Revisions to the Refrigerant Management Program's Extension to Substitutes (Draft)
Oct. 1, 2018
On 18 Nov 2016 EPA finalized a rule that updated the existing refrigerant management requirements and extended requirements previously applicable only to refrigerants containing an ODS to substitute refrigerants such as HFCs that are subject to the venting prohibition. EPA proposes revision of appliance maintenance and leak repair provisions so they apply only to equipment using refrigerant containing a class I or class II substance. Based on this proposed limitation, this document also proposes to revise the list of practices to be followed in order for refrigerant releases to be considered de minimis to clarify that the reference to following leak repair practices only applies to equipment that contains ODS refrigerant. EPA is taking comment on whether the 2016 Rule's extension of subpart F refrigerant management requirements to substitute refrigerants should be rescinded in full. EPA is proposing to extend by 6 to 12 mo the 1 Jan 2019 compliance date for when appliances containing only substitute refrigerants subject to the venting prohibition must comply with the appliance maintenance and leak repair provisions. Written comments must be received by 15 Nov 2018.
