Grease Trap Requirements

FOG Compliance in Greenville, SC

Food service establishments in Greenville operate under a combination of federal EPA pretreatment standards, South Carolina 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 Greenville, the rule is: annual. This is more lenient than the US median, typical of jurisdictions with lower-volume food service sectors. 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 Greenville 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.
