Recently, the DC Circuit decided the case of National Mining Association v. McCarthy. Reversing the lower court, the court held that an "Enhanced Coordination Process" memo and guidance authored by EPA and the Corps of Engineers to coordinate their joint review of coal mining Clean Water Act, 33 U.S.C. §§ 1251, et seq. ("CWA"), water discharge permits was only a procedural rule and not a "final action" subject to review under the APA. The Court of Appeals concludes that the memo only enhances these agencies' ability to coordinate the application of their duties under the CWA, and does not change their substantive statutory responsibilities.
