Section 22-219.6 Representative sampling and flow measurements.
Prior to the adoption of Ord. 16734 on 01/02/2001, Section 22-219.6 read as follows.
(a) Samples and measurements taken as required herein shall
be representative of the volume
and nature of the monitored discharge. All samples shall be taken at the monitoring point(s)
specified in this permit and, unless otherwise specified, before the effluent joins or is diluted by
any other waste stream, body of water or substance. All equipment used for sampling and
analysis must be routinely calibrated, inspected and maintained to ensure their accuracy.
Monitoring points shall not be changed without notification to and the approval of the City of
(b) If flow measurement is required by this permit, the appropriate
flow measurement devices
and methods consistent with approved scientific practices shall be selected and used to ensure the
accuracy and reliability of measurements of the volume of monitored discharges. The devices
shall be installed, calibrated, and maintained to ensure that the accuracy of the measurements are
consistent with the accepted capability of that type of device. Devices selected shall be capable
of measuring flows with a maximum deviation of less than 10 percent from true discharge rates
throughout the range of expected discharge volumes.
