SAN DIEGO COUNTY AIR POLLUTION CONTROL DISTRICT

RULE 20.4. STANDARDS FOR AUTHORITY TO CONSTRUCT MAJOR SOURCES (Effective 7/5/79: Rev. Effective 12/15/87)

(a) The Air Pollution Control Officer shall deny an Authority to Construct for any of the following sources which may emit or contribute to any air contaminant for which a national ambient air quality standard is exceeded unless all the requirements specified in this rule are met:

  1. Any new major source of organic compounds or any air contaminant for which there is a national ambient air quality standard.

  2. Any modification to an existing source which is major for any pollutant and where the modification would result in emissions increase of that pollutant by any of the following rates:

  3. POLLUTANT RATE
    Carbon monoxide 100 tons per year
    Sulfur oxides 40 tons per year
    Nitrogen oxides 40 tons per year
    Particulate 25 tons per year
    Ozone 40 tons per year of organic compounds
    Lead Compounds Including Elemental Lead 0.6 tons per year


    Any source that is major for organic compounds shall be considered major for ozone, and

  1. Any modification to a non-major source which if the modification were taken by itself would be a major source.

(b) The Air Pollution Control Officer shall deny an Authority to Construct to any source subject to the provisions of this rule unless the following conditions are met: [Rev. Effective 5/16/84]

  1. The owner or operator of the source has certified that all major stationary sources owned or operated by such person in the State are in compliance, or are on an approved schedule for compliance, with all emission limitations and standards applicable under the Federal Clean Air Act; and

  2. The implementation plan for the San Diego Air Basin approved by the EPA, is being carried out for the applicable pollutant; and

  3. The new or modified source is constructed to comply with the lowest achievable emission rate (LAER); and

  4. An air quality analysis has been conducted in accordance with Rule 20.3, and such analysis shows that the emissions resulting from the new or modified source may not be expected to interfere with the attainment and maintenance of any national ambient air quality standard; and

  5. The owner or operator of the source has provided sufficient emission reductions, to the satisfaction of the Air Pollution Control Officer, from existing sources to (i) offset any increase in emissions resulting from the new or modified source including increases due to fugitive and secondary emissions as indicated by an emissions profile, after the application of LAER, and (ii) demonstrate consistency with Reasonable Further Progress and provide net air quality benefit. Emission reductions provided to comply with this paragraph shall be evaluated consistent with Rule 20.1; and

  6. Emission offsets for carbon monoxide shall not be required if the applicant demonstrates to the satisfaction of the Air Pollution Control Officer that the national ambient air quality standard for carbon monoxide is not violated in the areas to be affected by emissions from the new or modified source, and the air quality analysis conducted in accordance with Rule 20.3 shows that carbon monoxide emissions from the new or modified source will not interfere with the attainment or maintenance of the carbon monoxide national ambient air quality standard and that such emissions will be consistent with Reasonable Further Progress; and

  7. The new or modified source will meet the requirements of all other applicable air pollution rules and regulations; and

  8. The owner or operator of a new or modified source which may emit organic gases, nitrogen oxides or carbon monoxide has submitted to the Air Pollution Control Officer an analysis of alternative sites for such proposed source, which demonstrates that benefits of the proposed source at a site selected by the applicant significantly outweigh the environmental and social costs imposed as a result of construction of the proposed source at other alternative locations. For the purpose of this analysis, not more than three alternative sites shall be selected with the approval of the Air Pollution Control Officer.
