There’s a lot at stake in the elections on Tuesday, including which party controls the U.S. House and whether Congress will begin hearings and oversight of the Trump Administration’s rollback of environmental regulations.The Republican-led U.S. House has passed 36 different anti-environmental bills and amendments the last two years, according to the National League of Conservation Voters. This includes legislation that would undermine the Chesapeake Bay cleanup by stripping EPA of its authority to penalize states that fail to meet pollution reduction targets.The House's majority also voted in favor of legislation that would – among other things – reduce protections for wetlands and streams; allow more methane pollution from oil and gas drilling sites; and override local bans on the use of pesticides in lawn care, such as have been adopted by Howard and Montgomery counties in Maryland.Congressman John Sarbanes, a Maryland Democrat, voted against all these bills and is running for re-election in a district that includes parts of the Baltimore area. “The House has been on a crusade to overturn regulations that protect our environment,” Sarbanes said.
