SAN DIEGO COUNTY AIR POLLUTION CONTROL DISTRICT


RULE 26.1. EMISSION REDUCTIONS CALCULATIONS

(Effective 2/16/83)

Emission reductions from a source shall be based on the actual operating conditions of the source averaged over the two consecutive years immediately preceding the date of application, or such other period as may be deemed more representative by the Air Pollution Control Officer provided such period is not less than two consecutive years unless the Air Pollution Control Officer determines a shorter period is more representative of emissions of the source and when that shorter period is within the two years immediately preceding the receipt of the application. Emission reductions from the shutdown of a source in operation for less than one year shall not be eligible for banking. Emissions in excess of any laws, rules, regulations, permit conditions, or orders of the District, the California Air Resources Board, or the Federal Environmental Protection Agency which occurred during the period used to determine the emission reductions shall not be considered. Emissions in excess of a standard and which are authorized by a variance shall not be considered. The ERCs for nonattainment pollutants shall not include reductions which would have occurred had RACT been applied. Except as stated above, emission reduction calculations shall be made pursuant to Rule 20.1.
