(a) Definition of hazardous materials operations. For the purposes of this subpart, hazardous materials operations means any activity regulated under the Federal hazardous material transportation law, this subchapter or subchapter C of this chapter, or an exemption or special permit, approval, or registration issued under this subchapter or under subchapter C of this chapter.

(b) Failure to pay civil penalty in full. A respondent that fails to pay a hazardous material civil penalty in full within 90 days after the date specified for payment by an order of the Pipeline and Hazardous Materials Safety Administration, Federal Aviation Administration, Federal Motor Carrier Safety Administration, or Federal Railroad Administration is prohibited from conducting hazardous materials operations and shall immediately cease all hazardous materials operations beginning on the next day (i.e., the 91st). The prohibition shall continue until payment of the penalty has been made in full or at the discretion of the agency issuing the order an acceptable payment plan has been arranged.

(c) Civil penalties paid in installments. On a case by case basis, a respondent may be allowed to pay a civil penalty pursuant to a payment plan, which may consist of installment payments.
