On October 26, the CLC submitted comments on the Office of Surface Mining’s proposed Stream Protection Rule on behalf of the Hoosier Environmental Council. The proposed rule updates surface coal mining regulations in light of new information on coal mining’s effects on ecosystems and the difficulty of replacing healthy streams impacted by mining. The proposed rule would allow companies to mine through streams if avoiding the streams is not practicable and the applicant demonstrates that she can replace the form and function of the impacted stream. However, the rule allows states with primary authority over surface coal mining to develop their own standards to measure stream function.
