In November and December, Congress voted on multiple bills to repeal the Clean Water Rule. When these votes occurred, hundreds of League members contacted their Senators and Representatives in opposition.

Both chambers passed one of those bills (SJ Res 22), which would not only repeal the rule but permanently prohibit the Army Corps of Engineers and Environmental Protection Agency from developing any future rule that would provide similar protections. If this bill became law, the threats to streams, wetlands, and drinking water would only grow and the confusion about which types of waters are protected by the Clean Water Act would persist.

The President vetoed this bill on January 20, and efforts in Congress to override that veto were unsuccessful.
