EXECUTIVE SUMMARY Cascade Earth Sciences (CES) has completed a Phase I Environmental Site Assessment (ESA) of the Former Morse Brothers Quarry; a 231-acre parcel located at 2903 Green River Road in Sweet Home, Oregon (Site). This ESA was performed in general accordance with the American Society for Testing and Materials (ASTM) Standard E 1527-05. Additional details regarding the scope, objectives, extent, and limitations of the services are described in the text. The Site is owned by Linn County as is located on 16 tax lots adjacent to the south and east of the South Santiam River. The Site was formerly used as a sand and gravel quarry and asphalt/concrete production facility. The Site is currently comprised of an unoccupied office building and shop; concrete foundations of former structures; aggregate, asphalt, and concrete piles; unpaved roadways; vegetated areas; and excavated ponds. Former industrial and residential properties and public roadways surround the Site. The Site was developed with agricultural land and residences as far back as 1936. A gravel pit was established on the southern section of the Site in the 1940’s. The gravel pit expanded from the 1940’s to early 1970’s and included quarrying operations by Albany Sand and Gravel Company along the western section of the Site near the South Santiam River. Morse Brothers, Inc. (MBI) acquired the Site through purchases of parcels in 1969, 1975, and 1985. In 1975, the permanent MBI asphalt plant and crusher was moved to the Site from Lebanon, Oregon. In about 1977, a machine shop and office were completed, and a concrete plant was operating on the eastern section of the Site. In about 1979, a cement-treated base plant was added west of the crusher. In 1985, 40 acres of property was acquired from Linn County north of the plant operations. By 1989, mining was occurring on the northwest section of the Site, and the conveyor system was relocated to access these materials. In 2003, Western States Land Reliance Trust (WSLRT) obtained the Site from MBI with the intent to develop the property. WSLRT reportedly defaulted on the Site and ownership reverted to Linn County. From 2007 to 2011, clean fill material was allowed to be imported to the Site from Liberty Rock Products. Weathered asphalt was reportedly also allowed for importation, provided the material was covered on one foot of cover and not in contact with groundwater. In March 2011, Linn County requested a cessation of importation of offsite materials. The Site has remained relatively unchanged since that time. The Site is identified on the Oregon Department of Environmental Quality (ODEQ) Environmental Cleanup Sites Inventory (ECSI) database in association with a spill of approximately 2,250 gallons of diesel fuel in 1998 (ECSI #2270). The spill was reportedly contained, delineated, and remediated. The ODEQ has proposed no further action for this diesel fuel spill, but has requested additional information regarding the possible nature and extent of contamination near the former asphalt plant before the file may be closed and a no further action letter can be submitted. To identify recognized environmental conditions, CES compiled and reviewed information obtained from a Site reconnaissance, historical inquiries, regulatory records review, environmental interviews/ questionnaires, and other reasonably ascertainable sources. Based on the foregoing assessment, there is no evidence of recognized environmental conditions in connection with the property except for the following:

 The Site remains an active facility on the ODEQ ECSI database (#2270) due to the potential for contamination from the former asphalt plant. Potential contaminants typically associated with asphalt plants may include petroleum hydrocarbons, metals, and solvents.  A former crusher and truck wash were located on tax lot 3101 at the Site. The disposition of the wash water from the truck wash is unknown, although based on Site observations and a review of historical aerial photographs, it likely percolated into the ground surface or drained to the northwest toward settling ponds. Wash water from the crusher was reportedly directed to settling ponds located to the north and northwest of the operation. No records were available for wash water quality from the crusher or sediment in the settling ponds, although wash water from crusher operations may be acidic.  Asphalt piles were observed on tax lots 2400, 3101, and 3805 at the Site. The piles were not covered, but did not appear to be buried in a manner that would result in contact with local groundwater.  Piles and spills of asphalt tar were noted across tax lots 3101 and 3805 at the Site. Evidence of runoff from the spill areas was observed trending to the northwest toward large excavated ponds.  An abandoned automobile, 55-gallon drums, car battery, and small containers of oil/power steering fluid were observed at the Site. These items were generally not stored properly or were exposed outside at the Site.  A former shop building is located at the Site. Based on a review of records, the shop was used from about 1977 to 2003. Petroleum products were used and stored inside the shop building, and truck repairs were likely performed onsite.  A small pit was noted inside the former shop during the Site visit. The pit was not thoroughly examined, although there did not appear to be any evidence of illicit discharge or releases.  A potential former aboveground storage tank (AST) was observed at the asphalt plant on a concrete base. The steel appeared to have been cut for salvage. A drain pipe that appears to have discharged to the ground surface was noted at the base of the concrete foundation.  Piping was observed cut at the ground surface just north of the diesel fuel secondary containment at the asphalt plant. The piping may have extended underground from the former ASTs.

 Tar spills on tax lots 3101 and 3805 should be excavated and removed from the Site. Surface soils stained black from runoff near the piles should be collected and analyzed for diesel fuel range hydrocarbons and SVOCs. The tar material should be disposed properly in a permitted facility.  The abandoned automobile, 55-gallon drums, car battery, and small containers of oil/fluids should be removed and disposed offsite.  Considering the former usage of the shop building at the Site, and the small pit inside the building, shallow soil samples should be collected. Samples should be analyzed for diesel fuel range hydrocarbons and metals.  A shallow soil sample should be collected from the soils at the base of the discharge pipe from the apparent former AST at the asphalt plant. Since the contents of the AST are unknown, the soil should be analyzed for the presence of petroleum hydrocarbons, metals, and VOCs.  Shallow soils samples should be collected near the apparent cut piping near the diesel fuel AST secondary containment. The samples should be analyzed for diesel fuel range hydrocarbons.

1.0 INTRODUCTION AND SCOPE OF SERVICES In accordance with our proposal dated September 19, 2011, Cascade Earth Sciences (CES) performed a Phase I Environmental Site Assessment (ESA) of the Former Morse Brothers Quarry, located at 2903 Green River Road in Sweet Home, Oregon (Site). Rick Partipilo, REHS, Linn County Environmental Program Manager, requested these services.

The intent of the ESA is to identify separate “recognized environmental conditions” in general accordance with the American Society for Testing and Materials (ASTM) Standard E1527-05 (ASTM, 2006). Recognized environmental conditions are defined under the ASTM standard as:

“... the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of release of any hazardous substances or petroleum products into structures on the property or into the ground, ground water or surface water of the property.”

The scope of this ESA was designed to assess potential environmental risk at the Site by reviewing available data and conducting a site reconnaissance. To complete this study, CES performed the following tasks: (1) historical use inquiries, (2) regulatory records search, and (3) site reconnaissance.

This report is not a comprehensive site characterization or regulatory compliance audit and should not be construed as such.

2.0 SITE DESCRIPTION 2.1 Location and Legal Description The Site is located adjacent to the south and east of the South Santiam River, and west of Clark Mill Road in an industrial and residential section of Sweet Home, Oregon. The Site is located on tax lots 901, 1000, 1400, 2300, 2400, 2600, 2701, 2800, 2900, 3000, 3100, 3101, 3800, and 3805 in Section 29, Township 13 south, Range 1 east of the Willamette Meridian, Linn County, Oregon. Based on the United States Geological Survey (USGS) 7.5 minute series topographic map of the area (Sweet Home Quadrangle), the latitude is 44°24'50.8" north and the longitude is 122°42’59.8" west (USGS, 1984). Figure 1, the Site Location Map, is a copy of the USGS map showing the location of the Site and surrounding features.

2.2 Site Characteristics Important features observed during the course of the reconnaissance are referenced in the following sections while selected photographs of the Site are included in Appendix A. Figure 2 shows approximate assessment boundaries, Site characteristics, and surrounding property features. Information regarding ASTM-recognized environmental conditions and any specific concerns is discussed in Sections 6.0 and 7.0.

2.2.1 Description of Site The Site is 231-acres and has the following features:  A 484 square-foot former office building (Photograph 1). The building is located south of the entrance road on tax lot 3805, adjacent to the north of former truck scales (Photograph 2).  A 988 square-foot former shop building (Photograph 3). This building is located north of the entrance road on tax lot 3101.  Concrete foundations of the former crusher plant buildings on tax lot 3101 (Photograph 4).  Concrete foundations of the former asphalt plant buildings on tax lot 3805 (Photograph 5).  Spoil piles near the former concrete ready mix plant on tax lot 3101.  Former diesel fuel aboveground storage tank (AST) secondary containment on tax lot 3805 (Photograph 6).  Former concrete ready mix plant on tax lot 3101 (Photograph 7).  Coarse and fine aggregate and asphalt piles on tax lots 2400, 3805, and 3101 (Photograph 8).  Piles of weathered concrete on tax lot 2800 (Photograph 9).  Excavated ponds on tax lots 901, 1000, 2800, 2900, 3000, and 3200 (Photograph 10).  The majority of the remainder of the Site is occupied by vegetation, spoil banks, and unpaved roads (Photograph 11).

2.2.2 Improvements and Utilities As previously mentioned, a 484 square-foot office building and a 988 square-foot shop building are located at the Site. The Site is currently not connected to electrical or natural gas service, although disconnected power poles on the ground near former concrete plant indicates PacifiCorp power was likely provided during quarrying and production operations. A domestic well, drilled in 1975, formerly provided potable water to the Site. A restroom was located inside the southeast corner of the machine shop building. As such, the Site was likely service by a septic system or cesspool during quarrying and production operations.

Stormwater generally drains toward the excavated ponds and swales located throughout the Site. Ponded water was observed at several locations near the former concrete and asphalt plants (Photograph 12). Surface drainage was also evident near tar piles throughout the Site (Photograph 13). Drainage was typically directed to the northwest toward the large excavated ponds.

2.2.3 Roads and Easements Zelkova (Green River) Avenue provides access to the Site from the east. A private driveway provides access to the Site from the northeast. Both access drives were locked at the time of the inspection. It is not known if easements are currently present for public utilities.

2.2.4 Zoning According to records on file with the City of Sweet Home Community Development Department, the Site is zoned RC (Recreational Commercial). Surrounding properties are primarily zoned for residential and industrial uses (City of Sweet Home, 2011).

2.3 Surrounding Property Characteristics Important features observed during the course of the reconnaissance are referenced in the following sections while selected photographs of surrounding properties are included in Appendix A. Information regarding ASTM-recognized environmental conditions and any specific concerns are discussed in Sections 6.0 and 7.0.

2.3.1 Northern Boundary The South Santiam River borders the Site to the north, beyond which, are residential properties (Photograph 14). No obvious potential environmental issues were noted during reconnaissance activities.

2.3.2 Southern Boundary The former Willamette Industries Mill property adjoins the Site to the south (Photograph 15). Lumber mill properties are typically associated with storage and use of regulated materials. However, the majority of the production appears to have been located approximately 0.25 miles south of the Site boundary. The property appeared to be fairly level with a slight slope to the west toward the South Santiam River.

2.3.3 Eastern Boundary Residential properties border the Site to the east (Photograph 16). The topography of these properties appears to be fairly level with a slight slope to the west toward the Site.

2.3.4 Western Boundary The South Santiam River is located adjacent to the west of the Site. No obvious potential environmental issues were noted during reconnaissance activities.

3.0 ENVIRONMENTAL SETTING Information provided in this section is useful for assessing the possible migration of potential contaminants originating onsite or from offsite sources.

3.1 Climate and Meteorology Climate and meteorology information was obtained from the Western Regional Climate Center, (WRCC, 2011). The climate of Sweet Home is characterized by warm, dry summers and cool, moist winters. The average maximum high and low temperatures occur in August at 80.7F and January with 33.7F. The area receives about 54 inches of precipitation annually with approximately 95% occurring between September and May. The general movement of air is from the west off the Pacific Ocean.

3.2 Physiography 3.2.1 Topography The Site is located on fairly level terrain at an elevation of approximately 515 feet above mean sea level (Figure 1; USGS, 1984). Regional topography trends to the north/northwest toward the South Santiam River. Evidence of flow patterns at the Site indicates surface drainage is generally to the northwest toward excavated ponds and the South Santiam River.

3.2.2 Soils The predominant soil types located at the Site are Fluvents-Fluvaquents Complex, pits, Newberg Fine Sandy Loam, and riverwash (USDA/NRCS, 1983). These are soils typically formed within floodplains, oxbows, overflow stream channels, sloughs, and bars. Parent material includes textured alluvium or alluvium from mixed sources. Soil permeability ranges from well-drained to poorly drained across the Site. It is important to note that soils in the upper profile at the Site may have been modified by development activities and information provided by the soil survey may be of limited value.

Test pits were completed at the Site by David Brown and Associates (DBA) as part of a geological and geotechnical investigation of the Site. According to the report, test pits generally contained solid packed cobbles/boulders (30-50%); coarse gravels (30-40%); and coarse sands (24-40%) (DBA, 1999).

3.2.3 Geology Sweet Home, Oregon is located at the eastern edge of the Willamette Valley physiographic province, an elongate alluvial plain of northwestern Oregon. Thick layers of Late Pleistocene and Holocene alluvium cover the majority of the valley floor. Older foundation rocks located in the Willamette Valley consist of volcanics that erupted as part of a submarine island archipelago. During the Pleistocene, breaching of enormous glacial lakes in Montana resulted in several large-scale floods, which deposited material throughout the province (Orr and Orr, 1999).

Surficial deposits in the Sweet Home area consist of gravels, sands, and some silts and clays. These deposits are designated as the “Younger Alluvium” and are generally greater than 50 feet deep along the Santiam River (USGS, 1977).

According to the DBA (1999) report, deposits at the Site were poorly sorted to non-sorted and poorly graded to non-graded. Fluvial reworking was apparent in the upper seven foot horizon , and the subrounded and subangular appearance of the cobbles indicated a glaciofluvial deposit.

3.3 Hydrology 3.3.1 Surface Water The nearest body of surface water is the easterly flowing South Santiam River, located adjacent to the north and west of the Site. In addition, excavated ponds are located across the northern section of the Site. Perennial sloughs and side channels of the South Santiam River are also located on the southwestern section of the Site.

3.3.2 Groundwater Based on a review of logs on file with the Oregon Water Resources Department (OWRD) for wells located near or at the Site, groundwater contact is estimated from about 4 to 27 feet below ground surface (OWRD, 2011; Appendix B). Fluctuations in this alluvial water table may occur seasonally in response to surface water recharge, precipitation, and irrigation pumping drawdown. The groundwater flow direction is expected to be to the northwest toward the South Santiam River, but may be influenced by depositional features associated with the area geology.

3.4 Unique Land Classification 3.4.1 Floodplain The Federal Emergency Management Agency (FEMA) determines flood hazard areas by conducting statistical analysis of river flow and precipitation data; gathering historical information, floodplain and hydrologic analysis and conducting public interviews. Sections of a river or stream channel and adjacent lands that are subject to floods with a one percent chance of being exceeded in any given year are identified as 100-year floodplains. FEMA flood data reviewed by Environmental Data Resources, Inc. (EDR) indicates that the Site is located within a 100-year flood hazard area (EDR, 2011a; Appendix D).

3.4.2 Wetlands Wetland delineation was beyond the scope of this ESA; however, according to the National Wetlands Inventory map for Sweet Home, Oregon, federally listed wetlands are located at the Site (EDR, 2011a). In addition, vegetation typically associated with wetlands (i.e., cattails) was observed during reconnaissance activities. Nonetheless, property owners are ultimately responsible for correctly designating, delineating, and reporting wetland boundaries if applicable areas exist on a property.

4.0 HISTORICAL USE INVESTIGATION CES obtained historical use information for the Site and adjoining properties by conducting interviews with persons knowledgeable of the Site and reviewing reasonably ascertainable historical sources such as ownership records, city directories, aerial photographs, and historical maps. Information from these sources may reveal past Site and adjoining property activities associated with the use, generation, storage, or disposal of hazardous/petroleum materials. The following sections summarize the information gathered from the historical use investigation.

4.1 Historical Interviews CES conducted interviews to obtain information pertinent to the historical use of the Site. During the Site visit, CES was escorted by Mr. Rick Partipilo, Program Manager for Linn County, Oregon. In addition, CES contacted Mr. Jeff Steyaert, Environmental/Land Permits Manager for Knife River Corporation in Tangent, Oregon.

Mr. Partipilo escorted CES personnel and provided access to the Site. He indicated a Phase I ESA had been performed at the Site, but was unavailable due to client confidentiality issues. Mr. Partipilo also stated Linn County had retained ownership of the Site following a default by the previous owner. He indicated Linn County was no longer accepting imported fill material to the Site until an agreement

Cascade Earth Sciences – Albany, OR Former Morse Brothers Quarry Phase I ESA PN: 2011230034 2903 Green River Road, Sweet Home, OR Doc: 2011230034 Linn County - Former Morse Brothers Quarry Phase I ESA (final).docm November 17, 2011 / Page 5 regarding reclamation can be reached with Morse Brothers, Inc. (MBI) and Knife River Corporation (Partipilo, 2011).

Mr. Steyaert indicated two underground storage tanks (USTs) were located adjacent to the west of the machine shop. The USTs were decommissioned and removed from the Site in about 1991. There was no evidence of contamination during removal, and analysis of four soil samples collected from the excavation and stockpiled soil did not identify a release of petroleum. Mr. Steyaert also stated all petroleum usage was aboveground following UST decommissioning at the Site. He did not recall any underground piping from the aboveground storage tanks (ASTs) at the asphalt plant. According to Mr. Steyaert, an insulated AST located near the former concrete plant was likely used for hot water storage.

Mr. Steyaert stated solvents were reportedly used until about 1990 at the asphalt plant at the Site. The solvent was used in the extraction process in the quality assurance laboratory to analyze asphalt content of mixtures. Used solvent materials was reportedly recycled at a facility in Corvallis, Oregon. Mr. Steyaert indicated to his knowledge, no illicit discharge or improper storage of solvents or solvent containers occurred at the Site (Steyaert, 2011).

4.2 Ownership Records The client neither provided nor requested a 50-year ownership history summary (Chain-of-Title) for inclusion in this report. According to the Linn County Assessor’s Office, the current owner of the Site is Linn County (Linn County, 2011a).

A review of available deed records to 1960 at the Linn County Clerk’s office indicates portions of the Site were owned by Albany Sand and Gravel Co., Willamette Industries, Linn County, and individuals that resided in dwellings at the Site. In 1965 and 1966, portions of the southeast section of the Site were sold by Murrell Gilkey, Carl Garnett, and Harold Rozell to Albany Sand and Gravel Co. In 1969, Albany Sand and Gravel Co. sold these parcels to MBI. In 1975, the northeast corner of the Site (tax lot 3200) was sold by Glenn Payne to MBI. In addition, the southern section of the Site (including tax lot 3805) was sold by Willamette Industries to MBI. In 1985, tax lot 2800 on the northern portion of the Site, was sold to MBI by Linn County. In 2003, the entire Site was sold by MBI to Western States Land Reliance Trust (WSLRT). The Site was reverted to Linn County in 2011, following a default by WSLRT (Linn County, 2011b).

4.3 Activity Use Limitations and Environmental Liens CES visited the Linn County Clerk’s office in Albany, Oregon to review available deed records associated with the Site. A review of these records did not identify any environmental liens at the Site (Linn County, 2011b). Moreover, the Site is not identified on the Oregon Department of Environmental Quality (ODEQ) Environmental Cleanup Site Information Database (ECSI), which identifies institutional controls on a state level (See Section 5.2). Furthermore, the EDR report did not identify any federal National Priorities List (NPL) Liens associated with the Site (EDR, 2011a).

4.4 City Directory Review City directories, which list businesses and residents with their addresses, can provide additional information regarding historical land use and development of a Site and surrounding area. CES visited the City of Albany Public Library in Albany, Oregon to review available city directories for the Site and surrounding properties (City of Albany, 2011). A summary of the review is provided below. Historic City Directories (Site) Year Address Occupant 1971 Clark Mill Road Morse Brothers 1980 Clark Mill Road Sweet Home Division, Morse Brothers, Inc. 1985 2903 Green River Road Sweet Home Sand and Gravel 1997 2903 Clark Mill Road Morse Brothers, Inc. 2000 2903 Green River Road Sweet Home Division, Morse Brothers, Inc. 2004 2903 Clark Mill Road Morse Brothers, Inc. Concrete Ready Mix

As shown, a sand and gravel/concrete business owned by MBI operated at the Site from at least 1971 to about 2004. Typical activities associated with quarrying operations include onsite fueling, vehicle repair, wash water discharge, and possible solvent use.

4.5 Aerial Photograph Review Aerial photographs can help establish prior land use and provide evidence of processes, facilities, or surface features that might be an indication of the storage or disposal of regulated materials. Evaluation of aerials is controlled by the photograph scale and quality. CES reviewed reasonably available aerial photographs depicting development of the Site and surrounding vicinity at periodic intervals (UO, 2011).

A total of 10 aerial photographs were available for review for the years 1936, 1939, 1947, 1952, 1961, 1970, 1979, 1982, 1994, and 2003. CES has summarized information from the review in the following paragraphs and provided copies of the photographs in Appendix C.

Date Description

The northern portion of the Site appears to be developed with residences and farmland. Clark Mill Road and Zelkova (Green River) Avenue are visible as access roads to the residences and farmland at the Site. The 1936 western section of the Site appears to be a floodplain of the South Santiam River. The remainder of the Site is undeveloped. The South Santiam River is visible adjacent to the north and west of the Site, beyond which, are forested areas and farmland. Farms and forestland are depicted south and east of the Site. The Site is relatively unchanged from the 1936 photograph, although additional clearing is evident for farmland. Properties located east and west of the Site also have been cleared of timber. Areas to the north of 1939 the Site are relatively unchanged from the 1936 photograph. Properties located south of the Site are relatively unchanged from the 1936 photograph, although two additional residences are visible along Clark Mill Road. An apparent quarrying operation is depicted on the southern section of the Site. Zelkova Road has been extended to the quarrying area. The South Santiam River channel has moved to the west and forms the current western boundary of the Site. The remainder of the Site appears to be relatively unchanged from the 1939 1947 photograph. Properties north of the Site are relatively unchanged from the 1939 photograph. The South Santiam River is visible west of the Site, beyond which, are residential developments. A mill log pond and residential developments are visible south of the Site. Areas east of the Site have residences, timberland, possible quarrying operations, and farmland.

Surrounding properties are relatively unchanged from the 1979 photograph. The majority of the Site is developed with quarrying and batch plant operations. The northeast corner of the 1994 Site is a large pond. Additional residential development is depicted to the west, north, and east of the Site. The majority of the Site is developed with quarrying and batch plant operations. Two ASTs are depicted at the southernmost plant in secondary containment. The northeast corner of the Site is a large pond. The northern 2003 section of the Site has large ponds. Drainage patterns are evident from the crusher to the northeast toward the large ponds. Surrounding properties are relatively unchanged from the 1994 photograph.

4.6 Historical Map Review 4.6.1 Sanborn Maps In the late nineteenth century, the Sanborn Company began preparing maps for use by fire insurance companies. These maps indicate construction materials of specific structures in developed urban areas. With the advent of retail gasoline service stations and related facilities, the locations of gas tanks were noted. These maps were periodically updated and expanded geographically through the twentieth century. According to EDR, which has acquired all of the Sanborn Company maps, no coverage exists for the Site (EDR 2011b; Appendix D).

4.6.2 Historic Topographical Maps CES reviewed the 1951 and 1984 7.5-minute series USGS topographic maps of the area (EDR, 2011c; Appendix D). A review of these maps is provided below: 1951: The Site is developed with gravel pits, buildings, and secondary roadways. Areas to the south are developed with apparent industrial properties and rail lines. Properties located north, east, and west of the Site include apparent residences.

1984: The Site and is developed with a gravel pit, buildings, and secondary roadways. Additional apparent industrial development is visible south of the Site. Additional residential development is depicted to the north, east, and west of the Site.

4.7 Additional Environmental Records 4.7.1 Oregon State Fire Marshal’s Records CES reviewed records from the Oregon State Fire Marshall’s (OSFM) database for hazardous materials incidents at the Site and surrounding properties. Based on a search of these records, no reportable incidents have occurred at or near the Site (OSFM, 2011).

4.7.2 Department of Geology and Mineral Industries Records CES visited the Oregon Department of Geology and Mineral Industries (DOGAMI) Mineral Land and Reclamation (MLRR) office in Albany, Oregon to review files associated with the Site. A review of available files indicated the first operating permit for MBI at the Site was issued in July 1970. The mining operation reportedly began at the Site prior to 1960. At the time, approximately 60,000 cubic yards of material were mined each year from the south and southwest portions of the Site.

In 1975, the permanent plant was moved to the Site from Lebanon, Oregon. The 1976 inspection report noted the settling pond used for the crushing plant was filled and a new pond was constructed to the north (Appendix E; Figure 3). DOGAMI aerial photographs of the Site identify concrete ready mix, asphalt plant, crusher, and cement-treated base (CTB) plant operations from 1979 to at least 1984. By 1985, wash water from the crushing plant was drained to the south through a series of beaver ponds. In May 1985, 40 additional acres of property was acquired from Linn County on the northern section of the Site (tax lot 2800). By 1989, mining was occurring on the northwest section of the Site, and the conveyor system was relocated to access these materials.

In 2003, WSLRT obtained the Site with the intent to develop the property. However, WSLRT defaulted on the property and Linn County retained ownership of the Site. In a June 2007 letter to WSLRT, the DOGAMI granted permission to transport clean fill material and weathered concrete to backfill areas at the Site as part of the reclamation permit. The letter also allowed importation of weathered asphalt, providing one foot of cover was placed over the material and it was not buried below the groundwater table (Appendix E). In 2011, Linn County requested a cessation of importation of fill material to the Site (DOGAMI, 2011).

CES also reviewed the DOGAMI Directory of Mineral Producers in Oregon listings from 1987 and 1993. The directories identified Morse Brothers Sand and Gravel as the occupant of the Site in 1987 and 1993 (DOGAMI; 1987, 1993).

4.7.3 Linn County Records The Linn County Assessor’s office provided CES with an assessment map of former operations at the Site. The map depicts the following (Appendix F):  A 988 square-foot shop building with compressor room and restrooms.  A 484 square-foot office building and truck scales.  Concrete plant with hoppers, water tank, scale hopper, control shelter, and truck loading.

 Asphalt plant with 800 square-foot secondary tank containment.  Crusher area and truck wash.

5.0 REGULATORY RECORDS REVIEW The purpose of reviewing reasonably ascertainable regulatory records is to identify recognized environmental conditions in connection with the Site. For this review, CES obtained primary records from EDR for federal, state, and EDR proprietary historical databases. CES has summarized pertinent information obtained from these databases in the following sections and included a copy of the EDR report in Appendix D.

The facilities identified are referenced as to their location relative to the apparent or published groundwater flow direction as defined below.  Upgradient indicates the listed facility appears to be at a higher groundwater elevation than the Site and contaminated groundwater, if present, would flow toward the Site.  Downgradient indicates the listed facility appears to be at a lower groundwater elevation than the Site and contaminated groundwater, if present, would not flow toward the Site.  Crossgradient indicates the Site and listed facility appear to be at approximately the same groundwater elevation and contaminated groundwater, if present, would likely not flow toward the Site.

UST The Site was identified on the UST database in association with two decommissioned USTs. There were no records of contamination indicative of a release from these former USTs. As such, they are not discussed further in this section.

OR CRL The former Plaza Dry Cleaners is the only CRL facility identified within the specified search radius. The property is located 0.813 miles southwest, in the apparent downgradient direction from the Site. Therefore, it is not considered a concern to this investigation.

5.3 Database Summary Based on the database information, the Site and adjacent former Willamette Industries property were identified by ODEQ requiring further assessment/investigation. Based on this, CES reviewed available files for both ECSI listings. A summary of the file review performed for the Site and adjacent property is presented in Section 5.6.

5.4 Unmappable Facilities The EDR report identified several unmappable facilities for the Sweet Home, Oregon area. Unmappable facilities are environmental risk facilities that EDR cannot map due to inadequate address information but can locate by zip code or city name. Based on a cursory review of area maps to assess distance from the Site, and additional regulatory records searches to determine the reasons for facility database listings, no unmappable facilities were identified near the Site.

5.5 Previous Site Investigations A Phase I ESA was reportedly completed for the Site in 2003. However, due to client confidentiality issues, the report was not released to CES for review.

5.6 Records Review 5.6.1 Site (ECSI #2270) The Site was identified on the ECSI database in association with a release of petroleum hydrocarbons from an AST system formerly located on tax lot 3805 at the asphalt plant. Based on a review of available records, approximately 2,250 gallons of diesel fuel was released in May 1998 when vandals broke a valve and opened the secondary containment for the ASTs. Spencer Environmental was contracted by MBI to recover free product. Petroleum contaminated soil (PCS) was also excavated within the spill area and stockpiled for disposal. A review of waste manifest indicates about 36.7 tons of PCS was disposed at Coffin Butte Landfill in Corvallis, Oregon.

In February 2002, confirmation soil samples were collected from the spill area. Results of the analyses identified low concentrations of diesel fuel (below cleanup standards) and heavy oil range hydrocarbons in the soil samples. As such, the ODEQ has recommended no further action for the diesel spill. However, the ECSI file will remain open due to the presence of the former asphalt plant and potential associated contamination. Based on this, and expanded preliminary assessment for the Site was recommended by ODEQ (Appendix E). The file also contained a reference to a complaint filed by a former employee of MBI. The complaint alleged drums of trichloroethene (TCE) were buried along the northern section of the Site near the South Santiam River. CES discussed this allegation with Mr. Steyaert, who stated the claim was without merit, and was probably the result of a false accusation from a disgruntled former employee of MBI.

5.6.2 Willamette Industries – Sweet Home (ECSI #347) The former Willamette Industries facility is located adjacent to the south of the Site (Photograph 13). A review of available records indicates several environmental investigations have been completed at the facility. In addition, in December 2005 and January 2006, soil was excavated and removed from the facility to address pentachlorophenol contamination in the spray booth area. Approximately 459 tons of soil was generated and disposed offsite as a result of the cleanup activities. Low concentrations of pentachlorophenol were left in place at the 5.5-foot excavation depth, which was considered beyond the zone of direct exposure. Furthermore, the cleanup report indicated monitoring wells located nearest the spray area have not been impacted by shallow pentachlorophenol soil contamination.

In 2008, the ODEQ provided a list of 10 potential source areas for further investigation. These include possible surficial releases and log pond sediments. Although additional investigation will be required at this facility, there does not appear to be any impact to shallow groundwater that would be indicative of possible offsite transport of contaminants to the Site. Considering this information, the former Willamette Industries Mill does not appear to pose an environmental threat to the Site.

6.0 SITE RECONNAISSANCE The objective of the site reconnaissance is to obtain information indicating the likelihood of ASTM- recognized environmental conditions in connection with the Site to the extent not obstructed by bodies of water, adjacent buildings, or other obstacles. Ryan Tobias of CES visually observed the Site and adjoining properties on October 24, 2011. Important features observed at the Site and/or surrounding properties in the course of completing the reconnaissance are referenced in the following sections while

Cascade Earth Sciences – Albany, OR Former Morse Brothers Quarry Phase I ESA PN: 2011230034 2903 Green River Road, Sweet Home, OR Doc: 2011230034 Linn County - Former Morse Brothers Quarry Phase I ESA (final).docm November 17, 2011 / Page 14 selected photographs are included in Appendix A. Section 7.0 includes a discussion of specific environmental concerns observed at the Site. Figure 2 shows approximate assessment boundaries, surrounding property features, and Site characteristics.

6.1 Site Observations CES observed a 484 square-foot office building and truck scales on tax lot 3805; a 988 square-foot machine shop building on tax lot 3101; aggregate and asphalt piles; foundations of former concrete and asphalt plant buildings; settling ponds/basins; large excavated ponds; truck loading areas; conveyor belts at the former crusher area; spoil banks, vegetation, and unpaved roads. None of the buildings or developed areas were in use at the time of the reconnaissance activities.

6.2 Adjoining Property Observations CES visually examined adjoining properties from legal boundaries or public access right-of-ways or by walking onto adjoining properties that were legally accessible. CES performed these observations to make a cursory assessment of current land use and the potential for recognized environmental conditions that may have affected or have the potential to affect the Site. The South Santiam River and residential areas border the Site to the north and west. A former lumber mill and log ponds are located adjacent to the south of the Site. Residences and paved roadways are located east of the Site.

7.0 FINDINGS AND OPINIONS The following subsections describe Site conditions and offer CES’ opinions regarding the impact or potential impact of these conditions on the Site.

7.1 Recognized Environmental Conditions To identify recognized environmental conditions, CES compiled the information obtained from the environmental interviews/questionnaires, records review, site reconnaissance, and, if applicable, other reasonably ascertainable sources. Recognized environmental conditions include, but are not limited to the following. Identified - Evidence of Impact to Environmental Condition Location Text Reference Site Regulated substances such as Potential impacts near petroleum products, pesticides, Yes – Section 7.1.1 Across developed areas of the Site former ASTs, shop solvents, corrosive wastes, etc. building Former asphalt plant and west Aboveground storage tanks Yes – Section 7.1.2 Potential surface impacts near concrete plant Underground storage tanks Yes – Section 7.1.3 Two decommissioned tanks None observed Physical indicators such as Evidence of runoff from odors, surficial staining, and Yes – Section 7.1.4 Staining from asphalt tar tar piles stressed vegetation Near former plant locations and Minor staining on ground Storage drums Yes – Section 7.1.5 machine shop surface Polychlorinated biphenyls Pole-mounted transformer east of (PCBs) (e.g., as contained in Yes – Section 7.1.6 None observed office building electrical transformers)

Identified - Evidence of Impact to Environmental Condition Location Text Reference Site Heating and cooling systems No Not applicable None observed Drains, dry wells, sumps, and Near restroom inside shop Yes– Section 7.1.7 None observed catch basins building Settling basins/ponds near former Pits, ponds, and lagoons Yes– Section 7.1.8 None observed plants Asphalt, tar, and concrete piles. Solid waste/debris Yes– Section 7.1.9 Staining from tar piles Refuse near former plants Wastewater/stormwater Probable septic tank. Stormwater Black staining from tar discharge (collection systems, Yes - Section 7.1.10 runoff from tar piles piles on-Site septic systems, etc.) On-Site wells Yes – Section 7.1.11 Domestic well located at the Site None observed While CES assessed the Site for all of the environmental conditions listed, the following sections detail only those conditions identified for the Site or surrounding properties.

7.1.1 Regulated Substances Diesel fuel was formerly stored at the Site in ASTs within a 25-foot by 32-foot secondary containment system. The ASTs have been removed from the Site and no current petroleum storage was observed onsite. The majority of the piping for the ASTs was likely aboveground, although evidence of underground piping cut at the ground surface, adjacent to the containment, was noted during reconnaissance activities (Photograph 18). The condition of the underground piping is unknown, and should be further investigated.

Evidence of petroleum usage was observed inside and adjacent to the compressor room in the former machine shop during the site reconnaissance (Photograph 19). Moreover, staining was observed inside the main working area of the shop building on the concrete slab flooring (Photographs 20 and 21). There was no evidence of direct impacts to the ground surface from petroleum use in the compressor room.

Small containers of motor oil and power steering fluid were observed in the shop building during the site reconnaissance (Photograph 22). In general, these small containers did not appear to pose a significant environmental risk to the Site.

A used automobile battery was observed on the ground east of the shop building during the site reconnaissance (Photograph 23). There was no indication of a release from this battery that may have adversely impacted the Site. However, the battery should be removed and disposed/recycled properly to prevent a release of corrosive materials to the ground surface.

According to Mr. Steyaert, solvents were used at the Site prior to 1990 in the quality assurance laboratory to analyze asphalt content in mixtures. There were no indications of solvent storage or usage noted during reconnaissance activities at the Site. However, near surface soil/groundwater samples should be collected near the former laboratory area to confirm this assumption.

An abandoned vehicle was present adjacent to the east of the office building during the site reconnaissance (Photograph 1). The vehicle is exposed to rainfall and should be removed from the Site to prevent a release of petroleum hydrocarbons or automobile fluids to the Site.

7.1.2 Aboveground Storage Tanks As discussed in Section 7.1.1, evidence of two former ASTs was noted inside secondary containment on tax lot 3805 at the Site. In addition, an AST was noted north of the former concrete plant on tax lot 3101 (Photograph 24). The AST appeared to be insulated (Photograph 25) and, according to Mr. Steyaert, was probably used to store hot water for concrete processing. A discharge pipe was noted at the base of the AST, adjacent to insulation material on the ground (Photograph 26). Considering the use of the AST to store water, it is not likely a concern to this investigation. However, if the AST is removed from the Site, the insulation material may need to be sampled for asbestos content.

Another possible former AST was observed at the asphalt plant during the Site visit. The steel was cut and concrete base of the former AST was evident (Photograph 27). A discharge pipe was noted at the base of the concrete foundation. There was no evidence of a release, although the contents of the possible former AST are unknown. Soil sampling near the discharge area may be warranted to identify a possible release from the possible former AST.

7.1.3 Underground Storage Tanks There were no indications of vent pipes or fill ports observed at the Site during reconnaissance activities. A total of two USTs were reportedly located adjacent to the shop building, but were decommissioned and removed in 1991. According to Mr. Steyaert, no soil contamination was encountered during decommissioning activities.

7.1.4 Physical Indicators Surficial staining was observed near tar piles located on tax lots 3101 and 3805 (Photographs 28, 29 and 30). Evidence of stormwater runoff and staining from the piles was also observed (Photograph 13). Based on this, the tar piles should be removed from the Site and disposed properly. Stained soils from tar pile runoff should also be sampled and analyzed to identify possible impacts from stormwater.

7.1.5 Storage Drums Storage drums were observed on tax lots 3101 and 3805 at the Site. An empty calcium chloride drum was observed near the former crusher on tax lot 3101 (Photograph 31). The calcium chloride may have been used as an additive to the concrete mixture as an accelerator. There did not appear to be any impacts to the ground surface from the empty drum and therefore, it should not be considered a concern to this investigation.

A 55-gallon drum, likely used to store petroleum, was observed on tax lot 3805 near the former asphalt plant (Photograph 32). The drum was stored on a concrete pad and did not appear to have adversely impacted the surrounding surface soils. The drum appeared to be full, and was not watertight (Photograph 33). Therefore, there is a potential for overflow of oily water during heavy rainfall events. As such, this drum should be removed from the Site and properly disposed.

A 55-gallon drum, likely used to store tar, was observed south of the shop building during the site reconnaissance (Photograph 3). The drum was empty, although some tar residue was noted on the inside

Cascade Earth Sciences – Albany, OR Former Morse Brothers Quarry Phase I ESA PN: 2011230034 2903 Green River Road, Sweet Home, OR Doc: 2011230034 Linn County - Former Morse Brothers Quarry Phase I ESA (final).docm November 17, 2011 / Page 17 the container. The drum does not appear to pose a significant environmental threat to the Site, although it should be removed and properly disposed.

An empty 55-gallon drum was observed northeast of the office building during reconnaissance activities (Photograph 34). The drum was stored on a paved surface and did not appear to have adversely affected the Site. Therefore, is not considered a concern to this investigation.

7.1.6 Polychlorinated Biphenyls Electrical transformers may pose an environmental risk due to the possible presence of polychlorinated biphenyls (PCBs) in the transformers' dielectric fluid. A pole-mounted transformer was observed on the eastern section of the Site near the entrance to the office and scales (Photograph 35). The transformer is likely owned by PacifiCorp. There were no stickers observed on the transformer indicating it does not contain PCBs. However, there were no indications of leaks or spills that may have adversely affected the Site. The transformer is the responsibility of the local power company and, thus, removal and/or cleanup would be their responsibility. Based on the lack of evidence of any potential spills or leaks, the pole-mounted transformer is not considered to be a significant threat for PCB contamination.

No other transformers were observed during reconnaissance activities at the Site. Power poles likely used during operation of the quarry were noted on the ground near the former crusher (Photograph 36). There were no indications of transformers near the power poles.

7.1.7 Drains, Dry Wells, Sumps, Catch Basins There were no drains observed inside the shop building during reconnaissance activities. A small pit was observed near the restroom area, on the eastern edge of the shop building (Photograph 37). The purpose of the pit is unknown. However, considering the use of oil and evidence of staining inside the building, further investigation of surface soils at the bottom of the pit may be warranted.

7.1.8 Pits, Ponds, and Lagoons Large excavated ponds are located on the northern and northwestern sections of the Site. Ponded water was also observed near former operations at the asphalt plant and crusher (Photograph 12). Drainage patterns are generally to the northwest toward the large ponds at the Site. Historic records also indicate settling ponds for the crusher/truck wash were located north and northwest of the most recent operations on tax lot 3101 (Appendix E; Figure 3). Furthermore, the 2003 aerial photograph depicts drainage patterns from the crusher to the northwest toward the ponds. Based on these observations, further assessment is warranted in these areas of the Site.

7.1.9 Solid Waste/Debris Piles of spoils banks, aggregate material, weathered concrete, and asphalt were observed throughout the Site during reconnaissance activities. Spoil banks generally appeared to be native material excavated and casted at the Site. Aggregate material was observed near the former crushing and plant operations at the Site. Weathered concrete was visible along the northern bank of the large excavated ponds on the northern section of the Site (Photograph 9). Tire ruts neat the bank of the excavated ponds indicate the material was recently imported to the Site.

Asphalt piles were present on tax lot lots 2400, 3805, and 3101 (Photograph 8). According to the DOGAMI letter to the former Site owner in June 2007, weathered asphalt could be imported to the Site, if properly managed. This included a one foot cover over the asphalt and no contact with local groundwater. The asphalt piles at the Site were not covered during the reconnaissance activities (Photograph 38). As such, there is a potential for runoff of petroleum hydrocarbons during rainfall events.

7.1.10 Wastewater/Stormwater Discharge The Site shop building reportedly has a septic system and drainfield for the restroom. There was no evidence of illicit discharge to the septic system during the Site visit.

Stormwater at the Site is generally directed to the northwest toward excavated ponds, or appears to percolate into the ground. There was no evidence of dry wells or catch basins at the Site.

Runoff and wash water generated near asphalt plants and truck washes may contain oil and grease, solvents, and metals. Based on the observations of surficial staining near the former crusher, it is also possible near-surface soils may contain petroleum hydrocarbons from runoff during rainfall events.

7.1.11 Private or Municipal Water Wells The Site reportedly has a domestic water well, originally drilled in 1975. The well was not observed at the Site during reconnaissance activities.

7.2 Non Scope Considerations Non-scope considerations such as asbestos-containing materials (ACM) and lead-based paint (LBP) may be assessed during the ESA process but are not required as part of the ASTM standard practice. A full assessment of these materials was not included in this investigation. However, based on the date of construction and operations, the Site buildings could have asbestos and lead-paint.

8.0 DATA GAPS Data failures occur when all of the standard historical sources that are reasonably ascertainable and likely to be useful have been reviewed and yet, the objectives have not been met. No data gaps were encountered during the course of this investigation.

9.0 CONCLUSIONS AND RECOMMENDATIONS CES has performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM Practice E 1527 of the Site located at 2200 West 6th Avenue in Sweet Home, Oregon. Any exceptions to, or deletions from, this practice are described in Section 1.0 of this report. This assessment has revealed no evidence of recognized environmental conditions in connection with the property, except for the following

 The Site remains an active facility on the ODEQ ECSI database (#2270) due to the potential for contamination from the former asphalt plant. Potential contaminants typically associated with asphalt plants may include petroleum hydrocarbons, metals, and solvents.  A former crusher and truck wash were located on tax lot 3101 at the Site. The disposition of the wash water from the truck wash is unknown, although based on Site observations and a review of historical aerial photographs, it likely percolated into the ground surface or drained to the northwest toward settling ponds. Wash water from the crusher was reportedly directed to settling ponds located to the north and northwest of the operation. No records were available for wash water quality from the crusher or sediment in the settling ponds, although wash water from crusher operations may be acidic.  Asphalt piles were observed on tax lots 2400, 3101, and 3805 at the Site. The piles were not covered, but did not appear to be buried in a manner that would result in contact with local groundwater.  Piles and spills of asphalt tar were noted across tax lots 3101 and 3805 at the Site. Evidence of runoff from the spill areas was observed trending to the northwest toward large excavated ponds.  An abandoned automobile, 55-gallon drums, car battery, and small containers of oil/power steering fluid were observed at the Site. These items were generally not stored properly or were exposed outside at the Site.  A former shop building is located at the Site. Based on a review of records, the shop was used from about 1977 to 2003. Petroleum products were used and stored inside the shop building, and truck repairs were likely performed onsite.  A small pit was noted inside the former shop during the Site visit. The pit was not thoroughly examined, although there did not appear to be any evidence of illicit discharge or releases.  A potential former AST was observed at the asphalt plant on a concrete base. The steel appeared to have been cut for salvage. A drain pipe that appears to have discharged to the ground surface was noted at the base of the concrete foundation.  Piping was observed cut at the ground surface just north of the diesel fuel secondary containment at the asphalt plant. The piping may have extended underground from the former ASTs.

Based on these findings, CES recommends the following:  Shallow soils/groundwater near the former asphalt plant should be collected. Samples should be analyzed for the presence of diesel fuel range hydrocarbons, volatile organic compounds (VOCs) (including solvents), metals, and semi-volatile organic compounds (SVOCs).  Shallow soils/groundwater near the former truck wash should be collected. Samples should be analyzed for diesel fuel range hydrocarbons, metals, VOCs, and SVOCs.  Sediment in the former crusher/truck wash settling ponds should be excavated and collected. Samples should be analyzed for diesel fuel range hydrocarbons and metals.  Asphalt piles should be managed in accordance with the June 2007 DOGAMI letter, which directs one foot of clean cover material be placed on the piles and no direct contact with local groundwater.  Tar spills on tax lots 3101 and 3805 should be excavated and removed from the Site. Surface soils stained black from runoff near the piles should be collected and analyzed for diesel fuel range hydrocarbons and SVOCs. The tar material should be disposed properly in a permitted facility.  The abandoned automobile, 55-gallon drums, car battery, and small containers of oil/fluids should be removed and disposed offsite.  Considering the former usage of the shop building at the Site, and the small pit inside the building, shallow soil samples should be collected. Samples should be analyzed for diesel fuel range hydrocarbons and metals.  A shallow soil sample should be collected from the soils at the base of the discharge pipe from the apparent former AST at the asphalt plant. Since the contents of the AST are unknown, the soil should be analyzed for the presence of petroleum hydrocarbons, metals, and VOCs.  Shallow soils samples should be collected near the apparent cut piping near the diesel fuel AST secondary containment. The samples should be analyzed for diesel fuel range hydrocarbons.

SURROUNDING SITES: SEARCH RESULTS Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property. Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

WILLAMETTE INDUSTRIES - SWEET HOME (Continued) S110072087 asbestos-containing debris from the former Willamette Industries sawmill property at 2210 Tamarack in Sweet Home. The 153-acre site is owned by Western States Land Reliance Trust. Demolition of the old mill began in 2007 but ended after large quantities of asbestos-containing materials were found. Piles of mostly uncovered materials have remained within yards of numerous houses, reporter Alex Paul reports. EPA project coordinator Dan Heister said the cleanup took one day less than expected and came in slightly above budget at $1.1 million. EPA bore the cost and will seek reimbursement from the trust.

These soils are generally located at a depth of approximately 4 to 10 feet bgs and are overlain by uncontaminated soils. Based on the results of July 2005 groundwater monitoring events, if site groundwater has been affected by contaminants of potential concern identified in soil, the affects appear to be limited to the area directly beneath the impacted soils and do not appear to be migrating from those areas

The soil excavation efforts were focused on the western side of the truck shop where total petroleum hydrocarbons (TPH) had been detected in excess of 10,000 milligrams per kilogram (mg/kg). Due to physical constraints including existing structures (truck shop building, and an overhead hoist/truck-trailer lift and associated control shed), affected soil immediately adjacent to and beneath these features was left in place.

The site was most recently operated as a service and maintenance f acility for logging trucks (Wimer Logging Truck Shop) until approximately 2001.

The following presents a summary of site history based on our aerial photo review. From 1936 to 1939 the site was vacant and undeveloped as were the adjacent properties to the east, south, and west. What are now 24th Avenue and Highway 20, and the railroad (RR) tracks along the north site boundary were present at their current locations. A lumber mill and log pond were located north of the site and RR tracks. From sometime between 1939 and 1947 until sometime between 1970 an d 1982 the northern portion of the site was occupied by a log pond.

Several areas of surface staining were noted. Soil analysis indicated the presence of diesel range petroleum hydrocarbons from the surface (2000 ppm) to a depth of 15 feet (14.7 ppm). Further site reconnaissance was conducted during 7/93 to locate additional areas of contamination. Site cleanup activities included excavation of about 45 cubic yards of contaminated soil from several different areas and disposal at Hillsboro Landfill. None of the excavated areas were tested for the presence of PCBs or volatiles. All of the samples analyzed had detectable levels of TPH. However, qualitative identification of the contamination was not performed.

The removal locations for PCB- and 1,4-dichlorobenzene-contaminated soils are unknown. Therefore, additional environmental testing is needed to properly characterize the source, location, and extent of on-site contamination. DEQ has referred this site to EPA/TSCA because soil analytical results indicate a release of PCBs.

Analyses of shallow groundwater samples from the six borings showed the presence of PCE, a dry-cleaning solvent. The highest concentrations were detected north of the space formerly occupied by the dry cleaner. the building housing dry cleaners was demolished in December 2001. The owners of the shopping center applied to DEQs Voluntary Cleanup Program (December 2001) and its Dry Cleaner Program (March 2002). The site was accepted into the Dry Cleaner Program in April 2002. (9/11/06/DEH/DC) DEQ’s Dry Cleaner Program conducted a focused sit e investigation in October 2005. Ninteen soil and 12 grab groundwater samples were collected using a Geoprobe direct push rig. A mobile laboratory was used to analyze most of the samples, however a fixed laboratory was used for QC purposes and some of the follow up analyses. perchloroethylene (PCE or perc) was the primary contaminant identified in the investigation, however small amounts of trichloroethylene (TCE) and cis-1,2-dichloroethylene (cis-DCE) were also detected in a few of the soil samples and in the groundwater samples. The greatest concentration of PCE detected was 7.7 mg/kg. The greatest concentration of PCE in groundwater was 11,000 ug/L. A plume of contaminated groundwater was identified trailing to the northwest from the site, in a direction that conicides with groundwater flow directions seen at other cleanup sites in Sweet Home. Sampling of nearby residential drinking water and irrigation wells has determined that the contamination has not contaminated private wells at this time. Remediation conducted in 2006 should greatly reduce the threat of off-site groundwater contamination in the future.

Based on the distrubution of contamination north of the former cleaners, it appears that the releases may have been from materials placed on the ground out the back door of the cleaners, or possibly by leaks in sanitary sewer piping leading from the cleaners to the sewer main. There does not appear to be much if any contamination directly beneath the former cleaner’s concrete slab, based on investigations conducted in 2005.

NARR ID: 5742055 NARR Code: Pathways Other Hazards Created By: Not reported Created Date: 12/17/2002 Updated By: GWISTAR Updated Date: 03/27/2003 NARR Comments:The site is in central Sweet Home. The surrounding area appears to be a mix of industrial, commercial, and residential properties. Sweet Home High School is 700 ft SSE of the site. The nearest surface water is a log pond about 700 feet north of the site. The South Santiam River is about 0.5 mile north of the site. Observations made in the summer of 2001 indicate that shallow groundwater occurs between 9 ft and 15 ft bgs. Based on DEQ’s Areawide Groundwater Investigation (May 2000), the direction of groundwater flow is interpreted to be NNW toward the river. Four domestic wells, including two used for drinking water, are located between the site and the river. The nearest drinking water well is 340 feet north of the former dry cleaner. The two nearest wells were sampled in February 2003; no dry-cleaning chemicals or other VOCs were detected in either well.

NARR ID: 5746249 NARR Code: Remedial Action Created By: NSAWKA Created Date: 02/08/2005 Updated By: GWISTAR Updated Date: 01/12/2007 NARR Comments:(2-8-05/NS/CU) The property owner’s conducted a Phase II Environmental Site Assessment in June 2001. Based on the assessment, chlorinated solvents were found in the soil and groundwater beneath the site. The highest concentrations were found just north of the former dry cleaner building (in the probable downgradient location). PCE and TCE in the soil boring north of the dry cleaners were detected at 4,050 mg/kg and 0.085 mg/kg, respectively. PCE and TCE levels in the groundwater of the same boring were 62,000 ug/L and 545 ug/L. The site joined the VCP program in December 2001 and completed a groundwater beneficial use study and sampling of select groundwater use wells. At least 4 existing domestic wells were identified between the site and the Santiam River within a 1/4 mile and downgradient. Two of the identified wells were used for drinking water purposes and two for irrigation. Two of the closest wells were sampled in February 2003. VOCs were not detected in either well. The area is serviced by a municipal water supply source. The site was accepted into the dry cleaner program in April 2002. At the time, the former dry cleaner and the adjacent connected buildings had been vacated and demolished. The site requires additional characterization work to completely define the extent of the soil and groundwater plumes and the LOF. No immediate threats were identified during a file review of the site by the dry cleaner PM, except for a potential future threat to the four domestic downgradient wells.

PLAZA DRY CLEANERS (FORMER) (Continued) S105710725 (7/27/05/NS/DC) The dry cleaner and adjacent buildings have been d emolished. The owner is planning on redeveloping the shopping center in coming years. Demolition activities and present a good opportunity for DEQ to start SI and IRAM work at the site before the new shopping center goes in. Funds have been allotted from the Dry Cleaner Program to conduct this work. (9/11/06/DEH/DC) DEQ’s Dry Cleaner Program conducted a focused sit e investigation at the site in October 2005, collecting numerous subsurface soil and shallow groundwater samples from the site, and utilizing a mobile chemical analytical laboratory. This investigation identified a hot spot of contamination in soil north of the former dry cleaner, as well as a groundwater contaminant plume trailing to the northwest from the soil hot spot. The contamination consists primarily of PC, with few breakdown/daughter products such as TCE or cis-DCE. In August 2006, DEQ’s Dry Cleaner Program initiated remediation at the site. Approximately 300 cubic yards of PCE contaminated soil were excavated. The soil was placed in a treatment cell where vacuum extraction will remove PCE and TCE vapors from the soil. The contaminants in the vapors will be contained in granular activated carbon. The excavation was backfilled with gravel; however injection piping was first placed within the excavation. This piping will allow introduction of remediation products into the subsurface at the source area. Groundwater extraction and injection wells were installed downgradient and upgradient of the contaminant source area in August 2006. Also in August, DEQ’s contractors initiated groundwater treatment consisting of dosing the recirculation water with dextrose and nutrients to help stimulate natural biodegradation of the PCE. The amended water is injected upgradient at the injection well, and at the source area (former soil excavation injection piping). The dextrose injection work is completed by Enzyme Technologies, Inc. under subcontract to DEQ’s general contractor Hart Crowser. It is anticipated that the soil and groundwater remediation systems will operate for about 6 months.

PLAZA DRY CLEANERS (FORMER) (Continued) S105710725 NARR Comments:(12/17/10 DEH) Plaza Dry Cleaners operated at the Santiam Plaza shopping center in Sweet Home from 1971 to 2001, when it was closed and the building was razed. Dry cleaning solvent (tetrachloroethylene or PCE) contamination was detected in the soil and groundwater beneath the site in 2001 by the property owner. In April 2002 the site was accepted into the DEQ Dry Cleaner Program. DEQ conducted a focused site investigation in 2005 and in 2006 began cleaning up the soil (excavation) and groundwater (bioremediation) at the site. Groundwater cleanup continued until November 2007. Groundwater treatment has removed much of the PCE from the site. DEQ continues to monitor the groundwater concentrations on site, as well as downgradient groundwater receptors to see if any further cleanup actions will be needed.

EDR Proprietary Records

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants) compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

EDR’s GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in forming an opinion about the impact of potential contaminant migration.

Assessment of the impact of contaminant migration generally has two principle investigative components:

1. Groundwater flow direction, and 2. Groundwater flow velocity.

Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata.

TC3193472.2s Page A-1 GEOCHECK® - PHYSICAL SETTING SOURCE SUMMARY

GROUNDWATER FLOW DIRECTION INFORMATION Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site-specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers).

TOPOGRAPHIC INFORMATION Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

GROUNDWATER FLOW VELOCITY INFORMATION Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil characteristics data collected on nearby properties and regional soil information. In general, contaminant plumes move more quickly through sandy-gravelly types of soils than silty-clayey types of soils.

GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring.
