Summary
Edinburg regulates stormwater discharges into its MS4 storm sewer system, requiring construction sites to file pollution prevention plans and banning illicit non-stormwater discharges into storm drains, gutters, and ditches.
No person shall discharge or cause to be discharged into the municipal storm drain system or watercourses any materials, including, but not limited to, pollutants or waters containing any pollutants that cause or contribute to a violation of applicable water quality standards, other than stormwater.
Full Breakdown
Section 98.30 of the Edinburg City Code governs the city's municipal separate storm sewer system (MS4). Construction site operators disturbing one or more acres must prepare a stormwater pollution prevention plan (SWP3) before receiving a building or site development permit, and must submit it to the city; smaller sites must still control soil, sediment, and vehicle tracking off-site. The ordinance bans discharging anything other than stormwater into the storm drain system or watercourses, prohibits illicit connections such as sanitary sewage lines tied into the MS4, and lets the city suspend a violator's MS4 access during an emergency discharge. Violations are prosecuted as misdemeanors with fines up to $500 per violation per day.
Violations & Fines
Discharging pollutants into the storm drain system, illicit connections, or failing to file a required SWP3 is a misdemeanor punishable by a fine up to $500 per day.
