More information about EPA’s leak repair requirements under Section 608, including a copy of the proposed rule, is available at http://epa.gov/ozone/ title6/608/leak.html. **SUPPLEMENTARY INFORMATION :**  Background

The statutory and regulatory background is described in detail in the December 15, 2010, notice of proposed rulemaking (75 FR 78558). EPA has proposed to lower the leak repair trigger rates for comfort cooling, commercial refrigeration, and industrial process refrigeration and air-conditioning equipment with refrigerant chargesgreater than 50 pounds of ozonedepleting substances. This action proposes to streamline existing required practices and associated reporting and recordkeeping requirements by establishing similar leak repair requirements for owners or operators of comfort cooling, commercial refrigeration, and industrial process refrigeration appliances. This action also proposes to reduce the use and emissions of class I and class II controlled substances (such as but not limited to CFC–11, CFC–12, HCFC–123, and HCFC–22) by requiring verification and documentation of all repairs, retrofit or retirement of appliances that cannot be sufficiently repaired; replacement of appliance components that have a history of failures; and recordkeeping of the determination of the full charge and the fate of recovered refrigerant.

This Action

EPA has received a request to provide additional time for public comment on the proposed rule. We believe that the request is reasonable and that a further 30 days for additional public comment is appropriate, since it will provide affected entities with necessary time to complete analysis and comment on the proposal. This action therefore reopens the comment period for 30 days. We intend to issue a final rule as expeditiously as possible following consideration of the comments and information we receive.

Dated: February 16, 2011. Gina McCarthy, Assistant Administrator, Office of Air and Radiation.
