RE: Review of McClane Cany""one/ M6i~ne Permit Application:
Geology, Ground Water, and Surface Water
I have noticed several areas of concern during my review of the McClane Canyon
Mine permit application. These concerns should be handled as stipulations to
the permit- The following materials are in the form of proposed justifications
for stipulations and stipulations to the permit.
Geology (Analyses of Roof, Floor, Interburden, and Coal) Rule 2.04.6(2)
Only a partial analysis of the Cameo coal seam was included in the permit appli-
cation. The applicant has not provided analyses of the interburden and floor
materials. At present, the only potentially toxic, acidic, saline or alkaline
material exposed to atmospheric weathering and leaching is the coal. The coal
is exposed in an open stockpile on the mine bench. Without a complete chemical
analysis of the coal, an assessment cannot be made of the hydrologic impacts
of the coal stockpile. Therefore, the following stipulation is required by
the Division to find the applicant in conformance with 2.05.6(3):
Sheridan Enterprises, Inc. must analyze the run of the mine coal,
contained in the coal stockpile for the parameters contained in Appendix
A, Baseline Overburden Chemical-Mineral Analysis. This analysis
shall be submitted to the Division within 60 days following the issuance
of the permit.
Since the present mine is dry and since presently no waste rock or coal processing
waste are generated during the mining operation, no analysis of interburden
and floor rock will be required of the applicant by the Division. The roof
material consists of 8 to 11 feet of Cameo coal and an analysis of the coal will
satisfy this requirement. Other mines which mine the Cameo seam, however, gen-
erate both waste rock and coal processing waste and have to discharge water
from their mines. Should the applicant either experience mine inflows, or have
to dispose of waste rock or coal processing waste in a surface pile, the appli-
cant must provide to the Division an analysis of the interburden and floor
materials to assess the impacts of these materials on ground and surface water
quality. The following stipulation is, therefore, placed upon the permit to find
the applicant in compliance with 2.04.6(2) and 2.05.6(3):
