Wisconsin DNR Technical Standard 1072 Horizontal Directional Drilling

Wisconsin Department of Natural Resources published a new technical standard that provides criteria for projects employing horizontal directional drilling (HDD). The standard includes procedures and practices to protect water quality by reducing sediment discharge from work areas, reducing potential for runoff to carry construction materials into waters of the state, and clarifying expectations for spill prevention and response procedures that are relevant to HDD construction methods. This includes practices to reduce the risk of runoff carrying drilling fluid from inadvertent releases (IRs), also known as a frac-out or inadvertent return, to water resources through prevention and response planning.
