§ 49.4 Alternative mine rescue capability for special mining conditions. ( a ) If an underground mine is operating under special mining conditions, the operator may provide an alternative mine rescue capability.
( b ) An application for alternative mine rescue capability shall be submitted to the District Manager for the district in which the mine is located for review and approval.

( 4 ) Roadways or other openings are not supported or lined with combustible materials;
( 5 ) The mine shall not have a history of flammable-gas emission or accumulation, and the mined substance shall not have a history associated with flammable or toxic gas problems; and
( 6 ) Any reported gas or oil well or exploratory drill hole shall be plugged to within 100 feet above and below the horizon of the ore body or seam.

( 3 ) The distances from the two nearest mine rescue stations;
( 4 ) The operator's mine fire history;

( e ) A copy of the operator's application shall be posted at the mine. Where a miners' representative has been designated, the operator shall also provide the representative with a copy of the application.
( f ) In determining whether to approve an application for alternative compliance, the District Manager shall consider: ( 1 ) The individual circumstances of the mine operating under special mining conditions;
( 2 ) Comments submitted by, or on behalf of, any affected miner; and
( 3 ) Whether the alternative mine rescue plan provides a suitable rescue capability at the operator's mine.
( g ) Where alternative compliance is approved by MSHA the operator shall adopt the alternative plan and post a copy of the approved plan (with appropriate MSHA mine emergency telephone numbers) at the mine for the miners' information. Where a miners' representative has been designated, the operator shall also provide the representative with a copy of the alternative plan.
( h ) The operator shall notify the District Manager of any changed condition or factor materially affecting information submitted in the application for alternative mine rescue capability.
( i ) ( 1 ) An approved plan for alternative mine rescue capability shall be subject be to revocation or modification by MSHA, where it is determined that a condition or factor has changed which would materially alter the operator's mine rescue capability. If such action is contemplated, the operator will be notified and given an opportunity to be heard before the appropriate District Manager.
( 2 ) If an application for alternative compliance is denied or revoked, the District Manager shall provide the reason for such denial or revocation in writing to the operator.
