The city may conduct compliance monitoring at such times and frequencies as are deemed necessary to carry out the purposes and intentions of this title. Compliance monitoring for categorical industries shall be performed at least once per year. The city reserves the right to verify methods of sampling, flow measurements and analyses, and to inspect records pertaining to all requirements of the discharger’s permit. The city also reserves the right to collect and analyze samples of compliance status.

Each user shall provide and operate at its own expense a monitoring facility to allow inspection, sampling, and flow measurements of each sewer discharge to the city. Each monitoring facility shall be situated on the user’s premises. In those situations where such a location would be impractical or cause undue hardship on the user, the city may concur with the facility being constructed in the public street or sidewalk area, providing that the facility is located so that it will not be obstructed by landscaping or parked vehicles. The director, whenever applicable, may require the construction and maintenance of sampling facilities at other locations (for example, at the end of a manufacturing line or wastewater treatment system).

There shall be ample room in or near such sampling facility to allow accurate sampling, flow measurement and preparation of samples for analysis. The facility, sampling, and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user. All monitoring facilities shall be constructed and maintained in accordance with all applicable local construction standards and specifications.

The director may require the user to install monitoring equipment as necessary. All devices used to measure wastewater flow and quality shall be maintained and calibrated in accordance with manufacturers’ recommendations to ensure their accuracy.

At such time that the city collects a sample, a representative split of the sample shall be offered to the discharger for analysis. All costs incurred in the performance of measurements, tests and analyses done by the city as verification of the discharge compliance shall be charged to the discharger in accordance with Chapter 14.40 LMC. (Ord. 3220 § 2, 2016; Ord. 2742 § 2, 2008; Ord. 1831 § 18, 1991; Ord. 1705, 1989)
