The figures included in Exhibit C show the mine area as well <br />as the access road. <br />Exhibit C.1 shows adjoining surface owners of record as well as the name and location of roads, <br />buildings, structures, wells, drainages, and utilities lines at the site. It also shows structures on <br />the affected land and within 200 feet of the permit boundary. The total area within the permit <br />boundary, referred to as the “Affected Area,” is 364.77 acres. The area to be mined, defined by <br />the “Mining Limits,” is 198.2 acres. The Permit Boundary and Mining Limits areas are based on <br />digital boundaries and legal descriptions provided by Aggregate Industries, Inc. <br />Exhibit C.2 shows current topography reflecting the results of mining and reclamation activities <br />as of April 2021 in the North, Central, and South Quarries. Reclaimed mined areas are identified <br />in green; mined areas subject to future reclamation are identified in yellow. The elevations for <br />completed benches are notated in the South Quarry, to support further discussion and <br />integration into Exhibit D – Mining Plan. <br />Exhibit C.3 shows current topography for the mine access road and supporting structures. <br />Exhibit C.4 shows existing vegetation and land use in the region of the permitted area. <br />Vegetation is generally characterized by extensive grasslands interspersed with widely <br />scattered, isolated clusters of shrubs (Haley & Aldrich 1998).
