5.1 AIR QUALITY the potential impacts of climate change within the state as well as strategies for minimizing those impacts. 5.1.7.3 Consistency with Local Requirements: SJVAPCD The SJVAPCD has been delegated responsibility for implementing local,state,and federal air quality regulations in the eight counties33 within the SJVAPCD. The project is subject to SJVAPCD regulations that apply to new sources of emissions,to the prohibitory regulations that specify emission standards for individual equipment categories, and to the requirements for evaluation of impacts from toxic air pollutants. The following sections include the evaluation of facility compliance with the applicable SJVAPCD requirements. Under the regulations that govern new sources of emissions,the project is required to secure a preconstruction Determination of Compliance from the SJVAPCD (Rule 2201),as well as demonstrate continued compliance with regulatory limits when the project becomes operational. The preconstruction review includes demonstrating that the project will use BACT and will provide any necessary emission offsets. Applicable BACT thresholds are shown in Table 5.1-43,along with anticipated potential emissions from each unit and criteria pollutant. SJVAPCD Rule 2201 requires BACT for each unit emitting CO,NO,VOC,SO, or PM10 (criteria pollutants) in excess of 2.0 pounds per highest day (with facility-wide CO emissions in excess of 200,000 pounds per year). The calculation of facility emissions was discussed in Section 5.1.3. TABLE 5.1-43 Best Available Control Technology Requirements Turbine/HRSG Auxiliary Boiler BACT Applicability Maximum Maximum Threshold Emissions BACT Emissions BACT Pollutant (lbs/day) (lbs/day) Required?

As shown in Table 5.1-43, BACT is required as follows: • Turbine/HRSG: NO,VOC,SO2, CO,and PM10 • Auxiliary boiler: NO,VOC,SO2, CO,and PM1o. In addition, since the cooling tower daily emissions of 10.8 lb/day exceed the 2 lb/day BACT threshold, BACT is also required for PM10 emissions from the cooling tower. 33 Including the portion of Kern County that is within the SJVAPCD boundaries. 5.1-66 SAC/371322/082410013(LEC_5.1_AIR_QUALITY.DOC)
