931 BROADWAY SEPA 016 - 008 - TEUTSCH PARTNERS Land Use Decision Documents 2025-04-22

petroleum impacts were detected in the soil beneath the site in 1991. The precise location of the release could not be determined. However, the property immediately west of the Property was not redeveloped for use by Everett Community College until after 1994. Therefore, the reported release was located in the former footprint of Everett Community College, which is located at least 375 feet west of the Property. Considering the separation distance of the reported release, Everett Community College does not constitute a potential issue of environmental concern. • Time Oil Station 168, located at 928 North Broadway Avenue, approximately 215 feet northeast of the Property, is listed on the CSCSL NFA, UST, VCP, and ICR databases. Gasoline-range petroleum hydrocarbons (GRPH), benzene, toluene, ethylbenzene, and xylenes (BTEX) were detected in the soil and groundwater beneath the site. PBS excavated and removed approximately 5,600 cubic yards of petroleum contaminated soil in 2011. Approximately 4,000 gallons of water were pumped from the excavation and discharged to the sanitary sewer. Approximately 3.5 cubic yards of benzene-contaminated soil remains on the site. The benzene remaining on the site is capped behind a retaining wall and beneath the North Broadway right- of-way. A determination of No Further Action was issued for the property in 2012. Considering the regulatory closure and the separation distance, the Time Oil site does not constitute a potential issue of environmental concern. • Mr. Tom Chin, located at 1021 North Broadway Avenue approximately 275 feet southeast of the Property, is listed in the CSCSL NFA, INST CONTROL, VCP, and UST databases. One gasoline UST and one waste oil UST were removed from the site in 1990. GRPH, diesel-range petroleum hydrocarbons (DRPH), and ORPH were detected in the soil beneath the site in 2004. Soil contamination was limited to the uppermost 50 feet of soil beneath the site and groundwater beneath the site was not impacted. After a restrictive covenant was recorded for the site, a determination of No Further Action was issued by Ecology in 2004. A periodic review conducted in 2010 indicated that the asphalt capping of the remaining contamination was protective of human health. Considering the regulatory closure and the separation distance from the Property,this site does not constitute a potential issue of environmental concern. Regulatory records were reviewed for the nearby sites. The records reviewed were sufficient to assess the potential risk of the listed sites. Potential issues of environmental concerns related to vapor encroachment were not identified in our review of regulatory records. 6.0 PROPERTY RECONNAISSANCE Mr. Travis Zandi, a SoundEarth Staff Scientist, visited the Property on February 6, 2015, to review conditions and land use practices on the Property and on adjoining and nearby properties. SoundEarth was unescorted during the Property reconnaissance. Interior access was not provided to the on- Property building. However, considering the residential nature of the Property, the lack of interior access is not expected to affect the findings or conclusions of the report. The purpose of the Property reconnaissance was to identify readily apparent indications of hazardous or potentially hazardous substances or petroleum products that were historically or are currently used, generated, stored, or disposed of on the Property. Selected photographs taken during the Property reconnaissance are included as an attachment to this report. SoundEarth Strategies,Inc. 10 February 16,2015
