COMMENTS
This was a complete inspection of the Colowyo Mine conducted by Jim Stark of the Colorado Division of
Reclamation,Mining and Safety. The inspection was conducted on 19-22 July 2010. Ryan Pawlowski and
Jennifer Sekulski of Colowyo accompanied me on different portions of the inspection. The weather was warm and
sunny during most of the inspection and the ground was mostly dry. Colowyo did receive rain on the night of 21
July 2010 but that did not create and problems getting around.
AIR RESOURCE PROTECTION—Rule 4.17:
-The South Taylor Haul Road and the haul roads in the West Pit and South Taylor Pit were creating some dust but
Colowyo was actively watering the roads at the time of the inspection.
-Colowyo has applied magnesium chloride to several of the haul roads in the West Pit area to help control dust.

Gullies 4.14.6:
-Colowyo has not completed any additional backfilling and grading at the site since the spring of 2010(around
March 2010).
-Colowyo has completed approximately 90 acres of backfilling and grading in the West Pit. In addition to this 90
acres there is also a block of approximately 35.6 acres that were backfilled and regraded in 2007 and 4.4 acres that
were backfilled and regraded in 2009 that did not have the topsoil replaced. These areas will have the topsoil
replaced and they will be reseeded this year as well. The total acreage in the West Pit that will be topsoiled and
reseeded in 2010 is approximately 130 acres. To date Colowyo has completed approximately 145.7 acres of
backfilling and grading in the West Pit. In the approved backfilling and grading plan(Map 29)Colowyo has
committed to complete 675.8 acres of backfilling and grading by the end of 2012. Based on the amount of
backfilling and grading that has been completed to date, Colowyo will need to complete approximately 530.1 acres
of backfilling and grading in the West Pit in 2011 and 2012.
