Green Tier Application Raises Ire of Conservation Lobby
Could be a great way for frac sand mining operations to change public perceptions about environmental concerns. Get high marks from state regulators for environmental performance. It's what Smart Sand in Oakdale is trying. Aiming for Green Tier status in Wisconsin. A travesty, says Anne Sayers with the Wisconsin League of Conservation Voters
The DNR has apparently received more public comments on Smart Sands Green Tier application than any other request in the program's ten year existence.
