U.S. Sen. David Vitter (R-La.), top Republican on the Environment and Public Works Committee, and Sen. James Inhofe (R-Okla.), today sent a letter to Gina McCarthy, Administrator of the Environmental Protection Agency (EPA), following the Agency's Office of Atmospheric Programs' request for public engagement in the Interagency Special Report on the Impacts of Climate Change on Human Health in the United States (Report). In the letter, the Senators request clarification regarding EPA's role in developing the Report and insists the Agency be transparent.

"The EPA must be held to a high level of transparency throughout the process of developing this report - which is mandated to be completely evidence-based," said Vitter. "This will likely be used as a cornerstone of the President's far-left environmentalist agenda, and so the focus must be on fact-based, independently peer-reviewed, sound science and subsequent cost-benefit analyses."

In the letter, Vitter and Inhofe request details regarding the procedures and reviews being performed by EPA to contribute to the Report.

The Report, which is part of the President's Climate Action Plan, is tentatively scheduled to be finalized and published in late 2015, coinciding with the United Nations Framework Convention on Climate Change (UNFCC) Conference of the Parties (COP) during which a new treaty of global goals to lower greenhouse gas emissions will be developed.

In July 2013, EPW Republicans released a report entitled, "Critical Thinking on Climate Change: Questions to Consider Before Taking Regulatory Action and Implementing Economic Policies."
