Indirect Source Rule

Indirect Source Rule

This emission control strategy aims to mitigate emissions associated with the construction and operation of indirect sources.  Indirect sources include activities associated with facilities, structures, buildings, et cetera, which can reasonably be expected to cause or induce substantial mobile source activity, that result in emissions of air pollutants that might reasonably be expected to interfere with the attainment and maintenance of the national ambient air quality standards.

The goal of preparing an Indirect Source Rule(s) to be endorsed by the RAQC Board and considered/adopted as a regulation by the Air Quality Control Commission are to reduce emissions from high traffic locations, where the construction or operation of a facility, building, or structure attracts, or may attract, mobile sources of pollution.  The ISR project will conduct a series of phased analyses to provide data and information for use in drafting a subsequent ISR proposal.  The project sponsors are utilizing the following steps in developing an ISR:

          • -Identify and review existing Indirect Source Rules in other regions around the country;
          • -Identify potential benefits and roadblocks for establishing a program in the DM/NFR region; and
          • -If appropriate measures are identified for development, then draft a regulatory framework to establish a program in the DM/NFR region.
