(A) Cleaning/pumping. The user at the user's expense shall maintain all grease traps to assure proper operation and efficiency and maintain compliance such as not to cause pass through and violation of the city KYPDES permit or NPDES effluent water quality standards. Maintenance of grease trap shall include the complete removal of all contents, including floating materials, wastewater, and bottom sludge and solids. This work shall be performed by a qualified and licensed hauler. Decanting or discharging of removed waste back into the trap from which it was removed or any other grease trap, for the purpose of reducing the volume to be disposed, is prohibited. This service shall also include a thorough inspection of the trap and its components. Any needed repairs shall be noted. Repairs shall be made at user's expense.
(B) Cleaning/pumping frequency.
(1) The grease trap must be pumped out completely a minimum of:
(a) Once every six months;
(b) More frequently if the total volume of floating grease and settled solids in the trap are equal to or greater than 25% of the total trap volume (25% rule);
(c) Anytime the grease trap effluent concentration of total oil and grease exceeds 250 mg/l; or
(d) As determined by the WSS, as needed to prevent carryover of grease into the sanitary sewer system.
(2) Upon request of the FSE owner, the DEU or his or her designee may reduce the cleaning/pumping frequency requirement should it be proven that this action will not cause significant maintenance problems to the city. Such a request will not be evaluated until the FSE owner can demonstrate a track record of compliance and that the current requirement is overly protective for said FSE.
(C) Disposal. All waste removed from each grease trap must be disposed of at a facility approved to receive such waste in accordance with the provisions of this program. In no way shall the pumpage be returned to any private or public portion of the city's sanitary sewer collection system. All pumpage from grease traps must be tracked by a manifest, which confirms pumping, hauling, and disposal of waste. The customer must obtain and retain a copy of the original manifest from the hauler.
(D) Maintenance log. A grease trap cleaning/maintenance log indicating each pumping for the previous 24 months shall be maintained by each food service establishment (FSE). This log shall include the date, time, amount pumped, hauler, and disposal site and shall be kept in a conspicuous location for inspection. Said log shall be made available to the WSS or his representative upon request.
(E) Submittal of records.
(1) Each user shall submit all cleaning and maintenance records to the WSS. The maintenance records shall include the following information:
(a) Facility name, address, contact person, and phone number.
(b) Company name, address, phone number, and contact name of person responsible for performing the maintenance, cleaning, pumping, or repair of grease trap.
(c) Types of maintenance performed.
(d) Dates maintenance was performed.
(e) Date of next scheduled maintenance.
(f) Copies of manifests.
(2) The user shall be required to submit maintenance records to the WSS on a biannual basis (twice per year). Records shall be submitted by March 1 and September 1 of each year. The records shall be submitted to:
City of Ashland
Attn: Wastewater Collection
P.O. Box 1839
Ashland, KY 41101
(3) The WSS or designees will perform periodic inspections of these facilities and shall notify the user of any additional required maintenance or repairs. Upon written notification by the WSS, the user shall be required to perform the maintenance and records of said maintenance within 14 calendar days. Upon inspection by the WSS or designees the user may be required to install, at his or her expense, additional controls to provide a complete system which prevents discharges of undesirable materials into the wastewater collection system.
