Ohio Rev. Code § 3751.09: Issuing abatement orders.

The director of environmental protection may issue orders requiring the owner or operator of a facility where toxic chemicals are manufactured, processed, or otherwise used to abate a violation of this chapter or a rule adopted or order issued under it. The director may issue such orders as final orders without issuing a proposed action under section 3745.07 of the Revised Code and, notwithstanding section 119.06 of the Revised Code, without the necessity to hold any adjudication hearing in connection with any such order. Issuance of an order under this section is not a condition precedent to bringing any civil, criminal, or civil penalty action under this chapter.
