(Shaw) has been contracted by the U.S. Army Corps of Engineers (USACE) to perform a Site Investigation (SI) for sediment within the unnamed tributary of Patroon Creek, Patroon Creek, and the Three Mile Reservoir. These three Areas of Concern (AOCs) are located downstream of the Colonie Formerly Utilized Sites Remedial Action Program (FUSRAP) Site. The SI is being conducted to evaluate if radiological contamination resulting from historical site operations conducted at the Colonie FUSRAP Site has impacted the sediment at the three AOCs. The Colonie FUSRAP Site is located in the Town of Colonie, Albany County, New York (Exhibit 1-1). The three AOCs for this work plan are as follows: the unnamed tributary from where it leaves the Colonie FUSRAP Site to where it discharges to Patroon Creek; Patroon Creek from the confluence of the unnamed tributary to Three Mile Reservoir; Three Mile Reservoir, and just downgradient of Three Mile Reservoir. Exhibit 1-2 shows the general location of the three AOCs discussed in this Work Plan. This work is being performed for USACE under the Kansas City (KC) District Pre-placed Remedial Action Contract (PRAC) DACW41-01-D-0031 Delivery Order DA02. Sediment data has previously been collected from the unnamed tributary, Patroon Creek, and the Three Mile Reservoir by the U.S. Department of Energy (USDOE), USACE, the U.S. Environmental Protection Agency (USEPA), and State University of New York at Albany (SUNY) from 1984 to present. This data, which is presented in the Technical Memorandum Overview of Patroon Creek Watershed (USACE, 2003a) indicated that uranium, thorium, and lead were present in the sediments that are assumed to have originated from the Colonie FUSRAP Site. Therefore, this SI Work Plan has been developed to more accurately assess the nature and extent of contamination present within the three AOCs. The field efforts presented herein were developed during a Technical Project Planning (TPP) meeting held in Colonie, NY on July 16, 2003 between USACE - New York District, USACE - Baltimore District, USACE Hazardous, Toxic, and Radioactive Waste Center of Expertise (HTRW CX), New York State Department of Environmental Conservation (NYSDEC), USEPA, County of Albany Department of Health (DOH), and SUNY Albany. Data gathered during the SI will be presented and discussed in a report to be prepared upon completion of all field activities associated with the SI. This Work Plan is to be used in conjunction with the associated SI Sampling and Analysis Plan (SAP; USACE, 2003b), which includes a Field Sampling Plan (FSP) and Quality Assurance Project Plan (QAPP) component. In addition, an SI Health and Safety Plan (HASP, USACE, 2003c) has been prepared, which lists guidelines and procedures to be followed during all field activities. The SAP and the HASP are being submitted under separate cover. The field activities associated with this SI will fully comply with the requirements presented in these documents.

DACW41-01-D-0031 1-1 Site Investigation Work Plan PRAC DA02-9 Unnamed Tributary, Patroon Creek, and Three Mile Reservoir October 2003 Final Document The three AOCs, the unnamed tributary of Patroon Creek, Patroon Creek, and Three Mile Reservoir, are located within the Town of Colonie and the City of Albany, Albany County, New York (Exhibit 1-2). The unnamed tributary intersects with Patroon Creek approximately 2 miles down stream from the Patroon Creek Headwaters (Six Mile Reservoir). Patroon Creek generally flows west to east through Three Mile Reservoir and eventually empties into the Hudson River in the City of Albany. Patroon Creek is designated as a Class C Water Body (suitable for primary / secondary contact recreation and suitable for fish propagation and survival) in the New York State Section 303(d) List of Impaired Waters. 2.1 PHYSICAL SETTING 2.1.1 Demography The AOCs are located primarily within a mixed industrial and residential area. The portion of the unnamed tributary of concern to be investigated originates at the Colonie FUSRAP Site. The Colonie FUSRAP Site is an industrial site located within a commercial and residential area. The tributary flows underneath Yardboro Avenue, which contains residential and light industrial properties, before it enters into Patroon Creek. The portion of Patroon Creek of interest and Three Mile Reservoir are both bounded on their southern side by New York Interstate 90 (I-90) and on their northern side by industrial properties (including a high-speed railroad line). Aerial photographs of the AOCs may be found in Appendix B. 2.1.2 Physiography and Topography The AOCs are located on the eastern edge of the Central Plateau physiographic province, with the Adirondack province to the north and the Valley and Ridge provinces to the east. The AOCs are located within the Pine Bush Area of the Mohawk-Hudson lowland. The unnamed tributary bed ranges in elevation from approximately 208 feet above Mean Sea Level (MSL) at the Colonie FUSRAP Site to approximately 200 feet above MSL at the confluence with Patroon Creek. The area of interest along Patroon Creek and Three Mile reservoir ranges in elevation from 200 feet above MSL at the unnamed tributary confluence to 194.8 feet above MSL at the overflow weir of the Three Mile Reservoir dam. 2.1.3 Surface Water Hydrology The unnamed tributary of Patroon Creek drains an area of approximately 300 acres in the Town of Colonie. The stream begins to the north of Central Avenue and is routed underground into the Colonie storm sewer system. The unnamed tributary is in an urban area, therefore, the stream has been significantly altered. During the early 1900s, a dam was constructed on the unnamed tributary within the Colonie FUSRAP Site to form Patroon Lake. In the 1960s, a 320-foot section of the Patroon Creek was relocated by the construction of Interstate 90. The unnamed tributary of Patroon Creek enters on the western side of the Colonie FUSRAP Site, and is conveyed approximately 150 ft to the south and east within a channel lined with rip rap before it enters a culvert headwall and is directed underground across the Colonie FUSRAP Site in a 48-inch concrete culvert. The culvert drainage exit is located south of the Colonie FUSRAP Site, directly south of the CSXT railroad tracks. Downstream from the railroad track and Yardboro Avenue, the stream is an open channel, approximately 600 ft long, before it intersects Patroon Creek. Based on surface water elevations measured at two staff gauges located at the Colonie FUSRAP Site, and in the upward gradients observed in nearby wells, it appears that shallow groundwater discharge occurs along the stream. Patroon Creek drains an area of approximately 13 square miles in Colonie and Albany. The drainage basin is mostly urban with commercial and residential properties. The creek is approximately 7 miles from its headwaters to where it discharges into the Hudson River. Patroon Creek is a perennial stream. The U.S. Geological Survey (USGS) measured the base flow in Patroon Creek from 1978 to 1980 at a location approximately 0.4 miles downstream of the Colonie FUSRAP Site. The base flow measurements ranged from 5.37 -13.8. cubic feet per second (cfs). Review of aerial photographs from 1942, 1968, and. 1977, for the Three Mile Reservoir area, indicate that Three Mile Reservoir was originally composed of two basins. A dividing dam and spillway

separated one basin located to the west from a second basin located to the east. It is apparent when comparing the 1942 and 1968 photographs that I-90 has been built across Three Mile Reservoir, destroying the western basin and significantly reducing the size of the eastern basin. NYSDOT Construction Drawings for I-90 confirm that the dam and gate of the western basin have been removed, and I-90 was constructed over approximately 75% of the western basin and approximately 50% of the eastern basin. 2.1.4 Regional Geology The major geologic features in the vicinity of the three AOCs are the Colonie Channel and Glacial Lake Albany. The Colonie Channel is a buried glacially scoured valley that occupied the Hudson- Champlain lowlands of east-central New York. The channel was formed in the Snake Hill Shale of the Ordovician age. Glacial Lake Albany formed within this channel during the glaciation of the Hudson Valley. The lacutstrine silts, clays, and sands present today over the bedrock basement were deposited in Lake Albany. The general stratigraphy in the area of the AOCs, in order of decreasing depth is (Dineen and Hanson, 1983): Till: Compact, dark gray, bouldery to gravelly clay till 1 to 31 meters (m) in thickness occurring just above the bedrock in the Coionie Channel between Delmar and Saratoga Lake, New York. Lake Silts and Clays: Soft to hard gray, reddish-gray, yellow, or brown lake silts and clay 1 to 60 m thick. Contains 0.1 to 15 cm thick varves of clay grading down to silt. The lower 3 m and upper third of the formation is dominated by sandy silt. Lake Sand, Lake Silty Sand, and Dune Sand: Very light yellow brown to light gray, ripple laminated to horizontally laminated fine to medium sand with thin (0.3 to 1 m) silt and clay lenses. This formation varies in thickness from 1.5 m to 30 m. The sand contains up to 30-percent silt, with the higher percentage occurring with greater depth. 2.1.5 Regional Hydrogeology There are three primary aquifers in this region, listed from shallow to deep, they are as follows: Pine Bush Surficial Sand Aquifer: The Pine Bush aquifer, as described by Dineen (1982) was formed by deposition of sand in glacial Lake Albany and by wind-blown sand that formed dunes during and after the lake levels drained. At the eastern edge of the aquifer, the wedge of sands thins quickly in the area of glacial Lake Albany where shallow water sandbar deposits transitioned to deeper water silts and clays (Dineen, 1982). Colonie Channel Buried-Valley Aquifer: The Colonie Channel buried-valley aquifer consists of coarse-grained stratified drift deposits within the Colonie Channel, which is part of a network of buried valleys. The aquifer is separated from the overlying Pine Bush Surficial Sand Aquifer by a thick sequence of lacustrine silt and clay, except along the buried-valley margins, where the surficial sand may immediately overlie the stratified drift. Groundwater occurs under confined conditions in much of the aquifer. Wells penetrating this aquifer in topographically low areas have shown water flowing at the ground surface (Arnow, 1949). Waller (1983) suggests that the recharge to the buried-valley aquifer occurs where surficial stratified drift deposits are hydraulically connected to the aquifer. Discharge from the buried-valley aquifer is thought to occur by upward leakage through the lacustrine silt and clay deposits, by seepage into Shaker Creek, by flow into permeable zones within the Mohawk River floodplain deposits, and by pumping of water-supply wells. Snake Hill Shale Bedrock Aquifer: The Snake Hill Shale bedrock aquifer is a folded shale, with local layers of limestone and sandstone (Halberg et al., 1964). Recharge, discharge, and groundwater-flow relationships are not well understood for this aquifer.

2.1.6 Conceptual Site Model A conceptual site model (CSM) for the contaminant sources, release mechanisms, and potential human exposure mechanisms was developed for Ratroon Creek and presented in the Technical Memorandum Overview of Patroon Creek Watershed (USACE, 2003a). The CSM is presented as Exhibit 2-1. 2.1.6.1 Release Mechanisms The first release mechanism described in Exhibit 2-1 is surface runoff/flooding. During the time period that the facility was operational, the Colonie FUSRAP Site could be divided into two separate drainage areas. The eastern drainage area covered approximately 37 percent of the Colonie FUSRAP Site and included runoff from part of the main site building roof and parking areas. Overland flow from this section drained into a storm sewer that discharged directly into Patroon Creek. The western drainage area, which covered the remaining 63 percent of the Site, included part of the site building roof, the parking areas, and the grassy areas. All runoff from the western area flowed into the unnamed tributary of Patroon Creek. The next release mechanism is airborne deposition. Airborne emissions during the electropolishing operation for plating uranium at the Colonie FUSRAP Site caused documented airborne releases of uranium. These emissions caused uranium to be deposited to surrounding buildings, soil, and surface water bodies. The last release mechanism presented on Exhibit 2-1, infiltration of groundwater into Patroon Creek, is not considered a complete pathway. While Patroon Creek is a gaining creek, it is believed that only water is discharged, and that particulates do not discharge. As uranium or metals such as lead adheres or adsorbs to particulate matter, release through groundwater is not considered to be a significant release mechanism. 2.1.6.2 Sediment Entrainment Contaminant Transport Mechanism Sediment is transported in suspension, as bed load rolling or sliding along the bed and interchangeably by suspension and bed load. The nature of movement depends on the particle size, shape, and specific gravity in respect to the associated velocity and turbulence. Silt size particles may move either in suspension or as bed load in low-gradient, low-velocity channels, e.g., drainage ditches (American Society of Civil Engineers [ASCE], 1977). Therefore, contaminants released directly to the unnamed tributary of Patroon Creek and Patroon Creek may be transported downstream, thereby impacting other water features. It is through this transport mechanism that Three Mile Reservoir could have been impacted by activities that were conducted at the Colonie FUSRAP Site. 2.1.6.3 Human Exposure Mechanisms Humans can be exposed to contaminants in sediment and surface water via ingestion, dermal contact, and inhalation or dust (during droughts). 2.2 SITE HISTORY AND PREVIOUS INVESTIGATIONS 2.2.1 Site History Historical documentation indicates that during the 17th Century Patroon Creek served as a source of power for a number of grist and saw mills and it became a major source of water for the growing Albany population. In the early eighteen hundreds, the privately owned Water Works Company created Tivoli Lakes using a portion of the watershed area of Patroon Creek as part of their water supply system for the City of Albany. In 1850, the Albany Board of Water Commissioners was formed and purchased Albany's water supply from the Water Works Company. Under the management of the Albany Board of Water Commissioners, Six Mile Reservoir was created to help supply water to the growing Albany population by damming three streams at the Patroon Creek headwaters. In the late Nineteenth Century Patroon Creek water supply consisted of Six Mile Reservoir, Sand Creek Reservoir, Three Mile Reservoir and the Tivoli Lake Reservoir. This system of reservoirs would remain a source of water for the City of Albany until the early 1920's. Due to contaminant issues associated with the proximity of the railroad and sanitary and

DACW41-01-D-0031 2-3 Site Investigation Work Plan PRAC DA02-9 Unnamed Tributary, Patroon Creek, and Three Mile Reservoir October 2003 Final Document Section 2.0 Overview of Site Conditions stormwater runoff, the City of Albany discontinued the use of the reservoir systems in the early 1920's and began to utilize other water supply sources. In the early 1980s, due to ongoing environmental concerns, the NYSDEC designated the Patroon Creek as a Class C Water Body in the New York Sate Section 303 (d) List of Impaired Waters. Portions of the Patroon Creek watershed have also been designated as Areas of Concern by the NYSDEC. Upon review of environmental databases, conversations with the NYSDEC and USEPA, and review of relevant documents, four sediment investigations were identified for the AOCs. These include: • USDOE/USACE investigations at the Colonie FUSRAP Site (discussed in Section 2.2.2); • USEPA investigation of Mercury Refining; . • SUNY investigation of Patroon Creek under USEPA Environmental Monitoring for Public Access and Community Tracking (EMPACT) Grant; and, • NYSDEC - Patroon Creek. Mercury Refining is a USEPA National Priority List (NPL) site located along Patroon Creek between Six Mile Reservoir and Three Mile Reservoir. Mercury Refining is located off of Railroad Avenue and on the North Branch of the Patroon Creek at 26 Railroad Avenue in the Town of Colonie, New York. In the late 1980s, the NYSDEC performed an in-depth study of fish populations, surface water quality and sediment quality within the Creek. Between 1999 and 2002, Dr. John G. Arnason at SUNY collected a sediment core from within Three Mile Reservoir to evaluate the deposition of cadmium, mercury, lead, and uranium in the reservoir's sediments. Additional industrial sites (including General Electric Vetrano Road (NYS Superfund Site) and Tobins First Prize) are located in the vicinity of Patroon Creek, however, based on the information reviewed to date, they do not appear to be a source of radiological or metal contamination to the AOCs. A detailed discussion of the Colonie FUSRAP Site, Mercury Refining Site, and the investigative work performed on Patroon Creek is provided below. 2.2.2 Colonie FUSRAP Site Industrial operations at the Colonie FUSRAP Site began in 1923, when the Embossing Company purchased a portion of the present-day site to construct a facility for manufacturing wood products and toys. In 1927, Magnus Metal Company, Inc. (Magnus) purchased the property and converted the facility to a brass foundry for manufacturing railroad components. Magnus cast the brass components in sand molds and also manufactured brass bearing housings with surfaces of Babbitt metal (an alloy of lead, copper, and antimony). Preparation of the bearing surfaces for bonding with the brass housing involved degreasing of the bearings by immersion in an acid bath (BNI, 1992). In 1937, National Lead (NL) purchased the facility, continued the brass foundry operations initiated by Magnus, and bought an adjacent lot that contained a portion of Patroon Lake. Prior to 1941, NL began filling Patroon Lake with used casting sand. After World War II, the plant began casting aluminum mainframes for jet airplanes. In 1958, the nuclear division of NL began producing items manufactured from uranium and thorium under a license issued by the Atomic Energy Commission (AEC). NL discontinued its brass foundry operations in 1960. Between 1958 and 1984, NL carried out a number of processes using radioactive materials consisting primarily of depleted uranium, but also with lesser amounts of thorium and enriched uranium. The plant handled enriched uranium from 1960 to 1972. From 1966 to 1972, NL held several contracts to manufacture fuel from enriched uranium for experimental nuclear reactors. Operations at the plant reduced depleted uranium tetrafluoride to depleted uranium metal, which was then fabricated into shielding components, ballast weights, and projectiles. During this period, the AEC issued licenses to NL for possession of uranium and special nuclear material, and the State of New York issued a license for fabrication of depleted uranium parts. As a result of NL's operations, residual radioactive materials were found at the site buildings, grounds, and surrounding residences and businesses. Other processes conducted at the plant included an electropolishing operation for plating uranium with nickel and cadmium. Chemicals used in the plating operation included tetrachloroethene (PCE),

DACW41-01-D-0031 2-4 Site Investigation Work Plan PRAC DA02-9 Unnamed Tributary, Patroon Creek, and Three Mile Reservoir October 2003 Final Document Section 2.0 Overview of Site Conditions

nickel sulfamate, sodium cyanide, ferric chloride, nitric acid, silicate phosphate, iridite (a chromium brightener), cadmium metal, nickel metal, and boric acid. The location and method of disposal for most of these materials is unknown, because very few disposal records could be located; however, NL's letters indicate that, under an AEC license, approximately 42 cubic meters (m3) of graphite, slag, refractory uranium oxide, insoluble oil, metal scrap, and burnable trash were buried in the Patroon Lake area by 1961 (Huss, 1959; Wilson, 1962). Chemical wastes and packaged chemicals used at the Colonie FUSRAP Site, included: acids, bases, degreasing agents, carbon tetrachloride, benzene, polychlorinated biphenyls (PCBs), cyanide, heavy metals, and asbestos. The chemicals present on the Resource Conservation and Recovery Act (RCRA) Part A permit application were removed from the Colonie FUSRAP Site as part of the closure of the Colonie FUSRAP Site as an interim RCRA storage facility. New York State Officials closed NL in 1984, and Congress authorized USDOE to conduct a removal action at the property. In February 1984, the Secretary of Energy accepted an offer from NL to donate the land, buildings, and equipment to USDOE to help expedite the cleanup. In 1985, USDOE acquired a portion of the NiMo property bordering the Colonie FUSRAP Site to the north and northwest, and subsequently designated it as part of the Colonie FUSRAP Site. From 1984 to 1995, the Colonie FUSRAP Site was used for interim storage of radioactive materials removed from the affected properties and businesses (USDOE, 1986; 1989). At the time USDOE took ownership of the former NL property, both the AEC and State licenses were administratively terminated, since USDOE-owned facilities are not subject to regulation by the Nuclear Regulatory Commission (NRC) successor licensing agency to AEC, or the State. In 1992, the USDOE initiated actions to prepare the main Colonie FUSRAP Site Building for a removal action, including preparation of an Engineering Evaluation/Cost Analysis (EE/CA) (USDOE, 1993). In September 1995 (USDOE, 1995), an EE/CA to address the removal action at the Colonie FUSRAP Site was finalized. Following approval of the EE/CA, the Action Memorandum (USDOE, 1997), designating Alternative 3B from the EE/CA as the selected removal alternative, was issued. Subsequent activities have included the dismantling of all facility buildings and initiation of excavation as part of the 1997 Action Memorandum. Sediment sampling near the Colonie FUSRAP Site was performed within the unnamed tributary, Patroon Creek between the Northern Branch and Three Mile Reservoir, and within Three Mile Reservoir. Between 1984 and 2001, sediment samples were typically collected at the Colonie FUSRAP Site sampling location (where the unnamed tributary runs through the Colonie FUSRAP Site) and at up to three additional sample locations downstream of the Colonie FUSRAP Site in the unnamed tributary. In 1992, the sediment sampling program was modified to include; one background sample in the unnamed tributary upstream of the Colonie FUSRAP Site, one sample in the unnamed tributary downstream of the Colonie FUSRAP Site, one background sample at the confluence of the Northern Branch and Patroon Creek, and four sediment samples between the unnamed tributary and the Three Mile Reservoir dam. The USDOE and USACE sediment samples were collected at various depths ranging from surface grab samples to approximately 4.5 feet below the bottom of the Creek. All sediment samples were analyzed for radiological contaminants of concern. In addition in 1992, 1999, and 2001 metals were included in the analyses. The 2001 sediment investigation also included total organic carbon, volatiles and semivolatiles in the sediment analyses. Exhibit 2-2 presents the radiological data gathered from these investigations. Sediment sample results were compared with the USDOE criteria of 45.84 pCi/g for total uranium in soils and 5 pCi/g for radium and thorium. Due to the absence of standards for sediment, the DOE residual surface soil clean-up criteria for radium and thorium isotopes (Order 5400.5) and the CISS site- specific DOE soil clean-up criterion for uranium-238 are used as a basis for evaluating analytical results for sediment. If a mixture of these radionuclides is present, the sum of the ratios of each isotope must be less than one. The results of the USDOE/USACE sediment sampling from 1984 through 1998 (Exhibit 2- 2) were relatively consistent. The upstream (background) locations had levels in the range of 0.68-6.5 pCi/g for total uranium. Locations in the Patroon Lake area (on-site) had the most elevated levels, with levels of 278 pCi/g in 1989 and 158.4 pCi/g in 1990. The downstream locations all had levels below the 45.84 pCi/g criteria except for a sample taken in 1992 at the culvert outfall just downgradient from the

Colonie FUSRAP Site along the unnamed tributary which had a total uranium level of 128.3 pCi/g at a depth of 1.5-2.5 feet. The results from the 2001 Sediment Sampling Report (6 upstream locations, 6 downstream locations) show an upstream range of 0.261 - 0.841 pCi/g and a downstream range of 0.195 -7.06 pCi/g. The results indicate all samples are well below the 45.84 pCi/g criteria. 2.2.3 Mercury Refining, Inc. Mercury Refining, Inc. is a former battery reclamation facility located at 26 Railroad Avenue in the Town of Colonie, New York. The half-acre site is located near the Northern Branch of Patroon Creek in a light industrial and commercial area. Mercury reclamation operations were performed at the Mercury Refining site from 1956 to 1998 and the property is currently used as a transfer facility for waste material which is shipped off-site for mercury reclamation. Based on USEPA's Site Fact Sheet (USEPA, April 2002), operators at the Mercury Refining site historically dumped waste batteries behind an on-site furnace building until 1980. These operations resulted in soil, groundwater, and sediment contamination. The Mercury Refining site has been under active investigation and remediation since the early 1980's and the primary constituents of concern are: mercury, lead, and PCBs in the soil; cadmium, mercury, and lead in groundwater; and mercury, lead, and PCBs in the sediments of the Northern Branch of Patroon Creek and Patroon Creek itself. In 1983, Mercury Refining was placed on the NPL and in 1985 the NYSDEC issued the first Consent Order to Mercury Refining to conduct remedial activities at the site. Under this order, 2,100 cubic yards of mercury laden soil and debris and 300 cubic yards of PCB contaminated soil were excavated and disposed of off-site. During the remedial activities, additional contamination was found beneath the furnace building. This material was sealed in plastic sheeting and left in place. The property was then re- graded and capped to prevent rainwater infiltration. In 1989, the NYSDEC issued a second Consent Order, requiring Mercury Refining to curtail any further chemical releases to the environment. In early 1993, the NYSDEC issued Mercury Refining a third Consent Order requiring Mercury Refining to clean-up the remaining on-site contamination, provide long-term monitoring of on-site soil and groundwater, and assess off-site soil conditions and sediment conditions within Patroon Creek. In 1996, the NYSDEC issued a Hazardous Waste Corrective Action permit requiring the control, generation and storage of hazardous waste on-site. The Permit also required Mercury Refining to remediate, remove and continue to monitor on-site soil and groundwater impacts and off-site soil impacts and sediment quality within of Patroon Creek. In November 1999, the NYSDEC requested that USEPA assume the role as the managing regulatory agency due to Mercury Refining's non-compliance with the Orders and Permit. Since 1999 USEPA has been conducting a Remedial Investigation/Feasibility Study (RI/FS) at the Mercury Refining Site and Patroon Creek. To date, no documents have been released to the public. Some additional groundwater sampling was collected after the final review process for the Rl, which is near completion. The USEPA has postponed issuing the FS at this time and has now scheduled for completion date of May 2004. An alternative electrochemical technology for mercury remediation is being considered for treatment and a treatability study for this technology is currently in process of being initiated. Shaw has been in communication with the USEPA project manager and has obtained USEPA's data for Patroon Creek sediment sampling. This information is presented graphically on Exhibit 2-3. The data indicates that twelve locations were sampled along the North Branch and Patroon Creek to just below the spillway of Three Mile Reservoir. Background samples were also collected upstream on the North Branch at Inga's Pond and upstream of the confluence of the North Branch and Patroon Creek near Six Mile Reservoir. Surface water and sediment samples were collected at all sampling locations. At five locations fish samples were also collected. Review of the data indicates that slightly elevated concentrations of mercury and lead are present in the sediments of the North Branch, within the sediments of the Patroon Creek (downstream of the confluence of the North Branch and Patroon Creek) and within Three Mile Reservoir. Elevated concentrations of PCBs were also detected in the sediments of Three Mile Reservoir just before the dam. Radiological sampling was not performed. USEPA has not released any preliminary clean-up goals to date.

2.2.4 State University of New York at Albany In 2002, USEPA awarded an EMPACT grant to the Patroon Creek Monitoring, Management and Restoration Program (PCMMRP) to establish Patroon Creek as a living classroom to promote awareness and stewardship and to provide the public with time relevant data about the Patroon Creek Watershed. In addition, the grant was to establish an environmental and public health network that paid special attention to urban neighborhood concerns. The PCMMRP, lead by Robert F. Cross, Commissioner, City of Albany, Department of Water, is a consortium of interested parties including: the City of Albany, the Arbor Hill Environmental Justice Corporation, the W. Haywood Burns Environmental Education Center, University at Albany, Albany Pine Bush Preserve Commission, Albany County Department of Health, NYSDEC, USGS, Rennselaer Polytechnic Institute, Essential School at Albany High School, Hudson Basin River Watch, and Clearwater Chapter of Trout Unlimited. In addition to the USEPA EMPACT Grant, the PCMMRP received funding from the NYSDEC in 2002 to establish two monitoring stations along Patroon Creek. Under this program, Dr. John G. Arnason of SUNY conducted a depositional study of cadmium, mercury, lead, and uranium in the sediments of Three Mile Reservoir. In 1999, SUNY collected a 3-meter long sediment core from the downstream end of Three Mile Reservoir in approximately 2.5 m of water. Reportedly, this sampling location was chosen because coring could be advanced to a greater depth, and the sediments were less likely to be disturbed. SUNY collected bulk sediment samples from the core at 0.05-meter intervals and analyzed the samples for total cadmium, lead, mercury and uranium. SUNY's study indicated that total uranium concentrations range from approximately 1 milligram per kilogram (mg/kg) to 320 mg/kg at depths of reservoir bottom to 1.7 meters below reservoir bottom. At depths greater than 1.7-meter concentrations of total uranium ranged from 1 mg/kg to 2 mg/kg. The most elevated concentration of total uranium (320 mg/kg) was found at approximately 1.6 meters below creek bottom. SUNY found that total cadmium, lead and mercury displayed similar patterns, with the deepest portion of the core having the lower concentrations and the mid-section of the core (0.75 meters to 1.5 meters below creek bottom) having the most elevated concentrations. Based on correlation of historical industrial activities with the concentration profiles, SUNY concluded that estimated minimum average sedimentation rate in Three Mile Reservoir from 1955 to 1999 is approximately 0.04 meters per year with a minimum depositional rate of approximately 28 kg per square meter per year. SUNY correlated the data and depositional depth with the previous industrial practices along Patroon Creek. SUNY suggests that the concentration profiles of cadmium, mercury, lead, and uranium represent industrial pollution related to the Mercury Refining and National Lead sites from the mid-1950's to the present day. After SUNY had finished the field work for this study, NYSDEC requested to share samples with SUNY for verification purposes. SUNY honored this request and supplied split samples to the NYSDEC. In a letter to SUNY, dated Feb. 2003, the NYSDEC provided SUNY with their analytical results for isotopic uranium, which confirmed the presence of depleted uranium. The NYSDEC results confirm the presence of depleted uranium above the 35 pCi/g cleanup criteria established for the Colonie FUSRAP Site in one interval of the sediment sample collected by SUNY (Uranium-238, or U-238 at 167 centimeters (cm) below ground surface (bgs)). In addition to SUNY's investigation, the USGS and Dr. George Robinson at SUNY of Albany are currently collecting additional information about Patroon Creek under the PCMMRP. The USGS provides real-time stream gauging data and water quality information to the public under the W. Haywood Burns Environmental Justice Corporation Website. Dr. Robinson is currently completing his study of the Riparian Zone and Wetlands of Patroon Creek and is anticipating completing his study in late 2003. 2.2.5 New York State Department of Environmental Conservation In the late 1980s, the NYSDEC performed an in-depth study of fish populations, surface water quality and sediment quality within the Creek. Allegedly the results of this investigation led to the designation of the Creek as a Class C Water Body in the New York State Section 303 (d) List of Impaired Waters. The specific information and data collected during the NYSDEC study has not been received as of the date of this submittal. If available from the NYSDEC, this 1980's data/information will be utilized to update the Sediment Sampling Work Plan and will be included in the SI Report.

2.2.6 Site-Specific Sampling and Analysis Problems The site-specific problems associated with sampling at the unnamed tributary of Patroon Creek, Patroon Creek, and Three Mile Reservoir include potentially heavy underbrush, steep banks to the water bodies, and marshy conditions. These conditions can be overcome by finding better access points and/or performing moderate clearing (only what can be easily accomplished manually). Rights of Entry will be required for sampling all locations not on the Colonie FUSRAP Site property. These properties are owned by the CSX railroad, NYDOT, Niagara Mohawk, and the City of Albany. USACE has initiated Rights of Entry discussions with these landowners.

Male Associates, L.S. is the surveying subcontractor for the Colonie FUSRAP Site and, as such, is familiar with the scope of work and the Project Team. 3.4 PROJECT CONTROLS This section describes procedures for cost and schedule control for this field effort. As previously discussed in Section 3.3, Shaw has established a management team to ensure that all work is performed in a timely manner and that procedures and plans are followed. The project team members will oversee the planning, field, and/or reporting phases of the project. Management team project review meetings will be conducted to ensure that the field efforts are being performed efficiently and safely. The Project Manager will be responsible overall for the performance of the project including ensuring the work is being performed efficiently and that approved procedures are being followed. The Project Manager will oversee and track project tasks both from a schedule and cost perspective. The Project Manager, who is integral in establishing the project schedule, will track the progress of field operations on a daily, weekly, and monthly basis to ensure operations are running as planned. If activities are running behind or ahead of schedule, the Project Manager will be responsible for reporting schedule variances to USACE, as they become apparent. During field operations, the Project Manager will be responsible for ensuring that operations are being performed in an efficient manner. If efficiency becomes a concern, the Project Manager will be the primary driver for corrective measures. 3.4.1 Cost Control and Tracking Costs will be tracked by the Project Manager and Project Cost Engineer. In order to track costs, labor, equipment, supplies, etc. utilized in the field will be tracked by the FOL and submitted to the Project Cost Engineer who will convert the resources into costs. The Project Cost Engineer will submit this information to the Project Manager who will utilize the information to make project adjustments as necessary to optimize project efficiency as well as perform monthly reporting to USACE. Monthly reporting to USACE will be in the form of cost tables showing monthly expenditures, expenditures to date, committed costs, estimate to complete, budget, and variance information. Also, as stated above, the project costs will be loaded into the schedule monthly and graphically shown in the form of histogram or curvilinear plot with the schedule. The details concerning any positive variance (i.e., cost growth) in the cost tables will be discussed in the monthly report. These cost control methods will be used to project additional budget needs necessary for the successful completion of the project. In addition, the report will include a baseline projection of expected monthly expenditure for each major work activity. Over the course of the project, two deliverables will be submitted regularly to USACE that discuss the project performance and/or cost management. These deliverables include the daily QC Report and Monthly Cost and Performance Report (CPR), Daily QC Report: Details of the report are discussed in the SAP. The Daily QC Report will be submitted to the on-site USACE Project Engineer within 2 working days after the reporting date. Monthly Cost and Performance Report: The monthly CPR will be prepared by the Project Manager. This report will discuss the activities conducted in the month past and report the project costs for the month and costs to date. The cost control and tracking information will be provided in this report. Specifically, the CPR will include the following topics:

The project costs will also be loaded into the Primavera schedule monthly and graphically shown in the form of histogram or curvilinear plot with the schedule plot. 3.4.3 Records Management Shaw will maintain records of all data collected and related files. All files, including data, lists, excavation results, photographs, and maps, will be organized and will be filed. Electronic files of data, maps, QA/QC data, contaminant profiles and other pertinent information will be properly archived. Reports and submittals will be provided to USACE as specified in the SOW.

DACW41-01-D-0031 3-4 Site Investigation Work Plan PRAC DA02-9 Unnamed Tributary, Patroon Creek, and Three Mile Reservoir October 2003 Final Document Sediment sampling is proposed for the unnamed tributary of Patroon Creek, Patroon Creek, and the Three Mile Reservoir. In addition, sediment samples will also be collected upstream of the location where the unnamed tributary intersects Patroon Creek and downstream of the Three Mile Reservoir. A discussion of the work to be completed and the rationale for the sampling is presented in this section. 4.1 RATIONALE The scope for sampling activities described herein was developed through assessment of existing sampling data collected by the USDOE, USACE, and USEPA from 1984 to present. A Technical Project Planning (TPP) meeting was held in Colonie, NY on 16 July 2003 to discuss the historical data and develop an approach for completing the SI. The TPP minutes may be found in Appendix C. The TPP was attended by representatives of USACE, New York and Baltimore District, USACE HTRW CX, NYSDEC, USEPA, County of Albany DOH, and SUNY. As discussed in Section 2.2.4, sediment sampling performed by SUNY Albany has indicated the presence of radiological contamination in the Three Mile Reservoir. This data is presented in detail in the Technical Memorandum Overview of Patroon Creek Watershed (USACE, 2003a). The scope of this Work Plan is to define the radiological impacts within the sediments of the unnamed tributary after it exits the Colonie FUSRAP Site to its terminal point at Patroon Creek, a section of Patroon Creek between the unnamed tributary confluence and Three Mile Reservoir, and Three Mile Reservoir. On the Colonie FUSRAP Site, the government, as owner of the site, is responsible for addressing all contaminants. The government's responsibility on the vicinity properties, however, is limited to FUSRAP-related contaminants. Although Patroon Creek has not been named as a vicinity property, this investigation will focus on radioactive contamination. Any other contamination will be evaluated for disposal and worker safety purposes. The project-specific objectives are to determine the absence/presence of radioactive contamination as a result of past industrial operations conducted at the Colonie FUSRAP Site that may have allowed radioactive contamination to migrate into the AOCs. If radiological contamination is detected, the level of non-radiological metals contamination will be determined to aid in evaluations of waste acceptance criteria and worker health and safety requirements. All analytical data received from the laboratory will be fully validated by a Shaw chemist. After the completion of field activities and data validation, an SI Report will be completed to present and discuss analytical data. A discussion on the fate and transport of contaminants will also be included in the SI Report. 4.2 SAMPLING PROGRAM The sampling program includes sample location selection, surveying, collection of sediments samples, analysis for radiological contamination, and analysis for non-radiological contamination in the areas where radiological contamination is determined to be present. A discussion of these work elements is presented in this section. 4.2.1 Sampling Locations and Rationale The locations where sediment samples are to be collected include: • Along Patroon Creek Upstream of Colonie FUSRAP Site; • Unnamed tributary, after it exits the Colonie FUSRAP Site; • Patroon Creek from the unnamed tributary to Three Mile Reservoir; • Three Mile Reservoir; and, • Downstream of Three Mile Reservoir. A total of 29 sample locations have been selected along the AOCs (Exhibit 4-1). These locations represent areas where surface water transport mechanisms would likely deposit sediment carried from the Colonie FUSRAP Site. The specific locations and the rationale for their selection is as follows:

DACW41-01-D-0031 4-1 Site Investigation Work Plan PRAC DA02-9 Unnamed Tributary, Patroon Creek, and Three Mile Reservoir October 2003 Final Document Section 4.0 Field Activities

• Along Patroon Creek Upstream of Colonie: One sample (CSD-US1) will be collected upstream of the Colonie FUSRAP Site (Exhibit 4-1). • Unnamed Tributary of Patroon Creek: A total of seven samples (CSD-UT1 through 7 on Exhibit 4-1) are to be collected from locations along the unnamed tributary that crosses the Colonie FUSRAP Site. Two sets of three transects (samples CSD-UT1/2/3 and CSD-UT5/6/7 on Exhibit 4-1) will be collected to represent a cross-section of the creek to account for various flow/sedimentation conditions. • Patroon Creek: A total of four samples (CSD-PC1 through 4 on Exhibit 4-1) are to be collected from locations along Patroon Creek. One sample will be collected at the point where the Unnamed Tributary meets Patroon Creek. One sample is to be collected at a point between the convergence.of the Unnamed Tributary meets Patroon Creek and before the sedimentation pool. One sample is to be collected from the sedimentation pool before Central Avenue and one sample is to be collected between Central Avenue and Three Mile Reservoir. • Three Mile Reservoir: Samples will be collected from a total of fifteen sample locations (CSD- 3MR1 through 15). Transect locations have been selected near the dam as that is where the previous core sample showed contamination and at the beginning of the transition section between Patroon Creek and Three Mile Reservoir where the old sedimentation basin was located and where the wetlands begin. In addition, two transects (CSD-3MR5/6/7 and CSD- 3MR9/10/11) were selected as midpoints between the other two transects. Single sampling points (CSD-3MR4, CSD-3MR8 and CSD-3MR12) were located between transects along the path of the main flow. It is anticipated that the transects and individual points should provide information to determine the absence/presence of radiological contamination. • Downstream of Three Mile Reservoir: A total of two samples (CSD-DS1 and CSD-DS2) will be collected from locations downstream of the dam at the Three Mile Reservoir. The sample locations will be selected in areas of sedimentation to determine if the material has moved downstream of Three Mile Reservoir (Exhibit 4-1). 4.2.2 Surveying The initial sample locations will be surveyed and staked (or marked) using Differential Global Positioning System (DGPS) prior to mobilization of the field sampling team. The field team will track sample information on the chain of custodies and other field log using initial and any revised location coordinates and data recorded sheets. 4.2.3 Sample Collection and Field and Laboratory Analysis Sediment samples will be collected for radiological analysis as indicated on Exhibit 4-2. Samples will be placed in the containers specified on Exhibit 2-3 of the SI SAP (USACE, 2003b). Samples from all of the AOCs will be logged for stratigraphic characterization and all samples will be analyzed on-site for radiation screening. Sediment core samples in the AOCs will be field screened using a Pancake Geiger- Mueller (PGM) detector (Edi SOP 5.2a in Appendix A in the SI SAP) to detect the presence of gamma radiation at 6 inch intervals. Each of the cores collected will be measured for radiological contamination and documented in the field. Measurements are to be documented in the field as to contamination depth, type, sampling location and quantity as well as the field screening measurements documented (EDi SOP 3B.5 and Appendix D). Measurements greater than 1.5 times instrument background for ambient air will be considered detections. Instrument background will be measured at the point of each measurement for ambient air. Samples will be screened for radiological contamination over the entire core collected at 6 inch intervals. If detected, samples for off-site radiological confirmatory analysis will be composited over the 6 inch area of the core detected with the highest radiological contamination. Samples for waste characterization will also be collected from the interval exhibiting the highest radiological contamination. However, if sufficient sample volume cannot be collected from that interval, the adjacent intervals may be composited to obtain the required volume such that the sample will be representative of media that may be encountered during future potential removal actions. Details on performing on-site radiological screening are presented in the SI SAP (USACE, 2003b). In addition, 20 percent of the overall number of

DACW41-01-D-0031 4-2 Site Investigation Work Plan PRAC DA02-9 Unnamed Tributary, Patroon Creek, and Three Mile Reservoir October 2003 Final Document Section 4.0 Field Activities samples, or a minimum of 5 samples, will be shipped to the off-site laboratory for confirmation sampling. The off-site laboratory will analyze the confirmation samples for radiological isotopes using gamma spectrometry and alpha spectrometry. The sample size and method tolerances will be considered during comparison between the alpha and gamma spectroscopy analysis. In addition, for all sample locations where an on-site Pancake Geiger-Mueller (PGM) instrument determines that radiological contamination is present, a split sample will be sent to the off-site laboratory and analyzed for Toxicity Characteristic Leaching Procedure (TCLP) metals. The waste characterization samples are to be collected from the same sample that is screened using a PGM instrument. Ten percent of these samples will be analyzed for full TCLP, ignitability, corrosivity as pH, and reactivity as confirmation. Due to the history of the area, TCLP metals is a target analysis of concern. However, to ensure that the IDM generated has been fully characterized, the full waste characterization suite will be being performed on 10% of the IDM collected. All analytical data collected will be validated by Shaw. Laboratory QC will be followed as described in the SI SAP (USACE, 2003b) and the Shell for Analytical Chemistry Requirements (USACE, 2001). This data will be included in the SI Report and used to further refine the CSM, if needed. 4.2.4 QA/QC Samples Rinse blanks will be acquired at a rate of at least 5% by sampling device (one for sediment sampling with a slam bar and one for the Vibracore sampler) and duplicates will be acquired at a rate of 10% by media (three sediment duplicates for radiological contamination for this sampling event). The analytical list for these samples appears as Exhibit 3-6 of the SAP (USACE, 2003b). In addition, one temperature blank will be included with each cooler shipped to the laboratory that contains samples to be analyzed for parameters requiring temperature preservation (Exhibit 2-3). 4.3 SEDIMENT SAMPLING PROCEDURES The sediment sampling procedures to be used for this field effort are described in this section. The field activities described herein will be performed in a manner consistent with the guidelines presented in the SI HASP (USACE, 2003c) to ensure worker safety. 4.3.1 Sediment Sample Acquisition Sediment samples from the upgradient locations, unnamed tributary, Patroon Creek,, and downgradient of Three Mile Reservoir will be acquired from each location using a decontaminated slam bar. Specific slam bar sampling protocols are contained in SOP S.5, located in Appendix A of the SI SAP (USACE, 2003b). From the Three Mile Reservoir, the sediment samples will be collected using a Vibracore sampler. Specific Vibracore sampling protocols are contained in SOP S.5, located in Appendix A of the SAP (USACE, 2003b). Capping and sealing of the core will be completed on the boat used for sample collection. Samples will be screened using a Pancake Geiger-Mueller detector [EDi SOP 5A.2 in SI SAP (USACE, 2003b)] for radiological contamination. Samples will be screened for radiological contamination over the entire core collected at 6 inch intervals. If detected, samples for off-site radiological confirmatory analysis will be composited over the 6 inch area of the core detected with the highest radiological contamination. Samples for waste characterization will also be collected from the interval exhibiting the highest radiological contamination. However, if sufficient sample volume cannot be collected from that interval, the adjacent intervals may be composited to obtain the required volume such that the sample will be representative of media that may be encountered during future potential removal actions. The radiological confirmation samples will be collected first, followed by the waste characterization samples. If a sediment sample comes back with less than 70% recovery, the sample location will be moved over roughly one foot and a replacement sample taken, unless there is a definite detectable radioactive signature on the first core.

Sampling depths in the upgradient locations, unnamed tributary, Patroon Creek, and downgradient of the Three Mile Reservoir will be a minimum of 6-12" below organic top layer to ensure the collection of a representable sample. Samples will be obtained with a slam bar and will be taken until the depth of refusal or a maximum depth of 3 ft, whichever occurs first. For sampling in the Three Mile Reservoir, the sampling depth will be a maximum of 9 feet and a minimum of 6.6 feet (2 meters). A continuous core through the layer of interest will be collected. Sediment

DACW41-01-D-0031 4-3 Site Investigation Work Plan PRAC DA02-9 Unnamed Tributary, Patroon Creek, and Three Mile Reservoir October 2003 Final Document Section 4.0 Field Activities borings in the Three Mile Reservoir will be advanced to the desired sampling depth using Vibracore methods to assess potential contaminant migration. To minimize the potential for cross contamination during sampling, sample CSD-US1, located upstream of the Colonie FUSRAP Site, will be collected first. The sampling sequence will than proceed from the downgradient-most location (sample CSD-DS2) incrementally upstream towards the site. Sample containers, as specified on Exhibit 2-3 of the SI SAP (USACE, 2003b), will be pre-labeled then, when filled, placed immediately in a cooler with ice. Each sample will be submitted to the contract laboratories for analysis using the methods specified in the SI SAP (USACE, 2003b). 4.3.2 Duplicate Sample Acquisition Three duplicate sediment samples are to be collected. One from the unnamed tributary, two from Patroon Creek, and one from Three Mile Reservoir will be acquired, as described in Section 5.2.4. The samples will be collected for the same parameters as the original samples. 4.3.3 Rinse Blank Sample Acquisition Two rinse blanks (one rinse blank sample from the slam bar and one from the Vibracore sampler) will be acquired in the field by pouring DIUF water over the decontaminated bar/sampler and into a decontaminated stainless steel bowl. Rinse blank acquisition procedures are presented as SOP S.8 found in Appendix B of the SI SAP (USACE, 2003b). The rinse blanks are to be analyzed off-site for radiological isotopes using gamma and alpha spectroscopy (Exhibit 4-2). 4.3.4 Sediment Location Surveying Sediment locations for the upgradient locations, Unnamed Tributary, Patroon Creek, Three Mile Reservoir, and downgradient of the Three Mile Reservoir will be marked using rebar at the point of sampling. At the discretion of the field team, buoys will be used if current conditions require their use. Locations will be surveyed as described in Section 4.2.2. 4.3.5 Decontamination Procedures Reusable sampling equipment is decontaminated by scraping off loose material, washing with an Alconox solution, and rinsing with distilled water in the field. Sampling equipment used to collect for metals and radioactive contaminants will be rinsed with a dilute nitric acid solution prior to the distilled water rinse. Decontamination rinse water will be containerized and treated as investigative derived waste (see Section 4.5.2). On-site laboratory decontamination rinse water and other de minimus quantities of aqueous waste are collected and treated using the groundwater treatment plant. Decontamination procedures are presented as SOPs D.1 and D.3 found in Appendix B of the SI SAP (USACE, 2003b). 4.4 INVESTIGATION-DERIVED MEDIA Sampling activities to be performed as part of this work plan will generate investigation-derived media (IDM). IDM includes extra sediments removed during sample collection. Uncontaminated IDM should not be considered a solid waste, if it will not be abandoned in an environmentally unsound manner, or is not inherently waste-like. To identify appropriate waste disposal facilities, there must be some initial waste characterization performed on the generated IDM. As per guidance contained in 40 CFR 261.2(a)(2), 10 CFR 20 Subpart C and D, and 6 NYECRR 380-5.1 (Exhibit 3-7), IDM must be handled as a solid waste when: • It is visually or grossly contaminated; • Elevated radiological readings are collected, indicating the presence of gamma emitters; • During USEPA monitoring/sampling activities, sediments exhibited levels of contamination above accepted environmental quality standards; and, • Based on historical information, the responsible party or the regulatory agency believes it warrants caution or additional testing. As with any solid waste, the generator must perform a hazardous waste determination. IDM with radiological contamination will be sampled for TCLP metals. In addition, ten percent of the samples will be

DACW41-01-D-0031 4-4 Site Investigation Work Plan PRAC DA02-9 Unnamed Tributary, Patroon Creek, and Three Mile Reservoir October 2003 Final Document Section 4.0 Field Activities analyzed for full TCLP and RCRA waste characteristics. The results from this testing will be used to determine the appropriate disposition of the materials. If the waste is not a hazardous waste, then that IDM may be disposed through any permitted or authorized waste management facility willing to accept the waste, in a manner permissible under law. Sediment IDM will be generated during sampling operations. All sediment IDM will be transported to the Colonie FUSRAP Site and placed on plastic or placed into a plastic lined drum. Drummed material will be appropriately labeled indicating the site ID, contents, dates generated, and the USACEE point of contact. These drums will be segregated/grouped according to radiological sample results and their defined study areas (e.g., sediment from the Patroon Creek or sediment exhibiting similar radiological readings or other physical characteristics will be grouped together). Upon completion of radiological sampling, all IDM will be transported to the Colonie FUSRAP Site and disposed with other radiological/mixed waste materials. 4.5 INVESTIGATION-DERIVED WASTE 4.5.1 PPE and Disposable Equipment Investigation-derived waste (IDW) will be generated from the use of PPE (gloves, etc.) during field investigation activities. This material will be stored in plastic garbage bags and disposed by Colonie FUSRAP Site with other radiological waste. 4.5.2 Decontamination Waters In the process of performing decontamination of sampling equipment, IDW consisting of decontamination water will be generated. The water generated will be drummed in 55-gallon drums and transported to the Colonie FUSRAP Site. The water will be placed in 55-gallon containers that will be transported to the Colonie FUSRAP Site and stored on pallets in a secure area, pending chemical analyses. Drummed water will be appropriately labeled indicating the site ID, contents, dates generated, and the USACE point of contact. These drums should be segregated/grouped according to radiological sample results and their defined study area. If the results of the drummed decontamination meet the Colonie plant disposal criteria, they will passed through the treatment plant for disposition. Else, they will be disposed of with the other radiological waste at the Colonie site.

EXPERIENCE AND BACKGROUND

1999 - Present Project Manager, Shaw/IT Corporation, Albany, New York Project manager for the final remediation of the Colonie New York FUSRAP site. This site is a six year, $55,000,000 USACE project involving mass excavation of radiological and RCRA hazardous waste materials from the former National Lead Industries complex. In this position he is responsible for a crew of 38 on-site personnel and for coordination with NYSDEC and multiple Corps Districts. Principal work includes construction and operation of a dewatering well field, on- site groundwater treatment system, on-site soil treatment/stabilization system and off-site shipment via rail for select materials.

TECHNICAL PROJECT PLANNING MINUTES FOR THE UNNAMED TRIBUTARY OF PATROON CREEK, PATROON CREEK, AND THREE MILE RESERVOIR, JULY 16, 2003

• Colonie FUSRAP Site Patroon Creek and 3 Mile Reservoir E3 TPP Meeting Albany, NY US Army Corps July 16, 2003 of Engineers®

A Technical Project Planning session was held for the Patroon Creek and 3 Mile Reservoir (3MR) on 16 July 2003. Attendees included representatives from the New York District, Baltimore District HTRW CX, NYSDEC, EPA, County of Albany Department of Health, and SUNY Albany.

Objective of the Meeting: Utilize a systematic planning process to design a data collection program that will properly define radiological impacts within the sediments of the unnamed tributary that crosses the National Lead (NL) site, a section of Patroon Creek between the unnamed tributary and 3MR, and the 3MR: - Fostering the Colonie Corps/Regulator/Stakeholder Execution Team relationships - Common understanding of site history and Conceptual Site model - Common understanding of overall site approach - Consensus on project objectives - Understand project constraints/dependencies - Understand regulator/stakeholder perspectives - - Consensus on data quality objectives

Overview of Site: Mitretek presented a PowerPoint presentation (attached) to provide all attendees a current reconnaissance of the creek. Shaw provided the site history of NL activities and site investigation in the area between the NL site and 3MR, as well as an overview of the construction of 1-90 and its impact to Patroon Creek and 3MR. In addition, an overview of the FUSRAP program and the US ACE cleanup authority was provided by NAB. (Handouts provided)

Regulator/Stakeholder Perspective: CSX: Current right-of-way agreement will need to be altered for this investigation work.

State of New York: State would like US ACE to investigate potential contamination of Patroon Creek based on work by Dr. John Arnason (i.e. a core sample in 3MR) that indicated a layer of uranium contaminated sediment. State would like us to consider public concern regarding the use of Patroon Creek and the reservoirs in it.

Future Land Use: Property currently owned by the CSX railroad, NYDOT, and the city of Albany. Plans for public use of the area along the creek and reservoir have been mentioned as a future wish of the community.

Project Goal: Page 1 of 5 Colonie FUSRAP Site Patroon Creek and 3 Mile Reservoir EBil TPP Meeting Albany, NY US Army Corps July 16, 2003 of Engineers®

Obtain sufficient data to enable DOE to make a decision whether the unnamed tributary, Patroon Creek, and 3MR should be included as a vicinity property of the Colonie FUSRAP site, as a result of NL operations that may have allowed radioactive contamination to migrate from the Colonie FUSRAP site.

Regulatory Framework: Work at this site is being accomplished under CERCLA. On the Colonie Site, the government, as owner of the site, was responsible for remediation of all contaminants. The government's responsibility on the vicinity properties is only for the radioactive contamination. Any other contamination will be evaluated for disposal and worker safety purposes. Since Patroon Creek has not been named as a vicinity property, this investigation will be an enhanced Site Inspection with the key objective of this project phase being to determine absence/presence of radioactive contamination.

Project Objectives: - Determine absence/presence of radioactive contamination as a result of NL operations that may have allowed radioactive contamination to migrate from the Colonie FUSRAP site. Begin to define the extent of radioactive contamination in 3MR indicated by the results detected at one sampling location to date. Concentrations, distributions and location data were determined as follows: - Locations include: o Upstream of Colonie Site, as a result of airborne release in Patroon Creek upstream watershed o Unnamed tributary that crosses the Colonie site o Patroon Creek from the unnamed tributary to 3MR o 3MR o Immediately downstream of 3MR

For waste acceptance criteria, determine the level of metals contamination in the radioactive contaminated sediment areas. This data will be used for order-of-magnitude estimation of potential remedial actions. (No VOC or semi-VOC analysis)

- For worker health and safety requirements, determine the level of non-radiological contamination in the radioactive contaminated sediment areas. This will be used to verify current worker safety procedures and for order of magnitude estimation of potential remedial actions. o Note: Sampling for non-radiological constituents will be at detection limits that support the above objectives and not at levels to support a human health risk assessment.

- Perform a streamlined risk evaluation to assist in the determination of whether the Patroon Creek area should be designated a vicinity property. A vicinity property designation will be needed if further characterization is required to conduct an RI/FS phase. If the need for remediation is likely, provide an order-of-magnitude cost estimate Page 2 of5 Colonie FUSRAP Site Patroon Creek and 3 Mile Reservoir TPP Meeting

US Army Corps T?T^ of Engineers" My 16,2003

of potential remediation costs.

o Note: The streamlined risk evaluation will use NRC/EPA screening numbers, even though they are for surface contamination. A site-specific risk evaluation is not appropriate at this time, as the exposure pathway determinations have not been made.

- Respond to public concerns of recreation/trespasser use of Patroon Creek and 3MR, which include use of surface water and sediments downstream of 3MR.

Data Needs: Location/Number of Samples: Depends on exposure units for current/future use and statistics. Creek sampling point will be field adjusted to obtain samples only where sediments have been deposited. However, we realize that these represent current creek conditions amd not past sediment transport conditions. Please refer to handout showing proposed sampling point locations. Discussions have led to the following sampling locations, which are referred to by the numbers shown on the "Expanded Site Map": Unnamed tributary: Locations represent surface water transport mechanism. - Transects "1/2/3"; and "5/6/7", Transects are included to represent cross- section of creek to account for various flow/sedimentation conditions. Waste from the Colonie site was used as backfill for Patroon Lake, which was located on the unnamed tributary. - Sample point "4".

Patroon Creek: - An upstream sample point at location "SD-4" (previous sampling location) to represent possible airborne release and transport - Sample point "8" -Sample point "13", - In the sedimentation pool before Central Avenue, - One sample point between Central Avenue and 3MR (around sample points "20" or "21")

3 Mile Reservoir: 15 sampling points for statistical purposes -see enclosed photo with transect and longitude sampling points. The old sedimentation basin may have started about sample point "21". - Transect locations are near dam as that is where the previous core sample showed contamination, at the beginning of transition section between creek and 3 MR where the old sedimentation basis was location and where the wetlands begin, and two transects mid point between. Single sampling points are located between transects along a path of the main flow. Transects and individual points should give us a very good picture of the extent of contamination. Note: Much finer grained sediments exist adjacent to the dam with the sandier material dropping out at the upper end of the 3MR. Uranium can be in the form of a Page 3 of .5 Colonie FUSRAP Site Patroon Creek and 3 Mile Reservoir TPP Meeting Albany, NY US Army Corps July 16,2003 of Engineers®

particle size adsorbed to clay or individual particles.

Downstream of 3MR: Two sample points in areas of sedimentation to determine if material has moved downstream of 3MR and to alleviate public concern. State suggests getting input from Arbor Hill group on sampling locations.

Depths: Sampling depths in the unnamed tributary and creek will be a minimum of 6- 12" below sedimentation layer to ensure the collection of adequate sample mass. Samples will be obtained with a "slam bar" and will be taken until the depth of refusal. In 3MR, core will be 9 foot maximum, and 2-meter minimum. Continuous core through layer of interest is desirable. Anticipate capping and sealing core on boat.

Analytical sampling: Gamma Spec will be used for determining concentrations of radiological contamination to be used in the risk assessment, with a method detection limit of IpCi/gm. Alpha spec will be used to confirm depleted uranium on 10% of the samples. Cores in 3MR will be screened, and 1-2 samples per core will be tested based on the highest radiological readings within a 6 inch sample interval. Discuss in all documents that the gamma spec and the alpha spec numbers are not identical and that the gamma spec is skewed on the high side. QA/QC will be done for 20% of the overall number of samples, or a 5 sample minimum. This will consist of offsite gamma spec and alpha spec. State also wants QA/QC samples.

Site Information Needs:

Information on over bank flooding would be useful in the future if designated vicinity property. This may provide additional information on extent, but is not needed for this enhanced SI phase. Dr. Arnason's data indicated that cadmium exhibited concentration trends similar to the elemental uranium. Processes conducted at the NL plant included an electroplating operation for plating uranium with nickel and cadmium. Historical information from the NRC indicates that some of the electroplating was performed to support depleted uranium ballast for the Boeing 747 aircraft. Cadmium was identified within small areas of the Colonie Site. However, due to the small areas of contamination present, all the material will be removed with the associated uranium and lead removal. The 1989 DEC report would provide additional information on previous sampling in Patroon Creek and may help us locate our new samples in the best places to match up to existing data. Monitoring wells located in Patroon Creek before 3MR have not been identified. Need to find owner, and what data may be available.

Constraints and Dependencies:

Real estate access is needed from CSX, State DOT and City of Albany. Permits may be required to work in the stream bed (state) or wetlands. Proposed raising of water levels in 3MR may contribute to dam instability issues and may Page 4 of 5 Colonie FUSRAP Site Patroon Creek and 3 Mile Reservoir TPP Meeting Albany, NY US Army Corps July 16,2003 of Engineers® impact the need for permit(s) if the stream bed or wetland areas may be impacted. Winter conditions will prevent fieldwork due to icy dangerous conditions. Work should be completed in fall or spring. November 1 is the anticipated cutoff for fall work.

Schedule:

Workplan will be ready in mid-August. Concurrent review by US ACE, NYSDEC, and HTRW CX with a conference call to discuss comments. (Review time should be relatively short because of the details discussed in this TPP meeting.) Information meeting should be held with public prior to starting fieldwork. Fieldwork should take about 3 weeks to execute. Work will be funded with FY04 funding so that a fall start date would be no earlier than 6 October but probably 13 October.

Closing/Action items:

NYSDEC will help located 1989 document (Barb) Shaw will help with revised access agreements with CSX and NYDOT Monitoring wells located in Patroon creek, need to find out whose they are. DEC permit requirements: should be exempt but still must fulfill requirements. Barb will coordinate with other DEC departments for wetlands and streambed. Meeting minute notes will be distributed to all. Additions/corrections are welcome. Meeting minutes will serve as basis for workplan. Get an example of a report approved by DOE that was used to add a new vicinity property.

Meeting was conducted in an open manner, with great discussion among all.
