Templates for Project Level Analysis Using MOVES, CAL3QHC/R and AERMOD

The research objective of National Cooperative Highway Research Program (NCHRP) Project 25-25 Task 71 was to develop a project-level analysis air quality technical report template. The Project-Level Analysis Report Template is intended to reduce the time and cost necessary to complete air quality studies for proposed transportation projects, to improve the consistency and quality of these studies, and to assist the transportation agencies in meeting new modeling and documentation requirements. The process for developing the preliminary Project-Level Analysis Template began with a review of recent air quality technical reports/conformity determinations to inform the development and organization of the template. Existing templates and state-level air quality analysis guidance documents were reviewed and state departments of transportation (DOTs) were contacted for information. The preliminary Project-Level Analysis Template was designed to address transportation conformity and National Environmental Policy Act (NEPA) requirements. The focus for the development of the Project-Level Analysis Template was on: 1) particulate matter hot-spot analysis (PM2.5 and PM10) with MOVES2010 and AERMOD or CAL3QHCR and 2) carbon monoxide hot-spot analysis with MOVES2010 and CAL3QHC (screening or CAL3QHCR (refined). The Project-Level Analysis Template was also designed to briefly address the topics of road dust and construction air quality impacts, Mobile Source Air Toxics (MSATs) and indirect effects and cumulative impacts to air quality. The preliminary Project-Level Analysis Template provides suggested language, guidelines and organization for air quality technical reports prepared to comply with the transportation conformity rules and guidance, as well as the NEPA. At the time of this publication, it is the authors understanding that the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation's Federal Highway Administration (FHWA) are reviewing the templates developed as part of this project for future use. To further assist practitioners in understanding how to tailor the preliminary Project-Level Analysis Template to the needs of their specific projects, three example reports for hypothetical transportation projects were prepared using the Project-Level Analysis Template. The example projects include a range of common transportation improvements, such as new interchanges, park-and-ride lots, bus terminals and intersection improvements. Based on the experience preparing the preliminary Project-Level Analysis Template and example reports, the conclusions section of this final report presents recommendations on future research opportunities to further reduce the time and cost of transportation project air quality studies, including the need for agencies to work together to update the template as models, guidance, and regulation change over time.
