The parcels are identified by the Northampton Assessor as Lots 39-031, 39-040 and 39A-046, and are referred to collectively in this report as "the Site". A Site locus is provided as Figure 1. This environmental assessment was conducted by O'Reilly, Talbot & Okun Associates, Inc. (OTO) on behalf of the City of Northampton, which is considering purchase of the property for conservation purposes. Our objective was to render an opinion as to the potential presence of oil or hazardous materials (OHM) in Site soil and groundwater. Based on the undeveloped nature of the Site and surrounding properties, the City requested a limited evaluation, which included a Site reconnaissance and soil sampling in suspect areas. This report is subject to the Limitations in Appendix A. 2.0 BACKGROUND This section presents information on the Site setting, drainage, mapped features, land ' use, and history. 2.1 SITE DESCRIPTION The Site is an approximately 19.5 acre area comprised of three parcels of land near the intersection of Routes 5 and 91 and Hockanum Road at the southern end of Northampton. The three parcels are listed in Assessor's records as having the categories and acreage: Lot Number Type Acres 39-031 Tillable 6.00 Wasteland 6.84 39-040 Woodland 5.65 39A-046 Forest 0.98 a The Site is bisected by the Mill River, with Lots 39-040 and 39A-046 on the west side of the river, and 39-031 on east. A Site plan showing the three parcels is provided as Figure 2. There are no buildings on the Site. The property is undeveloped and mostly wooded land within the Mill River floodplain. Each of the parcels is zoned SC (Special Conservancy). Abutting properties include woodland and farmland on the north, south and east, and railroad tracks on the west. I U Page 1 O'Reilly, Talbot & Okun [ A S S O C I A T E S] 1 - 2.2 DRAINAGE AND HYDROLOGY The Site is nearly 20 acres in size, therefore drainage and topography across the property vary. However, in general, surface water and groundwater in this area are anticipated to flow towards the Mill River and/or Connecticut River, generally to the south or southeast. No subsurface explorations were conducted by OTO to confirm the estimated flow direction. The Northampton Department of Public Works (DPW) indicated that a pumping station is located just north of the Site, and actively pumps stormwater from the downtown area into the Mill River in this area. DPW plans indicate a subsurface drain line crosses the northern tip of Lot 39-031, near Hockanum Road. 2.3 MASS-GIS MAPPED FEATURES Mapping of the study areas was viewed on the Massachusetts Geographic Information System (MassGIS) website, hqp://www.mass.gov/mgis/m42ing.htm. This website contains information on the locations of wetlands, protected wildlife habitat, potential drinking water sources, and other information relevant to environmental investigations. A copy of the priority resource map is provided in Appendix B. LJ The Site is mapped as being within a medium yield aquifer. Based on this mapping, groundwater below the Site would be considered a Current or Potential Drinking Water u Source Area as defined in 310 CMR 40.0006. Groundwater in the area is therefore u classified as RC-GW1 for the purposes of release reporting under Section 40.0360 of the Massachusetts Contingency Plan (MCP). MassGIS mapping indicates the entire Site lies within the 100 year floodplain, and a significant portion of the Site is freshwater wetlands. No certified vernal pools or Areas of Critical Environmental Concern are present on or within 500 feet of the Site. ~l 2.4 CURRENT AND PAST SITE USE u . The Site is currently undeveloped, and not used for any formal purpose. As described in Section 3.0, hiking and unauthorized camping appears to occur in some portions of u the property. ~J 2.4.1 Historic Topographic Maps To evaluate whether the Site had been developed in the past, we reviewed historic topographic maps (UNH, 2006) dated 1901, 1941 and 1948. No buildings, roads, or other indication of development were present on Site in those maps. Page 2 1 ~ r n O'Reilly, Talbot & Olcun [ A S S O C I A T E S] 1 1 2.4.2 Historic Aerial Photograbh J An aerial photopograph of the area taken in 1986 was reviewed at the Northampton Department of Public Works. The photograph shows what appears to be an oval dirt track, as might be used for car racing, in the center of Lot 39-040. The track appears to have been accessed by a dirt road leading from an automotive junk yard to the south. The former location of the track was not evident during our Site reconnaissance (Section 3.2). In 1986, the northern portion of Lot 39-031 was not as heavily wooded as it is today. A dirt road was visible in this area. Several vehicles and what appears to be an area of stockpiled haybales are present along the road. The land to the north and south of Lot 39-031 appeared to be agricultural fields in the aerial photograph. No indication of filling was observed on the three lots. A copy of the relevant section of that photograph is provided in Appendix B. 2.4.3 State Listed Release Sites The MassDEP on-line sites list (MassDEP, 2006a) was reviewed to identify state-listed releases at or abutting the Site. None were identified. 2.4.4 Landfills u Lists of active and closed landfills (MassDEP, 2006b and 2006c) were reviewed for information on facilities in Northampton. No active or closed landfills were identified I~ at or abutting the Site. k~ Based on the above information, the Site is and has been historically undeveloped. A u dirt road off of Hockanum Road was present in the northern portion of the Site, and LJ was used for farming equipment. No state-listed releases or current or past landfills were identified on or abutting the Site. 3.0 SITE RECONNAISSANCE A Site reconnaissance was conducted on September 27, 2006 by Valerie Watanabe of OTO. The weather was clear and sunny at the time. The entire length of the Site was traversed on foot during the course of this visit. While our reconnaissance was intended to cover the entire property, we cannot guarantee that all areas were observed, particularly in the heavily wooded central section of the Site. Our reconnaissance focused on areas where past human activity was evident. There are no buildings on Site, therefore our observations are exterior only. Photographs of certain features discussed in this section are provided in Appendix C. Page 3 I O'Reilly, Talbot & Okun 4-- [ A S S 0 C IA T E S] 1 3.1 LOT 39-031 Lot 39-031 is the portion of the Site east of the Mill River. The northern half of this lot contains an overgrown dirt road, along which are abandoned farm equipment and other miscellaneous debris. The southern half of this lot shows little indication of human activity, and is heavily wooded, with no roads and few paths. The dirt road in the northern portion of Lot 39-031 begins just north of Hunts Road, and extends to the southwest off of Hockanum Road. A vertical metal pipe that appears to be an irrigation line is present on Lot 39-031 approximately opposite Hunt's Road. The old dirt roadway on this parcel is overgrown and does not appear to have been used recently. The area along the roadway appears to have been used as an informal solid waste disposal area in the past. Items observed along the road included two pieces of abandoned farm equipment, at least 15 tires, broken furniture, bricks, asphalt, an approximately 300 to 500 gallon cracked plastic tank, and an old dumpster. The dumpster is nearly empty, with a few inches of what appears to be nonhazardous trash in the bottom. The ground surface along the dirt road is uneven, and characterized by the presence of numerous irregular hummocks. During our reconnaissance, OTO dug into the sides of multiple small piles at random, to depths of up to one foot. The material encountered appeared to be topsoil with no visible debris. Coal ash/slag was observed on the ground surface at 42° 18' 27" N, 72° 37' 17" W. Based on surficial observations, less than one cubic yard of material was present. A small wooden platform that appears to be a fairly recent construction was present beyond the end of the dirt road, at GPS coordinates 42° 18' 34" N, 72° 37' 11" W. The section of the Mill* River that abuts the northern portion of the Site was broad, n shallow, and slow flowing. The water surface is nearly entirely covered with vegetation, L I so conditions in the river could not be observed. However, occasional large diameter pieces of metal debris and at least one tine were observed breaking the water surface, LJ suggesting some solid waste materials were historically deposited in the river. A u photograph of one such item, possible an old automotive gasoline tank, is provided in Appendix C. No sheen or odors were observed indicative of an oil or hazardous U material release to the water were observed. ~J 3.1.1 Sample Collection Two soil samples were collected from Lot 39-031, at the locations shown on Figure 2. Photographs are provided in Appendix C. The first sample, S1, was collected from an approximately five foot by five foot area where the ground surface had a black stained color, and no vegetation was growing. Nearby materials on the ground surface included an empty one-gallon lacquer thinner jug and about a dozen old automotive tires. The L Page 4 (7) T O'Reilly, Talbot & Okun 4--- - [ A S S O C I AT E S] 1 sample was collected from the upper three inches of soil, in the stained area. GPS coordinates of sample location S1 are 42° 18' 37" N, 72° 37' 11" W. Soil sample S2 was collected from a shallow pit, approximately 15 feet across, located about 50 feet southwest of Hockanum Road. The pit contained a torn piece of polyethylene sheeting with an estimated half a cubic foot of Speedi-dry type absorbent clay material. No soil discoloration or sheen was observed on the ground surface, but trash was present. GPS coordinates of this sample location are 42° 18' 34" N, 72° 37' 11" W. 3.1.2 Sample Analysis and Results The two soil samples were submitted to Spectrum Analytical Laboratory of Agawam, Massachusetts for analysis of extractable petroleum hydrocarbons (EPH) with target polycychc aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and RCRA-8 metals. Analytical results are summarized on Tables 1 (organics) and 2 (metals). A copy of the laboratory report is provided in Appendix D. As shown on Table 1, EPH, PAHs, and PCBs were not detected in the soil samples. Table 2 provides analytical results for metals in the soil samples. Metals, which are natural constituents of soil, were detected, but at concentrations below MCP Reportable Concentrations (RCS-1). 3.2 LOTS 39-040 AND 39A-046 Lots 39-040 and 39A-046 comprise the portion of the Site west of the Mill River. These two lots are wooded, with the exception of a a small open field in the southwestern portion of the Site, east of the railroad tracks. The field is believed to be the historic location of a small dirt oval race track. The former location of that feature was not evident during our reconnaissance. The ground surface in this area is flat and generally free of debris, except for occasional patches of shattered automotive safety glass. There are multiple footpaths, but no old roadways were identified in the wooded portions of these two lots. However, a large pile of angular boulders within the woods (42° 18' 27"/72° 37' 17") suggests truck access was historically available. A small solid waste fill area was observed near the boulders, at 42° 18' 27" N, 72° 37' 17" W. Materials present on the ground surface included broken milk bottles, canning jars, pottery shards, and other items typical of historic residential solid waste. Two automobile tires appear to be a more recent addition. No indication of OHM disposal was observed in this area. A modern tent camp that appears to be abandoned is present at 42° 18' 27" N, 72° 37' 17" W. The area is arranged with camp f u-niture and littered with clothing and garbage. Page 5 O'Reilly, Talbot & Okun [ A S S O C I A T E S] 1 The campers appear to have used a nearby gully as a waste disposal area. An estimated two to three cubic yards of trash bags, cans, bottles, old clothing and other debris are partially buried under soil in the gully. The waste materials did not appear to contain OHM. In summary, no indication of a specific reportable release of oil or hazardous materials was observed on Site. Portions of the Site are littered with solid waste and other debris. A small volume of coal ash and slag were observed on the ground surface in Lot 39- 031. 4.0 SUMMARY AND CONCLUSIONS 1 A Limited Environmental Site Assessment was conducted on three lots of undeveloped land in Northampton, Massachusetts. This assessment consisted of: a review of historic maps and aerial photographs, a review of state listed release sites in the area; a Site reconnaissance; collection and analysis of two surficial soil samples; and preparation of this report. Section 4.1 summarizes our findings; Section 4.2 provides our conclusions and recommendations for this Site. 1 4.1 SUMMARY Description and Setting The Site comprises three parcels in the Meadows section of Northampton, Massachusetts. The Site is bisected by the Mill River, with Lots 39-040 and 39A-046 on the west side of the river, and 39-031 on east. There are no buildings on the Site. The property is undeveloped and mostly wooded land within the river floodplain. Each of the parcels is zoned SC (Special Conservancy). Abutting properties include woodland and farmland on the north, south and east, and railroad tracks on the west. Site Use History U The Site is currently undeveloped, and based on historic aerial photographs and maps, does not appear to have been developed in the past. The northern portion of Lot 39- 031 historically had a dirt loop road which appears to have been used by farm equipment. The southwestern portion of Lot 39-040 appears to have had a small dirt race track on it. Portions of the property, particularly on the west side of the Mill River, appear to be informally used for hiking and camping. No known environmental conditions were identified on the Site or abutting properties. Current and past use of abutting properties include farmland and woodland, and railroad tracks. Page 6 O'Reilly, Talbot & Okun ~ [ A S S O C I A T E S] 1 Mapped Environmental Resources The Site is mapped as being within a medium yield aquifer. Based on this mapping, groundwater below the Site would be considered a Current or Potential Drinking Water Source Area as defined in 310 CMR 40.0006. Groundwater in the area is therefore classified as RC-GW1 for the purposes of release reporting under the MCP. MassGIS mapping indicates the entire Site lies within the 100 year floodplain, and a significant portion of the Site is freshwater wetlands. No certified vernal pools or Areas of Critical Environmental Concern are present on or within 500 feet of the Site. Site Reconnaissance No indication of a specific reportable release of oil or hazardous materials was observed on Site. However, the area does contain refuse on the ground surface, particularly in the northern portion of Lot 39-031. Old tires, abandoned farm equipment, a dumpster, broken furniture and other trash were observed. Coal ash/slag is present on the ground surface in at least one location. While these materials do not appear to be associated with a reportable release, their removal may be desirable for aesthetic reasons. 4.2 CONCLUSIONS AND RECOMMENDATIONS No reportable releases or potential impacts from known releases was identified at the Site. However, Lot 39-031 has been used as an informal disposal area. Materials present on the ground surface in that area include old tires, abandoned farm equipment, a dumpster, a cracked plastic tank, bricks, and at least one small pile of coal ash/slag. While exempt from release notification requirements pursuant to 310 CMR 40.0317, ash generally contains elevated levels of metals and PAHs. If ash or soils containing ash are removed from the property, the material should be managed under Bill of Lading and disposed of at a location where concentrations are not significantly lower than those in the excavated material, such that no degradation occurs at the receiving location. 5.0 LIMITATIONS Our Site Assessment was performed in accordance with generally accepted practices of other consultants undertaking similar studies at the same time and in the same geographic area. Our findings and conclusions must not be considered as scientific certainties, but rather as our professional opinion, concerning the potential significance of the limited data obtained during the course of our study. We do not and cannot represent that the Site contains no hazardous material or oil, or that the Site is free from latent conditions not observed in our assessment. Our report is subject to the additional Limitations contained in Appendix A. This assessment and report was prepared on behalf of and for the exclusive use of Client solely for rendering an opinion as to the presence of oil or hazardous materials in 7 O'Reilly, Talbot & Okun [ A S S O C I A T E S] 1 1 site soil and groundwater subject to requirements of M.G.L.

BRL Below Reporting Limit - Analyte NOT DETECTED at or above the reporting limit dry Sample results reported on a dry weight basis NR Not Reported RPD Relative Percent Difference A plus sign in the Method Reference column indicates the method is not accredited by NELAC. Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to document laboratory performance. Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix. Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix. Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank is used to document contamination resulting from the analytical process. Method Detection Limit (MDU The minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the analyte. Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest non-zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample RDLs are highly matrix-dependent. Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and samples prior to analysis. Percent recoveries are calculated for each surrogate. Validated by: Hanibal C.
