EACH POND CLEANOUT EPISODE. REQUIRED PARAMETERS WILL INCLUDE
THOSE LISTED IN 4.06.2(4)(a), WITH THE EXCEPTION OF THICKNESS, DEPTH,
COARSE FRAGMENTS, AND AREAL EXTENT. ANALYSES FOR SELENIUM,
BORON, NITROGEN AND ORGANIC MATTER WILL BE INCLUDED IN ADDITION
TO THOSE LISTED. POND CLEANOUT MATERIAL, WILL NOT BE PLACED IN THE
TOPSOIL STOCKPILE OR USED AS FINAL RECLAMATION TOPDRESSING PRIOR
TO OBTAII~IING WRITTEN APPROVAL FROM THE DMSION.
Surface soils will be sampled and analyzed for fertility levels upon completion of fmal grading
and topdressing. If soil is found to be phosphorus deficient, phosphorus fertilizer will be
incorporated into the soil prior to seeding. Other elements if deficient will be added to the soil the
following yeaz.
The following specific fmding is required by Rule 4.
The Division has determined selected overburden materials shall be used for, or as a
supplement to topsoil. The resulting soil is equal to or better than the available topsoil. This
determination is based on physical and chemical analyses approved by the Division
(4.06.2(4)(a)). This finding applies to overburden material on the mine bench and haul road
outslopes where no topsoil was salvaged prior to disturbance, and also applies to sediment
pond cleanout material, subject to the demonstration specified in Stipulation No. 27.
N. SEALING OF DRILLED HOLES AND UNDERGROUND OPENINGS
The Division will require that each hole, well or other underground opening be capped, sealed,
backfilled, or otherwise properly managed, in accordance with Rule 4.07.3. The application
includes portal seal designs (Figures 3.7-1 and 3.7-2) which depict a keyed in concrete block seal a
minimum of 25 feet in from the portal opening, which would be backfilled with incombustible
material. This design meets the applicable MSHA requirements at 30 CFR 75.1711.
V. COAL MINE WASTE
Coal mine waste in the form of coal fines scraped up from the coal yard area, high ash coal that
cannot be blended and shipped, and coaly sediment from the cleanout of ditches, sediment traps
and the sediment pond will be disposed of in an approved permanent coal mine waste disposal site
in the adjacent Munger Canyon permit azea (Permit No: C-81-020). The Munger Canyon Mine is
also operated by CAM. Detailed construction and reclamation designs for the coal waste disposal
site were approved by the Division pursuant to Technical Revision 14 (TR-14) to the Munger
Canyon Mine permit, in November 2002. Specific fmdings pursuant to Rule 4.10.1(2), allowing
for disposal of waste material from sources outside of the permit area are included in the approved
permit for the Munger Canyon Mine. Development work was completed in the fall of 2004 and
initial waste disposal at the Munger Canyon disposal site occurred in late November 2004.
Several small temporary coal waste stockpiles are approved in the vicinity of the product coal
stockpile at McClane. There is also an approved sediment drying area stockpile near the McClane
sediment pond. Material from these stockpile locations will be periodically hauled to the
permanent disposal site in the Munger Canyon permit area.
The McClane Canyon application also notes that rock slope material will be disposed of in azeas
of the mine that are no longer actively producing coal, as authorized by MSHA. As noted on page
