Subpart Q, which operates in lieu of Parts 260 to 270, covers lower flammability spent refrigerants (not highly flammable ones such as butane, isobutane, methane, propane or propylene) that exhibit ignitability and are recycled for reuse in the United States (processed to remove contamination for use again, not burned for energy, used in a manner constituting disposal or sham recycled); other ignitable spent refrigerants remain under Parts 260 to 270 once recovered or disposed of. Persons who recover or recycle them for reuse in the same owner's equipment or under the motor vehicle air conditioning rules, or who send them off site for recycling, must use equipment certified for that refrigerant and appliance under 40 CFR 82.36 or 82.158 and must not accumulate speculatively (261.1(c)). Persons receiving them from off site (other than transfer facilities storing under ten days) must use certified recovery equipment, meet the emergency preparedness and response requirements of Part 261 Subpart M, and not accumulate speculatively; reclaimers receiving them for recycling must also maintain EPA certification under 82.164, with the speculative accumulation limit applying from the calendar year beginning January 1, 2029.
