TL;DR
Arkansas has no single grease trap board. Installation runs through an ADH-licensed plumber and a local plumbing permit. Pumping and hauling waste needs a separate ADH special waste transporter permit. Local installation permits usually cost $50 to $250. Confirm current fees and timelines with ADH and your city sewer authority before you buy a trap.
Which board actually regulates grease traps in Arkansas?
No agency in Arkansas is called the "Grease Trap Board." The work is split across at least three authorities, and figuring out which one you deal with first saves you weeks.
The Arkansas Department of Health (ADH) is the main state authority. ADH enforces plumbing standards under Ark. Code Ann. § 20-27-101 et seq., which covers plumbing installations including grease interceptors in commercial kitchens [1]. ADH also licenses plumbing contractors and inspects work across the state.
The discharge side belongs to the Arkansas Department of Energy and Environment, through its Division of Environmental Quality (ADEQ). Any grease-laden wastewater that reaches a surface water body or gets land-applied falls under ADEQ water quality permits [2].
Your local sewer authority or municipal public works department is the third layer, and often the one that controls your daily reality. Most Arkansas cities, including Little Rock, Fayetteville, and Fort Smith, run their own pretreatment programs under their NPDES permits. Those programs set interceptor sizing and pump-out schedules that can be stricter than the state baseline. Call your local sewer utility before you buy a trap.
For hauling, the ADH Solid Waste Management Program licenses grease trap pumpers as special waste transporters [3]. If you plan to pump and haul, that permit comes from ADH, not ADEQ.
Do you need a license for grease trap work in Arkansas?
Yes, and which license depends on exactly what you are doing.
Installing or modifying a grease interceptor is plumbing work. It has to be done by an ADH-licensed plumber. Arkansas uses a tiered structure: Apprentice, Journeyman, and Master. A Master Plumber license is required to pull the permit and supervise the install [4]. The Arkansas State Board of Plumbing Examiners (ASBPE) issues these licenses. The process means passing a written exam, documenting field hours, and paying a license fee. Confirm current fee amounts with ASBPE before applying [4].
Running a grease pumping or hauling business is different. ADH's Solid Waste Management Program requires you to register as a special waste transporter. The program covers non-hazardous special wastes, and grease trap waste is one of them [3]. You need a permit for each transport vehicle.
Food service operators generally do not need a personal plumbing license. You are still on the hook for making sure your interceptor was installed by a licensed contractor, sized to ADH plumbing code, and pumped on the schedule your local pretreatment authority sets. Skip the maintenance and you can face fines or lose your sewer permit.
Here is what trips people up. Some Arkansas cities also want a local business license or a city-level plumbing permit, even when your contractor already holds a state ADH license. Check with your city's permits office.
How much does grease trap work cost in Arkansas?
Cost breaks into three buckets: equipment, permits and licensing, and ongoing pump-out service. Anyone who quotes you one flat number for "grease trap cost" is hiding the parts that matter.
Equipment and installation. A small under-sink grease trap for a food truck or concession stand runs roughly $150 to $600 for the unit alone. A code-compliant in-ground interceptor for a full-service restaurant, which most Arkansas municipalities require for new commercial kitchens, runs $3,000 to $15,000 installed. The spread depends on capacity (usually 500 to 2,000 gallons for restaurant use) and site conditions like soil, access, and how far the tank sits from the kitchen drain. These are market estimates. Get at least three bids from ADH-licensed plumbers near you.
Permits. Local plumbing permit fees vary a lot across Arkansas. Most cities charge a base fee plus a per-fixture or per-dollar-of-work amount. A rough range from posted city schedules is $50 to $250 for a grease interceptor installation permit [5]. Confirm with your city's building office. Fees change, and some cities revised schedules in 2023 and 2024.
ADH plan review. New commercial facilities that need ADH plumbing plan review (generally new construction or a major renovation) may pay a plan review fee to ADH. Confirm current amounts with ADH directly.
Pump-out service. This one recurs. Arkansas restaurants typically pump every 30 to 90 days depending on volume and local rules. Market rates run roughly $150 to $400 per service for standard restaurant-size interceptors. Your actual quote depends on trap size, location, and hauler.
| Cost category | Typical Arkansas range | Notes |
|---|---|---|
| Under-sink trap (unit only) | $150 - $600 | Low-volume use only |
| In-ground interceptor (installed) | $3,000 - $15,000 | Full restaurant; depends on capacity and site |
| Local installation permit | $50 - $250 | Confirm with city permits office |
| Pump-out service (per visit) | $150 - $400 | Every 30-90 days; hauler must hold ADH transporter permit |
| Master Plumber license (ASBPE) | Confirm with ASBPE | Exam, field hours, and license fee required |
How long does grease trap permitting take in Arkansas?
It varies more than people expect, and most of the variance comes from which jurisdiction you are in.
For a local plumbing permit in a smaller Arkansas city or county, same-day or next-business-day issuance is common when the grease interceptor install is straightforward and the plans are complete. Larger cities, or projects that need plan review, run 2 to 6 weeks.
Projects that trigger ADH plan review (new commercial construction, additions past a square-footage threshold) go through ADH's Environmental Health Services branch, which reviews plumbing plans as part of the food service facility permitting process. ADH plan review for food service facilities generally takes 3 to 6 weeks after a complete application lands, though workload shifts that number [6]. Incomplete submissions reset the clock.
The ADH special waste transporter permit for grease pumping businesses has its own timeline. ADH's Solid Waste Management Program processes those applications. Confirm current processing times with ADH directly, because they are not consistently published.
An ASBPE plumbing license, starting from scratch as a contractor, takes far longer. Accumulating the required journeyman hours, scheduling and passing the exam, and getting your Master Plumber credential is measured in years, not weeks. Plan for that if you are entering the trade.
Practical advice: submit a complete application the first time. A missing site plan, drain line calculation, or proof of contractor licensure is the single most common reason applications stall.
What does Arkansas plumbing code say about grease interceptor sizing?
Arkansas adopts plumbing codes through ADH rule-making. Interceptor sizing is based on drainage flow rate (drainage fixture units, or DFU), the type of food service operation, and whether a hydromechanical (under-sink) or gravity (in-ground) interceptor fits the job. ASME A112.14.3 is a common reference standard for hydromechanical grease interceptor performance [10].
Hydromechanical interceptors are usually allowed only for low-flow spots, like a single sink in a small concession. Full-service restaurants almost always need a gravity interceptor. Many Arkansas municipalities set a minimum 1,000-gallon capacity in their local pretreatment ordinances regardless of what a DFU calculation suggests.
The "25% rule" shows up in ADH guidance and in local pretreatment programs: pump the interceptor once the combined grease and solids reach 25% of the working volume. Your local sewer authority can set a stricter trigger.
One detail worth checking. Some Arkansas cities have adopted the 2018 or 2021 International Plumbing Code (IPC) rather than the older Uniform Plumbing Code. That changes the interceptor sizing tables. Ask your local building department which edition is in effect before you spec your trap.
How does Arkansas's FOG (fats, oils, grease) pretreatment program work?
Arkansas cities that run publicly owned treatment works (POTWs) under an NPDES permit are required by EPA to run local pretreatment programs when they take significant industrial or commercial wastewater [7]. Restaurant grease is a primary target of those programs.
Under a typical Arkansas city FOG program, food service establishments (FSEs) have to register with the local sewer authority, install a correctly sized and approved interceptor, keep service records (pump-out manifests), and submit those records on the city's schedule. Little Rock's program, for example, requires FSEs to keep a log and produce it for inspection.
Manifests matter more than most operators think. When a licensed hauler pumps your trap, they should hand you a manifest or service receipt showing the date, the volume removed, and the disposal site. Keep those. Inspectors ask for them, and missing records can be treated as a violation even when the trap itself is clean.
If you are building your document system, GreaseTrapPath's Interceptor + Manifest Kit ($199, one-time) at /start covers the manifest templates and record structure most Arkansas pretreatment programs expect. Still, confirm your city's required format with your local sewer authority, because some cities use their own forms.
EPA's pretreatment regulations at 40 C.F.R. Part 403 set the federal floor [7]. Arkansas local programs can only go stricter, never looser.
What Arkansas agency handles complaints and enforcement?
Enforcement is layered, the same way the regulation is.
ADH can act against unlicensed plumbers or installations that break state plumbing code. Complaints about unlicensed contracting go to ADH or to the ASBPE depending on the nature of the complaint [4].
ADEQ handles complaints about illegal grease dumping, discharge violations, and unauthorized land application of grease trap waste [2]. If a hauler dumps grease trap waste somewhere other than an approved facility, that is an ADEQ matter.
Local sewer authorities enforce within their own pretreatment programs. Penalties for FSEs that violate local FOG rules usually start with a notice of violation, then move to fines, then to sewer service disconnection. Some Arkansas cities have set fines in the $500 to $2,500 per day range for repeat pretreatment violations. Confirm your city's penalty schedule with your local utility.
For haulers, ADH Solid Waste Management can suspend or revoke a transporter permit for violations.
How does Arkansas compare to neighboring states on grease trap regulation?
Arkansas sits in the middle of the pack regionally. It is more structured than some neighbors on licensing (the ASBPE requirement is real and enforced) but less prescriptive at the state level on pump-out frequency than Tennessee, which has published statewide FOG guidance with specific frequency recommendations.
Missouri, to the north, also runs a state plumbing board and has pushed harder toward mandatory municipal FOG ordinance adoption. Oklahoma, to the west, has its own Plumbing and AC/R Board with separate licensing.
The biggest practical difference for Arkansas operators is local variation. Because Arkansas leaves FOG program details mostly to municipalities, the rules in Fayetteville can differ from the rules in Texarkana. That is unlike California, which runs a more unified state pretreatment framework, or Florida, which codifies grease interceptor sizing in the Florida Building Code.
If your business runs in more than one state, see our guides on grease trap board in Alabama, grease trap board in Georgia, and grease trap board in Florida.
For states with very different structures, grease trap board in California and grease trap board in Illinois are worth reading too.
What paperwork do you actually need to operate a grease trap legally in Arkansas?
Here is the realistic document list for a food service establishment opening in Arkansas:
1. Contractor's ADH / ASBPE Master Plumber license for whoever pulls the permit and installs the trap. Get a copy for your files. 2. Local plumbing permit from your city or county for the interceptor installation. 3. ADH food service establishment permit (required before you open; ADH inspects the facility including the grease interceptor as part of this) [6]. 4. Local sewer authority FOG registration if your city runs a pretreatment program (most mid-size and larger Arkansas cities do). 5. Pump-out manifests / service records from your licensed hauler, kept on file. Your city likely sets a minimum retention period (often 3 years). 6. Interceptor sizing documentation showing your trap was sized to code, useful if you are ever inspected or challenged.
For grease hauling businesses, add:
- ADH Special Waste Transporter permit for each vehicle [3].
- Disposal facility approval documentation.
For licensed plumbing contractors:
- ASBPE Master Plumber license [4].
- Local contractor registration (many Arkansas cities require this separately).
None of this is exotic. The manifests are where operators most often fall short. Keep them organized and current.

Frequently asked questions
Do you need a license for grease trap installation in Arkansas?
Yes. Any grease interceptor installation must be performed by an Arkansas State Board of Plumbing Examiners (ASBPE)-licensed Master Plumber, who pulls the local permit. Food service operators do not need a personal plumbing license, but they must use a licensed contractor. Grease haulers need a separate ADH Special Waste Transporter permit. Confirm current license requirements with the ASBPE.
How much does grease trap installation cost in Arkansas?
A small under-sink unit costs roughly $150 to $600 for equipment alone. A full in-ground grease interceptor for a restaurant typically runs $3,000 to $15,000 installed, depending on tank size and site conditions. Local installation permits add $50 to $250. Pump-out service costs $150 to $400 per visit. Get multiple bids from ADH-licensed plumbers; prices vary by region and site.
How long does grease trap permitting take in Arkansas?
Simple local permits in smaller jurisdictions can be issued same-day or within one business day if plans are complete. Projects requiring ADH plan review for new commercial construction can take 3 to 6 weeks after a complete application is submitted. Incomplete applications reset the timeline. Confirm current processing times with ADH's Environmental Health Services and your local permits office.
Which Arkansas agency issues grease trap permits?
Local plumbing permits come from your city or county building department. ADH reviews plans for new food service establishments and issues the food service establishment permit. ADH's Solid Waste Management Program issues transporter permits for grease haulers. ADEQ handles water quality and discharge permits. There is no single "grease trap board" in Arkansas; jurisdiction depends on the type of work.
How often does a grease trap need to be pumped in Arkansas?
ADH guidance references the 25% rule: pump when combined grease and solids reach 25% of the interceptor's working volume. In practice, most Arkansas restaurants pump every 30 to 90 days. Your local sewer authority's pretreatment program may set a stricter schedule. Check with your city's FOG program coordinator for the requirement that applies to your specific facility.
Does Arkansas require manifests for grease trap pump-outs?
Most Arkansas cities with FOG pretreatment programs require food service establishments to keep pump-out manifests and produce them for inspection. The manifest should show the date, volume removed, hauler information, and disposal site. Retention periods are typically 3 years, but confirm your city's specific requirement. Missing manifests are a common violation even when the trap itself is maintained.
What is the Arkansas State Board of Plumbing Examiners?
The ASBPE is the state board that licenses plumbers in Arkansas, including those who install grease interceptors. It issues Apprentice, Journeyman, and Master Plumber licenses. A Master Plumber license is required to pull installation permits. You can verify contractor licenses through the ASBPE lookup. The board also handles complaints about unlicensed contracting.
Can a food service owner install their own grease trap in Arkansas?
No. Arkansas requires grease interceptor installation to be performed by an ASBPE-licensed plumber, and a Master Plumber must pull the permit. A food service owner who is not a licensed plumber cannot legally self-install. They can hire a licensed contractor and then manage their own maintenance records and pump-out scheduling once the interceptor is in place.
What size grease trap is required for a restaurant in Arkansas?
Sizing follows drainage fixture unit calculations under the plumbing code Arkansas has adopted (based on UPC or IPC depending on your municipality). Many Arkansas cities require a minimum 1,000-gallon in-ground interceptor for full-service restaurants regardless of DFU calculations. Ask your local building department which code edition applies and what local minimums are in effect before purchasing equipment.
Who licenses grease trap pumping companies in Arkansas?
ADH's Solid Waste Management Program licenses grease haulers as special waste transporters. A permit is required for each vehicle used to transport grease trap waste. ADEQ handles environmental compliance for disposal. If a hauler cannot show a current ADH transporter permit, do not use them; your local pretreatment program may hold you responsible for your hauler's compliance.
What happens if a restaurant in Arkansas skips grease trap maintenance?
Local sewer authorities can issue notices of violation, fines (often $500 to $2,500 per day for repeat violations in many Arkansas cities), and in serious cases, sewer service disconnection. ADH can act on plumbing code violations. Persistent FOG discharge can also pull in ADEQ. The practical risk of skipped maintenance is also a sewer backup in your own kitchen, which closes you faster than any inspector.
Does Arkansas have a state FOG control program?
Arkansas does not have a single statewide FOG control ordinance. Instead, municipalities with NPDES-permitted treatment works run their own pretreatment programs under EPA requirements at 40 C.F.R. Part 403. Larger Arkansas cities like Little Rock and Fayetteville have active FOG programs; smaller municipalities may have minimal requirements. Always check with your local sewer authority.
How do I verify a plumber's license in Arkansas before hiring them for grease trap work?
Use the ASBPE license lookup tool. Search by name or license number. Confirm the license is active, that it is a Master Plumber license (higher than Journeyman), and that it has not lapsed or been disciplined. Ask the contractor for their license number before signing any contract; a legitimate licensed plumber gives it to you immediately.
Is grease trap waste considered hazardous in Arkansas?
No. Grease trap waste is classified as a non-hazardous special waste in Arkansas, regulated under ADH's Solid Waste Management Program rather than ADEQ's hazardous waste rules. That said, disposal still requires an approved facility; illegal dumping of grease trap waste is an environmental violation under ADEQ jurisdiction and can result in significant penalties.
