Non-ozone Depleting Substances
Non-ozone depleting substances (ODS) do not deplete the earth’s protective ozone layer. Products that normally contain ozone depleting substances should be replaced with functionally similar products that contain non-ozone depleting substances. The Environmental Protection Agency (EPA) established standards regarding the use and disposal of ODS under the authority of Section 602(a) of the Clean Air Act.
Federal Acquisition Regulation (FAR) Part 23 pertains to ODS:
- FAR 23.803 requires agencies to minimize procurement of ODS and to give preference to suitable, safe alternatives, and
- FAR 23.804 requires the insertion of contract clauses regarding ODS and service of refrigeration equipment and air conditioners using ODS.
EO 13693 requires federal agencies to purchase products containing acceptable substitutes for ozone-depleting substances used in industrial sectors that include air conditioning and refrigeration; fire suppression; cleaning solvents; foam blowing agents; aerosols; adhesives, coatings and inks; sterilants; and tobacco expansion.
In November 2016, DOD, GSA and NASA issued a final rule amending the FAR to implement Executive branch policy to procure, when feasible, alternatives to high global warming potential hydrofluorocarbons. The final rule includes four revised contract clauses:
52.223-11 Ozone-Depleting Substances and High Global Warming Potential Hydrofluorocarbons requires Contractors to label products that contain or are manufactured with ozone-depleting substances. Contractors are also required, for equipment and appliances that normally each contain 50 or more pounds of hydrofluorocarbons, to track and report on an annual basis the amount of hydrofluorocarbons contained in equipment and appliance delivered to the Government.
52.223-12 Maintenance, Service, Repair, or Disposal of Refrigeration Equipment and Air Conditioners requires Contractors to reduce the use, release, or emissions of high global warming potential hydrofluorocarbons under the contract. Contractors are also required, for equipment and appliances that normally each contain 50 or more pounds of hydrofluorocarbons, to track and report on an annual basis the amount of hydrofluorocarbons contained in equipment and appliance delivered to the Government.
52.223-20 Adhesives requires Contractors to reduce its use, release or emissions of high global warming potential hydrofluorocarbons, where feasible, from aerosol propellants or solvents under the contract.
52.223-21 Foams requires Contractors to reduce its use, release or emissions of high global warming potential hydrofluorocarbons, where feasible, from foam blowing agents under the contract.
Find and Purchase
The EPA created the SNAP program to evaluate and regulate substitutes for ozone-depleting chemicals being phased out under the stratospheric ozone protection provisions of the Clean Air Act. SNAP has listed substitutes for certain product categories. Non-compliant options also remain available for purchase, so remember to make sure to request a non-ODS alternative when ordering. The category list below links to the EPA's List of Substitutes:
- Refrigeration and Air Conditioning;
- Foam Blowing Agents;
- Cleaning Solvents;
- Fire Suppression and Explosion Protection;
- Aerosols, Solvents, and Propellants;
- Tobacco Expansion; and
- Adhesives, Coatings and Inks.
