001 Applicability. The requirements of this chapter apply to all construction and demolition waste disposal areas required to have a permit pursuant to Chapter 2, 001.
002 Locational criteria. Construction and demolition waste disposal areas shall be located in accordance with the standards as described in this section. The application shall include documentation verifying that the solid waste disposal area complies with the following.
002.01 The vertical separation between the lowest point of the lowest cell and the predicted maximum water table elevation shall be sufficient to maintain a ten (10) foot vertical distance between deposited waste and the water table elevation based on reliable existing regional data, if available. A lesser separation distance may be approved by the Director provided the applicant shows good cause.
002.02 The application shall include a description of the land use and population density of the proposed facility and of the area surrounding the facility within one mile of the facility boundaries.
002.03 Floodplains. A construction and demolition waste disposal area or a lateral or vertical expansion of these facilities, shall not be located in a 100-year flood plain, unless the owner or operator can demonstrate that the disposal area will not restrict the flow of the 100-year flood, reduce the temporary water storage capacity of the floodplain, or result in washout of solid waste so as to pose a hazard to human health and the environment.
002.04 Wetlands. A construction and demolition waste disposal area shall not be located in wetlands.
002.05 Unstable areas. An owner or operator of a construction and demolition waste disposal area located in an unstable area shall demonstrate in the permit application that engineering measures have been incorporated into the facility's design to ensure that the integrity of the final cover system of the construction and demolition waste disposal area will not be disrupted.
002.05A An owner or operator shall consider the following factors, at a minimum, when determining whether an area is unstable:
002.05B For purposes of this section,
002.05A1 On-site or local soil conditions that may result in significant differential settling;
002.05A2 On-site or local geologic or geomorphologic features; and
002.05A3 On-site or local human-made features or events, both surface and subsurface.
002.05B1 “Unstable area” shall mean a location that is susceptible to natural or human-induced events or forces capable of impairing the integrity of some or all of the facility structural components responsible for preventing releases from the facility. This term may include poor foundation conditions, areas susceptible to mass movements, and Karst terranes.
002.05B2 “Poor foundation conditions” shall mean those areas where features exist which indicate that a natural or human-induced event may result in inadequate foundation support for the structural components of a solid waste management facility.
002.05B3 “Areas susceptible to mass movements” shall mean those areas of influence (i.e., areas characterized as having an active or substantial possibility of mass movement) where the movement of earth material at, beneath, or adjacent to the solid waste management facility, because of natural or human-induced events, results in the down slope transport of soil and rock material by means of gravitational influence. Areas of mass movement include, but are not limited to, landslides, avalanches, debris slides and flows, soil fluction, block sliding, and rock fall.
002.05B4 “Karst terranes” shall mean areas where karst topography, with its characteristic surface and subterranean features, is developed as the result of dissolution of limestone, dolomite, or other soluble rock. Characteristic physiographic features present in karst terranes include, but are not limited to, sinkholes, sinking streams, caves, large springs, and blind valleys.

003.03B Surface water courses and run-off shall be diverted from the construction and demolition waste disposal area by devices such as trenches, conduits and proper grading to minimize infiltration and erosion of cover material. The construction and demolition waste disposal area shall be constructed and graded so as to promote rapid surface water run-off without excessive erosion. Excessive erosion shall mean an erosion rate of five (5) tons per acre per year, or more.
003.03C Run-off from the active portion of the construction and demolition waste disposal area shall be handled in accordance with section 004 of this Chapter.
003.03D Regrading shall be done as required during construction and after completion to avoid ponding of precipitation and to maintain cover material integrity. On-site drainage structures and channels shall be designed for at least a twenty-four (24) hour, twenty-five (25) year storm.

Extensions of the closure period may be granted by the Department if the owner or operator demonstrates that closure will, due to circumstances beyond the operator's control, take longer than 180 days and the owner or operator has taken, and will continue to take, all steps to prevent threats to human health and the environment from the unclosed construction and demolition waste disposal area.
005.08 Following the closure of the construction and demolition waste disposal area or any part of the area, the owner or operator shall submit Construction Quality Assurance documentation, a topographical survey showing final contours, and a certification to the Department signed by an independent professional engineer registered in the State of Nebraska verifying that closure has been completed in accordance with the approved closure plan.
