| Abstract |
This paper describes an effort by the Emission Control Technology Division of the EPA to establish a range of concern for ammonia (NH3) emissions from mobile sources. In accordance with section 202(a)(4) of the Clean Air Act (CAA), and due to a concern within industry as to what emission levels will be used as the basis for the evaluation of current and future technologies, a methodology was developed in order to bracket a range of concern for various unregulated pollutants. This paper coordinates the efforts from two EPA contracts in order to use this methodology specifically for an evaluation of NH3. Mathematical models were previously designed or adjusted for various exposure scenarios (such as enclosed spaces, expressways, and street canyons) and were used to calculate the ambient air concentrations resulting from various mobile source NH3 emission factors. In conjunction with this, an NH3 health effects literature search was conducted to aid in the determination of the final range of concern. This search provides adequate evidence to support the chosen limits of the range. |
