conveyance, and the degree to which the coal is crushed and conditioned.
10.13.1.1 Fire Hydrants. Adequate fire hydrant protection shall be provided
for all coal piles. Consideration should be given to the long term methods of
coal pile storage to minimize spontaneous combustion. Fires are generally
extinguished by moving coal and compacting, but hosing smoldering heaps may be
10.13.1.2 Coal Bins. Coal bins or bunkers will require temperature and/or CO
monitoring for hot areas which may be conducive to spontaneous combustion.
10.13.1.3 Conveyers. Conveyer systems shall be of noncombustible
construction and noncombustible conveyor belts should be used. These systems
shall be designed to minimize the chances for the accumulation of coal dust.
10.13.1.4 Feed Systems. The feed systems from storage areas shall be
