Every municipality depends on a reliable wastewater collection system. Yet every year, fats, oils, and grease (F.O.G.) continue to be one of the leading causes of sanitary sewer overflows (SSOs), sewer backups, increased maintenance costs, and unnecessary damage to public infrastructure. While grease interceptors and routine inspections are important tools, they are only part of the solution.
The most successful municipal F.O.G. programs are not built around enforcement alone. They are built around leadership, planning, education, accountability, and collaboration.
A F.O.G. program should protect more than pipes, it should protect public health, environmental quality, municipal resources, and the businesses that serve our communities.
At USFOGA, we believe the question isn’t whether a municipality needs a F.O.G. program. The question is whether that program has been designed to succeed.
Step 1: Define the Purpose of Your Program
Many municipalities begin developing a F.O.G. program after experiencing repeated sewer blockages or regulatory pressure following a sanitary sewer overflow. While these events often trigger action, they should not define the purpose of the program.
According to Byron Ross’ presentation on more than two decades of municipal F.O.G. program experience, successful programs focus on preventing F.O.G.-related sanitary sewer overflows, reducing sewer maintenance costs, minimizing odors and corrosion, and protecting every component of the publicly owned treatment works (POTW), not just the wastewater treatment plant.
An effective program should establish clear objectives such as:
- Protect wastewater infrastructure.
- Reduce emergency maintenance.
- Improve regulatory compliance.
- Support responsible food service establishments.
- Protect public health and local waterways.
When everyone understands why the program exists, decisions become easier and more consistent.
Step 2: Build a Strong Legal Foundation
No program can succeed without clear authority.
Federal regulations prohibit the discharge of materials that obstruct wastewater flow, but municipalities must establish local ordinances and policies that define how FOG will be managed within their jurisdiction. Byron Ross emphasizes that successful programs include sewer use ordinances or dedicated F.O.G. management policies that clearly establish legal authority, design standards, permitting requirements, inspection authority, and enforcement procedures.
A comprehensive ordinance should define:
- Who is regulated.
- Which facilities require grease control equipment.
- Design and installation standards.
- Maintenance requirements.
- Inspection authority.
- Recordkeeping expectations.
- Enforcement procedures.
- Appeals processes.
Clear expectations reduce confusion for municipalities, service providers, and food service establishments alike.
Step 3: Design the Program Before Inspecting the First Restaurant
One of the most common mistakes municipalities make is beginning inspections before designing the overall program.
EPA Region 4’s CMOM guidance identifies nine essential components of a successful F.O.G. program, and Byron Ross highlights these as the framework municipalities should follow:
- Legal Authority
- Plan Review and Design Standards
- Inspections
- Permitting and Control Mechanisms
- Enforcement
- Communication
- Performance Measures
- Public Education
- Information Management Systems
Each component supports the others. Removing one weakens the entire program.
Step 4: Bring Every Stakeholder to the Table
A municipal F.O.G. program is a team effort.
Wastewater utilities cannot manage grease alone.
Successful programs create ongoing communication among:
- Public Works
- Wastewater Operations
- Engineering
- Building and Code Officials
- Health Departments
- Fire Departments
- Food Service Establishments
- Grease Waste Haulers
- Plumbers
- Grease Interceptor Manufacturers
- Architects and Engineers
- Municipal Attorneys
Ross illustrates this as an interconnected communication network rather than a linear chain of command, reinforcing that effective programs depend on coordinated relationships across departments and industries.
When communication improves, compliance becomes easier, projects move faster, and infrastructure is better protected.
Step 5: Standardize Plan Review and Equipment Requirements
Every successful program begins long before the restaurant opens.
Plan review ensures grease control equipment is properly selected, sized, and installed before wastewater ever enters the collection system.
Poor design creates long-term operational problems.
As Ross notes, both undersized and oversized grease interceptors create risks. Undersized units allow grease to bypass treatment, while oversized units can increase retention times that contribute to hydrogen sulfide generation, corrosion, and odor problems.
Municipalities should establish consistent design criteria and coordinate closely with building departments, so grease control requirements become part of the permitting process, not an afterthought.
Step 6: Develop an Inspection Program That Educates
An inspection should never be viewed as a “gotcha.”
It should be an opportunity to improve understanding and encourage compliance.
Effective inspections evaluate far more than grease depth. Ross recommends standardized inspection protocols that consider safety, grease control equipment condition, downstream sewer observations, maintenance records, operational practices, and a review with the owner or manager before concluding the visit.
The best inspectors become trusted technical resources.
When operators understand why requirements exist, compliance often improves without enforcement.
Step 7: Use Enforcement Strategically
Enforcement remains an important part of every F.O.G. program, but it should not be the program.
Successful municipalities establish graduate enforcement procedures that begin with education and progress only when necessary.
Ross recommends documented enforcement response guides that define noncompliance categories, establish consistent responses, and create escalating corrective actions for repeat violations.
Consistency builds credibility.
Businesses are more likely to respect programs that apply standards fairly and transparently.
Step 8: Measure Performance, Not Activity
Many municipalities measure success by counting inspections completed.
That is an activity metric, not a performance metric.
Instead, municipalities should evaluate outcomes such as:
- Reduction in F.O.G.-related sanitary sewer overflows.
- Reduction in emergency sewer cleaning.
- Compliance rates.
- Repeat violations.
- Response times.
- Maintenance costs.
- Public complaints.
Ross emphasizes establishing measurable performance indicators and regularly evaluating whether they continue to reflect program effectiveness over time.
If a municipality performs hundreds of inspections but sewer blockages remain unchanged, the program should be reassessed.
Step 9: Invest in Public Education
Restaurants are only one source of F.O.G.
Residential grease disposal contributes significantly to sewer blockages in many communities.
Public education should become an ongoing effort rather than an annual campaign.
Effective outreach may include:
- Municipal websites.
- Social media.
- Utility bill inserts.
- School education.
- Community events.
- Printed materials.
- Restaurant training.
- Recycling information for used cooking oil.
Ross notes that sewer use policies often apply broadly to all users, making residential education an important complement to commercial compliance efforts.
Education reduces problems before enforcement is ever needed.
Step 10: Build a Program That Can Grow
As municipalities expand, so do their responsibilities.
F.O.G. programs generate significant amounts of information, including inspection reports, permits, photographs, maintenance records, enforcement actions, correspondence, sewer mapping, grease waste hauler documentation, and performance reporting. Ross stresses that effective information management is essential to maintaining consistency and supporting long-term program success.
Modern digital tools allow municipalities to improve scheduling, documentation, trend analysis, and communication while reducing administrative burdens.
A program that cannot effectively manage its data will eventually struggle to manage its infrastructure.
What This Means for Municipalities
An effective F.O.G. program reduces emergency maintenance, protects wastewater infrastructure, improves regulatory compliance, and provides measurable returns on investment. More importantly, it shifts municipal resources from reacting to sewer failures toward preventing them.
What This Means for Food Service Establishments
Restaurants, hotels, institutions, and food manufacturers benefit from clear expectations, consistent inspections, fewer plumbing emergencies, and stronger relationships with their local wastewater utility. A well-managed FOG program creates a more predictable operating environment and helps businesses avoid costly disruptions.
What This Means for Service Providers
Grease waste haulers, plumbers, interceptor manufacturers, engineers, and consultants play a critical role in program success. Standardized requirements, consistent communication, and shared best practices improve service quality, support compliance, and strengthen partnerships with municipal clients.
The USFOGA Perspective
The strongest F.O.G. programs are not defined by how many inspections they perform or how many violations they issue. They are defined by how effectively they protect infrastructure, support responsible businesses, and engage the people who share responsibility for the wastewater system.
A successful municipal F.O.G. program is built on more than regulations. It is built on planning, collaboration, education, accountability, and continuous improvement.
When municipalities, food service establishments, service providers, engineers, and educators work together toward a common purpose, everyone benefits, from the wastewater operator maintaining the collection system to the restaurant owner serving customers, and ultimately to the communities that depend on safe, reliable public infrastructure.
