Curtail Mining Within the National Forests

A statute gives the Department of the Interior the power to allow or to curtail mining within the national forests “as the best interests of all users of the national forest shall dictate” Is this a valid delegation of legislative power to the agency, or is it too broad a delegation of power? Write a 2page paper (double spaced, 12 point type) which discusses statute, which provided authority to the Department of Interior to allow or to curtail mining within the national forests “as the best interests of all users of the national forest shall dictate,” was or was not a valid delegation of legislative power. In other words, argue both sides!
