§ 27-163. Monitoring and reporting.

(a)

Discharge reports:

(1)

Industrial dischargers may be required to file a discharge report on a form supplied by the department at such times as may be designated by the director.

(2)

The discharge report shall include, where appropriate, the following: nature of the process, volume, rates of flow, volume of water irreversibly used in production, hours of operation, concentrations of controlled pollutants, or other information which relates to the generation of waste.

(b)

Records: All persons who discharge or propose to discharge industrial waste may be required to maintain such records as effluent flows and pollutant concentrations as are necessary to demonstrate compliance with the requirements of this division. Such records shall be made available upon request by the director.

(c)

Monitoring:

(1)

The owner or operator of any premises or facility discharging industrial wastes may be required to install at his own expense suitable monitoring equipment, including but not limited to control manholes and/or sampling points with approved meters and appurtenances to facilitate accurate observation, sampling and measurement of wastes. Such equipment shall be maintained in proper working order and kept safe and accessible at all times.

(2)

The monitoring equipment shall be located and maintained on the industrial disposal premises outside the building. When such a location would be impractical or cause undue hardship on the user, the director may allow a 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 vehicle. All sampling ports shall be constructed above ground and not subject to any groundwater or rainwater infiltration or dilution.

(3)

When more than one (1) discharger can discharge into a common sewer, the director may require installation of separate monitoring equipment for each. When there is a significant difference in wastewater characteristics produced by different operations of a single discharger, the director may require that separate monitoring facilities be installed for each separate operation.

(4)

Whether constructed on public or private property, the monitoring facilities shall be constructed in accordance with the director's requirements and all applicable construction standards and specifications.

(d)

Frequency of monitoring: The director may require a discharger to monitor his discharge and report the results of the monitoring at specified intervals.

(e)

Pollutants to be monitored: The director shall provide to each discharger who is determined to require self-monitoring a complete list of wastewater constituents for which the discharger must provide monitoring. The director shall provide information regarding discharge prohibitions and limitations for pollutants to be self-monitored.

(f)

Inspection; sampling and analysis:

(1)

Compliance determinations: Compliance determinations with respect to section 27-161 prohibitions and limitations may be made on the basis of either instantaneous grab samples, or composite samples of wastewater. Composite samples may be taken over a twenty-four-hour period, or over a longer or shorter time span, as determined necessary by the director to meet the needs of specific circumstances.

(2)

Analysis of industrial wastewaters: Laboratory analysis of industrial wastewater samples shall be performed in accordance with the current edition of Standard Methods or other procedures approved by the director.

(g)

Reporting of accidental discharges: If, for any reason, a discharger does not comply with any prohibition or limitation in this division, the discharger shall immediately notify the director so that corrective action may be taken to protect the storm drainage system. In addition, a written report addressed to the director detailing the date, time and cause of the accidental discharge, the quantity and characteristics of the discharge, and corrective action shall be filed by the discharger within five (5) days of the occurrence of the noncompliance.
