Notwithstanding any other provision of the Revised Code that limits the time within which an action shall be commenced, a cause of action for personal injury or real property damage resulting from a civil violation of the hazardous waste provisions of this chapter shall not be deemed to have accrued or arisen until the plaintiff discovers or reasonably should have discovered the injuries or damage, provided that this section shall not be construed to affect in any way causes of action that might otherwise be deemed to accrue or arise as a direct or proximate result of acts performed or omitted on or before October 9, 1980, regardless of the date that suit upon those causes of action is commenced or tried.
