(a) A State agency shall inform the Federal agency of its concurrence with or objection to the Federal agency's consistency determination at the earliest practicable time, after providing for public participation in the State agency's review of the consistency determination. The Federal agency may presume State agency concurrence if the State agency's response is not received within 60 days from receipt of the Federal agency's consistency determination and supporting information required by § 930.39(a). The 60-day review period begins when the State agency receives the consistency determination and supporting information required by § 930.39(a). If the information required by § 930.39(a) is not included with the determination, the State agency shall notify the Federal agency in writing within 14 days of receiving the determination and supporting information that the 60-day review period has not begun, identify missing information required by § 930.39(a), and that the 60-day review period will begin when the missing information is received by the State agency. If the State agency has not notified the Federal agency that information required by § 930.39(a) is missing within the 14 day notification period, then the 60-day review period shall begin on the date the State agency received the consistency determination and accompanying information. The State agency's determination of whether the information required by § 930.39(a) is complete is not a substantive review of the adequacy of the information provided. Thus, if a Federal agency has submitted a consistency determination and information required by § 930.39(a), then the State agency shall not assert that the 60-day review period has not begun because the information contained in the items required by § 930.39(a) is substantively deficient. The failure to submit information not required by 930.39(a) shall not be a basis for asserting that the 60-day review period has not begun.

(b) State agency concurrence shall not be presumed in cases where the State agency, within the 60-day period, requests an extension of time to review the matter. Federal agencies shall approve one request for an extension period of 15 days or less. In considering whether a longer or additional extension period is appropriate, the Federal agency should consider the magnitude and complexity of the information contained in the consistency determination.

(c) Final Federal agency action shall not be taken sooner than 90 days from the receipt by the State agency of the consistency determination unless the State concurs or concurrence is presumed, pursuant to paragraphs (a) and (b), with the activity, or unless both the Federal agency and the State agency agree to an alternative period.

(d) Time limits on concurrences. A State agency cannot unilaterally place an expiration date on its concurrence. If a State agency believes that an expiration date is necessary, State and Federal agencies may agree to a time limit. If there is no agreement, later phases of, or modifications to, the activity that will have effects not evaluated at the time of the original consistency determination will require either a new consistency determination, a supplemental consistency determination under § 930.46, or a phased review under § 930.36(d) of this subpart.

(e) State processing fees. The Act does not require Federal agencies to pay State processing fees. State agencies shall not assess a Federal agency with a fee to process the Federal agency's consistency determination unless payment of such fees is required by other federal law or otherwise agreed to by the Federal agency and allowed by the Comptroller General of the United States. In no case may a State agency stay the consistency review period or base its objection on the failure of a Federal agency to pay a fee.
