Food Service Operations
When you think about pollutants, food is probably not the first thing that comes to mind. However, if they are not disposed of properly, food and drinks can become storm water pollutants. For example, soda pop is acidic and has a high biochemical oxygen demand (BOD). Materials high in BOD that enter the storm water drainage system result in lower dissolved oxygen levels in our waterways. Good waste handling practices help protect our water resources and environment.
Permanent Food Service Establishments
Everyday, across the University of Michigan - Dearborn campus, Dining Services and University caterers feed thousands of students, faculty, staff, and visitors. As a result, tons of food wastes are generated. To properly dispose of waste, place all solids in the trash; dispose of all liquids to the sanitary sewer; recycle items such as cardboard, glass, plastic, and metal cans; and compost appropriate food items, if composting is available.
Food service equipment washing should be done indoors, so that all wastewater goes to the sanitary sewer. This includes ventilation ducts, which may need periodic maintenance to remove grease and other contaminants. If washing is conducted outside, all wash water must be collected. This includes cleaning trash cans and garbage dumpsters, the periodic cleaning of ventilation hoods, and any other cleaning activity typically provided by contractors.
Grease traps must be properly maintained and cleaned on a regular basis to ensure their effectiveness. Grease storage drums must be properly stored to minimize the potential for spills. Drums should not be placed near docks, parking spaces, or in vehicle lanes where delivery trucks may hit them. If feasible, grease storage drums should be under a roof or other cover so spills or drips are not washed into a storm drain. If a spill occurs during pick-up, contact EHSEM for assistance at 593-5333.
It is the responsibility of food service staff to make sure all wastewater is properly disposed. Depending on the cleaning products used, the wastewater may be required to be collected as liquid waste. Check the Material Safety Data Sheets (MSDS) of the proposed cleaning products and contact EHSEM at 593-0921 for proper disposal procedures.
Temporary Outdoor Events
Groups on campus that would like to host temporary food events must obtain a temporary food service license through the state of Michigan. Prior to submitting the application, contact EHSEM at 593-4914 for proper training.
