Representative Bob Latta (R-OH) offered this amendment to H.R. 2401, the deceptively titled Transparency in Regulatory Analysis of Impacts on the Nation Act of 2011(TRAIN Act), to eliminate a central underpinning of the Clean Air Act—affirmed by the U.S. Supreme Court in 2001—that clean air standards must be based on what public health science tells us is safe to breathe. This amendment would require the EPA to define healthy air based on the “feasibility and cost” to polluting industries, and would compel the EPA to accept standards that fail to protect public health. On September 23, the House adopted the Latta amendment by a vote of 227-192 (House roll call vote 738). NO IS THE PRO-ENVIRONMENT VOTE. The Senate has taken no action on legislation containing language from the Latta amendment.
