Current Grease Trap Compliance Trends

  • The 25% rule is the standard trigger for cleaning

    When combined floating grease and settled solids reach 25% of an interceptor's liquid capacity, it must be pumped — high-volume restaurants often need monthly service to stay ahead of that threshold, while smaller cafes may only need quarterly. (Industry FOG compliance guides, 2026)

  • Non-compliance penalties can be severe and cumulative

    Maximum penalties can reach $10,000 per day per violation in some jurisdictions, and most FOG ordinances require at least three years of service records be kept and available for inspection — documentation matters as much as the cleaning itself. (Industry FOG compliance guides, 2026)
