EIR: Appendix G. Air Quality Record of Non-Applicability • APPENDIX G. AIR QUALITY RECORD OF NON-APPLICABILITY 0 FOR THE RANCHO PALOS VERDES FEASIBILITY STUDY JUNE 2000 0 • CONFORMITY DETERMINATION FOR RANCHO PALOS VERDES FEASIBILITY STUDY The Clean Air Act (CAA), as amended in 1990, specifies in Section 176(a) that no department, agency, or instrumentality of the Federal Government shall engage, in, support in any way, or provide financial assistance for, license or permit, or approve, any activity which does not conform to an implementation plan after it has been approved or promulgated under Section 110 of the Act. "Conformity" is defined in Section 176(c) of the CAA as conformity to the State Implementation Plan's (SIPs) purpose of eliminating or reducing the severity and number of violations of the national Ambient Air Quality Standards (NAAQS) while achieving expeditious attainment of such standards. Air quality standards in the feasibility study area is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). In 1995, SCAQMD measured pollutant concentrations from all their monitoring stations within their jurisdiction. Pollutant concentrations exceeded federal and state standards for ozone, carbon monoxide, and particulate matter, and the state standard for sulfate. Standards for nitrogen dioxide, sulfur dioxide, and lead were not exceeded. Calculations of the emissions associated with initial constructions and future operations and imaintenance activities were performed using guidance f om SCAQMD's 1993 California Environmental Quality Act (CEQA) Air Quality handbook, and following federal Applicability criteria for non-attainment areas. The analysis in this Appendix demonstrates that the activities associated with this project are below de minimis levels prescribed in 40 CFR 93.153(b), and is, therefore, exempt from demonstrating conformity to State or Federal Implementation Plans. 11 G-1 EMISSION CALCULATIONS Construction activities associated with the construction of the dike for the Palos Verdes Feasibility Study is expected to take 1.5 years. Operations and Maintenance activities are expected to take one year. The emissions calculations in this Appendix uses the equipment lists and hours of use identified in the Cost Engineering Appendix(Volume II) and is performed using guidance from SCAQMD's 1993 California Environmental Quality Act (CEQA) Air Quality handbook(SCAQMD 1993).
