Avoiding FOG Violations in Miami: Grease Trap Cleaning Schedules That Pass Inspections

Originally published: January 2026 | Reviewed by Grease Pros

Miami restaurants operate under Miami-Dade County’s Fats, Oils, and Grease (FOG) Control Program because unmanaged grease can block sewer infrastructure and trigger enforcement actions. 

A “safe” grease trap cleaning schedule in Miami is not a generic 90-day calendar reminder. 

A defensible schedule starts with the installed device type, stays within the FOG capacity limit, and maintains inspection-ready records on-site.

Miami Grease Trap Cleaning Schedule

Miami restaurants should base grease interceptor pump-out intervals on Miami-Dade County Code § 24-42.6 (Fats, Oils and Grease Control Program), which specifies cleaning requirements by device type and sets compliance expectations.

Miami-Dade County Code sets baseline cleaning intervals by device type:

• Automatic hydromechanical grease interceptors: monthly cleaning by a permitted liquid waste transporter; daily emptying of strainers/storage receptacles by the operator; malfunction can trigger daily cleaning until repair.
• Manual hydromechanical grease interceptors: monthly cleaning by a permitted liquid waste transporter (or more frequently when needed).
• Gravity grease interceptors: every 60 days, cleaning by a permitted liquid waste transporter (or more frequently when needed).
• Gravity interceptors with a functional monitoring device: interval not to exceed 180 days, subject to the same capacity and standard constraints.

Miami-Dade County Code also requires each FOG generator to keep records on-site for at least 3 years and make them available upon request; off-site records do not substitute.

Restaurants seeking a code-aligned pump-out cadence can use Grease Trap Cleaning Service to establish a consistent schedule and reduce inspection-day risk.

Why Miami FOG Violations Happen (Schedule Failures, Not “One Bad Day”)

Miami FOG violations usually stem from incorrect cleaning cadence, missing manifests, insufficient staff training documentation, and poor storage-area controls. 

A compliant program uses device-specific baselines, capacity-based triggers, daily storage checks, and onsite records that inspectors can review in minutes.

1. Wrong baseline interval (monthly vs 60-day vs monitored 180-day) because the device type was misunderstood or undocumented.
   
2. No trigger logic for busy weeks (tourist season, events, promotions, expanded fryer hours) that accelerate grease loading.
   
3. Recordkeeping gaps (missing manifests, missing staff training documentation, missing service-call documentation) during inspection.
   
4. Storage area noncompliance (overfilled containers, spill cleanup done incorrectly, lids not maintained/locked), which is explicitly addressed in the Miami-Dade code.
   A schedule that prevents violations functions like an SOP: a baseline cadence, weekly checks, and documented proof.

Grease Trap vs. Grease Interceptor) (Miami schedule depends on category)

A “grease trap” typically refers to a hydromechanical grease interceptor, while a gravity grease interceptor is a larger, retention-based unit. 

Miami-Dade assigns different baseline cleaning intervals to each device type, so identifying the installed system prevents scheduling errors that can lead to violations.

Grease trap / hydromechanical grease interceptor (HGI)

Hydromechanical units are typically smaller, often indoor, and rely on flow control and internal baffles/media. Miami-Dade Code assigns monthly cleaning as the baseline for both automatic and manual hydromechanical grease interceptors.

Gravity grease interceptor (GGI)

Gravity interceptors are larger, often in-ground, and rely on retention time and volume to separate FOG and solids. 

Miami-Dade Code sets a 60-day cleaning baseline, with a conditional extension to 180 days when a functional interceptor monitoring device is present.

Practical takeaway: A “one-size schedule” creates compliance risk in Miami because Miami-Dade code does not treat all devices the same.

What Inspectors Measure (Capacity Limits, Storage Rules, And Documentation)

Miami inspections focus on three controllables:  grease and solids accumulation relative to capacity limits; compliance in grease storage areas (no overfill, absorbent-only spill cleanup, secured lids)

and onsite documentation, such as manifests, service calls, repairs, and training records, is retained for 3 years.

Miami-Dade compliance teams refer to the Miami-Dade FOG Control Program Guidance Manual for program definitions and operational guidance to support capacity-based scheduling and inspection readiness.

The FOG capacity limit (the 25% concept)

Miami-Dade’s guidance defines “FOG Capacity Limit” as the combined FOG and solids depth equal to 25% of the design hydraulic depth (or an equivalent third-party rated capacity method).

 A cleaning schedule that ignores capacity checks invites violations during high-volume periods.

For the Miami-specific enforcement context and the 25% capacity explanation, reference the Miami-Dade FOG & GDO Compliance Guide as the operational companion to Miami-Dade County requirements.

The grease storage area rules that most restaurants overlook

Miami-Dade County Code requires operational controls for yellow/brown grease storage areas:

• Daily visual inspection
• No overfilling; empty containers before 90% capacity
• Spill cleanup using absorbent materials.
• No wet cleanup methods for spills
• Lids are maintained to prevent rainwater inflow and locked to prevent vandalism.m

Many “FOG problems” in Miami begin as storage problems: overflow, unsecured lids, or sloppy spill handling that escalate into documented compliance issues.

The permitted hauler requirement (the compliance backbone)

Miami-Dade FOG training materials instruct operators to clean interceptors at the frequency established in the facility’s permit and to use a DERM-permitted hauler for full evacuation. 

Even when staff skim or remove material between services, the compliant backbone remains permitted hauling and proper manifests.

Miami-Dade Cleaning Schedule By Device Type 

Device category	Miami-Dade baseline cleaning interval	Who performs the cleaning	“Accelerate the schedule” triggers	Special notes
Automatic hydromechanical grease interceptor	Monthly (or more frequently to avoid exceedance)	Permitted liquid waste transporter	High fryer hours, odors/slow drains, approaching capacity limit	If automatic components malfunction: operate/report as manual and clean daily until repaired; sanitary nuisance abatement timelines apply
Manual hydromechanical grease interceptor	Monthly (or more frequently as needed)	Permitted liquid waste transporter	Rapid accumulation, backups, peak seasons, and capacity threshold risk	Alternative frequencies up to 90 days require approval via engineering analysis/field study
Gravity grease interceptor (standard)	Every 60 days (or more frequently as needed)	Permitted liquid waste transporter	Fryer-heavy menu, event weeks, increased seating, recurring downstream issues	Treat 60 days as baseline, not a ceiling—volume can require faster service
Gravity grease interceptor with monitoring device	Interval not to exceed 180 days, and not exceeding limits	Permitted liquid waste transporter	Monitoring failure, capacity/standard risk, nuisance conditions	Monitoring does not eliminate the need for records and manifests

Build A Miami-Proof Schedule (Baseline, Triggers, And Accountability)

A Miami-proof grease trap schedule combines the code-based baseline interval with volume triggers that force earlier pump-outs during peak weeks. 

Assign a named owner, document the installed device, add weekly checks, and treat odors, slow drains, and rapid accumulation as signals to accelerate service.

Step 1 — Document the installed system 

Create a one-page “FOG Device Profile” with:

• Device category (hydromechanical manual/automatic vs gravity)
• Location and access points
• Who owns inspections (title/role)
• Service vendor and service contact method
• Baseline interval from the table above

This reduces schedule failure during staff turnover.

Step 2 — Add trigger rules for Miami’s real operating conditions

Miami volume changes are predictable: weekends, seasonal tourism, major local events, promotions, and menu shifts. Add at least two triggers:

• Capacity trigger: schedule service sooner when grease/solids approach the capacity limit (as defined in the guidance at 25%).
• Operational trigger: schedule service sooner after extended fryer hours, a spike in covers, or any nuisance indicators (slow drains, odors, backups).

Step 3 — Lock in storage compliance as a daily habit

The Miami-Dade County Code outlines daily storage inspections and pre-90% emptying. Treat that as a daily close-out task. 

Storage area compliance protects safety and reduces the risk of an inspector finding visible, documentable noncompliance.

Recordkeeping Is The Fastest Path To “No-Issue” Inspections

Miami-Dade requires FOG generators to retain onsite records for at least 3 years, including manifests, maintenance and repair records, service call records, and training records. 

A binder system with a device profile, chronological manifests, and training logs reduces inspection friction and prevents avoidable citations.

Build an inspection binder that answers questions in under 60 seconds

A strong binder has:

• A “FOG Device Profile” one-pager on top
• The last 12 months of manifests in chronological order
• A log of repairs/service calls related to FOG or drainage
• Staff training sign-in sheets and quarterly refresh notes
• A storage-area daily checklist sheet

Miami-Dade onsite compliance binder 

Record type	What it proves	Minimum cadence	Owner	Miami-Dade retention requirement
FOG control device cleaning + manifests	Permitted transporter performed cleaning; service matches schedule	Every service	GM / Facilities	On-site≥ 3 years
Scheduled/unscheduled drain and sewer service calls	Response to drainage issues: prevents repeat incidents	As needed	Facilities	On-site≥ 3 years
Repairs caused by food/FOG accumulation	Corrective action taken	As needed	Facilities	On-site≥ 3 years
Staff training records	New employee orientation + quarterly refresh training occurred	On hire + quarterly	GM / Training Lead	On-site≥ 3 years
Storage area daily inspection notes	Containers emptied to less than 90%; spill cleanup followed absorbent/no-wet rules.	Daily	Shift lead	Best practice (supports code compliance)

Common Miami Mistakes That Increase Violation Risk

Common drivers of violations include using the wrong interval (defaulting to 90 days), ignoring storage area rules (e.g., emptying before reaching 90% capacity), and failing to document quarterly employee training. 

Fryer-heavy kitchens should align staff training with NFPA guidance on Class K fire extinguishers, as Class K equipment is designed to address the fire hazards posed by cooking oil and animal fat common in commercial kitchens.

Mistake 1 — Treating “90 days” as the default schedule

Some industry materials and vendor content reference 90-day intervals, but the Miami-Dade County Code sets monthly and 60-day baselines for common device categories. 

Miami-Dade code permits certain alternative frequencies (e.g., hydromechanical alternatives) only with approval and supporting analysis/field study. Treat 90 days as “possible with approval,” not “automatic compliance.”

Mistake 2 — Using the wrong cleanup method in storage areas

Miami-Dade code specifies absorbent spill cleanup and prohibits wet cleanup methods for yellow/brown grease storage spills. This is one of the easiest compliance wins because it is fully controllable with training and a staged spill kit.

Mistake 3 — Missing quarterly training documentation

Miami-Dade code requires orientation training for new employees and quarterly training for existing employees, with records maintained on-site. 

Restaurants often provide verbal training but fail to document it. Documentation is what matters during inspection.

Frequently Asked Questions 

How Often Should Grease Traps Be Cleaned In Miami-Dade County?

Miami-Dade County sets baseline pump-out rules by device type: hydromechanical grease interceptors require monthly cleaning, while gravity grease interceptors require cleaning every 60 days. Monitored gravity interceptors may be extended for up to 180 days, depending on conditions.

What Is The “25% Rule” For Grease Interceptors, And Why Does It Matter In Miami?

The “25% rule” treats a grease interceptor as “due” when floating FOG plus settled solids reach 25% of the device’s hydraulic depth/volume. Miami-Dade uses FOG capacity limits to trigger more frequent cleaning to avoid exceedances.

Who Is Allowed To Pump Out A Grease Trap Or Grease Interceptor In Miami?

Miami-Dade County Code requires grease interceptor cleaning to be performed by a liquid waste transporter permitted by the Department. Restaurants should keep transporter manifests onsite as proof of compliant pump-out and disposal practices during inspections.

What Records Do Miami Restaurants Need To Keep To Avoid FOG Violations?

Miami-Dade compliance focuses on documentation as much as cleaning frequency. Miami-Dade guidance and industry compliance checklists emphasize retaining pump-out manifests and maintaining on-site records so inspectors can verify service dates, volumes, and permitted hauler details during inspections.

How Long Should FOG Manifests And Compliance Logs Be Kept Onsite In Miami-Dade?

Miami-Dade guidance commonly states inspectors can request up to three years of records during an inspection. A Miami restaurant should maintain an on-site binder (and optional digital backup) containing manifests, service calls, repairs, and training documentation.

Do Miami Restaurants Need A FOG Discharge Control Operating Permit?

Miami-Dade categorizes restaurants as FOG generators and requires FOG Discharge Control operating permits. Miami-Dade permits are renewed annually and are non-transferable, so new owners must secure a new permit and maintain compliance records throughout the year.

What Practices Reduce Grease Trap Fill Rate And Help Prevent Violations?

A violation-resistant kitchen program combines pump-outs with source control: scrape plates, dry-wipe pans, keep fryer oil out of drains, and control spill cleanup. Miami-Dade code-based schedules also require earlier servicing when conditions are expected to exceed capacity limits.
