Agency (EPA) Rule on All Appropriate Inquiry (AAI) with the resulting revisions to the ASTM E 1527-05 has been addressed. The AAI Rule expands the records review requirements by increasing the search distance beyond the former ASTM E 1527-00, incorporation mandatory searches for engineering and institutional controls, and mandatory review of local goverunent and Indian tribal records. URS will confirm that the historical sources and data gaps identified for the project site has been documented and their significance reported. URS will provide a letter summarizing the resLilts of the review. URS will provide our services for a sump sum included in the project budget that has been placed in an envelope and attached to this proposal. During the course of our Phase I ESA review, if URS determines that the previous Phase I ESA was inadequate, then we prepare a letter report that addresses the new U.S. EPA Rule on All Appropriate Inquiry with the resulting revisions to the .ASTM E 527-05 are addressed. An additional lump sum fee for this work has been included in the project budget. During the course of our Phase I ESA review and/or Phase supplemental report, URS will apprise the City of any findings that could indicate the need for further investigation of any hazardous conditions on the project site. URS understands that the current use for the project site is for used car sales and repair. Depending on the condition of the project site, URS will be able to provide recommendations on whether further investigation is necessary, including the preparation of a Phase II EAS. The cost of preparing a Phase 11 ESA would be based on a time -and -materials basis that has not been included in this scope of work or project budget. d. Noise Study The URS Noise and Vibration Group staff will assess the existing land uses on and surrounding the project site using the most recent land use mapping provided by the City for the proposed commercial project. This inforrnation will be verified by a windshield survey of the proposed location. Future proposed land uses in the vicinity of the project site will also be identified. This information is necessary to prepare an accurate noise assessment of the proposed project. URS also will conduct a long -teen (24-hour) and short -teen (10-15 minutes) ambient noise measurements to quantitatively assess existing noise levels. The purpose of these measurements is to determine existing noise exposure levels and provide a baseline for assessing changes in noise levels attributable to the proposed project. The project is expected to generate traffic which will increase the level of vehicles traveling on the roadways in the vicinity of the project site. The change in the projected noise exposure level due to the expected increase in traffic will be calculated, and any impacts to noise sensitive land uses in the project area associated with those noise level increases will be identified. 5
