21-101296-SEPA Checklist-05-12-2021-V1 SEPA Environmental checklist (WAC 197-11-960) April 2021 Page 1 of 34 Federal Way Public Schools 33330 8th Avenue South Federal Way, WA 98003 (253) 945-2000 Introduction The purpose of this Environmental Checklist is to identify and evaluate probable environmental impacts that could result from Federal Way Public Schools’ (FWPS) proposal and to identify measures to mitigate those impacts. FWPS proposal would involve the following: Demolish the existing Olympic View Elementary School and construct a new two story approximately 64,078 SF K-8 school. At this time construction is scheduled to begin in early spring 2022 with occupancy in Fall 2023. This Environmental Checklist provides additional, project-specific details concerning the proposal. The State Environmental Policy Act (SEPA) requires governmental agencies consider the environmental impacts of a proposal before the proposal is decided upon. This Environmental Checklist has been prepared in compliance with the State Environmental Policy Act; the SEPA Rules, effective April 4, 1984, as amended (Chapter 197-11, Washington Administrative Code); and Federal Way Public School District Policy No. 6890, which implements SEPA for the District. This document serves as SEPA review for site preparation work, grading/ excavation, building and site construction, and operation of the Olympic View K-8 School. Analysis contained in this Environmental Checklist is based on Design Plans for the project, which are on file with Federal Way Public Schools (FWPS). While not construction-level detail, the plans accurately represent the eventual size, location and configuration of the structure and are adequate for analysis and disclosure of probable environmental impacts. The Environmental Checklist is organized into three major sections. Section A of the Checklist provides background information concerning the FWPS proposal (e.g., purpose, applicant, contact person, project description, location, etc.). Section B contains the analysis of probable environmental impacts that could result from implementation of the proposal, based on review of major environmental parameters. This section may also identify possible mitigation measures. Section C contains the signature of the person preparing the checklist, confirming the completeness of this Environmental Checklist.

Asbestos containing materials of greater than 1% were found in vinyl floor tile, and black mastic on concrete (under carpet), black speaker box coating, popcorn ceiling, hard mudded fittings, marble crete, silver paint associated with built up roofing and presumed to be in the fire door, cement asbestos pipe and in the electric insulator board panels in the boiler room. Other materials found includes lead in 10/15 samples collected, and mercury and PCB-containing components in the fluorescent light tubes 1) Describe any known or possible contamination at the site from present or past uses. Washington Department of Ecology “What’s in My Neighborhood” database identifies a Chevron site located approximately 0.5 miles northwest of the Olympic View Elementary site that is identified as containing benzene, lead, diesel, gasoline and other petroleum as contaminants; however it has a cleanup status of “no further action” required. SEPA Environmental checklist (WAC 197-11-960) April 2021 Page 15 of 34 Federal Way Public Schools 33330 8th Avenue South Federal Way, WA 98003 (253) 945-2000 The Ecology database also identifies the project site as being located within the Asarco Tacoma Smelter Plume area and the Department of Ecology Tacoma Smelter Plume map identifies the site as having 20 ppm – 40 ppm of arsenic levels. The Arsenic and Lead Soil Sampling Report prepared by PBS indicated an isolated area of elevated arsenic concentrations. Following a work plan and Voluntary Cleanup Program application to Ecology, a supplemental sampling was completed in the area. 2) Describe existing hazardous chemicals/conditions that might affect project development and design. This includes underground hazardous liquid and gas transmission pipelines located within the project area and in the vicinity. The National Pipeline Public Mapping System did not identify any hazardous liquid or gas transmission pipelines with the project area or the vicinity of the site. 3) Describe any toxic or hazardous chemicals that might be stored, used, or produced during the project's development or construction, or at any time during the operating life of the project. The proposal does not involve the storage or use of toxic or hazardous chemicals. 4) Describe special emergency services that might be required. No additional special emergency services will be required other than those normally provided such as police, emergency medical, and fire protection. 5) Proposed measures to reduce or control environmental health hazards, if any: Soil remediation is in process for an isolated area containing elevated levels of arsenic. A workplan and Voluntary Cleanup Application was submitted to the Department of Ecology, and supplemental sampling was recently completed by PBS Environmental. A request has been submitted to the Washington State Department of Ecology for a No Further Action likely opinion letter. Should the Department of Ecology issue the opinion that cleanup activities at the site are not sufficient, additional remediation will be completed until the No Further Action Letter is provided. The removal and disposal of hazardous building materials will occur following the required local, state and federal regulations and the recommendations provided in the Hazardous Materials Survey.
