If an artesian condition is encountered in any geotechnical soil boring or blast hole, the artesian water strata must be contained pursuant to NRS 534.060 and NAC 534.378, and the geotechnical soil boring or blast hole must be sealed by placing concrete grout, cement grout, bentonite chips or neat cement by tremie pipe in an upward direction from the bottom of the geotechnical soil boring to the surface. The owner and lessor of the land on which a geotechnical soil boring is located, the operator of the exploration project and the drilling contractor for the project shall take the necessary steps to prevent the loss of water above or below the surface and to prevent the vertical movement of water in the borehole.
