What is FOG? • Fats, Oils, and Grease • Fats – solid at room temperature • Examples include butter, shortening, meat trimmings, dairy • Oils – liquid at room temperature • Examples include vegetable oils and salad dressings • Grease – turns to liquid when cooking but solidifies when cooled • Examples include gravy, mayonnaise, meat fats
FOG clogs sewer lines Results in service calls for NCSD personnel
Could result in SSOs StormwaterSewer System
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 NCSD • Cleaning 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 expensive • No visible results • Test trials from various vendors • Chemical/biological treatments • No 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 SC • PCBs introduce into sewer system • Illegal dumping into grease trap by hauler • Some utilities are requiring grease traps to be secured with fencing, locks, cameras, etc • Lessons learned: • Monitor your grease trap closely • NCSD 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
