Santa Ana Renaissance Specific Plan Proposal M, Phase 5: EIR Preparation (to be executed under separate contract) vehicles, and fugitive dust from soil disturbance. A peak day and peak quarter con. struction emissions inventory will be prepared for comparison to APCD significance thresholds based on a reasonable worst case scenario developed by the project team. Emission sources quantified will include heavy equipment exhaust, fugitive dust, worker vehicles and heavy-duty on -road trucks. Inventory preparation will utilize emission factors from Non -road Engine and Vehicle Emission Study (EPA, 1991) and Motor Vehicle Emissions Inventory (MVEI) model (California Air Resources Board [ARB), 1996). Long-term emissions include vehicle emissions associated with trips generated by the proposed project and combustion emissions generated by water and space heaters. Long-term emissions will be presented in units of pounds per day for com- parison to the significance thresholds developed by the AQMD. Additionally, the study will include an analysis of carbon monoxide emissions at five (5) pre -deter- mined intersections within the study area. Vehicle emissions will be estimated consistent with the Handbook, using City -specif- ic inputs with the URBEMIS2001 model and trip generation values provided in the traffic study to estimate project long-term air emissions. Consistent with the pro. gram -level of analysis, no intersection modeling is proposed. An analysis of consis. tency with the Air Quality Management Plan will be provided. An analysis of the cumulative impacts of surrounding development will be provided and include the preparation of an emissions inventory for all proposed and approved projects in the immediate area, based on a project list provided by the City. Mitigation measures will be provided for both construction and operation impacts. Construction -related measures will focus on the use of heavy equipment certified to meet the 1996 Federal non -road NOx standard and dust control. Operation -related measures may include transportation demand management strategies, such as bike lanes, transit facilities, electric car charging stations and carpool matching services. The Air Quality Technical Report will be included in the air quality section of the EIR. 5.2.1H NOISE Padre Associates, Inc. will prepare a noise impact analysis. The noise analysis report Will include a setting discussion, traffic noise modeling to determine impacts, and mitigation to address potential impacts. Padre will conduct noise monitoring at the project site and adjacent residential properties to determine ambient noise levels. Monitoring will be conducted using a precision integrating type 1 sound level meter (Larson -Davis DSP -80) to collect A -weighted Leq sound data. The General Plan Noise Element will be reviewed to determine the location of the projected future traffic noise contours in the project area. A setting discussion will be provided and include the results of the monitoring and data review, the type and relative location of adjacent noise -sensitive land uses, and applicable noise thresh. olds. Thresholds may include the City's Municipal Code, the City's General Plan Noise Element and State Noise Guidelines.
