The U.S. Environmental Protection Agency’s (EPA) proposed a rule to approve a new substitute refrigerant, HFO-1234yf, under the Significant New Alternatives Policy (SNAP) Program. EPA is being urged to look at the total lifecycle of the fluid, and consider all ramifications that may occur from the use, and ultimately, the disposal of the new fluid.
Detailed in the Federal Register, the proposed rule on October 19, 2009 (74 FR 53445), the EPA proposed to find HFO-1234yf acceptable as an alternative refrigerant for motor vehicle air conditioning systems, subject to use conditions. There are several areas of concern, to include the potent adverse consequences from the use of the new refrigerant. What about its recyclability, safety, and feasibility? What are the potential effects on the environment, automotive industry employees and the general public?
As advocates for the professional automotive recycling industry, ARA’s concerns target the storage, disposal, occupational hazard, internal cost associated with specialized equipment, impact on air quality, and storm water run-off requirements. The specific questions raised highlight the need for further information and in-depth research for handling this new fluid during the dismantling process of an end-of-life vehicle.
