Any alternative requirements established under this section must:
005.01C Final surface grades and side slopes of the closed solid waste disposal area shall prevent run-on and runoff from eroding or otherwise damaging the final cover.
005.01D Appropriate vegetative cover shall be established and maintained as soon as practical after final grading.

005.05 The owner or operator of a solid waste disposal area shall begin implementation of the closure plan required in 005.10 and 005.11 of this rule within thirty (30) days after the date on which the facility receives the final volume of waste or, if the facility has remaining capacity and there is a reasonable likelihood that the facility will receive additional wastes, no later than one year after the most recent receipt of wastes.
005.03A The existence of a closed solid waste disposal area on the property;
005.03B The type, depth and location of the waste on the property, as well as the existence of any monitoring systems; and

005.06 The owner or operator of a solid waste disposal area shall complete closure activities in accordance with the closure plan within 180 days after the last receipt of waste. 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 solid waste disposal area.
005.07 Following the closure of a solid 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.

Requests for approval shall demonstrate that disturbance of the final cover, liner, or other component of the containment system, including any removal of waste, will not increase the potential threat to human health and the environment and shall include:
005.05A The owner or operator shall notify the Department, in writing, of the date of the receipt of the final volume of waste, the date of the initiation of closure, and the date of the installation of the final cover system, as applicable. The owner or operator shall place copies of these notices in the operating record.
005.05B Extensions beyond the one-year deadline for beginning closure may be granted by the Director if the owner or operator demonstrates that the facility has the capacity to receive additional wastes and the owner or operator has taken and will continue to take all steps necessary to prevent threats to human health and the environment from the unclosed solid waste disposal area.
