Draft Supplemental Environmental Impact Report Page IV.E-17 <br /> Forward Inc. Landfill 2018 Expansion Project <br /> emission sources associated with the operation of the project such as flare and/or LFG engines, <br /> DPM emissions from increased truck trips, and fugitive LFG emissions. <br /> The incremental carcinogenic risk(increase in cancer risk from the Current Actual to the Project <br /> scenario Landfill Gas Flare)is estimated to be 4 cancer occurrences per million persons at the <br /> nearest occupied receptor. This value is below the threshold of 20 cancers per million and thus, <br /> the impact would be less than significant. <br /> This analysis is based on conservative(overestimated)assumptions, and can be considered a <br /> worst—case analysis. The maximum incremental cancer risk is relatively small compared with <br /> the overall lifetime cancer incidence of 200,000 to 250,000 per million in the United States. <br /> The OEHHA has established a significance threshold for non—cancer health risk based on <br /> concentrations that would result in a Hazard Index (HI)greater than 1.0. Based on the <br /> modeling,the non—cancer health risks would be well below the Hazard Index of 1.0 at all <br /> receptors. The maximum non—cancer acute hazard risk would be an HI of 0.0117. The <br /> maximum non—cancer chronic hazard risk would be an HI of 0.00016. The increased non-cancer <br /> acute and chronic hazard risk from the Project (increase in hazard risk from the Current Actual <br /> to the Project scenario Landfill Gas Flare)would be less than these maximum Project values. <br /> Maximum non-cancer hazard risk values (acute and chronic)are below the threshold of 1.0 and <br /> thus, the impact would be less than significant. <br /> Implementation of the measures identified in Mitigation Measure D.2a. in this EIR(See Air <br /> Quality Section)would reduce emissions and further reduce both cancer and non—cancer health <br /> risks near the project area. <br />
