Purpose

This Subchapter establishes a mechanism for the generation and use of emission reduction credits (ERCs) to offset project emission increases associated with construction of a new major stationary source or a major modification as defined in OAC 252:100-8-31. The incorporation of offsets into a PSD permit is intended to reduce the impact of project emissions to ambient air quality to ensure that the project does not cause or contribute to a violation of any national ambient air quality standard.
