The settlement resolves allegations that Safeway violated the federal CAA by failing to promptly repair leaks of HCFC-22, a hydro-chlorofluorocarbon that is a greenhouse gas and ozone-depleting substance used as a coolant in refrigerators, and failed to keep adequate records of the servicing of its refrigeration equipment. Safeway will now implement a corporate refrigerant compliance management system to comply with stratospheric ozone regulations. In addition, Safeway will reduce its corporate-wide average leak rate from 25 percent in 2012 to 18 percent or below in 2015. The company will also reduce the aggregate refrigerant emissions at its highest-emission stores by 10 percent each year for three years. The measures that Safeway has committed to are expected to prevent over 100,000 pounds of future releases of ozone-depleting refrigerants that destroy the ozone layer.
