Pennsylvania Grease Trap Regulations
FOG Compliance Overview
Pennsylvania follows the International Plumbing Code (IPC) as its base plumbing code. The IPC requires grease interceptors for food service establishments and references sizing based on fixture unit counts and flow rates. The state's regulatory authority is the Pennsylvania Department of Environmental Protection (DEP).
With approximately 27,120 food service establishments statewide, Pennsylvania has significant FOG compliance needs. Individual cities and municipalities may adopt additional local ordinances that go beyond the state plumbing code, including stricter pumping schedules, permit requirements, and enforcement penalties. Of the 6 cities we cover, 5 require a dedicated FOG permit. 5 cities enforce the 25% rule for grease trap pumping.
