Mine Reclamation


WSW continually expands its experience within the challenge of Mine Reclamation projects. WSW has used many proven river restoration and stormwater applications in combination with mine reclamation techniques to achieve success. WSW works with various public and private entities, striving to enhance water quality while creating a more stable and functional system. Most projects consist of a high-level of monitoring before, during and after construction to ensure the site design is functioning properly. WSW is a State of Colorado Certified Industrial Waste Water Operator and works within State Discharge Permits. 


 

WSW Project List: 

Camp Bird Stream Restoration - Mine Reclamation Project, Camp Bird, CO 2017-2018

    WSW asked to design stream restoration portion of EPA Removal Action at Camp Bird    Mine outside Ouray, Colorado. WSW design-building Imogene Creek, Sneffels Creek and Canyon Creek through the historic Camp Bird Mine for Caldera Mining. WSW utilizes natural channel design replicating natural conditions to restore channels and mitigate erosion.

Centennial Mine Reclamation Project, Colorado Dept. of Health and Environment (CDPHE) 2016

   WSW designed a stream restoration project for the CDPHE funded by the Dept. of Natural Resources (DNR) within a steep sloped valley through historic uranium mine tailings from the Centennial Mine, mitigating erosion and enhancing water quality. The WSW design met CDBG Design Guidelines criteria and utilized the Colorado Water Conservation Board’s Topographic Survey of Stream Channels. The site within Disappointment Valley is a historic area of tailings storage with an actively eroding channel through the center. The effort is to create a stable ephemeral channel to mitigate downstream transport and aggradation of tailings.

Sun Cup Mine Reclamation Project, Colorado Dept. of Health and Environment (CDPHE) 2016

   WSW asked by the CDPHE funded by the Dept. of Natural Resources (DNR) to design a stream restoration project within a meandering valley through historic uranium mine tailings. . The resulting WSW design met CDBG Design Guidelines criteria and utilized the Colorado Water Conservation Board’s Topographic Survey of Stream Channels. The site within Disappointment Valley is a historic area of tailings storage from the Sun Cup Mine with an actively eroding, meandering channel through the tailings pile. The effort is to create a stable ephemeral channel, by mitigating erosion and the downstream transport and aggradation of tailings, and to optimally enhance long term water quality.

 

Silverbell Mine Reclamation, PacifiCorp, Ames, Colorado, 1999-2017

WSW has acted as Operator in Charge (OIC), managing data collection and operation of Silverbell Mine Reclamation Project for almost seventeen years. WSW in collaboration with MWH and recently AEC, design-builds iron retention ponds, and limestone bays for pH alteration to encourage deposition of iron for compliance of CDPHE permit standards. WSW design builds treatment wetlands to further mitigate and buffer acid mine drainage into the Howard’s Fork of the San Miguel River. The experience of continually improving this Good Samaritan project with PacifiCorp has provided opportunities for WSW to combine stream restoration and mine reclamation techniques. The project requires WSW to be a State Certified Industrial Waste Water Operator.

Ouray Silver Mining Company, Ouray, Colorado 2015

   WSW consulted on hydrologic techniques, data collection and compliance procedures within State of Colorado discharge permit. Collected hydrologic data both underground and on surface.

Silverbell Mine Reclamation Treatment Wetland Project, Ames, Colorado, 2008

WSW field implementeddesign and managed construction of retention pond, limestone bays for pH alteration to encourage deposition of iron, and treatment wetlands to mitigate acid mine drainage in collaboration with MWH and Skanska Construction. Recycled alluvium from stream project to pond and installed wetland vegetation.

Silverbell Mine Reclamation, PacifiCorp Inc., Ames, Colorado, 2006-2007

WSW acquired U.S. Army Corps permit,designed and built stream bank stabilization-vane arm construction to protect mine tailing retaining wall, involved lowering boulders with 100’ cable and long reach excavator over 150’ cliff.  Utilized stream restoration techniques to protect toe of mine reclamation project. Transferring skills from diverse environmental projects also created opportunity to use alluvium from stream flood mitigation on treatment wetland berm improvements. Implemented storm water management and BMP’s.
