Klaus J. Schulz, DeYoung Jr., Robert R. Seal, II, Dwight Bradley, editor(s)
2017, Professional Paper 1802-B
Throughout most of human history, environmental stewardship during mining has not been a priority partly because of the lack of applicable laws and regulations and partly because of ignorance about the effects that mining can have on the environment. In the United States, the National Environmental Policy Act of 1969,...
