<br />; <br /> <br /># <br /> <br />2.5.6 Division of Mined Land Reclamation <br /> <br />The Division of Mined Land Reclamation is concerned with flooding as <br />it relates to successful operation and reclamation of mining operations, <br />The interaction of the mining and reclamation operations with surface drainage <br />is considered during the review of mine permit applications, inspections of <br />ongoing operations, and evaluation of final reclamation. The major flood <br />plain problems and potential hazards associated with mining are located primarily <br />in urban areas where gravel is mined along major drainages. Adverse affects <br />of mining on flooding occur less frequently in rural and mountainous areas, <br />due to the sparse population, The Mined Land Reclamation Division, however, is <br />concerned with the re-establishment of stable geomorphic landforms and drainage <br />regimes in all areas of mining. <br /> <br />During the review process or after inspection when a major flood issue <br />arises, the Division may refer the problem to the Water Conservation Board <br />staff for review. Typical problems include the location of large gravel <br />stockpiles or berms related to gravel mining operations within the flood <br />plain and their affect on flooding. <br /> <br />The Division derives its authorities for the minerals program from <br />34-32-101 et~, and for the coal program from 34-33-101 et~, The authorities <br />under the minerals program are quite general with regard to surface drainage <br />control whereas, the coal program authorities are more specific, Under the <br />coal program operators are required to prepare runoff calculations for the volume <br />of water in the 10-year, 24-hour storm and the peak flows for the 25-year, 24- <br />hour storm, <br />
