Stormwater Permit
for Construction Activities

Please be aware that Notices of Intent are no longer accepted by hard copy or email. You must use the CDX portal to submit a project coverage request. CDX access information is located at the bottom of this webpage.

Stormwater Permit for Construction Activities

Construction activities disturbing one or more acres must have coverage under South Dakota’s General Permit Authorizing Stormwater Discharges Associated with Construction Activities (General Permit). This includes construction support activities* and construction sites that are part of a larger common plan of development or projects being done in phases. If the total area of the plan is over one acre, a permit is required for the duration of the project.

Construction activities include but are not limited to:

  • Clearing, grading, or excavation;
  • Road or access road construction;
  • Construction of residential, commercial, and industrial buildings or property;
  • Installing cable lines, phone lines, and pipelines (excluding oil/gas pipelines); and,
  • Demolition activities.

* Construction support activities are construction related activities that specifically support your construction site and are included in your site’s acreage. This includes but is not limited to:

  • Concrete or asphalt batch plants;
  • Equipment staging yards;
  • Materials storage areas;
  • Excavated material disposal areas; and/or,
  • Borrow areas.

To obtain coverage under this General Permit, the Notice of Intent (NOI) must be submitted at least 15 days prior to the commencement of construction. Please be aware that a permit will not be issued until all necessary information has been received, including payment of the annual fee. If construction of your site is already in progress, submit the completed NOI immediately.
NOIs must also include the first year's stormwater fee, billed to the owner of the project, as follows:

Construction Stormwater Permit Forms:

  • SDDANR is now using the EPA CDX portal for all stormwater construction permits. This portal will be used for new NOI submissions, change requests for existing permits, and termination requests. Please note that new NOI submissions are still required to have a signed and notarized Certification of Applicant form from the project owner, which must be uploaded when you submit your project request. Additionally, Contractor Authorization forms will still need to be submitted by email or hard copy mail. With this new portal, everyone who needs access to permit information will need to have an account. Please use the following User Guides to create an account and gain access to the various construction permits you are associated with.

  • New Account CDX User Guide – If you do not have an account in CDX, you will need to follow these steps.
  • Existing Account CDX User Guide – If you have an existing account in CDX, the steps are slightly different for you.
  • Existing Organization ID Search Guide – If there is an existing active CDX account for someone from your organization, this guide will assist in making sure you link to the same Organization ID as them.
  • Request Permissions for an Existing NOI User Guide – After your account is created, this guide will assist in getting access to permits. All permits will need to be renewed once a signatory has created their account and gained access to the permit. Anyone can get access at any time, but only the signatory can sign off on the renewal.
  • Contractor Authorization Must be filed by all contractors doing earthwork or who are responsible for day to day erosion and sediment control measures. Must be signed by the contracting company.
  • Certification of Applicant
