Gopher State One Call Information

Gopher State One Call (GSOC) is the Minnesota one call notification system established to act as a communication link between underground facility operators, homeowners, and excavators in Minnesota. GSOC is a 501 (c) (6) non-profit organization formed in 1987 in response to the legislature’s adoption of Minnesota Statutes Chapter 216D. GSOC was approved by the Commissioner of Public Safety in 1988 as the statewide one call center. Chapter 216D requires anyone who engages in any type of excavation using machine-powered equipment of any kind, or explosives, to file a locate request at least 48 hours, excluding the day of notification, weekends and holidays, before excavation can begin. GSOC collects information from anyone who is planning to excavate and transmits it to facility operators who may have underground facilities near the excavation site. After receiving a notice from GSOC, facility operators mark the approximate location of an underground facility with paint or flags, respond to the ticket electronically, or determine the work area is clear. Facility operators may then provide a response through GSOC’s Positive Response site for anyone to view the results of the located underground facilities.
