LPDES Permits

Louisiana Pollutant Discharge Elimination System


Louisiana's Water Quality Regulations (LAC 33:Chapter IX) require permits for the discharge of pollutants from any point source into waters of the state of Louisiana.  This surface water discharge permitting system is administered under the Louisiana Pollutant Discharge Elimination System (LPDES) program.  LDEQ became a state delegated to administer the NPDES Program in August of 1996.  (Official LPDES Program Assumption Documents are available on the EPA Region 6 website.)

The Water Permits Division, within the Office of Environmental Services, consists of two LPDES Water Permitting Sections: Industrial Water Permits and Municipal & General Water Permits. Permitting responsibilities are distributed between the two sections based on facility type.    



The LPDES General Permits page contains copies of all general permits authorized under LAC 33:IX.2515.  General Permits are written to cover one or more categories or subcategories of discharges within a geographic area, which can range from a specific watershed to a broad area such as the entire state.
