Grease Trap Requirements
Newark, NJ
FOG compliance regulations for food service establishments in Newark, New Jersey.
FOG Compliance in Newark, NJ
Food service establishments in Newark operate under a combination of federal EPA pretreatment standards, New Jersey 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 Newark, the rule is: When storage reaches 75% capacity (per NJ state rule). 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 Newark 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: 750 gallons minimum per NJ Admin Code 7:9A-8.1.
Newark requires a dedicated FOG permit for any food service establishment generating fats, oils, and grease. The annual permit fee is Health Certificate required; contact City of Newark Division of Licensing at (973) 733-4311. The permit is separate from, and in addition to, the plumbing permit required at installation. Violations carry maximum penalties of Non-compliance may result in mandatory retrofits or permit suspension . Fines typically escalate with repeat violations, and severe discharges that cause sanitary sewer overflows can trigger federal Clean Water Act penalties layered on top of local fines.
Weekly self-inspections required; municipal inspections periodic. 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 Newark Dept of Health and Community Wellness; NJ DEP, which handles permit issuance, inspections, and hauler licensing.
