Summary

The Louisiana Department of Environmental Quality regulates industrial facility air emissions and operations under La. R.S. 30:2001 et seq., but Louisiana has no comprehensive statewide industrial noise standard. Civil Code Article 667 provides universal nuisance protection for neighbors of industrial operations causing unreasonable noise.

No person shall operate or permit the operation of any sound amplification system which emanates unreasonably loud or excessive sound or noise which is likely to cause inconvenience or annoyance to persons of ordinary sensibilities, when both the following exist: (1) The sound amplification system is located in or on any motor vehicle on a public street, highway, or public park. (2) The sound or noise emanating from the sound amplification system is audible at a distance of greater than twenty-five feet which exceeds eighty-five decibels.

Full Breakdown

Louisiana lacks a numerical statewide industrial noise standard like those in some other states; LDEQ permitting under the Louisiana Environmental Quality Act (R.S. 30:2001 et seq.) focuses on air, water, and waste emissions but not specific decibel limits. Industrial noise is principally addressed through Civil Code Article 667-669 (vicinage obligations and nuisance) and through local zoning that designates compatible industrial districts. La. R.S. 30:2025 authorizes LDEQ enforcement of conditions placed on facility permits, which can include negotiated noise mitigation. Federal OSHA standards (29 CFR 1910.95) apply to occupational noise inside facilities. Neighbors can pursue civil nuisance actions even where a facility complies with permits.

Violations & Penalties

Civil nuisance remedies under C.C. 667 include abatement and damages. LDEQ permit violations can carry administrative penalties up to $32,500 per day under R.S. 30:2025.

Frequently Asked Questions

Does Louisiana DEQ regulate industrial noise levels?

Not by general numerical standard. LDEQ permits focus on air, water, and waste. Specific noise conditions may appear in facility permits, but Louisiana has no statewide industrial decibel cap like several other states.

Can I sue a Louisiana industrial plant for noise?

Yes. Louisiana Civil Code Articles 667-669 allow neighbors to seek abatement and damages for industrial operations causing unreasonable noise, even when the facility complies with state environmental permits.
