EROSION CONTROL BY CONTOURING: <br /> Research from the U.S. Environmental Protection Agency (EPA) files and database reveal a June <br /> 4, 2020, Entry Report as to the then status of the mitigation progress for the Camp Bird Mill Tailings Pad. <br /> That report identifies then outstanding projects related to the "historic tailings pile". The current status <br /> however, precipitating this report. is classified as COMPLETED. <br /> 1. Stabilize the downstream historic tailings pile: <br /> 1a Construct a drainage channel along the uphill perimeter of the pile to divert runoff <br /> around the tailings <br /> 1b Excavate the edges of the pile and place this material into the center of the pile <br /> 1c Re-grade the slopes of the pile <br /> 1d Cover the surface of the pile with topsoil <br /> 1e Install erosion control features across the surface of the pile <br /> 2. Stabilize the upstream historic tailings pile: <br /> 2a Re-grade the tailings pile and construct erosion control features <br /> Cover the surface of the pile with topsoil: <br /> 3. Stabilize the stream channels: <br /> 3a Widen and reconstruct Imogene Creek from the pipe bridge downstream to the river <br /> crossing <br /> 3b Remove rock obstructions from Canyon Creek and thin trees on the south bank <br /> 3c Widen and construct Imogene Creek from the river crossing to the confluence <br /> 3d Widen and reconstruct the confluence of Imogene and Sneffels creeks. <br /> 3e Widen and reconstruct Canyon Creek from the confluence to a point of downstream <br /> of the historic tailings.3f Widen and reconstruct Canyon Creek from the confluence to a <br /> point downstream of the historic tailings.3g Armor stream banks and construct erosion <br /> control features.3H Establish vegetation in the constructed floodplain resulting from Site <br /> Visit August 23,2021 <br />
