REGULATION OF INDIRECT SOURCES OF AIR POLLUTION

The Division of Air Pollution Control, Illinois Environmental Protection Agency, has conducted an ambient air quality monitoring project focusing on carbon monoxide levels in and around several indirect sources. An analysis of the data indicates that highway types of pollutant emissions have the greatest impact on receptors in the vicinity of indirect sources. This implies that the principal, localized constraint on the siting of indirect sources will be the carbon monoxide generated on public roadways servicing those indirect sources. Clearly, adequate procedures must be developed to link such highway types of emissions to pollutant concentrations. Area- source and line-source models were tested by using the data generated during the monitoring project. Favorable results were achieved by using the line-source model. The proper siting of indirect sources involves the allocation of roadway capacity by the governmental units that are responsible for transportation network design and that work in conjunction with regional planning bodies. A regulatory structure is suggested that emphasizes a regional approach, and an example of an air quality allocation scheme is given. The methodology is applicable to all automotive air pollutants although, in general, localized sensitivity is lost for nitrogen dioxide and photochemical oxidants.
