If after a hearing, the board makes a finding that a county has failed to comply with a condition or plan approved by the board relating to the requirements of Section 4485.6, the board may require the county to pay an amount equal to the pro rata portion of the principal and interest, paid by the state on bonds the proceeds of which were allocated pursuant to this chapter to the county for the period of noncompliance. The repayment provisions shall not be applicable if the noncompliance with the condition or plan is the result of circumstances beyond the control of the county, or the board finds the county cannot reasonably

comply under the circumstances.
