Grease Trap Requirements
Racine, WI
FOG compliance regulations for food service establishments in Racine, Wisconsin.
FOG Compliance in Racine, WI
Food service establishments in Racine operate under a combination of federal EPA pretreatment standards, Wisconsin 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 Racine, the rule is: Per manufacturer recommendation and use. This aligns with the 90-day US median enforced by most major cities. The city follows the Uniform Plumbing Code (UPC) for trap sizing and installation. Under Section 1014, which applies a fixture drainage load formula with a retention time factor, grease interceptors installed in Racine 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.
Racine 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.
Racine enforces the 25 percent rule: grease traps must be pumped before the combined FOG and settled solids reach 25 percent of the trap's total liquid depth. Inspectors measure the depth with a sludge judge or dipstick, typically at surprise visits. Exceeding the threshold at inspection triggers a notice of violation and mandatory emergency pump-out, regardless of the scheduled pumping cycle. 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 Racine Wastewater Utility (RWWU); delegated control authority under Wisconsin DNR, which handles permit issuance, inspections, and hauler licensing.
