WhatWhat’’s happening in PFOA related areas since 2000s happening in PFOA related areas since 2000

• 2000　3M discontinued PFOS related businesses• 2000 Fluoro Industry forms two industry associations (FMG and TRP)• 2003　U.S.EPA initiated process leading to ECA’s for testing on PFOA• 2006　U.S.EPA proposed 2010/2015 PFOA Stewardship Program.

Eight major fluorochemical companies participate• 2009 U.S.EPA announced a Long-Chain PFC Action Plan

(ban import C8 products and treated articles from 2016)• 2010 Stewardship Program companies achieved at least 95% reduction of 　

　PFOA from product releases and product content　• 2011　Classification: PFOA as Carcinogenicity 2, Reproductive Toxicity 1B• 2011　Fluoro Council formed• 2012 U.S.EPA announced three relevant SNURs

(Effective ban on C8 products in carpets)• 2012 U.S.FDA announced C8 products for food contact use on paper

were removed from interstate commerce by their manufacturers.• 2013　Europe designated PFOA as an SVHC• 2014 Germany (with Norway) planed to submit an Annex XV Restriction

dossier on Perfluorooctanoic acid (PFOA) by 17 October 2014• 2015 (Stewardship Program Participating companies virtually eliminate PFOA

and precursors from manufacturing releases and product content)

The value is theoretical number by calculation. Actual value on the fabric is fluctuated with atmosphere and treating conditions in the mill.
