(A) Required cleaning frequency.
(1) Unless otherwise specified by the Public Works Director, each “outdoor” interceptor in active use shall be cleaned at least once every six months or more frequently as needed to prevent the discharge of fats, oils and grease in excess of 300 mg/l into the POTW. Under the sink interceptors shall be cleaned at a minimum once every 15 days or more frequently as needed to prevent the discharge of fats, oils and grease in excess of 300 mg/l into the POTW. The Public Works Director may specify cleaning more frequently when cleaning at these intervals is shown to be inadequate. Additional pumping may be required during time periods when increased loading is anticipated.
(2) If the inspector determines that the interceptor is full, immediate steps shall be taken by the operator to pump out and clean the interceptor as soon as is practicable. The Public Works Director shall make an evaluation of the advisability of allowing discharge to continue, and may, at his or her discretion, order an immediate cessation of all discharge from the food service establishment.
(B) Notice of cleaning. Every operator shall, within ten days of each cleaning of an interceptor located on the operator’s premises, notify the Public Works Director in writing that the interceptor has been cleaned. The notice of cleaning shall include the date of the cleaning, the identity of the hauler, the site to which the contents of the interceptor were hauled and such other information as the Public Works Director may reasonably require. The operator shall submit with each notice of cleaning an invoice, manifest or other similar document from the hauler evidencing the cleaning of the interceptor. The operator shall also submit such other documentation relating to the cleaning of the interceptor as the Public Works Director may reasonably require.
(C) Cleaning procedures.
(1) The operator or an employee of the operator shall supervise the interceptor cleaning. Such person shall be present during and observe the entire cleaning operation.
(2) An operator shall cause the licensed waste hauler, transporter or any other person cleaning or servicing an interceptor to completely evacuate all contents, including floating materials, wastewater and bottom sludges and solids during servicing. Skimming the surface layer of waste material, partial cleaning of the interceptor or using any method that does not remove the entire contents of the collection device is prohibited. The suction of the floating materials shall be done prior to removal of other contents. After complete evacuation, the walls, top and bottom of the interceptor shall be thoroughly scraped and the residue removed.
(3) It shall be unlawful for an operator to allow the decanting or discharging of removed waste back into the interceptor from which the waste was removed or into any other interceptor.
(4) When cleaned, the interceptor shall be fully evacuated unless the interceptor volume is greater than the tank capacity on the vacuum truck in which case the transporter shall arrange for additional transportation capacity so that the interceptor is fully evacuated within a 24-hour period following the transporter’s inability to fully evacuate the interceptor.
(D) Disposal of interceptor pumpage. All waste removed from each interceptor shall be disposed of at a facility permitted and authorized to receive such waste in accordance with all applicable federal, state and local regulations. Fats, oils and grease removed from an interceptor shall not be recycled so as to become a food product or part of a food product for animal or human consumption. The operator shall be responsible for assuring that the waste is disposed of in accordance with all federal, state and local disposal regulations.
(E) Vacuum truck cleaning service. It shall be unlawful for an operator to allow grease interceptor waste to be removed from its premises by a transporter which does not have all applicable federal, state and local permits or registrations.
