(a) The Department of the Interior and State agencies shall cooperate in their efforts to monitor federally licensed or permitted activities described in detail OCS plans to make certain that such activities continue to conform to both federal and State requirements.

(b) If a State agency claims that a person is failing to substantially comply with an approved OCS plan subject to the requirements of this subpart, and such failure allegedly involves the conduct of activities affecting any coastal use or resource in a manner that is not consistent with the approved management program, the State agency shall transmit its claim to the Minerals Management Service region involved. Such claim shall include a description of the specific activity involved and the alleged lack of compliance with the OCS plan, and a request for appropriate remedial action. A copy of the claim shall be sent to the person.

(c) If a person fails to substantially comply with an approved OCS plan, as determined by Minerals Management Service, pursuant to the Outer Continental Shelf Lands Act and applicable regulations, the person shall come into compliance with the approved plan or shall submit an amendment to such plan or a new plan to Minerals Management Service. When satisfied that the person has met the requirements of the OCSLA and this subpart, and the Secretary of the Interior or designee has made the determination required under 30 CFR 250.203(n)(2) or § 250.204(q)(2), as applicable, the Secretary of the Interior or designee shall furnish the State agency with a copy of the amended OCS plan (excluding proprietary information), necessary data and information and consistency certification. Sections 930.82 through 930.84 shall apply to further State agency review of the consistency certification for the amended or new plan.
