Senate Republicans are aiming to roll back funding for the Environmental Protection Agency’s more controversial regulations while reducing overall spending by the agency, according to an appropriations bill released Tuesday.

“On the regulatory side of the EPA budget, this bill makes cuts in areas where the EPA has clearly overstepped its bounds,” said Sen. Lisa Murkowski, R-Alaska, chairwoman of a Senate appropriations panel on the environment. Her panel introduced a $32 billion spending bill for EPA’s and Interior Department’s fiscal 2017 budgets.
