Sioux Falls operates under an Individual MS4 permit (Phase I, effective Nov. 1, 1999) issued by the South Dakota DANR. The City requires erosion/sediment control on construction sites, post-construction runoff management, and prohibits illicit discharges into the storm sewer system. Public Works enforces the program; stormwater fees are billed monthly based on impervious area, not water use.
Sioux Falls discharges to the Big Sioux River under an Individual MS4 NPDES permit administered by the South Dakota Department of Agriculture and Natural Resources (DANR) Surface Water Quality program (effective November 1, 1999, joint Phase I with SDDOT). Construction activity disturbing one or more acres requires coverage under the SD General Permit for Stormwater Discharges Associated with Construction Activities, including a Notice of Intent (NOI) and a Stormwater Pollution Prevention Plan (SWPPP) prior to ground disturbance. The City's stormwater utility (administered through Public Works) bills a monthly stormwater fee assessed by impervious surface area rather than metered water use. Common BMPs accepted by the City include detention/retention basins, vegetated swales, sediment fences, stabilized construction entrances, and permeable pavement. The City's home-rule authority for this program flows from SDCL Chapter 6-12 and the general police-power grant in SDCL § 9-29-1; state-level MS4 oversight is at SDCL Title 34A (Environmental Protection).
Illicit discharges and uncontrolled sediment runoff are enforced by City Public Works through stop-work orders, notices of violation, and municipal citation. Sioux Falls's general penalty for code violations (Sioux Falls Code § 10.99) is a Class 2 misdemeanor — up to 30 days in jail and/or up to $500 fine per offense — and each day of continuing violation is a separate offense. State-level DANR can also issue administrative penalties for unpermitted construction discharges.
