“Later today, more than 18 GOP governors are going to release a letter addressed to President Obama detailing ways in which the regulatory agenda pursued by the Obama Administration and the EPA are curtailing economic growth in the states and threatening America’s long-term prosperity,” Republican Governors Association spokesman Mike Schrimpf tells First Read.

Excerpt from the letter: “The uncertainties caused by international events that are well beyond the Administration’s control are further compounded by the unreasonably aggressive regulatory agenda being pursued by the U.S. Environmental Protection Agency (EPA).  As the stewards of our states’ natural resources, we share the broad goals of the EPA to protect our air and water. However, we wish to express our strong concerns over the contents and timing of many of the recently adopted and pending regulations, which together could seriously impact energy supply, reliability, and affordability for the residents, small businesses, and manufacturers in our states and across the country. … the EPA is simultaneously developing and implementing a number of regulatory and policy initiatives with extremely short and converging compliance deadlines within the next five years which will significantly impact the energy industry, increase burdensome costs to consumers, and hurt the competitiveness of U.S. manufacturers.”

And the group writes that it “would discourage” tapping the country strategic oil reserve: “The SPR should only be tapped when we face both international crisis and domestic decline in resource capacity. We have not yet reached this point.”

RGA Vice Chair/Virginia Gov. Bob McDonnell (R) will be on CNBC’s Squawk Box at 8:35 a.m. to talk energy.
