Whether the Clean Water Act prohibited EPA and the Army Corps of Engineers from adopting the Enhanced Coordination Process for Section 404 mining-permit applications.
Holding
No. The Clean Water Act did not expressly or implicitly bar the agencies from consulting and coordinating through the Enhanced Coordination Process.
Reasoning
The process did not alter the statutory standards governing Section 404 permits or reassign either agency’s statutory responsibilities. The Corps still made the final decision whether to issue a permit, and EPA retained its existing authority over disposal sites. The plaintiffs therefore objected not to a change in legal authority, but to greater consultation between two executive agencies.
The court rejected the plaintiffs’ expressio unius argument that Congress’s specification of several EPA roles in Section 404 silently forbade EPA from participating in any other way. Nothing in the Act prohibits consultation between EPA and the Corps, and the court would not infer such a prohibition from silence.
Interagency coordination is ordinary and often valuable within the Executive Branch. Because both agencies are subject to presidential supervision, construing the Clean Water Act to isolate them from each other would conflict with the practical and constitutional premise of a unitary Executive Branch able to coordinate implementation of federal law.
The process also did not violate the Corps’ permit-processing regulation. Although the memorandum contemplated that coordination could exceed the regulation’s 60-day target, that target was aspirational rather than mandatory, and an exception applied when information needed to make a decision could not reasonably be obtained within 60 days.
