To reflect implementation of proposed dust control <br />strategies, the following was assumed in CalEEMod: <br />• Water exposed area three times per day (61% reduction in PM10 and PM2.5). <br />• Limit vehicle travel on unpaved roads to 15 miles per hour. <br />Operation <br />Emissions from the operational phase of the Project were estimated using CalEEMod Version 2016.3.2. Operational <br />year 2022 was assumed consistent with completion of Project construction. Although emissions reductions were <br />not quantified, the Project would incorporate the PDFs summarized above. <br />Area Sources <br />CalEEMod was used to estimate operational emissions from area sources, including emissions from consumer <br />product use, architectural coatings, and landscape maintenance equipment. Emissions associated with natural gas <br />usage in space heating and water heating were calculated in the building energy use module of CalEEMod, as <br />described in the following text. <br />Consumer products are chemically formulated products used by household and institutional consumers, including <br />detergents; cleaning compounds; polishes; floor finishes; cosmetics; personal care products; home, lawn, and <br />garden products; disinfectants; sanitizers; aerosol paints; and automotive specialty products. Other paint products, <br />furniture coatings, or architectural coatings are not considered consumer products (CAPCOA 2017). Consumer
