Federal and State agencies shall cooperate in their efforts to monitor federal assistance activities in order to make certain that such activities continue to conform to both federal and State requirements.

The State agency shall notify the relevant Federal agency representative for the area involved of any federal assistance activity which the State agency claims was:

Previously determined to be consistent with the management program, but which the State agency later maintains is being conducted or is having an effect on any coastal use or resource substantially different than originally described and, as a result, is no longer consistent with the management program, or

Previously determined not to be a project affecting any coastal use or resource, but which the State agency later maintains is being conducted or is having an effect on any coastal use or resource substantially different than originally described and, as a result the project affects a coastal use or resource in a manner inconsistent with the management program.

The State agency notification shall include:

A description of the activity involved and the alleged lack of compliance with the management program;

supporting information; and

a request for appropriate remedial action. A copy of the request shall be sent to the applicant agency and the Director.

If, after 30 days following a request for remedial action, the State agency still maintains that the applicant agency is failing to comply substantially with the management program, the State agency may file a written objection with the Director. If the Director finds that the applicant agency is conducting an activity that is substantially different from the approved activity, the State agency may reinitiate its review of the activity, or the applicant agency may conduct the activity as it was originally approved.

An applicant agency shall be found to be conducting an activity substantially different from the approved activity if the State agency claims and the Director finds that the activity affects any coastal use or resource substantially different than originally determined by the State agency and, as a result, the activity is no longer being conducted in a manner consistent with the management program. The Director may make a finding that an applicant agency is conducting an activity substantially different from the approved activity only after providing a reasonable opportunity for the applicant agency and the Federal agency to review the State agency's objection and to submit comments for the Director's consideration.
