7.A. - Page 22 ATfACHMENT 1 Mitigation: Mitigation 8-2. In addition to the project-proposed sustainability measures described in chapter 3 (Project Description) of the Draft EIR, which include a Transportation Demand Management (TDM) program, implement the following measure: Minimize testing of the new generators to reduce ROG emissions. New generator emissions, as computed on an annual basis, shall be reduced by 30 percent or greater. This could be achieved in a number of ways: 1. Install fewer than the assumed 13 new generators; 2. Install generators with lower emissions (in this case, smaller generators); 3. Test new generators at lower running loads (the analysis assumed 100- percent load, so 50-percent load would reduce emissions); and/or 4. Reduce the number of annual testing hours. The applicant shall submit an analysis of the new generator emissions prior to installing more than five new generators at the project development site. Finding: Implementation of Mitigation 8-2 would reduce ROG emissions by 2.7 pounds per day, resulting in total ROG emissions of 53.1 pounds per day (below the BAAQMD significance threshold of 54 pounds per day), a less-than-significant impact. However, this mitigation measure would reduce PM,o emissions by a minimal amount, leaving PM,o emissions above the BAAQMD significance threshold and resulting in a significant unavoidable project and cumulative operational air quality impact. Facts in Support of Finding: In combination with the project-proposed TDM program, implementation of Mitigation 8-2 would reduce the project's operational ROG emissions to a less-than-significant level by minimizing generator testing. However, even with all feasible mitigation, operational PM,o emissions would exceed the BAAQMD threshold, due mainly to overall traffic generated by full buildout of the project, resulting in a significant unavoidable project and cumulative operational air quality impact. These facts are described and quantified in Draft EIR chapter 8 (Air Quality) on pages 8-1 through 8-28, Draft EIR appendix 21.4 (Supplemental Air Quality and Climate Change Information), and Final EIR appendix B (Supplemental Bay Area Air Quality Management District [BAAQMD] Information), which are hereby incorporated by reference. Impact: Impact 8-3: Community Risk and Hazard Impacts. Project development could expose attendees of the on-site child care center to significant levels of PMz.s. Significant impacts from the Tyco Thermal Controls Facility to attendees of the proposed child care facility are anticipated to be significant regardless of where the child care facility is located within the Precise Plan area.
