Senator Roy Blunt (R-MO) and Representatives Sam Graves (R-MO), Vicky Hartzler (R-MO), Billy Long (R-MO), Blaine Luetkemeyer (R-MO), and Ann Wagner (R-MO) sent a letter to President Obama May 20 opposing the Environmental Protection Agency’s proposed GHG rules for new power plants. The group urged the agency to revise the rules to differentiate between sources since the rule is expected to raise plant construction cost by 80 percent for the coal industry.
