(a) The Commission may take any appropriate action permitted by law if a section 30(c) applicant does not make a payment required under this subpart. The Commission will not be liable to any fish and wildlife agency for failure to collect any amounts under this subpart.

(b) If the Commission is unable to collect the full amount due by a section 30(c) applicant on behalf of more than one agency, the amount the Commission does collect will be distributed to the agencies on a pro-rata basis except if an agency's cost statement is greater than its most recent estimate to the applicant under § 4.301(b), then the difference between the estimate and the cost statement will not be reimbursed until any amounts owed to other agencies have been paid.
