(A) The Wastewater Operations Manager will conduct monitoring on all SIUs, no less than twice per calendar year.
(B) Monitoring of SIUs can be either scheduled or unscheduled.
(C) The charge to the SIU for each monitoring period shall be $250 per day, plus all analytical costs.
(D) Significant industrial users with batch discharges shall notify the Wastewater Operations Manager at least 24 hours prior to discharge upon request of the Wastewater Operations Manager.
(E) In addition to the monitoring fee, each SIU with a state issued permit shall install at its own expense a suitable control manhole or other access means, together with such necessary appurtenances in or on each building lateral sewer to facilitate observations, sampling and measurement of the wastewater. Such manholes or other access means and sampling and testing devices shall be constructed and maintained in a safe and proper condition to the Wastewater Operations Manager's satisfaction, as detailed in building and plumbing codes and other applicable rules and regulations of the city. Although this access point shall be constructed at the expense of the user, it shall be under the control of the utility. If locating such facilities on the SIU's property would be impractical, the SIU may apply to the utility for a right-of-way or for permission to construct on public property.
(F) The utility shall provide necessary sampling equipment during a monitoring period for control manholes or other access means. Sampling equipment shall, unless otherwise specified by the Wastewater Operations Manager, include a device for automatically measuring flow and a device for automatically taking a composite sample of wastewater during a 24-hour period. There shall be ample room in or near facilities to allow accurate sampling and preparation of samples for analysis.
(G) The utility shall implement the applicable monitoring requirements:
(1) During each monitoring period, measure the volume of flow and sample and analyze the discharge from each SIU for all parameters contained in the state issued permit, except for Total Toxic Organics (TTOs), which shall be sampled and analyzed no less than once per calendar year, if required per the SIU's permit.
(2) The utility will follow the sample types and analytical methods described in SIU's state issued permit.
(3) The utility shall collect samples at the sample located specified in the state issued permit.
(4) The utility shall sample and analyze the discharge from any industrial user, including SIUs with state issued permit, for any parameter as necessary to achieve and/or maintain compliance with the requirements of the city's NPDES permit and/or this subchapter.
(5) The utility shall record and maintain all sampling and analytical data for the permitted facilities in accordance with the city's NPDES permit.
(H) All wastewater samples must be representative of the user's discharge. If onsite treatment operations are utilized, the Wastewater Operations Manager reserves the right to require sampling of process wastewater prior to pre-treatment and before discharge to the public collection system. Wastewater monitoring and flow measurement equipment shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
