Section 608:

Under Section 608 of the CAA, the EPA has established regulations (40 CFR Part 82, Subpart F) that:

  • Require service practices that maximize recovery and recycling of ozone-depleting substances (both chlorofluorocarbons [CFCs] and hydrochlorofluorocarbons [HCFCs] and their blends) during the servicing and disposal of air- conditioning and refrigeration equipment.
  • Set certification requirements for refrigerant recycling and recovery equipment, technicians, and refrigerant reclaimers.
  • Restrict the sale of refrigerant to certified technicians.
  • Require persons servicing or disposing of air-conditioning and refrigeration equipment to certify to EPA that they have acquired refrigerant recovery and/or recycling equipment and are complying with the requirements of the rule.
  • Require the repair of substantial leaks in air-conditioning and refrigeration equipment with a refrigerant charge greater than 50 pounds.
  • Establish safe disposal requirements to ensure removal of refrigerants from goods that enter the waste stream with the charge intact (e.g., motor vehicle air conditioners, home refrigerators, and room air conditioners).





Significant New Alternatives Policy (SNAP)

Under Section 612 of the Clean Air Act (CAA), EPA’s Significant New Alternatives Policy (SNAP) program reviews substitutes within a comparative risk framework in several industrial sectors including Foam Blowing Agents and Refrigeration & Air Conditioning.

Read More...

Summary: Under Section 612 of the Clean Air Act (CAA), EPA’s Significant New Alternatives Policy (SNAP) program reviews substitutes within a comparative risk framework in several industrial sectors including Foam Blowing Agents and Refrigeration & Air Conditioning. The SNAP program does not provide a static list of alternatives but instead, evolves the list as EPA makes decisions that are informed by its overall understanding of the environmental and human health impacts as well as its current knowledge about available substitutes. Section 612 also provides that EPA must prohibit the use of a substitute where EPA has determined that there are other available substitutes that pose less overall risk to human health and the environment.

Rules: The following rules list substitutes that have been determined unacceptable, acceptable to use conditions, and acceptable subject to narrowed use limits. Substitutes that are acceptable without restriction are listed below in Notices of Acceptability

Original First Rule

Publication Date: March 18, 1994
Effective Date: April 18, 1994
Federal Register Citation: 59 FR 13044

Description
This final rule promulgates the U.S. Environmental Protection Agency's (EPA) program for evaluating and regulating substitutes for ozone-depleting chemicals being phased out under the stratospheric ozone protection provisions of the Clean Air Act (CAA). In section 612 of the CAA, the Agency is authorized to identify and restrict the use of substitutes for class I and II ozone-depleting substances where the Administrator has determined that other alternatives exist that reduce overall risk to human health and the environment. EPA is referring to the program that provides these determinations as the Significant New Alternatives Policy (SNAP) program. The intended effect of this final rule is to expedite movement away from ozone-depleting compounds by identifying substitutes that offer lower overall risks to human health and the environment.

Protection of Stratospheric Ozone: Proposed New Listings of Substitutes; Changes to Listing Status; and Reinterpretation of Unacceptability for Closed Cell Foam Products under the Significant New Alternatives Policy Program; and Revision of Clean Air Act Section 608’s Venting Prohibition for Propane

Summary: Pursuant to the U.S. Environmental Protection Agency's (EPA) Significant New Alternatives Policy (SNAP) program, this action proposes to list a number of substances as acceptable, subject to use conditions; to list several substances as unacceptable; and to modify the listing status for certain substances from acceptable to acceptable, subject to narrowed use limits, or to unacceptable. Specifically, this action proposes to list as acceptable, subject to use restrictions, propane and HFO-1234yf in the refrigeration and air conditioning, and 2-bromo-3,3,3-trifluoroprop-1-ene in the fire suppression and explosion protection sectors; to list as unacceptable certain hydrocarbons and hydrocarbon blends in specific end-uses in the refrigeration and air conditioning sector; and to modify the listing status for certain high-global warming potential alternatives for certain end-uses in the refrigeration and air conditioning, foam blowing, and fire suppression and explosion protection sectors. This action also proposes to exempt propane in certain refrigeration end-uses from the Clean Air Act section 608 prohibition on venting, release, or disposal on the basis of current evidence that its venting, release, or disposal does not pose a threat to the environment. In addition, this action proposes to apply unacceptability determinations for foam-blowing agents to closed cell foam products and products containing closed cell foam that are manufactured or imported using these foam-blowing agents. This action also proposes to clarify the listing for Powdered Aerosol D (Stat-X®), which is currently listed as both acceptable and acceptable subject to use conditions, by removing the listing as acceptable subject to use conditions.

Protection of the Stratospheric Ozone: Update to the Refrigerant Management Requirements under the Clean Air Act

Summary: The Clean Air Act prohibits the knowing release of ozone-depleting and substitute refrigerants during the course of maintaining, servicing, repairing, or disposing of appliances or industrial process refrigeration. The existing regulations require that persons servicing or disposing of air-conditioning and refrigeration equipment observe certain service practices that reduce emissions of ozone-depleting refrigerant. This proposed rule would update those existing requirements as well as extend them, as appropriate, to non-ozone-depleting substitute refrigerants, such as hydrofluorocarbons. The proposed updates include strengthening leak repair requirements, establishing recordkeeping requirements for the disposal of appliances containing five to 50 pounds of refrigerant, changes to the technician certification program, and changes for improved readability, compliance, and restructuring of the requirements. As a result, this action would reduce emissions of ozone-depleting substances and gases with high global warming potentials.

Protection of Stratospheric Ozone: Adjustments to the Allowance System for Controlling HCFC Production, Import, and Export

Summary: EPA is proposing to adjust the allowance system controlling U.S. consumption and production of hydrochlorofluorocarbons (HCFCs) as a result of a recent court decision vacating a portion of the rule titled ‘‘Protection of Stratospheric Ozone: Adjustments to the Allowance System for Controlling HCFC Production, Import, and Export; Final Rule.’’ EPA interprets the court’s vacatur as applying to the part of the rule that establishes the company-by company baselines and calendar-year allowances for HCFC–22 and HCFC– 142b. Following the August 5, 2011 interim final rule allocating allowances for 2011, this action proposes to relieve the regulatory ban on production and consumption of these two chemicals following the court’s vacatur by establishing company-by-company HCFC–22 and HCFC–142b baselines and allocating production and consumption allowances for 2012–2014.
