The White House said Monday that it would likely veto a GOP-led plan to overturn Environmental Protection Agency regulations that require cuts in mercury and other toxic emissions from coal-fired power plants.

The Senate is slated to vote this week on Sen. James Inhofe’s (R-Okla.) resolution to overturn the regulations that were finalized late last year.

A formal White House “statement of administration policy” issued Monday says Inhofe’s plan, if successful, would “cause substantial harm to public health and undermine our nation’s longstanding commitment to clean up pollution from power plants.”
