(a) Any person discharging liquid wastes containing excessive amounts of grease or any flammable waste, sand or other harmful substances shall provide grease, oil and/or sand separators/traps when they are necessary for the proper handling, except that such separators shall not be required for premises used exclusively for residential purposes. Separators/traps shall comply with the rules and regulations established by the Director of Public Utilities and shall be located for accessible inspection and cleaning.
(1) All new food service establishments shall be required to install at least a 1000-gallon (two compartment) outdoor grease separator/trap or submit plans from a State of Ohio registered design professional who has calculated the proper size of the grease separator/trap with menu and cooking activities included in the calculation. In the event an existing facility has a grease separator/trap that is either under-designed or substandard in accordance with this Section, the owner(s) shall be notified in writing of the deficiencies and required improvements and given a compliance schedule to conform to the requirements of this policy. For cases in which outdoor-type grease separators/traps are infeasible to install, existing food service establishments shall be required to install adequate and approved internal in-floor recessed grease separators/ traps for use on individual fixtures including sinks and other potentially grease-containing drains.
(2) Where grease, oil and/or sand separators/traps are provided or required, they shall be maintained continuously in a safe, satisfactory and effective operational condition by the owner at their expense. When samples are collected, the concentration for oil and grease cannot exceed 250 mg/L grab sampled or an average of 100 mg/L. The establishment is in violation if wastewater from the grease separator/trap exceeds these limits when discharging to the sanitary sewer. The owner of the property is responsible for routine cleaning, maintenance and repair, and associated record keeping for the grease separator/trap. Grease separators/traps shall be checked a minimum of once per month to ensure compliance with the maintenance schedule.
(3) Upon inspection by the Toledo Lucas County Health Department or the Control Authority, the establishment shall provide the following written documentation for their cleaning procedures: dates of monthly checks, dates of grease trap cleaning, amount of solids and grease removed, method of disposal, and manager's signature. Written documentation shall be maintained on-site for the inspector's review and shall be kept on record for a period of three (3) years. Failure to maintain on-site records and falsification of records may result in a penalty as referenced in Appendix A.
(b) No person shall cause to be discharged, either directly or indirectly, any of the following strictly prohibited substances into the treatment works of the City:
(1) Any material added to the drains or grease separator/trap used to reduce, remove, or emulsify the waste materials in the grease separator/trap (more than 1% including enzymes, detergents, and surfactants) as part of the maintenance;
(2) Any water from dishwashers equipped with booster heaters and/or using hot water, which passes through the grease separator/trap at a temperature in excess of 120ºF. A temperature step down valve or other permanent solution shall be installed to lower water temperature before passing through the grease separator/trap.
