Salt Lake City Grease Trap Compliance Checklist for Restaurants

Salt Lake City Grease Trap Installation & Capacity Requirements

The Utah Department of Environmental Quality and Salt Lake City Health Department require all food service establishments to install properly sized grease traps or interceptors based on flow rate and menu type. Sizing calculations must follow the Utah Administrative Code R309-250, which bases capacity on fixture drain lines, water temperature, and peak usage hours. Your grease trap must be located in an accessible area for regular cleaning and pumping, typically exterior or in a dedicated room—never under the dining area or in customer-facing spaces. Documentation of installation by a licensed plumber and proof of capacity sizing should be maintained and available during inspections.

Maintenance, Cleaning & Inspection Checklist Items

Establish a documented maintenance schedule requiring pumping every 30–90 days depending on usage volume; high-volume establishments may need more frequent service. Daily checks should include monitoring water level, checking for visible blockages, and ensuring baffles are intact and functioning. Monthly inspections should verify that inlet and outlet pipes are clear, the lid seals properly, and there are no cracks or leaks in the tank structure. Keep records of all service calls, pumping dates, and the contractor's certifications—Salt Lake City inspectors will request these logs. Ensure your pumping contractor is licensed and disposes of waste at an approved facility; failure to use certified disposal violates both Utah environmental regulations and EPA standards.

Common Violations & How to Avoid Them

The most cited grease trap violations in Salt Lake City include undersized traps (leading to overflow into municipal sewers), improper cleaning intervals (resulting in blockages and backup), and lack of maintenance records during inspection. Avoid pouring cooking oils directly down drains, using chemical drain cleaners (which can damage the trap), or allowing grease accumulation to exceed 25% of tank depth. Never bypass, obstruct, or alter the grease trap system—inspectors conduct camera line inspections to detect illegal modifications. Failing to pump before the tank reaches capacity can trigger fines from $500–$2,500 and orders for immediate corrective action; establishments with repeat violations face permit suspension.
