(A) Measurement of SIU industrial waste flow. Any significant industrial user who is discharging industrial waste to the POTW shall provide to the Director independent access and the means and facilities for observing, measuring and sampling such industrial waste. The Director shall have full access at all times to the SIU's monitoring facility or facilities to conduct tests on quality and quantity of effluent. The volume or quantity of industrial waste discharged by any industrial user into the POTW may be determined by one or more of the following methods:
(1) If the entire volume of water used by an SIU is purchased from the city, then the volume of water purchased from the city shall be considered to be the volume of industrial waste discharged;
(2) If the entire volume of water used by an SIU is purchased from the city and the volume of water used for industrial purposes is less than the volume of water purchased from the city, the SIU shall either install and maintain a meter on the industrial waste line; or use another method approved by the Director to determine the volume of industrial waste discharged; or
(3) If any SIU now discharging or proposing to discharge industrial waste to the POTW and does not purchase its entire water supply from the city, then the volume or quantity of industrial wastes discharged by an SIU shall be determined as follows:
(a) The SIU shall install and maintain a meter or meters on all private water supply lines. The volume of industrial waste discharged shall be considered the sum of the volume of water purchased from the city and the volume of water metered from the private water supply; or
(b) The SIU shall install and maintain a meter on the industrial waste line to determine the volume of industrial waste discharged.
(B) Measurement of other non-residential flow. If any other non-residential user now discharging or proposing to discharge to the POTW and does not purchase its entire water supply from the city, then the volume or quantity of wastewater discharged by the non-residential user may be determined by one of the methods listed in division (A) of this section.
(C) Location of monitoring facilities. The Director may require an industrial user to provide and operate, at its own expense, monitoring facilities to allow inspection, sampling and flow measurement of the user's industrial waste. The monitoring facility shall be located on the industrial user's premises unless the Director determines that such a location would be impractical for purposes of providing independent and unscheduled monitoring activities or causes undue hardship on the industrial user. In such cases, with the Director's approval, the monitoring facility may be constructed in the public right-of-way or easement, in an unobstructed location. The location of the monitoring facility shall provide ample room in or near the monitoring facility to allow accurate sampling and preparation of samples for analysis. The industrial user shall maintain its monitoring facilities and sampling and measuring equipment in safe and proper operating condition. Whether constructed on public or private property, the monitoring facilities shall be provided in accordance with the Director's requirements and all applicable local construction standards and specifications. Such facilities shall be constructed and maintained in a manner to enable the Director to perform independent monitoring activities.
