Summary
Louisiana implements the federal NPDES stormwater program through the Department of Environmental Quality under La. R.S. 30:2074 and LAC Title 33. Construction sites disturbing one or more acres need an LPDES permit, regardless of local rules.
(4) To develop permitting procedures and to require and issue permits, variances, LPDES variances, licenses, or compliance schedules for all waste water discharges, discharges of waste, or sources of water pollution to the surface waters of the state, and to require of and issue LPDES permits to any person who prepares sewage sludge, applies sewage sludge to the land, or fires sewage sludge in a sewage sludge incinerator, or to the owner or operator of a sewage sludge surface disposal site and, when the secretary deems it advisable, to delegate the power to issue or deny such permits, variances, LPDES variances, licenses, or compliance schedules to the appropriate assistant secretary subject to his continuing oversight.
Full Breakdown
Under the Louisiana Pollutant Discharge Elimination System (LPDES), construction activities that disturb one acre or more, or are part of a larger common plan disturbing one acre, must obtain coverage under the LPDES Construction General Permit before earth-disturbing activity begins. Operators must prepare a Stormwater Pollution Prevention Plan (SWPPP), install best management practices for sediment and erosion control, conduct routine inspections, and file a Notice of Termination upon stabilization. Industrial facilities in regulated SIC categories require Multi-Sector General Permit coverage. LDEQ inspects sites and issues compliance orders. Local stormwater ordinances may add requirements but cannot waive LPDES coverage.
Violations & Penalties
Discharging without LPDES coverage, failing to maintain a SWPPP, or violating effluent limits can trigger LDEQ administrative orders and civil penalties up to $32,500 per day per violation under R.S. 30:2025.
