Confidential Utility Client
Project: Air Emissions and GHG Mitigation Implementation Support
ZMassociates performed complex detailed research for emission factors for a long list of onroad and offroad vehicles to update GHG and criteria pollutant emissions estimates for a large utility project in Southern California. This included large, medium, and small helicopters, construction vehicles, and updated emission factors for offroad engines being upgraded or retrofitted for the project. ZMassociates easily modeled the update to better reflect specifics of the project as planned, allowing for significant reduction in EIR/EIS calculated emissions. This detailed work provided documented, defensible, and accurate estimates of the project emissions, putting the client in a position to better negotiate project emission offsets and mitigation measures.
