Construction is expected to last 140 days.The EPA's 1999 final report on Estimating Particulate Emissions from Construction Operations identifies several methods for determining emissions(EPA 1999).Given the knowledge of the LCC, a Level 2 assessment to calculate emissions was used. The total amount of earth moved (248,888 cubic yards), Project Area (20 acres) and duration (140 days) are all known. Therefore, the following PM10 emission factors were applied: 0.011 ton/acre/month plus 0.059 ton/1,000 cy. It was assumed that only on-site cut and fill is performed. Given the 85 percent control and a 10 percent PM2.5/PM10 ratio as provided by EPA AP-42,Section 13.2,fugitive construction particulate emissions were calculated. Table 2.2-12 illustrates that the total emissions associated from the LCC are quite low and would have minimal impact on the surrounding area.
