South Dakota State Environmental Review (9-SD-a)
State Environmental Review Process
9-SD-a.1 – Contact DENR
Developers should contact the South Dakota Department of Environmental and Natural Resources (DENR) in the early stages of the project planning so DENR can assist the developer align Federal and state environmental review processes, if applicable. SDEPA Memorandum, at p. 1.
9-SD-a.2 to 9-SD-a.3 – Does the Proposed Project Trigger SDEPA?
A project that meets any of the thresholds below is subject to environmental review pursuant to the South Dakota Environmental Policy Act:

9-SD-a.4 to 9-SD-a.5 – Has the Proposed Project Undergone Federal NEPA Review?
If the proposed project has undergone a federal NEPA review and the applicable agency has issued a detailed environmental impact statement as required by NEPA, the project is exempt from the state environmental review process. 34A-9 S.D., § 11.
9-SD-a.6 – Conduct Scoping Meeting(s)
Prior to the environmental review and the preparation of an Environmental Impact Statement (EIS), DENR or another relevant agency must conduct one or more scoping meeting to solicit public input regarding the proposed project’s environmental impacts from the county residences in which the proposed action is to be located. 34A-9 S.D., § 6.
9-SD-a.7 – Draft Environmental Impact Statement (DEIS)
As early as possible DENR or another relevant state agency may prepare or have prepared a Draft Environmental Impact Statement (DEIS) describing in detail the proposed action and reasonable alternatives to the action. The DEIS should also briefly discuss, on the basis of information available to the agency at that time, the information required to be included in the final environmental impact statement. 34A-9 S.D., § 5; 34A-9 S.D., § 7. The DEIS should be prepared in accordance with the procedural requirements relating to citizen participation of the National Environmental Policy Act and related implementing regulations. 34A-9 S.D., §§ 5, 7. The purpose of the DEIS is to “inform the public and other public agencies as early as possible about proposed actions that may significantly affect the quality of the environment, and to solicit comments which will assist the agency in determining the environmental consequences of the proposed action.” 34A-9 S.D., § 6.
The DEIS should resemble in form and content the EIS to be prepared after DENR receives and considers public comments on the proposed project. 34A-9 S.D., § 6. The DEIS, at minimum, should include a detailed statement setting forth the following:
- A description of the proposed action and its environmental setting;
- The environmental impact of the proposed action, including short-term and long-term effects;
- Any adverse environmental effects that cannot be avoided if the proposal is implemented;
- Alternatives to the proposed action;
- Any irreversible and irretrievable commitments of resources that would be involved in the proposed action if implemented;
- Mitigation measures proposed to minimize the environmental impact; and
- The growth-inducing aspects of the proposed action.
