This bill requires the Secretary of the Army to create standardized procedures for reviewing applications from hydropower projects seeking permission to alter or occupy federal waterways. Specifically, the bill mandates that within one year of enactment, the Army Corps of Engineers must issue guidance that includes a standardized checklist of required materials, clear criteria for what makes an application complete, timelines for phased reviews, and procedures for escalating delayed applications to higher officials. The guidance must be developed in consultation with the Federal Energy Regulatory Commission, hydropower operators, and industry groups. The bill also restricts what the Army Corps can do during its review process, prohibiting detailed technical analysis of engineering calculations, requests for design modifications, and consideration of environmental standards that didn't exist before the application was submitted. The goal is to streamline and standardize the application review process for non-federal hydropower projects.
