A. The Director may at any time, with reasonable notice, require permittees to provide results of periodic measurements of its discharge which include chemical analyses and/or flow. The Director may require a sampling and/or a monitoring facility to be furnished and operated at permittee’s expense.

B. All permittees required to provide a monitoring facility shall furnish and install at an appropriate location a calibrated flume, weir, flow meter or similar device approved by the Director suitable to measure flow rate and total volume. In lieu of wastewater flow measurement and when deemed appropriate, the Director may accept records of periodic water meter readings and adjust the flow volume by suitable factors to determine peak and average flow rates for the specific industrial wastewater discharge.

C. The sampling and/or monitoring facility should normally be situated on the permittee’s premises, but the Director may, when such a location would be impractical or cause undue hardship on the user, by encroachment permit separately applied for, allow the facility to be constructed in the public street or sidewalk area and located so that it will not be obstructed by landscaping or parked vehicles.

D. Whether constructed on public or private property, the sampling and monitoring facilities shall be provided in accordance with the Director’s requirements and shall be completed within 90 days following written notification by the Director, unless a time extension is granted by the Director.

E. Those permittees required by the Director to make periodic measurements of industrial wastewater flows and constituents shall annually make the number of such periodic measurements as required in the permit.

F. When required by the Director, permittees shall install and maintain in proper order automatic flow-proportional sampling equipment and/or automatic analysis and recording equipment.

G. Permittees shall allow the City or its representatives ready access at all reasonable times to all parts of the premises for purposes of sampling or in the performance of any of their duties. The Director shall have the right to set up on the permittee’s property such devices as are necessary to conduct sampling or metering operations. Where a permittee has security measures in force, the permittee shall make the necessary arrangements with their security guards so that, upon presentation of suitable identification, personnel of the City shall be permitted to enter without delay.

H. All sampling, analysis and flow measurement procedures, equipment, results and records shall be subject at any time to inspection by the Director. (Ord. 2466 § 7, 1991).
