Research for the AASHTO Committee on Environment and Sustainability. Task 104. Streamlining Carbon Monoxide Project-Level Air Quality Analyses with Programmatic Agreements

NCHRP 25-25 Task 78, “Programmatic Agreements for Project-Level Air Quality Analyses,” completed in 2015, successfully developed templates for a programmatic agreement (PA) and an associated technical support document (TSD) that were designed to be used by state DOTs to streamline project-level air quality (hot-spot) analyses for carbon monoxide (CO). The Task 78 study used MOVES2010b; which has since been replaced by EPA with MOVES2014a. FHWA announced that it is undertaking a streamlining effort by conducting CO project level analysis to reduce the analysis burden of State DOTs and project sponsors when assessing the air quality impacts in the project development process. Task 104 updated the Task 78 PA and TSD as needed (e.g., update the modeling to use current models and cover additional project configurations and/or types). This project includes piloting the updated templates with a state DOT, making revisions to the templates as needed (e.g., to update the modeling to use current models, cover additional project configurations and/or types, and then apply state-specific modeling inputs), and continuing through necessary approvals and execution with FHWA. Lessons learned through this initiative can inform and assist the subsequent implementation of the updated templates for state DOTs across the nation.
