(A) Compliance Monitoring Methods. At any facility that discharges stormwater to the MS4, the stormwater engineer is authorized to execute the following methods, or any other reasonable methods, to enforce compliance with this stormwater ordinance:
(1) Install, or to require the installation of, such devices as are necessary to conduct sampling or metering of the discharger's operations at the expense of the City;
(2) Require any facility that is reasonably determined to have discharged a pollutant or any substance that causes, continues to cause, or will cause pollution, to conduct specified sampling, testing, analysis, and other monitoring of its stormwater discharges. The stormwater engineer may specify the frequency and parameters or any required sampling or monitoring;
(3) Require any facility that has been found to have violated this ordinance to install monitoring equipment as necessary at the discharger's expense. The discharger, at its own expense, shall at all times maintain the facility's sampling and monitoring equipment in a safe and operating condition. Each device used to measure storm water flow and quality must be calibrated regularly to ensure accuracy;
(4) Require monitoring of non-storm water discharges if the stormwater engineer reasonably believes that such discharges violate the city's MS4 permit requirements;
(5) Upon request of the stormwater engineer, a facility shall submit in writing the results of any sampling or monitoring undertaken pursuant to the requirements of this article;
(6) Facility owners or operators shall maintain the results of any monitoring and any supporting documentation undertaken pursuant to this ordinance for three years; or
(7) All monitoring required by this ordinance must be performed in accordance with the established methodologies and protocols of the EPA or New Mexico Environmental Department.
