Summary
Celina prohibits dumping anything but rain into the city's storm drain system, with narrow exceptions for things like landscape runoff and dechlorinated pool water.
This article prohibits unauthorized discharges into the storm drain system in accordance with TPDES phase II MS4 permit TXR040000 part III section A.3.(a)(2)a. No person shall release discharges into the municipal storm drain containing any pollutants that cause or contribute to a violation of water quality standards, other than stormwater or authorized nonstormwater discharges.
Full Breakdown
Under City Code § 13.10.004, it's unlawful to release any pollutant into Celina's municipal storm drain system (MS4) that causes or contributes to a water-quality violation, unless the discharge is stormwater or falls into one of nineteen listed exempt categories such as water line flushing, landscape irrigation runoff, or emergency firefighting flows. The rule implements the city's TPDES Phase II MS4 permit (TXR040000) and applies to any discharge entering the storm drain system within city limits. The director can revoke the affirmative defense for an exempt discharge once it's identified as a pollutant source and 14 days' written notice has passed.
Violations & Fines
Discharging pollutants to the storm drain outside the listed exemptions violates § 13.10.004; the city administers and enforces the article through the city manager or director of engineering.
