However, the Agency did not promise to take regulatory action.

The EPA issued Significant New Use Rules (SNURs) for PFOS-related substances in 2002.   It also issued a SNUR for the use of perfluorinated chemicals in carpets and carpet aftercare products in 2013.  In addition, the Agency partnered with manufacturers in the US and globally to reduce or eliminate use of PFASs.  U.S. companies voluntarily phased out producing the chemicals between 2000 and 2002.  Foreign companies achieved a 95 percent reduction in PFOA and PFOA-related chemicals in the emissions from their facilities and in their products.

The EPA has also published drinking water health advisories for PFOA and PFOS.
