This bill aims to restrict federal authority over hunting and fishing equipment by generally prohibiting the Secretary of the Interior and the Secretary of Agriculture from banning the use of lead ammunition or tackle. This restriction applies to federal lands and waters under their jurisdiction that are made available for hunting or fishing activities. Furthermore, it prevents these Secretaries from issuing new regulations specifically concerning the level of lead in ammunition or tackle used in these areas, intending to maintain current access for recreational users. An important exception to this general prohibition exists for specific, localized areas. A prohibition or regulation on lead use may be implemented if the relevant Secretary determines that a decline in wildlife population at that specific unit of federal land or water is primarily caused by the use of lead, based on field data from that unit. Additionally, any such localized restriction must be consistent with State law , an applicable policy of the State's fish and wildlife department, or explicitly approved by that State department. The bill requires a Federal Register notice to explain how any such prohibition meets these specific requirements.
