Note: Most states have enacted laws and regulations to protect wetlands. In many cases, these rules are established to define the state's role in the "§404 permit/§401 certification process." This process involves the U.S. Army Corps of Engineers and your state environmental agency. To learn more about the wetlands permitting process go to the CICA Wetlands Regulations/Permit page.

Primary State Wetlands Web Page. This web page should explain the state wetlands program and provide links to various wetlands resources.

Construction Permit Process - State Rules

    How Are Wetlands Activities Regulated by South Dakota? The Department of Environment and Natural Resources monitors activities in South Dakota's wetlands. Most of the Department's wetlands regulations relate to water quality standards.

    Mitigation Measures. Applicants must include a plan to avoid, minimize, or compensate for any adverse effects that result from a project.

Regulatory Definitions
    Wetlands. Wetlands are "areas inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions including swamps, marshes, bogs, and similar areas." Wetlands are considered "surface waters of the state" under South Dakota's water quality regulations. Surface waters are lakes, ponds, streams, rivers, wetlands, and any other body or accumulation of water on the land surface that are considered to be waters of the state but not waste treatment systems, including treatment ponds designed to meet the requirements of the collection ponds, or stormwater retention ponds designed to meet the Clean Water Act requirements.

    Regulated Wetland Activities. The discharge of pollutants for any source cannot impair or destroy wetlands except when allowed under § 402 and § 404 of the federal Water Pollution Control Act. Raw or treated sewage, garbage, rubble, unpermitted fill materials, municipal wastes, industrial wastes, or agricultural wastes which produce floating solids, scum, oil slicks, material discoloration, visible gassing, sludge deposits, sediments, slimes, algal blooms, fungus growths, or other offensive effects may not be discharged or caused to be discharged into surface waters of the state.

    Exempt Wetland Activities. All surface water discharge permits are subject to an antidegradation review before their renewal unless the facility is operating at or below design flows and pollutant loadings; the existing effluent quality is in compliance with all the discharge permit limits; the discharge has not degraded the water quality from its status on March 27, 1973; the permitee has upgraded or erected a new facility since March 27, 1973; or the discharge is made for the beneficial use of wildlife propagation, stock watering, and irrigation and the discharge is not expected to contain toxic pollutants.
