Illinois statewide rule: Illinois Plumbing Code § 890.510

Commercial kitchens must have a grease interceptor, with all grease-carrying fixtures directed to it.
Food waste disposers may not discharge into the grease interceptor, and water-cooled interceptors are prohibited.
Minimum size: the interceptor must hold at least half the liquid capacity of the connected fixtures on the same floor (60% if it sits on a floor below). Fixture capacity in gallons = length × width × depth in inches ÷ 231.
Your sanitary district or city (for example MWRD, Fox Metro or a city FOG program) can add pumping schedules, permits and hauler rules on top of this.
