information of the reclaimed drainage channel in the Nucla East permit area. <br /> The design of the reclaimed channel at the Nucla Mine is shown in Tab 20, Attachment C. <br /> The major difference between this channel and those at Nucla East is the design method. <br /> The SEDCAD Version 3.0 computer program was used for the redesign of the Nucla postmine <br /> channel. Peak flow and channel geometry were both gained from this program. Typical <br /> input parameters for SEDCAD are shown in Attachment L, Tab 13. The section properties of <br /> the trapezoidal channel are shown in Attachment C. <br /> The reclaimed drainage channels will be topsoiled and revegetated according to Tabs 21 and <br /> 22, respectively. <br /> Slides and Other Damage <br /> Peabody does not anticipate any problems with slides at Nucla Mine during the term of <br /> mining and reclamation activities. Current highwalls at Areas No. 1 and 4 have been <br /> standing since the mine went into temporary cessation in 1983 and have been shown to be <br /> stable. <br /> It is necessary that surface coal mining activities be performed immediately adjacent to <br /> public roads. Presently, a highwall and open pit exist at the fenceline of the <br /> north-south County Road 2650, County Road 124 in front of the former shop area and the <br /> east-west temporary county road north of Area No. 1. In order to reclaim these mining <br /> areas and pits, mining activities will need to be performed adjacent to these roads. <br /> Peabody intends to close portions of these roads to public access when blasting or any <br /> other operations which could create a potential safety hazard occur adjacent to these <br /> areas. If a slide should occur that could have a potential adverse effect on public <br /> property, health, safety or the environment, Peabody will notify the CMLRD by the fastest <br /> available means and comply with remedial measures as approved by the CMLRD. <br /> 20-7 Revised 05/24/91 <br />
