Assurance is needed that all water <br />use3 in the mining operation stays on the excavation site and that there is no dumping of water <br />down gradient. The Rock Creek azea is considered a very unique habitat for numerous species. <br />The: uniqueness and diversity of habitats in Rock Creek are not found elsewhere in the area. <br />Information supplied to date from WAI is insufficient in detailing how WAI intends to preclude <br />
