<br />a) Culverts were located in azeas of preferred or existing drainage. <br />b) Stable road embankments were designed. <br />c) Road grades were not excessive, and <br />d) All haul roads are contained within a sediment control system. <br />Details on culvert sizing and locations are located in Volume 8, Section <br />3.5.3.1. <br />The operation is in compliance with the requirements of this section. <br />B. Access Roads <br />1. Alternative criteria and specifications were used during the design of the <br />Goat Trail access road. The road was designed and constructed prior to <br />August 3, 1977. A variance in reclamation requirements was necessary for <br />the road due to its extreme gradient and steep cut and fill embankments. At <br />the end of the mining, the road will be scarified and seeded only. Additional <br />information is located in Volume 8, Section 3.5.6 (4.03.2(1)(e)). <br />2. The landowner has requested the retention of access roads depicted on Maps <br />No. 3.5-1, Sheets 1 and 2. Skyline Drive, West Ridge Road, and the North <br />Access Road will remain as permanent structures. Skyline Drive provides <br />access to the Routt County landfill and to the D&RGW communication <br />facilities. The North Access and West Ridge Roads are necessary to provide <br />all weather access from county roads to lands within the permit boundary. <br />Their retention is compatible with the approved post mining land use of <br />rangeland. Therefore the Division proposes to approve retention of these <br />access roads (4.03.2(1)(f)). <br />II. Hydrologic Balance -Rule 4.05 <br />A. Water Quality Standards and Effluent Limitations <br />The Division granted small area exemptions from the use of sediment ponds <br />due to the limited size of the azeas and due to the fact that ponds and <br />treatment facilities are not necessary for the drainage to meet the effluent <br />limitations of Rule 4.05.2 and applicable State and Federal water quality <br />standazds for receiving streams and also due to the fact that no mixing of <br />surface drainage with a discharge from underground workings will occur. <br />The small areas exempted aze as follows: <br />a) The south end of the railroad tracks from the permit boundary north <br />to the hopper. <br />Edna Mine IS Pcnnit Renewal No. 3 <br />
