RULE 20.7. STANDARDS FOR AUTHORITY TO CONSTRUCT-PROTECTION OF CLASS I AREAS (Adopted 9/19/84: EPA Delegation 11/21/85)

(a) Except as provided in Section (b) of this rule, the Air Pollution Control Officer shall deny an Authority to Construct for a new major source or a major modification, or a modification at an existing major source which is located within 10 km of a Class I area, which new or modified source would increase ambient pollutant concentration within any Class I area in the District or adjoining Districts by one microgram per cubic meter (24-hour average) or more of a pollutant other than a pollutant for which the San Diego Air Basin is designated as non-attainment, under Section 107(d)(1) of the Clean Air Act, unless the following requirements are met:

  1. The new major source or major modification is constructed with best available control technology as defined in Rule 20.1(b)(8).
  2. The applicant demonstrates by modeling [as defined in Rule 20.1(b)(25)] that the emissions increase from the new or modified stationary source would not cause the violation of any national ambient air quality standard or any applicable air quality increment.(3)Before granting or denying an Authority to Construct for any new or modified stationary source subject to this rule the Air Pollution Control Officer shall require the applicant to meet all requirements of Rule 20.3(e).
  3. The applicant has provided the Air Pollution Control Officer with analysis of impairment to visibility, soils, vegetation, and air quality related values (as specified by the Federal Land Manager) that may occur in a Class I area as a result of the new or modified source, and the Air Pollution Control Officer has determined that the new or modified source would not adversely impact visibility, soils, vegetation, and air quality related values in the Class I area. Analysis of impairment to visibility, soils, vegetation, and air quality related values shall be conducted according to the methods and procedures approved by the federal Environmental Protection Agency.
  4. Sufficient emission offsets have been provided in accordance with Rule 20.1 by the owner or operator of the stationary source to demonstrate that a net improvement in air quality would result in generally that portion of the Class I area the source will impact. This demonstration shall be required for only those pollutants for which the San Diego Air Basin is designated attainment.

(b) The Air Pollution Control Officer shall deny an Authority to Construct for a new or modified stationary source subject to the requirements of Section (a) of this rule where it has been demonstrated by the Federal Land Manager that granting of the Authority to Construct would authorize emissions which would have an adverse impact on the visibility, soil, vegetation, and air quality related values of a Class I area, provided that such demonstration is completed prior to the termination of the public comment period pursuant to the public notice required by Subsection (a)(3) above and that the Air Pollution Control Officer concurs with that demonstration.
