§ 6-13.704. Monitoring facilities.

(a)

Any user, at the discretion of the Director, shall be required to install and maintain monitoring facilities or devices to allow inspection, sampling, or measurements in the facility sewer or plumbing systems and shall also be required to provide, install, and operate sampling or monitoring equipment at the user's expense. These facilities must be situated on the user's premises. However, the Director may allow monitoring facilities to be constructed off-premises at the user's expense.

(b)

All users making periodic measurements must furnish and install at their own expense at the sampling well or other appropriate location a calibrated flume, weir, flow meter, or similar device approved by the Director and suitable to measure the industrial wastewater flow rate and total volume. A flow indicator, recorder, or totalizing register may be required by the Director. In lieu of wastewater flow measurement, the Director may accept records of water usage to determine peak and average flow rates for the specific industrial wastewater discharge. A suitable calibration schedule must be approved by the Director.

(c)

When one or more users discharge into a common sewer, the Director may require installation of a separate monitoring facility for each user. Also, when in the judgment of the Director, there is a significant difference in wastewater pollutants and characteristics produced by different operations of a single user, the Director may require that separate monitoring facilities be installed for each separate discharge. A combined waste stream formula may be applied.

(d)

If the monitoring facility is inside the user's fences, there must be accommodations to allow access for City personnel. There must be ample operating area in or near such sampling points and equipment to allow accurate sampling and compositing of samples for analysis. The user must assure that access and sampling and measuring equipment are maintained in a safe and proper operating condition.

(e)

The sampling and monitoring facilities must be installed in accordance with the City's design requirements and all applicable construction standards, safety devices, and specifications. Construction must be completed within ninety (90) days following written notification from the City.

(f)

The user must provide written notification to the Director upon completion of the sampling and monitoring facilities.

(g)

Monitoring or metering facilities must be provided with a security closure that can be locked with a City provided lock during sampling or monitoring.

(h)

Unrestricted access to monitoring facilities must be available to authorized City personnel at all times.
