Summary
Queen Creek's MS4 stormwater permit bars dumping anything but stormwater into the Town's storm drains, under Town Code Section 10-10-6. Construction sites disturbing an acre or more need an ADEQ permit and a site-specific pollution plan, and violations are enforced as civil or criminal offenses under Article 9-21.
No person shall throw, drain, or otherwise introduce, cause, or allow others under its or their control to throw, drain, or otherwise introduce into the Town MS4 or into the Storm Drainage System connected to the Town MS4 any pollutants or waters containing any pollutants, other than Stormwater.
Full Breakdown
Queen Creek operates as a small Municipal Separate Storm Sewer System (MS4) under EPA's Clean Water Act program, and Section 10-10-1 grounds its Stormwater Quality Management and Discharge Control Ordinance in A.R.S. Sections 11-251.66 and 49-371 and the Town's Arizona Pollutant Discharge Elimination System (AZPDES) permit. Section 10-10-6 prohibits throwing, draining or introducing any pollutant other than stormwater into the Town's MS4 or connected storm drainage system, and separately bans constructing, using, maintaining or continuing any illicit connection to that system, even one that predates this rule. Exempt discharges include water line flushing, landscape irrigation, individual residential car washing, air conditioning condensation, and firefighting flows, unless the Town's Administrator determines one is a significant pollutant source.
Construction activity gets its own rule: Section 10-10-7 requires an owner or operator disturbing an acre or more of land, or a smaller site that is part of a larger development, to obtain ADEQ permit coverage and file the Notice of Intent with the Town's Enforcement Officer before disturbing the land. A Stormwater Pollution Prevention Plan must stay on site for inspection, and if best management practices are not properly installed or maintained, the owner has seven days after notification to fix the deficiency before the Enforcement Officer issues a compliance order and refers a complaint to the County Attorney under A.R.S. Section 49-261.
Enforcement runs through Section 10-10-4, which routes violations, notices and penalties to Article 9-21 of the Town Code, with civil matters tried before the Civil Hearing Officer under Chapter 5.
Violations & Fines
Illicit discharges and connections under Section 10-10-6, and construction-site violations under Section 10-10-7, are prosecuted under Article 9-21: a first civil offense costs $250, escalating to $500 and $2,000 for repeat offenses within 12 months, with a fourth violation charged as a Class 3 Misdemeanor. The Enforcement Officer can also issue a stop work order or seek an injunction for an active construction violation.
