Midland, TX Environmental Rules: Erosion Control (2026)

Chapter 11-12, Article IV of the Midland Code of Ordinances governs construction-site erosion and sediment control directly, not the county subdivision statute previously cited for this page (Tex. 003 governs commissioners courts regulating unincorporated county subdivisions and does not apply inside Midland's city limits). Section 11-12-8(A) covers small sites of at least one acre but less than five acres and large sites of five acres or more, matching the TCEQ TPDES Construction Stormwater permit thresholds. Under 11-12-8(C), every set of construction plans a city ordinance requires for review must include an erosion control plan drawing.

Under 11-12-8(D), operators must submit a signed notice of intent (NOI) or construction site notice (CSN) at least seven days before construction begins and post it at the site. Under 11-12-8(E), qualified personnel provided by the operator must inspect all areas that might discharge soil, waste, or other pollutants, and controls must be cleaned, repaired, or replaced when their capacity is reduced by 50 percent. Under 11-12-8(F), the City may inspect the site and must give written notice of deficiencies, with a correction window the Stormwater Administrator sets at not more than ten days.

Under 11-12-8(G), the City may deny a building permit, subdivision plat, site development plan, inspection, or occupancy approval if the Stormwater Administrator determines the erosion control plan drawing or site conditions don't sufficiently minimize discharge of soil, waste, and other pollutants. Section 11-12-10 separately requires developments and redevelopments of one acre or more to control post-construction runoff volumes and erosion under the City's Storm Drainage Design Manual, unless the project causes no net increase in impervious area or already holds a TPDES industrial stormwater permit.
