Any new or modified source that emits or has the potential to emit a “significant” amount of any pollutant located in a nonattainment or maintenance area is subject to the offset requirements. These offsets are required to ensure reasonable progress toward attainment of the applicable NAAQS.
Emission Reduction Credits (ERCs) are “bankable” if they are surplus, permanent, quantifiable, and federally enforceable. The baseline for determining ERCs is the State Implementation Plan (SIP) emission limitations in effect at the time the application to construct or modify a source is filed. Therefore, credit for emission offset purposes may be allowed for an existing control that goes beyond the requirements of the SIP.
