Phase II ESA Report – Knife River Property City of Kalispell November 2011 2 EXECUTIVE SUMMARY AMEC Geomatrix, Inc. (AMEC) completed a Phase II Environmental Site Assessment (ESA) of several contiguous parcels owned by the Knife River Corporation (KRC) in Flathead County, Montana. The Phase II ESA evaluated potential environmental impacts associated with recognized environmental conditions (RECs) and potential contaminant sources identified during the 2011 Phase I ESA and historic uses of the property and adjacent properties. Assessment of the property (hereafter called the “Site”) was conducted in accordance with ASTM standards and 42 USC §9601 (35) The purpose of the ESA was to assess environmental impacts in anticipation of property sale and/or reuse. AMEC investigated the following potential contaminant sources during this ESA:  Contaminants of concern that may have migrated via groundwater flow onto the Site from the adjacent KRY State CECRA (Superfund) Facility;  Petroleum hydrocarbons originating near the onsite Truck Repair Shop;  Exterior sump at the Truck Repair Shop;  Asbestos and Lead-Based Paint associated with onsite structures; and  An onsite plastic-lined pit. Groundwater Impacts from the CECRA Facility Contaminants have migrated in groundwater onto the Site from the adjacent KRY Facility. In general, concentrations of contaminants in groundwater samples collected on the eastern portion of the Site in 2011 (adjacent to the CECRA Facility) were similar to or lower than historic concentrations. Pentachlorophenol (PCP) and dioxin concentrations in the sampled monitoring wells were below Montana Department of Environmental Quality (DEQ) risk-based screening levels and/or numeric groundwater quality standards. Dioxin concentrations were either similar to or lower than the most recent historical samples collected from the monitoring wells. Petroleum hydrocarbons, iron, and manganese were not detected in groundwater above water quality standards. AMEC was unable to obtain groundwater samples from two of the onsite monitoring wells proposed for sampling in the EPA–approved SAP. One of the wells contained free product and an obstruction in the casing was encountered in the second well. We do not recommend additional groundwater investigation or sampling at this time. Soil at the Truck Repair Shop AMEC documented petroleum hydrocarbon contamination in three test pits completed on the northwest side of the Truck Repair Shop. The surficial waste-oil source sample contained methylene chloride at a concentration that exceeded the EPA generic soil screening level protective of the leaching to groundwater pathway. The source sample also contained C9-C18 aliphatic hydrocarbons at a concentration that exceeded the residential surface soil DEQ Tier 1 RBSL. Concentrations of C9-C18 aliphatic hydrocarbons; however, were below DEQ Tier 1 protective of commercial exposure. Methylene chloride and C9- C18 aliphatic hydrocarbon concentrations in subsurface test-pit soil samples (depths of 2.5-4 feet) were also below EPA and DEQ screening levels, suggesting that the depth of soil contamination is limited. At a test pit excavated laterally from the source area, concentrations of C9-C18 aliphatic hydrocarbons and C11-C22 aromatic hydrocarbons exceeded their respective residential Tier 1 in surface soil but were below ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 3 residential and commercial at a depth of 2.5 feet bgs. AMEC recommends shallow excavation and offsite disposal of soils along the northwest side of the Truck Repair Shop to eliminate exposure risks associated with direct contact to the soil or ingestion of contaminants that may leach to groundwater. Truck Repair Shop Sump AMEC inspected the sump and collected a sediment sample from the sump structure. The sump has a concrete bottom and sides. Water and sediment in the sump prevented a thorough inspection of the concrete; however, the sump appeared to be intact. Concentrations of several volatile organic compounds in the sediment sample exceeded EPA leaching to groundwater generic soil screening levels. Concentrations of C9-C18 aliphatic hydrocarbons and C11-C22 aromatic hydrocarbons also exceeded the residential surface soil Tier 1 however, concentrations were below commercial Based on the above information, we recommend removal and disposal of the sump contents. Closure of the sump should be considered as it represents a potential source of contamination to underlying soil and groundwater. Asbestos and Lead-Based Paint Five onsite buildings were inspected and sampled to evaluate the presence of asbestos containing building materials (ACBM). Three building materials were determined to be ACBMs: mastic in the scale office; roofing/silver paint in the main shop; and window glazing in the tire shop. Sampling for lead-based paint (LBP) was completed to evaluate the lead content of anticipated waste streams if one or more buildings were to be demolished. Waste stream lead concentrations were below the regulatory standard of 5.0 mg/L lead for four of the five buildings. The waste stream concentration at the tire shop was 5.6 mg/L, largely due to lead in the structure’s exterior painted siding. AMEC recommends the removal of ACBMs at the time the building(s) are demolished and/or renovated. Abatement of the asbestos will require special considerations for handling and containerization prior to demolition. The Flathead County Landfill will accept such materials provided they are appropriately containerized and transported. Special considerations for lead abatement are required prior to demolition of the Tire Shop. The principal work required consists of removal of the exterior painted siding or paint on the siding prior to demolition of the building and appropriate disposal of the lead-based paint. Plastic-Lined Pit AMEC collected three five-point composite samples of soil within the pit to document the presence/absence of potential contaminants of concern. Concentrations of all contaminants of potential concern were below applicable EPA and DEQ generic soil screening levels. AMEC does not recommend any additional investigation or remediation of soils located within the lined pit. Cleanup Costs The estimated cost to implementation of the above recommendations is estimated to cost approximately $28,000. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 4 1.0 INTRODUCTION AMEC Geomatrix, Inc. (AMEC) completed a Phase II Environmental Site Assessment (ESA) of several contiguous parcels owned by the Knife River Corporation (KRC) in Flathead County, Montana (Figure The property investigated is located west of U.S. Highway 93 and immediately north of the Kalispell city limit (Figure The Phase II ESA evaluated potential environmental impacts associated with recognized environmental conditions (RECs) identified during the Phase I ESA (AMEC 2011a) and historic uses of the property and adjacent properties. Assessment of the property (hereafter called the “Site”) was conducted in accordance with ASTM standards and 42 USC §9601 (35) The purpose of the ESA was to assess environmental impacts in anticipation of property sale and/or reuse. This report documents the methods and results of the assessment, and provides conclusions and recommendations with regard to additional assessment and site remediation based on anticipated property redevelopment. AMEC completed the assessment using EPA community-wide hazardous substance grant funds. The assessment was completed in accordance with the Phase II Sampling and Analysis Plan (SAP) approved by EPA and DEQ in September 2011 (AMEC 2011a). The SAP was initially approved by the EPA, and then later by the DEQ (Appendix DEQ approval of the plan was required because soil and groundwater sampling within the boundary for the KRY Montana Comprehensive Environmental Cleanup Responsibility Act (CECRA) facility was deemed a remedial action. AMEC provided the City of Kalispell with preliminary results of the assessment in a letter dated October 14, 2011 (AMEC 2011b). 1.1 Background and Site Description The Site is located in an area of mixed commercial, residential and heavy industrial land uses (Figure The Stillwater River and Whitefish Stage Road are located near the western and northwestern Site boundaries, and the Burlington Northern Railroad and Flathead Drive are located near the eastern boundary. The Site comprises several parcels of land, all owned by Knife River Corporation (KRC). Although the Site is located just outside of the Kalispell city limit, KRC has signed a waiver of the right to protest annexation. Several properties near and adjacent to the Site, as well as a portion of the Site, are part of a Montana (CECRA) site known as the KRY Facility (See Section 2.1). The Site consists of seven contiguous parcels of land that total 56.6 acres. The legal description of the Site is Tracts 1 through 7, Certificate of Survey No. 18380, Flathead County, Montana. Approximately 15.9 acres of Tract 1 is located on the west side of Whitefish Stage Road within the floodplain of the Stillwater River. This portion of the KRC property, which contains undeveloped forested areas, wetlands, and a riparian area, was not part of the environmental assessment. The remaining 40.7 acres (the focus of this assessment) is located on the east side of Whitefish Stage Road, and is a former gravel mining operation that contains an inactive concrete batch plant, an active truck repair shop and a storage facility (Figure KRC leases a portion of the Site to Butch Barber Trucking, which operates the repair shop and stores equipment in a nearby Quonset hut. Although the area of the Site investigated is generally flat, past gravel-mining operations have significantly altered land surface elevations. The highest elevation is in the southwestern portion of the gravel mine ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 5 property, and the lowest elevations occur in the eastern portion of the Site where open excavations remain. No permanent surface water features are present on the Site. Land cover consists of large expanses of exposed gravel and soil, some grass-covered areas, small areas of asphalt and concrete pavement, and asphalt and concrete waste. Roads adjacent to the Site include Whitefish Stage Road (western Site boundary); East Oregon Street (to the south and east); Flathead Drive (to the north and east); and an unnamed gravel road that forms the northern property boundary. A BNSF rail line parallels Flathead Drive and East Oregon Street, and a rail spur extends from east to west on the north side of the Site. 1.2 Geologic and Hydrogeologic Conditions Metamorphosed sedimentary bedrock of the Belt Supergroup underlies the Flathead Valley (including the Site). The bedrock is overlain by Tertiary- and Quaternary-age valley-fill sediments (Harrison et al. 1992; LaFave 2000). Glaciofluvial processes deposited alluvial sand and gravel above the Tertiary-age sediments. A confining unit (clay and gravelly silt) separates the deeper aquifer (alluvial sand and gravel) from an unconfined surficial aquifer within the valley. The deeper sand and gravel aquifer supplies most of the potable water to the Kalispell area (Smith 2000a). Several supply wells on the Site were completed to depths of approximately 250 feet below ground surface (bgs); however, most of the potable water near the Site is supplied by domestic and public water supply wells that are completed in the unconfined surficial aquifer. The upper 600 to 1,000 feet of valley fill materials were deposited in the Quaternary Period during the most recent glacial cycle. These sediments consist of alluvium, glacial till, and glaciolacustrine deposits. According to Smith (2000b), surficial deposits on the Site consist of Quaternary-age river terrace and glacial lake sediments. Observations at an exposed stratigraphic section in the eastern portion of the Site near Flathead Drive were consistent with alluvial terrace deposition and glacial lake sediments (AMEC 2011c). Well- to poorly-sorted and interbedded sand, gravel, and silt were observed (consistent with fluvial deposition). The finely laminated silt observed on the Site is typical of lacustrine deposition. According to the Remedial Action Work Plan for the adjacent KRY Facility (Trihydro Corporation 2009), all three hydrostratigraphic units (deep artesian aquifer, confining unit, and unconfined aquifer) underlie the Site. The unconfined aquifer at the KRY Facility consists largely of sandy, silty gravel and gravelly, silty sand with minor amounts of clay, silt, and fine- to coarse-grained sand. Investigations at the KRY Facility to date have been restricted to the shallow aquifer and the confining unit. Unconfined groundwater present at depths of approximately 20 feet bgs near the Site is likely disconnected from the deeper artesian aquifer (Smith 2000a; Trihydro Corporation 2009). In August 2006, the groundwater flow direction in the shallow aquifer was to the east-southeast on the adjacent KRY Facility and on the northern and eastern portion of the Site (Trihydro Corporation 2009). According to records maintained by the Montana Bureau of Mines and Geology (MBMG 2011), the former gravel mine operator (McElroy & Wilken, Inc.) is the listed owner for several wells located on the Site. Total depths listed for these wells ranged from 240 to 260 feet bgs, and static water levels were between 30 and 40 feet bgs. These wells were completed in the deep artesian aquifer. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 6 1.3 Current and Future Use of the Site and Adjoining Parcels Five buildings are located in the northwestern portion of the Site: an inactive concrete batch plant, a scale office/weigh station, an older wood frame building (tire shop), a steel-frame structure (repair shop), and a Quonset hut (Figure The steel structure is currently under lease to Butch Barber Trucking for use as a truck repair shop. The trucking company also uses the nearby Quonset hut as a storage facility. The three other buildings are apparently unused. Portions of the Site not associated with structures comprise gravel pits; gravel, soil, concrete, and asphalt stockpiles; internal roads; and uncovered storage areas. The majority of available aggregate products have been mined from the Site. According to Mr. Alrick Hale of KRC, the company does not plan to conduct additional mining or resume operations at the concrete plant. It is our understanding that KRC is in final negotiations with a party to sell the land. Future commercial and industrial use is anticipated. Properties north of the Site are or were used for industrial purposes. Former operations included a lumber yard and a refinery. Current business uses north of the Site include a lumber yard and a stone supply company. Land uses east of the Site include a mix of commercial/retail and industrial businesses, professional offices, and single-family residences. A rail line is located east of the Site. Single-family homes, a truck repair shop, and a trailer park are located south of the Site. The KRY CECRA Facility (see Section 2.1) encompasses property located east and northeast of the Site, as well as a portion of Tracts 1, 5, and 6 of the Site (Figure KRC owns undeveloped land west of Whitefish Stage Road that is within the floodplain of the Stillwater River (Figure Lands further west and south are owned by the City of Kalispell and are part of Lawrence Park. Lands north of the Whitefish Stage Road bridge are under commercial and residential ownership. 1.4 Site Land Use The Kalispell Growth Policy Future Land Use Map designates the Knife River property as industrial land. According to the City of Kalispell Planning Department, the Site currently falls within the I-2 (Heavy Industrial) Flathead County Zoning District, which was developed to “provide for industrial uses to accommodate heavy manufacturing, processing, fabrication, and assembly of parts or materials” (City of Kalispell 2011). The I-2 District also allows for light industrial uses, which are those that “typically do not create objectionable by-products (such as dirt, noise, glare, heat, odors, smoke, etc.), which extend beyond the lot lines”. If the City of Kalispell annexes the Site, it would most likely fall into one of the following zoning districts:  B-5 (Industrial-Business) o Accommodates a variety of business, warehouse, and light-industrial uses. o Typically found in areas designated as industrial or urban mixed use on the Growth Policy map. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 7  I-1 (Light Industrial) o Provide areas for light industrial, research and technology uses. o Typically restricted to areas designated as industrial on the Growth Policy map.  I-2 (Heavy Industrial) o Provides areas for heavy industrial uses to accommodate heavy manufacturing, processing, fabrication and assembling of products or materials. o Typically restricted to areas designated as industrial on the Growth Policy map. If the recommendations in Section 11.0 below are implemented, the Site is suitable for business and industrial uses consistent with the Zoning Districts specified above. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 8 2.0 RECOGNIZED ENVIRONMENTAL CONDITIONS (RECS) The following sections provide background information on the Recognized Environmental Conditions (RECs) identified in the Phase I ESA (AMEC 2011a). These RECs formed the basis by which AMEC developed the scope of the Phase II ESA. 2.1 KRY CECRA Facility The Kalispell Pole & Timber (KPT), Reliance Refining Company (Reliance), and Yale Oil Corporation (Yale) sites neighbor each other and represent sources of contamination that represent a potential environmental risk to the Site. The DEQ is overseeing cleanup of the sites as one property called the KRY Facility. The DEQ has designated the KRY facility as a high priority CECRA site. A portion of the Site is located within the boundaries of the KRY Facility (Figure Groundwater and soil contamination originating at the KRY facility has migrated onto the northeastern portion of the Site. The KPT site is an inactive wood treating facility that operated from approximately 1945 to 1990. The Reliance facility is an inactive oil refinery that operated from 1924 until the 1960s. The Yale facility is an inactive petroleum bulk plant and product refinery that operated from 1938 to 1978. Soil and groundwater are contaminated with pentachlorophenol (PCP), dioxins/furans, polynuclear aromatic hydrocarbons, petroleum hydrocarbons, and metals. The DEQ issued a Record of Decision (ROD) for the KRY Facility in June 2008 (DEQ 2008). The site remedy includes the following components:  Institutional controls, including land use restrictions and a controlled groundwater area;  Consolidation of dioxin/furan-contaminated soils in an onsite repository;  Excavation and disposal of lead-contaminated soils and recovered product;  PCP-and petroleum hydrocarbon-contaminated soil treatment in an onsite RCRA land treatment unit;  Free-product (light non-aqueous phase liquid or LNAPL) recovery;  Chemical oxidation of the groundwater plume (PCP, dioxins/furans, and petroleum hydrocarbons);  Monitored natural attenuation for petroleum hydrocarbons and metals in groundwater; and  Long-term groundwater monitoring. In October 2009, the DEQ issued a Remedial Action Work Plan (RAWP, DEQ 2009) for the KRY Facility that describes the implementation of the remedy. The RAWP indicated that contaminated soils are present on portions of the Site within the CECRA boundary (Figure Soils contaminated with lead, dioxins, and petroleum hydrocarbons were detected on the far northeasterneastern portion of the Site. Up to 0.5 feet of free-product has been observed in monitoring wells completed on the north central area of the Site. In addition, groundwater in the northeastern area of the Site is contaminated above DEQ groundwater ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 9 standards with metals (manganese and iron), petroleum hydrocarbons, PCP, and dioxin/furans; however, the extent of groundwater contamination has been defined by the CECRA boundary (Figure According to Ms. Moriah Bucy, DEQ Project Manager for the KRY Facility, surface and subsurface soils containing elevated concentrations of lead in the far northeastern portion of the Site were excavated in October 2010. The excavation completion report indicated that the remediation effort successfully removed soils containing lead from the Site. Based on this information, the DEQ determined that the soil excavation to remediate lead on the KRY Facility was complete. At this time, there is no contaminated soil associated with sources at the KRY facility thought to be located on the Site, with the exception of contaminated soil located within the groundwater smear zone. Contaminated groundwater is located on the Site within the CECRA facility boundary shown on Figure 2. Remediation of soil and groundwater at the KRY Facility is ongoing and cleanup activities are anticipated to continue for several years. 2.2 Hydrocarbon Impacts to Soils at the Truck Repair Shop Several waste oil containers and 55-gallons drums were observed during the Phase I site visit along the northwest side of the Truck Repair Shop (Figure Soil staining was observed around the drums. AMEC also noted soil and building foundation staining near steel and plastic piping entering the subsurface in this area. A parts washer, aboveground waste oil tank, buckets containing waste oil, and various hydrocarbon and chemical containers were also present along the northwestern interior wall of the shop, coincident with the exterior staining. AMEC contacted Mr. Butch Barber, current operator of the trucking business about the soil staining. According to Mr. Barber, a former waste oil underground storage tank (UST) located north of the shop building was removed. This information is consistent with DEQ records. Mr. Barber felt that the hydrocarbon impacts we observed were likely restricted to surface soils. He indicated that containers observed during the Phase I ESA consisted largely of waste oil and antifreeze, and that waste oil is burned as a heat source for the repair shop. He also said that pipes on the northwest side of the building were previously used to fill the waste oil tank, but that they are not currently in use. Interviews with KRC staff indicated that the waste oil UST has been removed. 2.3 Sumps at the Truck Repair Shop During the Phase I ESA site inspection, AMEC observed two sumps associated with the repair shop. An interior sump was located parallel to and in the northern half of the shop. This structure consisted of a concrete-lined trench approximately three feet deep. The walls and floor of the sump contained minor staining, but appeared to be intact and in good condition. Several drains in the floor of the shop emptied into the interior sump. An exterior sump was observed near the northwest corner of the Truck Repair Shop. Although the walls of the sump appeared to be constructed of concrete, fluid in the sump at the time of the Phase I ESA site visit prevented observation of the bottom of the structure. A mechanic present during the Phase I Site visit stated that the contents of the interior sump were routinely removed and transferred to the exterior sump. A previous Phase I ESA of the Site (Olympus Technical Services 2002) indicated that water from the exterior sump was spread on Site, and sediment was stockpiled in an on-site bermed area. However, the 2002 ESA did not provide the locations of the sediment stockpile and wastewater application area. The ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 10 stockpile may have been associated with an onsite plastic-lined pit (see Section 2.5), although this could not be confirmed. According to KRC employee interviews, trucks, excavators, other equipment, and various parts were washed near the sump outside the repair shop (Figure However, none of the employees could provide definitive information about the locations of the sediment stockpile or wastewater disposal point. 2.4 Asbestos and Lead-Based Paint in Structures The ages of the on-site structures suggested that they might contain asbestos and/or lead-based paint. Although these materials are not RECs per the ASTM standard (ASTM International 2005), asbestos and lead-based paint were considered to be environmental liabilities for the Site, particularly since there is the potential for demolition of the buildings in the future. 2.5 Other Potential RECs 2.5.1 Plastic-Lined Pit During the Phase I ESA, a plastic-lined pit or depression was identified near the northern boundary of the Site (Figure KRC employees and DEQ staff did not know the origin or purpose of this feature; however, it appears that it could have been used as a secondary containment cell. The 2011 Phase I ESA did not identify the depression as a REC because there was no indication that a release had occurred in connection with the feature. 2.5.2 Leaking Underground Storage Tank According to Ms. Marcile Sigler (DEQ Petroleum Technical Section), one petroleum release identification number (2507) has been assigned to the Site. The release was confirmed in January 1995 when several underground storage tanks (USTs) were removed. Release 2507 appears to be associated with two separate onsite releases: a diesel dispenser and a waste oil UST. Over-excavation at the diesel tank area south of the truck repair shop produced approximately ten cubic yards of soil. According to Ms. Sigler, the soil excavated at the diesel tank area was processed through an onsite washer and was mixed into a cement batch. A second source of contamination was documented in soil at the older waste oil tank (north of the truck repair shop). Release 2507 is listed as inactive by the DEQ, and DEQ closed the file in March 2005. According to the closure letter, corrective actions were proper and no additional investigation or cleanup was required. Residual hydrocarbon contamination remains in soil at the location of the former waste oil tank, but the DEQ indicated that concentrations were below The above information indicates that the release is a historical REC, but is not necessarily a current REC. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 11 3.0 PHASE II INVESTIGATION PURPOSE AND APPROACH The purpose of the Phase II ESA was to gather data necessary to evaluate data gaps associated with RECs identified in Section 2.0. The specific objectives of the Phase II ESA included the following: 1. Evaluation of the extent of surface and subsurface soil impacts next to the Truck Repair Shop sump where oil has been stored above and below ground and where there is evidence of an oil release to surface soils. 2. Assessment of potential environmental impacts associated with the Truck Repair Shop sump. 3. Investigation of surface soils where shop sump sediments had reportedly been disposed of on site. 4. Collection of groundwater samples from selected existing onsite monitoring wells to evaluate current groundwater quality conditions related to migration of contamination from the KRY CECRA Facility. 5. Inspection of the plastic-lined pit/depression and sampling of soil stockpiled inside the feature to evaluate if it represents an environmental concern. 6. Surveying of onsite structures for asbestos and lead-based paint. 7. Preparation of preliminary cleanup cost estimates for soil. 3.1 Triad Approach In accordance with EPA site assessment guidance, AMEC utilized the Triad Approach for the environmental assessment at the Site. The Triad Approach helps manage uncertainty and employs innovative characterization tools and strategies to improve site characterization. The primary goal of the Triad Approach is to increase confidence in project decisions concerning contaminant presence, location, fate, exposure, and risk (EPA 2004). The approach comprises three primary components: 1) Systematic Project Planning, 2) Dynamic Work Strategies, and 3) Real-Time Measurement Technologies. Additional details regarding the Triad Approach are provided in the SAP (AMEC 2011c). Elements of the Triad Approach that were used for the Phase II ESA are described below.  AMEC used the findings of the Phase I ESA and interviews with KRC employees to develop both a site-specific conceptual model of contamination and the scope of work.  The SAP was developed with the potential end use of the property in mind (i.e. commercial and/or industrial development), although data were compared to residential screening levels as well.  Laboratory reporting limits were compared to generic soil screening levels prior to conducting the field assessment to ensure that the data collected would allow stakeholders to make informed decisions with respect to contamination and redevelopment. This approach reduced the potential for collecting unusable data. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 12  The field team leader was responsible for communicating with the project manager and was authorized to make decisions to adapt the work plan based on observed field conditions.  The SAP allowed for the collection of additional soil and/or groundwater samples based on field observations or analytical results in an effort to determine the extent of contamination. This approach was advantageous because it: 1) allowed for decisions concerning contamination extent in the field; 2) increased the amount of data and information that could be collected during a single mobilization; 3) reduced the time and costs required for preparation of supplemental planning documents.  All laboratory analytical data were provided in an electronic format, which allowed AMEC to evaluate and manage the data more efficiently.  AMEC used a photoionization detector (PID) capable of providing real-time measurements of volatile concentrations in soil to aid in evaluating sampling frequency, identifying specific areas of contamination, and determining the need for supplemental sample locations. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 13 4.0 FIELD AND ANALYTICAL METHODS The following sections detail the methods AMEC employed to evaluate potential onsite impacts to soil and groundwater and to determine whether onsite buildings were contaminated with asbestos and lead-based paint. All fieldwork was conducted in accordance with the site-specific Health and Safety Plan (AMEC 2011c), the Final Quality Assurance Project Plan (QAPP) for the City of Kalispell Brownfield Project (AMEC 2011d), and AMEC standard operating procedures (SOPs) applicable to the scope of work (AMEC 2011c). AMEC documented soil sampling locations by measuring their distances from fixed onsite points that are visible on aerial photographs. Monitoring well locations were determined during previous surveying efforts. All field observations (including but not limited to soil types, visual indications of potential contamination, and sample locations) were recorded in a project-dedicated field book (Appendix B) or on appropriate field forms. Prior to the field investigation, AMEC contacted the Flathead County UDIG Underground Utility Location Center to have all buried public utilities marked at the Site. Utilities identified on the Site included electric power, natural gas, communication, and water lines, as well as the onsite septic system. Electric, gas, and communication lines were noted near the southwest corner of the Truck Repair Shop. The water line serving the repair shop reportedly entered the structure along its southeast side. The septic tank was located near the northwest corner of the building. 4.1 Site-Wide Groundwater Sampling As part of the cleanup process for the KRY State Superfund facility located directly north of the Site, groundwater sampling was conducted to evaluate the extent of groundwater quality impacts (Trihydro Corporation 2009). Groundwater impacts have been documented on the Site (Table The primary contaminants of concern in groundwater are PCP, dioxins, petroleum hydrocarbons, and metals (iron and manganese). The last comprehensive onsite groundwater sampling event (during which all contaminants of concern were analyzed at the same time) was completed more than five years ago. For this reason, AMEC collected groundwater samples from selected onsite monitoring wells to evaluate current trends in groundwater quality. Prior to groundwater sampling, water level measurements were collected from each well using a decontaminated electronic well probe to allow for determinations of groundwater elevations and groundwater flow directions. AMEC sampled or attempted to sample groundwater from monitoring wells KPT-16, KRY 102A and 102B, KRY 104A, KRY 107A and 107B, KRY 111A and 111B, and KRY 121A (Figure The DEQ controls access to the KRY wells, and BNSF Railway Company maintains monitoring well KPT-16. AMEC coordinated with DEQ and BNSF to sample the wells. Groundwater samples were submitted to Pace Analytical Services (Pace) of Billings, Montana for analysis of EPH, VPH, RCRA metals, iron, manganese, PCP, and dioxins (Table 2 and Table AMEC did not sample monitoring wells KRY 111A and KRY 121A during the Phase II ESA. Well KRY 111A contained petroleum free product (consistent with two sampling events conducted in 2010). AMEC was ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 14 unable to sample well KRY 121A due to an obstruction in the well casing. The cause of the obstruction is unknown. Groundwater samples were collected using low-flow sampling procedures, as outlined in ASTM Standard D 6771-02 and DEQ’s low flow purging and sampling guidance (DEQ 2005). To purge the wells and collect the samples, AMEC used a 0.85-inch diameter stainless steel bladder pump that can be fully disassembled and decontaminated in the field. New polyethylene tubing was used at each well. All non-disposable down- hole sampling equipment was decontaminated. Field parameters measured during well purging include temperature, specific conductance, pH, dissolved oxygen, oxidation-reduction potential (ORP), and turbidity. Groundwater sampling forms are contained in Appendix C. All samples were shipped in ice-filled and sealed coolers under chain-of-custody documentation. Each cooler was secured with strapping tape and displayed a shipping label with laboratory contact information. The chain-of-custody form identified each sample, specified the date and time of sample collection, and listed the requested analyses for each sample. Because all EPH screen concentrations were less than 1,000 micrograms per liter (µg/L), Pace did not analyze EPH fractions or PAHs (consistent with DEQ requirements). Groundwater QA/QC samples were collected in accordance with the SAP and the QAPP (AMEC 2011a and AMEC 2011d). Groundwater QC samples included a blind field duplicate, an equipment rinse blank, and a trip blank. The field duplicate was collected to evaluate the accuracy of the laboratory. The equipment rinse blank (ERB) sample was collected to evaluate the completeness of decontamination procedures. The trip blank was submitted to assess the potential for sample contamination during sample shipment. AMEC collected the ERB sample by pouring deionized water over decontaminated reusable sampling equipment and collecting the rinse water in sample containers. The field duplicate and equipment rinse blank were analyzed for the same constituents as the natural samples. The trip blank was analyzed for VPH. Wastes fluids generated during the site-wide groundwater sampling event included groundwater and decontamination fluids from the washing/rinsing process. PCP present in groundwater and/or free product in several of the sampled monitoring wells has been determined by the DEQ to be an FO32-listed hazardous waste, and as such, may not be applied to the land surface. Therefore, purged groundwater, rinse water, and wash water generated at these wells was containerized in a 55-gallon drum. AMEC sampled the drum contents to determine the appropriate waste disposal method. The drums were stored within secondary containment devices in a secure location on the Site pending receipt of laboratory analytical results. 4.2 Soil Investigation at the Truck Repair Shop Area AMEC completed a soil investigation in an attempt to document the depth and lateral extent of surface soil staining in proximity to the truck repair shop foundation and nearby waste oil drums. During the Phase I ESA, observation of the ground surface was hindered by the presence of pallets, logs, small aboveground storage tanks, drums, containers, hydraulic components, piping, and other miscellaneous equipment. Prior to the investigation, AMEC worked with KRC and Mr. Butch Barber to relocate these materials in order to obtain access to the area for sampling. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 15 Gray and Sons Excavating of Bigfork, Montana completed test pits in the general area of soil staining. AMEC determined the number, location, and depth of the test pits in the field based on observed contaminant impacts. Three test pits (TP-1, TP-2, and TP-3) were completed along the northwestern side of the repair shop (Figure Test pit depths varied from 3.5 feet to 9.0 feet bgs. Appendix D contains test pit logs. After soil sampling was complete, material excavated from each test pit was placed back in the pit in the reverse order that it was excavated, and topsoil material was returned to the top of the pit to the extent possible. Each test pit was photographed (Appendix AMEC described soil lithologic characteristics encountered in the test pits in a field book in accordance with the Unified Soil Classification System (USCS) as described in ASTM D2488-00 (Visual-Manual Procedure) and SOPs. Soil descriptions included, but were not limited to, major and secondary lithologies, color, qualitative moisture content, soil structure, and additional descriptive modifiers associated with contaminants). At least two soil grab samples were collected for laboratory analysis from each test pit. Sample depths were determined in the field, and samples of both impacted and non-impacted soil were submitted for analysis to determine the extents of impacts. In addition, AMEC collected a surface soil sample in a heavily- stained area to characterize the petroleum source. AMEC screened soils in the field for the presence of volatile organic compounds (VOCs) with a Photo- Ionization Detector (PID) to help determine which soil samples to submit for analysis. Prior to completion of the test pit investigation, AMEC’s field team leader discussed conditions encountered in the test pits with AMEC’s Project Manager to determine the adequacy of the investigation and the sampling effort. To prevent cross-contamination between soil samples and test pits, all sampling equipment was decontaminated between sampling locations using distilled water, alconox detergent, and a methanol rinse. Decontamination procedures were conducted at a designated location on the property that was located an appropriate distance from sampling activities. All soil samples were submitted to Pace for analysis of Extractable Petroleum Hydrocarbons (EPH), Volatile Petroleum Hydrocarbons (VPH), volatile organic compounds (VOCs) and Resource Conservation and Recovery Act (RCRA) Metals (see Table 2 and Table Samples having a reported EPH screen concentration above 200 milligrams per kilogram (mg/kg) were also analyzed for EPH fractions and polynuclear aromatic hydrocarbons (PAHs). Quality Assurance/Quality Control (QA/QC) samples, which were collected in accordance with the SAP and the QAPP, included an equipment rinse blank sample and a trip blank. The rinse blank was analyzed for EPH, VPH, VOCs, and RCRA metals, and the trip blank was analyzed for VPH. Field duplicates for soil samples were not collected due to soil heterogeneities. All soil samples were placed in ice-filled and sealed coolers for shipment to the laboratory with chain-of- custody documentation that specified the laboratory analyses for each sample. Each cooler was secured with strapping tape. The SAP proposed the installation of one monitoring well in the petroleum source area and a second monitoring well downgradient of the source area if the test pit investigation indicated that petroleum contamination may have reached the shallow aquifer in the repair shop area. Based on site observations and soil laboratory analytical results, neither of the two proposed wells was installed. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 16 4.3 Sump Inspection and Sediment Sampling During the Phase II ESA, AMEC probed the sump (Figure 3) to determine its total depth, to evaluate the competency of its bottom, and to determine if sediment was present in the sump. AMEC collected a sample of sediment for analyses of EPH, VOCs, and RCRA metals. Because the EPH screen concentration was greater than 200 mg/kg, the sample was also analyzed for EPH fractions and PAHs. Sampling and shipping procedures were similar to those for surface soils as described above. The SAP proposed the installation of one monitoring well near the sump if the sump inspection and/or analytical results indicated that soils and/or groundwater may have been impacted by release(s) from the structure. Based on the sump inspection, which showed it to have a competent concrete bottom, and the sediment laboratory analytical results, a monitoring well was not installed. 4.4 Building Material Inspections Existing buildings may be renovated or demolished if the property is redeveloped. Therefore, AMEC and its subcontractors completed an inspection and sampling of onsite buildings to evaluate the presence of asbestos-containing building materials (ACBMs) and lead-based paint (LBP) in interior and exterior finishes. 4.4.1 Asbestos Sampling TDH Engineering, Inc. (TDH) of Kalispell, Montana and its subcontractor (ALM Consulting, LLC of Helena, Montana) completed a visual survey of the onsite structures to identify potential ACBMs. Samples were collected from all suspected ACBMs in accordance with SOPs included in the SAP (AMEC 2011a) and submitted to Carolina Environmental Inc. of Cary, North Carolina for laboratory analysis of asbestos by EPA Method 600/R-93/116 (polarized light microscopy). Duplicate samples were not collected because several samples were obtained from each suspected ACBM. Repairs to the material sampling locations were made to prevent asbestos exposure. Building materials were considered ACBMs if they contain greater than 1% asbestos by weight, as defined in the National Emissions Standards for Hazardous Air Pollutants (NESHAP) under 40 CFR Part 61. 4.4.2 Lead-Based Paint Sampling To identify LBP associated with the structures, TDH and ALM sampled painted surfaces in accordance with SOPs included in the SAP (AMEC 2011a). The number and location of paint samples was determined by the number of different paints and substrates identified during the sampling effort. During the survey, areas with similar substrates and paints were identified and considered homogenous with respect to sampling. Toxicity Characteristic Leaching Procedure (TCLP) lead analysis was completed to determine if the demolition of a building would generate a waste steam considered to be a characteristic hazardous waste under RCRA. Proportional samples of the entire potential waste stream of each building were collected and analyzed for TCLP lead. Samples for analysis of TCLP lead (EPA Method 1311) were submitted to Carolina Environmental, Inc. Duplicate samples were not collected because several samples were obtained from each homogenous area of potential LBP. Confirmation of lead content in paint chips by laboratory analysis was expressed as weight of lead per weight of sample. Paint having a total lead concentration greater than 0.5% or 5,000 milligrams per kilogram (mg/kg) was identified as LBP and will require in-place management or abatement. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 17 4.5 Plastic-Lined Pit Figure 2 shows the location of a lined pit near the northern boundary of the Site. To the extent possible, AMEC evaluated the integrity of the plastic liner. Samples of soil stockpiled in the lined pit were also collected to evaluate the presence/absence of potential contaminants of concern. AMEC collected three five-point composite samples of soil within the pit (Lined Pit – 1, Lined Pit – 2, and Lined Pit – Soil samples were obtained using a hand trowel. All samples were submitted to Pace for analysis of EPH, VPH, PCP, and metals (see Table 2 and Table The soil investigation methods were identical to those described above with respect to sample recording, handling and shipment. The SAP proposed the collection of up to three soil grab samples from below the liner material in locations where the integrity of the liner had been compromised. AMEC’s inspection revealed several small breaches in the liner along the pit’s sloped sidewall; however, no breaches in the bottom of the pit were documented. Therefore, AMEC did not collect subsurface samples below the liner. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 18 5.0 DEVIATIONS FROM THE SAP The SAP specified that AMEC would collect groundwater samples from monitoring wells KRY 111 A and KRY 121 A. Because well KRY 111 A contained free product (LNAPL), groundwater samples were not collected. A casing obstruction prevented the collection of groundwater samples from well KRY 121 A. In accordance with the SAP, soil samples were to be collected at the sump sediment disposal location. No samples were collected at the sump sediment disposal area because AMEC was unable to field-verify the disposal location. AMEC attempted to work with KRC staff and Mr. Butch Barber to identify, to the extent possible, the exact location where sediments were reportedly placed on the site (AMEC 2011c). Mr. Barber indicated that the location of sediment placement was likely under asphalt and concrete waste stockpiles that were placed on the eastern portion of the property; however, he was not able to field verify the location of the sediment stockpile. Due to the lack of additional location information, AMEC did not collect surface soil samples in association with the reported sediment disposal location. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 19 6.0 SOIL SCREENING LEVELS AND GROUNDWATER STANDARDS 6.1 Soil Screening Levels The SAP indicated that AMEC would compare soil contaminant concentrations to generic (not site-specific) EPA and DEQ screening levels. Generic soil screening levels (SSLs) were designed to assess contamination at properties and evaluate specific contaminants that may pose risks for human health and/or the environment. Generic SSLs were developed using average values for physical and chemical parameters lithologies/soil types, soil porosity, aquifer properties, and fractions of organic material) that are representative of a “typical” site. The tables included with this report provide analytical results for soil samples collected on the Site as well as applicable generic SSLs to allow the reviewer to compare concentrations found in samples collected from the site to screening levels. Potential human and environmental risks and exposures vary based on land use. For example, residential land uses are typically characterized by continuous site occupancy, and risks to children must be considered. For industrial sites, tolerable risk levels are usually higher because site workers are present on the property for a limited time each day, and therefore the risks from direct contact are considered to be lower. Soils whose contaminant concentrations are below residential screening levels are assumed not to pose risks for commercial or recreational land users. Several EPA and DEQ screening levels were used in this Phase II ESA. These included:  EPA residential direct-contact regional screening levels (RSLs)  EPA industrial direct-contact RSLs  EPA leaching to groundwater soil screening levels (SSLs)  Montana Tier 1 Risk-Based Screening Levels for residential, commercial, and leaching to groundwater exposure pathways. Direct-contact RSLs were developed to protect human health and consider the potential for contaminant contact through dermal absorption or ingestion. Leaching RSLs allow for evaluation of environmental risks by assessing the likelihood of groundwater contamination via migration through the soil profile. Montana Tier 1 were established for petroleum releases as concentrations believed to be protective of both direct contact and consumption of groundwater via leaching. DEQ developed for both surface and subsurface soils. Subsurface soil vary based on the depth to groundwater. If onsite contaminant concentrations are below generic RSLs and Montana Tier 1 the property is considered to pose an acceptable risk to human health and the environment, and no additional investigation or remedial actions is warranted. If the concentrations of contaminants in soil at a property are found to exceed generic RSLs or site-specific cleanup levels are often calculated to determine if concentrations exceed acceptable human health thresholds for current and anticipated future property uses. Site-specific cleanup levels are calculated using assumed or measured values of physical and chemical parameters representative of the site in question. If concentrations are found to exceed site-specific cleanup levels, soil and/or groundwater remediation is commonly required to obtain regulatory closure. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 20 According to DEQ, existing site-specific cleanup levels calculated for the KRY Facility apply to samples collected within the facility’s exterior boundary, which includes a portion of the Site (Figure Based on the analytical results presented in this SAP, calculation of site-specific cleanup levels was not required. 6.2 Groundwater Standards As specified in the SAP, contaminant concentrations in groundwater samples collected at the Site were compared with Montana Numeric Water Quality Standards (DEQ 2010b) and Montana Tier 1 groundwater for petroleum constituents. Groundwater standards were developed by DEQ for the protection of human health. The tables included with this report provide analytical results for groundwater samples collected on the Site and a comparison of concentrations to these standards and ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 21 7.0 RESULTS The sections below present the field and analytical results of the Phase II ESA. Laboratory analytical reports for soil and groundwater samples are contained in Appendix G. 7.1 Groundwater Occurrence and Groundwater Flow AMEC measured depths to water prior to collecting groundwater samples at each of the monitoring wells (Figure Table 4 is a summary of selected monitoring well construction details, measuring point elevations, depths to water, and groundwater elevations collected between September 14 and September 16, 2011. Depths to groundwater ranged from 19.1 to 27.0 feet below the top of the PVC casings. Because the monitoring wells are approximately located along an east-west orientation, groundwater elevation data were not sufficient to construct potentiometric maps of the shallow and deep aquifers. The data indicate that groundwater elevations are generally higher at the western end of the Site. Data collected by DEQ during previous investigations of the KRY facility (TetraTech EM, Inc. 2008), showed that onsite groundwater flow directions were to the east-southeast in both the upper and the lower portions of the unconfined aquifer. 7.2 Groundwater Analytical Results AMEC collected groundwater samples from seven onsite monitoring wells. Below is a summary of analytical results, which are presented in Tables 5 through 7.  All metals concentrations were below applicable Montana Numeric Groundwater Quality (DEQ-7) Standards.  Concentrations of all volatile petroleum hydrocarbons (VPH) and extractable petroleum hydrocarbons (EPH) were below analytical reporting limits and  In wells KRY 102A and KRY 102B, concentrations of contaminants of potential concern were below detection limits in 2011 and in previous (historic) samples collected from these wells.  Toluene was detected in well KRY 104A in 2006 but not in 2011. This result is consistent with an improvement in groundwater quality in this well since the last sampling event.  Although PCP was detected in samples collected from several wells, concentrations were below the DEQ-7 Numeric Water Quality Standard.  Dioxins were detected at concentrations ranging from 1.1 to 3.4 pg/L in 2011. Although this value is above the DEQ-7 standard of 2.0 pg/L, it is below the KRY Facility cleanup level of 5.6 pg/L. The concentrations of dioxins detected in groundwater are likely indicative of background dioxin concentrations within the aquifer. Dioxin concentrations were either similar to or lower than the most recent historic samples collected from the wells.  AMEC did not sample well KRY 111 A due to the presence of free product on the water table. Groundwater at this well is likely contaminated with PCP, dioxins/furans, manganese, iron, and petroleum hydrocarbons at concentrations above DEQ water quality standards.. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 22  Well KRY 121A was not sampled due to an obstruction in the PVC casing. During previous sampling events, groundwater at this well contained PCP, dioxins/furans, manganese, iron, and petroleum hydrocarbons. 7.2.1 Investigation-Derived Waste A sample of wastewater generated during the groundwater sampling process (Table 7) contained PCP at a concentration of 0.19 g/L. This concentration is below the DEQ-7 water quality standard and the KRY Facility cleanup level (both 1.0 Therefore, the containerized water is not subject to special handling or disposal requirements, and may be disposed of on the ground. 7.3 Truck Repair Shop Soil Investigation AMEC collected soil samples from test pits TP-1, TP-2, and TP-3 (Figure Test pit soil analytical results (Tables 8 through 12) are summarized as follows:  Concentrations of most metals were below generic RSLs. Chromium concentrations were below the Cr-III RSL but above the Cr-VI RSL. Concentrations in the soil samples were reported as total chromium (Cr-VI + Cr-III). Historic uses of the site are not suggestive of Cr- VI generation.  Several VPH and PAH constituents were detected above laboratory reporting limits. However, all concentrations were below Montana Tier 1  Concentrations of most VOCs were below reporting limits or RSLs. The waste-oil source sample collected at test pit TP-1 contained methylene chloride at a concentration that exceeded the leaching to groundwater RSL.  In the waste-oil source sample, C9-C18 aliphatic hydrocarbon concentration exceeded the residential surface soil RBSL, but was below the commercial RBSL. Methylene chloride and C9- C18 aliphatic hydrocarbon concentrations in test-pit soil samples collected beneath the waste oil source sample did not exceed any screening levels.  At test pit TP-2, concentrations of C9-C18 aliphatic hydrocarbons exceeded the residential screening level at ground surface, but was below the commercial RBSL. C11-C22 aromatic hydrocarbon concentrations exceeded the residential and commercial in the sample collected at ground surface. Concentrations of C9-C18 aliphatic hydrocarbons and C11-C22 aromatic hydrocarbons were below screening levels at a depth of 2.5 feet bgs.  The Phase I ESA indicated that piping was observed entering the subsurface in the general location of surface staining and the former underground waste oil storage tank. The soil excavation at test pit TP-1 showed that the two pipes that appeared to enter the subsurface were in reality one pipe that formed a loop below ground surface (Appendix Although the piping likely served a former buried waste oil tank, the end of the pipe appeared to have been cut off after the tank was removed. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 23 7.4 Sump Inspection and Sediment Sampling AMEC completed an inspection of the concrete sump outside of the Truck Repair Shop (Figure 3; Appendix The walls and bottom of the square structure were constructed of concrete and appeared to be intact and fully competent. The bottom of the sump dipped toward the northeast. The area of the sump is approximately 120 square feet. Based on a mean solids thickness of 0.5 feet, the volume of sediment contained in the sump at the time of the Phase II ESA was approximately 60 cubic feet (2.2 cubic yards). Based on a mean height of the water column overlying the solids (2.2 feet), the volume of water present in the sump during the investigation was approximately 264 cubic feet (2,000 gallons). Sump sediment analytical results (Tables 10 through 12) are summarized below.  Most metals concentrations were below RSLs. Chromium concentrations were below the Cr-III RSL but above the Cr-VI screening level. The concentration in the sediment sample was reported as total chromium (Cr-VI + Cr-III). Historic uses of the site are not suggestive of Cr- VI generation.  Several PAH constituents were detected above laboratory reporting limits. However, all concentrations were below Montana Tier 1  Concentrations of most VOCs were below reporting limits or RSLs. The 1,2,4 and methylene chloride concentrations exceeded leaching to groundwater RSLs.  C9-C18 aliphatic hydrocarbon and C11-C22 aromatic hydrocarbon concentrations exceeded residential surface soil but were below commercial surface soil 7.5 Building Material Inspections 7.5.1 Asbestos TDH and ALM inspected and sampled the scale office, the mixing plant, the main shop, the tire shop, and the welding shop (Quonset hut) (Figure 3) to evaluate the presence of asbestos containing building materials (ACBM). Building materials with greater than 1% asbestos are considered ACBMs. Three building materials were determined to be ACBMs:  Mastic in the Scale Office contained 10% asbestos;  Roofing/Silver Paint in the Main Shop contained 4-10% asbestos; and  Window glazing in the Tire Shop contained 2% asbestos. Additional asbestos inspection details are provided in Appendix H. 7.5.2 Lead-Based Paint The on-site buildings have different dates of construction and were sampled separately for lead-based paint. Sampling was completed to evaluate the lead content of anticipated waste streams if one or more buildings were demolished. Waste stream lead concentrations were below the regulatory standard of 5.0 mg/L lead for four of the five buildings. The waste stream concentration at the tire shop was 5.6 ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 24 mg/L, which was largely due to lead in the structure’s exterior painted siding. Additional lead paint inspection details are provided in Appendix H. 7.6 Plastic-Lined Pit AMEC collected three five-point composite samples of surface soil located within this feature (Figure Analytical results are summarized below and in Tables 13 through 15.  Most metals concentrations were below EPA regional soil screening levels. Chromium concentrations in all samples exceeded the Cr-VI screening level but were well below the Cr-III screening level. Concentrations in the soil samples were reported as total chromium (Cr-VI + Cr-III). Historic uses of the site are not suggestive of Cr-VI generation.  VPH, PCP, and PAH concentrations were below RSLs and KRY Facility site-specific cleanup levels.  The EPH screen concentration was above the ceiling limit of 200 mg/kg, which required the analysis of EPH fractions. However, all fraction concentrations were below screening levels. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 25 8.0 DATA VALIDATION AMEC collected Quality Assurance/Quality Control (QA/QC) data to assist with decision-making regarding potential additional assessment and preferred cleanup options. We collected soil and groundwater QA/QC samples during the Phase II ESA to evaluate analytical results and to assess whether errors were introduced during sample collection, handling, and transport, or at the laboratory. QA/QC samples were collected in accordance with applicable SOPs, the SAP (AMEC 2011c), and the QAPP (AMEC 2010d). AMEC collected 11 natural surface/subsurface soil samples during the course of the Phase II ESA. The SAP did not require the collection of duplicate soil samples due to the inherent heterogeneity of soil. AMEC collected one equipment rinse blank (ERB) sample in association with the natural soil samples. We also collected a trip blank. The soil-related ERB sample was analyzed for EPH, VPH, VOCs, and RCRA metals. Lead was detected at a concentration of 2.4 mg/kg, although the concentration was estimated (above the adjusted method detection limit and below the adjusted reporting limit). Lead concentrations in both the ERB and in the natural samples were well below EPA generic RSLs. Although benzene was detected at a concentration of 0.27 mg/L in the ERB sample, its concentration was also estimated. All natural-sample benzene concentrations were below reporting limits. Concentrations of all other constituents analyzed in the soil-related ERB sample were below laboratory reporting limits. Concentrations of all constituents in the trip blank were also below reporting limits. AMEC collected seven natural groundwater samples during the investigation. QA/QC samples included one ERB, one trip blank, and one field duplicate. With the exception of dioxins, concentrations of all constituents were below laboratory reporting limits in the ERB sample. The dioxin concentration was 2.1 picograms per liter (pg/L). Although this concentration is above the Montana numerical groundwater standard of 2.0 pg/L, it is not likely representative of a source of contamination and is likely representative of the background concentration of the distilled water used to create the ERB sample. The dioxin concentration in the laboratory blank sample was 4.2 pg/L. Toluene was detected in the trip blank at a concentration of 0.13 g/L. The toluene concentration was estimated by the lab. Toluene concentrations in the natural samples were below reporting limits. A validation process was employed to reduce decision errors regarding the presence, locations, and concentrations of contaminants. The data validation reports (Appendix F) indicate that, with some exceptions, sample handling metrics and quality control results were within applicable thresholds. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 26 9.0 REVISED CONCEPTUAL SITE MODEL (CSM) A CSM of contamination was initially developed based on the findings of the Phase I ESA (AMEC 2011a), information contained in DEQ files, and interviews with KRC employees. AMEC revised the CSM based on data and information collected during the 2011 Phase II ESA. Based on the literature, reports of previous drilling, and the Phase II ESA, on-site soils are predominantly composed of unconsolidated and partially consolidated gravel, sand, and silt. A shallow unconfined aquifer underlies the Site at a depth of approximately 20 feet bgs. A confining unit below the shallow aquifer appears to restrict the downward migration of contaminants in groundwater. The direction of shallow groundwater flow is estimated to be to the east-southeast at the Site (Trihydro Corporation 2009). Based on this information, releases to shallow soils have the potential to migrate to the underlying shallow aquifer. Table 16 identifies sources of contamination on or adjacent to the Site, impacted media (soil, groundwater, and building materials), contaminants of concern, potential exposure pathways, and recommendations for remediation. Contaminants in groundwater have migrated onto the Site from the adjacent KRY State CECRA Facility. PCP has been detected in monitoring wells on the Site that were installed during investigations at the KRY facility. Although petroleum hydrocarbons, iron, manganese, and dioxins were not detected above screening levels in groundwater samples collected during this investigation, historic groundwater data (Table 1) indicate that these constituents are likely present in groundwater at monitoring well KRY 111 A (Figure In addition, these constituents may remain in groundwater at well KRY 121 A. With the exception of the far northeastern portion of the Site, on-site soils are not contaminated from sources originating at the KRY facility. According to Ms. Moriah Bucy of the DEQ, soils at the far northeastern portion of the Site have been or are currently being remediated under the direction of the DEQ. Waste oil stored at and below the ground surface has contaminated soils adjacent to the northwest side of the truck repair shop (Figure Poor handling and storage practices have resulted in heavy oil staining of surface soil. Information collected during this ESA is consistent with the waste oil tank having been removed from the Site. Although piping associated with the waste oil tank is still present at the Site, it has been disconnected and is no longer in use. VOCs and petroleum hydrocarbon compounds were detected above screening levels in near-surface soils associated with areas of surface soil staining. Decreases in contaminant concentrations at depth to below screening levels, however, indicate that groundwater impacts in this area are unlikely. The SAP indicated that sediment contained within the repair shop exterior sump was a suspected source of contamination to onsite soil and groundwater. The sump routinely receives wastewater from vehicle, equipment, and parts washing. Based solely on this information, there was a concern that contaminants in the wastewater and solids placed in the sump may have leaked out of the structure and migrated to underlying soil and groundwater. Although VOCs and petroleum hydrocarbons were detected in the sump sediment at concentrations above screening levels, the walls and bottom of the structure are constructed of concrete and appeared to be intact and fully competent. There was no indication of significant leakage from the sump, although leakage is possible through concrete seams. Based on all data collected to date ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 27 concerning the sump, a groundwater investigation does not appear to be warranted in association with the sump. Soils located above the liner within the plastic-lined pit did not contain concentrations of potential contaminants of concern above screening levels. Three different asbestos-containing building materials and one finish containing lead-based paint are associated with on-site structures. Abatement (removal) of these materials will be required before renovation or demolition of the associated structures. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 28 10.0 RECOMMENDATIONS Based on information and data collected during the Phase II ESA, AMEC has developed recommendations for soil remediation, additional soil investigation, and onsite groundwater use. Table 16 and the sections below provide our recommendations for each recognized environmental condition (REC) or contaminant source. Below we also provide a preliminary evaluation of cleanup costs. 10.1 Soil Remediation within the KRY Facility Boundary Soil remediation in the northeastern area of the Site is proceeding under the direction of the DEQ and is pursuant to the Record of Decision for the facility (DEQ 2008). This remedial effort should lower concentrations to acceptable levels and allow for commercial reuse of the property in this area. 10.2 Groundwater Impacts In general, concentrations of contaminants in groundwater samples collected on the eastern portion of the Site (adjacent to the KRY CECRA facility) in 2011 were similar to or lower than historic concentrations. Groundwater in this area likely remains impacted with petroleum hydrocarbons, dioxins, manganese, iron, and PCP; however we do not recommend any additional groundwater investigation or sampling. Consistent with the ROD for the KRY facility, the DEQ should create a controlled groundwater area to prevent exposure to contaminated groundwater associated with that portion of the Site that lies within the CECRA facility boundary. 10.3 Soil Remediation and Sump Sediment Removal Shallow excavation and offsite disposal of soils should be completed at the locations of test pits TP-1, TP-2, and TP-3 near the Truck Repair Shop to eliminate direct contact and ingestion of contaminated soil. AMEC also recommends removal of the sump contents and appropriate disposal off site. In addition, removal of the sump should be considered because it represents a potential source of contamination to underlying soil and groundwater. 10.4 Building Materials AMEC recommends the removal of ACBMs at the time the building(s) are demolished and/or renovated. Abatement of the asbestos will require special considerations for handling and containerization prior to demolition. The Flathead County Landfill will accept such materials provided they are appropriately containerized and transported. Special considerations for lead abatement will be required prior to demolition of the Tire Shop. The principal work required consists of removal of the exterior painted siding from the tire shop or removal of the paint from the siding prior to demolition of the building. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 29 11.0 ESTIMATED CLEANUP AND ABATEMENT COSTS This Phase II ESA defined areas of impacted soil, asbestos containing materials, and lead-based paint that should be remediated. The need for asbestos and lead-based paint abatement is predicated on the need for demolition or renovation of the onsite buildings. While groundwater is contaminated above DEQ water quality standards in the northeastern portion of the Site in the area defined by DEQ (KRY CECRA site), remedial actions to address groundwater contamination are not addressed herein. Nor are remedial actions necessary to remove petroleum and lead-contaminated soil in the far northeastern portion of the Site. Remediation of groundwater and soil within the boundary of the CECRA facility are currently the responsibility of parties named in the Record of Decision by the DEQ, and for this reason were not quantified. Acquisition of the KRC property could result in liabilities to contamination associated with the KRY facility. For this reason, we recommend that any party acquiring the Site obtained an indemnification to liability for contamination associated with the KRY CECRA facility from the DEQ. Such indemnification was provided in the past by the DEQ to McElroy & Wilken. Demolition costs of onsite structures was also not estimated. 11.1 Test Pit Soils This ESA defined areas of impacted soil that should be excavated and disposed of offsite to eliminate environmental risks. This includes soil on the north side of the Truck Repair Shop near test pits TP1, TP-2, and TP-3. The estimate below assumes that all areas around TP-1, TP-2,and TP-3 will be excavated at the same time. 11.2 Sump Sediment and Sump An environmental contractor such as Oily Waste Processors of Great Falls, Montana can be retained to remove the water-sediment mixture (slurry) from the sump. At a cost of $2.00 per gallon, the total estimated cost for removal of the sump wastes is $5,000. The estimate presented above assumes that the analytical results presented in this report for the sump sediment are sufficient to obtain approval for disposal of the slurry. An estimate to remove the sump is not included, but removal of the sump should be considered to eliminate this potential source of contamination. Costs to eliminate the sump will vary depending on whether or not it is completed as part of the building demolition. 11.3 Asbestos and Lead in Structures Appendix H provides preliminary cost estimates for asbestos and lead abatement work. The estimate for asbestos abatement is $5,000 and the lead-based paint estimate is $7,500. ---PAGE BREAK--- AMEC Geomatrix, Inc. Phase II ESA Report – Knife River Property City of Kalispell November 2011 30 Estimate Cleanup and Abatement Costs Test Pit Soil Excavation Sump Sediment Removal Asbestos and Lead Abatement Estimated Cost $10,500 $5,000 $12,500 Total Estimated Cost $28,000 Notes: a – assumes 700 cubic feet (26 cubic yards) will require excavation; soil bulk density = 1.3 g/cm3 (2191 pounds/cubic yard) or 2.2 tons/cubic yard; estimated mass to be delivered to Flathead County Landfill = approx. 58 tons. For costing purposes, the mass was doubled in case additional material needs to be removed (116 tons); Flathead County Landfill rate is $31.05 per ton; engineering oversight and testing estimated cost is $25.00 per ton; reporting is estimated at $4,000. b – assumes a slurry volume of 2,500 gallons and a disposal cost of $2.00 per gallon. ---PAGE BREAK--- AMEC Geomatrix, Inc.

LABORATORIES Pace Analytical Services - Minneapolis PASI-M Pace Analytical Services - Montana PASI-MT BATCH QUALIFIERS Batch: MSV/17661 A matrix spike/matrix spike duplicate was not performed for this batch due to insufficient sample volume. [M5] ANALYTE QUALIFIERS Fractionation performed on a 5x dilution of the sample extract. 1M Result confirmed by re-analysis 2M Sample extract diluted by 2 prior to fractionation. 3M The internal standard, Pentafluorobenzene and 1,4 Diflurobenzene, result exceed the lower control limit. The reported result should be considered an estimated value. 4M Analyte was detected in the associated method blank. B The continuing calibration for this compound is outside of Pace Analytical acceptance limits. The results may be biased high. CH Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference. D3 The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits. D6 Analyte concentration exceeded the calibration range. The reported result is estimated. E The reported result is estimated because one or more of the constituent results are qualified as such. ES Extraction or preparation was conducted outside of the recognized method holding time. H2 Analyte recovery in the laboratory control sample (LCS) was outside QC limits. L0 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results may be biased high. L1 Analyte recovery in the laboratory control sample (LCS) exceeded QC limits.

P3 Matrix spike recovery was outside laboratory control limits due to a parent sample concentration notably higher than the spike level. P6 Surrogate recovery outside laboratory control limits. S0 Surrogate recovery outside laboratory control limits due to matrix interferences (confirmed by similar results from sample re-analysis). S2 Surrogate recovery not evaluated against control limits due to sample dilution. S4 Surrogate recovery outside control limits due to matrix interferences (not confirmed by re-analysis). S5 Methylene chloride is a common laboratory contaminant.

This report presents the results from the analyses performed on five samples submitted by a representative of AMEC. The samples were analyzed for the presence or absence of and using a modified version of USEPA Method 8290. The reporting limits were based on signal-to-noise measurements. The recoveries of the isotopically-labeled PCDD/PCDF internal standards in the sample extracts ranged from 45-101%. All of the labeled standard recoveries obtained for this project were within the 40-135% target range specified in Method 8290. Also, since the quantification of the native 2,3,7,8-substituted congeners was based on isotope dilution, the data were automatically corrected for variation in recovery and accurate values were obtained. In some cases, interfering substances impacted the determinations of PCDD or PCDF congeners. The affected values were flagged where incorrect isotope ratios were obtained. A laboratory method blank was prepared and analyzed with the sample batch as part of our routine quality control procedures. The results show the blank to contain a trace level of OCDF. This level was below the calibration range of the method. Sample levels similar to the corresponding blank level were flagged on the results tables and may be, at least partially, attributed to the background. It should be noted that levels less than ten times the background are not generally considered to be statistically different from the background. Laboratory spike samples were also prepared using clean water that had been fortified with native standard materials. Recoveries of the native compounds ranged from 101-127%, with relative percent differences of 0.9-16.2%. These results indicate high degrees of accuracy and precision for these determinations. Matrix spikes were not prepared with the sample batch.

This report presents the results from the analyses performed on four samples submitted by a representative of AMEC. The samples were analyzed for the presence or absence of and using a modified version of USEPA Method 8290. The reporting limits were based on signal-to-noise measurements. The recoveries of the isotopically-labeled PCDD/PCDF internal standards in the sample extracts ranged from 60-128%. All of the labeled standard recoveries obtained for this project were within the 40-135% target range specified in Method 8290. Also, since the quantification of the native 2,3,7,8-substituted congeners was based on isotope dilution, the data were automatically corrected for variation in recovery and accurate values were obtained. In some cases, interfering substances impacted the determinations of PCDD or PCDF congeners. The affected values were flagged where incorrect isotope ratios were obtained or where diphenyl ethers were present. A laboratory method blank was prepared and analyzed with the sample batch as part of our routine quality control procedures. The results show the blank to contain a trace level of OCDF. This level was below the calibration range of the method. Sample levels similar to the corresponding blank level were flagged on the results tables and may be, at least partially, attributed to the background. It should be noted that levels less than ten times the background are not generally considered to be statistically different from the background. Laboratory spike samples were also prepared using clean water that had been fortified with native standard materials. Recoveries of the native compounds ranged from 101-127%, with relative percent differences of 0.9-16.2%. These results indicate high degrees of accuracy and precision for these determinations. Matrix spikes were not prepared with the sample batch.
