SITE HAZARD ASSESSMENT WORKSHEET 1 Summary Score Sheet SITE INFORMATION: Name: J & J Salvage Drums Address: 832 73rd Ave SE, Olympia, WA 98501 Section/Township/Range: S2/T17N/R2W Latitude/Longitude: 46.982, -122.893 (46.981824, -122.892770 is closer to actual location) Parcel Number: 12702430100 Ecology FSID: 6719 Date Scored: November 24, 2015 Site assessed/ranked for the February 2016 update. SITE DESCRIPTION/HISTORY: This parcel (ID#12702430100) is located at 832 73rd Ave SE in Olympia, Washington in Thurston County just south of Tumwater and about a half of a mile northeast of the Olympia Regional Airport. This rectangular parcel is stretched between Tumwater Boulevard SE and 73rd Ave SE and encompasses almost 9 acres (8.69). In the southern end of this parcel, 73rd Ave SE intersects this lot and isolates a small triangle of land on the southern side. This property slopes south towards a 20-acre Swamp Lake which directly borders the property. The slopes in the area range from 0 to 15%. This parcel is zoned for residential, sensitive resource (most likely referring to the wetland), and light industrial uses. The surrounding area is generally composed of residential parcels (a mix of larger and or subdivided parcels) and light industrial uses. Soils type is listed as Indianola loamy sand. According to DOE’s database, 12 wells have at one point existed on this site. These include six currently active resource protection wells and six decommissioned wells. The shallowest resource protection well is 12 feet deep. No other information is available regarding these wells or any related sampling. Notes indicate that before the 1980’s, the site operated as an auto wrecking yard. By 1984, Jim Chapman bought the existing business and by the late 1990’s, the site was known as J&J Metals. J&J Metals operated as a scrap metal business and only accepted vehicles if all their fluids had been drained. On site metals were segregated into categories and sold to the public or commercial recyclers. By 2009, the long-time owner, James Chapman, had passed away. The family had closed the business and started cleaning up the site. It was stated by Colin Chapman, the property owner’s son, that they had removed more than 700 tons of scrap metal, 15 tons of garbage, and approximately 15,000 automobile and truck tires (the latter funded by an Ecology program) during initial site cleanup. The plan for the property was to clean up the site, have an Environmental Site Assessment (ESA) completed, and then sell the property. No information about an ESA on this site was found. County records show that in March 2012, the property changed ownership from the Chapman family to the Taylor family, with unknown relation to the original family. PREVIOUS INVESTIGATIONS: Between 1994 and 1999, the Thurston County Environmental Health Department conducted numerous inspections of J&J Metals. During these inspections secondary containment was installed around numerous hazardous waste storage areas and a contractor was hired to remove some oil-contaminated soils. Over the years, these inspections identified the following materials stored on site: lead-acid batteries, motor oil, PCB ballasts, light fixtures, and mineral oil. There are no inspection reports, photos, or business descriptions for when the property operated as a wrecking yard. On April 21, 2009, Thurston County Environmental Health Department conducted an initial investigation (ERTS #612367) that originated from staff identifying approximately a dozen partially buried drums on the property while inspecting the site. These drums are located in the very southern section of this parcel, on the south side of 73rd Ave SE, in the edge of the wetland. Most of the drums were completely rusted through and suspected to be very old. The few drums that contained liquids appeared to contain only rainwater. No odors, stains, or petroleum-like sheens were 1 observed in the immediate area, and there was no evidence of stressed vegetation. Due to the nature of the scrap metal business, there is a high risk that these drums were not empty when buried, as their metal would have been seen as a commodity. Due to the potential for subsurface contamination, this Initial Investigation recommended that the site be listed on Ecology’s Confirmed and Suspected Contaminated Sites List, and the suspected contaminate was listed as most likely being a petroleum product. It was stated, however, to hold off on the Site Hazard Assessment until after the ESA be conducted, but prior to sale. This SHA is being conducted as no copies of an ESA were received. A site inspection was conducted in May 2015. No property access was obtained (no one was present on site), and only what was visible of the fenced property from the road could be observed. The property itself appeared to have had all solid waste removed and the partially buried drums were still visible south of the roadway. Building structures on the south side of the property remained. Photos taken on 4/21/2009 during the Intial Investigation conducted by the Thurston County Environmental Health Department. 2 CONCLUSION: Historically, this property has been used as a wrecking yard before the 1980’s and later as a scrap metal business through 2012. Though it appears that most of the metals and other debris have been removed from this property, no Environmental Site Assessment or other sampling report have been received. Contamination potential remains high from both the past wrecking yard use (Arsenic, Cadmium, Chromium, Mercury, Lead, and petroleum constituents), and from approximately a dozen rusted out 55-gallon barrels partially buried by the wetland (most likely a petroleum constituent). Other contamination potential exists from other historical site activities, such storage of mineral oil and PCB in transformers. SPECIAL CONSIDERATIONS: Contamination presence and type is unknown and unconfirmed.
