(3) Mine Facilities <br />1. A narrative and maps must be supplied describing all mine <br />facilities which have specific performance standards, the plan <br />for maintenance and the plan for removal must also be supplied <br />for these structures. Maintenance of the recycling ponds and <br />the water treatment facilities are of concern because of probable <br />hydrologic consequences.A'sgthe plan for the removal of the <br />office building is of concern because of post mining land use <br />and estimate of reclamation costs. 2.05.3(3) <br />2. In the permit the applicant must differentiate between those <br />structures which are in existence and which facilities are <br />just proposed. For example, is the coal dryer in existence? <br />How large is the coal refuse pile at this time? 2.05.3(3)(b) <br /> <br />3. Dust suppression on the roads will be controlled by use of <br />calcium chloride. To ascertain the extent of probable hydro- <br />logic consequences the applicant should supply the concentration <br />of the solution, the source of water for dilution and the fre- <br />quency that the solution must be applied. <br />4. The applicant should describe the effects of the leach field <br />on the stability of the road directly above it. (4.03) <br />5. The applicant must state that all structures designated by <br />Geo Testing will be designed and maintained as presented. <br />2.05.3(3)(b)(ii) <br />6. Provisions for monitoring the stability of the refuse pile <br />must be supplied. 2.05.3(3)(b)(ii)(c) and 2.05.6(6) <br />7. A description of each road and conveyor to be construced, used <br />or maintained must be supplied. The description should include <br />a map. A generalized plan for roads is not adequate. 2.05.3(3)(c) <br />(4) Ponds, Impoundments and Diversions <br />The following information is needed for the Division to review <br />the sediment control system. <br />1. A map or maps at a scale of 1" = 100' clearly delineating <br />the location of the sediment ponds, diversion and collection <br />ditches used or proposed to be used for sediment control. They <br />must be located on a topographic map which clearly delineates <br />the watershed boundries for each pond and/or ditch. The extent . <br />of the embankment, the location of spillways, the 10 year, 24 <br />hour storage area, and the location of ditch discharge points <br />must be indicated on these maps. This information is required <br />under Section 4.05.6 to assess pond locations, watershed area <br />calculations and short-circuiting. <br />A. Pond Z Calculations: Pond volume caZculaCion is in- <br />correct. Pond volume =(1.64 in/12/in/ft)(11.35 ac) = 1.55 ac-f t. <br />(5) <br />
