Universal Citation: MT Admin Rules 17.24.188
Current through Register Vol. 6, March 22, 2024
(1) An application for a small miner cyanide or other metal leaching solvent or reagent ore processing permit must contain a reclamation plan that includes the following:
(a) the postmine land use;
(b) a reclamation timetable;
(c) the proposed method for handling spent
ore and disposal of any heavy metal sludge remaining in ponds;
(d) a plan for monitoring water balance for
the ore processing facility;
(e) a
neutralization plan for tailing and solutions;
(f) a map showing regrading plans for all
cyanide or other metal leaching solvent or reagent-processing and related
facilities to a stable, minimally erosive slope configuration by backfilling
excavated material, consistent with the postmining land use;
(g) a narrative providing for reclamation of
all buildings and structures;
(h) a
plan for reclaiming all associated roads, or an appropriate waiver from the
surface owner;
(i) a revegetation
plan including seed mixes, method of seeding and rate of seed application
(lbs/ac) ;
(j) a description of any
permanent diversion or stream channel reconstruction process, including use of
coarse noncyanidated, nonmineralized tails or borrow material to dissipate
energy or riprap streams, or use of synthetic erosion control and revegetation
fabrics. Streams must be reconstructed with comparable grades, pools, and
meanders to premine drainage;
(k) a
plan for stream channel reconstruction providing that the channel may not be
reconstructed through reclaimed tails; and addressing control of drainage from
the tails and the adjacent areas to maximize the long-term stability of the
tails; and
(l) monitoring plans for
reclaimed sites.
(2) In addition, a processing facility which would constitute a "project", as that term is defined in 75-7-103, MCA, on a perennial stream, must comply with the requirements of the Natural Streambed and Land Preservation Act, as amended, by obtaining permits required by the appropriate conservation district.
