Rants, Mayor Department of Community Development Steve Lancaster, Director MEMORANDUM To: Michael Jenkins, Acting Planning Manager From: Vernon Umetsu, Associate Planner Date: July 28, 1999 RE: File No. E99-0014 (SEPA Threshold Determination for Boeing Debris Removal) Project File No. E99-0014 Applicant: The Boeing Company Project Location: 8123 East Marginal Way South (Boeing Plant 2, Building 2-41). The construction site is located beneath the building's southwest corner, in the intertidal area that it overhangs. Project Description: The applicant proposes to remove 40 cubic yards of contaminated soil in conformance with the Elliott Bay/Duwamish Consent Order issued by the EPA to Boeing, and pursuant to Federal contaminated site clean-up provisions (Ex. B, Pg. 1). Contaminated soil and associated water will be temporarily held on site while drying. Soils and solid materials will then be transported to a hazardous waste landfill. Decanted water from the contaminated soil and ponded water in the excavation will be vacuumed and stored in 'containers for testing. Disposal shall be either into the sewer system with an industrial waste discharge permit or to a hazardous waste disposal facility. The construction would be no greater than 50 ft. by 50 ft., as needed to deploy equipment to vacuum excavate a by 17 foot by 20 foot by three foot deep hole for contaminated soil removal. Construction site access would be from above, through a hole cut into the building floor. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • (206) 431-3670 • Fax (206) 431-3665 SEPA Threshold Determination St eport E99-0014: Boeing Building 2-41 Debris Removal • Page 2 Comments to SEPA Checklist: A.10 Government approvals and permits required: Responses in this section are replaced by the table below: Required Permit Agency with Jurisdiction State Environmental Policy Act threshold determination.

King County Shoreline Master Program - P.1 GOAL: Perserve or Develop shorelines, adjacent uplands and adjacent water areas in a manner that assures a balance of shoreline uses with minimal adverse effect on the quality of life, water and environment. P.2 OBJECTIVE 3. B. COMPREHENSIVE PLAN POLICIES APPLICABLE TO PROJECT: (List the Comprehensive Plan sections, goals and/or policies, including page numbers, which apply.) Tukwila Comprehensive Plan - Shoreline Goal 5.10. p. 65 Policy 5.10.1 p. 65 V. SHORELINES DESIGN POLICIES All projects in the Shoreline Zone must be consistent with Tukwila's Comprehensive Plan and Shoreline Master Program policies (or King County's Shoreline Master Program if project located north of the 42nd Avenue bridge). In addition, all structures requiring a building permit (except single family development of 4 or fewer Tots) located in the Shoreline Zone must undergo design review with the Tukwila Board of Architectural Review (BAR). The BAR's decision is based on design guidelines contained in the Zoning Code (TMC 18.60.050) and the Tukwila Comprehensive Plan (see DESIGN REVIEW APPLICATION). The SHORELINE MASTER PROGRAM POLICIES and Comprehensive Plan's SHORELINE DESIGN POLICIES are summarized below. Note that more than one category may apply. In some cases, the goal for the use or area is noted to provide context for the design policies. NOTE: a) If your project requires a building permit you must meet additional criteria in DESIGN REVIEW APPLICATION. b) If your project requires a variance, you must meet additional criteria in VARIANCE PERMIT APPLICATION. c) If your project requires a conditional use permit, you must meet additional criteria in CONDITIONAL USE PERMIT APPLICATION. TUKWILA SHORELINE MASTER PROGRAM POLICIES (King County shoreline policies follow) A. ECONOMIC DEVELOPMENT ELEMENT 1. Commercial/industrial development along the shorelines should not favor outside interests at the expense of the local population. 2.

If so, generally describe. During sediment removal, the following appropriate technological measures will be taken to minimize the potential of sediment re-entering the waterway: • The use of vacuum -truck to remove the sediment • The installation of a silt fence and absorbent booms • The use of pumps to remove excess water These methods are described below. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: During sediment removal operations, sump pumps will be used to remove any excess water in the area. This water will be stored in temporary water storage tanks. Also, an absorbent pad boom will be placed on flat areas surrounding the excavation limits and a silt curtain will be installed around the excavation area, keyed into the sediment, and fixed to the pilings. These measures will reduce, to the greatest extent possible, the potential of sediment entering the water during sediment removal; therefore, decreasing the chance of increased turbidity. If more than one day is required to remove the sediment, the affected area will be covered with a geotextile fabric and weighted down with equally spaced sandbags, bricks, or other equivalent weights. These weights will be spaced at a maximum distance of 3 ft. Until the area is backfilled, geotextile will be placed each day before the removal area. becomes covered with water. 4. Plants a. Check or circle types of vegetation found on the site: N/A deciduous tree: alder, maple, aspen, other SEPA Checklist 2-41 Debris Clean-up 7 c:user\aaricks\sepa\2-41 cleanup checklist 03/23/99 • SEPA CHECKLIST • evergreen tree: fir, cedar, pine, other Shrubs Grass Pasture crop or grain wet soil plants: cattails, buttercup, bulrush, skunk cabbage, other water plants: water lily, eelgrass, milfoil, other other types of vegetation b.

List any threatened or endangered species known to be on or near the site Species proposed for listing, known to be near the site, are Chinook salmon (Oncorhynchus tshawytscha) and bull trout (Saivelinus confluentus). c. Is the site part of a migration route? If so, explain. Yes, salmonids migrate near this area during both their upstream migrations and outmigrations. Adult Chinook salmon migrate upstream from mid-June through the beginning of November, but they most likely migrate by this site from mid-June through mid-October. Juvenile SEPA Checklist 2-41 Debris Clean-up 8 c:user\aaricks\sepa\2-41 cleanup checklist 03/23/99 • SEPA CHECKLIST • outmigration takes place from the beginning of April to the beginning of August. Bull trout do not spawn in the Green/Duwamish River; therefore, they do not migrate near the site. However, some adult bull trout have been seen in the lower reaches of the Duwamish River up to Soos Creek (Cropp, T., WDFW, pers. comm. 1998). d. Proposed measures to preserve or enhance wildlife, if any: The proposed project in itself will help improve wildlife habitat by removing sediment with elevated levels of lead. Measures taken during the proposed project to preserve wildlife will include the use of an absorbent pad boom placed on flat areas surrounding the excavation limits and a silt curtain installed around the excavation area, keyed into the sediment, and fixed to the pilings. These measures will reduce, to the greatest extent possible, the potential of sediment entering the water during sediment removal; therefore, decreasing the chance of increasing turbidity. Additionally, work will not take place during March 15 and June 14, when juvenile salmonids would be present. 6. Energy and Natural Resources a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. None b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. No c.

This action targets the site of a former pile of debris located beneath the pile -supported portion of Building 2-41, which is cantilevered over the Duwamish River. This action will precede the proposed remedy for the entire Duwamish Sediment Other Area (DSOA) which includes dredging 3 ft of sediment within the DSOA and backfilling with clean cap material. The proposed remedy for the DSOA is detailed in the Focused Corrective Measures Study that is currently under review by the US Environmental Protection Agency (EPA). This IM Work Plan has been prepared to be consistent with the requirements of the Administrative Order on Consent (Order) issued by EPA to Boeing under the authority of Section 3008(h) of the Resource Conservation and Recovery Act (RCRA) of 1976, as amended, 42 USC 6928(h). This Order [RCRA Docket No 1092-01-22-3008)h)] became effective on January 18, 1994. 1.1 RATIONALE This proposed action targets an area of elevated lead concentrations found under Plant 2 Building 2-41 in the Duwamish Sediment Other Area (DSOA). Although the elevated lead concentrations do not present "an immediate threat to human health and the environment," Boeing is proposing this IM for the following reasons: • Removal of the "hot spot" source area will reduce potential lead migration. • The IM will reduce potential exposure prior to implementation of the proposed remedy for the DSOA. • The action will be consistent with the proposed remedy for the DSOA.

Responsibilities include project oversight, permitting, integration of the interim measure with the proposed remedy for the February 1. 1999 00301\002\105\im\imworkplanrev4 _r.doc:cjw page 2 • • Interim Measure Work Plan Pentec DSOA, and other miscellaneous support items associated with planning and performance of the work. Pentec will be the design and construction engineer and will have responsibility for work planning and design, coordinating efforts of the interim measure contractor, managing and overseeing interim measure construction, documenting construction progress and compliance with quality assurance requirements, and preparation of a completion report. 1.3.3 Interim Measure Construction Subcontractor The IM construction subcontractor will be responsible for site ,preparation, excavation and material handling, deployment of runoff control measures, procurement and placement of backfill, moisture reduction of recovered sediment, worker health and safety, and personnel and equipment decontamination. The IM construction subcontractor will report directly to the on-site construction engineer. 2.0 DESCRIPTION OF PROJECT AREA In the summer of 1998, Boeing located an isolated pile of debris under the pile -supported portion of Building 2-41 that is cantilevered over the Duwamish River (Figures 1 and 2). Boeing removed the debris in August 1998 in order to minimize impacts to design and implementation of the proposed remedy for the DSOA. The debris that was removed from the site included chunks of metal, broken timbers, and battery cases. Because there were battery cases in the debris, Boeing proceeded to evaluate the potential for elevated lead concentrations in the sediment that was left in place and conducted a focused sediment sampling program in the area. Ten locations in the vicinity of the former debris pile were sampled (Figure 2). At these locations, 3 -ft deep composite sediment cores were collected and analyzed for total and leachable (via Toxicity Characteristic Leachate Procedure [TCLP)) metals. A 3 -ft depth is consistent with the remedial action proposed for the entire DSOA. Results of these analyses are provided in Appendix Tables 2 and 3. Elevated concentrations of total and leachable lead were found at several of the sampling locations (Figure 3). These results indicate lead concentrations in sediment that warrant action within an approximately rectangular area having horizontal dimensions of roughly 17 ft by 20 ft (Figure 3).
