Henry A. Waxman, chair of the House Oversight and Gov't Reform Comm., reacted to EPA's decision to undertake an Advance Notice of Proposed Rulemaking regarding the endangerment finding by saying:
“This is a transparent delaying tactic and a major reversal of EPA’s position. In December, Administrator Johnson found that CO2 emissions endanger the environment and proposed new standards for motor vehicles. Today’s action repudiates those efforts.
I sent a letter to Administrator Johnson on March 12, 2008, that described his December determinations and the extensive EPA effort that supported his actions. Shortly thereafter, Inside EPA reported that the Heritage Foundation circulated a memorandum to Senators urging them to call the White House. According to the memo from the Heritage Foundation, which Inside EPA released, Senators were urged to ask for ‘EPA to issue an Advance Notice of Proposed Rulemaking seeking information on the issues involved in a CO2 endangerment finding and resulting carbon dioxide regulations and not make an endangerment finding.’ This is precisely the action announced today.
“The Bush Administration is recklessly abandoning its responsibility to address the global warming crisis.”
Heritage suggested that the Senators tell the Administration to conduct the ANPR to allow for consideration of the "potential cost and burden" of the endangerment finding, notwithstanding the Clean Air Act's requirement that the finding focus exclusively on human health and public welfare.
