The South Dakota Transportation Commission is considering amendments to Administrative Rules of South Dakota (ARSD) numbered: • 70:01:02:01 – Minnehaha County speed zone rule; • 70:01:02:39 – Jackson County speed zone rule; • 70:01:02:59 – Sully County speed zone rule; • 70:07:01:01 – Definitions; • 70:07:04:09 – Reasons for Debarment; • 70:07:04:10.02 – Hearing request; and • 70:07:04:15 – Term of debarment. The proposed speed zone rule amendments will change speed limits on State Trunk Highway 115 north of Sioux Falls in Minnehaha County, U.S. Highway 83 near Onida in Sully County, and South Dakota Highway 248 in and around Kadoka in Jackson County. The proposed speed zone rule changes will also update highway references and eliminate speed limit provisions that are no longer needed because of highway jurisdictional transfers. The reasons for the proposed speed zone rule amendments are to enhance safety, add clarity, and repeal speed limits for highways that are not under the jurisdiction of the South Dakota Department of Transportation. The South Dakota Department of Transportation is also proposing amendments to administrative rules relating to contractor prequalification to submit bids for highway construction projects. The proposed amendments will change when the terms “business” and “person” are used in the rules. The purpose of the proposed amendments is to clarify when the rules apply to a natural person and when they apply to a business entity.
