Stormwater Control Plan
Logan Wash Mine, Garfield County, Colorado
Western Water & Land prepared a stormwater control plan to address stormwater control measures to be implemented at the Logan Wash Mine as part of final reclamation. The goal of stormwater control at Logan Wash Mine is to minimize hydraulic damage resulting from significant storm events by providing suitable stormwater conveyance structures at the mine to transport water to natural drainages.
The main objective of the routing plan was to control storm runoff that originates on upgradient areas, mine benches, and roads such that high-energy runoff does not cause extensive erosion of these and downslope areas including faces of mine dumps, and outslopes below road cuts. Peak discharge at the mine site was estimated for a selected rainfall intensity event and specifications were prepared for stormwater conveyance structures of appropriate design capacity.
The stormwater control plan focuses on the collection and diversion of storm runoff in channels that convey the water to several main discharge points or outlets. Outlets were designed with the appropriate riprap materials required to sufficiently armor the high velocity outlet features. The plan was submitted to and approved by the Colorado Division of Minerals and Geology as a technical revision to the mine’s reclamation permit.
