A permit revision request shall be subject to the
notice requirements of §
86.31 (relating to public notices
of filing of permit applications) under the following circumstances:
(1) For surface mining activities:
(i) Discharging to a different watershed not
previously receiving a discharge from the operation or a change in water
handling procedure. Water handling includes, but is not limited to, treatment
facility design or use of other treatment techniques not identified by the EPA
as Best Available Technology Economically Achievable (BAT) in 40 CFR Part
434
(relating to coal mining point source Category BPT, BAT, BCT limitations and
new source performance standards) and additional discharge points.
(ii) The addition of auger mining to the
operation.
(iii) The addition of
coal refuse disposal, beneficial use of coal ash or biosolids, or residential
septage for land reclamation to the operation.
(iv) The change of postmining land
use.
(v) A physical change in the
mine configuration is proposed. Physical changes include, but are not limited
to, stream diversion structures, new or expanded road systems and elimination
of public roads.
(vi) The addition
of blasting to the operation.
(2) For underground mining activities:
(i) Discharging to a different watershed not
previously receiving a discharge from the operation or a change in the water
handling procedure. Water handling includes, but is not limited to, treatment
facility design, or use of other treatment technologies not identified by the
EPA as BAT in 40 CFR Part
434 and additional discharge points.
(ii) A physical change in the mine
configuration is proposed. Physical changes include, but are not limited to,
stream diversion structures, new or expanded road systems, elimination of
public roads, new mine openings excluding boreholes and acreage
modifications.
(iii) A change to
the postmining land use or subsidence control plan is proposed.
(3) For coal refuse disposal
activities:
(i) Discharging to a different
watershed not previously receiving a discharge from the operation or a change
in the water handling procedure. Water handling includes, but is not limited
to, treatment facility design, or use of other treatment technologies not
identified by the EPA as BAT in 40 CFR Part
434 and additional discharge
points.
(ii) A physical change in
the coal refuse disposal configuration which is proposed. Physical changes
include, but are not limited to, stream diversion structures, new or expanded
road systems-except roads on the fill-elimination of public roads, new disposal
areas and acreage modifications.
(iii) A change in the postmining land use.
