Regulatory Background

In 1987, the United States and 22 other countries signed the Montreal Protocol which set in motion plans to reduce atmospheric loading of chlorine and other ozone depleting compounds so as to halt atmospheric ozone depletion. As of 2011, 196 of the world's countries had signed the Protocol.



On Nov. 15, 1990, the United States Congress adopted amendments to the Clean Air Act which described what provisions the United States would do to control emissions of ozone depleting compounds in order to abide by the Montreal Protocol. Some of the major CFC components of the Clean Air Act include:


  • manufacturers' phaseout of ozone depleting compounds;
  • excise tax on the sales of ozone depleting compounds;
  • prohibition on venting of ozone depleting compounds;
  • required use of recovery equipment during air conditioning and refrigeration service;
  • mandatory certification and training of service technicians;
  • prohibition on sales of refrigerants to non-certified technicians;
  • maximum allowable leakage rates for certain types of air conditioning and refrigeration equipment;
  • nonessential product usage;
  • labeling requirements of products containing ozone depleting compounds; and
  • safe alternative ozone depleting compound substitutes review.



On Dec. 17, 1992, the Colorado Air Quality Control Commission adopted Regulation No. 15 in order to meet the statutory requirements for the state Chlorofluorocarbon Program. Major program components in the regulation include:


  • prohibition of intentional releases of ozone depleting compounds;
  • registration of stationary equipment with 100 compressor horsepower or greater;
  • registration of equipment which contain 300 pounds or greater of an ozone depleting compound at sources that sell food for human consumption;
  • registration of all facilities which perform air conditioning or refrigeration service;
  • required leak checking of air conditioning systems and record keeping of service for automotive facilities; and
  • compliance with Section 608 of the Clean Air Act (40 CFR Part 82 Subpart F)
