This paper describes an effort by the Emission Control Technology Division of the Environmental Protection Agency (EPA) to suggest a range of concern for methanol (CH3OH) 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 uses the results from two EPA contracts to apply this methodology specifically for an evaluation of methanol. Mathematical models previously designed for various exposure scenarios (such as enclosed spaces, expressways, and street canyons) were used to calculate the ambient air concentrations resulting from a range of potential mobile source methanol emissions. In conjunction with this work, a health effects literature search for methanol was conducted by Midwest Research Institute under contract to EPA to aid in the determination of the suggested range of concern. It must be mentioned that the range of concern for methanol suggested in this report is based on its toxicological properties and not its photochemical reactivity nor any possible carcinogenic effects.
