(1) A five-day, 20° C. biochemical oxygen demand (BOD) greater than 200 parts per million, and/or
(2) Suspended solids containing greater than 200 parts per million.
(B) Pretreatment. The Control Authority may require a discharger to install, at the discharger's expense, preliminary treatment or processing facilities as may be necessary to prevent:

(2) Interference;
(3) A violation of the discharger's categorical pretreatment standards;

(C) Grease, oil and sand interceptors. Grease, oil and sand interceptors shall be provided for the proper handling of liquid wastes containing grease in amounts that might obstruct or otherwise interfere with the operation of the POTW, or any flammable wastes, sand, or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwellings. All interceptors shall be of a type and capacity approved by the Control Authority and shall be located so as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight, and equipped with easily removable covers which, when bolted in place, shall be gastight and watertight. Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense in continuously efficient operation at all times. Owners shall keep complete records of all cleaning and maintenance of interceptors. A record copy of the invoice for any cleaning or maintenance is to be forwarded to the Control Authority within one week of its completion. If necessary, the Control Authority may establish and require specific
interceptor cleaning frequencies for individual owners to be in compliance.
