Mitigation Measure 4.3-1: Generation of Short-Term Construction-Related Emissions of Criteria Air Pollutants and Precursors. A. SJVAPCD has indicated that the project may be subject to Rule 9510,Indirect Source Review(SJVAPCD 2006d). It would appear that the WQCF expansion portion of the project would be exempt in accordance with Section 4.4.3 of the Rule,which exempts facilities that are subject to the New and Modified Source Rule. Construction of the collection system and outfall would result in emissions of NOx in excess of 2.0 tons per year,which is a baseline for applicability of the Rule. Therefore,the City of Manteca will ensure that the proposed project complies with the following, as required by law: ► Submit an Air Impact Assessment(AIA)application to SJVAPCD. The AIA application will be submitted on a form provided by the SJVAPCD and contain,but not limited to,the applicant's name and address, detailed project description, on-site emission reduction checklist,monitoring and reporting schedule, and an AIA. The AIA shall quantify construction NOx and PMIo emissions associated with the project. (PMIo emissions would be less than 2 tpy;therefore, it may be acceptable to limit the AIA analysis to NOx emissions.)This will include the estimated construction baseline emissions, and the mitigated emissions for each applicable pollutant for the development project, or each phase thereof, and shall quantify the off-site fee, if applicable. General mitigation requirements, as contained in the ISR rule, include the following: • Exhaust emissions for construction equipment greater than 50 horsepower used or associated with the project will be reduced by 20%of the total NOx and by 45%of the total PMIo exhaust emissions from the statewide average as estimated by ARB. • Consider using less polluting construction equipment,which can be achieved by utilizing add-on controls, cleaner fuels, or newer lower emitting equipment. • Additional strategies for reducing construction emissions may include,but are not limited to: ■ Providing commercial electric power to the project site in adequate capacity to avoid or minimize the use of portable electric generators and the equipment; ■ Substitution of electric-powered equipment for diesel engine driven equipment; and ■ Limiting the hours of operation of heavy duty equipment and/or the amount of equipment in use at any one time. ► The requirements listed above can be met through any combination of on-site, emission-reduction measures or off-site fees. The ISR rule provides a method of calculating fees to be paid to offset any NOx and PMIo emission reductions that would not be achieved by selection of construction equipment and fuels. B. The City of Manteca will ensure that the proposed project complies with SJVAPCD's Regulation VIII, "Fugitive Dust Prohibitions,"and that all applicable control measures, as required by law, are implemented during construction to reduce the generation of fugitive PMIo and PM2.5 emissions. Regulation VIII contains, but not limited to,the following required control measures. 1. Prewater site sufficient to limit visible dust emissions(VDE)to 20%opacity. 2. Phase work to reduce the amount of disturbed surface area at any one time. EDAW Manteca WQCF and Collection System Master Plans EIR Air Quality 4.3-26 City of Manteca
