(2) whether the enforcement of the Plan by each coastal State is satisfactory.
(b) Satisfactory State enforcement
For purposes of subsection (a)(2) of this section, enforcement by a coastal State shall not be considered satisfactory by the Commission if, in its view, the enforcement is being carried out in such a manner that the implementation of the Plan within the coastal waters of the State is being, or will likely be, substantially and adversely affected.
(c) Notification of Secretaries
The Commission shall immediately notify the Secretaries of each negative determination made by it under subsection (a) of this section.
