(a) The permit applicant for an industrial solid waste landfill (ISWLF) unit (site) permit shall prepare a site study in accordance with Paragraph (c) of this Rule, and submit the site study to the Division. The Division shall review the site study for a proposed new site prior to consideration of an application for a permit. Following review of the site study, the Division shall notify the applicant in writing that either:
(1) the site is deemed suitable for establishing an ISWLF unit and the applicant may prepare an application for a permit in accordance with Paragraph (b) of this Rule, as well as any site-specific conditions and design requirements stated in the notification; or
(2) the site is deemed unsuitable for establishing an ISWLF unit and the reasons that prevent the ISWLF unit from being operated in accordance with Article 9 of Chapter 130A of the General Statutes, the rules of this Subchapter, and any applicable federal laws and regulations.
(b) When the site has been deemed suitable for an ISWLF unit by the Division in accordance with Subparagraph (a)(1) of this Rule, the permit applicant shall submit to the Division one electronic copy of a permit application, which shall contain the plans described in Paragraphs (d) through (f) of this Rule. A permit for a site shall be based upon a particular type and source of waste, as identified in the operation plan required by Paragraph (e) of this Rule.
(c) The site study shall contain the following information:
(1) An aerial photograph on a scale of at least one inch equals 400 feet showing the area within one-fourth mile of the proposed site's boundaries with the following identified:
(A) entire property owned or leased by the person proposing the site;
(B) land use and zoning;
(C) location of all homes, industrial buildings, public or private utilities, and roads;
(D) location of wells, watercourses, dry runs, and other details regarding the general topography; and
(2) A map on a scale of at least one inch equals 1,000 feet showing the area within two miles of the proposed site's boundaries that identifies known groundwater users, potential or existing sources of groundwater and surface water pollution, water intakes, airports and runways, and subdivisions.
(3) A geological and hydrological study of the site that provides:
(A) soil borings for which the numbers, locations, and depths provide an understanding of the subsurface conditions and groundwater flow regime of the uppermost aquifer at the site.

(vi) remolded sample of cover soils that provide the saturated hydraulic conductivity, total porosity, and atterberg limits;
(B) boring logs;
(C) stratigraphic cross sections identifying hydrogeologic and lithologic units and stabilized water table elevations;
(D) water table information, including:
(i) tabulation of water table elevations at time of boring, 24 hours after boring, and seven days after boring;
(ii) tabulations of stabilized water table elevations over time in order to develop an understanding of seasonal fluctuations in the water table;
(iii) an estimation of the seasonal high water groundwater table, as defined in Rule .0532 of this Section, based on stabilized water table readings, hydrographs of wells in the area, precipitation and other meteorological data, and any other information available; and
(iv) a description of any natural or man-made activities that have the potential for causing water table fluctuations, including tidal variations, river stage changes, flood pool changes of reservoirs, high volume production wells, and injection wells;
(E) a groundwater contour map based on the estimated long-term seasonal high water groundwater table that is superimposed on a topographic map and includes the location of all borings and rock cores and the water table elevations or potentiometric data at each location used to generate the groundwater contours;
(F) a topographic map of the site locating soil borings with horizontal and vertical controls that are tied to a permanent onsite benchmark; and
(G) a report summarizing the geological and hydrological evaluation.
(5) A copy of the franchise or local government approval from each unit of local government in whose jurisdiction the site is located in accordance with G.S 130A-294(b1). No franchise or local government approval shall be required for a site used to dispose of waste generated solely by the permit applicant.
(6) A letter from the unit of government having zoning jurisdiction over the site that states that the proposal meets all of the requirements of the local zoning ordinance, or that the site is not zoned.
(7) A description of how the site complies with the siting standards in Rule .0503(a) of this Section.
(8) A report that includes the following information:
(A) population and area to be served;
(C) the equipment that will be used for operating the site; and
(D) a proposed water quality monitoring plan including surface water sampling locations, well locations, and well schematics showing proposed screened interval, depth, and construction.
(9) Letters from both the State Historic Preservation Office and the Natural Heritage Program within the Department of Natural and Cultural Resources stating whether the proposed use of the property will impact the historic sites described in Rule .0503(a)(2) of this Subchapter; State nature and historic preserves described in Rule .0503(a)(3) of this Subchapter; or the endangered or threatened species described in Rule .0503(a)(4) of this Subchapter located at the site.
