(1) Duly executed certifications to the criteria set forth in paragraph (a) of this section; and
(2) Exhibits containing the basis for the certifications submitted under this section (including those factual and analytical materials deemed by the petitioner to be sufficient to support its certifications to this general requirement.)

Code of Federal Regulations

Note: In meeting this general requirement, OFE will require a petitioner to examine only mixtures of oil and coal and natural gas and coal, or, where petitioner wishes to examine an additional or substitute mixture, such other alternate fuels as OFE and the petitioner agree are reasonable to petitioner's circumstances.
