FOG Language Hydro-Mechanical Grease Interceptor. A plumbing appurtenance that is installed in the sanitary drainage system to intercept free-floating (FOG) fats, oils and grease from the wastewater discharge. Continuous separation is accomplished by air entrainment, buoyancy and interior baffles. Gravity Grease Interceptor. A plumbing appurtenance of not less than 500 gallon capacity that is installed in the sanitary drainage system to intercept free-floating (FOG) fats, oils and grease from the wastewater discharge. Separation is accomplished by gravity during a retention time of not less than 30 minutes. Copyright PDI 2012

ORDINANCE Sec. XXXX Interceptor required. (New and Existing) Each FSE and FPE shall discharge all waste from sinks, dishwashers, drains, and any other fixtures or sources through which fats, oils, or grease may be discharged into the POTW into a properly maintained and functioning interceptor that complies with the requirements of the City Code of Ordinances Copyright PDI 2012

ORDINANCE Sec. XXX Maintenance shall evacuate accumulated solids, fats, oils, grease and all other material(s) from each interceptor at a frequency not less often than every ninety (90) days and within two (2) working days whenever twenty-five (25) percent or more of the wetted height of the interceptor is reached Copyright PDI 2012

ORDINANCE Sec. XXX Record keeping For each interceptor each FSE and FPE shall maintain all records that document each inspection, repair, cleaning, evacuation, service, or pumping of each interceptor Copyright PDI 2012
