House memos preview Wednesday showdown on EPA climate rules

The memo says the legislation would have a suite of far-reaching effects, such as threatening the national renewable fuels standard and creating legal uncertainty about the status of EPA’s existing motor vehicle standards.

The measure would also, according to the memo from Waxman and Energy and Power subcommittee ranking member Bobby Rush (D-Ill.), “call into question EPA’s authority to implement voluntary programs to reduce greenhouse gas emissions,” and “create new litigation opportunities for opponents of regulation of conventional pollutants."

The Democratic memo more broadly criticizes Upton's bill, noting it upends EPA’s 2009 finding that greenhouse gases are a threat to humans. The finding is the legal foundation for climate change regulations.

“Legislatively repealing the scientific determination directly conflicts with the consensus of climate scientists and the world's most authoritative scientific organizations,” the memo notes.

Wednesday’s hearing in the Energy and Power subcommittee will include testimony from EPA Administrator Lisa Jackson in what will be her first public clash with the new House GOP majority.

Other witnesses include Sen. James Inhofe (R-Okla.), who is working with Upton on efforts to stymie EPA climate regulations, as well as several industry officials, a public health advocate and others.
