The mining industry is faced with a difficult challenge: How do we maximize growth in an increasingly complex and rigorous regulatory environment? With experience ranging from exploration through closure and reclamation at sites throughout North and South America, Africa, Europe, and Asia, E & E will quickly and cost effectively face this challenge. Our staff is expert in the integration of necessary measures to enable mine development, closure, or remediation to proceed in an environmentally acceptable manner.
Burlington Mine Site, Colorado
Received the Colorado Mine Land Reclamation Board's Hardrock Mining Reclamation Project of the Year Award in 2006 for remediating collapse features, closing adits and shafts, relocating a stream, and building and reclaming a mine waste rock repository at an abandoned fluorite mine.
Stephenson-Bennett Mine Investigation, New Mexico
Conducted a comprehensive investigation to define the magnitude and extent of contamination at this abandoned mine, which periodically produced silver, lead, and zinc until 1934. Investigation included characterization of drainage channel network, geometry, and flow paths within the watershed, as well as quantification of volumetric flows and time distributions along the flow paths.
Coeur d'Alene Aquifer and Mining District, Idaho
Tested tailings at seven abandoned mine sites to determine the contribution of their runoff/seepage to water quality degradation in a nearby creek. Evaluated engineering factors and environmental impacts associated with the use of geotextiles in creek construction.
Los Pelambres Copper Mining Company Environmental Management Systems, Chile
Prepared an EIA, assisted with environmental policy for modification of a mechanized pier, and developed monitoring plans. Supervised implementation of a site-procedures manual and general environmental management plans for natural resources, archaeology, protected areas, forested areas, and emergency management operations.
Clayton Silver Mine, Idaho
Remediated tailings that were impacting downstream water quality. Diversion of surface water around tailings was a major part of the selected remediation alternatives.
"The E & E study is very thorough and professional, and the report is well written and well illustrated."—USGC Water Resources Division
E & E/Walsh's branch office in Ecuador was awarded a certificate of official recognition by the Ecuadorian Ministry of Energy and Mines for excellent work in helping petroleum companies comply with environmental regulations.
