  3. Building Blocks • Technologies • Best Management Practices (BMPs) • Waste Grease Disposal • Programmatic Building Blocks

  4. Automatic Grease Traps GreaseInterceptors Building Blocks Technologies

  5. Building Blocks Technologies • Grease Interceptors • Best conventional technology, proper maintenance is critical, monitoring device to be tested in Phase II • Passive Grease Traps • Valuable for FSEs that cannot or should not install an interceptor, proper maintenance is critical • Automatic Grease Traps • To be tested in Phase II • Additives (Biological) • FSE and sewer line applications to be tested in Phase II

  6. Building Blocks Best Management Practices (BMPs) Kitchen BMPs • Structural BMPs – Removal of food grinder, install drain screens, yellow grease barrel • Other BMPs – Liquid grease collection, plate and cookware scraping, signage, spill clean-up • Records/logs – Employee training, GRE maintenance / disposal and yellow grease disposal

  7. Building Blocks Best Management Practices (BMPs) Sewer Line Cleaning • Sewer Collection System • Develop standard grease-related sewer cleaning procedures • Use post-cleaning CCTV to verify cleaning effectiveness • Characterize sewer line “hot spots” and develop an appropriate cleaning procedure

  8. Building Blocks Waste Grease Disposal • Track waste grease hauling and disposal • Certify haulers and disposal sites • Proposed four-part manifest system

  9. 4-Part Manifest System 1 Hauler Signs Generator? 2 Hauler & Disposal Site Signs 3 Hauler & Disposal Site Signs • Alternative 1 – 4th Part to the Lead Agency, All Responsibility on the Hauler DisposalSite Generator Hauler LeadAgency 4 Hauler & Disposal Site Have Signed • Alternative 2 – 4th Part to the Generator, Hauler Responsible for Proper Hauling, FSE Responsible for the Waste 1 Hauler Signs Generator? 2 Hauler & Disposal Site Signs 3 Hauler & Disposal Site Signs Generator Hauler DisposalSite LeadAgency Monthly Log of Activities 4 Hauler & Disposal Site Have Signed Pros: FSEs Have a Vested Interest in Disposal of Waste, FOG Inspector Can Verify Proper Disposal Cons: More Admin Burden for Haulers and FSEs

  10. Building Blocks Programmatic • Education and Outreach • Monitoring and Enforcement • Program Costs, Fees, and Incentives • Ordinance • FOG Characterization

  11. Building Blocks Programmatic Education and Outreach • Food Facilities (in multiple languages) • BMP flyers (in multiple languages) • Kitchen posters (in multiple languages) • Training videos (in multiple languages) • Fact sheets explaining the program (in multiple languages) • Workshops • Hands-on training from inspector • General Public • BMP flyers • Apartment building posters • School campaigns • Local newspaper & radio spots • Workshops

  12. Building Blocks Programmatic Monitoring and Enforcement • FSE Inspection Approach • Health Department Inspector Screening audits • Grease Removal Equipment (GRE) Inspector Dedicated to inspecting interceptors and traps • FOG Inspector Minimum of annual detailed inspections focusing on Hot Spots and issues from Health and GRE Inspector

  13. Building Blocks Programmatic Monitoring and Enforcement • Enforcement • Typical enforcement consists of gradual violation structure focused on re-education • Elevated enforcement if discharger “causes or contributes to a blockage or SSO” based on Line Cleaning Report or CCTV evidence

  14. Building Blocks Programmatic Program Costs, Fees, and Incentives • Cost Recovery • Fees Should be Based on the Recovery of Costs that a City or Agency will Incur to Control the FOG • Grease related sewer line cleaning costs • FSE monitoring and enforcement costs

  15. Building Blocks Programmatic Program Costs, Fees, and Incentives • FSE Initial Fee • One-time application fee for preliminary funding • FSE Ongoing Fee • Based primarily on their water usage • Discount for FSEs with properly designed and maintained grease interceptors

  16. Building Blocks Programmatic Ordinance • Ordinance and Permit • Ordinance - Legal Authority • Discharger of FOG may not cause or contribute to a SSO or blockage • Grease Interceptor (GI) recognized as Best Conventional Technology (BCT) • Kitchen BMPs required for all FSEs in the program • Permit - Establishes the detailed requirements for the program

  17. Building Blocks Programmatic FOG Characterization • Identification of grease-related sewer line “hot spots” and “hot spot” areas • Identification of the true cause(s) of the hot spots (CCTV inspection) • Inspection or auditing of food service establishments (FSEs) • Integration of this information to be used for the development of an effective FOG Control Program • Recommend developing interactive database/GIS system

  18. Why is FOG CharacterizationSo Important? 1.Determine What is Causing Your Grease Blockage • Excessive grease loading • Improper sewer line design, structural issues, or roots • Ineffective sewer line cleaning 2.Develop a Plan to Manage Those Causes So You Can Prevent Sewer Overflows

  19. Grease Blockage Causes Excessive Grease Loading Grease Blockage Ineffective Sewer Line Cleaning Improper Sewer Line Design, Structural Issues, or Roots

  20. Need for FOG Characterization • Grease Blockages are a “Middle of the Pipe” Problem and Require a Different Approach than “End of the Pipe Problems”

  21. “Middle of the Pipe” Problem Sewer line grease blockage (c/o Monterey Regional Water Pollution Control Agency)

  22. Need for FOG Characterization • Identify and Characterize the Problems and Focus Your Resources Accordingly • Where is the grease coming from? • Where are the blockages occurring and why? • Are there design or structural issues with the sewer line that are contributing to the problem? • What are your largest problems or needs? • Where should your inspection, education, and line cleaning resources be focused? • Where are you going to have the greatest success in reducing sewer overflows?

  23. Need for FOG Characterization • Proper FOG Characterization Will Provide You with the Data You Need to Budget, Plan, Inspect, and Educate Effectively • It Can be Done at the Initiation of Your Program or to Upgrade an Existing Program

  24. GIS Display of SSO’s and Potential Upstream FOG Sources

  25. FOG Characterization Outcome • Attack the Grease at Each “Hot Spot” with the Appropriate Approach Hot Spot #1: Residential upstream, no sewer line issues Approach: Education & improved sewer line cleaning Hot Spot #2: Some FSEs & apartments upstream, sag in sewer Approach: Consider sewer line upgrade, improved sewer line cleaning, FSE source control & education Hot Spot #3: Many FSEs upstream, no sewer line issues Approach: FSE source control & education, improved sewer line cleaning
