Under IPC (adopted via Maryland Building Performance Standards), food establishments here must control fats, oils & grease (FOG) with a grease interceptor or trap, and typically register with the local sewer/wastewater authority. Grease interceptors are required under Maryland's adopted plumbing code, with FOG permits issued by the local sewer/wastewater authority.
Size the interceptor with our grease-trap sizing calculator, compare units in the grease-trap catalog, and confirm the local FOG permit with St. Mary's County Health Department, Division of Environmental Health (contact above).
