Grease Trap Maintenance Inspection Checklist [FREE PDF]

Grease traps and interceptors are critical wastewater pretreatment devices required by local municipal sewer authorities under the EPA's Clean Water Act pretreatment program (40 CFR 403) to prevent fats, oils, and grease (FOG) from clogging sewer lines and causing sanitary sewer overflows. The FDA Food Code 2022 and state health department codes require grease interceptors to be properly maintained to prevent cross-contamination, odor generation, and pest attraction in food service environments.

Industry: Food Service
Frequency: Monthly
Estimated Time: 20-35 minutes
Role: Kitchen Supervisor
Total Items: 35
Compliance: FDA Food Code 2022 Section 5-402.13 - Grease Traps, EPA 40 CFR 403 - General Pretreatment Regulations, OSHA 29 CFR 1910.141 - Sanitation Standards, State Health Department Code - FOG Control Program, HACCP 21 CFR 120.8 - Sanitation Monitoring Records

Grease Trap Identification & Setup

Confirm the type, size, and installation details of the grease trap or interceptor being inspected.

Is the grease trap type correctly identified as an indoor trap or outdoor interceptor?
What is the rated capacity of the grease trap in gallons?
Is the grease trap located in an area that is accessible for inspection and pump-out service?
Are all fixtures and drains connected to the grease trap as required by the facility permit?
Is the grease trap manufacturer nameplate or ID tag visible and legible?

Physical Condition & Structural Integrity

Inspect the grease trap housing, lid, baffles, and inlet/outlet connections for physical damage and proper condition.

Is the grease trap lid or cover intact, properly seated, and free of cracks or damage?
Is the trap housing (walls, floor, and ceiling) free of cracks, corrosion, or structural defects?
Are inlet and outlet baffles or tees present, intact, and correctly installed?
Are inlet and outlet pipes free of visible blockages, cracks, or improper connections?
Is a photo of the open grease trap interior captured for the inspection record?

Grease Cap & Solids Accumulation Measurement

Measure and record the depth of the floating grease layer and settled solids to determine pump-out necessity.

What is the measured depth of the floating grease cap (FOG layer) in inches?
What is the measured depth of settled solids at the bottom of the trap in inches?
What is the total liquid depth of the grease trap in inches?
Does the combined grease and solids accumulation exceed 25% of the trap's working depth?
Is the trap water clear or showing signs of grease bypass (milky or discolored outlet flow)?

Odor Control & Sanitation

Evaluate odor conditions, pest evidence, and overall sanitation of the grease trap area.

Is the grease trap area free of excessive odors detectable in the kitchen or adjacent areas?
Is the area surrounding the grease trap free of grease spills, standing water, or FOG residue?
Is there any evidence of pest activity (droppings, tracks, nesting) near the grease trap?
Are biological additives or enzyme treatments being used in the trap in compliance with local sewer authority rules?
Is the area around the grease trap clean and free of food debris or waste?

Flow Rate & System Performance

Assess whether the grease trap is functioning at its designed flow rate and effectively separating grease from wastewater.

Is water flowing freely through the trap without backing up into connected fixtures?
Is the flow control fitting or flow restrictor (if present) intact and unmodified?
Is there any evidence of short-circuiting (water flowing directly from inlet to outlet without separation)?
For Automatic Grease Removal Units (AGRU): Is the skimming mechanism operating correctly?

Pump-Out Service & Waste Disposal Records

Review pump-out frequency, waste hauler documentation, and manifest records for regulatory compliance.

Is the pump-out frequency compliant with the local sewer authority's minimum required schedule?
Is the most recent waste hauler manifest or pump-out receipt available on-site?
Was the grease trap fully pumped ('pump and haul' method) rather than just the floating layer removed?
Is the waste hauler licensed by the state environmental agency for FOG waste transport and disposal?
Has the grease trap log book been updated with today's inspection results?

Corrective Actions & Inspector Sign-Off

Document any deficiencies identified, required corrective actions, and obtain management acknowledgment.

Were any deficiencies or non-compliant conditions identified during this inspection?
Please list all deficiencies, their severity, and the corrective action required?
Has an immediate pump-out been scheduled if accumulation exceeded 25% of working depth?
What is the target completion date for all identified corrective actions?
Has the Kitchen Supervisor reviewed, approved, and acknowledged this inspection report?
Is a final photo of the closed and secured grease trap attached to close out this inspection?
