Where preliminary treatment, pretreatment, flow-equalizing facilities, or grease, oil, grit and sand traps or other interceptors are provided for any wastewater, they shall be continuously maintained in satisfactory condition and effective operation by the owner at his or her expense.
(A) Grease removal. Grease and oil traps or other interceptors shall be provided at the user’s expense when such user operates an establishment preparing, processing or serving food and/or food products. Grease interceptors may also be required in other industrial or commercial establishments when they are necessary for the proper handling of liquid wastes containing oil and/or grease in amounts of excess of 50 mg/l, or for any flammable wastes. All such traps, tanks, chambers or other interceptors shall be of a type and capacity approved by the District and shall be readily and easily accessible for cleaning and inspection. All such interceptors shall be serviced and emptied of the waste content as required, as frequently as 30 days or as long as 90 days, at the discretion of the District, in order to maintain their minimum design capability to intercept oils and greases from the wastewater discharged to the public sanitary sewer. The operation, maintenance and repair of such equipment shall be at the sole expense of the owner. Failure to comply may result in the implementation of enforcement procedures.
(1) Waste removed from grease interceptors shall not be discharged into the public sanitary sewer. The owner shall be responsible for the sanitary disposal of such wastes.
(2) The user shall maintain written records of trap maintenance for at least two years. The user shall send a copy of the invoice for trap cleaning or similar suitable record each time the trap is cleaned, to the Board or a duly authorized representative.
(B) Sand and grit removal. Sand and grit traps or other interceptors shall be provided at the owner’s expense when they are necessary for the proper handling and control of liquid wastes containing sand and grit in excessive amounts. All such interceptors shall be of a type and capacity approved by the District and shall be readily and easily accessible for cleaning and inspection. All such interceptors shall be serviced and emptied of their solids contents as required, but not less often than every 30 days, in order to maintain their minimum design capability to intercept grit and sand prior to the discharge of waste waters to the public sanitary sewer. The operation, maintenance and repair of such equipment shall be at the sole expense of the owner. Failure to comply may result in the implementation of enforcement procedures.
(1) Wastes removed from sand and grit interceptors shall not be discharged into the public sanitary sewer. The owner shall be responsible for the sanitary disposal of such wastes.
(2) The user shall maintain written records of trap maintenance for at least two years. The user shall send a copy of the invoice for trap cleaning or similar suitable record each time the trap is cleaned, to the Board or a duly authorized representative.
