ADaPT Engineering, Inc. 2.0 INTRODUCTION 2.1 Purpoae The purpose of the Phase I is to evaluate the proposed lease area and host parcel for indic�tions of recbgnized environmental conditions due to previous w ongoing, on-site and ofF-sRe activities or conditions. Where appliqble, the Phase I also strives to satlsfy one of the requfrements to qualify for the innocent purohaserAandowner defense to Comprehensive Environmental Response, Compensation and Liability Act, 42, U.S.C. 9601, et seq. (CERCLA) liability. The Washington Model Toxics Control Act (MTCA), Chapter 70.105D Revised Code of Washin�ton (RCW) has a similar provision for exemption from liability. The Phase I endeavors to provide "all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice in an effort to minimize Ilabiliq�' as stated in CERCLA and MTCA. 2.2 Special Tertns and Conditions Authorization to perfortn this Phase I was given via VoiceSVeam PCS purchase order number SEA0000003746 dated April 13, 2000. 2.3 Scope of Work The scope of work for this study consisted of gathering reasonably ascertainable infortnation in general accordance with the American Sociery for TesHng and Materials (ASTM) Standard Practice for Phase I Environmental Site Assessments (ASTM Practice E 1527-97). Speaflcally, this Phase I consisted of the following: . A reconnaissance to assess the host paroel, the proposed lease area, and the parcels immediately surrounding the host pa►cel for recognized environmental conditions. . A review of regulatory agency (U.S. Environmental Protection Agency, Washington State Department of Ecology, etc.) database lists, and individual site files, if neoessary, to eva�uate reported environmental concems near the host parcel. . A survey of available local geologic and topographic maps, as well as addftional information conceming public and private water sources in the projed vicinity. . A review of historical sources including available business directories, aerial photographs, maps, tax assessment records, and building/planning department records. The historical information was used to evaluate past and present land use at the host parcel and immediate surrounding area to document businesses, activities, or conditions that oould possibly compromise the environmental integrity of the host parcel and proposed lease area. . Preparation of a report documenGng the findings of the Phase I and our opinion of the possibility that contamination of the host parcel and proposed lease area may exist due to on-site or nearby off-site land use activities.
