7. Best Management Practices (BMPs)
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
The importance of exterior housekeeping particularly in material handling areas and areas near storm water catch basins and swales

Pros: FSEs Have a Vested Interest in Disposal of Waste, FOG Inspector Can Verify Proper Disposal
Cons: More Admin Burden for Haulers and FSEs

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

12. 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

13. 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

14. 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

15. 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

16. 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

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 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

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”
Site Investigation

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
