October 25, 2012 Mr. Alex Diekmann The Trust for Public Land 111 South Grand Avenue, Suite 203 Bozeman, MT 59715 Re: Phase II Investigation Report L Street Property Bozeman, Montana Dear Mr. Diekmann, Thank you for this opportunity to provide the Trust for Public Land (TPL) with environmental consulting services. This report presents the results of the Phase II investigation at the L Street Parcel (the Site) in Bozeman, Montana (Figure 1 in Attachment A). The investigation was conducted in general accordance with our proposal “Scope of Work and Cost Estimate for Phase II Investigation” dated September 21, 2012 (Tetra Tech 2012a). The scope of work for this Phase II ESA was developed based on the findings and recommendations of the Phase I ESA (Tetra Tech 2012b). The following sections present background information, methods, results, conclusions and recommendations. Attachment A presents figures, Attachment B includes tables, Attachment C provides groundwater monitoring logs, and Attachment D includes the analytical laboratory report. 1.0 SITE LOCATION AND BACKGROUND Tetra Tech conducted a Phase I ESA (Tetra Tech 2012b) for the Site in July 2012. The following location and background information presents a summary of the information obtained during the Phase I ESA. The L Street property is located in the NE¼, NE¼, Section 6, Township 2 South, Range 6 East, and the NW¼, NW¼ of Section 5, Township 2 South, Range 6 East in Gallatin County. The Site is 7.397 acres in size, has a triangular-shaped boundary, and is bisected by Rocky Creek. Certificate of Survey (COS) No. 2503 lists the Site as Tract 1 and Parcel A in the northeast portion of Bozeman. The Site was commonly known as the Vollmer Slaughterhouse and is located within the Northern Pacific/Story Mill Historic District. The property contains a complex of buildings constructed between 1938 and 1950, and originally included a slaughterhouse, a rendering plant, a small stockyard with wooden fence, loading gates, and railroad spurs along its west and northeast borders. The original buildings remain along with a new storage building, but the stockyard no longer exists. The Site was also serviced by a railroad spur that is no longer in operation. Industrial wastewater for the Site was discharged to a lagoon/wastewater infiltration pit which reportedly had concentrations of solvent present when a soil sample was analyzed by a laboratory. The Site is served by municipal water, a well, septic system, overhead electric, and underground natural gas. At least one underground storage tank (UST) was used on the property but use was TetraTech 303 Irene Street, Helena, MT 59601 Tel 406.443.5210 Fax 406.449.3729 www. tetratech.com Phase II Soil Investigation Report L Street Property, Bozeman, Montana October 25, 2012 TETRA TECH 2 discontinued in the 1970s. The UST(s) were formally removed in 2005 without permits from the Montana Department of Environmental Quality (MDEQ). The UST(s) reportedly leaked; however, no documentation exists that contamination was removed. The Idaho Pole Company (IPC) National Priority List (NPL) facility is located south of the property. A groundwater control area extends onto the Site which requires institutional controls be followed. No other regulated facilities affect the Site. Based on the results of the Phase I ESA, Tetra Tech recommended Phase II activities be performed at the L Street Property. 2.0 INVESTIGATION METHODS 2.1 Project Health and Safety Tetra Tech prepared a Health and Safety Plan (HASP) for this project to comply with Occupation Safety and Health Administration (OSHA) Code of Federal Regulations (CFR) 29 1910.120. Field personnel reviewed the HASP and conducted an on-site safety meeting prior to the initiation of field activities. The HASP and safety meeting discussed potential chemical and physical hazards that may be encountered at the Site, identified job hazards associated with field activities, described safe work practices, identified personal protective equipment and decontamination procedures, and identified project contacts, emergency medical procedures, and the location of medical facilities. 2.2 Utility Locates Tetra Tech contacted the one-call utility notification center to request a utility locate for all areas where subsurface investigations were planned prior to commencement of excavation work. Utilities were cleared the day of the investigation and all sample locations were determined to be clear of utilities. 2.3 Soil Test Pits 2.3.1 Test Pit Excavation Tetra Tech contracted with Rocky Mountain Dirt Detail, LLC (RMDD) to excavate six test pits. The test pit investigation focused on three areas of potential sources of contamination, including the former railroad spur line, UST area, and wastewater infiltration pit. The excavated test pits are as follows. Figure 2 in Attachment A shows the test pit locations. Railroad Spur Line: Three test pits (RR1 through RR3) were excavated along the railroad grade to investigate potential impacts with past use. UST Area: One test pit (UST1) was excavated to investigate potential impacts associated with the former UST area. Wastewater Infiltration Pit: Two test pits (INF1 and INF2) were excavated to investigate potential impacts associated with the wastewater infiltration pit. RMDD used a rubber track-mounted backhoe with a 24-inch wide bucket. Prior to excavation of the test pits, RMDD carefully removed topsoil and its vegetation as one piece and set it aside. After soil logging and sampling was complete, RMDD backfilled and compacted the soil removed from the test pit then placed the topsoil and vegetation piece atop the excavation. Phase II Soil Investigation Report L Street Property, Bozeman, Montana October 25, 2012 TETRA TECH 3 2.3.2 Soil Logging and Sampling During excavation, field personnel logged the soil materials encountered in each test pit to evaluate whether the soil exhibited visual indications of potential contaminants. Field personnel also performed on-site screening of excavated soil using a photoionization detector (PID) and headed headspace technique to evaluate whether there were detectable levels of volatile organic vapors. Two soil samples from each test pit were submitted for laboratory analysis. Field personnel collected a surface soil sample from the 0- to 2-foot depth interval and a subsurface soil sample from each test pit. Soil samples were placed in laboratory provided sample jars and immediately placed in a cooler containing doubled re-sealable bags filled with ice. The samples were handled under standard chain-of- custody procedures and shipped via overnight courier to Pace Analytical in Billings, Montana for analysis.Table 1, below, presents a list of analyses performed for each area.

RCRA – Resource Conservation and Recovery Act 8 RCRA Metals – arsenic, barium, cadmium, chromium, lead, mercury, selenium and silver The list of analytical parameters are based upon MDEQ Risk-Based Corrective Action Guidance for Petroleum Releases (MDEQ 2009) and Tetra Tech’s knowledge of other chemicals (i.e. solvents) that may be present at the Site. Surface and subsurface soil results were compared MDEQ’s soil screening levels (MDEQ 2009), and EPA Regional Screening Levels (RSLs) as per MDEQ’s Attachment C – Soil Screening Process Part 1 – Direct Exposure and Part 2 – Leaching to Groundwater (MDEQ 2012). 2.4 Groundwater Sampling Two (LP-3 and LP-5) of the three on-site piezometers were purged, sampled, and monitored for field parameters (Figure 2). Well LP-3 is located in the UST area and well LP-5 is located just east of the wastewater infiltration pit. These piezometers are constructed of one-inch diameter, Schedule 40 PVC pipe fitted with a slip cap and a 4-inch PVC casing and cap that acts as a well protector. The Phase II Soil Investigation Report L Street Property, Bozeman, Montana October 25, 2012 TETRA TECH 4 piezometers were purged with a peristaltic pump until greater than three casing volumes of water were removed from the well bore. Samples were collected immediately after purging. Metals samples were filtered in the field with a 0.45-micron in-line filter. Field personnel collected the groundwater samples in laboratory provided sample containers and immediately placed in a cooler containing doubled re-sealable bags filled with ice after collection. Samples were handled under standard chain-of-custody procedures and shipped via overnight courier to Pace Analytical in Billings, Montana for analysis.Table 2 lists the analyses that were performed on the samples.

Groundwater results were compared to MDEQ’s human health standards (MDEQ 2010). 3.0 INVESTIGATION RESULTS The following sections present the soil and groundwater investigation results. 3.1 Soil Results Tetra Tech completed the soil investigation on September 26, 2012.Table 3 (Attachment B) presents a test pit log for the test pits excavated for the project. The following sections discuss the locations of the test pits and soil encountered. Railroad Spur – Three test pits were excavated along the former railroad grade as shown on Figure 2. These were excavated to a depth of four feet below ground surface (bgs). No staining or unusual odors were detected during the excavation work. Headspace measurements of soil samples did not indicate impacts due to volatile organic constituents. Soil consisted primarily of dark brown, fine loamy textured topsoil above more sandy lighter colored subsoil. In places, the subsoil contained lenses of gravels which may be indicative of former historic stream flood events. The area where excavations were conducted was densely vegetated with grasses except in the immediate vicinity of the southern-most excavation (RR 3). This area was devoid of organic rich topsoil suggesting that topsoil had likely been removed, leaving the sandy subsoil which is less favorable for plant growth and establishment. Soil Phase II Soil Investigation Report L Street Property, Bozeman, Montana October 25, 2012 TETRA TECH 5 conditions were slightly moist at each of the excavations. No groundwater was encountered during excavation. Railroad spur soil samples were collected from the 0- to 2-foot and 2- to 4-foot depth intervals and submitted for laboratory analysis. Analytical results (Table 4 in Attachment B) indicate metals and PAHs were detected at or above the laboratory practical quantitation limits. However, concentrations did not meet or exceed any residential, commercial, subsurface soil, or leaching to groundwater soil screening levels. UST Area – One test pit was excavated in the approximate center of the UST area to a depth of 8 feet bgs. No staining or unusual odors were detected during the excavation work. Headspace measurements of soil samples did not indicate impacts due to volatile organic constituents. Soil consisted of a 2-foot thick interval of dark brown fine loamy topsoil covered with thick vegetation. Below this interval was an approximately 1-foot thick layer of debris (bricks, glass, copper pipes, and other garbage). Underlying the backfilled debris was dark brown fine loamy- textured native subsoil bris to a depth of about 7 feet. Below this depth were coarse gravels and cobbles. Soil conditions were slightly moist. Groundwater was encountered at 8 feet bgs. UST area soil samples were collected from the 0- to 2-foot and 7- to 8-foot depth intervals and submitted for laboratory analysis. Analytical results (Table 5 in Attachment B) indicate several EPH and VPH constituents were detected in the samples; however, concentrations were well below their respective residential, commercial and leaching to groundwater soil screening levels. Wastewater Infiltration Pit Area – The pit bottom is approximately 6 feet below the grade of the surrounding ground surface. Two test pits were excavated near the north and south margins of the infiltration pit to a depth of 4 feet below the bottom of the pit. Pit soil sample INF1 was located at the north margin and INF2 was located at the south margin of the pit. No staining or unusual odors were detected during the excavations. Cattails were growing in the pit bottom at the time of the investigation. In excavating INF1, dark gray-black organic clay was encountered from the pit surface to 4 feet bgs. Bricks and bone fragments were scattered throughout the upper portion of the INF1 excavation. In excavation INF2, tan colored clayey soil was encountered to 2 feet bgs while the remaining depth of the excavation consisted of soil that was similar to that of INF1. Groundwater was encountered at 2 feet below the pit bottom in both excavations. Infiltration pit soil samples from both excavations were collected from the 0- to 2-foot and 2- to 4-foot depth intervals and submitted for laboratory analysis. Analytical results (Table 6 in Attachment B) indicated metals and EPH were detected in all samples and VOCs in the 0- to 2- foot depth interval sample in excavation INF1. Arsenic in both samples collected from INF2 exceeded the leaching to groundwater soil screening level (see Section 4.0). In addition, both samples collected from INF1 exhibited EPH Screen concentrations above the 200 milligram per kilogram (mg/kg) screening level. As a result, EPH fractionation was performed on the sample with the highest EPH Screen concentration (INF1 2-4’). Results indicated that the concentrations exhibited by the EPH fractions did not exceed any soil screening levels. Phase II Soil Investigation Report L Street Property, Bozeman, Montana October 25, 2012 TETRA TECH 6 3.2 Groundwater Monitoring Depth to groundwater in piezometers LP-3 and LP-5 was 7.6 and 5.8 feet bgs, respectively. No sheen or unusual odors were detected during the purging of the piezometers, prior to sampling. Groundwater pH ranged between 7.5 and 7.6 standard units (s.u.) and specific conductivity ranged between 732 and 826 microSiemens per centimeter (µS/cm). Groundwater analytical results indicated that no PCP, VOC, or EPH constituents were detected at or above laboratory practical quantitation limits (Table 7 in Attachment B). Arsenic and barium were detected in the groundwater samples but concentrations were well below their respective MDEQ human health standards. 4.0 CONCLUSIONS AND RECOMMENDATIONS Tetra Tech excavated several test pits and sampled groundwater at the Site to evaluate potential impacts from historic use. Test pits were excavated along the railroad spur, within the former UST area, and within the wastewater infiltration pit. With the exception of benign debris encountered in the UST area and in the INF1 excavation, no other debris, staining, or odors were observed that would indicate a possible source of contamination in the areas investigated. Analytical results indicated that arsenic was detected in the soil samples collected from the INF2 excavation. Concentrations did not exceed MDEQ’s arsenic action level but did exceed the leaching to groundwater soil screening level. However, groundwater results for the closest piezometer (LP-5) exhibited concentrations of arsenic well below MDEQ’s human health standard. Therefore, arsenic in soil does not appear to be leaching to groundwater at concentrations that would result in potential affects to human health or the environment. Tetra Tech does not recommend further investigation of the Site based on the information obtained during this Phase II ESA. 5.0 LIMITATIONS It should be understood that this Phase II soil investigation will not produce scientific certainties that there is no petroleum products or hazardous materials that remains at the Site or that there are no impacts to soil and/or groundwater from past or recent uses of the property. The scope of work for this project was developed based on the information gathered during the Phase I ESA. This information was used to guide our professional judgment and make decisions as to a best possible course of action to investigate the property in the attempt to confirm or deny whether contamination or potential contamination exists at the property and to meet the objectives of this Phase II investigation. Our field observations were documented and soil samples submitted for laboratory analysis in an attempt to reduce uncertainties regarding contamination in the areas investigated under this Phase II investigation. Additional investigation may be required if additional information becomes available in the future that suggests other possible sources of contamination are present at the property.

Dated April 2005. Value exceeds leaching to groundwater soil screening level. a - Soil screening levels (SSLs) are based on EPA Region 9 Soil Screening Levels (dated April 2012) and as per DEQ's soil screening process (Attachment C, Part 1 - Direct Exposure, dated April 2012,http://www.deq.mt.gov/StateSuperfund/FrequentlyAskedQuestions.mcpx). EPA Regional Screening Levels (RSLs) for non-carcinogenic compounds were divided by 10 to account for a Dilution Attenuation Factor (DAF) of 10. EPA RSLs for carcinogenic compounds were not adjusted. b - Calculated soil screening levels for groundwater protection were developed as per DEQ's soil screening process (Attachment C, Part 2 - Leaching to Groundwater, dated April 2012 http://www.deq.mt.gov/StateSuperfund/FrequentlyAskedQuestions.mcpx). Calculation equation for groundwater protection (adjustment of risk-based soil screening level (RBSSL)) is as follows: RBSSL for Groundwater Protection from EPA RSL table x (DEQ's Human Health Standard from Circular DEQ-7 / EPA's Tapwater RSL from EPA RSL table) x 10. Where a Human Health Standard was not available, EPA's Maximum Contaminant Level was used. c - Values obtained from Montana DEQ's Montana Tier 1 Risk-Based Corrective Action Guidance for Petroleum Releases, dated September 2009. Values are based on a depth to groundwater of less than 10 feet (between the sample collection depth and groundwater).
