A. Grease and Sand/Oil Interceptors, as described by the International Plumbing Code (IPC), shall be required of any Commercial User when the SGRWRF determines they are necessary for the proper handling of wastewater containing FOGS in excessive amounts, except such interceptors shall not be required for residential dwelling units.
B. Any Commercial User utilizing a three compartment sink shall be required to have either a grease interceptor or grease trap installed at its own expense and shall be required to comply with maintaining the device as outlined in the St. George City Pretreatment Operating Plan.
C. All construction plans for interceptors shall be submitted to SGRWRF for review and approval prior to installation. All interceptors shall be of a type, construction, and capacity approved by SGRWRF.
D. All interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, water tight, and equipped with easily removable covers, which are gas and water tight.
E. All newly constructed commercial structures, strip malls, multi-tenant planned-occupied buildings, or planned-un-occupied buildings, shall install independent six-inch (6") wastewater discharge lines stubbed out within each designated future food establishment unit. If a new source commercial structure, strip mall, or multi-tenant building has planned occupancy by one or more businesses that do not generate FOG, and therefore do not need a grease interceptor, and the owner of the structure does not facilitate the installation of independent six inch wastewater discharge line and install a common interceptor, then no future food establishments shall be permitted, unless facilities are retrofitted for independent lines.
F. All newly constructed “stand alone” commercial structures, strip malls, multi-tenant planned-occupied buildings, where a three compartment sink will be utilized, will be required to install a grease interceptor.
G. All existing commercial or industrial businesses shall have one (1) year to install an interceptor upon notification by SGRWRF, where required by SGRWRF standards.
H. Interceptors for businesses that have closed shall be dewatered and cleaned by the owner of said establishment. A representative of SGRWRF may inspect and verify this process has been completed to the satisfaction of SGRWRF.
I. Grease Traps are only allowed in place of grease interceptors when in the opinion of the Manager it is physically impossible to install a grease interceptor outside of the building or business. As such, a variance request from the owner or lessee of the property must be made to SGRWRF with a certification letter from a duly licensed Utah plumber or engineer. (Ord. 2018-27, 11-14-2018)
