Project Level Conformity
Project level conformity determinations require that the FHWA/FTA project must come from a conforming transportation plan/TIP or associated regional emissions analysis. In addition, in carbon monoxide and particulate matter nonattainment and maintenance areas, an analysis of localized emissions may be required for federally funded or approved projects. This analysis is called a "hot-spot" analysis.
- Screening Procedures for Project-Level Hotspot Analysis or (PDF , 244KB) (April 2004) - FHWA Resource Center paper that provides a summary of project-level CO screening procedures developed and adopted by transportation agencies throughout the nation, highlights several innovative practices, and offers recommendations for developing refined screening protocols.
- Multi-Pollutant Emissions Benefits of Transportation Strategies or (PDF, 1.3 MB) (November 2006) - Prepared by ICF Consulting for FHWA, this report provides a compendium of traditional and innovative transportation-related control strategies. It identifies the emissions effects of the strategies on CO, PM10, PM2.5, NOx, VOCs, SOx, and NH3.
- Implications of the Implementation of the MOBILE6 Emissions Factor Model on Project-Level Impact Analyses Using the CAL3QHC Dispersion Model (or PDF, 1.9 MB) (August 2004) - Prepared by ICF Consulting for FHWA, this report discusses how revisions to the MOBILE model affect the estimation of localized CO concentrations, including problems and difficulties in the interaction of MOBILE6 with CAL3QHC, as well as recommendations for addressing these issues. In addition, this report discusses how the implementation of MOBILE6 impacts screening assessment procedures.
