South Dakota Department of Agriculture and Natural Resources: Farming and Environment

The South Dakota Department of Agriculture and Natural Resources (DANR) consolidates regulatory and programmatic authority over the state's agricultural sector and environmental systems into a single cabinet-level agency. Its jurisdiction spans crop and livestock production, water quality, pesticide management, soil conservation, and air permitting. Understanding how DANR structures its authority clarifies which operators require licenses, which activities trigger environmental review, and where federal and state oversight intersect.

Definition and scope

DANR was formed through the 2021 merger of the former Department of Agriculture with the former Department of Environment and Natural Resources, an administrative consolidation effective July 1, 2021 (South Dakota Codified Law §1-43). The combined agency administers programs under both agricultural and environmental mandates, operating across 66 of South Dakota's 66 counties.

The agency's agricultural mandate covers:

  1. Licensing and inspection of grain dealers, grain warehouses, and seed dealers under SDCL Title 49 and Title 38
  2. Pesticide applicator certification and product registration under SDCL 38-20A
  3. Animal industry programs including brand inspection, livestock disease control, and dairy plant licensing
  4. Soil conservation and agronomy services coordinated through 69 local conservation districts

The environmental mandate covers:

  1. Surface water and groundwater quality permits under the South Dakota Pollutant Discharge Elimination System (SDPDES), which operates as a delegated program under the federal Clean Water Act (33 U.S.C. §1251 et seq.)
  2. Air quality permits and emissions monitoring under authority delegated from the U.S. Environmental Protection Agency
  3. Underground storage tank (UST) regulation and corrective action oversight
  4. Solid and hazardous waste facility permitting under SDCL Title 34A

Scope boundary: DANR's authority is geographically limited to South Dakota. Federal lands, including National Forest land and lands held in trust for federally recognized tribal nations, fall primarily under U.S. Forest Service, Bureau of Land Management, or tribal environmental authority rather than DANR jurisdiction. Federally permitted facilities may face concurrent EPA oversight that operates independently of DANR processes. Activities on South Dakota tribal governments' territories are governed by tribal environmental codes and applicable federal law, not by DANR.

How it works

DANR operates through two primary programmatic divisions: Agriculture and Natural Resources. Each division maintains licensing, inspection, and enforcement functions administered from the Pierre headquarters, with field staff distributed across regions.

For agricultural operators, the licensing pathway begins with an application to the relevant DANR program office. Pesticide applicators, for example, must pass a competency examination aligned with EPA's Worker Protection Standard categories before receiving a commercial or private applicator certificate. Certificates require renewal on a schedule set by SDCL 38-20A, and continuing education hours in pest management are verified by DANR before renewal is issued.

For environmental permitting, facilities that discharge to state waters apply for an SDPDES permit. DANR reviews applications against water quality standards established in ARSD 74:51, issues a draft permit for public comment, and finalizes terms after a minimum 30-day public notice period. Concentrated Animal Feeding Operations (CAFOs) above the 1,000 animal unit federal threshold require both a CAFO-specific SDPDES permit and, depending on location, a review against county zoning ordinances administered separately by county governments such as Hughes County or Minnehaha County.

Air quality permits for stationary sources — including large grain elevators and livestock operations — are processed under a tiered system. Major sources, defined by EPA thresholds, require a Title V operating permit. Minor sources require a state permit issued under ARSD 74:36.

Common scenarios

Crop producer applying a restricted-use pesticide: The operator must hold a current private applicator certificate from DANR. Application records must be retained for 2 years under SDCL 38-20A-35.

Feedlot expansion crossing the 1,000 animal unit threshold: The operator must file for an SDPDES CAFO permit, submit a nutrient management plan, and demonstrate compliance with setback and land application requirements under ARSD 74:51.

Grain warehouse seeking a public license: South Dakota requires a public grain warehouse license under SDCL 49-45. DANR inspectors verify bin capacity, scale accuracy, and financial bonding requirements. Bonds are calculated based on bushel capacity — the minimum bond amount under SDCL 49-45-57 is set at a rate per bushel as periodically updated by rule.

Leaking underground storage tank at a rural cooperative: The responsible party must notify DANR's Petroleum Release Compensation Fund (PRCF) program within 24 hours of confirmed release under ARSD 74:03:23. DANR oversees the corrective action process, which may involve soil and groundwater assessment and remediation under EPA's UST regulations at 40 CFR Part 280.

Decision boundaries

The primary decision boundary operators encounter is between state-only permits and federally delegated permits. DANR administers delegated federal programs — SDPDES, portions of air permitting, and the UST program — meaning DANR issues the permit, but EPA retains oversight authority and can intervene if state program standards fall below federal minimums.

A second boundary separates agricultural exemptions from regulated-facility requirements. Under both the Clean Water Act and the Clean Air Act, certain normal farming practices qualify for agricultural exemptions. However, once a livestock operation crosses quantitative thresholds (1,000 animal units for CAFOs; emissions thresholds for air), the exemption is lost and full permitting is required. DANR staff make threshold determinations based on animal unit calculations defined in ARSD 74:04.

Contrast with the South Dakota Game, Fish and Parks agency, which holds separate authority over wildlife, hunting and fishing licensing, state park administration, and recreation — functions that DANR does not administer despite overlapping natural resource territory.
