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

All forms located on NCSD Website

www.ncsd-sc.com

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
