ZMassociates has been tasked to perform one of the first, if not the first, U.S. EPA 2012 required Conformity Analysis of project PM10 & PM2.5 emissions for a planned California highway project in the High Desert Corridor.
This project will require developing an extensive mobile and stationary source emission inventory over the entire 60+ mile length of the project. The inventory will be based on a detailed traffic study, calculating mobile onroad emissions using the EMFAC model, obtaining local air district emission data for nearby stationary sources, obtaining data from two local met stations, using EPA’s recent guidance on transportation conformity analysis, and collaborating with various state, local, and federal agencies.
Once the inventory is developed for several possible project alignment options, the AERMOD model will be set up and ran for the various possible project options, including the no-build option used as background.
A conformity analysis will compare the background estimated emission levels for selected receptors against the emissions for the various project alignment scenarios.
ZMassociates is excited with this project opportunity, and to be one of the first to perform this analysis for transportation projects.
