Louisiana Septic Hauling Compliance Guide

Louisiana regulates septage hauling through the Department of Environmental Quality under LAC 33:IX, with an enforcement mechanism that puts receiving facilities at direct risk. Under Louisiana rules, only DEQ-authorized haulers may deliver septage to treatment or disposal sites. If a receiving facility accepts a load from an unauthorized hauler, that acceptance itself constitutes a permit violation for the facility — not just for the hauler. This creates strong downstream pressure on haulers to maintain current authorization.

Registration is per business with annual renewal through LDEQ. Manifests must document six fields: generator name, generator address, truck license plate number, gallons transported, date of transport, and disposal site. The vehicle plate requirement means LDEQ can trace loads back to specific trucks even though registration is at the business level.

Penalties under La. R.S. 30:2025 and LAC 33:I.1309 include both civil and criminal enforcement. Records should be retained for at least 5 years following the federal default.

Louisiana also stands apart on grease trap waste. LDEQ requires a separate registration for haulers transporting sewage sludge mixed with grease from food service facilities. That registration runs on a July 1 to June 30 fiscal year, and haulers must submit a yearly summary on Form 7362 by February 19. Laboratory testing of grease trap waste is required for hazardous characteristics before it can be mixed with other materials. This is a level of grease regulation most states do not approach.
