FOG INITIATIVE“Cease the Grease”
• What is FOG?
• Issues at NCSD
• Combating the problem
What is FOG?
• Fats, Oils, and Grease
•Fats – solid at room temperatureExamples include butter, shortening, meat trimmings, dairy
•Oils – liquid at room temperatureExamples include vegetable oils and salad dressings
•Grease – turns to liquid when cooking but solidifies when cooled
Examples include gravy, mayonnaise, meat fats
How a Grease Trap works
Why is FOG a
problem?
FOG clogs sewer lines
Results in service calls for NCSD personnel
Stormwater Sewer System
Could result in SSOs
Clogs in Sewer Lines Result In:Service calls from NCSD Crews
Costly repairs to sewer lines
Overflows into streets, ditches, and waterways
Backups into businesses and homes
Build-up in wet wells
Results in maintenance costs for NCSD
Costs to NCSDCleaning of pump station wet-wells
$38,500 for ½ Northwoods PS (FY 2014)$38,500 for ½ Northwoods PS (FY 2015)$43,000 for ½ Popperdam PS (FY 2015)
New Vacuum truck $400,000
60,000 Gallons pumped from PS
Disposal Costs
Grease pushed to WWTP
• WWTP not designed to handle grease
• New stricter NPDES Permit
How NCSD is handling FOG?Tried using “bugs”
Very expensiveNo visible results
Test trials from various vendorsChemical/biological treatmentsNo visible results
New test trial FY 2015
Best method for handling FOG?Reduce/eliminate introduction into the system
Food Service Establishments• Best Management Practices• Cleaning Log• Inspection Log• Inspection Report• Brochure• Postings
Amendment to the Use Resolution• Requiring BMP for food service establishments
• Allowing NCSD to recoup cost for service call relating to grease
• Civil Penalty ($100/day) for not implementing BMP
• Civil Penalty ($100/day/instance) for not maintaining records
Elsewhere in SCPCBs introduce into sewer systemIllegal dumping into grease trap by haulerSome utilities are requiring grease traps to
be secured with fencing, locks, cameras, etc
Lessons learned:Monitor your grease trap closelyNCSD program will help
NCSD is asking for your help
Reduce amount of grease disposed of into sewer system
Reduce amount of grease build-up in sewer system
Maintaining grease traps
Keeping sewer rates as low as possible
