Who Regulates Grease Traps in North Carolina

At the state level, NC Division of Waste Management, Solid Waste Section — Septage Program (NC DEQ) (program page) oversees FOG (fats, oils, and grease) discharge; the governing rule is Septage Management Rules, 15A NCAC 13B .0800–.0846; N.C.G.S. §130A-291.3.

Hauler Licensing & Verification

Worth Knowing in North Carolina

Charlotte Water's FlowFree platform takes maintenance records digitally.

Frequently Asked Questions

No statewide numeric interval — local pretreatment programs set schedules around the 25%-of-capacity standard. Charlotte requires under-sink units cleaned at minimum every 30 days; Raleigh applies the 25% threshold (typically every 30–90 days). Your city's FOG program may require more frequent service — and regardless of the legal interval, clean before fats, oils, and grease reach 25% of trap capacity.

What are the penalties for grease trap violations in North Carolina?

Set locally — first violations typically start around $250 with repeat violations reaching $1,000+, permit suspension, or shutdown orders. State-level civil penalties for pretreatment violations are authorized under N.C.G.S. §143-215.6A. Enforcement is usually municipal, so your city's fine schedule controls — the fastest way to stay off it is a maintained cleaning schedule and complete records.

Can anyone pump my grease trap in North Carolina?

No — use a licensed/registered hauler (Septage Management Firm Permit from NC DEQ — required for any firm that pumps, transports, stores, treats, or disposes of grease from interceptors or traps; trucks display an NCS permit number). If your hauler dumps illegally, the paper trail you kept is your protection. Verify registration on the official lookup linked above.
