010. Water Well Decommissioning.
\n\t010.01\n General Requirements.\n The well cavity, casing, and annular space, of all water wells to be decommissioned must be filled, plugged, and sealed, in accordance with the appropriate procedure described below. Any licensed water well contractor constructing a water well for any customer must, as a part of the agreement, include the proper decommissioning of each water well and test hole constructed to explore for ground water pursuant to the agreement. A landowner may only decommission a driven sandpoint water well on land owned by him/her and used by him/her for farming, ranching, or agricultural purposes or as his/her place of abode. For wells constructed after October 1, 1988, but not constructed according to this Chapter, the Department must issue a declaratory ruling pursuant to 011 of this Chapter prior to decommissioning.\n
\n\t010.02\n Preliminary Work.\n Prior to decommissioning a water well, the depth of the well and the static water level must be measured, and an investigation must be made to determine the details of the well construction, including annular fill material and seal placement. Potential sources of well construction details include:\n
\n\t010.02(a)\n The personal records of the owner;\n
\n\t010.02(b)\n The contractor that drilled the well;\n
\n\t010.02(c)\n The registration forms on file with the Nebraska Department of Natural Resources, available on its website;\n
\n\t010.02(d)\n Water well contractors familiar with the area; and\n
\n\t010.02(e)\n Water well records on file with the University of Nebraska-Lincoln Conservation and Survey Division, School of Natural Resources.\n
\n\t010.03\n Decontaminating.\n Disinfectant equivalent to at least 200 ppm chlorine must be introduced into the well before any material is placed into the well (Table 1). The disinfectant can be in a liquid, granular, or pellet form. This will also decontaminate the fill material placed adjacent to the water-bearing zones.\n
\n\t010.04\n Obstructions.\n Every effort must be made to remove obstructions. If they cannot be removed, the well cavity must be filled with approved fill material in accordance with 001.10(c) of this Chapter from the bottom of the well to a point immediately above the obstruction. If this is not possible, a five foot non-slurry bentonite grout plug must be placed above the obstruction.\n
\n\t010.05\n Material Volume.\n The volume of material required to decommission a water well can be determined using Table 3. Volumes for each interval that is to be either filled or sealed must be calculated prior to beginning. Materials used and calculated volumes must be consistent. If they are not, then:\n
\n\t010.05(a) \n Additional material must be added to replace lost volumes until the interval is filled or sealed; or\n
\n\t010.05(b) \n If material bridges in the well (evidenced by calculated amount of filler/sealer being too much), operations must stop until the bridge is removed by high pressure jetting, drilling, or other, methods.\n
\n\t010.06\n Well Decommissioning Materials.\n Approved fill material (001.10(c), 010.06(b) of this Chapter) or grout material (010.06(a) of this Chapter) must be used to decommission water wells. Grout plugs and seals must be used to prevent water movement into or between water-bearing zones; approved fill material may be used where grout plugs or seals are not required.\n
\n\t010.06(a)\n\tGrout Material.\n\tGrout material found in 001.08 of this Chapter can be used as a seal in decommissioning water wells.\n
\n\t010.06(b)\n\tFill Material.\n\tFill material to be used in water wells in intervals where grout plugs or seals are not required, must be disinfected sand, gravel, or crushed stone except that native earth material may be used in large diameter bored or dug wells greater than 24 inches in diameter because of the volume required. All fill material must be free of potentially toxic chemical residue and trash such as leaves and foreign materials. All fill material must be sized and introduced into the well at a rate to avoid bridging.\n

If no primary seals were placed at the confining layer, then every effort must be made to place a five-foot primary seal at each confining layer according to methods outlined in 010.09(e)(1) of this Chapter and plugs must be placed inside the casing adjacent to the newly installed primary seals (see Figure 15).\n
\n\t010.09(e)(1)(ii)\n\tFlowing Water Wells.\n Decommissioning these wells requires stopping the flow of water through the casing and/or annular space. If water is flowing through the casing, the well must be shut-in to ensure that flow will not come up the annular space.\n
\n\t010.09(e)(1)(ii)(A)\n If water is flowing through the casing, the well must be shut-in or capped to ensure that flow will not come up the annular space or outside the casing for a driven well with open hole below.\n
\n\t010.09(e)(1)(ii)(B)\n\tIf the well was constructed without primary seals or water flows up the annulus, a five-foot seal must be placed in the annular space adjacent to the confining layer according to 010.09(d)(1) of this Chapter. Neat cement must be utilized for these seals. The seal must be allowed to cure a minimum of 24 hours prior to continuing the decommissioning process in 010.09(e)(1)(ii)(D) of this Chapter.\n
\n\t010.09(e)(1)(ii)(C)\n\tIf the well was constructed with primary seals and water does not flow up the annulus, stop the flow of water through the casing by placing a neat cement plug in the casing or well cavity through a tremie line or by using an expandable plug. This plug should be placed across from the primary seal.\n
\n\t010.09(e)(1)(ii)(D) Once the flow is stopped, five-foot plugs must be placed in the casing across from each annular seal. Bentonite grouts can be used for these plugs above the confining layer once flow has been stopped. The rest of the well must be de commissioned as described in 010.07 of this Chapter.\n
\n\t010.09(e)(1)(ii)(E)\n\tThe exact location of these wells must be flagged for at least one year after decommissioning.\n

\n\t010.09(f)(2)\n Dig down to the top of the borehole and cut off the loop pipe at least six feet below the surface. Pump the remaining loop full of bentonite or cement slurry. The remainder of the borehole is to be decommissioned as described in 010.07(d) or 010.09(b)(4) of this Chapter; or\n
\n\t010.09(f)(3)\n Pump the header and loops full of bentonite or cement slurry if the loop field is under a paved parking lot or building.\n
\n\t010.10\n Documentation.\n A record that includes the materials used, the quantity of those materials, location of placement thereof, and mix specifications, including the type and viscosity of bentonite grouts, must be maintained on every decommissioned water well, including test holes.\n
\n\t010.11\n Reporting Decommissioning.\n A notice of decommissioning for all water wells except test holes must be submitted to the Director of the Department of Natural Resources on the Notice of Decommissioning form supplied by the Department of Natural Resources within 60 days of the decommissioning of the water well as required in Neb. Rev. Stat. § 46‑602 as follows:\n
\n\t010.11(a)\n The pump installation contractor or water well contractor must submit written notice of the decommissioning of a water well to the Department of Natural Resources.\n
\n\t010.11(b)\n If both a water well contractor and a pump installation contractor are involved in the decommissioning of a water well, the pump installation contractor must submit the notice of decommissioning to the Department of Natural Resources.\n
\n\t010.11(c)\n If a landowner decommissions a driven sandpoint water well on land owned by him/her and used by him/her for farming, ranching, or agricultural purposes or as his/her place of abode, the landowner must report the decommissioning to the Department of Natural Resources.\n
