Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

• Significant potential environmental risks are associated with extreme natural events and failures in management practices. Extreme natural events (, hurricanes, earthquakes, intense rainfall events, drought) have the potential to lead to the release of contaminants if facilities are not designed and constructed to withstand such events, or fail to perform as designed.
Apr 24, 2017· Granite usually occurs in large deposits, many times referred to as slabs, throughout the world.
