If, after judicial review, in a case where the escrow account requirement has been waived, and in cases where a bond has been posted in lieu of such requirement, the court affirms, in whole or in part, the assessment of a civil administrative penalty, the commission shall be paid the amount thereof together with interest at the rate provided in section 6C of chapter 231. If, after judicial review in a case where an interest-bearing escrow account has been established, the court affirms the assessment of such penalty, in whole or in part, the commission shall be paid the amount thereof together with the accumulated interest in the interest-bearing escrow account. If the court sets aside the assessment of a civil administrative penalty in a case where the amount of such penalty has been deposited in an interest-bearing escrow account, the operator on whom the civil administrative penalty was assessed shall be repaid the amount so set aside, together with the accumulated interest thereon.
