DEP requires that only licensed plumbers install grease interceptors. A licensed plumber can determine the required size of grease interceptor needed depending on the size and nature of your business. For technical assistance, plumbers and business owners may write to the DEP’s Bureau of Wastewater Treatment, Compliance Engineering Section using the contact information listed below.
DEP encourages businesses to do everything possible to limit the impact of FOGs on the sewer system. DEP provides signs which can be posted above sinks to make FOGs reduction efforts more visible to a business’s employees. Both the FOGs from a business’s grease interceptor as well as waste cooking oil can be recycled or collected and disposed of by a fat renderer or other grease recycling company that is licensed as a trade waste hauler or private carter by the City of New York Business Integrity Commission (BIC).
There are two types of grease that can be picked up by a BIC licensed waste hauler: yellow grease (used cooking oil) and brown grease (from grease traps). Yellow grease is liquid and will often be picked up for free because it carries a market value when recycled. Brown grease is more viscous and solid, allowing businesses to either dispose of it in their solid waste stream or hire a private hauler for removal. Please consult with a licensed trade waste hauler or private carter for information about their specific rates and fees.
