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 charges 

greater 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.

Assistant Administrator, Office of Air and 

Radiation.
