|For entities selling or distributing refrigerants for use in motor vehicles, there will be new restrictions for R-134a and other substitute refrigerants sold after Jan. 1, 2018. The rule establishes certification requirements for buying large containers of refrigerant and mandates that small containers include a self-sealing valve.
Under the new requirements, anyone purchasing a substitute refrigerant for R-12 in a greater-than-two-pound container must provide the seller with evidence that the technician has a Section 609 Technician Certification. If the purchaser is not certified and is buying the refrigerant on behalf of a service facility, the seller must be presented with evidence that one or more technicians at the facility are certified.
Refrigerant wholesalers must retain an invoice listing the name of the purchaser, date of sale and quantity purchased. The wholesaler is not required to confirm any technician certification, but EPA is recommending that wholesalers obtain a statement certifying that the cylinders are to be resold to certified technicians.
Individuals do not need to have certification in order to purchase small cans (under two pounds) of R-134a. However, all cans produced after Jan. 1, must come equipped with a self-sealing valve capable of preventing the container from venting refrigerant after it is removed from the charging valves. Despite this new requirement, retailers are permitted to sell off their existing inventory of small cans that do not have the self-sealing valves, as long as they were purchased prior to Dec. 31, 2017.
