Before discharging any construction stormwater, the operator must obtain a TPDES permit when one is required and must submit an executed electronic stormwater pollution prevention plan (SWP3), a notice of intent (NOI) where applicable, and a construction site notice (CSN) to the city under subsections (a) and (b). Subsection (d) requires best management practices, including preserved vegetation, stabilized disturbed areas, sediment-tracking controls, and proper hazardous-material housekeeping, installed to the maximum extent practicable and maintained per city construction detail standards.

Any person conducting land-disturbing activity must also prepare a separate erosion control plan meeting the city drainage design manual under subsection (k), regardless of whether a state or city permit is otherwise required. 5 inches or more, per subsection (g). Large sites of five or more acres must file the NOI and CSN with the city at least two days before construction begins; sites between one and five acres must file the CSN before earth-disturbing work starts. Stabilization measures must begin within fourteen days after disturbance temporarily or permanently stops, and the city may withhold an occupancy permit until final stabilization is confirmed under subsections (l)(6) and (7). Owners and operators, and any contractor responsible for implementing BMPs, are jointly and severally liable for noncompliance under subsections (h) and (i).
