5 . INTRODUCTION This report presents the results of the Removal Assessment (RA) completed under Task Order -3-3 of Geosyntec s contract with the Oregon Department of Environmental Quality (DEQ) for the former Richards Cleaners located at 63 SE Lyon Street, Albany, Oregon (Site). The general Site location is shown in Figure, and the Site layout is shown in Figure. The purpose of this RA was to: Decommission, via over-drilling, the existing groundwater monitoring wells at the Site. Characterize the surface soils beneath former buildings on the Site. Compare contaminant of interest (COI) concentrations to the DEQ s Risk Based Concentrations (RBCs) for complete exposure pathways. Provide recommendations for additional work, if necessary. Provide for disposal of investigation derived waste (IDW).. SITE DESCRIPTION AND BACKGROUND The Site formerly included two buildings, one occupied by a dry cleaning facility (Richards Cleaners) and a second by a garage (White Garage). A paved parking lot and grass area separated the structures (Figure ). The dry cleaning facility, most recently under the name Richards Cleaners, had operated as a dry cleaner since 934. Initially, Stoddard solvents may have been used in the dry cleaning process. After 969, when the building was reconstructed, tetrachloroethene (PCE) was reportedly used in the dry cleaning process and was stored a cleaning tank and drum in the building. In 994, an addition was added to the building and the solvent delivery was reportedly upgraded to a closed loop system. The White Garage at 7 7th Avenue SE was developed as a showroom and repair building for an automobile dealership in 95. The building was utilized as the showroom for the former Rallston Dodge dealership until the 960s. After about 965, the garage was used as storage, and was formerly utilized by Richards Cleaners for storage of equipment (steam presses, laundry machines), lawn mowers, office records, unused wastewater filters, and household cleaners. The City of Albany s (City) Fire Department Fire Station # (Fire Station) is located immediately to the north of the Site. The Fire Station building and lot are expected to be expanded to accommodate a larger facility. The properties on which Richards Cleaners and the White Garage reside have been acquired as part of the expansion (Appendix A).. Previous Environmental Investigations The following sections provide a brief summary of the historical environmental investigations at the Site. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx

6 .. City of Albany Sewer Sampling In November 0, the City informed the DEQ that PCE was detected in the sanitary sewer main beneath Lyon Street, near where the Richard s Cleaners sanitary sewer line connects to the sewer main. PCE was detected at a concentration of 9 micrograms per liter (μg/l) in a water sample collected from the sewer line. Trichloroethene (TCE) and cis-,-dichloroethene (cis-,-dce) were also detected in the water sample. The City reported that video from the sewer main indicated that the pipe had been damaged, possibly by chemical degradation of the composition pipe by solvents. The video also indicated that the damaged pipe was broken in one or more places, which could allow pipe contents to leak, or possibly allow groundwater to enter the pipe. According to the City, there are no other active sewer connections to the sewer main upstream of the Richards' connection... Cascade Earth Sciences Phase I/II ESA January 04 In 03, the City applied for and received a Brownfield Redevelopment Grant from the Oregon Business Development Department to conduct a Phase I Environmental Site Assessment (ESA) and limited Phase II ESA at the existing Fire Station and surrounding properties (including Richards Cleaners). In 03, the City hired Cascade Earth Sciences (CES) to complete a Phase I ESA. The Phase I ESA identified the following recognized environmental conditions (RECs) at the Site: Use of PCE at Richards Cleaners; Small amounts of paint and solvent degreaser in the White Garage; The use of an above ground storage tank (AST) at the Richards Cleaners site to store PCE; 55-gallon drums of PCE waste at Richards Cleaners; and Floor drains in both Richards Cleaners and the White Garage. In February 04, CES conducted a limited Phase II ESA to investigate the RECs identified in the Phase I ESA. The 04 investigation found PCE and daughter products TCE and cis-,- DCE in shallow soil and groundwater in the vicinity of the Site. A sample of sediment from a floor drain inside the garage was also found to contain PCE at a concentration of 4,000 milligrams per kilogram (mg/kg). The sample of the floor drain sediments also contained total lead at a concentration of,000 mg/kg. There are no records indicating the drainage destination of the drain. Low levels of petroleum hydrocarbons were detected in one soil sample collected on the Fire Station property (CES, 04a). 49_FINAL_RichardsCleaners_RemovalAssessment_ docx

7 ..3 CES Site Investigations June 04 CES returned to the Site on June 3, 04 and completed seven additional borings at the Site. Soil and groundwater samples were collected and analyzed for halogenated volatile organic compounds (HVOCs). PCE and daughter products were detected in groundwater from all seven borings in concentrations ranging from 8 to 900 micrograms per liter (μg/l). None of the soil samples contained PCE above method reporting limits (MRLs), but cis-,-dce was detected in one soil sample at a concentration of 0.5 mg/kg (RC-05 at feet depth)...4 Geosyntec Data Gaps Assessment In late 04, Geosyntec completed a Data Gaps Assessment Report for the Site which included a review of the previous environmental investigations, the additional sampling of soil and groundwater, and the installation of five monitoring wells. Additional groundwater monitoring was completed in January and April 05 (Geosyntec 05a, b). The results of the Data Gaps Assessment indicated shallow groundwater contained concentrations of PCE and associated daughter products, and that the lateral extent of VOCcontaminated groundwater was not fully delineated to the west, south, and east. Soil samples were collected from across the Site, but soils underneath Richards Cleaners building were not sampled. PCE and TCE were detected in a sediment sample collected from within the -inch floor drain located in the southeast corner of the White Garage; however, PCE and TCE were not detected in soil samples collected in the vicinity of the drain from a boring extended beneath the building The source of VOCs in groundwater to the west of the White Garage was not identified, but may be attributed to a subsurface pipe break or dry well associated with this drain. Stoddard solvents were not identified in soil and groundwater samples collected, although gasoline impacts did appear in select groundwater samples. The source of PCE detected in groundwater was deemed likely to be the result of dry cleaning solvents from a leaking pipe, possibly the broken sanitary sewer line discovered by the City, and/or a historic release to soil. Based on the distribution of VOCs in groundwater, there may have been more than one origin of release that impacted the area to the south of the Richards Cleaners building. The local groundwater gradient measured in October 04 was generally flat (<0.08 feet/feet [ft/ft] across the Site), although there appeared to be a slight northeasterly groundwater flow direction. The groundwater gradient April 05 was less than 0. ft/ft to the northwest. Depths to groundwater were between 4 and 6 feet below ground surface (bgs). Groundwater samples were collected from monitoring wells screened at 5 to 5 feet (MW-, MW-, MW-4, MW-5) and 0 to 0 feet (MW-3) (Figure ). VOC concentrations in groundwater were highest near the Richards Cleaners building (MW- and MW-4) and significantly lower in down gradient wells to the northeast (MW-3) and northwest (MW-). VOCs detected in groundwater in the south/southeast portion of the Site 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 3

8 (MW-5) may be the result of diffusion and/or seasonal fluctuations in groundwater flow direction. A No Longer Contained-In Determination (NLCI) was issued by the DEQ on October 3, 04, for soil and groundwater IDW generated during the installation of monitoring wells and soil borings. An addendum to the NLCI was issued on November 30, 05, to extend the findings of the NLCI to include the monitoring well decommissioning.. Site Visit and Scoping Meeting On November 7, 05, a planning meeting at the Albany City Hall was attended by Don Hanson (DEQ Project Manager), Mike Kucinski (DEQ Western Region Cleanup Manager), John Bradner (Albany Fire Chief), Kristin Preston (City of Albany Wastewater Superintendent), Chris Bailey (Albany Public Works Director), Staci Belcastro (Albany City Engineer), Jeff Woodward (DEA, Inc., City of Albany Owner's Representative), and Erin Dunbar (Geosyntec Task Order Manager). The purpose of the meeting was to discuss the schedule for the Fire Station expansion and the demolition of the Richards Cleaners, White Garage and Fire Station buildings, as well as monitoring well decommissioning. Final site plans and building design were evaluated in context of potential risks associated with soil and groundwater contamination. The plans for the expansion of the Fire Station show that a parking lot will cover the former Richards Cleaners and White Garage building locations (Appendix A). Additional sampling locations for this RA were located specifically to obtain data to further evaluate these potential future risks..3 Building Demolition Demolition of the Site buildings began in early 06 with the removal of the Richards Cleaners building completed on January 4, 06. After removal, the footprint of the former Richards Cleaners building was covered with gravel. A wood salvage operation at the White Garage and above ground demolition was completed by February 5, 06; however, the concrete foundation, driveway and garage slabs of the White Garage were left in place during the February 06 work. The demolition of the Fire Station began in June 06 and during the demolition of the Fire Station, the concrete from the White Garage was also removed. 3. REMOVAL ASSESSMENT ACTIVITIES The RA activities are organized into four general tasks consisting of: ) pre-field activities; ) monitoring well decommissioning; 3) test pit excavation and soil sampling; and 4) reporting. A photograph log of the RA activities is included in Appendix B. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 4

9 3. Pre-field activities Several actions were necessary in order to prepare for the RA field activities. The activities are described below: Coordinated with the City of Albany and Albany Fire Department regarding access, demolition schedules and site design; Called in a public utility locate through the State One Call service; Coordinated with ESC Laboratory Sciences (ESC), the State of Oregon contract analytical laboratory, for analytical testing of soil samples; and Contracted with Stratus Corporation, Inc. (Stratus) to decommission the monitoring wells, complete the test pits and IDW management and disposal. 3. Monitoring Well Decommissioning The monitoring well decommissioning activities were completed on December, 05, prior to the building demolition work (discussed in Section.). The five monitoring wells (MW- through MW-5) were removed by over-drilling with a.5- inch core using a Geoprobe 78DT direct-push drilling rig to a depth of 5 feet bgs (MW-3) or 6 feet bgs (MW, MW, MW4 and MW5). Boreholes were backfilled with hydrated bentonite chips up to feet bgs, then concrete to the surface per Oregon Water Resources Department (OWRD) requirements. Monuments were left in place for MW, MW, MW3, and MW4. The decommissioning well logs are included in Appendix C. Prior to removal of the monitoring well, a final depth to water was recorded. Table shows the final and historical depth to groundwater readings for the decommissioned groundwater monitoring wells. IDW generated during the monitoring well decommissioning included potentially contaminated soil and solid waste (e.g. core liners, well casing). At the completion of decommissioning, the IDW was drummed, transported offsite, and disposed at the Hillsboro Landfill on March 4, 06. Appendix D contains a copy of the disposal receipts. Decontamination water was disposed into the sanitary sewer system from within the Fire Station building with pre-approval from the City of Albany (December 3, 05). A NLCI determination was conducted by DEQ which allowed disposal of the IDW as non-hazardous waste. A copy of the NLCI is included as Appendix D. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 5

10 3.3 Test Pit Excavation and Soil Sampling On June 0, 06, Geosyntec collected 8 soil samples from six test pits excavated within the footprints of the former buildings. Five test pits were excavated within the footprint of the former Richards Cleaners building, and one test pit was excavated within the footprint of the former White Garage. Figure shows the location and orientation of the test pits, and Appendix E includes the test pit logs. In general, the test pits were -feet wide by 6 to 8-feet long and ranged in depth from 3.5 to 8 feet bgs. Groundwater was not encountered during the excavations. TP was located within the footprint of the former Richards Cleaners to characterize soils where a future stormwater quality basin is planned. Three test pits were located near building features of the former Richards Cleaners: TP3 was located near a floor drain, TP4 was near the boiler room, and TP5 was near the dry cleaning equipment area. TP was located to cover an area of the building not previously sampled. During the removal of the concrete slab at the White Garage, the demolition contractors located an iron drainage pipe that was attached to a former floor drain. The iron drain pipe ran in an easterly direction, towards the neighboring property. It is our understanding that the demolition contractor cut the pipe at the property line. The location of the floor drain is shown on Figure. TP6 was located under the removed drainage pipe. 3.4 Inadvertent Discovery of Cultural Resources Don Hanson of the DEQ contacted the State Historic Preservation Office (SHPO) to notify them of the proposed excavation activity. SHPO responded on February 3, 06 that the Site has high probability for possessing archaeological sites and/or buried human remains and DEQ was advised to use extreme caution during ground disturbing activities. Appendix F contains a copy of the SHPO correspondence. On February 9, 06, the DEQ issued an Inadvertent Discovery Plan for Cultural Resources (IDP). A copy of the IDP is included in Appendix F. The IDP outlined the protocol for coordination in the event of inadvertent discovery, including an immediate stop work clause. A copy of the IDP was shared with Geosyntec and was present during test pit activities. No cultural resources were found during the completion of the test pits. 4. RESULTS Field sampling and laboratory analytical testing was completed in accordance with DEQ s Brownfields program Quality Assurance Project Plan (QAPP) dated October 0, 0. The following sections provide both the field and soil analytical results. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 6

11 4. Field Screening Results. Soils were field screened using a photoionization detector (PID) and sheen tested. Results of field screening are shown on the test pit logs (Appendix E) and discussed in Appendix G. Field observations were used to determine which soil samples would be submitted to the laboratory for chemical analysis. The following is a brief summary of the field observations: Blue-green to gray colored soils were observed in test pits TP, TP3, TP4 and TP5. The upper contact of this soil was approximately 3 feet bgs. TP4 was excavated to 8.5 feet to determine the lower contact of the blue-green to gray soils. The lower contact was found at approximately 8 feet deep; A petroleum odor was noted during the excavation at test pits TP3 and TP4; and Elevated PID readings (from 50 to,990 parts per million [ppm]) were encountered at test pits TP, TP, TP3 and TP4 at depths generally below 3 feet bgs. One shallow sample at TP (0.5 feet bgs) had a reading of 08 ppm but soils collected beneath this sample had low PID readings until 3 feet bgs. 4. Analytical Results Soil samples were submitted to ESC for analytical testing of one or more of the following analytes: Volatile organic compounds (VOCs) using Environmental Protection Agency (EPA) Method 860B. VOC samples were collected using EPA Method 5035, to minimize the potential for loss of volatiles. Hydrocarbon identification by Method NWTPH-HCID. Gasoline-range hydrocarbons by Method NWTPH-Gx. Diesel- and oil-range hydrocarbons by Method NWTPH-Dx. Copies of the laboratory report, chain-of-custody, and the data validation checklist and narrative are included in Appendix H. Goals for reported detection limits (RDLs) were based on the most conservative DEQ RBCs. Results of the data review indicated the data were acceptable for use in this report. 4.. Soil Sample Results Eighteen soil samples were submitted for analytical testing. Soil analytical results are summarized in Tables and NWTPH-HCID Results Gasoline-range hydrocarbons (C7-C) were detected in six of fifteen samples. Detected concentrations ranged from 3. to 4,0 milligrams per kilogram (mg/kg). 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 7

12 Diesel-range hydrocarbons (C-C4) were detected in four of fifteen samples. Detected concentrations ranged from 3.55 to 95. mg/kg. Motor-oil range hydrocarbons (C4-C30) were detected in five of fifteen samples. Detected concentrations ranged from 4.5 to 63 mg/kg. Mineral spirits, kerosene, #6 fuel oil, and hydraulic fluid were not detected in the fifteen samples NWTPH-Gx Results Gasoline-range hydrocarbons were detected in four of the seven samples. Detected concentrations ranged from 6.4 to 6,460 mg/kg NWTPH-Dx Results Diesel-range hydrocarbons were detected in three of the seven. Detected concentrations ranged from.7 to 45 mg/kg. Oil-range hydrocarbons were detected in three of the seven samples. Detected concentrations ranged from 4.3 to 8 mg/kg VOC Results VOCs were detected in each of the 7 samples submitted for analysis. In total, separate VOCs were detected. Table 3 provides a summary of each detection. 5. NATURE AND EXTENT OF CONTAMINATION The nature and extent of contamination was initially discussed in the Data Gap Assessment Report (Geosyntec, 04). The data generated during this investigation provided additional information on the extent of soil contamination. Since no additional groundwater data was collected, the nature and extent of contamination for groundwater has not changed. Below is a brief summary for both media. 5. Soil During the RA, contaminated soils were encountered in all six of the test pits with the highest concentrations being detected in TP3 and TP4. The borings completed during the Data Gaps Assessment in 04 did not encounter petroleum contaminated soil outside of the former building footprints. In general, the soil contamination appears to be limited to the former building footprint of the Richards Cleaners from depths ranging from 3 to 8 feet bgs. In addition, low level gasoline-range hydrocarbons were detected in TP6, beneath the White Garage. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 8

13 5. Groundwater The PCE, TCE, cis-,-dce, trans-,-dichloroethene (trans-,-dce), and chloroform were detected during the historical groundwater investigations. Based on the groundwater monitoring data to date, the PCE concentrations in groundwater appear to range from approximately 70 micrograms per liter (μg/l) at the south end of the Fire Station building to approximately 5 μg/l at the north end. Gasoline range hydrocarbons were detected at eight groundwater locations (boring and wells). The highest concentrations of gasoline were detected in the southwest corner of the Hasty Freez property, and decreased in concentration to the northeast. 5.3 Primary Sources of Contamination The source of TPH contamination identified in test pits from beneath both the Richards Cleaners Site and the White Garage have not been identified. The releases could be associated with former Site activities or unknown releases. The source of the PCE impacts in groundwater appears to be Richards Cleaners, from either leaking sewer lines and/or historic releases to soil. A sewer line from the cleaners is located along the north side of the building and was discovered to be leaking; the location where the line joins the City sewer main line in South Lyons Street and the junction was discovered to be damaged. In addition, PCE was detected in the water sample obtained from the main sewer line. 5.4 Contaminants of Interest To identify compounds detected in Site soil and groundwater that are most likely to be of concern to human health, detected concentrations of these contaminants were compared to a series of DEQ risk-based screening criteria that cover the range of potential human activities that may be practiced on the Site currently or in the future. Compounds with detected concentrations were identified as being COIs. It should be noted that the identification of COIs does not indicate that an unacceptable risk or that a threat exists. Also, COI identification does not necessarily indicate that remediation of a specific environmental media is required. Screening criteria are purposely conservative so chemicals that may contribute to Site risk can be further evaluated. The previous investigation identified the following COI for groundwater: PCE and daughter products TCE, cis-,-dce, and trans-,-dce, as well as chloroform. Based on the soil analytical data collected during this investigation COI for Site soils include gasoline-, diesel- and oil-range hydrocarbons, and VOCs. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 9

14 6. CONCEPTUAL SITE MODEL A CSM defines the potentially complete exposure pathways through which human or ecological receptors may be exposed to Site contaminants under current or anticipated future land use conditions. A CSM for the Site was developed by Geosyntec in the Data Gaps Assessment. Based on results of the RA, the CSM has been revised. An evaluation of current and reasonably likely future receptor-exposure pathway analysis is presented below. Figure 3 depicts the updated CSM. 6. Potential Receptors Potential human receptors are those individuals who might be likely exposed to the COIs under current and reasonably likely future land-use conditions. The Site and surrounding properties along Lyons Street are currently zoned for mixed use where commercial and residential land uses are permitted. The Site and properties to the north are included in the development of a new Fire Station for the City, where the Site will become a parking lot to serve the new Fire Station. Geosyntec assumes the new Fire Station is a long term investment for the City and the future land use is reasonably likely to continue as a Fire Station and not residential. Emergency personnel will be living at the Fire Station in shifts, 4-hours on-duty (on Site) and 48-hours off-duty (off Site). The exposure time for emergency personnel is less than that of the residential scenario, so the occupational exposure scenario is considered protective of emergency personnel periodically living on Site. Due to the future Site use as a Fire Station and emergency personnel not meeting residential scenario conditions, the residential pathway is not considered complete. A former Beneficial Land and Water Use Determination (BLWUD) was completed during the Data Gaps Assessment. Current and potential human receptors that have been identified in the risk based screening include the following: Adults in the occupational scenario; Adults in the construction scenario; and Adults in an excavation worker scenario. 6. Potential Ecological Receptors Ecological receptors are not anticipated since there is no ecological habitat present on the Site. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 0

15 6.3 Exposure Pathways for Soil: Soil ingestion, dermal contact, and inhalation: The exposure pathways are considered potentially complete for occupational, construction and excavation workers. Volatilization to outdoor air: The exposure pathway is considered potentially complete for occupational workers. Vapor intrusion into buildings: The exposure pathway is considered potentially complete for occupational workers. Leaching to groundwater: This exposure pathway considers soil leaching to groundwater used for tap water and is incomplete due the presence of municipal water supply to the Site and surrounding areas, and the unlikelihood of shallow groundwater use in the future. 6.4 Exposure Pathways for Groundwater: The following summarizes the potential exposure pathways for groundwater. Ingestion and inhalation from tap water: These exposure pathways are considered incomplete because the Site and surrounding areas receive drinking water from a municipal supply, and the unlikelihood of shallow groundwater use in the future. Volatilization to Outdoor Air: This exposure pathway is considered potentially complete for occupational receptors. Vapor intrusion into buildings: This pathway is considered potentially complete for occupational receptors. Direct contact and inhalation, groundwater in excavation: This exposure pathway is considered potentially complete for construction and excavation workers. 7. RISK SCREENING Analytical results from data obtained during this RA were compared to the DEQ RBCs (November 05) for the applicable exposure pathways discussed in Section 6. The RBCs and results are summarized in Tables and 3. In summary, Gasoline-range petroleum hydrocarbons and low levels of VOCs were detected in soil; however, none of the detected concentrations exceeded the RBCs for occupational, construction, or excavation worker pathways. Emergency personnel who will be living in the new Fire Station on rotational shifts of 4 hours on duty and 48 hours off duty were evaluated under the occupational exposure pathway. The default occupational RBC calculations are based on adult exposure of 8 hour days for 50 days per year, which were modified for emergency personnel living at the Fire Station using an 49_FINAL_RichardsCleaners_RemovalAssessment_ docx

16 average 56 hours per week or approximately 5 days a year. Because the living quarters will be located on the second floor on the south side of the new Fire Station building, and emergency personnel living at the Fire Station will have minimal exposure risk to COIs through direct contact or ingestion, the vapor intrusion pathway was further evaluated. VOCs and gasoline COIs were below the modified occupational exposure RBCs for vapor intrusion to indoor air. 8. SUMMARY AND CONCLUSIONS This RA report provides a summary for field activities and analytical data collected from the 63 Lyons Street South, Albany, Oregon Site. The field activities included decommissioning five monitoring wells, completion of six test pits, and collection and laboratory analysis of soil samples. Based on the CSM, potentially complete exposure pathways include future construction and excavation workers and/or adults in the occupational scenario. The COIs on the Site include petroleum hydrocarbons and VOCs. In general, contamination was detected during this RA at depths up to 8 feet bgs and blue-green stained soil was observed between 3 and 8 feet bgs below the former Richards Cleaners building. Below the White Garage, contamination was detected to a depth of 3.5 feet bgs. The detected concentrations of COIs did not exceed applicable DEQ RBCs. Modified occupational RBCs were evaluated and indicate that emergency personnel living at the Fire Station are protected under the occupational use scenario. While there are COIs that exceed the leaching to groundwater RBC, the direct contact to groundwater pathway for human receptors is considered incomplete per the Data Gaps Assessment. The direct contact pathway is potentially complete for ecological receptors if the groundwater discharges to surface water; however, groundwater monitoring has shown that the shallow groundwater gradient is generally flat across the Site with a slight northeast or northwest gradient. TCE was not detected in groundwater monitoring wells in the northwest (MW-) or northeast (MW-3) of the Site during the April 05 monitoring event, and PCE concentrations were less than 3. µg/l. Based on these results, VOCs in groundwater do not appear to be migrating to down gradient monitoring wells at significant concentrations. The City initially discovered PCE in the sewer line beneath Lyon Street and further investigation of the sewer line showed that it was damaged and leaking. The sewer connection from the Former Richards Cleaners was found to be the source of the PCE. The damaged sewer line may act as a conduit for contaminant migration at the Site. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx

17 A stormwater quality basin will be located at the west end of the former Richards Cleaners, and a stormwater quality swale will be located along the east side of the former White Garage (Figure ). There is exposure risk to construction and excavation workers during the construction of these stormwater quality features. The basin design specifications indicate that construction and excavation workers could be excavating into contaminated soil. The completed stormwater quality structure will be covered with geotextile, drain rock, and a growing medium for vegetation. The stormwater from these basins will flow into the municipal stormwater system (Appendix A). 9. RECOMMENDATIONS Based on our findings, Geosyntec offers the following recommendations: A contaminated media management plan (CMMP) is recommended for the Site. The CMMP would include provisions for the safe handling of soils during Site redevelopment activities. Abandonment of the damaged sewer line in Lyons Street to prevent the line from acting as a conduit for future contaminant migration. Geosyntec also recommends that DEQ issue a No Further Action letter, assuming the land use will continue as a fire station with no residential use of the Site. 49_FINAL_RichardsCleaners_RemovalAssessment_ docx 3

68 APPENDIX F Inadvertent Discovery

69 February 3, 06 Mr. Dan Hanson Oregon DEQ 65 E 7th Ave Ste 00 Eugene, OR 9740 RE: SHPO Case No DEQ, Former Richards Cleaners Assessment 8 test pits 63 Lyon St (S 3W 7), Albany, Lincoln County Dear Mr. Hanson: Our office recently received a request to review your application for the project referenced above. In checking our statewide archaeological database, it appears that there have been no previous surveys completed near the proposed project area. However, the project area lies within an area generally perceived to have a high probability for possessing archaeological sites and/or buried human remains. In the absence of sufficient knowledge to predict the location of cultural resources within the project area, extreme caution is recommended during project related ground disturbing activities. Under state law (ORS and ORS 97.74) archaeological sites, objects and human remains are protected on both state public and private lands in Oregon. If archaeological objects or sites are discovered during construction, all activities should cease immediately until a professional archaeologist can evaluate the discovery. If you have not already done so, be sure to consult with all appropriate Indian tribes regarding your proposed project.

73 APPENDIX G Field Procedures

74 APPENDIX G FIELD PROCEDURES This appendix details the field procedures, field quality assurance/quality control (QA/QC) protocol, and the chemical testing program implemented during the monitoring well decommissioning and test pit excavation at Richards Cleaners. Field methods described in this appendix include: Decommissioning of monitoring wells; Collection of soil samples from open excavations; Field screening soil samples; Decontamination procedures; Handling of investigation derived waste (IDW); and Chain of Custody (COC) Procedures.. DECOMMISSIONING OF MONITORING WELLS Monitoring wells were decommissioned drilling using direct-push drilling equipment operated by Stratus Corporation, Inc. (Gaston, Oregon). As per Oregon Water Resources Department regulations (OWRD) existing monitoring wells were decommissioned in place by over-drilling the total depth of each well and backfilling with hydrated bentonite chips up to -feet below ground surface; the remaining depth was backfilled with concrete. Surface monuments for MW-MW4 were left in place and the monuments filled with concrete. The surface monument for MW5 was removed, the upper -feet backfilled with concrete, and covered with 3-inches of topsoil soil to match the surrounding ground surface. All drill cuttings and decontamination water was contained in a 55-gallon DOT-approved steel drums, labeled and taken offsite pending future disposal. The investigation-derived waste was disposed of at the Hillsboro Landfill on March 4, 06.. Decontamination Procedures The objective of the decontamination procedure was to minimize the potential for cross contamination between boring locations and between individual samples within a specific boring. Sampling or measurement equipment, including well purging equipment and water level measurement instruments, were decontaminated in accordance with the following procedures before each sampling attempt or measurement. Rinse with distilled water; Wash with nonphosphate detergent solution (Liquinox and potable tap water); and Rinse with distilled water. PNG069 G- July 06

75 . COLLECTION OF SOIL SAMPLES FROM OPEN EXCAVATIONS.. Soil Sampling Test pits were excavated for the purpose of soil sampling. Field personnel directed the backhoe operator on where to dig for the collection of soil samples. Soil samples were collected from the base of the excavation and each of the excavation sidewalls. Once the bucket reached the surface, the field manager removed the soils, observed, and recorded in field notes. Soils were classified using the United Soil Classification System (USCS) classification system. Moisture, color, density, apparent grain-size, and soil type were noted, along with the presence of groundwater, if encountered. Olfactory or visual indications of contamination were also noted. Soil samples selected for analytical testing were placed in laboratory-supplied containers, labeled, logged on a COC, and placed into a cooler with ice prior to delivery to the laboratory.. Field Screening Soil Samples Soils were field-screened using visual, sheen, and olfactory observations, and for the presence of volatile organic compounds (VOCs) using a photoionization detector (PID). Headspace vapor screening was made on representative samples placed in a sealed plastic bag. The tip of a MiniRae PID was inserted into a hole in the bag, and the presence of VOCs was measured. Readings are collected in parts per million (ppm). Notes on visual appearance, odor, and PID readings were recorded on the field notes boring log. Field screening results are site- and sample-specific. The results may vary with temperature, soil moisture content, soil type, and type of contaminant. The PID is designed to quantify VOC vapor concentrations in the range between ppm and,000 ppm with an accuracy of 0 percent of the reading and between,000 ppm and 0,000 ppm with an accuracy of 0 percent of the reading..3 Handling of Investigation-Derived Waste IDW, purge water, and soil cuttings from drilling were placed in 55-gallon drums. The drums were labeled with the project name, contents, and date. The drummed IDW was stored offsite pending future disposal. Disposable items, such as sample tubing, gloves and paper towels, were placed in plastic bags after use and disposed in municipal solid waste bins..4 Chain of Custody Procedures Samples obtained for chemical analysis were transferred into new sample containers supplied by the project analytical laboratory. The appropriate sample volume was obtained for the laboratory to complete the method-specific QC analyses. Possession of the samples was PNG069 G- July 06

Upon receipt of the samples at the laboratory, the following procedures were followed: ) the COC form was signed by the laboratory personnel; and ) the conditions of the samples were recorded. The original COC remained with the laboratory, and copies were returned to Geosyntec. PNG069 G-3 July 06

152 GLOSSARY OF TERMS ONE LAB. NATIONWIDE. Abbreviations and Definitions SDG MDL RDL U RPD (dry) Original Sample (S) Rec. Sample Delivery Group. Method Detection Limit. Reported Detection Limit. Not detected at the Reporting Limit (or MDL where applicable). Relative Percent Difference. Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. Recovery. Cp Tc 3 Ss 4 Cn 5 Sr 6 Qc Qualifier J J J3 J4 J5 J6 J7 V Description The identification of the analyte is acceptable; the reported value is an estimate. Surrogate recovery limits have been exceeded; values are outside upper control limits. The associated batch QC was outside the established quality control range for precision. The associated batch QC was outside the established quality control range for accuracy. The sample matrix interfered with the ability to make any accurate determination; spike value is high. The sample matrix interfered with the ability to make any accurate determination; spike value is low. Surrogate recovery cannot be used for control limit evaluation due to dilution. The sample concentration is too high to evaluate accurate spike recoveries. 7 Gl 8 Al 9 Sc ACCOUNT: PROJECT: SDG: DATE/TIME: PAGE: Oregon Dept. of Env. Quality - ODEQ PNG069 L /8/6 8:8 8:8 74 of 79
