required detection level (2-sigma) will be 0.5 pCi/g per significant gamma emitting isotope.

The field-prepared Marinelli Jars will be allowed to stand a minimum of 10 days to allow in-growth prior to analysis.

7.1.2 Alpha Spectroscopy

Soil samples collected during this program will be analyzed for Uranium-234, Uranium-235, Uranium238, Thorium-228, Thorium-230, and Thorium-232 by alpha spectroscopy. The required detection level (2 sigma) will be 0.1 pCi/g for each isotope.

Alpha spectroscopy analysis of each soil sample will occur after the samples have been subjected to gamma spectroscopy analysis. The Marinelli Jars will be opened by the laboratory and a quantity of soil removed for determination of soil moisture content. The soil will be dried, pulverized, and then analyzed by alpha spectroscopy.

SECTION 7

7.2 QA CORRECTIVE ACTION

The analytical laboratory will provide Harding ESE with data generated only when the analytical system was determined to be in control. Corrective action for out-of-contr&l situations will be performed in accordance with the following procedures:

Out-of-control situations in the laboratory are investigated by the analyst and the QAM to determine the cause and to decide on the appropriate corrective action. Out-of-control situations may involve either a single data point or trend established by several data points. The details of the situation and the corrective action taken are fully documented in a corrective action report submitted to the Harding ESE LSC. Affected field sample data are evaluated and reanalyzed as necessary. When a method is determined to be out-of-control, the analysis of field samples is suspended. Corrective action must be documented and the method must be demonstrated to be in control before analysis of field samples may resume. Analytical control is demonstrated by acceptable analysis of QC samples.

7.3 DATA MANAGEMENT

Harding ESE will reduce and review data collected during the field investigation and report the findings in a standard format.

7.3.1 Data Reduction

Data reduction at the laboratory is the process of converting measurement system outputs to an expression of the parameter that is consistent with the comparability objective. Calculations made during data reduction are described in the referenced analytical methods and in the participating laboratories' QA Program Documents.

Upon receipt, each analytical data package is turned over to the Harding ESE data entry staff for reduction to standard data tabulations. Reduction may occur in one of three ways:

"* the data are manually entered into data table templates; "* the data are downloaded directly from the laboratory computer; or "* the data are loaded from magnetic media supplied with the data package by the laboratory.

Completed data tabulations are provided to the data review staff. As described below, one additional data tabulation will be prepared. The original data, tabulations, and magnetic media will be stored in a secure and retrievable fashion.

7.3.2 Data Review and Validation

All analytical data generated during the field investigation will be reviewed by Harding ESE technical staff. The analytical laboratory will review data to ensure QC criteria were met. If criteria are not met, the sample will be reanalyzed within specified holding times.

Harding ESE, Inc.

SECTION 7

7.3.3 Data Reporting

Two presentations of the analytical data will be prepared. The data tables will represent:

"* The raw data as received from the laboratory, tabulated by media and analytical fraction. "* The annotated data resulting from the review process, tabulated in a similar format.

Results will be reported as actual measurement results, whether positive or negative with the associated uncertainty for all radionuclide analyses. Results will not be reported as "less than" or "not detected". The number of significant figures for results shall reflect the precision of the analytical technique.

7.3.4 Data Deliverables

Deliverables associated with analytical results will include a complete data package satisfying the requirements of the project, CENAE guidance document ER- 1110-1-263 (1990a).

8. DELIVERABLES

Reports or documents described in this section are required submitials in accordance with the SOW (CENAE, 2001) for this project. These deliverables cover the period of project performance from commencement of field activities through submittal of a memorandum documenting the results of this focused tailings investigation. Required deliverables identified as Chemical Data Quality Management (CDQM) documents specifically address data quality issues. Table 8-1 provides a summary of the CDQM documents to be produced, including a description of the document, frequency of submittal, and the approximate submittal schedule.

The results of the sample analysis described in this document will initially be incorporated into a technical memorandum. If this investigation concludes that no tailings are present in surface soil within the survey areas, and this technical memorandum documenting this conclusion will be a sufficient final deliverable. Should the results be inconclusive or should there be evidence of tailings, a more rigorous MARSSIM-based investigation will likely be necessary, and the technical memorandum will provide recommendations for subsequent courses of action.

Project Experience Confidential Utility Client, Massachusetts. As Principal, has been involved in developing strategic plans to gain acceptable closure of several manufactured gas plant (MGP) sites in New England. Provides insight to the assessing potential environmental liability as well as definition of financial liability associated with site conditions. Each of the former MGP sites involves site conditions which require thorough understanding of MGP processes, identification of MGP residuals, assessment of human health and ecological potential risk, and development of effective and appropriate clean-up objectives for agency approval. Provides continuity and consistency in technical approach for the sensitive environmental issues of these projects to avoid establishing inappropriate precedence and to promote standardization of risk assessment and innovative technologies.

Confidential Utility Client, New Jersey. Principal management on multiple former Manufactured Gas Plant Sites. Managed the development of a standardize ecological risk evaluation approach for multiple site use. The generic approach captures important ecological sensitivity issues surrounding an MGP location in a decision document to derive conceptual assessment of liability and remedial alternatives. This approach can be generally accomplished with existing information although site-specific characterizations can be imported into the conceptual ecological risk model. Other projects for this client include site investigation, construction management, design and implementation of remedial actions, coal tar bioremediation studies, and remedial action feasibility studies.


Robert Nicoloro - Page 2

Former Manufactured Gas Plant, Confidential Utility Client, New Hampshire. Provided leadership and principal management in the development of a strategic discussion document to demonstrate to its client the options and prudent pathway for the project to arrive at site closure certification in the shortest amount of time and the most economical means. This decision document is extremely important as a management tool for the client to make smart business decisions relative to this site. The application of this site includes both risk assessment and remedial approaches which can be used on other client sites. The approach and decision document have been presented to the New Hampshire Department of Environmental Services with very favorable review. Actions to close the site will continue following this strategic model.

Former Textile and Manufacturing Mill, Confidential Client, Rhode Island. Senior Project Manager and Principal on a large mill decommissioning project involving a 1902 former textile mill and a 40-year-old rubber equipment manufacturing operations. The manufacturing company made the difficult decision to close the plant. Assisted by providing logistical planning and decommissioning environmental assessment for the property and buildings to be closed and placed on the real estate market. During indoor assessment activities, it was determined that dust which had accumulated for many years contained heavy metals at significant concentration levels. Developed a cleanup strategy based on potential occupational exposures. Developed sampling and analysis plan, managed the implementation of that plan as well as the development of action levels. A decontamination plan was prepared and contract specifications went out for bid. Managed the selection of the contractor, oversight of the decontamination work, and the successful clearance of the building. The mill building has been transferred to a new owner for the maximum market price, well exceeding the cost of decontamination and the expectations of his client.

Project Experience While With Roux Associates, Methuen, Massachusetts, 1995-1997 Mr. Nicoloro began a new venture for Roux Associates by opening a start-up office in Massachusetts. Starting as a one-person office, Mr. Nicoloro began building client relationships backlog of work. After two years, the office had 12 environmental professionals and substantial client base to support the office as a profit center. During this. time Mr. Nicoloro conducted work at two urban sites impacted from manufactured gas plant (MGP) residues. Each site required initial investigation and the development of risk-based cleanup objectives consistent with the Massachusetts Contingency Plan (MCP). Developed a comprehensive response action plan to include remedial action alternatives to stabilize MGP residuals onsite through a contractor stabilization process. Portions of one of the sites were also identified for in situ bioremediation.

Prepared justification and technical arguments for the a no-further-action alternative regarding manufactured gas plant residuals and coal dusts residuals. This argument was presented in the context of defending a position of no further action based on a coal ash exemption and local background conditions. This argument was upheld by outside legal counsel advising the client. The basis for limited investigation and hot spot removal of oil contaminated soils were the only remedial actions necessary under the MCP to be taken by the client.

Managed the technical review of site investigation information, background process information and clean-up strategies developed for 17 manufactured gas plants. These sites ranged for 4- to 30-acre sites. Each was different in configuration and plant layout. Some facilities were vintage MGP locations established in the mid 1800s, while others were later 1900s construction. There were significant issues to resolve concerning gas holder and relief holders residuals, tar ponds and pits, oxide waste residual identification, amenable cyanide risks, site environmental setting and human health risks, and potential redevelopment options following a Brownfields process. Prepared summary documents as part of



litigation support. These documents included the development of realistic and realistic worst-case remediation and development scenarios. Each scenarios summary included an engineering cost estimate for potential remedial action alternatives. In many cases, Mr. Nicoloro developed and justified a position of no further action, limited investigation and monitoring, or hot-spot removal and site closure. Through in-depth knowledge of the MGP processes and direct experience in site'investigation and remedial action at MGP sites, Mr. Nicoloro successfully defended the technical merits of the arguments made.

Managed the decommissioning, demolition and site cleanup remedial actions at an 11-acre former rubber manufacturing mill complex. The complex included 5 large mill production buildings each 5 stories on an 80,000-square-foot building footprint. As the buildings were being demolished and the foundations were removed, oils were discovered on soil and groundwater onsite. Developed a cleanup plan to remove the oil contaminated soils and keep the building demolition activities on or close to schedule. In addition, coal-tar and coal ash residuals, possibly from a near by former manufactured gas plant (MGP) were discovered onsite used as fill and building material during the original circa late 1800s construction. A cleanup plan was developed for this material and include asphalt batching for the portion of material identified as building debris and no further action alternative for material used as fill. An argument for local conditions background and coal ash exemption was used to justify the no-action alternative. In addition, a risk-based cleanup object was established for the site which excluded much of the MGP residual from further action.

Project Experience While With ENSR Consulting and Engineering, Action, Massachusetts, 19871995 Managed numerous large projects under CERCLA, RCRA Corrective Action, state programs, voluntary client initiatives, large-scale due diligence efforts, and litigation support for clients across the country. Experience in site investigation and remedial actions involving the oversight of USEPA in five USEPA Regions to include Regions I, II, III, V, and VI.

Conducted site investigation and remedial actions at major electric and gas utility sites to include the Con Edison Astir New York RCRA Corrective Action Site. This site is identified as the largest manufactured gas plant in the world in the 1930s. The site operations were the culmination of years of MGP technology and state-of-the-art construction product purification. In addition, the site was Con Edition's largest fossil fuel generating station with six large boilers, 17 gas turbines, and large transformer substations. Numerous locations of PCB contamination, oil contamination were situated among years of coal tar deposits, purifier waste, and coal/coal ash residuals. Developed a site investigation strategy which focused on a risk-based approach to site issues. The approach was approved by the New York State Department of Environmental Conservation. The technical strategy in the approach focused on removing metals from risk potential, the isolation of the large coal-tar ponds which had been backfilled over, obtaining a reasonable risked-based PCB cleanup level in excess of 25 ppm, and hot spot removal of both PCBs and fuel oils. Based on a strong argument for non-residential future use, many issues such as cyanide residuals and poly aromatic hydrocarbons were removed from consideration through a defensible risk screening methodology. In addition, developed an argument that sediments and surface water involving the East River were not warranted based on preliminary site investigation data.

As Principal-In-Charge, managed a large RCRA Corrective Action project involving an 80-year-old chemical plant adjacent to a swift moving river within USEPA Region V jurisdiction and oversight. Activities included the development of equitable consent order language, the preparation of a description of current conditions which eliminated 14 solid waste management units from consideration, development and implementation of a comprehensive RFI to include very demanding USEPA Region V



sampling and data management protocols, and the risk evaluation of volatile organic compounds, poly aromatic hydrocarbons, and metals. The site also used coal as a fuels source. Coal ash and coal leachate were a concern to the agency. A specialized sampling protocol was developed and approved by USEPA for the determination of coal and coal ash residuals in river sediments. The were several landfill depositions on site adjacent tot he river bank. Each fill location was investigated and characterized. Coal ash, filter cake and phthalate compounds were the primary contaminant. Metals and cyanide residuals were also issues at these landfills.

Project Experience While With United States Army, Fort Devens, Massachusetts, 1981-1987 Environmental Coordinator - Civilian. Managed the environmental affairs of the military installation to include the 9200-acre facility and firing ranges, 2300-acre training annex, 3200-acre excess property, and 73 New England U.S. Army Reserve Center locations. Prepared installation environmental impact statements and assessments, off-site training environmental document, the installation's environmental master plan, and worked closely with the U.S. Army Corps of Engineers.

Responsible for the second largest environmental budget in forces command for the second smallest Army installation within Forces Command. Gained public and agency approval for the first federal facility RCRA Part B Permit in New England. Member of the DOD environmental compliance auditing committee and was provided the initial $43MM budget for CERCLA actions from the Defense Environmental Restoration Program approved by Congress.

Manufactured Gas Plant Experience Provides in-depth practical experience in the assessment, risk evaluation, and remediation of manufactured gas plant (MGP) sites. Provided senior project management and principal support on large-scale site investigations focused on characterization of MGP residuals in a variety of environmental media. Conducted work at several complex MGP sites, the largest being the Consolidated Edison (Con Edison) facility in Astir, New York. From 1900 to 1950s this 360-acre site was a manufactured gas plan servicing the boroughs of New York City. By the 1930s, this plant was the largest MGP facility in the world. Operations also included the use of byproducts for manufacturing of explosives during World War I1.

Site characterization identified residuals of coal tar, metals, complexed cyanide, PCBs, benzene, and carcinogenic polyaromatic hydrocarbons in soils, groundwater, river sediments, surface water, and within the sewer system of the facility. Successful in negotiating realistic cleanup levels for PCBs, benzene, and chlorinated compounds with the New York Department of Environmental Conservation. Metals, PAHs, and other semi-volatile compounds were negotiated out of the remedial activities through risk assessment. Coal tar residuals were allowed to remain onsite with no further action. River and sediment studies were avoided due to favorable ecological risk assessment results. Activities were conducted under a RCRA Corrective Action Permit.

In addition to the Con Edison site, Mr. Nicoloro has experience with Colonial Gas Co., Essex County Gas Co., and Public Service Electric and Gas. Also conducted in-depth evaluation of site characterization data, and the feasibility of proposed remedial actions at 17 MGP facilities. Managed and has been directly involved in MGP project work involving the following activities:

"* Site characterization (coal tars, cyanides, metals, benzene, DNAPL, LNAPL, PCBs);

"* Historic land use and research into MGP operations, facilities and construction;



" Risk assessment (coal tar migration, complexed cyanides, surface water, sediments, and soil exposure pathways, carcinogenic PAHs, demonstrations of no significant risk);

" Delineation of source areas (tar ponds and storage tanks, gas and relief holder residue, purifier waste, oxidizer waste, engine house waste, retort residuals, and coal leachbate);

Remedial Design/Remedial Action (capping, steam injection solidification, wetlands mitigation/restoration, sewer relining, free-product recovery, oil/water separator and permitted discharge, demonstration of technical impracticability);

" Liability assessments (source area identification, nature and extent of contamination, off-site assessments, groundwater modeling, engineering estimates);

" Litigation support (cost recovery actions, critical review of environmental documentation, cost benefit analysis, feasibility review, Gas Research Institute guidance review); and

" Public awareness and employee presentations (utility employees, AFL-CIO, community representatives).
