1. SITE INFORMATION

Site Name: Delancey-Houghton Elementary School Assessment Location: Corner 4th Ave SE and Canna St S, Soap Lake, WA 98851 Tax Parcels: 080694012 through 080694018 Date of Sampling: December 14, 2015 SSID: 10ZZ Latitude: 47.385857 Longitude: -119.485848

The Delancey-Houghton Elementary School is located on the northwest corner of 4th Avenue SE and Canna Street S in Soap Lake, Washington (Figure 1). The site consists of an approximately 30,000 square foot abandoned former elementary school building with exterior walls, no roof, and few interior walls. The site is bounded to the west by the Soap Lake School District bus barn, to the south and east by residential homes, and to the north by the Soap Lake City Hall and the Soap Lake Police Department. The area surrounding the site is primarily residential, and the nearest residences are approximately 150 feet east and 180 feet south of the site (Figure 2).

2. PURPOSE The United States Environmental Protection Agency (EPA) tasked Ecology and Environment, Inc. (E & E), under Superfund Technical Assessment and Response Team (START) contract number EP-S7-13-07, Technical Direction Document number 15-12-0001, to assist EPA with assessment activities at the Delancey-Houghton Elementary School Assessment site in Soap Lake, Washington. The objectives of the project were to assess the site for a potential removal action and to assess the site for hazardous substances and potential pathways that could impact the environment and surrounding community with a focus on potential asbestos-containing material (ACM) and orphaned containers.

4. BACKGROUND The school was opened in 1947 with 171 students and expanded to add a library, multi-purpose room, and kitchen in 1950. A new elementary school was constructed adjacent to the existing high school at a different location in town sometime in the early 2000s, and it is not clear when the Delancey-Houghton Elementary school closed. Based on aerial photography, it appears that demolition of the building began sometime between 2009 and 2011. It is unknown when demolition activities ceased. According to the Grant County Assessor’s office, the parcels were transferred to Grant County Tax Title in 2013. In July 2015, Washington State Department of Ecology received an anonymous letter reporting the building to be without a roof or interior walls and the presence of “piles of removed pipe and wall asbestos on the premises that became airborne in the blowing wind.” The letter also notes several barrels of unknown chemicals leaking into the soil. The complainant expressed their concern that the building was being used by the homeless and was an attractive nuisance to children. Based on the alleged presence of ACM and the report of barrels of unknown chemicals, EPA and START mobilized to the site to assess the site for potential threats to human health and the environment.

5. ACTIVITIES EPA and START mobilized to the site on December 14, 2015. A site walk was conducted and potential ACM was identified for sampling. In addition, two metals drums and one plastic bucket were identified for sampling. Photographic documentation of the site visit and sampling event are provided in Attachment A. For descriptive purposes, the former school building was divided into three portions as follows (Figure 2): Basement: this portion of the school has few interior walls, no ceiling (with the exception of what

is suspected to be the former boiler room), and is covered in demolition debris including broken glass and boards with rusted nails;

Central: this portion of the school is completely demolished with only concrete footings remaining; and

Former gymnasium: this portion of the school is mostly intact with fire damage noted (the interior of this portion of the building was not entered due to safety concerns).

Twenty-three samples of potential asbestos-containing materials (ACM) were collected. The sampled materials are as follows. A pile of insulation that included small flakes of iridescent solids was located near the north entrance of the basement portion of the school in the former playground area (Figure 2). Two samples (IN01 and IN02) were collected of the material. Portions of 12-inch by12-inch cellulose acoustic ceiling tiles were also noted in the pile and one sample (CT01) was collected. One accessible window in the structure still contained the metal framing with small amounts of white glazing material. One sample (WG01) was collected of the glazing material. An entrance to the basement was discovered on the east side of the building and used to access the main portion of the building. Approximately 50 feet of waterlogged corrugated “air-cell” type thermal system insulation (TSI) was noted on the basement floor. Three samples (TS01 through TS03) were collected from three different sections of the TSI material. TS01 included an inner tar-paper type wrapping, and both TS01 and TS02 included the outer fabric wrapping. Ceiling tiles were noted to litter almost the entire surface of the basement floor. The tiles were in varying grades of degradation, from full tiles to miniscule pieces. It is estimated the ceiling tiles cover approximately 3,080 square feet of the floor of the basement. One sample (CT02) was collected from the tiles on the floor. These tiles may be the same type of tile sampled from the insulation pile on the north side of the building. The interior walls in the basement rooms were coated with lath and plaster which is a potential ACM. The lath and plaster also appeared to cover portions of the ceiling in several locations. A total of seven samples (LP01 through LP07) of the plaster were collected from various walls inside the basement. Also noted in the basement was a pile of pink gypsum board. No joint compound or surfacing was noted on this gypsum board, and one sample (GB01) was collected from the pile. No other features were noted or sampled in the basement. The central portion of the building has been completely demolished with the exception of concrete footings. This area did not appear to have any building materials of note. The former gymnasium is located west of the central area. Some vinyl tile was in place in the southern gymnasium entry way along with cove base, and one section of what appeared to be carpet backing. Samples of the vinyl tile and related black mastic (VT01), cove board and underlying brown mastic (CB02), and carpet backing (BC01) were collected from the entryway. One portion of the building, the former gymnasium, still had an intact roof. This portion of the structure evidenced fire damage and was not accessed because of health and safety concerns. There was a semi-exposed staircase on the northwest corner of the building. A sample of cove base with mastic (CB01) and stair tread (ST01) from the staircase and a sample of concrete flooring (CF01) were collected from the

stairwell. Another stairwell on the southwest corner of the building appeared to contain the same materials and no samples were collected from this stairwell. An approximately 3-foot square section of fiberboard with what appeared to be an asphaltic roofing tar was noted on the south lawn of the building. One sample (RF01) was collected of this material. Similar pieces of asphaltic roofing tar were noted on the lawn in this area.

One metal drum (Drum 1) was noted on the north side of the former gymnasium. The drum was partially dented and the bung rested on the top of the drum. The drum was approximately ¾ full of a brown oil-like substance, with a layer of what appeared to be water on top. One sample (DR01) was collected from the drum which consisted of the two distinct layers. One rusted metal drum (Drum 2) and a 5-gallon plastic container (Drum 3) were noted just inside the western entryway to the central portion of the site. The drum was approximately ½ full of a solidified material that could not be penetrated by a sampling tool, with approximately 2 inches of a water-like substance on the top. One sample (DR02) was collected of the water-like substance from the top of this drum. The plastic container was approximately ⅓ full of a blue-white granular material. One sample (DR03) was collected of the material.

All potential ACM samples were submitted to an off-site fixed laboratory for asbestos by polarized light microscopy (PLM) analysis. The data validation memorandum is provided in Attachment B. The samples from the drums were analyzed using First Step hazard categorization. A description of the samples collected from potential ACM and laboratory results are provided in Table 1. A description of the samples collected from the drums and First Step hazard categorization are provided in Table 2.

As summarized in Table 1, the results indicated that three of the potential ACM samples contained asbestos. Sample TS03, collected from a sample of TSI from the basement, contained 55% chrysotile asbestos. Samples IN01 and IN02, which were collected from the insulation pile, contained less than 1% actinolite asbestos, and the lab reported that the small iridescent flakes were vermiculite. The lab also reported that the vermiculite composed approximately 20% of each bulk sample, with the remainder composed of mineral wool. Based on a visual review of the insulation pile surface, these samples and the lab's estimate of the relative percentages of vermiculite and mineral wool appear to represent the composition of the pile as a whole. The remaining bulk samples did not contain asbestos.

The samples from the drums were analyzed using First Step hazard categorization and a field-portable First Defender instrument, and the results of the hazard categorization are summarized in Table 2. From Drum 1, the water-like layer (sample HC03) and the oil-like substance (sample HC04) were analyzed separately using the First Step method. The oil-like layer sample from Drum 1 (HC04) was determined, based on First Step and the First Defender instrument, to contain motor oil and to be flammable. The color of the oil-like layer was dark brown, which indicates that the material was likely waste oil, as clean motor oil is typically amber in color. The Bielstein test resulted in orange flames which indicates that the sample did not contain high concentrations of chlorine atoms; therefore the sample was not further assessed for the presence of polychlorinated biphenyls. The sample from the water-like layer (sample HC03) was determined through First Step to be a non-hazardous liquid not otherwise specified (n.o.s.) and was likely to be rainwater that had filtered into the drum through the open bung. The substance from Drum 2 (sample HC02) was determined through First Step to be a non-hazardous liquid n.o.s. and was likely rainwater that had filtered into the drum through the rusted top. The substance from Drum 3 (sample HC01) was determined to be a non-hazardous solid n.o.s., and analysis with the First Defender did not return any results from the instruments library.

6. SUMMARY AND CONCLUSIONSEPA and START mobilized to the site on December 14, 2015 and collected a total of 23 samples for asbestos by PLM analysis and three samples from abandoned drums for first step analysis.

Asbestos sample results indicate the presence of chrysotile in one TSI sample and actinolite and vermiculite in two insulation samples. During sampling, the three TSI samples appeared to be from a homogenous material type; however, given the significantly different analytical findings, they likely represent different types of material. Very small quantities of ACM TSI were noted during the sampling event (e.g. less than 1 square foot).

The insulation pile contained less than 1% asbestos (actinolite), and the lab reported that the iridescent flakes were vermiculite. The vermiculite and mineral wool are intermingled in the insulation pile such that it would be impracticable to segregate them. Given the limitations of currently used analytical methods for vermiculite, and the likelihood that the vermiculite may be from the Libby site in Montana, the insulation pile should be treated and managed as ACM. The volume of the insulation pile is estimated to be approximately 96 cubic feet of material (e.g. 12 feet long by 4 feet wide by 2 feet deep).

While no material similar to the insulation pile was observed in the basement portion of the building among the demolition debris, it is possible that the material may be located in areas of the basement that were not investigated, visible, or accessible. In addition, the former gymnasium was not inspected for health and safety reasons, and this area may also contain unidentified ACM. Based on these limitations, it is possible that additional ACM or materials containing asbestos may be present in these areas.

Results of the sampling of the drums indicates the Drum 1, which is located on the northern side of the former gymnasium, contains a hazardous material based on flammability. The other drum and bucket contain materials that did not exhibit hazardous characteristics.

The site also poses a physical threat with remnants of demolition debris including boards with rusted nails and glass and the fire-damaged former gymnasium. The site is accessible to anyone such as trespassers and passersby including children.
