# Plain Language Summary: Stop Delta Tunnels Act

This bill would block the federal government from approving a major water infrastructure project in California called the Delta Conveyance Project. Specifically, it prevents the Army Corps of Engineers from issuing the environmental permit needed to move forward with the project. The Delta Conveyance Project is a proposed system of tunnels designed to move water from Northern California's Sacramento-San Joaquin Delta to Southern California, where it would supply water to farms and cities in the south.

The practical effect of this bill is straightforward: if it becomes law, the Delta Conveyance Project cannot proceed, at least not through the federal permitting process. This matters because California has been working on this project for years as a way to address water shortages in the state, particularly in agricultural regions and Southern California cities. Supporters of the project argue it would provide more reliable water supplies during droughts, while opponents worry it could harm the Delta's ecosystem, affect local water quality, and damage fish populations in the region.

For most Americans outside California, this bill wouldn't have a direct impact on daily life. However, for Californians—especially farmers who depend on irrigation water and residents of Southern California cities—this could mean continued water supply challenges during dry years. The bill essentially takes a federal decision-making tool off the table, which could either stop the project entirely or force it to pursue alternative approval pathways through state-level processes instead.

Stop Delta Tunnels Act

Stop Delta Tunnels Act This bill prohibits the U.S. Army Corps of Engineers from issuing a permit to discharge dredged or fill material into navigable waters for the proposed Delta Conveyance Project in California. The California Department of Water Resources proposed this project, which involves constructing new State Water Project diversion and conveyance facilities in the Sacramento-San Joaquin Delta. The proposal includes an underground tunnel to deliver water south of the delta.
