Is it true that the lead test kits that were recognized by EPA before September 1, 2010, are no longer recognized since that date?
No. The lead test kits that were recognized by EPA before September 1, 2010 did not automatically lose their recognition on September 1, 2010. As discussed in the 2008 RRP rule, prior to September 1, 2010, manufacturers seeking recognition of their lead test kit had to meet only the negative response criterion. EPA recognition of lead test kits meeting this criterion will last until EPA publicizes its recognition of a lead test kit that passes both the negative response and the positive response criteria.
