The western portion of the site is improved with two adjoining buildings, which include an approximate 16,470-square-foot building with a showroom, offices, parts area, and middle storage area, and an approximate 16,480-square-foot attached main shop room (northern portion). These buildings, collectively referred to as the Bryant Building, are owned and operated as an automotive parts facility by Bryant Motors, Inc. (Bryant). The eastern portion of the site is developed with a parking lot with a concrete foundation in the south portion, a concrete foundation and asphalt parking in the middle portion currently occupied by a trailer-mounted telecommunications tower, and a grass area located in the north portion. The site is divided east and west by an asphalt paved alley. Appendix A includes a topographic map showing the site location as Exhibit 1, a site diagram as Exhibit 2, and a detailed diagram of the southwestern portion of the site as Exhibit 3. Terracon performed a Phase I Environmental Site Assessment (ESA) of the site for Rhodes Architecture + Light (Terracon Project No. 81187129), dated April 18, 2018. Based on the findings of the ESA, the site was occupied with residential lots from at least 1927 until the construction of two gas stations on the southwest and southeast corners of the site by at least 1943. The site underwent demolition of several residential structures, which were reportedly heated by oil, and was improved with commercial buildings and parking lots by 1965. The gas stations were removed by at least 1968 and buildings on the western portion of the site were replaced by the Bryant Building. After the remaining residential structures in the northeast corner of the site were removed by at least 1985, the eastern portion of the site underwent various phases of renovation and remodeling until the removal of all buildings by at least 2011. Based on the findings of our ESA, the following Recognized Environmental Conditions (RECs) were identified in connection with the site:  The Bryant Building was reported with multiple underground storage tanks (USTs; e.g. heating oil, waste oil) which were decommissioned in place.  The main shop area of the Bryant Building is equipped with a waste oil subsurface vault.  The site was historically utilized for auto and parts sales with reported limited auto repair and painting operations. Additional operations included chemical/oil storage, spills, wash sumps, a hydraulic hoist with subsurface components, and a parts washer. Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 2  The site was equipped with four wash sumps located in the middle room and main shop area of the Bryant Building. Based on the duration of operations, proximity to auto repairs, and/or presence of an oil/water type separator, there is the potential for an undocumented release.  The site was formerly occupied by residential structures which were reportedly heated with oil burning furnaces that may have utilized USTs to store the fuel.  A gas station was identified in the southeast corner of the site. Two USTs were reportedly closed in place; however, reports documenting tank closure at these locations were not available.  The southwest corner of the site was historically a gas station. Although it was reported that at least one of the former USTs was removed, there was no assessment completed/provided to document the proper closure of the tanks and other associated features (e.g. vaults, hoists, waste oil tanks).  A former Texaco gasoline station, located at 1408 Bronson Way North, was identified on the east-adjoining property. The site had documented soil and groundwater impacts. Depth to groundwater at the facility was approximately 21 to 23 feet below ground surface (bgs), with a horizontal gradient toward the south. The former Texaco station received a No Further Action (NFA) determination from the Washington State Department of Ecology in October 2003. Based on the findings and conclusions of Terracon’s Phase I ESA, Terracon recommended that additional investigation be conducted to assess for releases associated with the above-referenced RECs. In general, the RECs are associated with four separate areas of the site. These four areas include 1) the Bryant Building 2) historical residences and a hotel located on the northeast and east-central portion of the site 3) the historical on-site gas stations located on or near the southeast corner of the site, and 4) the historical on-site gas station located on the southwest corner of the site. A geophysical survey was also performed at the site by Terracon under contract to Construction Industry Training Council (CITC) / Rhode Architecture + Light. However, for purposes of reporting and documentation, the findings and results of the survey have been included in this Limited Site Investigation (LSI) report. It should be noted that as of the issuance of Terracon’s Phase I ESA, regulatory files associated with the former Texaco gasoline station were not provided by the Washington State Department of Ecology for review. However, prior to the completion of this LSI, Ecology provided facility files, which are summarized below. Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 3 From 1996 through 2003 GeoEngineers conducted semi-annual groundwater monitoring sampling on several wells surrounding and on the Texaco property. The groundwater samples were analyzed for benzene, ethylbenzene, toluene, and xylenes (BTEX) and gasoline-range total petroleum hydrocarbons (TPH). Groundwater sampling events from September 2002 did not identify analytes above laboratory detection levels. In January 2003, GeoEngineers performed a UST tank removal on four former USTs located on the eastern portion of the Texaco property. The removal included the tanks, associated piping, and petroleum-impacted soil. The remedial excavation was advanced to a depth of approximately 14 feet bgs, and confirmation soil samples were taken from the limits of the excavation, final limits of the excavation underlying the former dispenser island and product piping, and from soil stockpiles generated during the remedial excavation. Groundwater was not observed at the excavated depth. Results from laboratory testing for BTEX and diesel-range, gasoline-range, and oil-range TPH identified additional affected media from areas around the USTs and a stockpile. Therefore, an additional 380 cubic yards was excavated and disposed of off-site. Final cleanup confirmation soil samples were taken and tested for the above listed analytes. Sampling results were non-detect or below Model Toxics Control Act (MTCA) Method A levels. The excavation was then backfilled with clean pea-gravel. Following the removal of the four USTs, GeoEngineers conducted a final groundwater monitoring event in March 2003. Collected samples did not identify BTEX compounds or gasoline-, diesel-, or oil-range TPH at concentrations exceeding regulatory action levels. The GeoEngineers’ groundwater monitoring reports from 1996 through 2003, the UST Removal report, and a Voluntary Cleanup Action application were submitted to Ecology in July 2003, and the property was granted an NFA status in October 2003. Despite the findings of our review of the Ecology-provided documents, Terracon conducted additional groundwater sampling down-gradient of and adjacent to the southeast-adjoining former Texaco gas station.

FIELD INVESTIGATION Terracon has a commitment to the safety of all its employees. As such, and in accordance with our Incident and Injury Free® safety goals, Terracon conducted the fieldwork under a site-specific health and safety plan developed for this project. Work was performed using the Occupational Safety and Health Administration (OSHA) Level D work attire consisting of hard hats, safety glasses, protective gloves, and protective boots. In an effort to locate underground utilities in the work area, Terracon contacted the Washington State Utility Notification Center to arrange for public underground utility clearance at the site. 3.1 Geophysical Survey On May 19, 2018, Terracon representative Kyle Bennett mobilized to the site with a subcontracted geophysical professional to perform the geophysical survey of selected portions of the site. The subcontractor utilized GPR survey methods to perform the survey. The purpose of the survey was to attempt to assess for the presence or location of possible tanks, dispenser islands and/or product piping, and/or suspect excavations or other UST related anomalies that may be present at the site. The survey areas are depicted on Exhibit 2 in Appendix A. The survey was performed in select areas within the Bryant Building (showroom/offices, parts area, middle room, and main shop) where documented USTs and ancillary equipment were located; the southwest and southeast portions of the site where former fueling stations and documented USTs were located; and the northeast portion of the site where former residences and a motel were located with documented heating oil use. The survey identified four anomalies with characteristic features indicative of a UST within the Bryant Building, all adjacent to potential associated fill ports that were observed by the Terracon representative. Specifically, one anomaly was identified in the parts room, two in the middle room, and one in the main shop. The anomalies varied in size and ranged from approximately 6-foot-by-8- foot to 8-foot-by-12-foot. All anomalies were identified at depths of approximately two feet bgs. The survey did not identify any anomalies associated with two suspect fill ports in the western portion of the parts area. A presumable change in soil density was identified in the vicinity of the southwestern gas station, in the approximate location where approximate 4,000- and 2,000-gallon USTs were reportedly decommissioned by removal. The survey did not identify any additional anomalies in the southwest and southeast portions of the site. It should be noted that due to the dense soils in the southeast portion of the site, GPR scanning depth was limited and it was reported the equipment could only scan to an approximate depth of three feet bgs. Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 6 The survey identified five anomalies in the northeast and east central portions of the site, which Terracon infers to be potential heating oil USTs, excavations and/or unknown anomalies. Specifically, four anomalies were identified in the vicinity of the former residences, and one anomaly was identified in the vicinity of the former motel. However, only one anomaly was determined to be characteristic of a UST anomaly, located in the northeast corner of the site. The identified anomalies were approximately 4-feet-by-6-feet long and approximately two feet bgs. The survey did not identify additional anomalies in the northeast and east central portions of the site. Based on the findings of the geophysical survey, the locations of numerous soil borings, discussed in Section 3.2, were situated in accessible areas in an attempt to assess for potential releases from identified USTs and/or anomalies. 3.2 Soil Sampling Field activities were performed, as access allowed, adjacent to the RECs and GPR anomalies mentioned above. Boring locations relative to site features are depicted on Exhibits 2 and 3 of Appendix A. Terracon field representative Jeff Dobbins mobilized to the site on May 16, 17, 18, and July 5 and 6, 2018 to oversee the drilling of 24 soil borings advanced at the site. The borings were completed by Holocene Drilling, a Washington State-licensed driller, using a direct-push drill rig. The 24 borings, identified as soil borings B1 through B24, were advanced using a direct-push sampler equipped with disposable acetate sample sleeves. Throughout the drilling operation, soil samples were obtained continuously (to the extent practical) from five-foot long pushes driven into the ground using a 32 hertz, percussion hammer. Three-foot long pushes were advanced in the parts area of the Bryant facility due to limited overhead space. The steel sampling tube was extracted from the hole and the liners were removed and split open. Non-disposable sampling equipment was cleaned using a non-phosphate soap wash and potable water rinse prior to the beginning of the project and before collecting each soil sample. Direct-push borings used to collect soil and groundwater samples were finished as temporary monitoring wells and advanced to depths of approximately 25 feet bgs. Borings used to collect only soil samples were advanced to depths of approximately 10 and 15 feet bgs, with the exception of soil borings B19 and B23, which were advanced to approximately 25 feet bgs. Terracon field-screened soil samples for organic vapors using a calibrated photoionization detector (PID). This device provides a direct reading in parts per million (ppm) isobutylene equivalents. Upon removal of the sampler from the borehole, Terracon placed a portion of each sample in a sealable plastic bag. After a stabilization period, Terracon screened the headspace above the soil using the PID. Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 7 In addition, select soils were field-screened by a sheen test by placing soil into a shallow bowl of water and observing if a sheen formed on the water’s surface. A field log of each boring was maintained, including the thickness and depth of each soil unit encountered and the depth to the uppermost water table. Soil samples were observed to document soil lithology, color, and moisture content. Soils were logged in general accordance with American Society for Testing and Materials (ASTM) Practice Designation D-2488, Standard Practice for Description of Soils (Visual-Manual Procedure). Exploration logs are included as Appendix C. The boring logs also include the field screening results for each soil boring. Soil samples were collected from the intervals with the highest PID readings and/or positive sheen test result. In the absence of field indications, soil samples were collected from the depth interval most likely to be impacted, and/or the capillary fringe. Samples were collected at depths of approximately 5.5 to 11 feet bgs in the vicinity of the waste oil vault and as composites from the remedial backfill in the excavation of the former hydraulic hoist. See Table 1 of Appendix B for sample depths in each soil boring. A total of 34 soil samples were collected and submitted for laboratory analysis. This included one each from borings B1, B3 through B7, and B9 through B18, two each from borings B2 and B20 through B24, and three each from borings B8 and B19. Soil samples were extracted by hand using disposable gloves and placed directly into laboratory-supplied glassware. Additional samples were collected from each boring, but not analyzed by the laboratory. Each sample container was labeled with the project number, date, time, boring number, and sample number. Sample containers were placed in a chilled cooler immediately after sampling, and subsequently transported to ALS Environmental, a Washington state-certified laboratory, under strict chain-of-custody procedures. 3.3 Temporary Groundwater Monitoring Wells and Groundwater Sampling Three soil borings located in the Bryant facility (B2, B4 & B5), two in the southeast gas station area (B9 & B10), and five in the southwest gas station area (B8, B20, B21, B22 & B24) were converted to temporary groundwater monitoring wells. The monitoring well locations are shown in Appendix A, Exhibits 2 and 3. The groundwater monitoring wells were constructed with the following materials:  Five feet of 3/4-inch diameter, 0.010-inch machine slotted poly-vinyl chloride (PVC) well screen with a threaded bottom cap;  A 3/4-inch diameter, threaded, flush-joint PVC riser pipe to surface; and  Pre-sieved 10/20 grade silica sand for annular sand pack around the well screen from the bottom of the boring to the top of the well screen.

Sample tubing intake depths were placed at approximately 23 feet bgs, the middle of the screened interval for each well. Purging of the temporary wells was attempted, as practical, based on groundwater recharge rates and volumes. Approximately 1 to 2 gallons of development water was removed from each well before groundwater appeared relatively free of sediment. The sample containers were labeled with the project number, date, time, and sample number and placed in a chilled cooler immediately after sampling. The sample containers were subsequently transported to ALS Environmental, a Washington state-certified laboratory, under strict chain-of- custody procedures. At the completion of field activities, the borings were decommissioned using bentonite chips and capped to approximately match the existing ground surface. RESULTS OF THE FIELD INVESTIGATION 4.1 Geology/Hydrogeology In general, Terracon encountered sandy gravely soils throughout the site. Fill of variable thickness (0 to 12 feet bgs) was found below concrete, asphalt, and grass surfaces. Tan silt grading downwards to gray and orange sand was encountered below the fill to depths of 5 to 18 feet bgs, below which an orange and brown gravel layer was encountered to boring termination depths. Groundwater was observed at depths of approximately 15.5 to 22 feet bgs. Soil stratigraphy for each boring is presented as boring logs in Appendix C. 4.2 Field Screening PID readings were not detected above 3.5 parts per million (ppm) in soil collected from 19 of the borings advanced on site. Higher PID readings were detected in soil boring B10 (14.8 ppm at 21 feet bgs) and in four soil borings advanced on the southwestern portion of the site. The latter included borings B8 (405.4 and 90.1 ppm at 22 and 23 feet bgs, respectively), B19 (11.5 to 369.2 ppm at 13 to 22 feet bgs), B20 (13.1 ppm at 22 feet bgs), and B21 (24.9 to 629.7 ppm at 16 to 22 feet bgs). Sheens and petroleum odors were also noted in soils collected from 13 to 23 feet bgs in borings B8, B19, B20, and B21 and in well purge water from boring B21. Field indications of possible chemical impacts were not noted in soils from the other 19 borings or in the well purge water from the other nine borings sampled for groundwater. The field screening results are summarized on the boring logs in Appendix C.

Soil and groundwater samples collected from the vicinity of the former southwest gas station (B8 & B19 through B24) were analyzed for gasoline-, diesel-, and oil-range TPH by Northwest Method NWTPH-Gx/Dx (quantitative), with select samples analyzed for lead by EPA Methods 200.8 and 6020. Soil samples analyzed for gasoline-range TPH were collected using EPA Method 5035 sampling kits. Samples collected from the vicinity of the waste oil vault (B1 & B2) and in the excavation backfill (B17 & B18) were analyzed for polychlorinated biphenyls (PCBs) by EPA Method 8082A and diesel-range TPH by Northwest Method NWTPH-Dx. Reported soil and groundwater concentrations were compared with the Ecology MTCA Method A Cleanup Levels for unrestricted land use, as applicable, established under Chapter 70.105D RCW and its implementing regulation, MTCA Chapter 173-340 WAC. Where a MTCA Method A Cleanup level has not been established for a particular compound, the respective MTCA Method B Cleanup Level for cancer/non-cancer direct contact is applied for comparison. Data packages were checked for completeness immediately upon receipt from the laboratory to ensure that data and QA/QC information requested were present. Data quality was assessed by considering holding times, surrogate recovery, method blanks, matrix spike and matrix spike duplicate recovery, and detection limits. Based upon our interpretation of quality control information provided by the laboratories, it is our opinion that the overall dataset is useable as qualified for the purposes of this LSI. The laboratory analytical reports and chain-of-custody record are attached as Appendix D. The following sections describe the results of the testing. 5.2 Soil Analytical Results Former Texaco Station Gasoline-, diesel-, and oil-range TPH and VOCs were not reported above laboratory method reporting limits (MRLs) in soil samples collected from the proximity of the Texaco Station formerly located on the east-adjoining property (borings B10 & B12). Bryant Building Gasoline-, diesel-, and oil-range TPH and/or VOCs were not reported above laboratory MRLs or respective MTCA cleanup levels in soil samples collected from the Bryant facility (B3 through B7). Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 10 Oil-range TPH was detected in soil samples from downgradient of the waste oil vault (boring B2) at concentrations of 130 mg/kg at 6 feet bgs and 140 mg/kg at 11 feet bgs and in composite soil samples from borings B17 and B18 in the excavation backfill at concentrations of 93 and 75 mg/kg, respectively. Concentrations of oil-range TPH detected in these soil samples are below the MTCA Method A cleanup level of 2,000 mg/kg. Historical Residences and Motel Gasoline-, diesel-, and oil-range TPH and VOCs were not reported above laboratory MRLs in soil samples collected from the vicinity of GPR anomalies in the former residences and motel area (B12 through B16). Southeast Gas Stations Gasoline-, diesel-, and oil-range TPH and VOCs were not reported above laboratory detection limits in soil samples collected from the southeast gas station area (borings B9 through B11). Southwest Gas Station In the vicinity of the southwest gas station, soil samples collected from borings B8, B19, B20, and B21 were reported with concentrations of gasoline-range TPH exceeding laboratory detection limits. With the exception of soil samples collected from B8 at 22.5 feet bgs and B21 at 21.5 feet bgs with concentrations of gasoline reported at 1,200 and 220 mg/kg, respectively, the samples were below MTCA Method A cleanup levels. The concentrations reported in B8 and B21 exceed the MTCA Method A cleanup level of 100 mg/kg. Diesel-range TPH, lead, and/or VOCs were reported above laboratory detection limits in B8, B19, and B21. However, these concentrations were all below their respective MCTA Method A cleanup levels. Gasoline-, diesel-, and oil-range TPH and VOCs were not detected above MRLs in samples collected from borings B22, B23, and B24. The soil analytical results are summarized in Table 1 of Appendix B. 5.3 Groundwater Analytical Results Former Texaco Station Gasoline-, diesel- and oil-range TPH, lead, VOCs, and/or PCBs were not reported above laboratory MRLs in groundwater samples collected from the proximity of the Texaco Station formerly located on the east-adjoining property (borings B10).

Southwest Gas Station Gasoline-, diesel-range TPH, and multiple VOCs were reported above laboratory MRLs in the groundwater sample collected from B21. With the exception of gasoline and diesel at concentrations of 1,700 µg/L and 560 µg/L, respectively, concentrations were below their respective MTCA cleanup levels. The reported gasoline and diesel concentrations exceed MTCA Method A groundwater cleanup levels of 1,000 µg/L and 500 µg/L, respectively. Gasoline-, diesel- and oil-range TPH, lead, VOCs, and/or PCBs were not reported above laboratory MRLs or their respective MTCA Method A cleanup levels in the remaining groundwater samples collected from the southwest gas station area (borings B8, B20, B22, B24). The groundwater analytical results are summarized in Table 2 of Appendix B. INVESTIGATION DERIVED WASTE One 55-gallon drum of drill cuttings and two drums (one 22-gallon, one 55-gallon) of monitoring well purge/equipment decontamination water were containerized during the field activities. The drums are currently staged onsite west of the trailer-mounted communications tower. The drums will be properly disposed by a licensed disposal facility. Once picked up and disposed, Terracon will forward the waste manifest to Client. FINDINGS AND CONCLUSIONS Based on the scope of services described in this report and subject to the limitations described herein, Terracon concludes the following. Bryant Building The geophysical survey completed within the Bryant Building, located on the western portion of the site, identified four USTs and two UST fill ports. A total of nine soil borings, three completed with temporary groundwater monitoring wells, were installed within the building. Subsurface soils and groundwater collected did not contain concentrations of the analyzed compounds above laboratory MRLs with the exception of oil-range TPH detections in borings B2, B17 and B18. Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 12 The groundwater sample collected from B2 did not have detections above laboratory MRLs. Based on these results, there does not appear to have been a significant release from the waste oil vault at this time. Although the two composite soil samples collected from the remedial backfill of the hydraulic hoist excavation contained oil-range TPH concentrations, based on the reported concentrations, it does not appear the fill soils contain oil-range TPH concentrations above cleanup levels. Based on the overall results of this investigation, it does not appear that there has been a significant release to this area of the site from the Bryant Building. However, as discussed above there are four documented USTs and potentially two additional USTs that were reportedly decommissioned in-place. Given our experience with similar features, there is the potential for localized impacts to be present in and around these USTs. Former Residences and Motel The geophysical survey completed in the vicinity of the former residences and motel, located on the northeastern portion of the site, identified five anomalies which could possibly be associated with a UST and/or former UST excavation. A total of five soil borings were completed in this portion of the site. Soil samples did not contain concentrations of the analyzed compounds above laboratory MRLs. Based on the overall results of this investigation in these areas, it does not appear that there has been a significant release to this area of the site from the anomalies identified in the northeastern portion of the site. Although specific indications of USTs or associated anomalies were not identified, there remains the potential for undocumented heating oil USTs to be present in association with the former residences and hotel. Southeastern Gas Station The geophysical survey completed in the vicinity of the gas station, located on the southeast portion of the site, did not identify any significant features other than utilities. A total of three soil borings, two of which were completed with temporary groundwater monitoring wells were installed in this area. Subsurface soils and groundwater collected did not contain concentrations of the analyzed compounds above laboratory MRLs. Based on the overall results of this investigation, it does not appear that there has been a significant release to this area of the site from the former gas station. Although impacts were not identified in this area of the site, a hydraulic hoist is still present on-site that could have contributed to a localized release. Furthermore, additional undocumented features, such as USTs and associated piping, may also still be present at uninvestigated areas in this portion of the site. Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 13 Former Texaco Station One soil boring also completed with temporary groundwater monitoring well was installed in a relative down-gradient location from the offsite former Texaco Station. Subsurface soils and groundwater collected did not contain concentrations of the analyzed compounds above laboratory MRLs. Based on the overall results of this investigation, it does not appear that off-site impacts, if present, have migrated onto the site in this area from the former Texaco Station. Southwest Gas Station The geophysical survey completed in the vicinity of the former gas station, located on the southwestern portion of the site, identified one anomaly likely associated with the prior USTs and associated excavation. Seven soil borings were completed in this portion of the site. Soil impacted with gasoline-range TPH above MTCA Method A cleanup levels was identified in soil borings B8 and B21, adjacent to and potentially downgradient of the area of the former gasoline station and former USTs. Soils that are interpreted as fill were encountered in boring B24 to a depth of approximately 12 feet bgs that Terracon infers to be backfill in the location of the UST excavation. Similar soils were not encountered in the other six borings in the vicinity of B24, suggesting they were advanced outside of the excavation area. Groundwater with gasoline- and diesel-range TPH was collected from boring B21. The four borings with gasoline impacts are located southwest and relatively down-gradient of the UST excavation. Based on these results a release of gasoline appears to have occurred in the vicinity of the southwest gas station, resulting in gasoline concentrations in soil and groundwater exceeding MTCA Method A cleanup levels. Given the depth of the soil impacts and their location, it is possible that the former on-site gasoline station and/or USTs are the source of these soil and groundwater impacts; however, the groundwater migration direction in this area of the site has not been established. Furthermore, due to the nature of sampling from temporary groundwater monitoring wells, which generally cannot be adequately developed and allowed to equilibrate within the screened groundwater zone, groundwater samples sometimes remain turbid. As a result, sample results could be biased high and may not be representative of actual groundwater quality, as chemical constituents are often adsorbed to suspended colloids, which are then detected by the laboratory, and result in elevated concentrations. Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 14 RECOMMENDATIONS Based on the findings of this investigation the three areas associated with the Bryant Motors Facility, the former residences and motel and the southeast gas stations, Terracon does not recommend any additional investigations at the site at this time. The USTs located in the Bryant facility and the potential USTs and associated piping associated with other areas of the site, if any are encountered during future site redevelopment, should be properly decommissioned in accordance with Washington State rules and regulations. In addition, the waste oil vault should be removed and if any releases to subsurface soils are encountered the soils should be properly managed in accordance with local rules and regulations. Furthermore, petroleum-impacted soils were documented and/or likely to be encountered at other locations at the site, such as in the vicinity of the on-site hoist. Additional petroleum impacted soils, if encountered, would presumably be associated with the historical use of the site with the residences/Bryant facility documented with heating oil, the former gasoline and service stations. It should be understood that any earthwork completed outside of the areas investigated could encounter additional petroleum-impacted soils, volumetric estimates of which cannot be estimated at this time. Where petroleum-impaired soils, USTs, hoists, vaults and/or remnants of former environmental or auto repair features are identified during site redevelopment, an environment professional should be contacted to quantify and qualify the impacts. Terracon recommends that an environmental media management plan (EMMP) be prepared for the site to address impacts that could be encountered during any future earthwork activities conducted at the site. The EMMP will include guidance to the earthwork contractor for the following: health and safety; general contractor/subcontractor environmental qualifications; equipment decontamination; worker exposure, monitoring and field screening of soils; excavation and stockpiling of impacted soils; soil segregation; soil sampling methodology and frequency of testing; remedial excavations; disposition of excavation spoils; dewatering procedures of potentially impacted groundwater; disposition of impacted groundwater (if encountered); and documentation and reporting. Based on the findings of the investigation in the vicinity of the southwest gas station, Terracon recommends additional site investigation to assess options for regulatory closure. To further evaluate the extent and magnitude of the documented release of gasoline- and diesel-range TPH, we recommend installing permanent groundwater monitoring wells to determine the direction of groundwater migration and to collect groundwater samples. Additionally, with the known TPH soil impacts onsite, we recommend that the Ecology Guidance for Remediation of Petroleum Contaminated Soils, Toxics Cleanup Program, Publication No. 10- Limited Site Investigation CITC Headquarters and Training Facility ■ Renton, Washington August 8, 2018 ■ Terracon Project No. 81187232 Responsive ■ Resourceful ■ Reliable 15 09-057 Revised June 2016 be followed for the proper guidelines for reuse onsite or disposal of any petroleum-contaminated soil. With regards to the identified releases to soil exhibiting gasoline-range TPH concentrations above MTCA action levels, a release report to Ecology is required per MTCA (Washington Administrative Code (WAC) 173-340-300 (2) (a)), which states: “Any owner or operator, who has information that a hazardous substance has been released to the environment at the owner’s or operator’s facility and may be a threat to human health or the environment, shall report such information to the department within 90 days of discovery.” APPENDIX A – EXHIBITS TOPOGRAPHIC MAP Construction Industry Training Council
