A. Each permitted industrial user, upon determination by the city, shall be required to furnish and install (or, at the city’s option, reimburse the city for such procurement and installation) on each discharge line to the city’s collection system:

1. A flow-weighted, composite sampler with protective enclosure.

2. A flow-actuated and/or time-actuated grab sampler with protective enclosure.

3. A continuous recording flow-meter with logger and protective enclosure.

B. The city may, when necessary, also require users to install such monitoring and recording devices necessary to monitor any of the following parameters:

1. pH;

2. Dissolved oxygen (DO);

3. Total carbon (TC);

4. Oxidation/reduction potential (ORP);

5. Temperature;

6. Conductivity.

C. Those industrial users designated by the city shall construct, at their own expense, a wastewater metering and sampling station, together with the corresponding flow measuring and sampling equipment. This station shall be constructed on the building sewer lateral and at a location approved by the city. This station shall be accessible to the industrial waste inspector at all times. Construction shall be completed prior to discharge into the sewer or in accordance with an approved schedule. The city may require such installations on each building sewer lateral.

D. The monitoring station should be situated on the user’s premises. The city may, when such a location is impractical or causes undue hardship on the user, allow the station to be constructed in the public street or sidewalk area. The station location will not be obstructed by fencing, landscaping or parked vehicles so as to prevent reasonable access for city inspectors.

In the event that a monitoring facility is allowed to be constructed in the public street or sidewalk area, the user shall indemnify, hold harmless and defend the city against any claim, cause of action, disability, loss, liability, damage, cost or expense, which in any way arises out of the monitoring facility or its use.

E. Whether constructed on public or private property, the station shall be built and maintained in accordance with the city’s requirements and all applicable local construction standards, codes and specifications. There shall be ample room in or near the station to allow accurate sampling and sample preparation. Construction shall be completed within ninety days following written notification by the city that such monitoring facilities are required, unless a time extension is granted by the city.

F. The station, sampling and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user.

G. The flow-measuring device may be connected to a data logger when requested by the city which will be able to interface with the city’s computer.

H. Any person who intentionally or negligently tampers, falsifies, or knowingly renders inaccurate any monitoring device shall be punished by a fine of not more than ten thousand dollars, or imprisonment in a county jail for not more than six months or both.

I. In the event that the installation of a monitoring facility is not practical, the point of monitoring and inspection may be other alternatives approved by the city.
