Using the Sun to Power Environmental Cleanup at the Pennsylvania Mine
EPA is using the sun to power cleanup work at the Pennsylvania Mine above Keystone, Colorado. In an effort to reduce the amount of toxic metals flowing into Peru Creek, a tributary to the Snake River, EPA is performing work to stabilize and prevent erosion of mine waste at the mine as well as supporting the Colorado Division of Reclamation, Mining & Safety in plugging mine tunnels to decrease the flow of metals-contaminated water. Usually this type of field operation involves running a diesel generator continuously to power and recharge tools, sampling devices, communication equipment and computers. At the Penn Mine EPA is using a solar powered generator with battery backup.
