Abilene, TX Environmental Rules: Erosion Control (2026)

Division 5 of Chapter 32 requires facility owners and operators to comply with the erosion and sediment controls tied to the two state general permits that cover most Abilene construction sites: TPDES general permit TXR150000 for construction activity and TXR050000 for industrial facilities. Section 32-241(b) states these permits require the permittee to "develop, implement, and maintain a stormwater pollution prevention plan (SWP3)" and to submit a notice of intent to both TCEQ and the City as MS4 operator; smaller sites that fall under the permit's notice-only threshold instead file a construction site notice under § 32-291, delivered in person or mailed to the Stormwater Utilities Division at 555 Walnut Street, Suite 210.

The City's MS4 permit obligates it to inspect construction sites and enforce control-measure requirements, so § 32-242 gives the Administrator a right of entry during normal working hours to check a site's SWP3 against actual conditions, look for illicit connections, and collect samples. Section 32-243 lets the Administrator order a written correction of SWP3 deficiencies within 30 days. Separately, § 32-190(c) makes it a standalone violation to let sediment, concrete, asphalt, or other construction debris reach the municipal storm drain system, and gives an operator up to 72 hours to remove it once notified.

Section 32-314 extends the same control duty to stockpiles, soil piles, and material heaps on any site in the City limits that could wash into the storm system, and lets the Administrator require specific control measures to keep that from happening.
