XV, Operations Description - Rules 2.05.2, 2.05.3(1), 2.05.3(2) and 4.01
Information pertaining to the description of the operations plan is presented
in Volume 9, Tab 12.
Strip mining activities were performed utilizing two 5-yard draglines until
1983 when the Nuc1a Mine temporarily ceased operations following closure of
the Colorado-Ute Nucla Generating Station for reconstruction. As part of the
Permit Revision No. 1 application, Peabody changed this mining method from
draglines to scrapers and dozers,
Mining operations to be conducted in year 1988 will occur in four different
areas as depicted on Exhibit 12-1 "Operations Plan" and as addressed below.
1. Mine Area No. 1 is located in the S 1/2 SW 1/4 of Section 25, T47N R16W
and approximately 2,500 feet northwest of the former mine office. Both
the Upper and Lower Dakota coal seams will be mined and maximum
overburden depth will approach 60 feet. Mining in this area is scheduled
to occur throughout 1988.
2, Mine Area 2 is located in the NE 1/4 of Section 36, T47N R16W in an area
previously mined and reclaimed under the interim permit 75-36. Only the
Lower pakota coal seam remains to be mined with overburden depths
approaching 20 feet. Mining is scheduled to occur from January through
June, 1988.
3. Mine Area No. 3 is an area previously mined similar to Mine Area 2.
Mining is slated to occur from June through December, 1988.
4. Mine Area 4 is the former shop area located in S 1/2 SE 1/4 of Section
25, T47N R16W adjacent to the Montrose and San Miguel County landfill,
Both coal seams will be removed with overburden depth approaching 40
feet. Excavation in this area began during the latter part of December,
1986 and ceased in February, 1988. Reclamation in this area is being
delayed to allow for review of an application to convert the post mining
land use from rangeland to industrial/commercial. Peabody has submitted
Technical Revision No. 2 (received on March 10, 1988) to change the post
mining land use based upon a request from the landowner, San Miguel and
Montrose Counties, to use this area as a sanitary landfill. Current
sanitary landfill activities are occurring just north of this area in an
approved location. Upon approval of this change in post mining land use,
this area will be used by the counties as a sanitary landfill under the
regulations of the Colorado Department of Health.
The above mentioned timeframes mAy vary depending upon contractual demands and
coal shipment to the Nucla Generating Station.
Peabody proposes to mine approximately 32.9 acres in these four mine areas
yielding 311,750 tons of coal and requiring the displacement of about
2,061,900 cubic yards of overburden and parting material. The mined coal will
be hauled by an independent contractor to the Nucla Generating Station.
The operation is in compliance with the requirements of this section,
