Grease Trap Requirements
Jackson, MS

FOG Compliance in Jackson, MS

Food service establishments in Jackson operate under a combination of federal EPA pretreatment standards, Mississippi state plumbing code, and city-level FOG ordinances. Together these rules determine how grease traps must be sized, how often they must be pumped, and what happens when a restaurant falls out of compliance.

Pumping frequency is the compliance rule restaurant owners interact with most often. In Jackson, the rule is: Interceptors: completely pumped every 90 days minimum. This aligns with the 90-day US median enforced by most major cities. The city follows the International Plumbing Code (IPC) for trap sizing and installation. Under Section 1003.3.4, which sizes traps by drainage fixture unit counts, grease interceptors installed in Jackson must meet minimum capacity thresholds based on the fixtures connected to them — 3-compartment sinks, dishwashers, pre-rinse stations, wok stoves, and floor drains on the cook line.

Jackson requires a dedicated FOG permit for any food service establishment generating fats, oils, and grease. The permit is separate from, and in addition to, the plumbing permit required at installation.

Periodic inspections of restaurants and commercial kitchens. Establishments must maintain pumping logs, hauler manifests, and inspection reports on-site — missing records is itself a violation in most enforcement actions. Enforcement authority rests with the City of Jackson Public Works Department, which handles permit issuance, inspections, and hauler licensing.
