(D) A used or fired military munition is potentially subject to the cleanup requirements of Chapters 3734. and 6111. of the Revised Code if the munition lands off-range and is not promptly rendered safe or retrieved. For purposes of Section 1004(27) of RCRA, a used or fired military munition is a solid waste, and therefore is potentially subject to RCRA corrective action authorities under Section 3004(u), Section 3004(v), and Section 3008(h) of RCRA, or imminent and substantial endangerment authorities under Section 7003 of RCRA, if the munition lands off-range and is not promptly rendered safe or retrieved. Any imminent and substantial threats associated with any remaining material shall be addressed. If remedial action is infeasible, the operator of the range shall maintain a record of the event for as long as any threat remains. The record shall include the type of munition and the location (to the extent the location of the munition is known).
