Who Regulates Grease Traps in North Dakota
At the state level, North Dakota Department of Environmental Quality (DEQ), Water Quality Division (program page) oversees FOG (fats, oils, and grease) discharge; the governing rule is NDCC Chapter 61-28 (Control, Prevention, and Abatement of Pollution of Surface Waters); NDAC Ch. 33.1-16-01.1 (Pretreatment Regulations). Day-to-day enforcement — inspections, cleaning intervals, fines — usually happens through your city or county sewer utility's pretreatment program, which can set stricter rules than the state.
Hauler Licensing & Verification
North Dakota requires grease trap waste to be transported by licensed/registered haulers under North Dakota DEQ Septic Pumper Permit — covers grease trap waste; requires a passed exam, Secretary of State registration, $100 + $50/unit, renewed annually by March 1. (source) Before signing a contract, verify the hauler's registration on the official lookup — it takes two minutes and it's the single best protection against illegal-dumping liability landing on you.
City Programs in North Dakota
Cities run their own FOG programs and often set stricter rules than the state:
Fargo

Worth Knowing in North Dakota
North Dakota (which took over NDPDES pretreatment authority from EPA in 2005) regulates grease trap waste through its Septic Pumper Permit program — and its guidance explicitly treats grease trap waste as distinct from domestic septage. Cleaning frequency and manifest specifics are left to local POTWs like Fargo and Bismarck.
Frequently Asked Questions
How often must grease traps be cleaned in North Dakota?
No statewide interval — cleaning schedules are set by local POTW pretreatment programs (Fargo, Bismarck) rather than state rule. 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 Dakota?
NDCC §61-28-08 authorizes penalties and injunctions for violations of Chapter 61-28 (specific dollar amounts not published online). 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 Dakota?
No — use a licensed/registered hauler (North Dakota DEQ Septic Pumper Permit — covers grease trap waste; requires a passed exam, Secretary of State registration, $100 + $50/unit, renewed annually by March 1). If your hauler dumps illegally, the paper trail you kept is your protection. Verify registration on the official lookup linked above.
Do I need a permit for a grease trap in North Dakota?
In most North Dakota cities, yes — food service establishments must register with, or get a permit from, the local FOG / pretreatment program before discharging grease trap waste to the sewer. The exact permit and registration requirements vary by city; the major-city programs are listed above, and your local sewer authority has the specifics for your address.
