The petition or any supplement thereto required by OFE must include the following evidence:\n(1) If use of a method of fluidized bed combustion were to be required, evidence that the petitioner would be eligible for a permanent exemption for lack of alternate fuel supply, site limitations, environmental requirements, lack of adequate capital, or State or local requirements; or\n(2) Use of a method of fluidized bed combustion is not technically or economically feasible due to design or special circumstances.","path":["Title 10—Energy","CHAPTER II—DEPARTMENT OF ENERGY","SUBCHAPTER E—ALTERNATE FUELS","PART 503—NEW FACILITIES","Subpart B—General Requirements for Exemptions"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-10.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:24:09Z","sha256":"a6f3e0ad39831cb185088dc68c58a79e65cf96e3fe344a377352e176a0060eb4","source_id":"us-cfr","stale":true,"prev":"us/10-cfr-503.9","next":"us/10-cfr-503.11"},"notice":"GroundRules: Original legal text.
