16 <br /> <br />SECTION 3 – GREASE REMOVAL SYSTEM REQUIREMENTS <br /> <br />All FSEs and NFDs shall have an adequate grease removal system installed and exercise proper <br />kitchen best management practices to ensure that excess concentrations of FOG are not discharged <br />to the POTW. <br /> <br />All Mobile Food Units (MFUs) which, in the judgement of the Director, generate FOG-bearing <br />wastewater requiring pretreatment, shall use a commissary kitchen facility equipped with an <br />approved grease removal system, and exercise proper best management practices to ensure that <br />excess amounts of FOG are not discharged to the POTW. <br />3.1 New Construction <br /> <br />All new construction FSEs and NFDs shall submit kitchen fixture plan views and kitchen <br />waste plans showing all potential grease discharging lines, all GRSs, and connecting piping <br />to the Director or designee for approval prior to construction. The plumbing shall be <br />installed in accordance with the approved plans. Failure to submit plans or construct in <br />accordance with approved plans is a violation of this ordinance. <br /> <br />A. All new single occupancy Food Service Establishment buildings shall be <br />constructed with properly sized interceptor-style grease removal systems. Where <br />bona-fide space or gradient limitations make the use of an interceptor -style GRS <br />impractical, and with prior approval of the Director, a FSE may install properly <br />sized hydromechanical trap-style GRSs. All kitchen drains and any other drains that <br />may carry grease-laden waste shall be connected to this GRS (except the <br />dishwasher if a hydromechanical trap-style GRS is installed.) If a hydromechanical <br />trap-style GRS is installed, the kitchen may not have a garbage disposal/garbage <br />grinder/macerator or similar unit installed. See Sec. 3.5. <br /> <br />B. All new construction multi-tenant buildings (strip centers/malls) shall include a <br />separate waste line for all leasable spaces that discharges to a common 2000 gallon <br />or larger interceptor (See Sec. 3.6.E.). This waste line shall be permanently marked <br />to identify it as required by the Director. When a space is leased, sold, or rented to <br />a FSE or NFD, all kitchen drains and any other drains that may carry grease-laden <br />waste shall be connected to this waste line; no domestic sewage may be connected <br />to this line. The property owner shall be responsible for proper maintenance of this <br />interceptor in accordance with the provisions of this ordinance. <br /> <br />C. All new single occupancy Non-FSE FOG Discharger buildings shall install a <br />properly sized GRS. Interceptor-style GRSs are recommended, but <br />hydromechanical trap-style GRSs are permissible. All kitchen drains and any other <br />drains that may carry grease-laden waste shall be connected to this GRS (except the <br />dishwasher if a hydromechanical trap-style GRS is installed.) If an <br />hydromechanical trap-style GRS is installed, the kitchen may not have a garbage <br />disposal/garbage grinder/macerator or similar unit installed.
