2011 Wisconsin Act 146 Section 34 repealed Wis. Stat. § 101.177 effective May 4, 2012. Accordingly, the Department of Safety and Professional Services no longer has the authority to regulate the duties of a refrigerant handling technician. If you have this certification, it will become void after May 4, 2012.
Please be aware that ozone-depleting refrigerants are still regulated by the Wisconsin Department of Natural Resources for the transport or salvage of refrigeration or air-conditioning equipment. The U.S. Environmental Protection Agency also has applicable regulations in this area pertaining to refrigerant sales, distribution and reclamation.
