Logan, UT Environmental Rules: Stormwater Management (2026)

Logan Municipal Code § 13.14.410 bars any person from introducing, or causing to be introduced, a discharge into the municipal separate storm sewer system unless it is composed entirely of stormwater. The ban reaches the commencement, conduct and continuance of a nonstormwater discharge, so an ongoing leak is treated the same as a new dump. The code then lists the exceptions: water line flushing and other potable water sources, uncontaminated landscape irrigation, diverted stream flows, rising groundwater, foundation or footing drains, crawl space pumps, springs, firefighting activities, dye testing, and swimming pools if dechlorinated. The pool entry cites less than 1 ppm chlorine as the dechlorination level. The city engineer can also approve a discharge in writing when it is necessary to protect public health and safety. A second exception covers discharges authorized under an UPDES permit, waiver or waste discharge order administered by the Utah division of water quality, but only if the discharger is in full compliance and written approval has been granted for the discharge to the storm drain system.

Related rules sit in the same chapter. Section 13.14.420 prohibits illicit connections to the storm sewer, including connections made in the past that were legal when built. Section 13.14.430 lets the city require a person responsible for a property that is or could be the source of an illicit discharge to put best management practices in place at that person's expense. Section 13.14.440 requires the person responsible for a release to contain and clean it up, to notify emergency response agencies through dispatch immediately for hazardous materials, and to notify the city engineer no later than the next business day for nonhazardous materials, with written confirmation mailed within three business days of the telephone notice. A commercial or industrial operator keeps an on-site written record of the discharge for a minimum of three years. Separately, § 13.14.040 charges every developed parcel a stormwater utility fee based on equivalent residential units, where one ERU equals three thousand (3,000) square feet of impervious surface area.
