For purposes of sections 25200.10 and 25187 of the Health and Safety Code, a used or fired military munition is a waste, and, therefore, is potentially subject to corrective action authorities under sections 25200.10 and 25187 of the Health and Safety Code if the munition lands off-range and is not promptly rendered safe and/or retrieved. Any imminent and substantial threats associated with any remaining material shall be addressed. If a 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 its location (to the extent the location is known). For the purposes of this section, the term “military munitions” is as defined in 40 Code of Federal Regulations section 260.10. The requirements of this section apply only to military munitions that are regulated under the federal act, as defined in Health and Safety Code section 25115.1.
