The U.S. Environmental Protection Agency (EPA) announced a delay on a ban of the production and import of mid and long-chain chlorinated paraffins until mid-2017. Chlorinated paraffins (CPs) have long been used as additives in metalworking fluids, and groups such as the Chlorinated Paraffins Industry Association (CPIA) and the Independent Lubricant Manufacturers Association (ILMA) have been working to convince the EPA not to ban CPs at all. The ban was originally supposed to go into effect in May 2016, but the EPA announced the delay in order to give manufacturers time needed to transition.
