Summary

Baton Rouge City-Parish Code Sec. 2:362 bars anyone from dumping pollutants into the municipal storm sewer system (MS4), covering both the city and the unincorporated parish. The Department of Public Works enforces limits on pH, oil and grease, silt and toxic substances entering storm drains that empty untreated into local waterways.

These county ordinances apply to unincorporated areas of East Baton Rouge Parish. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

No point source or non-point source shall discharge or cause to be discharged directly or indirectly any pollutant, contaminant or other waters which will or has the potential of causing damage to the stormwater transport system or the surface waters of the state ... In no case shall extractable oil and grease exceed DEQ limits within any discharge into a storm sewer system nor shall oil or greases from any source be disposed of within the storm sewer system.

Full Breakdown

Chapter 8 of Title 2 regulates every discharge into the City-Parish's municipal separate storm sewer system, called the MS4. Sec. 0, solids that could clog a storm sewer, or toxic pollutants that would harm receiving waters. Subsection (a)(3) specifically bars oil and grease from any source in excess of Department of Environmental Quality (DEQ) limits, and forbids disposing of oil or grease in the storm system at all. Subsection (a)(9) makes clear that erosion-control and floodplain ordinances are never exempted from this chapter, and failure to comply with those local ordinances is enforced through the remedies in Chapter 8 itself.

Liquid waste haulers are separately barred from dumping septic, grease-trap or carpet-cleaning waste into the storm system under subsection (b). Industrial and treatment-facility discharges require a Louisiana DEQ water discharge permit and an NPDES permit filed with the Director of Public Works before any discharge begins (subsection (c)), and state institutions including LSU, Southern University and the Louisiana DOTD are covered as co-permittees under the City-Parish's own MS4 permit (subsection (i)). The Director, under Sec. 0. Dischargers must supply a stormwater management plan on request showing they use the best available control technology to keep pollutants out of the storm sewer.

Violations & Fines

Under Sec. 2:369(c), a civil penalty of up to $1,000.00 per day, per violation applies to anyone who discharges in violation of the chapter or a permit condition, plus the City-Parish's attorney's fees and court costs. Willful or knowing violations, including falsifying monitoring records or discharging without a required DEQ/EPA permit, are criminal misdemeanors under Sec. 2:369(d) punishable by a fine of up to $1,000.00, up to six months imprisonment, or both. The Director of Public Works may also seek injunctive relief in court to stop an ongoing discharge under Sec. 2:369(b).

Frequently Asked Questions

Can I hose oil or grease from my driveway into a storm drain in East Baton Rouge Parish?
No. Sec. 2:362(a)(3) prohibits disposing of oil or grease into the storm sewer system from any source, and caps extractable oil and grease at 15.0 mg/l on a 30-day average under Sec. 2:363(a)(1). The Department of Public Works can pursue a civil penalty of up to $1,000 per day for a violation.
Does a DEQ or NPDES permit satisfy the parish's stormwater rules?
Yes. Sec. 2:366(a) states that a Louisiana DEQ discharge permit or an NPDES permit serves as the City-Parish discharge permit, but the discharger must still file a copy with the Director of Public Works before discharge begins.
What happens if I falsify a stormwater monitoring report?
Sec. 2:369(d)(1)-(2) makes knowingly falsifying a monitoring device, application, or report a criminal offense, punishable upon conviction by a fine of up to $1,000, up to six months in jail, or both, in addition to any civil penalty.
