I apologize for any confusion caused by the separate activities of Buyer and Seller at the subject property. We are separate businesses with very different reasons for site activities. PACCAR's (Seller) involvement is limited to investigation and remediation of the site under the Voluntary Clean -up Program (VCP) with the Department of Ecology. Washington Holdings (Buyer) initial work includes demolition of several buildings at the site among other activities that they have discussed separately with you. As we discussed, PACCAR would like to proceed in an expeditious manner with removal of a very small volume (estimated at no more than 135 cubic yards) of impacted soil west of building "B ". PACCAR is not in a position nor do we believe it is appropriate to include this limited soil excavation in the Buyer's SEPA application that covers demolition of multiple buildings at the site. PACCAR has requested a Public Works Construction Permit for the proposed excavation west of Building B because of the small volume and quick approval was expected. Rapid approval is important to minimize the disruption to the future tenant. The proposed area for excavation is centrally located and would present logistical problems if the tenant were occupying the site. We thank you for your efforts and trust the City of Tukwila will understand the importance of expeditious approval of the requested permit for the small excavation west of building B. If you have any question or comments please call at (425) 468 —7928, or contact me by email at alex.buccilli(a�paccar.com.

Location of Proposal: 8801 East Marginal Way South Lead Agency: City of Tukwila File Number: E03 -027 Description of the original proposal: The scope of the original proposal was to install an air sparging and soil vapor extraction system for groundwater remediation purposes. The scope of the work included sawcutting and removal of approximately 2,300 square feet of asphalt and concrete pavement, excavation of approximately 260 cubic yards of material from the sawcut area, backfilling of the excavation following installation of the air sparging and soil vapor extraction systems and restoration of the asphalt and concrete surface. The purpose of this system is to mitigate the migration of volatile organic compounds present in the site groundwater -and reduceithe potential of these compounds to discharge to the Duwamish Waterway located adjacent to the western property boundary. This project is being performed under the Ecology's Voluntary Cleanup Program. An addendum was adopted on March 30, 2004, for removal and disposal of approximately 500 cubic yards of the contaminated soil (with petroleum hydrocarbons), which was discovered in the vicinity of the trench during construction of the trench for the installation of the air sparging and soil vapor extraction system. The additional volume of soil to be removed was about 40 feet long, 50 feet wide and 7 feet deep. The second addendum was adopted on June 21, 2004, for removal of additional contaminated soil at a different location on the subject property. The additional work included saw cutting and demolition of existing pavement, excavation and disposal of soil with petroleum hydrocarbons, backfilling/compaction, and pavement restoration over an area measuring 300 feet long by 15 feet wide. The planned depth of excavation was 8 feet deep and it varied depending on the location of the impacted soil. The estimated volume of excavation was 1,350 cubic yards. Impacted soil was legally transported and disposed at Waste Managements Colombia Ridge, Oregon landfill.

Property at 8801 East Marginal Way South Dear Ms. Dhaliwal, • On behalf of our client PACCAR, Inc., Glacier Environmental Services, Inc. requests amendment to the Planned Action Determination issued for their 8801 East Marginal Way site. The original proposal was submitted by Kennedy /Jenks Consultants for installation of an air sparging and soil vapor extraction system. The original Planned Action Determination was issued on January 2, 2004. On March 30, 2004, an addendum was adopted for the excavation and legal off-site disposal of petroleum contaminated soil encountered during construction of the original proposal. This request is submitted to facilitate issuance of a Land Altering Permit to perform remedial excavation at different location on the property. The project will be completed under Ecology's Voluntary Cleanup Program. The approximate location of this proposed excavation is shown on attached Figure 1. This proposal includes saw cutting and demolition of existing pavement, excavation and disposal of soil with petroleum hydrocarbons, backfill /compaction, and pavement restoration over an area measuring 300 feet long by 15 feet wide. The planned depth of excavation is 8 feet deep but may vary depending on the location of impacted soil. The estimated in -place volume of excavation is 1,350 cubic yards. Impacted soil will be legally transported and disposed at Waste Managements Colombia Ridge, Oregon landfill.

For estimating purposes lets assume that we may remove up to.500 cubic yards of soil in an area extending approximately 25 feet both east and west of the trench along the proposed 40 foot length to a depth of 7 feet. A revised map of the potential excavation area is attached. Please note that the excavation will only extend as far as necessary to remove impacted soil which may ultimately be very limited in extent. Also please note that my main interest is to start the excavation work quickly to resume construction of the Air Sparging /Soil Vapor Extraction System. If removal of 200 cubic yards of soil is more likely to be approved than 500 then please follow -up with the original request. We believe that this removal action is consistent with the requirements of WAC 173 -27 -100. Please advise as to what further steps we need to take or approvals to seek.

Alex Original Message From: Alex Buccilli Sent: Friday, March 26, 2004 1:11 PM To: 'mdhaliwal @ci.tukwila.wa.us' Cc: Carole Robbins Subject: Shoreline Permit #L03 -067 Request for conducting soil excavation under the existing shoreline permit Importance: High Pursuant to our conversation, please find attached a map showing the planned excavation of potentially impacted soil at the PACCAR Seattle facility located in 8801 East Marginal Way, Tukwila. The impacted soil was discovered during the excavation of a trench to accommodate an Air Sparging /Soil Vapor Extraction System (AS /SVE) on the west side of the facility. This project is being conducted under a Voluntary Cleanup Program with the WA Department of Ecology. The City of Tukwila already granted the Shoreline Permit #L03 -067 for the AS /SVE construction. The Shoreline permit was necessary since the location of the AS /SVE system is within 200 feet from the Duwamish River. As discussed, soil potentially impacted with petroleum hydrocarbons appears to extend for 30 linear feet along the trench and up to 6 feet deep. PACCAR wishes to remove the soil, properly dispose of it and backfill the excavation prior to continuing with the AS /SVE installation. It is not possible at this time to predict the lateral extent of the impacted soil and the quantity of soil that will be necessary to remove. PACCAR is planning to extend the soil removal for at least 10 feet on both sides of the system. This is necessary to avoid any future disturbance and damage to the AS /SVE system. er the existing shoreline 2 MinNe Dhaliwal - RE: Shoreline Permit #L' .7 - Request for conducting soil exca vat In conclusion we are requesting authorization to remove and properly dispose soil under the current Shoreline permit for the AS /SVE project. The volume of soil to be removed will be a minimum of 40 feet long, 20 feet wide and 7 feet deep. Allowing for 20% additional soil, this amounts to a range of between 200 to 240 cubic yards of soil. The proposed excavation area is showed in the attached drawing. The actual soil excavation may have a different shape from what is indicated in the drawing depending upon the actual location of impacted soil. We believe the proposed work'is in conformance with the existing shoreline permit and will have a beneficial environmental impact. PACCAR wishes to proceed immediately with the soil removal in order to finalize the construction of the AS /SVE system and to meet the project schedule previously agreed with the Department of Ecology.

SUMMARY OF PROPOSED ACTION The project is to install an air sparging and soil vapor extraction system for groundwater remediation purposes. This project is being performed under the Ecology's Voluntary Cleanup Program. II. GENERAL INFORMATION Project Name: Groundwater remediation project at Kenworth site. Applicant: Ross Dunning (Kennedy /Jenks Consultants) for Paccar Inc. Location: 8801 East Marginal Way South Zoning and Comprehensive Plan Designation: MIC/H III. REVIEW PROCESS This proposal was identified as a potential Planned Action as it met the requirements listed under Tukwila Municipal Code (TMC) Section 21.04.152. As part of this Planned Action review process, the proposed project is analyzed to ensure that all impacts have been mitigated as part of 1998 EIS and also if the proposal is consistent with the Tukwila Comprehensive Plan. Tukwila's Manufacturing and Industrial Center (MIC) is an important regional center of industrial activity. Industrial development over the most of the sub -area was evaluated in multi -site environmental review. In 1992, a programmatic environmental impact statement (EIS) was prepared for the Duwamish Corridor master plan, a proposal to redevelop Boeing properties in the MIC over a 10 year period. In 1998, sub -area plan/EIS updates extended the previous analysis of the corridor's Boeing properties (about 650 acres) to the entire MIC sub -area (about 1,370 acres). As part of this Planned Action review for the current proposal, the impacts of the current proposal are compared to 1998 Integrated GMA Implementation Plan and Final Environmental Impact Statement in order to ensure that all impacts have been mitigated. IV. BACKGROUND/PROPOSAL The project is to install an air sparging and soil vapor extraction system for groundwater remediation purposes. The purpose of this system is to mitigate the migration of volatile organic compounds present in site groundwater and reduce the potential of these compounds to discharge to the Duwamish Waterway located adjacent to the western property boundary. This project is being performed under the Ecology's Voluntary Cleanup Program. The scope of the work includes sawcutting and removal of approximately 2,300 square feet of 1 • • asphalt and concrete pavement, excavation of approximately 260 cubic yards of material from the sawcut area, backfilling of the excavation following installation of the air sparging and soil vapor extraction systems and restoration of the asphalt and concrete surface. - The project area is located within 200 feet of the Duwamish Waterway and a shoreline substantial development permit is being processed for the proposed project. V. CONSISTENCY WITH COMPREHENSIVE PLAN The City of Tukwila Comprehensive Plan identifies the area surrounding the subject site as a Manufacturing Industrial Center/Heavy. The proposed project meets the goals and policies listed in the Comprehensive Plan for MIC/H area. Specifically, the proposed project meets the following goals and policies: Goal 11.1: Support the existing industrial activities in the MIC and development of new industrial activity in order to maximize the employment and economic benefits to the people to Tukwila in the region, while minimizing impacts on residential neighborhoods. Policy 11.1.2.: Assist landowners in remediating site problems caused by contaminated soil. VI. REVIEW OF THE PLANNED ACTION CRITERIA CHECKLIST No change is proposed to the existing use of the site and the existing use is permitted in the MIC/H zone. Compliance with all local, state and federal laws will mitigate any impacts associated with this project. The proposal is consistent with the Tukwila's Comprehensive Plan. The project is not included in the list of projects that are exempt from being considered planned action. VII. CONCLUSION The current proposal for groundwater remediation is consistent with the City's Comprehensive Plan. It is also determined that all impacts associated with the current proposal have been mitigated pursuant to the environmental impact statement or will be mitigated by compliance with local, State and Federal Laws.

SEPA Planned Action and Shoreline Permit Application for the air sparging and soil vapor extraction (AS /SVE) system installation project proposed at the PACCAR Seattle facility located at 8801 East Marginal Way South in Tukwila, Washington. This letter provides a brief description of the project scope of work and work area, a discussion of the regulatory framework of the project, and description of the erosion and sedimentation control plan to be implemented for the project. Please refer to the Permit Application and submitted drawings for additional information. Background and Purpose The purpose of this project is to install an AS /SVE system for groundwater remediation purposes. The purpose of the AS /SVE system is to mitigate the migration of volatile organic compounds (VOCs) present in site groundwater and reduce the potential of these compounds to discharge to the Duwamish Waterway located adjacent to the western property boundary. Additional information regarding site groundwater conditions is available upon request. The scope of work will include sawcutting and removal of approximately 2,300 square feet of asphalt and concrete pavement, excavation of approximately 260 cubic yards of material from the sawcut area, backfilling of the excavation following installation of the AS and SVE systems, and restoration of the asphalt and concrete surface. Please refer to the project plans for the approximate dimensions and locations of the excavation area and for the specifics of the AS /SVE system design. Based on our discussions with the City of Tukwila on 14 August 2003, we understand that a SEPA Planned Action and Shoreline Permit are required for this project. The SEPA Planned Action and Shoreline Permit Application and appropriate civil and shoreline plans are included with this letter. Kennedy /Jenks Consultants Mr. Brandon Miles City of Tukwila 6 November 2003 Page 2 Regulatory Framework The City of Tukwila requested that we include documentation of Washington State Department of Ecology (Ecology) approval of this project with the permit application. This project is being performed under the Ecology's Voluntary Cleanup Program (VCP) (VCP Site ID# NW0960). The case officer assigned to the site is Ms. Maura O'Brien with Ecology's Northwest Regional Office (please route any correspondence to Ms. O'Brien through Kennedy /Jenks Consultants). Kennedy /Jenks Consultants has submitted a Work Plan for the project to Ecology for their review and comment. Project activities will begin following approval of the final Work Plan by Ecology. A copy of the final,Work Plan can be provided to the City upon request. Work Area Description The work area for this project is located on the western portion of the PACCAR Seattle site. The entire site is enclosed by chain -link fence, and security personnel are present at all times. The site is not accessible to the general public. The ground surface in the work area is paved with asphalt or concrete, depending upon the location, and is generally flat. The surface is gently contoured in some locations to facilitate stormwater runoff to catch basins. No modification of the existing surface topography is planned for this project. The AS /SVE excavation area is located within 200 feet of the Duwamish Waterway, although we do not anticipate that excavation activities will extend within 50 feet of the waterway. No work will be performed within or on the margin of the waterway. The boundary between the site and the Duwamish Waterway consists of a vertical sheet - piling bulkhead on the northern two- thirds of the site, and a steep rock embankment on the southern one third of the site. A chain -link fence is present along the entire length of the waterway. The shoreline will not be modified in any way as part of this project. Potential sediment runoff during construction activities will be mitigated through the implementation of erosion and sedimentation control best management practices as defined in the Temporary Erosion and Sedimentation Control Plan developed for the project (see below). Temporary Erosion and Sedimentation Control Plan A Temporary Erosion and Sedimentation Control Plan has been prepared for this project and is . included in the project plans. The general content of the Temporary Erosion and Sedimentation Control Plan is summarized below. The primary potential sediment runoff pathway from the site is through catch basins located in the work area, which discharge to the Duwamish Waterway. Direct runoff (not through catch basins) of sediment to offsite locations is not anticipated, as runoff water in the work area is w:120031036025.00111 rwd 21. d oc Kennedy /Jenks Consultants Mr. Brandon Miles City of Tukwila 6 November 2003 Page 3 directed toward catch basins: Catch basins in proximity to the work area will be fitted with catch basin inserts and surrounded by hay bales to trap sediment that may be entrained in surface water runoff. The catch basin inserts and hay bales will be inspected daily, and cleaned or replaced as necessary. Loose sediment will be removed from the asphalt/concrete surface in the work area (and onsite haul routes) as necessary. In addition, if excavated soil or imported materials are stockpiled onsite, the stockpiles will be contained within a bermed enclosure underlain and covered with impermeable plastic sheeting to minimize the potential for erosion and runoff to catch basins.

Please circle appropriate response. 0 Continue to Question 3 -0 YES - Continue to Question 2 -1 3 -0 Will the project require work, during any time of the project, below the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers or in wetlands? Ordinary high water mark is the mark that is found by examining the bed and banks of a stream and ascertaining where the presence and action of waters are so common and usual as to distinctly mark the soil from that of the abutting upland, in respect to vegetation (see TMC Chapter 18.06, Page 18 -15). P. . se circle appropriate response. NO - ontinue to Question 4-0 YES - Continue to Question 3 -1 4 -0 Will the project result in the processing or handling, storage, or treatment of hazardous substances? This does not include the proper use of fuel stored in a vehicle's fuel tank. Hazardous substances are any liquid, solid, gas, or sludge, including any material, substance, product, commodity, or waste, regardless of quantity, that exhibits the characteristics or criteria of hazardous waste as defined by Washington Administrative Code 173 -303 (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -11). This includes fuel or other chemicals stored on -site during construction. Please circle appropriate response.

This includes any projects that will require grading on any slope leading to a river or stream, but will not require work bebw the ordinary high water mark. Work below the ordinary high water mark is covered in Part C. Please circle appropriate response. ontinue to Question 1 -2 YES - Continue to Question 1 -2 1 -2 Could the construction, operation, or maintenance of the project result in sediment transport off site or increased rates of erosion and/or sedimentation in watercourses, the Green/Duwamish rivers, or the Black River? Most projects that involve grading have the potential to result in increased erosion and/or sedimentation as a result of disturbances to the soil or earth. If your project involves grading and you have not prepared a Temporary Erosion and Sedimentation Control Plan specifically designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please circle appropriate response. NO - Continue to Question 1 -3 Continue to Question 1 -3 1 -3 Will the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -12). Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development. Please circle appropriate response. NO - Continue to Question 2 -0 Continue to Question 1 -4 1 -4 Will your project generate stormwater from the creation of impervious surfaces that will not be infiltrated on site? For the purpose of this analysis, infiltration includes the use of a stormwater treatment and management system intended to contain all stormwater on site by allowing it to seep into pervious surface or through other means to be introduced into the ground. If your project involves the construction of impervious surface and does not include the design of a stormwater management system specifically designed to infiltrate stormwater, answer Yes to this question. Please circle appropriate response. (NO - ontinue to Question 2 -0 YES - Continue to Question 2 -0 Part C: Please review each question below for projects that include clearing.
