St. Louis Restaurant Grease Trap Requirements & Compliance Guide
Grease traps and interceptors are critical equipment in commercial kitchens, required by the City of St. Louis and State of Missouri to prevent fat, oil, and grease (FOG) from entering municipal sewer systems. Improper maintenance leads to costly violations, operational shutdowns, and environmental violations. Understanding local and state requirements helps restaurant operators avoid citations and maintain food safety standards.
St. Louis City Grease Trap Regulations
The City of St. Louis Department of Health requires all food service establishments to install and maintain grease traps or interceptors sized according to peak wastewater flow. The St. Louis City Health Code mandates that grease traps must have a minimum capacity of 40 pounds of grease retention and be inspected by the city at least twice per year. Restaurants must also maintain detailed maintenance logs documenting cleanings, pump-outs, and inspections. Non-compliance results in violations that can escalate to fines or temporary closure if not corrected within specified timeframes.
Missouri State and Federal FOG Requirements
Missouri Department of Natural Resources enforces FOG management under state water quality regulations, while the EPA's National Pretreatment Standards (40 CFR Part 403) set baseline federal requirements. Missouri state code requires grease trap pumping no less frequently than when the trap reaches 25% capacity—typically every 1-3 months depending on kitchen volume. The State of Missouri and St. Louis differ in inspection frequency and reporting; St. Louis requires city health department sign-off, while state inspections focus on wastewater discharge compliance. Food facilities must also have a current food service license and demonstrate FOG source control at the point of generation (drains, pre-rinse stations).
Maintenance Best Practices and Monitoring
Effective grease trap management includes daily sink strainers, regular scraping of cookware, and scheduling professional pump-outs before capacity limits are reached. Restaurant staff should maintain daily logs noting grease trap condition and any visible issues, which inspectors review during St. Louis Health Department visits. Real-time monitoring systems help restaurants track trap usage patterns and alert managers before violations occur, reducing the risk of sewage backups or penalties. Partnering with licensed FOG disposal contractors ensures compliant documentation and proper waste handling per Missouri and EPA standards.
