-53- During and after mining, the water quantity and quality from the stream section within 100 feet of the surface coal mining operations shall not be adversely affected; and c. Riparian vegetation within the buffer zone shall not be adversely affected. The operation is in compliance with the requirements of this section. XVIII. Bonding - Rules 2.05.4(2)(b) and Rule 3 The applicant has agreed to post a performence bond in the amount of $1,668,500.00. The Division has determined that this amount will be sufficient to cover the cost of reclamation at the mine. Pursuant to rules 2.07.6(2)(j) and 3.02.1(1), the performance bond in this amount will be filed with the Division, payable to the State of Colorado, before a permit will be issued. XIX. The applicant presents plans for sealing drilled holes and underground openings in Sections 2.05.4 and 4.07, Volume 1 of the permit revision application. The portal area of the proposed Foidel Creek mine will be backfilled. Abandonment procedures for the portal area are described in Section 4.14, Volume 1 of the permit revision application. The application is in compliance with this section. XX. Subsidence - Rules 2,05.6(6), 4.20 The applicant has completed an inventory of potentially affected structures and renewable resource lands within the permit and adjacent areas of the proposed Foidel Creek Mine. The inventory is found in Section 2.05.6(6) of the permit revision application. This inventory identified several structures which exist within or adjoining the potentially affected area, including two unoccupied but habitable structures, the CYCC mine office, and portions of County Road No. 27 and a Denver and Rio Grande Western Railroad spur. In addition, the inventory identified renewable resource lands comprised of Foidel Creek and its adjoining surficial alluvium and the Twentymile Sandstone aquifer. The application contains a subsidence prediction, within Exhibit 5a. This projection involves prudent state-of-the-art methods for delineating the potentially affected areas, assuming an angle of draw of 25°. Projection of this angle of draw from the proposed underground workings to the ground surface determined that none of the inventory's structures lie within the potentially affected area, with the exception of the segments of County Road No. 27 and the Denver and Rio Grande Western Railroad spur which pass above the portal entryway mains.
