Grease Trap Requirements
Shepherdsville, KY

FOG Compliance in Shepherdsville, KY

Food service establishments in Shepherdsville operate under a combination of federal EPA pretreatment standards, Kentucky 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.

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 Shepherdsville 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. The local minimum trap size is: 500 gallons minimum (daily waste flow <= 6,000 gal); 1,000 gallons minimum (daily waste flow > 6,000 gal) per Kentucky state standards.

Shepherdsville requires a dedicated FOG permit for any food service establishment generating fats, oils, and grease. The annual permit fee is $1,000 interceptor line access fee; $300 waste hauler permit. The permit is separate from, and in addition to, the plumbing permit required at installation.

Inspection after installation by Water Quality staff. 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 Shepherdsville Wastewater Department, which handles permit issuance, inspections, and hauler licensing.
