Evaluation of Airport Emissions within State Implementation Plans

Description:

Based on the latest available science, the EPA regularly updates its national ambient air quality standards (NAAQS) for certain pollutants (called criteria pollutants). The agency categorizes all areas of the country as in attainment or non-attainment zones for each of the NAAQS (areas that were in non-attainment but have subsequently met the standards are considered to be in a “maintenance” area). Several airports are currently in a maintenance or non-attainment area for one of the covered pollutants, and others may be brought into non-attainment based on future NAAQS. These airports must ensure that their emissions (from operations and construction) are addressed in their state implementation plan. In addition, the costs and operational impacts of moving from a less to a more stringent designation are not well understood (for example, moving from moderate to severe non-attainment for ozone). The ACRP Report 84: Evaluation of Airport Emissions within State Implementation Plans was published in 2013, but the industry has expressed a need for an update to this guidance according to current and evolving best practices.

Objective:

The objective of this research is to update ACRP guidance on how airports can ensure their emissions are incorporated into their states' implementation plans with current best practices.
