Permit authority, fine schedule, BMP requirements, and enforcement examples for commercial pressure washing in New Orleans. Your paper trail starts with a PAR.
Two penalty tracks stack simultaneously. Operating without documented BMPs exposes you to both.
| Enforcing Authority | Permit / Authority | Per-Violation Daily Fine | Notes |
|---|---|---|---|
| Louisiana Department of Environmental Quality (LDEQ) / Sewerage and Water Board | LPDES General Permit LAR040000 (Louisiana equivalent of NPDES) | $25,000/day | State civil penalty; accrues daily until corrected and documented |
| U.S. EPA (CWA §309) | Clean Water Act §309 | $48,762–$56,460/day | Federal civil penalty floor; applies simultaneously with state penalties. 2025 CPI-adjusted. |
| Combined 30-day exposure | — | $750,000+ (state only) | One uncontained job, no PAR. 30 days × state daily penalty before settlement. |
Note: Municipal penalties may apply separately under local ordinances. Total exposure frequently exceeds state-level figures when federal and municipal tracks stack.
These are the documented steps that demonstrate compliance with Louisiana Department of Environmental Quality (LDEQ) / Sewerage and Water Board requirements under LPDES General Permit LAR040000 (Louisiana equivalent of NPDES). Each step is independently verifiable by an inspector — missing one is sufficient for a Notice of Violation.
Post-Katrina stormwater system overhaul (2006–2016) placed Sewerage and Water Board under federal oversight. LDEQ actively enforces LPDES violations; pressure-wash runoff reaching catch basins goes directly to pump stations discharging to Lake Pontchartrain.
The Lake Pontchartrain / Mississippi River watershed is actively monitored. Stucco and wood (New Orleans shotgun houses) — New Orleans' subtropical climate (humidity 80%+) produces relentless mold on historic wood and stucco. French Quarter and Garden District structures require soft-wash techniques; high-pressure washing can damage plaster and introduce debris into the 18th-century drainage network. Hurricane season (June–Nov) is peak surface contamination season AND peak enforcement scrutiny.
Enforcement risk in New Orleans is year-round — not seasonal. Inspectors respond to complaints, conduct dry-weather outfall inspections, and follow up on spill reports from adjacent property owners. The most common NOV trigger is visible runoff reaching a curb cut or storm drain inlet — something that can be photographed by a neighbor and reported within minutes of a wash job starting.
Every New Orleans job documented, signed, and delivered as a certified Pressure Washing Activity Record. Your paper trail in case Louisiana Department of Environmental Quality (LDEQ) / Sewerage and Water Board comes calling.
Get Certified PAR — $99 →State penalties under Louisiana Department of Environmental Quality (LDEQ) / Sewerage and Water Board (Permit LPDES General Permit LAR040000 (Louisiana equivalent of NPDES)) reach $25,000/day per violation per day. The EPA federal floor adds another $48,762–$56,460/day simultaneously under Clean Water Act §309. Both tracks accrue daily until the violation is corrected and documented.
You don't need a standalone permit as a contractor — but the property's MS4 permit (LPDES General Permit LAR040000 (Louisiana equivalent of NPDES)) governs all stormwater discharge on-site. If your wash water reaches the storm drain without containment and documentation, you and the property owner are both exposed. BMP compliance demonstrated by a PAR is your protection.
A PAR (Pressure Washing Activity Record) documents the chemicals used, surface type, water recovery method, and disposal pathway for each commercial wash job. In New Orleans, it serves as your contemporaneous paper trail demonstrating BMP compliance with Louisiana Department of Environmental Quality (LDEQ) / Sewerage and Water Board requirements. Inspectors cannot challenge a properly completed PAR — it demonstrates intent and methodology, the two primary factors in settlement negotiations.
Pressure washing runoff in New Orleans drains to the Lake Pontchartrain / Mississippi River / Bayou St. John watershed. This system is actively monitored by Louisiana Department of Environmental Quality (LDEQ) / Sewerage and Water Board under LPDES General Permit LAR040000 (Louisiana equivalent of NPDES). Discharges that reach this waterway — even through intermediary storm drains — constitute a violation.
Core BMPs required by Louisiana Department of Environmental Quality (LDEQ) / Sewerage and Water Board: (1) pre-job site assessment with all storm drain inlets identified, (2) chemical log with SDS documentation, (3) water containment system deployed before washing begins, (4) pH testing of rinse water before disposal, (5) disposal to sanitary sewer only, (6) GPS-tagged pre/post photos, and (7) signed PAR filed for each job.
