The resources below are aimed at helping you recognize when permits are required for maintenance, rehabilitation, construction or demolition of dams. Other environmental requirements may include environmental assessments, alternative analyses, National Pollutant Discharge Elimination System (NPDES) permits, and erosion & sedimentation control permits.
