The outby SCSR storage plan shall also show how the storage location(s) in the primary and alternate escapeways was determined. The District Manager may require the mine operator to demonstrate that the location, quantity, and type of the additional SCSRs provide protection to all persons to safely evacuate the mine. The outby SCSR storage plan shall be kept current by the mine operator and made available for inspection by an authorized representative of the Secretary and by the miners' representative.
