"Mining companies and other businesses will be allowed to keep environmental studies secret, even if they detail possible pollution problems, under industry-backed legislation that gained final House approval Monday."

But the legislation does not provide outright immunity. Businesses still would be subject to sanctions for environmental violations spotted by regulators. And the new legal privilege would not apply in criminal cases."
