(a) Except as provided in subdivision (b), to the extent permissible under federal law, and notwithstanding any state or local new source review or prevention of significant deterioration rule or regulation, at the request of an applicant, a district shall issue permits for the construction of a project which burns municipal waste, landfill gas, or digester gas, if all of the following conditions are met:

1. (1) The project produces less than 50 megawatts of electricity, except as provided in paragraph (4).
2. (2) The project will utilize the appropriate degree of pollution control technology (BACT or LAER) required by the new source review rule of the district.
3. (3) The project applicant has, in the judgment of the district, made a good faith effort to secure all available emission offsets to mitigate the impact of the project, but sufficient offsets or other mitigation measures are not available. The applicant, however, is required to secure all the offsets which are available to mitigate the air quality impact of the project, except for projects which constitute a modification to an existing source under the district’s new source review rule, in which case the applicant is only required to provide offsets from facilities which the applicant owns or operates within the air basin.
4. (4) The project produces 50 megawatts or more, but less than 80 megawatts, of electricity, meets the requirements of paragraphs (2) and (3), is located in a district whose state implementation plan revisions have been approved by the Environmental Protection Agency and that has attained, or is reasonably expected to attain, national air quality standards for any criteria pollutant for which sufficient growth allowances are available in the air quality maintenance plan or, in the event the project would cause any criteria pollutant to exceed the available or possible future growth allowance, the applicant secures offsets in an amount equal to the excess in the growth allowance, and processes municipal wastes from one or more municipalities. Any project under this paragraph shall comply with applicable prevention of significant deterioration rules and regulations.
