(Exploration permits, State and Federal mine permits, EPA and NPDES discharge permits, air quality permits.)
Permitting has become critical to a mining company's success. WSMC have completed numerous permits for base metal, precious metal, coal, trona and industrial mineral properties. These permits have included NPDES and EPA Surface and Ground water Discharge Permits, U.S. Army Corps of Engineers 404 Permits, State and Federal Mine Permits, State and Federal Exploration Permits, State Air Quality Permits and numerous other permits required by various city, county, state, and federal governmental agencies. Our managers, engineers, and geologists develop solutions to problems during a project, and maintain constant communication with regulatory agencies to insure timely permit issuance rather than a long and costly re-engineering and negotiation process.

Tenneco Soda Ash Company
|
|
WSMC provided design and permitting services for Tenneco
Soda Ash Company to modify their evaporation pond and increase its
storage capacity. The assignment included the design of two auxiliary
embankments with cementacious grout curtains for seepage control,
a five to six foot downstream raise of the main embankment including
installation of a chimney drain, and the design of two interceptor
trenches and pumpback system. The modification, constructed during
the summer of 1992, added approximately 1300 acre feet of storage
capacity to the facility. The project also included installation
of eight monitor wells around the perimeter of the facility and
five piezometer wells in the embankment.

Mine Permit Amendment and Revision
|
Sweetwater County, Wyoming
|
General Chemical (Soda Ash) Partners
|
|
WSMC prepared an amendment to the Permit to Mine for
an addition of 4800 acres to General Chemical's current underground
mining operation. WSMC provided the necessary text and drawings
required by the Wyoming Department of Environmental Quality-Land
Quality Division. WSMC also completed a revision to the amendment
which was needed for the addition of a ventilation shaft and associated
surface facilities. WSMC was instrumental in negotiating a rapid
approval by the WDEQ to begin construction on the new ventilation
shaft; a very crucial step for continued advancement of the mine.
