Grease trap & interceptor cleaning in Bay St. Louis, MS
Bay St. Louis is the Hancock County seat, with restaurants in Old Town and along the beachfront. Hancock County has its own grease ordinance, separate from Harrison County's. Here's what it says, and how to get quotes.
A stricter baseline schedule than many kitchens expect
Restaurant owners who have worked in Harrison County are often used to thinking about a 90-day mark. Hancock County's ordinance sets a different baseline: 30 days for grease interceptors, unless the Authority grants an exception, with 90 days as the outer limit even then (details and source below). If you operate in Bay St. Louis:
- Budget for monthly service on an interceptor unless you have a written exception from the Authority.
- Keep five years of manifests. Store the manifest from every pump-out where you can find it during an inspection.
- Skip the additives. The ordinance prohibits putting surfactants, solvents, and emulsifiers, including enzymes and soap, into a grease interceptor. Ask your provider about any product before you use it.
- Measure, don't guess. The 25% wetted-height trigger in the ordinance means a busy kitchen may need service even sooner than 30 days.
Grease trap rules in Bay St. Louis: Hancock County Utility Authority
Bay St. Louis is in Hancock County. The Hancock County Utility Authority (which abbreviates itself "HANCUA" in its ordinance, not to be confused with the Harrison County "HCUA") adopted a Fats, Oils, and Grease Ordinance in November 2011. It applies to non-domestic users of the Authority's wastewater system, including restaurants, food processors, hospitals, hotels and motels, and nursing homes. Key points:
- 30-day baseline for interceptors. Grease interceptors must be completely evacuated at least every 30 days, or more often when 25% or more of the wetted height holds floating material, sediment, oils, or grease, when discharge limits are exceeded, or when there is a history of non-compliance.
- Exceptions, with a 90-day cap. An owner can ask in writing for a longer interval, granted case by case, but every interceptor must be fully evacuated, cleaned, and inspected at least once every 90 days.
- Manifests. Each pump-out must be accompanied by a manifest, and the generator keeps copies for five years.
- No additives. Surfactants, solvents, and emulsifiers (including enzymes, soap, diesel, kerosene, and terpene) may not be put into a grease interceptor.
- Penalties. The ordinance sets a schedule of civil penalties, starting with a written warning and rising with repeat violations within a two-year period, plus separate penalties if a generator causes a sewer line blockage.
Confirm with the Hancock County Utility Authority and the City of Bay St. Louis utility department how the ordinance applies to your address.
