Air Quality Modeling Analysis

Air Quality Analysis

Two types of air quality analysis were performed in support of the Re-Evaluation – emission inventories and dispersion analysis. The emission inventories provide an indication of total air pollutant emissions (carbon monoxide, nitrogen oxides, sulfur oxides, volatile organic compounds, particulate matter less than or equal to 10 micrometers, and particulate matter less than or equal to 2.5 micrometers) with the 2015 and 2020 Interim Conditions for Airport-related emission sources and non-Airport motor vehicle traffic.

The dispersion modeling analysis evaluates local criteria pollutant concentrations due to Airport and non-Airport-related emission sources for direct comparison to the National Ambient Air Quality Standards for carbon monoxide, nitrogen dioxide, sulfur oxides, particulate matter less than or equal to 10 micrometers, and particulate matter less than or equal to 2.5 micrometers on and in the vicinity of the Airport.

The emission inventories and dispersion analysis were performed using the following Federal Aviation Administration (FAA) and US Environmental Protection Agency (USEPA) computer models:

The FAA-required EDMS is a model designed to assess the air quality impacts at airports. The USEPA-approved AERMOD dispersion model is designed to assess air quality impacts from emission sources such as those found at airports. The USEPA's MOBILE model is a tool for estimating emission factors for cars, trucks, and motorcycles. Finally, the USEPA's NONROAD model is used to estimate emission factors for nonroad vehicles, equipment, and engines.
