3. Environmental Considerations • Solid waste management • Liquid waste management • Water and energy consumption • Wastewater • Sustainable purchasing

4. Sacramento Splittail: Suisun Marsh Pollution Prevention Sanitary Sewer Overflows Water pollution is a serious problem! Stormwater Runoff

5. Chef’s Recommendation • BE AWARE: Reduce, Reuse, Recycle! • Think before you purchase, clean, fertilize, and/or dispose. • Conserve and CHOOSE WISELY! • Share your knowledge with others!

6. Pretreatment • Why pretreatment? • Effects… • Chef’s recommendations to mitigate!

7. Pretreatment Programs PERMITS—Check with your City; you may need one! Requirements may include: Fees Permit Regular Reporting Self-Monitoring Reports Sampling Enforcement

8. Why Pretreatment?FOG! • FATS, OIL and GREASE!! • Waste produced by all the different stages of food preparation, cooking and clean up. • Fats are solid at room temperature, oils are liquid at room temperature and grease is a mixture. • All types of FOG are viscous and can stick to sewer pipes causing blockages and backups.

9. Meat fats Lard Cooking Oil Shortening Condiments Dressings Butter and margarine Food scraps Baking goods Dairy products Sauces Coffee FOG a’ la CarteFrom food and cooking processes such as: • Deep or stir frying • Preparation and baking

10. Effects of FOG! • Greasy foods cause blockage of the arteries the same way they cause blockages of drain lines. • Over time pipes can decrease in diameter with the build up of FOG and minerals. • The result is a cement like matter that can decrease the area of flow significantly.

11. Effects of FOG continued • Sink drain and sewer back ups. • Sewage spills inside your facility. • Heath concerns when backups and overflows occur. • FOG, if not cleaned properly, is a vector for bacteria build up and disease. • Odors can affect the quality of your products and comfort of customers.

12. Effects of FOG continued • Unplugging sewer lines is prohibitively expensive. • Sewage clean up is just as costly. • Fines associated with health violations can be astronomical. • Loss of customers to Green Businesses.

13. Chef’s Recommendation #1Traps or Interceptors • Traps or interceptors should be installed to protect sewers from areas that produce FOG. • Areas include: food prep sinks, dishwashing sinks, pot washing sinks, mop sinks and mat washing areas • Traps allow wastewater flow to be detained long enough for FOG to separate out and float to the top for ease of removal.

14. TRAP CUTS

15. Traps or Interceptors • Traps generally do not have a long enough retention time to adequately separate FOG. Need to be designed(sized and manufactured)to handle the amount of FOG expected. • Interceptors are pretreatment devices generally over 750 gallons located outside the facility. • Need to be installed correctly (i.e. level, vented, correct position in waste stream etc.) • Should never receive solids. Routine, often daily, maintenance is needed to ensure that they reduce or prevent blockages.

16. Trap Maintenance • Traps collect solids in the bottom and FOG on the top. • Solids must be removed regularly to prevent wastes from becoming acidic and producing odorous gas. • FOG must be removed regularly as well to ensure build up does not flow into sewer lines causing backups.

17. Trap cleaning posters available through www.bappg.org

18. Traps or Interceptors • Be cautious of chemicals and additives (including enzymes, soaps, & detergents) that claim to dissolve grease. Some of these additives simply pass grease down pipes where it can clog sewer lines in other areas. • You have a right to know! Refer to MSDS sheets to protect yourself and the environment.

19. Chef’s Recommendation #2Best Management Practices The most economical way to deal with FOG in food preparation, cooking and cleaning! B M P’s

20. Never hot flush (continuously run hot water) through a grease trap Keeping the trap as clean as possible will prevent it from becoming a task no one will want to perform Scrape leftovers into a food waste container prior to washing Contract with a rendering service for recycling used cooking oil, meat, and/or trap grease B M P’s

21. B M P’s • Check with your local government solid waste program for local composting facilities or animal farms that will accept non-edible food waste. • NEVER use a garbage disposal unit. • Greasy scraps pass through interceptors/ traps and clog sewer lines causing backups. • Greasy waste transferred from landfill to wastewater treatment plants.

22. B M P’s • Used fryer oil is a valuable commodity with potential for reuse as feedstock and fuel • Always pour oil through a screen to capture waste particles prior to placing in tallow bin (stored in secondary containment to prevent accidental spills to the storm drain system)

23. Benefits • Waste reduction leads to increased operating efficiency and cost savings. • Waste minimization reduces purchasing costs. • Decreased solid waste generation reduces collection and disposal costs. • Reducing electricity and water reduces utility bills.

24. StormwaterBiggest Contributor to Water Pollution • Rainwater running off streets, roofs, and parking lots flows into the storm drain system without treatment. • Storm drains transport untreated water to local creeks, ponds, lagoons, the bay, and ocean WITHOUT TREATMENT!

25. Stormwater • Food facilities can be a significant source of stormwater pollution

26. Stormwater Runoff … Tallow bin placed next to a storm-drain that flows directly to San Francisco Bay.
