(2) Existing facilities. Food service facilities existing prior to the date of the City of Tampa Grease Management Ordinance shall be permitted to operate and maintain existing grease interceptors or traps provided their grease interceptors or traps are in good operating condition.
The city may require an existing facility to install a new grease interceptor or trap that complies with the requirements of the Florida Building Code—Plumbing, as amended (current edition) or to modify or repair any noncompliant plumbing or existing grease interceptor or trap when any one (1) or more of the following conditions exist:
a. The facility is found to be contributing grease in quantities sufficient to cause line stoppages or necessitate increased maintenance on the wastewater collection system.
b. Grease concentrations exceed four hundred (400) mg/l on wastewater effluent as determined by sampling performed by the GMP inspector.
c. The facility does not have a grease interceptor or trap.
d. The facility has an irreparable or defective grease interceptor or trap.
e. Remodeling of the food preparation or kitchen waste plumbing system is performed which requires a plumbing permit to be issued by the City of Tampa.
f. The facility is sold or undergoes a change of ownership.
g. The facility does not have plumbing connections to a grease interceptor or trap in compliance with the requirements of this article.
(c) Plumbing connections. Grease interceptors or traps shall be installed in accordance with Florida Building Code—Plumbing, as amended (current edition). Wastewater from sanitary facilities shall not be introduced into the grease interceptor or trap under any circumstances.
(d) Records maintenance. Each food service facility shall maintain a logbook in which a record of all interceptor maintenance is entered. Maintenance information shall include, but not be limited to, date and time of the maintenance, estimated gallonage removed from interceptor or trap, any defects in the grease interceptor or trap, details of any repairs required and dates of repair completion, changes in operations, or wastewater constituents and characteristics, receipts from grease haulers, plumbers, parts suppliers, plumbing layout, sizing or flow rate calculations for grease trap or interceptor, etc., and any other records pertaining to the interceptor. This logbook shall be made available for review upon request. Records shall be maintained for a period of one (1) year. Each facility shall provide, upon request of the GMP inspector within ten (10) days, drawings of sufficient detail to depict the plumbing layout of the facility.
(e) Grease interceptors. Grease interceptors shall be designed and installed in accordance with the Florida Building Code—Plumbing, as amended (current edition) and shall be operated and maintained as follows:
(1) Pumping and maintenance. Each food service facility shall be responsible for the costs of pumping, cleaning, and maintaining its grease interceptor. All food service facilities that have grease interceptors shall utilize a registered grease hauler. Pumping services shall include the complete removal of all contents, including floating materials, gray water, bottom sludge, and solids from the interceptor. Grease interceptor cleaning shall include scraping excessive solids from the walls, floors, baffles, and all piping.
It shall be the responsibility of the grease hauler to inspect an interceptor during, or immediately after the pumping procedure to ensure that the interceptor is clean and that all fittings and fixtures inside the interceptor are in working condition and functioning properly. If the interceptor is not functioning properly, the grease hauler shall notify the owner in writing. The notice shall include a sufficient description of the malfunction.
(2) Interceptor pumping frequency. Each food service facility shall have its grease interceptor pumped prior to attaining any of the following criteria:
a. When the settled solids layer exceeds the invert of the outlet pipe (typically eight (8) inches in depth);
b. When the total volume of captured grease and solid material displaces more than twenty-five (25) percent of the capacity of the interceptor;
c. When the interceptor is not retaining or capturing oils and greases;
d. When a blockage or back up has occurred; or
e. When sanitary sewer contents have been introduced or diverted into the grease retention system.
(3) Inspection. Grease interceptors shall be inspected by a GMP inspector as necessary to assure compliance with this article.
(4) Disposal. Wastes removed from each grease interceptor shall be disposed of at a facility permitted to receive such wastes. Grease, solid materials, or gray water removed from interceptors shall not be returned to any grease interceptor, private sewer line or to any portion of the city's treatment works.
(f) Grease traps. Grease traps shall be installed in accordance with the Florida Building Code—Plumbing, as amended, (current edition) and shall meet the following criteria:
(1) Flow control device. Grease traps shall be equipped with a device to control the rate of flow through the unit. The rate of flow shall not exceed the manufacturers rated capacity recommended in gallons per minute for the unit. Each food service facility is responsible for maintaining appropriate flow control devices.
(2) Venting. The flow-control device and the grease trap shall be vented in accordance with the Florida Building Code—Plumbing, as amended (current edition). The vent shall terminate not less than six (6) inches above the flood-rim level or in accordance with the manufacturer's instructions. Each food service facility is responsible for maintaining appropriate venting of the grease trap.
(3) Cleaning and maintenance. Each food service facility shall be solely responsible for the cost of grease trap cleaning and maintenance. Each facility may contract with a registered grease hauler or it may develop a written protocol and perform its own grease trap cleaning and maintenance procedures. Cleaning and maintenance must be performed before the total volume of captured grease and solid material displaces more than twenty-five (25) percent of the total volume of the grease trap. Each facility shall determine the frequency at which their grease trap shall be cleaned, but all grease traps shall be opened, inspected, cleaned, and maintained at a minimum of once per week.
(4) Inspection. Grease traps shall be inspected by a GMP inspector as necessary to assure compliance with this article and to assure proper cleaning and maintenance is being performed.
(5) Disposal. Grease and solid materials removed from a grease trap shall be removed by a registered grease hauler unless the grease is in a solid, dry form, mixed with an oil absorbent in an enclosed bag or container, and does not exceed five (5) pounds.
(g) Additives. Any chemicals, enzymes, emulsifiers, live bacteria or other grease cutters or additives, used for the purpose of grease reduction shall, be approved by the GMP inspector prior to their addition to grease interceptors or traps. Applicable information concerning the composition, frequency of use and mode of action of the proposed additive shall be sent to the city together with a written statement outlining the proposed use of the additive(s). The city may request a sampling port installed by the food service facility at the facility's expense to demonstrate the additive will work. The city, upon evaluation of all of the information received, shall permit or deny the use of the additive in writing. Permission to use additives may be withdrawn by the city at any time.
(h) Alternative grease removal devices or technologies. Alternative devices and technologies such as automatic grease removal systems shall be subject to written permission by the director prior to installation.
