I Draft Supplemental Environmental Impact Report Page IV.D-17 Forward Inc. Landfill 2018 Revised Project Cumulative Impacts According to the SJVAPCD GAMAQI, a cumulative impact occurs when two or more individual effects, considered together, are considerable or would compound or increase other environmental impacts. Cumulative impacts can result from individually minor but collectively significant impacts,meaning that the project's incremental effects are considerable when viewed in connection with the effects of past, current, and probable future projects.Notably, any project that would individually have a significant air quality impact would also be considered to have a significant cumulative air quality impact. According to the SJVAPCD GAMAQI, cumulative impacts should be assessed for ozone,PM,o,CO and TAC. Greenhouse Gases The project would be considered to have a significant impact if the project would be in conflict with State plans, policies and regulations adopted for the purpose of reducing GHG emissions, such as AB 32, with the assumption that State plans, policies,and regulations, such as AB 32, will be successful in reducing GHG emissions and reducing the cumulative GHG emissions statewide by 2020 and beyond. It is important that the State has taken these measures,because no project individually could have a major impact(either positively or negatively)on the global concentration of GHG. Impacts and Mitigation Measures This impact section evaluates the activities described in the Project Description that could potentially result in impacts to air quality, odors, and climate change based on the conditions of the project area. The project would add 8.1 million cubic yards of landfill capacity versus the 32 million cubic yards in the 2013 project, and the projected landfill closure date would be 2036 versus 2039 for the 2013 project. From an air quality perspective,the additional 8.1 million cubic yards would result in an increase in fugitive emissions from the landfill surface and an increase in emissions from LFG control devices due to the increase in LFG collected. The project would also result in an increase above the current annual level of traffic-related trips, which would result in an increase in emissions associated with traffic-related trips. Two Project scenarios were evaluated.The first scenario assumes that all LFG in excess of what is currently permitted for destruction in an Ameresco LFG to energy (LFGTE) facility would be destroyed in existing and future flares. The second scenario assumes that all LFG in excess of the current actual quantity of LFG sent to the flares is destroyed in existing and future LFGTE 1 facilities. Impact D.1. Initial construction activities for the expansion area would generate short-term emissions of criteria pollutants,including suspended and inhalable particulate matter(PMJ and equipment exhaust emissions (Revises 2013 EIR Impact D.1.). The project would include two distinct types of construction phases: the relocation of the Littlejohn Creek and the construction of new landfill cells. For the purposes of quantifying construction emissions, it was assumed that the creek location would occur at the same time as the construction of a new landfill cell.This assumption is conservative and would result in the
