The State of Mississippi has modified its damage prevention regulations to require the use of their “Positive Response Information System” (PRIS), to communicate the status and plans for pipeline marking. Before this change, the use of PRIS was optional for facility owners. PRIS is an automated information system operated and maintained by Mississippi 811, that allows excavators, locators, facility owners or operators, and other affected parties to enter and/or determine the status of a locate request. Note that this includes positive response, where a facility owner must enter information into PRIS after a One Call notification, even if they have no facilities in the area and do not plan to place marks.
