The Environmental Protection Agency published a proposed rule requiring the reporting of greenhouse gas emissions during the production of fluorinated heat transfer fluids on September 9. Originally issued in 2010, EPA intends to finalize the rule by the end of 2011, and is accepting public comments until October 11 on the practicality of implementing the reporting requirements by March 31, 2012. Other proposed revisions include measures to change how vented and leaked waste will be reported.
