TASK 2 - PHASE 1 ENVIRONMENTAL SITE ASSESSMENT Kimley-Horn will prepare a Phase I Environmental Site Assessment (ESA) in accordance with the due diligence procedures and methodology presented in the American Society for Testing & Materials (ASTM) E 1527-05. The purpose of the Phase I ESA is to provide the following: • An identification of Recognized Environmental Conditions (RECs) as defined in ASTM E 3527-05,1.1.1 • An opinion of the impacts on the property resulting from conditions identified during the investigation, by a qualified Environmental Professional (EP) (ASTM E 1527-05,12.6) • An opinion, by a qualified EP, on the need for additional investigations (ASTM E 1527-05, 12.6.1) • A statement consistent with ASTM E 1527-05, 12.13, on the qualifications of the EP and the suitability of the Phase I ESA to meet the requirements of The All Appropriate Inquiry Rule, CFR 40 312. This Phase I ESA will also provide comments on non-scope considerations defined under ASTMT 1527-05,13. The assessment will reflect the general national standard of practice and the local customary practice as understood by Kimley-Horn. The EP will use ASTM 1527-05 along with our judgment and experience when reviewing results of the assessment and in identifying findings and RECs (ASTM E 1527-05, 1.6). Kimley-Horn's scope of services for conducting the Phase I ESA consists of the sub-tasks set forth below.
