Violate any requirement under the federal Marine Protection, Research, and Sanctuaries Act of 1972.c. Construction of the waste disposal unit will not cause or contribute to significant degradation of wetlands.d. To the extent required under section 404 of the federal Clean Water Act or applicable State wetlands laws, any unavoidable wetlands impacts will be mitigated.(d) The Department shall not issue a permit to construct any disposal unit of a sanitary landfill if, at the earlier of (i) the acquisition by the applicant or permit holder of the land or of an option to purchase the land on which the waste disposal unit will be located, (ii) the application by the applicant or permit holder for a franchise agreement, or (iii) at the time of the application for a permit, any portion of the proposed waste disposal unit would be located within: (1) Five miles of the outermost boundary of a National Wildlife Refuge.(2) One mile of the outermost boundary of a State gameland owned, leased, or managed by the Wildlife Resources Commission pursuant to G.S.113-306, prior to July 1, 2013, except as provided in subdivision (2a) of this subsection.(2a) Five hundred feet of the outermost boundary of a State gameland owned, leased, or managed by the Wildlife Resources Commission pursuant to G.S.113-306, prior to July 1, 2013, when all of the following conditions apply: a. The waste disposal unit will only be permitted to accept construction and demolition debris waste.b. The disposal unit is located within the primary corporate limits of a municipality located in a county with a population of less than 15,000.c. All portions of the gameland within one mile of the disposal unit are separated from the disposal unit by a primary highway designated by the Federal Highway Administration as a U.S. Highway.(3) Two miles of the outermost boundary of a component of the State Parks System.(e) A sanitary landfill for the disposal of construction and demolition debris waste shall be constructed with a liner system that consists of a flexible membrane liner over two feet of soil with a maximum permeability of 1 x 10-5 centimeters per second. The flexible membrane liner shall have a minimum thickness of thirty one-thousandths of an inch (0.030"), except that a liner that consists of high-density polyethylene shall be at least sixty one-thousandths of an inch (0.060") thick. The flexible membrane liner shall be installed in direct and uniform contact with the soil layer. The Department may approve an alternative to the soil component of the liner system if the Department finds, based on modeling, that the alternative liner system will provide an equivalent or greater degree of impermeability.(f) A sanitary landfill, other than a sanitary landfill for the disposal of construction and demolition debris waste, shall be constructed so that the post-settlement bottom elevation of the liner system, or the post-settlement bottom elevation of the waste if no liner system is required, is a minimum of four feet above both the seasonal high groundwater table and the bedrock datum plane contours. A sanitary landfill for the disposal of construction and demolition debris waste shall be constructed so that the post-settlement bottom elevation of the flexible membrane liner component of the liner system is a minimum of four feet above both the seasonal high groundwater table and the bedrock datum plane contours.(g) A permit holder for a sanitary landfill shall develop and implement a waste screening plan. The plan shall identify measures adequate to ensure compliance with State laws and rules and any applicable local ordinances that prohibit the disposal of certain items in landfills. The plan shall address all sources of waste generation. The plan is subject to approval by the Department.(h) The following requirements apply to any sanitary landfill for which a liner is required: (1) A geomembrane base liner system shall be tested for leaks and damage by methods approved by the Department that ensure that the entire liner is evaluated.(2) A leachate collection system shall be designed to return the head of the liner to 30 centimeters or less within 72 hours. The design shall be based on the precipitation that would fall on an empty cell of the sanitary landfill as a result of a 25-year-24-hour storm event.
