ENVIRONMENTAL IMPACT REPORTADDENDUM Bristol Street Widening Phase IIIB— Washington Avenue to I7 h Street 3.7 Greenhouse Gas Emissions This section corresponds with Section IV - Environmental Consequences and Mitigation Measures, Subsections H - Air Quality, and V - Construction Impacts of the 1990 FEIS /EIR. a.) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Greenhouse gas emissions (GHG) were not evaluated in the 1990 FEIS /EIR. Construction activities would consume fuel and result in the generation of GHG emissions. Construction of the Project is anticipated to occur over a one -year period. Construction- related GHG emissions would cease upon completion of the Project. Due to the length of construction activities, GHG emissions associated with construction activities are anticipated to be minimal. Because construction emissions are not substantial and would cease after completion of construction, GHG emissions would not be significant. Furthermore, the Project proposes intersection widening of Bristol Street at 17" Street and Washington Avenue, therefore only carbon dioxide (CO2) emissions from mobile- sources are evaluated. Similar to the other criteria pollutants, the highest emissions would occur between 0 to 10 miles per hour (mph) and 50 mph and above. Because the Project would improve traffic flow within the Project area, the Project would result in reduced CO2 emissions. Consequently, GHG emissions associated with the Project would be less than significant. Mitigation Measures No mitigation measures are required. b.) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions ofgreenhousegases? The proposed Project would not conflict with applicable plans, policy, or regulations adopted for the purpose of reducing the emissions of GHG. The proposed Project would result in improved traffic flow, reduced vehicle idling times, and congestion. Implementation of the proposed Project would not result in new impacts to GHG. Mitigation Measures No mitigation measures are required. 3.8 Hazards and Hazardous Materials This section corresponds with Section IV - Environmental Consequences and Mitigation Measures, Subsections V - Construction Impacts, X - Hazardous Materials, of the 1990 Final EIS/EIR. a.) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials?
