Nineteen Senate Democrats led by Sen. Tom Carper, top Democrat on the Environment and Public Works Committee, sent a letter Oct. 26 to Environmental Protection Agency Administrator Scott Pruitt asking for more information on the agency’s decision to repeal the Clean Power Plan.

The proposal, released by the agency earlier this month, relies heavily on skewed scientific and mathematical data in order to justify repealing the Clean Power Plan.

“Our review of the 2017 Repeal proposal reveals significant deficiencies associated with the cost-benefit analysis used to support the 2015 Rule’s repeal. At seemingly every turn, the 2017 Repeal proposal uses mathematical sleights of hand to overstate the costs of industry compliance with the 2015 Rule and understate the benefits that will be lost if the 2017 Repeal is finalized. Denying the science and fabricating the math may satisfy the agency’s paperwork requirements, but doing so will not satisfy the requirements of the law, nor will it slow the increase in frequency and intensity of extreme weather events, the inexorable rise in sea levels, or the other dire effects of global warming that our planet is already experiencing. It will also not improve our standing in the international community or bring certainty to power markets as states plan for their future energy needs,” the senators wrote.

“Your rejection of the scientific consensus that greenhouse gas pollution causes global warming is well-known. Additionally, we continue to await your response to the April 7, 2017 letter requesting more details about your views related to the cause of global warming and the agency’s plan to repeal and replace the 2015 Clean Power Plan Rule. Our review of the 2017 Repeal proposal only heightens our concerns.”

In April, reports showed that the analysis of EPA career staff regarding pending legislation was eliminated entirely from the official comments that the agency ultimately submitted to the Congressional Budget Office. In September, reports in The New York Times revealed that political appointees at EPA directed career scientists to delete the Clean Water Rule’s $500 million in economic benefits from a regulatory package that the agency submitted to the White House Office of Management and Budget for review. EPA has not responded to Senate inquiries on either of these reports.

The senators requested all documents, including but not limited to emails, memos, meeting notes and correspondence, sent or received by EPA that are related to EPA’s cost-benefit analysis for its 2017 Repeal of the Clean Power Plan no later than Dec. 1.
