(A) All industrial users who discharge or propose to discharge into the system shall maintain such records of production and related factors, effluent flows, and pollutant amounts or concentrations as are necessary to demonstrate compliance with the requirements of this subchapter and any applicable state or federal pretreatment standards or requirements.
(B) Such records shall be made available upon request by the Superintendent. All such records relating to compliance with pretreatment standards shall be made available to officials of the U.S. EPA upon demand. A summary of such data indicating the industrial user's compliance with this subchapter shall be prepared as requested and submitted to the Superintendent.
(C) The owner or operator of any discharge unit discharging industrial wastes into the system shall install at his own expense suitable control manholes or access points, and monitoring equipment to facilitate the accurate observation, sampling, and measurement of wastes. Such equipment shall be maintained in proper working order and kept safe and accessible at all times. Sampling methods, location, times, durations, and frequencies are to be determined on an individual basis subject to approval by the Superintendent.
(D) Wastewater volume determination. The volume of flow used for computing industrial waste surcharges shall be the metered water consumption of the person except as provided in this division.
(1) If the discharge unit discharging industrial wastes into the system procures any part, or all, of its water from sources other than a metered, public water system, all or part of which is discharged into the system, the discharge unit shall install and maintain at its expense water meters of a type approved by the Superintendent for the purpose of determining the volume of water obtained from those other sources. Access to these meters shall be made available to the Superintendent or his designee at any reasonable time. The accuracy of said meters shall be verified at the discharge unit's expense on a biennial basis at a minimum or at the request of the Superintendent, by an independent testing company.
(2) The discharge unit discharging industrial wastes into the system must install and maintain at its own expense metering devices for determining the volume of waste being discharged to the system, from which the industrial waste surcharge would be computed. The measuring devices shall be of a type approved by the Superintendent.
(3) The Superintendent may require the installation of devices for measuring the volume of waste discharged if these volumes cannot otherwise be determined from the metered water consumption records. Any metering device for determining the volume of waste discharged to the system shall be installed, owned and maintained by the discharge unit responsible. Following approval and installation, such meters may not be removed without the consent of the Superintendent.
(E) The monitoring equipment shall be located and maintained on the discharge unit's premises on the outside of the building. When such a location would be impractical or cause undue hardship on the user, the Superintendent may allow such facility to be constructed in the public street or sidewalk area, with the approval of the public agency having jurisdiction over such street or sidewalk, and located so that it will not be obstructed by public utilities, landscaping or parked vehicles.
(F) Whether constructed on public or private property, the monitoring facilities shall be constructed in accordance with the Superintendent's requirements and all applicable construction standards and specifications.
