The Fats, Oils and Grease (FOG) program regulates food establishments, which can discharge fats, oils and grease into the public sewer system. Food establishments are required to pretreat their wastewater using grease interceptors to remove FOG and grease prior to discharge to the sewer system.
- Reduce commercial, industrial and institutional fats, oils and grease discharge into sewer system
