Education and Outreach 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

Monitoring and Enforcement 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

Monitoring and Enforcement 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

Program Costs, Fees, and Incentives 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

Program Costs, Fees, and Incentives 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

Building Blocks Programmatic Ordinance and Permit Ordinance 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

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

Why is FOG Characterization So 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 Site Investigation Plant 1, East Complex, Hawthorne - VOC Plume Investigation (Installed the first 19 wells onsite) Y-12 Facility Anaheim – VOC Plume Investigation, Litigation Support K-6 Facility, Torrance – Delineation of Petroleum and Chlorinated Hydrocarbons D-5 Facility, Compton – Delineate PCE impacted soil Remediation – Former D5 Facility, Hawthorne – Installation and Operation of Soil Vapor Extraction System, Site Closure Obtained in 6 months Construction/Demolition – Building 3-47, East Complex Hawthorne True turnkey investigation, design, construction

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

Need for FOG Characterization Grease Blockages are a “Middle of the Pipe” Problem and Require a Different Approach than “End of the Pipe Problems” Site Investigation Plant 1, East Complex, Hawthorne - VOC Plume Investigation (Installed the first 19 wells onsite) Y-12 Facility Anaheim – VOC Plume Investigation, Litigation Support K-6 Facility, Torrance – Delineation of Petroleum and Chlorinated Hydrocarbons D-5 Facility, Compton – Delineate PCE impacted soil Remediation – Former D5 Facility, Hawthorne – Installation and Operation of Soil Vapor Extraction System, Site Closure Obtained in 6 months Construction/Demolition – Building 3-47, East Complex Hawthorne True turnkey investigation, design, construction

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

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?
