US HB4776

Amends the National Environmental Policy Act of 1969 to clarify it is a purely procedural statute that does not mandate specific environmental outcomes or confer substantive rights beyond procedural requirements

Establishes strict deadlines for federal environmental reviews: agencies must notify applicants within 60 days whether applications are complete, issue notices of intent within 60 days of completeness determination, and issue final agency actions within 30 days of completing environmental assessments or impact statements

Limits scope of environmental review to effects with a "reasonably close causal relationship" to the project, prohibiting consideration of speculative, attenuated, or geographically/temporally separate effects

Restricts judicial review by requiring claims be filed within 150 days, limiting remedies to remand without vacatur or injunction, requiring courts to afford "substantial deference" to agencies, and mandating courts issue final judgments within 180 days

Allows agencies to rely on state, tribal, or previously completed federal environmental reviews in lieu of new NEPA analysis, and extends programmatic environmental document validity from 5 to 10 years
