The Site is located in the Upper Hudson River from Fort Edward, New York to the Federal Dam in Troy, New York (Figure 1-1). The OM&M activities involved sediment and fish sampling within eight river reaches, sample analysis, data evaluation, and reporting. The field and analytical work were conducted in accordance with the Letter Work Plan for the Hudson River PCB Sediments OU-2 Site (546031) (EA 2017a), EA’s Generic Field Activities Plan (2011a), and the NYSDEC Division of Environmental Remediation (DER)-10 Technical Guidance for Site Investigation and Remediation (NYSDEC 2010). 1.1 SCOPE AND OBJECTIVES 1.1.1 Project Objectives The primary objectives of the OM&M activities included: • Undertake post-remedial sediment monitoring to evaluate the performance of the U.S. Environmental Protection Agency (EPA)-lead Hudson River PCB Sediments Site dredging and monitored natural recovery remedy. • Collect data points sufficient to achieve defined statistical objectives. • Establish baseline post-dredging concentrations of PCBs in the Upper Hudson River to use as comparison points in determining estimated sediment recovery rates. 1.1.2 Report Objectives This Data Summary Report summarizes the field, laboratory, data validation, data handling, and statistical methods employed during the OM&M activities; as well as the findings from the field investigation, including data tables, figures, and data interpretation. The overall objective of this report is to present and evaluate the final validated data collected from the Site during the 2017 OM&M activities. 1.2 SITE DESCRIPTION The Hudson River PCB Sediments Site (EPA Identification Number NYD980763841) includes a nearly 200-river-mile stretch of the Hudson River in eastern New York State from the Village of Hudson Falls to the Battery in New York City. For evaluation purposes, the river was divided into the Upper Hudson River (the length of river between the Village of Hudson Falls and the Federal Dam at Troy, New York) and the Lower Hudson River (the length of river between the Federal Dam at Troy, New York, and the Battery). The subject Site for this field program is the Upper Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 1-2 December 2018 Hudson River; a 40-mile stretch of the river from the town of Fort Edward, New York, to the Federal Dam in Troy, New York (Figure 1-1). The EPA further divided the Upper Hudson River area into three main sections: River Section 1 is the most upstream section, extending approximately 6 miles from Fort Edward to the Thompson Island Dam; River Section 2 extends from the Thompson Island Dam to the Northumberland Dam near Schuylerville, an extent of approximately 5 miles; and River Section 3 extends from below the Northumberland Dam to the Federal Dam at Troy, an extent of approximately 29 miles. The Hudson River PCB Sediments Site is broken into four OUs defined by EPA: OU-1 is the remedial work performed under the 1984 Record of Decision (ROD), OU-2 is the remedial work performed under the 2002 ROD, OU-3 is the removal action performed on Rogers Island in 1999, and OU-4 is the ongoing remedial investigation in the floodplains (NYSDEC 2016). The Upper Hudson River is both freshwater and non-tidal, with several tributaries joining downstream of Fort Edward. The largest of those tributaries are the Mohawk River, Batten Kill, Fish Creek, and the Hoosic River. Flow in this stretch of the Hudson River is primarily controlled by reservoirs above Glens Falls, including the Great Sacandaga Lake. The Upper Hudson River has an average depth of approximately 18 feet (ft) in the channel and less than 8 ft in the shoals, with a maximum depth of more than 45 ft. In the project area, the New York State Canal Corporation (NYSCC) navigation channel is generally identified as being a minimum of 12 ft deep (NYSDEC 2016). Land use surrounding the Upper Hudson River consists primarily of residential and agricultural uses, with some commercial and industrial. The upper stretch of the Hudson River flows through four counties (Albany, Washington, Rensselaer, and Saratoga), where predominant landscapes include forests and farmlands surrounding urban centers and historic villages. Adjacent to the Upper Hudson River, ecosystems generally include forested shoreline wetlands, transitional uplands, and vegetated backwater such as emergent marsh and scrub-shrub wetlands. In terms of commerce and industry in the area, counties along the Upper Hudson River are home to technology, oil service, and food companies, as well as the General Electric (GE) Hudson Falls and Fort Edward plants. 1.3 SITE HISTORY Throughout an approximate 30-year period ending in 1977, GE used PCBs in its capacitor manufacturing operations at its Hudson Falls and Fort Edward, New York facilities. During this time, PCB oils were discharged both directly and indirectly from these plants into the Hudson River. New York State began an enforcement action against GE in the early 1970s, resulting in limitation of the direct PCB discharges from the capacitor plants and construction/operation of a new wastewater treatment plant at the Fort Edwards facility. In 1973, the Fort Edward Dam, a short distance downstream of the GE capacitor plants, was removed. Because of this removal, PCB-laden sediments once captured behind the dam were remobilized and deposited downstream, primarily near Rogers Island. In 1975, the New York State Department of Health (NYSDOH) issued the first consumption advisories for fish from the Hudson River, advisories that exist to the present day. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 1-3 December 2018 In 1984, the 200-mile stretch of river between Hudson Falls and the Battery in New York City, was placed on EPA’s National Priorities List (NPL) of the country’s most contaminated hazardous waste sites. EPA completed a Feasibility Study (FS) in 1984 and issued a ROD for the site, identifying contamination in the Upper Hudson River sediments as a threat to human health and the environment, but selected an interim No Action remedy for the contaminated sediments due to uncertainty in the reliability and effectiveness of remedial technologies available at that time. Both New York State and the federal government continued to evaluate water quality, sediment, air quality, fish, and wildlife. Studies demonstrated that the river was not naturally recovering, and PCBs in the sediment posed a serious risk to human health and the environment. Investigations conducted to evaluate the extent of the problem revealed that most of the contaminated sediments were in “hot spots” situated in a 40-mile stretch of the river between the Town of Fort Edward and the Federal Dam. In December 1989, EPA announced its decision to initiate a detailed Reassessment of the Interim No Action decision for the Upper Hudson River sediments. This was prompted by the Five-Year Review required by Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), technical advances in sediment dredging and treatment/destruction technologies, as well as a request by NYSDEC for a re-examination of the 1984 ROD. EPA completed the Reassessment in December 2000, with the release of the FS and Proposed Plan in late 2000. The Reassessment work is documented in several reports summarizing investigations conducted between 1991 and 2000. The Reassessment work culminated in the issuance of another ROD in 2002, which provided for the dredging of select sediment in the Upper Hudson River, and the establishment of performance standards to govern implementation of the project. 1.4 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIONS Baseline water quality and fish data were collected, and engineering designs for the dredging remedy were completed and approved in 2008. During the design phase, a new water transmission pipeline was built to protect downstream water supplies from potential impact from the dredging work. Phase 1 of the dredging project was performed in 2009. Monitoring and operational data collected during Phase 1 indicated that PCB contamination extended deeper than anticipated and dredging plans were adjusted to optimize removal. At the end of Phase 1, a total of 286,000 cubic yards (cy) of contaminated sediment were removed from 48 acres of river bottom (NYSDEC 2016). In 2010, EPA performed a Peer Review of the environmental monitoring and operational data and issued modifications to the scope of work and performance standards. EPA completed the first Five-Year Review in 2012. Based on the monitoring and operational data collected during Phase I, the Five-Year Review concluded that the fish flesh PCB goals would not be met in the targeted timeframe. Between 2011 and 2015, approximately 2.4 million cubic yards of contaminated sediment were removed. Habitat reconstruction was completed and facility decommissioning was performed in 2016. The required post-remediation EPA-lead OM&M activities described in the Phase 2 Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 1-4 December 2018 OM&M Scope included monitoring of the sediment caps and stabilization measures installed in certain dredged areas and of the habitat replacement/reconstruction implemented in various areas of the Upper Hudson River (EPA 2010). The OM&M activities also included long-term water column, fish, and sediment monitoring to assess recovery. GE conducted the first year of one component of the EPA-lead OM&M sediment sampling program in the Fall of 2016, and collected data to establish baseline post-dredging PCB concentrations for use as a point of comparison. EPA specified the collection of 226 surface sediment samples in non-dredged areas. The specific surface sediment sample locations were selected by EPA, using a randomized, unbiased sampling design. In addition, EPA provided a full set of 226 backup locations in case the primary locations were inaccessible or did not have sufficient sediment for sampling. A grab sampler was used to collect sediment samples from 192 of the primary target locations and 23 backup locations, for a total of 215 locations in non-dredged areas (Anchor QEA, LLC [Anchor] and Environmental Standards, Inc. [ESI] 2017). Samples were not collected at 11 locations because of lack of boat access or abandonment due to insufficient sediment. GE completed the second component of the first year of the EPA-lead OM&M sediment sampling program, conducting sampling inside dredged areas (126 locations anticipated, 149 samples – 15% quality assurance [QA] samples), in the Fall of 2017. EPA has not yet approved long-term monitoring plans for OU-2 (Anchor and ESI 2016). Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-1 December 2018 OPERATION, MAINTENANCE, AND MONITORING FIELD ACTIVITIES The specific objectives for the OM&M activities performed in 2017 by NYSDEC were to: (1) undertake post-remedial sediment monitoring to evaluate the performance of the EPA-lead Hudson River PCB Sediments Site dredging and monitored natural recovery remedy, (2) collect data points sufficient to achieve defined statistical objectives, and (3) establish baseline post-dredging concentrations of PCBs in the Upper Hudson River to use as comparison points in determining estimated sediment recovery rates. OM&M field activities were conducted from 15 June 2017 to 19 September 2017 and consisted of sediment sampling and fish sampling within eight river reaches (Figure 1-1). Field OM&M activities were conducted in accordance with the NYSDECapproved OM&M Letter Work Plan (EA 2017a) and the OM&M Letter Work Plan Addendum– Fish Sampling (EA 2017b), with the exception of deviations identified in Section 2.4. Field OM&M activities and sampling procedures were conducted in a manner consistent with the EA Generic Health and Safety Plan (EA 2011b), Generic Field Activities Plan (EA 2011a), and Generic Quality Assurance Project Plan (QAPP) (EA 2011c) developed for Work Assignments conducted under Standby Engineering Services Contract Number (No.) D007624, and the associated site-specific addenda. Field modifications from the Work Plan (EA 2017a, 2017b) sampling procedures were approved by NYSDEC. 2.1 SAMPLING PROGRAM OVERVIEW The sampling program was conducted in two phases. The first phase consisted of sediment sampling activities, and the second phase consisted of a fish sampling effort. Sediment sampling was conducted from 15 June 2017 to 31 August 2017. Three sampling vessels operated 6 days per week, targeting 1,678 locations and collecting 1,156 surface samples for laboratory analysis (457 locations were abandoned and 65 locations were removed from the program due to inaccessibility and/or safety concerns). At the request of NYSDEC, EA added the fish sampling effort to support NYSDEC’s long-term monitoring objectives. Fish sampling began on 11 September 2017 and continued through 18 September 2017; final fish sample processing and shipping occurred on 19 September 2017. One vessel operated daily, collecting a total of 232 fish samples for laboratory analysis. For the purposes of this OM&M field effort, NYSDEC broke the Upper Hudson River into eight reaches, or pools, instead of the three river segments as defined by the EPA. The river reaches generally correspond to portions of the river behind locks and dams, and NYSDEC expects the defined reaches to better relate to patterns of PCB fate and transport than the broader groupings defined by the river sections. The reaches were defined, moving north to south along the river, as the following: • Reach 8: Thompson Island Dam to the Fort Edward Dam/Rogers Island (Thompson Island Pool) • Reach 7: Lock 6 to the Thompson Island Dam (Fort Miller Pool or Landlocked Pool) Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology 2.2 EA Project No. 14907.36 Version: FINAL Page 2-2 December 2018 • Reach 6: Lock 5 to Lock 6 in Fort Miller (Northumberland Pool) • Reach 5: Lock 4 to Lock 5 in Schuylerville/Northumberland (Stillwater Pool) • Reach 4: Lock 3 to Lock 4 in Stillwater (Upper Mechanicville Pool) • Reach 3: Lock 2 to Lock 3 in Mechanicville (Lower Mechanicville Pool) • Reach 2: Lock 1 to Lock 2 in Mechanicville • Reach 1: Federal Dam at Troy to Lock 1. SEDIMENT SAMPLING Three primary vessels were utilized concurrently during the majority of the sediment sampling field effort. EA provided two vessels: the research vessel (R/V) Belle, a 28-ft SeaArk, and the R/V Jane B, a 25-ft SAFE boat. Athena Technologies, Inc. (Athena) provided the third vessel, the R/V Good Vibrations, a 24-ft pontoon boat. In areas of insufficient water depth for safe vessel operation, EA’s 17-ft shallow draft Jon boat, the R/V Shocker, was used. The R/V Shocker was staffed with a two-person field crew. The R/V Belle and the R/V Jane B were each staffed with a three-person field crew consisting of a boat captain and two deck hands. The R/V Good Vibrations was staffed with two Athena field team members, a boat captain and a deck hand, and an EA field team member who performed oversight and assisted with sample collection and logging. Mobilization for the sediment sampling field effort commenced on 12 June 2017. On 15 June 2017, sampling commenced on the R/V Belle, which was used for sediment sampling until 19 August 2017. The R/V Jane B was in operation from 17 June 2017 to 30 August 2017, and the R/V Good Vibrations was in operation from 6 July 2017 to 30 August 2017. The R/V Shocker was in operation from 22 August 2017 to 30 August 2017. Deviations to the work schedule are detailed in Section 2.4.2. A second, 17-ft shallow draft smaller Jon boat was used on 31 August 2017 to collect surface and subsurface sediment samples from the old Champlain Canal area in Schuylerville, New York; details are included in Sections 2.4.1 and 2.4.2. Surface sediment samples were collected in both non-dredged and dredged areas of the Upper Hudson River (Figures 2-1A through 2-1D). At each location, a surficial sample was collected (via modified Van Veen sampler; exceptions detailed in Section 2.4.2) to characterize surface sediments. Sample location coordinates, sediment elevation, and bathymetric survey data were also collected. The number and location of target sample locations was selected to provide sufficient data points to achieve defined statistical objectives (Sections 2.2.1 and 4). Sample sizes for each reach established in the study area were selected based on statistical evaluation of existing data. Sample locations were selected using a randomized and unbiased sampling design; additional information on the sample number and location selection rationale is included in Section 2.2.1. The coordinates Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-3 December 2018 for each target location and associated field notes are provided in Tables 2-1A–H. Sample collection methods were generally consistent with those specified in the Surface Sediment Sampling Work Plan for 2016, Hudson River PCBs Superfund Site (Anchor and ESI 2016). Additional information on sample collection methods is included in Section 2.2.3. A global positioning system (GPS) survey of all investigation/sampling locations was completed as part of the sediment collection effort. Survey data were collected electronically from the navigation system and fathometer on each sampling vessel. Additional details on the survey data collection are provided in Section 2.2.3. Laboratory analyses were performed by Pace Analytical Services, LLC (Pace) at their laboratories in Minneapolis, Minnesota; Green Bay, Wisconsin; and Billings, Montana. Surface sediment samples were analyzed for PCB Aroclors, PCB congeners, grain size, moisture content, and total organic carbon (TOC). Analytical testing methods were carried out in accordance with procedures outlined in the Generic QAPP (EA 2011c), Work Plan (EA 2017a), and site-specific QAPP addendum (EA 2017c), with the exception of moisture content; details are included in Section 2.4.2. Field modifications from the QAPP sampling procedures were approved by NYSDEC. Environmental Data Services, Inc. (EDS), an independent third-party data validator, reviewed analytical data provided by the analytical laboratory. EDS completed a 100% Category A and 20% Category B data validation. 2.2.1 Sediment Sampling Program Design and Rationale The number of samples sufficient to achieve defined statistical objectives was determined using statistical design objectives specified by NYSDEC. The specific statistical design objectives included: (1) the ability to detect an 8% annual decline in mean sediment total PCB concentrations within a given reach between two consecutive 5-year monitoring periods with a statistical power of 80% at the 95% confidence level, and (2) the ability to determine the arithmetic mean PCB concentration for each reach with a relative error no greater than 20%. An analysis of both the Sediment Sampling and Analysis Program (SSAP) historical data (2003–2005), and the recent EPA/GE (2016) sample data in the non-dredged areas was conducted in order to estimate baseline arithmetic means and standard deviations for each river reach (Anchor and ESI 2002, 2016). Statistical analysis indicated that a sample size of 1,791 would satisfy these objectives. Since future data analysis was expected to combine the results of sampling from the EPA/GE 2016 data set with NYSDEC data, the 215 samples collected by EPA/GE in 2016 was subtracted from the sample size, yielding a total recommended sample number of 1,576. Based on discussions with NYSDEC, 13 additional locations were added to target areas of interest. A sample number of 1,589 was selected for the baseline sediment monitoring event to provide a robust initial data set to support future analysis. An additional 84 samples were added to the field sampling plan in other areas that were identified as potentially difficult to access due to water depths or safety concerns around the lock and dam structures, for a total of 1,673 targeted samples. Sample locations were selected using a randomized and unbiased sampling design, using a systematic triangular grid with a random start location. The grid used to designate sample locations excluded bedrock, areas close to the locks deemed to be unsafe for sampling, and locations sampled by EPA/GE in 2016.

The new locations were added to an alcove in Schuylerville, New York, that had not been included in the ArcGIS shapefiles used in the statistical analysis and sampling design. On 27 June 2017, the R/V Jane B collected samples from locations at the mouth of alcove, and upon realizing the alcove was navigable, notified NYSDEC about the possibility of collecting additional samples from further up the alcove. Upon request from NYSDEC, EA added 5 locations spanning the length of the alcove, bringing the total number of target sample locations to 1,678. Sample collection protocols, decontamination protocols, analytical methods, and data management procedures specified in the Surface Sediment Sampling Work Plan for 2016, Hudson River PCBs Superfund Site (Anchor and ESI 2016) were utilized in this sampling event, with alterations noted in the 2017 Work Plan (EA 2017a). These methods were selected to facilitate data comparisons and to allow data collected in the separate sampling events to supplement each other. 2.2.2 Precision Navigation and Horizontal Control Global Navigation Satellite System (GNSS) survey techniques were used to navigate the R/Vs to within 10 ft of the target sample locations. GNSS utilizes data from both the United States (GPS) and Russian (GLONASS) satellite networks, yielding superior positional accuracy in the horizontal and vertical planes. All horizontal measurements collected were referenced to the New York State Plane East Coordinate system, U.S. Survey Feet and in the North American Datum of 1983 (NAD 83), while the vertical observations were referenced to the North American Vertical Datum of 1988 (NAVD 88). Differential corrections for the satellite positioning data were received real-time through a subscription to the KeyNetGPS Virtual Reference Station (VRS) Network (http://www.keynetgps.com). KeyNetGPS provides information derived from the National Geodetic Survey (NGS) Continuously Operating Reference Station Network. The validity of the VRS correctors and positional information was verified via cross-check comparisons at a NGS benchmark located in Fort Miller (GPS and vertical control location AA7911). The benchmark was occupied at the start of the field effort and periodically throughout the duration of the effort as a QC check to ensure the continued accuracy of the information being utilized. Vessel Navigation Precision positioning for the sediment sampling operation was provided by a roving Trimble R8 GNSS receiver onboard the R/V Belle and a roving Trimble SPS 461 GNSS receiver onboard the R/V Jane B. Positioning information onboard the R/V Good Vibrations was provided by a Champion TKO GNSS receiver. All units simultaneously utilized GPS and GLONASS satellites to independently resolve the position of the antenna at an accuracy of ±3 meters at a rate of up to 10 hertz in autonomous (or standalone) mode. Following the application of the VRS corrections, the positional information generated by the roving Trimble R8/Trimble SPS 461/Champion TKO GNSS receiver units yielded positional fixes with geodetic accuracies of 2 centimeters (cm) in the horizontal plane and 5 cm in the vertical plane. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-5 December 2018 The positioning information acquired by the roving Trimble R8/Trimble SPS 461/Champion TKO GNSS units was ported directly to HYPACK navigation and data acquisition software running on a computer laptop onboard the vessels via serial connection. HYPACK served as the primary survey management system; logging time, geographic position, and depth data continuously. It also provided a helmsman display, allowing the vessel operator to maneuver the vessel with the 100 ft radius surrounding the target sample location. The data were transmitted as National Marine Electronics Association strings (i.e., GGA – position and accuracy, heading in degrees true, and ZDA – GPS time reference in Zulu Time or Universal Time Coordinated) providing time, position and vessel heading, and elevation. As the data were received in HYPACK, the geodetic coordinates were converted to New York State Plane East coordinates in the units of U.S. Survey Feet in real time, based on the horizontal datum of NAD 83. The ellipsoidal height information was passed through the Continental United States 2012A Geoid model that converted the information to elevation (orthometric height) tied to the vertical datum of NAVD 88 in real time. 2.2.3 Sediment Sample Collection The R/Vs navigated to the target sample locations utilizing HYPACK software. Once in position, field personnel deployed spuds and/or anchors, if appropriate. If a sampling location was in an area where using spuds or anchors was not feasible or if live-boating was preferable due to river conditions, sample collection without anchoring was attempted, and the vessel operator maintained position by making small adjustments. Live-boating facilitated field crew adjustment of a sample location when poor recovery warranted attempting additional grab samples. At locations where water depths were less than 20 ft, a 0.5-inch (in.) diameter steel rod marked in 6-in. intervals (or equivalent) was used to manually probe the sediment surface to determine the surficial sediment type. The estimated sediment type (e.g. rock, fine-grained, coarse-grained, etc.) was recorded in the logbook and electronic field form. Samples were collected using a modified Van Veen (Van Veen sampler modified with a supporting frame) capable of sampling in a variety of sediment conditions. In the event that use of a modified Van Veen sampler was not feasible or safe, samples were collected with a ponar dredge sampler or a Van Veen sampler; deviations from the sampling protocol are provided in Section 2.4.2. A total of 1,082 surface sediment samples (excluding quality control [QC] samples) were successfully collected using a modified Van Veen sampler, 48 samples were collected using a ponar dredge sampler, and 26 samples were collected using a Van Veen sampler. The procedure for collecting surface samples via modified Van Veen included deploying the sampler off the edge of the boat, retrieving the sampler to the boat deck, and assessing whether the grab was usable (i.e., jaws were fully closed, no sediment runoff, washout noted, etc.). If the grab was usable, water was gently decanted from the top of the sampler using a clean siphon and the top 2 in. of sediment was transferred to an appropriate pan (typical penetration depths with the modified Van Veen sampler were 6 in.). The top 2 in. of sediment were determined using a spoon with a hole drilled at the 2-in. mark. Sediment was thoroughly homogenized and transferred to laboratory-approved containers, labeled, and stored on ice. All non-dedicated sampling equipment and tools used during sample collection were decontaminated using river water, a brush, and a Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-6 December 2018 deionized water spray, in accordance with the Work Plan (EA 2017a). Remaining sample volume was returned to the river after sample collection at that location was complete. The same procedure was used for collecting surface samples via ponar dredge and via Van Veen. Equipment blanks were prepared in the field by processing a sample of playground sand in the same manner that environmental samples were processed. If the grab was not usable, or was usable but did not contain sufficient material for sample collection, procedures for collecting additional grabs, compositing grabs, and abandoning locations were conducted in accordance with the Work Plan (EA 2017a). Starting on or near the proposed target sample location, the field crew attempted 3 grabs. If a sample, or sufficient sample volume could not be collected from those 3 grabs (composited, if necessary), the boat was repositioned to a different location within a 100-ft radius of the target sample location. In order to achieve sufficient volume for filling all required sample, the top 2 in. of sediment from grab sample attempts 1 through 3 or attempts 4 through 6 could be composited. The samples were combined into one aluminum pan and homogenized thoroughly prior to collection. In all, 43 of the over 1,200 samples were composites of 2 or 3 grabs. Alternate locations within the 100 ft was chosen using several lines of evidence, including: visual observations of the attempted grabs (e.g., were soft sediments present and washed out, or were only cobbles pulled up in the sampler), known channels in the river (i.e., if target location was in a channel and the first 3 attempts were unsuccessful, the next attempts targeted an area outside of the channel), visual observations of depositional areas and/or bank composition, probing data, and transducer readings. Three or more additional grabs were attempted at an alternate location within the 100-ft radius. After a minimum of 6 unsuccessful attempts, the location was abandoned. Minor derivations from this approach were implemented when samples were collected via a smaller, flat bottom boat in water depths shallower than 1 ft that required the vessel to be run aground in order to sample within the 100-ft sampling radius. In these instances, one positional fix was used to represent the first 3 sampling attempts. If unsuccessful, a new location within the 100-ft radius was then occupied, a single positional fix obtained, and 3 or more additional attempts to recover sediments made. If a sample was successfully collected in these conditions, a positional fix was taken directly over the sampling location. In accordance with the Work Plan, coordinates were recorded at each (EA 2017a) location where a sample was retained. The field team also recorded the number of sampling attempts deemed valid/fully compliant with project requirements at each location on field log sheets and the conditions encountered during each attempt. While not specified in the Work Plan, coordinates were recorded in raw data files each time the grab sampler was deployed and contacted the bottom. Thus, raw data files contain a series of coordinates at each of the over 1,600 locations visited. Coordinates in the raw data files represent: sampled locations, locations where samples were not collected due to refusal, materials (cobble, debris, shells, submerged aquatic vegetation) stuck in the sampler jaws, additional material to satisfy QA/QC (field duplicates and matrix spike/matrix spike duplicate) requirements, exploratory grabs in cobble-gravel transitional areas, instances where the field team was collecting toward the edge of the 100-ft radius and the sampler set down outside of the station radius. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-7 December 2018 Field data and observations of the sediment and sample location were recorded during the sample collection process. The actual coordinates and water depth of the sample location were collected when the sampler hit the bottom of the river, and recorded electronically and in the field logbook, as well as in HYPACK. Water depth was continuously measured in real time by the fathometer; exceptions are described in Section 2.4.2. Water surface elevation was also collected at the time the sampler hit the bottom of the river, using the roving Trimble R8/Trimble SPS 461/Champion TKO GNSS units. Sediment surface elevation was calculated and recorded in the field log and sample field forms. The sample naming convention included the general project area and year collected as the first field (HR17-OU2 stands for Hudson River 2017, OU-2). The second and third fields in each sample name indicates the reach number, identified as R1, R2, R3, R4, R5, R6, R7, or R8, followed by the 3-digit number associated with the sample location. Field duplicates, equipment blanks, method blanks, and performance evaluation (PE) samples followed the naming scheme established for the native samples, using HR17-OU2, followed by the reach, QA/QC sample type (field duplicate/equipment blank/performance evaluation), and QA/QC sample number, which was assigned consecutively within each reach. Water Depth Data Acquisition An ODOM Echotrac CVM single-beam survey fathometer interfaced with a dual frequency (200 and 24 kilohertz) transducer was used to collect depth soundings at each location to a resolution of 0.1 ft. The transducer was pole-mounted to the starboard side of the EA and Athena vessels and at a fixed depth below the water’s surface (draft). A draft correction was applied to the soundings by the fathometer to reflect the actual water depth relative to the air-water interface versus the bottom of the transducer. The raw depth soundings obtained by the ODOM Echotrac CVM were ported directly to HYPACK, where they were time-tagged and merged with positioning information. These data were then stored for post-processing and analysis at the conclusion of the field effort. The functionality and performance of the fathometer was verified via a series of lead line measurements at the start of each sampling day to ensure the accuracy of the recorded depth readings. 2.2.4 Analytical Program Analytical samples were submitted to Pace laboratories located in Minneapolis, Minnesota; Green Bay, Wisconsin; and Billings, Montana. Samples were analyzed for PCB Aroclors and PCB congeners at the Minneapolis laboratory; TOC at the Green Bay laboratory; and grain size and moisture content at the Billings laboratory. Samples collected from 10 August 2017 to the end of the sampling event, were also analyzed for moisture content by American Society for Testing and Materials (ASTM) method D2216 at Atlantic Testing Laboratories in Clifton Park, New York. Deviations from the analytical protocol are included in Section 2.4.2. Sediment samples at each location were analyzed for the following: PCB Aroclors, TOC, grain size, and percent moisture. Samples from 10 percent of the sample locations were analyzed for PCB congeners. Locations for PCB congener analysis were randomly selected and spaced Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-8 December 2018 throughout the reaches. Sample analysis was completed as planned in the Generic QAPP (EA 2011c) and site-specific QAPP addendum (EA 2017c), with exceptions noted in Section 2.4.2. 2.2.5 Sample Handling, Chain-of-Custody, and Documentation Each vessel, the onshore field coordinator, and the sample manager maintained separate logbooks. Copies of field logbooks are included in Appendix A. Surface sediment sample collection data were recorded in the electronic field data forms using tablet computers onboard the sampling vessels. Sample photographs were collected with the tablet computers and attached to the electronic field data forms. Electronic field data forms were uploaded to the secured field database immediately upon completion. Hardcopy versions of the form were used when electronic field data forms were not available. Field data forms are included in Appendix B. Field activities and sample information were also recorded in field logbooks. For convenience, the R/V Belle is referred to as Boat 1, the R/V Jane B is referred to as Boat 2, and the R/V Good Vibrations is referred to as Boat 3 throughout the field documentation. On 19 August 2017, the R/V Belle was pulled from the water and replaced with the R/V Shocker, which is referred to as Boat 1 from 22 August 2017 to the end of the sampling event. After collection, samples were stored and transported to the field office on ice. Typically, samples were transported to the field office at the end of each day. If necessary, samples were offloaded and transported to the field office by an onshore support team member during the day. Samples were stored on ice overnight in the locked field office to be processed the next day. The onshore support team processed samples (e.g., prepared chains-of-custody, checked labeling, and packed samples for courier pick-up) in accordance with the Work Plan (EA 2017a). Due to the laboratory’s use of a different Laboratory Information Management System (LIMS), separate contaminant of concerns (COCs) were prepared for the samples analyzed for PCB congeners. All other analyses were included together on one COC. Samples were collected from the EA office in Schuylerville, New York, by a courier working out of the Pace Service Center in Schenectady, New York, every day, Monday through Friday. Samples collected on Saturday were refrigerated and stored at the Schuylerville office space and shipped at the earliest possible time on the following Monday. In the event a courier was not available, EA field staff shipped samples via FedEx. Samples were shipped on ice to the appropriate laboratory, and arrived in good condition on time and in temperature, with exceptions noted in Section 2.4.2. All samples were checked into the Pace LIMS at the Pace Minneapolis Laboratory via COCs. Documents, records, photographs, and information relating to field activities were maintained in the project file via electronic files and/or hard copy. Other records of sample collection activities include data collection sheets, chain-of-custody records, custody seals, sample tags, phone conversation records, and corrective action reports. Logbooks and other types of field documentation were copied and/or otherwise digitally reproduced and stored onto a secure server at on a daily basis. Logbooks, sediment data forms, and a photographic log of general onsite activities are included as Appendixes A, B, and C, respectively.

The field investigation activities included collection of additional quality control samples (e.g., duplicates, matrix spike/matrix spike duplicate, etc.) sufficient to meet the requirements of Section 7 of the Generic QAPP (EA 2011c) and the data quality objectives defined in Section 3.4.2 of the Work Plan (EA 2017a). Field and laboratory QC requirements were completed in accordance with Section 7 of the QAPP and Section 3.5.8 of the Work Plan (EA 2017a). Deviations from the Work Plan and QAPP are described in Section 2.4.2. Electronic field data forms, field logbooks, and sample labels were reviewed for completeness and accuracy by the onshore support team during sample processing activities. Internal QA/QC checks were performed throughout the field event and an internal field audit was conducted to document adherence project plans, verify consistency between sample vessels, and review management procedures. The field audit was performed by the Project QA/QC Officer on 14 July 2017 and is included in Appendix D. The Project QA/QC Officer observed and assessed sample collection methods and sample management activities for each of the three sampling vessels and in the field office for compliance with the Work Plan (EA 2017a), Generic QAPP (EA 2011c), and the site-specific QAPP addendum (EA 2017c). No deficiencies or significant observations were identified during the field audit. Internal QA/QC checks on each of the three primary sampling vessels were performed by a Senior Scientist on 12 July 2017, 25 July 2017, 2 August 2017, 3 August 2017, 14 August 2017, and 15 August 2017. Prior to the start of the field effort, the Project QA/QC Officer and Analytical Data Technical Lead performed an onsite audit of Pace’s laboratory in Minneapolis, Minnesota on 1 June 2017. The emphasis of the onsite audit was on the systems in place for sample receipt, sample login, sample custody, processing of data, and reporting in support of the project. Prior to the onsite audit, a document review was completed on Pace’s Standard Operating Procedures (SOPs) and Quality Assurance Manuals supporting the project. No deficiencies or significant observations were identified during the laboratory audit. An Audit Report was distributed to NYSDEC and EA’s Project Manager and is provided in Appendix D. Five PE samples were submitted to Pace for analytical analysis randomly throughout the summer between 31 July 2017 and 25 August 2017. PE samples were used as a measure of accuracy and will be used to establish accuracy limits (upper and lower control limits) for future analytical testing. Four samples were prepared for PCB Aroclors analysis and one sample was prepared for PCB congener analysis. The PE samples were custom made by Phenova, Inc. on 31 July 2017 and were prepared in a manner consistent with the preparation procedures used for the 2009 Phase 1 Remedial Action Monitoring Program (Anchor and ESI 2009) and Phase 2 Remedial Action Monitoring QAPP (Anchor and ESI 2012). PE samples were submitted to Pace as single blind PEs with the samples collected from the site and analyzed for PCB Aroclors, PCB congeners, percent moisture and moisture content. Four sediment PEs were prepared with Aroclor 1221 and Aroclor 1242 mixtures and each with Total Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Project No. 14907.36 Version: FINAL Page 2-10 December 2018 EA Engineering, P.C. and Its Affiliate EA Science and Technology PCB concentrations of 1 milligram per kilogram (mg/kg) and a moisture content of approximately 30 percent. The concentration of each Aroclor and Total PCBs in each PE was as follows: PE/EA Sample Identification 20475-001/RI-PE01 20475-002/RI-PE03 20475-003/RI-PE04 20475-004/RI-PE05 Aroclor 1221 (mg/kg dry) 0.5 0.667 0.75 0.8 Aroclor 1242 (mg/kg dry) 0.5 0.333 0.305 0.2 Total PCBs (mg/kg dry) 1 1 1 1 One sediment PE was prepared with a random mixture of PCB congeners and a moisture content of approximately 30 percent.

All remaining aliquots prepared by Phenova, Inc. are being stored frozen until requested for additional analyses. The results of the PE samples are included in the laboratory hardcopy data packages for sediment samples analyzed by Pace and applicable subcontractors are included in Appendix E. 2.3 FISH SAMPLING Mobilization for the fish sampling field effort commenced on 09 September 2017. On 11 September 2017, sampling commenced using a 20 ft long, semi-v Jon boat outfitted with electrofishing equipment and was completed on 18 September 2017. Work, including sample planning, collection, and processing, was performed in coordination with NYSDEC. The sample collection procedures and analytical testing methods were carried out in accordance with procedures outlined in the Work Plan and NYSDEC Fish Sampling SOPs. Field modifications from the Work Plan sampling procedures were approved by NYSDEC. Fish were collected by means of direct current (DC) pulsed electrofishing and trap netting. Forage fish (primarily Spottail Shiners [Notropis hudsonius]) and Pumpkinseed (Lepomis gibbosus) samples were collected in each reach by means of DC pulsed electrofishing and trap netting. Target sample numbers for each reach were provided by NYSDEC. Target locations in reaches sampled in 2016 by GE/EPA (Reach 5 North, and Reaches 6 through 8) included those previously sampled locations. In reaches not previously sampled, (Reaches 1 through 4 and Reach 5 South) target locations emphasized geographic coverage, with consideration of limitations due to habitat availability. Table 2-2 provides the GPS coordinates of each sampled area and Figures 2-2A through 2-2D depict the actual sampled areas. After an initial training session at the Schuylerville boat ramp provided by a NYSDEC scientist, sample processing activities were conducted in the Schuylerville field office by an onshore support team. The onshore team coordinated several pickups of fish specimens from the on-water team throughout the day to expedite sample processing. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-13 December 2018 Fish scales were collected from Pumpkinseed specimens and submitted to EA’s Deerfield, Illinois, office for age determination. Whole fish samples were submitted to Pace at their lab in Green Bay, Wisconsin and analyzed for PCBs as congeners. Fish samples were also analyzed for percent lipids and percent moisture. A total of 89 Pumpkinseed (or substitute centrarchid) samples and 143 forage fish composite samples were collected for PCB analysis. 2.3.1 Fish Sampling Program Design and Rationale The project objective was to assess and evaluate spatial relationships and temporal trends in Hudson River PCB contamination as reflected by PCB concentrations in fish tissue. The sampling design was consistent with Segment I of NYSDEC’s Long Term Hudson River Remedial Biota Evaluation, PCB Analysis Project, Lower Hudson River Plan (NYSDEC 2003), which targeted yearling Pumpkinseeds and forage species. These species were selected because of their prevalence and residential behavior, which makes them good indicators of local PCB contamination. Fish collection and sample handling methods used were consistent with NYSDEC General Fish Handling Procedures for Contaminant Analysis (NYSDEC 2017). Fish sampling forms can be found in Appendix F. Target sample sizes per reach were determined by NYSDEC based on the minimum fish samples required to perform statistical analyses on the rate of recovery over a 5-year timeframe (NYSDEC 2017). Due to its size, Reach 5 was split into two reaches. Sample locations for the northern part of Reach 5 through Reach 8 were selected based on the location of historical fish sampling areas provided by NYSDEC. Sample locations in Reach 1 through the southern part of Reach 5 were selected to provide adequate geographic coverage to achieve defined statistical objectives. 2.3.2 Navigation A Garmin eTrex Vista HCx GPS receiver was used to aid in navigation during the fish sampling field effort. In Reaches 1-4, the vessel operator used the GPS to navigate to the target locations. In Reaches 5-8, which had been previously sampled, site maps were used primarily for navigation, and the GPS served as an additional aid. Coordinates were recorded at the starting point and end point of fish collection in a particular area. 2.3.3 Fish Sample Collection The R/V navigated to the target sample locations utilizing the GPS unit. Once in position, the boat operator moved the boat slowly through likely fish habitat (e.g., submerged aquatic vegetation). Electrofishing was conducted using a boat-mounted electrofishing system powered by a 6,000-watt generator and output was controlled by a Smith Root Model VVP-15B electrofisher. Output settings were typically maintained at 35% pulse width and 80 pulses per second. Two circular anode arrays connected to extendable booms were used to conduct current to the water with the boat acting as the cathode. For safety purposes, the generator was grounded to the boat and a pedal placed at the bow of the boat provided power to the electrodes only when a dipnetter was standing on the mat. The sampling crew consisted of one driver and two dipnetters. A 3/16-in. mesh dip net was used to collect stunned fish and place them into a live Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-14 December 2018 well. Following collection, stunned fish were sorted and identified by the crew. Fish identifications were verified by the vessel operator, who was an expert in freshwater fish identification. Target fish were placed into a food-grade bag, labeled, and stored on ice. All nontarget fish were returned to the river. Target fish were stored on ice until they were transported to the field office, where they were processed. A fyke net, which is a type of fish trap, was utilized on one occasion when a sufficient number of target species could not be obtained during the sampling day. Personnel deployed the net by setting one end in the tree line and securing it with a metal stake, then slowly moving the vessel backwards away from the shore and feeding the net out. Weighted blocks fixed the net to the bottom and prevented it from drifting downstream with the current. The net was deployed in Reach 1 on 15 September 2017, and was recovered the next day. Target species were collected from the net, and the remaining fish were returned to the river. If sufficient target species (Pumpkinseeds and Spottail Shiners) were not available in a reach, substitutions were made in accordance with the Work Plan Addendum (EA 2017b). NYSDEC provided a list of acceptable substitute species. Redbreast Sunfish (Lepomis auritus) were collected when sufficient Pumpkinseed individuals could not be obtained. When Redbreast Sunfish were collected to fulfill target sample quantities, at least fifteen individuals of that species were collected from the same reach for age verification and subsequent analysis. Substitute forage fish species collected in this event included Spotfin Shiners (Cyprinella spiloptera), Golden Shiners (Notemigonus crysoleucas), Fallfish (Semotilus corporalis), and Emerald Shiners (Notropis atherinoides). Substitute forage fish species were collected in the same quantities as Spottail Shiners. During sample processing, centrarchid fish were measured for total length, weighed, and de-scaled for the aging analysis. Approximately ten scales were collected from each Pumpkinseed and Redbreast Sunfish using a clean knife in accordance with NYSDEC’s General Fish Handling Procedures for Contaminant Analysis (NYSDEC 2003). Scales were collected from the left side of the fish below the lateral line and towards the posterior end of the fish. Scales were placed into individual scale envelopes for age determination analysis. 2.3.4 Analytical Program Frozen fish samples were sent to Pace. Samples were analyzed for PCBs as congeners by gas chromatography/mass spectrometry, with high resolution mass spectrometry required for the 12 dioxin-like congeners. Percent lipid and percent moisture were also determined. Analytical reports were sent directly to NYSDEC. Scale samples from Pumpkinseeds and Redbreast Sunfish were sent to EA’s Deerfield, Illinois, office for age determination. As fish grow, ridge structures called circuli form at the edge of scales with numerous circuli being laid down throughout the year. Fish growth slows or stops during colder winter months resulting in a group of crowded or incomplete circuli rings called annuli, similar to growth rings observed in trees. In the Northern Hemisphere, the birth date of most fish is considered January 1, to account for variability in the formation of annuli among species and Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-15 December 2018 regions (Zale et al. 2012). Both centrarchid species captured during this study spawn in late spring until summer, as such Age 1 fish most likely hatched in the Spring or Summer of 2016 and express a single annulus with numerous circuli towards the edge of the scale representing growth in 2017. Similarly, Age 2 fish most likely hatched in spring or Summer of 2015 and express two annuli. Age determination was performed by one biologist viewing the scales with a dissecting microscope at 20 to 45 times magnification. Approximately 10 or more scales for each specimen were neatly arranged on a glass slide and covered with a second slide to flatten the cupped profile of the scales. Bottom lighting was used to shine through the scales and look for consistent patterns in number and location of annuli. A second scientist provided quality control by observing 20% of the specimens to check for any discrepancies. Discrepancies in age determination can stem from the formation of false annuli called checks and regenerated scales. Checks form during atypical events resulting in slow growth such as extreme weather events, injury, or stress. Indicators of checks include annuli that appear incomplete or two annuli spaced unusually close together. Fish can regenerate scales when loss occurs. Regenerated scales generally lack preexisting growth rings and produce irregular circuli after regeneration, and are therefore, unsuitable for use in accurate age determination (Zale et al. 2012). 2.3.5 Sample Handling, Chain-of-Custody, and Documentation Fish were sorted into separate bags by species, counted, and labeled with the sample location in the field. The labeled bags were stored on ice until they were collected by an onshore team member. Collection location descriptions and number of target species specimens released from the field team to the onshore team were recorded on the NYSDEC Chain-of-Custody form. A separate NYSDEC Chain-of-Custody was filled out for each sample location. Samples selected for laboratory analysis were spread evenly between the target locations within the pool, to the extent possible, to provide adequate spatial coverage. The total length and weight of each fish was measured, and samples were placed into plastic sample bags with a metal tag marked with a unique tag number (TAGNO, the sample identification number). Pumpkinseeds were bagged separately and prepared for analysis on a whole-body basis as an individual. Forage fish were processed as composite samples for analysis. Forage fish of the same species were grouped by body length to have similar-sized individuals in each composite. Larger fish may be longer-lived and are more likely to have acquired higher levels of contaminants in their tissue. Grouping similar-sized fish for analysis reduces any potential sample bias created by larger individuals. Forage fish composites consisted of five to ten individuals, with ten individuals being the target number as per NYSDEC guidelines (NYSDEC 2017). Each composite had a total targeted mass of 10 grams and minimum of 5 grams to ensure sufficient material for analysis. Substitute centrarchids and forage fish species were processed using the same procedures. Sample bags from each location were placed together into a larger, location-specific bag. The TAGNO, species, total length, weight, date collected, collection location (e.g., description, reach, GPS coordinates), method of collection, and collection personnel for each sample was recorded on the NYDEC’s Fish Collection Record Form. Sample bags, reach-specific bags, and Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-16 December 2018 scale envelopes were labeled in accordance with the Work Plan Addendum (EA 2017b). Sample bags were stored in a freezer until the end of the sampling event, when they were shipped to Pace’s laboratory in Green Bay, Wisconsin, for laboratory analysis. All the samples were included on one chain-of-custody. Data recorded in the Fish Collection Record Form were entered into NYSDEC’s fish collection database template on a daily basis. Copies of the Fish Collection Record Forms were included with the Daily Field Reports sent to NYSDEC, and updated database files were submitted periodically. 2.3.6 Quality Control QA/QC field samples were not collected in the fish sampling program. Any QA/QC analyses and results were reported directly to NYSDEC. 2.4 2.4.1 DEVIATIONS FROM THE WORK PLAN, GENERIC QUALITY ASSURANCE PROJECT PLAN, AND FISH SAMPLING PLAN Sediment Sampling Locations Sixty-five of the 1,678 target locations (approximately 4%) locations were removed from the sampling program following initiation due to either inaccessibility or unsafe field conditions. Attempts were made to reach all target locations, and photographs and/or observations of inaccessible locations were recorded. At the direction of NYSDEC, some inaccessible or unsafe locations were moved to an appropriate replacement location close to the original, and others were removed from the program without a replacement. Tables 2-1A–H and Appendix B provide additional details regarding each sample location removed from the sampling program; these inaccessible locations are depicted on the sample results figures presented in Section 3. Of the remaining 1,613 locations, 457 (or approximately 27% of the total target locations) were abandoned due to insufficient sediment recovery. Decisions to abandon locations were made in accordance with Work Plan procedures. Locations were abandoned primarily due to the sediment surface conditions encountered (e.g., bedrock, cobbles, large gravel, woody debris). Descriptions and/or photographs of attempts to collect sediment at abandoned locations are included in the sample field forms included in Appendix B and are described in Tables 2-1A–H; abandoned locations are depicted on the sample results figures presented in Section 3. As the sampling effort was underway, NYSDEC requested that EA add 5 sample locations in Reach 5 to an alcove in Schuylerville, New York that was not previously included in the sample plan. NYSDEC also requested that EA collect 6 additional surface sediment samples and 3 sediment core composite samples from a 1-mile section of the Old Champlain Canal, located in Schuylerville, New York (discussed further in Section 2.4.2). The Old Champlain Canal runs parallel to the Hudson River from Lock 5, where it receives water from the Hudson River, to Fish Creek, a tributary to the Hudson. Locations were selected in consultation with NYSDEC; 2 surface sediment locations were collected upstream of the athletic field near the Canal, 2 adjacent to the Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-17 December 2018 field, and 2 downstream of the athletic field. One core, advanced to refusal, was collected upstream, adjacent, and downstream of the athletic field. 2.4.2 Sediment Sample Collection, Processing and Analytical Program Schedule Sampling was performed in accordance with the planned schedule with a few exceptions. Over the course of the summer, sampling was postponed during hazardous weather events, such as thunderstorms or thick fog, but no full days were lost due to the weather. The R/V Belle did not collect samples on 11-12 July 2017 due to mechanical problems, but resumed sampling on 13 July 2017 following repairs. The R/V Belle was down on 9 August 2017 due to a rusted bearing in a tension pulley; the R/V Belle resumed sampling the next day following repairs. EA had one captain and/or a reduced field crew onsite 23 June 2017, 24 June 2017, 5 July 2017, 4 August 2017, 5 August 2017; only one EA vessel was in operation on these days. The Athena crew was offsite on 21 August 2017 and 22 August 2017; no samples were collected on the R/V Good Vibrations during that time. Despite these delays, sediment sampling was completed ahead of schedule. Sample Collection Samples were collected using the methodology as planned in the Work Plan (EA 2017a), with the following exceptions. On 17 June 2017, the R/V Jane B attempted to collect its first sample using the modified Van Veen sampler and was unable to safely recover the sample due to inadequate winch power. A ponar sampler was used to collect samples on the R/V Jane B from 17 June 2017 until 18 June 2017, and a Van Veen from 19 June 2017 through 22 June 2017. The winch on the R/V Jane B was replaced with a more powerful model on 23 June 2017. A ponar sampler was also used from 22 August 2017 to 30 August 2017 on the R/V Shocker, which was too small to support a modified Van Veen sampler. The modified Van Veen samplers used on the three sampling vessels used the same design; however, the modified Van Veen sampler utilized on the R/V Good Vibrations was slightly smaller (64 square in., 8 in. x 8 in. when in locked open position, 4 in. deep) in scale than those used on the R/V Jane B and the R/V Belle (162 sq. in., 12 in. x 13.5 in. when in locked open position, 6 in. deep). All three samplers provided the required 0–2 in. surface sediment samples. In locations too shallow to safely deploy bathymetric sampling equipment, a stainless-steel probe marked every 6 in. was used to measure water depth. A probe was also used to measure water depth when the vessel was positioned over a slope such that the water depth below the bathymetric equipment was significantly different than the water depth at the sample location. The R/V Shocker used a sounding disk instead of bathymetric sampling equipment to measure depth at locations with water depths less than 2 ft. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-18 December 2018 Old Champlain Canal Area Sample Collection Sample locations were marked out on the banks of the canal using a handheld GPS unit. A small, motorless Jon boat was paddled out from that spot to the approximate center of the canal, and the approximate distance from the marked location was recorded. Once in place, a ponar grab sampler was manually deployed and retrieved from the sampling vessel. A sediment core was collected within a few feet of the grab sample. To collect the core, a 5-ft core tube provided by NYSDEC was manually pushed into the sediment until refusal, was capped, and was then retrieved. Upon retrieval, the second end of the core was capped, and both the grab samples and sediment core were transported to the bank of the canal for processing. The top 2 in. of sediment was collected from the ponar grab sampler and processed using the methods described in Section 2.2.3. Sampling equipment was decontaminated using the methods described in Section 2.2.3. The depth of sediment collected in the core was measured, recorded, and photographed. Water was drained from the core by drilling a hole through the core tube just above the water-sediment interface. The bottom was cap was removed, and all the sediment in the core was deposited into a dedicated aluminum pan. Sediment was thoroughly homogenized and processed using the methods described in Section 2.2.3. Analytical Program The analytical program was performed as planned in the Work Plan (EA 2017a), Generic QAPP (EA 2011c), and site-specific QAPP addendum (EA 2017c), with the following exceptions. One cooler holding 20 samples, collected on 29 June 2017, arrived at Pace’s Minneapolis laboratory out of temperature. Temperature upon arrival was at 8.5 degrees Celsius (ºC), slightly above the quality control limit of 4 ºC ± 2 ºC. The data validator determined that this deviation would not significantly impact data quality; the samples were analyzed per usual. EA directed the lab courier to modify their sample handling procedures to prevent future samples from arriving outside the required temperature range. Eleven TOC samples, including one field duplicate and two equipment blanks, collected on 26 June 2017 were analyzed outside of the 14-day hold time. Samples arrived at Pace’s Minneapolis laboratory on 28 June 2017; however, due to a communication and sample tracking error at Pace’s laboratory, the samples remained in a cooler in the Minneapolis laboratory until 31 July 2017. Samples were received in the Green Bay laboratory on 1 August 2017, and analyzed on 2 August 2017. Several errors were noted in electronic data deliverables (EDDs) submitted by Pace for laboratory samples received through 10 August 2017. Due to the nature of the 1668 PCB congeners analysis, Pace utilized separate LIMS databases for PCB Aroclors and PCB congeners analyses, and generated two separate EDDs to report analytical results. Following discussions with EA, Pace implemented additional QA/QC procedures for future EDD generation, improved internal linesof-communication, and submitted revised EDDs to EA for submittal to NYSDEC. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 2-19 December 2018 Moisture content was analyzed in Pace’s Billings laboratory using the U.S. Department of Agriculture (USDA) 26 method rather than the ASTM D2216 method specified in the QAPP addendum (EA 2017c). As a Corrective Action, Pace subcontracted Atlantic Testing Laboratories in Clifton Park, New York to analyze sediment samples collected from 10 August 2017 through the end of the sediment sampling effort for moisture content via ASTM D2216. Pace’s Billings laboratory continued to analyze sediment samples for moisture content via USDA 26 in order to establish a comparison dataset to assess data previously analyzed via USDA 26. An analysis of the comparison dataset indicates that moisture content results from both methods are in close agreement; a copy of the comparative analysis is included in Appendix E. EA’s field team submitted an additional bag of sample material from every sample location to accommodate this corrective action. Pace provided details on the TOC, EDD, and moisture content analysis issues, root causes, and corrective actions taken in a Corrective Action Report dated 5 September 2017. The Corrective Action Report is included in Appendix G. 2.4.3 Fish Sampling Locations Collection of fish from each target sample location was attempted; however, some actual fish collection locations vary slightly from the planned sample locations. When sufficient fish samples could not be obtained at a targeted location, sample locations were broadened, or additional sample locations were added. In accordance with the Work Plan Addendum (EA 2017b), fish samples collected maintained adequate geographic coverage over the pool. Table 2-2 provides actual fish sample locations. 2.4.4 Fish Sample Processing The number of samples processed and submitted to the laboratory exceeded the number of samples targeted in the Work Plan Addendum (EA 2017b). Four additional forage fish composite samples and 21 additional Pumpkinseed and Redbreast Sunfish samples were collected. Samples were often processed before the entire reach had been sampled. As a result, more samples from the first locations within a pool were processed than were often necessary. Additionally, in Reach 7, Redbreast Sunfish, were submitted as the primary centrarchid species. A minimum of 15 Redbreast Sunfish individuals were required from that reach for age verification and subsequent analysis, surpassing the targeted sample number of 10 Pumpkinseed samples from that reach. At the request of NYSDEC, all processed samples were sent to the analytical laboratory.

Data evaluation, trend analysis, and implications are discussed in Sections 4 and 5. 3.1 DATA MANAGEMENT AND VALIDATION Field collected data, laboratory analytical results, and final validated analytical data were stored in the project-specific EQuIS database stored on EA’s Structured Query Language network server. Automated and manual QC checks were conducted to verify that data were accurately recorded and appropriately input into EQuIS. To assess the quality of analytical data generated as a part of the OM&M investigation, data were validated by an independent data validator, EDS. The Generic QAPP (EA 2011c) addresses implementation of independent validation, in accordance with NYSDEC DER-10. EDS completed a 100% Category A and 20% Category B data validation. EDS prepared data validation reports and updated the EQuIS EDDs with any new or revised results and qualifiers for each sample delivery group. Upon completion of the field investigation, EDS prepared a comprehensive Data Usability Summary Report (Appendix G), inclusive of all sample delivery groups from the investigation, following the guidance provided in Appendix 2B of NYSDEC DER-10. Validation for data usability was accomplished by comparing the contents of the analytical data packages and QA/QC results to the requirements contained in the QAPP, the respective analytical methods, and the laboratory SOPs. The Data Usability Summary Report, with data validation reports and Pace’s Corrective Action Report as attachments, is included as Appendix G. Upon receipt of the updated NYSDEC EQuIS EDDs from the data validator, the data were verified and submitted electronically for upload into the NYSDEC’s Environmental Information Management System in January 2018. In addition to the laboratory results tables, supporting tables such as sample location coordinates were completed as part of the EQuIS EDD submission. Total PCB Aroclor and PCB congener concentrations were calculated by summing the detected concentrations of the individual PCBs and using a value of zero for non-detects (not detected = 0). Field duplicates were excluded from the data evaluation given their potential for introducing statistical bias. EA understands that in future discussions, EPA may recommend a modification to the treatment of non-detects and field duplicates; however, these modifications are not anticipated to have a significant impact on the results of the data evaluation. The data sets used to create maps and data tables, develop the geospatial database, and conduct statistical analysis were queried from the project-specific EQuIS database. The data sets included sample coordinates, reach designations, depths, analytical methods, and validated results. Upon completion of the field effort, NYSDEC requested that several locations be reclassified into a reach different than the original assignment in order to be consistent in how the sediment samples taken in the canal land cuts are assigned on a reach by reach basis. For example, in the land cut between Lock 6 (at the upper end of Reach 6) and the Thompson Island Dam (at the lower end of Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Project No. 14907.36 Version: FINAL Page 3-2 December 2018 EA Engineering, P.C. and Its Affiliate EA Science and Technology Reach 8), the samples collected in the land cut were designated as part of Reach 7 in the field. Ultimately, the data from these locations should not be assigned to Reach 7, but to Reach 8, as the fish in this land cut cannot get to Reach 7 without going over a dam. The sample names were not changed, but the samples were revised in the database to be assigned to Reach 8. All statistical evaluations and discussion of results reflect the changes in reach assignments. Locations reassigned to a different reach are included in the table below.

Summary statistics by reach are presented in Table 3-1. Summary statistics include counts of normal environmental samples, counts of locations with detected and non-detected concentrations, as well as the minimum, maximum, and average detected concentration. The complete sediment results are detailed Tables 3-2A–H and 3-3A–H. Electronic copies of the laboratory hardcopy data packages for sediment samples analyzed by Pace and applicable subcontractors are included in Appendix E. 3.2.1 Polychlorinated Biphenyls – Aroclors A total of 1,269 sediment samples (1,153 environmental samples plus 116 duplicate samples) throughout the eight reaches, excluding 9 samples collected in the Old Champlain Canal, were analyzed for PCB Aroclors. The total PCB results ranged from non-detect to 67.1 mg/kg. The averages in the eight reaches ranged from 0.499 mg/kg (Reach 2) to 5.20 mg/kg (Reach 7). The full set of PCB Aroclor data is presented by reach in Tables 3-2A–H and Figures 3-1 through 3-8. Reach 8 The concentrations of total PCB Aroclors in Reach 8 ranged from 0.0187 to 23.1 mg/kg. Of the Reach 8 sample locations, 39% (82 of 211) had concentrations above 1 mg/kg. Four locations had concentrations above 10 mg/kg; three of these locations (R8-174, R8-182, and R8-191) were spaced out in the northern part of the reach to the west of Rogers Island, and the remaining sample above 10 mg/kg (R8-070) was located mid-reach. Reach 7 The concentrations of total PCB Aroclors in Reach 7 ranged from 0.0297 to 60.9 mg/kg. Of the Reach 7 sample locations, 77% (69 of 90) had concentrations above 1 mg/kg. Eight locations had concentrations above 10 mg/kg. The locations with total PCB concentrations above 10 mg/kg were grouped together mid-river south of Thompson Island, and consisted of an area of approximately 12 acres. Reach 6 The concentrations of total PCB Aroclors in Reach 6 ranged from 0.161 to 19.1 mg/kg. Of the Reach 6 sample locations, 72% (57 of 79) had concentrations above 1 mg/kg. Two locations had concentrations above 10 mg/kg; both of which were located toward the southern end of the reach, just north of the Route 4 bridge. Reach 5 The concentrations of total PCB Aroclors in Reach 5 ranged from 0.0072 to 11.6 mg/kg. Of the Reach 5 sample locations, 34% (91 of 242) had concentrations above 1 mg/kg. Two locations had concentrations above 10 mg/kg; one sample (R5-168) was collected near the cove and the other (R5-137) was collected around the mid-point of the reach.

Of the Reach 4 sample locations, 46% (109 of 238) had concentrations above 1 mg/kg. Three locations had concentrations above 10 mg/kg; samples R4-060, R4-050, and R4-026 were all located at the southern end of the reach, adjacent to the western bank of the Hudson River in Mechanicville and consisted of an area of approximately 6 acres. Reach 3 The concentrations of total PCB Aroclors in Reach 3 ranged from 0.038 to 39.8 mg/kg. Of the Reach 3 sample locations, 49% (53 of 108) had concentrations above 1 mg/kg. Four locations had concentrations above 10 mg/kg; samples R3-014, R3-020, and R3-026 were located at the southern end of the reach, adjacent to the western bank of the Hudson River near Lock 2. These three locations comprised an area of approximately 3 acres. The fourth sample with concentrations above 10 mg/kg was located on the eastern bank of the river, north of Quack Island. Reach 2 The concentrations of total PCB Aroclors in Reach 2 ranged from 0.0294 to 2.36 mg/kg. Of the Reach 2 sample locations, 14% (10 of 69) had concentrations above 1 mg/kg. There were no locations with a concentration above 10 mg/kg. Reach 1 The concentrations of total PCB Aroclors in Reach 1 ranged from 0.0218 to 15.4 mg/kg. Of the Reach 1 sample locations, 20% (23 of 116) had concentrations above 1 mg/kg. One location, R1-135, had a concentration above 10 mg/kg. Old Champlain Canal The concentrations of total PCB Aroclors in the Old Champlain Canal samples ranged from 0.0.0874 to 50.1 mg/kg. Of the canal sample locations, 33% (3 of 9) had concentrations above 1 mg/kg. Two locations, R5-OC3 and R5-OC5, had a concentration above 10 mg/kg. 3.2.2 Polychlorinated Biphenyls – Congeners A total of 129 sediment samples (115 environmental samples plus 14 duplicate samples) were analyzed for PCB Congeners. The total PCB congener results ranged from 0.016 to 42.5 mg/kg. The averages in the eight reaches ranged from 0.356 to 8.08 mg/kg. The full set of PCB congener data is presented by reach in Tables 3-3A–H. 3.2.3 Total Organic Carbon A total of 1,269 sediment samples (1,153 environmental samples plus 116 duplicate samples) were analyzed for TOC. Sediment in the Upper Hudson River contained organic matter, with TOC Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 3-5 December 2018 ranging from 496 to 90,500 mg/kg. The averages in the eight reaches ranged from 8,310 to 19,300 mg/kg. The full set of TOC data is presented by reach in Tables 3-2A–H. 3.2.4 Grain Size The sediment type for each sample was visually described in the field based on general soil characteristics including an estimate of the amount of fine sand, medium sand, coarse sand, gravel, silt, clay, and organic/other matter such as wood chips and presence of observable biota. The sediment descriptions are also included in the field database provided in Appendix B. Grain size analysis was conducted to further confirm the sediment type noted in the field. A total of 1,275 sediment samples (1,159 environmental samples plus 116 duplicate samples) were analyzed for grain size. This includes the 6 surface samples collected in the Old Champlain Canal. Of the 1,159 environmental surface sediment samples submitted, 74 (6%) were primarily comprised (greater than 50%) of gravel, 781 were primarily sand (67%), 243 were primarily fines (21%), and the remaining 61 samples (5%) were a mixed assemblage of sediments. Particle size graphs are provided in Appendix H and the full set of grain size data is presented by reach in Tables 3-2A–H. Using the USCS classifications as determined by the laboratory, samples were classified by their dominant grain size category (50% or greater) into the type categories listed below. Samples that did not have a 50% dominant grain size category and exhibited a mix of fine sand to gravel were identified as Type IV (transitional), in accordance with the GE/EPA procedure. • Type I (clay, silt, fine sands): Smooth, generally featureless bottom; principally composed of soft aqueous silty sediments. Consists of samples with 50% or more sediments smaller than Sieve No. 200. Polygon Layer: Silt. • Type II (sands): Smooth to mottled bottom; principally composed of semi-compact to compact sand deposits. Consists of samples with 50% or more sediments smaller than Sieve No. 4. Polygon Layer: Sand. • Type III (coarse gravel and sand mixtures): Irregular bottom; principally composed of compact gravel and cobble deposits intermixed with sand. Consists of samples with sediments more than 50% larger than Sieve No. 4. Polygon Layer: Gravel. • Type IV (mixed sediments): Smooth and irregular bottom; a varying assemblage of sediments typically associated with Types I, II, and III. Polygon Layer: Transitional. • Type V (rocky): Extremely irregular bottom; principally composed of bedrock, cobbles, and/or boulders that are often overlain by a variable thickness of unconsolidated sediments. • Bedrock. Polygon Layer: Bedrock.

Laboratory data were verified against the lithology descriptions in field logs and sample photographs prior to updating the maps to ensure that each location was assigned the most appropriate grain size. Locations that were abandoned in the field were examined on a case-by-case basis using field logs, photographs, and probing observations to determine the appropriate grain-size assignment. Grain size (sediment type) polygons are shown on Figures 3-1 through 3-8. 3.3 RESULTS FROM FISH SAMPLING A total of 89 composite forage fish samples and 143 centrarchid samples were collected and processed in the September 2017 field effort. Five different species were used for the forage fish samples, and two species were used for the centrarchids. Sample quantity goals for each reach were achieved for both forage fish and centrarchid numbers (Table 3-4). As discussed in Section 2.3, frozen samples were sent to Pace and analyzed for PCBs as congeners, percent lipids, and percent moisture. Analytical reports were sent directly to NYSDEC and are not available at the time of this report. Scale samples from Pumpkinseeds and Redbreast Sunfish were sent to EA’s Deerfield, Illinois office for age determination. Scales from 120 Pumpkinseeds with total lengths ranging from 81 to 121 millimeters were submitted for aging. Of those samples, 5 fish were determined to be two years old while the remainder were one year old. Scales from 23 Redbreast Sunfish ranging from 80 to 110 millimeters were also submitted for aging, with one specimen being 2-years old and the remainder being 1-year old. Age determinations were added to the NYSDEC fish collection database for the Fall 2017 effort. 3.4 RESULTS FROM GENERAL ELECTRIC/UNITED STATES ENVIRONMENTAL PROTECTION AGENCY 2016/2017 HUDSON RIVER PCB SEDIMENTS INVESTIGATION Results from the EPA/GE 2016 sampling event are summarized in the 2016 Surface Sediment Sampling Data Summary Report (Anchor 2017). As discussed in Section 2.2.1, the sample data collected from 215 locations in the non-dredged areas from the 2016 investigation were used in sample program design and in the data evaluation presented in Section 4. The EPA/GE data used in EA’s evaluations are summarized in Table 3-5 and PCB concentrations are presented in Figures 3-1 through 3-8. The second part of EPA/GE’s investigation included sampling of the dredged areas in the Upper Hudson River. This study was completed in the Fall of 2017, after the NYSDEC OM&M field effort. Data from all EPA/GE events will ultimately be used in conjunction with data collected as part of the NYSDEC’s effort to establish the baseline conditions following the remedial action in OU-2. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Project No. 14907.36 Version: FINAL Page 4-1 December 2018 EA Engineering, P.C. and Its Affiliate EA Science and Technology DATA EVALUATION As described in Section 1 of this Data Summary Report, the objectives of the OM&M sampling and evaluation activities were to monitor and evaluate the performance of the EPA‐lead Hudson River PCB Sediments Site dredging and monitored natural recovery remedy through the collection of a sufficient number of samples to conduct a statistical analysis and to establish baseline postdredging concentrations of PCBs in the Upper Hudson River. Specifically, the data quality objectives related to the application of the data were as follows: • Conduct statistical analysis to characterize results, explore relationships, and establish a baseline for future studies including calculation of simple average PCB concentrations for each reach. • Collect and analyze samples to detect an 8% annual change in total PCBs in surface sediment in non-dredged areas over a 5-year timeframe with statistical power of 80% for each of 8 river reaches. • Provide a basis of comparison for other post-remedy efforts with different study designs to determine whether such designs are adequate. Following sample collection, analysis and reporting described in the previous sections of this report, EA developed a geospatial database and conducted statistical analyses to characterize chemical analytical results, explore relationships between samples and sampled areas, and establish a baseline for future remedy performance monitoring. The final 2017 validated analytical laboratory data and EPA/GE 2016 sample data (Anchor 2017) were used to calculate the simple average for Total Aroclors by reach and evaluate general trends and statistics to evaluate the performance of the EPA‐lead Hudson River PCB Sediments Site dredging and monitored natural recovery remedy. 4.1 POLYCHLORINATED BIPHEYNYL SURFACE SEDIMENT AVERAGE CONCENTRATION CALCULATION The sample collection effort described in Section 2.0 involved the collection of surface sediment samples in both non-dredged and dredged areas in the Upper Hudson River for laboratory analysis. The OM&M design/sampling size targeted for each reach was established based on a statistical evaluation of previously collected data as described in the Work Plan (EA 2017a). Sample locations were selected using a triangular systematic sample grid with a randomly selected starting point. The samples collected using this gridded approach were used as the basis for calculating simple averages. Simple average concentrations were calculated independently by river reach using a stratified sampling design as described in GE’s Surface Sediment Sampling Work Plan for 2016 Hudson River PCBs Superfund Site (Anchor 2016) with the strata consisting of dredged versus nondredged areas. Details of the simple average computation methodology are discussed in Section 4.1.1. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Project No. 14907.36 Version: FINAL Page 4-2 December 2018 EA Engineering, P.C. and Its Affiliate EA Science and Technology 4.1.1 Method for Computing Average Recoverable Sediment Concentrations The average concentrations of total Aroclors in recoverable sediment was computed for each of the eight river reaches. For a given reach, the simple average was computed as the simple arithmetic mean of the dredged and non-dredged total Aroclor concentrations. where: 𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅ℎ 𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀 = 1 �(𝑁𝑁𝑖𝑖 × 𝑥𝑥̅𝑖𝑖 ) ∑ 𝑁𝑁𝑖𝑖 𝑖𝑖=1 𝑖𝑖 = index for dredged vs. non-dredged strata, 𝑁𝑁𝑖𝑖 = number of recoverable sediment samples within strata 𝑖𝑖, and 𝑥𝑥̅𝑖𝑖 = arithmetic mean total Aroclor concentration of recoverable sediment within strata 𝑖𝑖. The variance of the reach mean was similarly computed as the sample-weighted average of the dredged and non-dredged variances in total Aroclor concentrations. where: 𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅ℎ 𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉𝑉 = 1 �(𝑁𝑁𝑖𝑖 × 𝑠𝑠𝑖𝑖2 ) ∑ 𝑁𝑁𝑖𝑖 𝑖𝑖=1 𝑠𝑠𝑖𝑖2 = sample variance of total Aroclor concentrations in the recoverable sediment region within strata 𝑖𝑖. Additional summary statistics (e.g., skewness and standard error of the mean) were also computed for each reach strata, and Q-Q plots developed in order to aid in characterizing the distribution of total Aroclor concentrations. Statistical intervals for both the strata means and the reach means were computed using the following two methods: 1. ±2* standard error of the mean (SEM), and 2. The two-sided 95% confidence limits using the Cantelli’s generalization of the Chebyshev inequality for univariate sample data. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Project No. 14907.36 Version: FINAL Page 4-3 December 2018 EA Engineering, P.C. and Its Affiliate EA Science and Technology As described in EPA’s ProUCL Version 5.1.002 Technical Guide, the two-sided Chebyshev inequality confidence interval was computed as where: 1 𝑠𝑠𝑥𝑥 95% 𝐶𝐶𝐶𝐶 = ∓�� − 1� × 0.025 √𝑛𝑛 𝑛𝑛 = the number of samples used to compute the sample variance. As described in the ProUCL technical guide, confidence intervals computed from the Chebyshev inequality requires no distribution assumption, but provides conservative estimates of the confidence limits. Following recommendations in the GE Work Plan (Anchor 2016), the relative errors were computed for each river reach as 𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅 𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸 = (95% 𝑈𝑈𝑈𝑈𝑈𝑈𝑈𝑈𝑈𝑈 𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶 𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿 − 𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀) 𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀 Non-detect results were treated as zero for purposes of simple average calculations (Section 3.1). Field duplicate samples were excluded from the analysis (Section 3.1). 4.1.2 Average Concentration Results Q-Q plots for total Aroclor concentrations in the dredged and non-dredged areas of each reach are presented in Appendix I. The Q-Q plots show that the sample concentrations tend to be highly positively skewed, meaning that there is a low frequency of high total Aroclor concentrations in most of the reaches sampled. Trend analysis and computing reasonable confidence intervals for means of highly skewed data sets is challenging, and it is recommended that further analysis be conducted to determine alternative data analysis approaches that may be able to better control variability, such as data transformations, identification of covariates, alternative stratification approaches, etc. Computed arithmetic averages are presented in Table 4-1 and Figure 4-1; averages are presented for each reach using the combined 2017 data set and 2016 EPA/GE data. Averages were calculated on a total reach basis as well as for the dredged and non-dredged areas within each of those reaches. For each scenario, 95% confidence limits (CLs) and relative error (RE) are provided. On a reach-wide basis, the highest average value was measured in Reach 7 with a value of 4.83 mg/kg. The lowest average values were measured in Reach 2 (0.44 mg/kg), followed by Reach 1 (0.68 mg/kg), Reach 5 (1.44 mg/kg), Reach 4 (1.41 mg/kg), Reach 8 (1.85 mg/kg), Reach 3 (2.10 mg/kg) and Reach 6 (2.40 mg/kg). The upper 95% confidence limit was above Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 4-4 December 2018 1 mg/kg in all reaches, with the exception of Reach 2 (0.77 mg/kg).

The non-dredged area simple average value was 0.68 (0.00, 1.40) mg/kg. 4.2 POWER ANALYSIS The initial goal set for the sampling program was to collect a sufficient number of samples within each reach to evaluate an 8% annual decline in mean sediment PCB concentrations within a given reach between two consecutive 5-year monitoring periods with a statistical power of 80% at the Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Project No. 14907.36 Version: FINAL Page 4-6 December 2018 EA Engineering, P.C. and Its Affiliate EA Science and Technology 95 percent confidence level. To meet this goal, two sets of analysis were performed. First, a statistical analysis was performed on past sampling data, both the SSAP historical data (2003–2005), and the recent EPA/GE (2016) data from the non-dredged areas were considered. The SSAP historical data resulted in a more conservative number of samples and was ultimately used as a basis for the power analysis, provided in Appendix C of the Work Plan (EA 2017a). The statistical analysis was used to establish the target sample number for data collection in 2017 (EA 2017a); this resulted in the data collection efforts and results presented in Section 2.0 and 3.0 of this report. Second, a power analysis was performed on the newly collected 2017 data to test the power of the study design and set a basis for future comparisons. Appendix C of the OM&M Letter Work Plan (EA 2017a) describes the method used to satisfy the statistical design objectives using power analysis. As described in Appendix C, the power analysis required specification of the standardized difference between the two means (𝑑𝑑) corresponding to an 8% annual decline over 5 years: where: 𝜇𝜇0 𝜎𝜎 𝑑𝑑 = 𝜇𝜇0 �(1−0.08)5 −1� 𝜎𝜎 (1) = mean sediment PCB concentration in baseline year = standard deviation of PCB concentrations. As described below, 𝑑𝑑 was estimated using an analysis of both the SSAP historical data, and the recent EPA/GE 2016 sample data in the non-dredged areas. A power analysis was conducted independently for each river reach. A total sample number of 1,673 was selected for the baseline sediment monitoring event to provide a representative baseline data set to support future analysis as discussed in Section 2.2.1. An actual number of 1,153 samples were collected during the baseline sediment monitoring event. Section 2.4.1 and Appendix B discusses the deviations from the proposed sample number. The power achieved from the combined 2017 and 2016 EPA/GE data, using the parameters described above, is provided in Table 4-2. The power for most of the reaches is well below 80%. The result is not surprising considering the highly skewed datasets that confound the statistical power to detect modest changes over time. The simple averages calculated using the 2017 and 2016 EPA/GE data are significantly less than predicted using historical data, but the variances are about the same. Thus, the power to detect a decrease in the mean concertation is significantly less than what had been estimated from the SSAP data. While the power is less than anticipated, the 2017 data in combination with the 2016 EPA/GE data provides the most representative data set available for baseline analysis. The baseline dataset should be used to adapt the sampling strategy for the monitoring program to increase statistical power. As described in Section 5, this may include using the spatial patterns in the baseline data to better inform the post-remedy conceptual site model and future monitoring. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology 4.3 EA Project No. 14907.36 Version: FINAL Page 4-7 December 2018 ADDITIONAL TREND ANALYSIS AND EVALUATION PCB data were further evaluated to identify any evidence of trends relating concentrations to TOC or grain size and to evaluate relationships between Aroclor concentrations and Tri+PCB congeners. These analyses are presented in the section below. 4.3.1 Evaluation of GE’s Tri+PCB Regression Equation EA performed an assessment of the regression relationship historically considered during data evaluation efforts on the Hudson River whereby total PCB concentrations are evaluated in terms of Tri+PCB or the sum of PCB Congeners with three or more chlorine atoms. The results of this evaluation (provided in additional detail in Appendix J) suggested for the purposes of long-term monitoring and trend analysis NYSDEC should consider conducting future statistical evaluations using total Aroclor data. If it becomes necessary to estimate Tri+PCB, then it is recommended that an alternative model be developed. 4.3.2 Correlation Analysis between Polychlorinated Biphenyls and Sediment Characteristics To examine the baseline dataset for associations between PCBs, grain size and TOC, Pearson correlation coefficients and associated probability values were calculated relating individual PCBs, percentage of fines, percentage of sand, and percentage TOC. These values are presented in Table 4-3. Aroclor 1221 and Aroclor 1254 did not exhibit significant correlations with grain size. Aroclor 1242 exhibited a very weak ( r < 0.1), but statistically significant (p < 0.05) correlation with grain size. Aroclors were significantly correlated with TOC (p < 0.05); however, the correlations were weak (r < 0.3). Tri+ PCBs were not significantly correlated with TOC or grain size (Table 4-3). The weak correlations found between PCBs and both grain size and TOC, suggest future trend analysis may not benefit appreciably by incorporating grain size or TOC as ancillary factors. However, this analysis is specific to the baseline data set. Future sampling efforts and results could be used to further examine these associations.

Each of these factors affect the way data may be used for comparisons between monitoring events, and bear implications for future monitoring efforts. 5.1 POLYCHLORINATED BIPHENYL CONCENTRATIONS AND SPATIAL VARIABILITY Section 3.0 presents the range of PCB concentrations detected in each reach. Total PCB Aroclor concentrations span a broad range, from non-detect to over 60 mg/kg. Some reaches demonstrate greater ranges and variability than others. Review of PCB distribution shows that the some elevated detects are located in dredged areas, while others are located in non-dredged areas. Highest detections (i.e., over 10 mg/kg) tend to be found at individual locations or in small clusters of samples; the area represented by these samples varies by reach, but is sometimes as small as 1 to 2 acres. Detections between 1 mg/kg to 10 mg/kg tend to occupy broader areas, with clusters of 5 to 10 samples in some reaches. In many reaches, there are some large areas with concentrations less than 1 mg/kg. These patterns, coupled with high variability evidenced by the upper and lower prediction limits associated with the simple averages (Table 4-1), indicate that future sampling efforts should account for reach-specific variability in study design and should consider whether non-systematic sampling might not capture the full range of variability at the Site. Future data sets should be reviewed for spatial patterns. These findings also indicate that reaches should not be grouped into river segments without close consideration of intra-reach variability, as this may combine populations with inconsistent variances. The influence of higher concentration areas also indicates that use of different measures of central tendency should be approached with caution as it may exclude the influence of these areas. 5.2 SIMPLE AVERAGE OF RECOVERABLE SEDIMENT BY REACH Simple average calculations identify that two river reaches (Reaches 1 and 2) have simple averages < 1 mg/kg (Reach 1 and 2), three river reaches (Reaches 8, 5, and 4) have simple averages > 1 mg/kg and < 2 mg/kg total PCB Aroclors, two (Reaches 6 and 3) have simple averages > 2 mg/kg and < 4 mg/kg, and one reach (Reach 7) has a simple average > 4 mg/kg. The difference in simple average between reaches, especially between non-contiguous reaches, and the fact that reaches represent a relevant exposure grouping for fish, indicates that reaches should continue to be evaluated separately for long-term sediment monitoring efforts.

This is because the baseline data set demonstrated greater variability overall and for many individual reaches than that demonstrated by the SSAP data set alone. To satisfy the specific statistical design objectives specified by the NYSDEC: 1. The ability to detect an 8% annual decline in mean sediment PCB concentrations within a given reach between two consecutive 5-year monitoring periods with a statistical power of 80% at the 95% confidence level. 2. For any given monitoring year, the number of samples collected should be sufficient to determine the arithmetic mean PCB concentration for each reach with a relative error no greater than 20 percent. The relative error is defined in GE’s Surface Sediment Sampling Work Plan for 2016 Hudson River PCBs Superfund Site (Anchor 2016) as the difference between the 95% upper confidence limit and the sample the mean divided by the mean: 𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅 𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸 ≡ 95% 𝑢𝑢𝑢𝑢𝑢𝑢𝑢𝑢𝑢𝑢 𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐 𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑎𝑎𝑎𝑎 − 𝑚𝑚𝑚𝑚𝑚𝑚𝑚𝑚 𝑚𝑚𝑚𝑚𝑚𝑚𝑚𝑚 The following actions/evaluations are recommended for consideration: 1. Evaluate spatial distribution and fate and transport to develop an updated post-remedy conceptual site model, and use this information to direct sampling/monitoring to areas of higher variability. 2. Substitute the arithmetic mean for a more robust statistic such as the median, with separate concurrent evaluation of the importance of areas of higher concentrations. 3. Include in the evaluation the dredged area data from the second component of the first year of the EPA-lead OM&M sediment sampling program, (126 locations anticipated) when available. The addition of these data may improve the power of the analysis; however, it could also channel means and variances. 4. Collect more samples to increase statistical power. The practicality of this recommendation would need to be considered within the limitations of the physical conditions and logistical constraints of the river system. 5.4 ANALYSIS OF ADDITIONAL TRENDS The relationship between total PCB Aroclors, grain size, TOC, and Tri+ PCB congeners was evaluated to determine whether these factors may influence concentration distributions. Analyses to test for correlations between PCBs and TOC on both an overall and reach-specific basis identified several significant but weak correlations between TOC and specific PCBs. Significant correlations between PCBs and grain size were not identified. Hudson River PCB Sediments OU-2 Site (546031) Upper Hudson River, New York Data Summary Report EA Engineering, P.C. and Its Affiliate EA Science and Technology EA Project No. 14907.36 Version: FINAL Page 5-3 December 2018 Analysis of trends relating total PCBs, individual Aroclors, and Tri+ PCBs indicate a high level of correlation. There is a high degree of multicollinearity between Aroclors; therefore, the use of regressions that consider each Aroclor separately are not advised unless Aroclor covariance is measured and used to modify the equation on a dataset-specific basis. Total PCB concentrations are considered a more direct indicator of Tri+ PCB concentrations. 5.5 SUMMARY The 2017 baseline sampling program found higher variability than expected. High concentrations of total PCB Aroclors observed within the data sets positively skewed the distribution of results, resulting in higher sample means and variances. Future monitoring and data interpretation should consider the influence of distinct areas with higher concentrations, which could be an important contributor to fish exposures. Given inter-reach variability, data evaluation indicates that comparison with future data sets should be performed on a reach-by-reach basis. Total PCB Aroclors are considered a better metric for tracking PCB concentrations over time than Tri+PCB concentrations estimated from Aroclor-Tri+PCB regression equations that add additional and unnecessary uncertainty. Due to the observed distribution of total PCB Aroclors characterized by a small number of sample results with large concentrations, it is unlikely that a modest decline in PCB concentrations can be identified with a lower number of samples. Future sampling should consider the highly skewed nature of total PCB Aroclor concentrations. Populations with skewed distributions require additional sampling effort beyond that required to characterize populations that are normally distributed. In addition, future data interpretation and statistical analysis should account for the positively skewed data distributions considering the use of a robust measure of central tendency, and characterizing the influence of the upper end of the concentration distribution on fish exposure.
