III. COMMENTS - COMPLIANCE Colowyo C-1981-019 24 Mar 10 c � Pg 1/6 Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. This was a complete inspection of the Colowyo Mine conducted by Jim Stark of CDRMS. The inspection was conducted on 24 and 25 March 2010. Jennifer Sekulski- Barton of CCC accompanied me on both days of the inspection. The weather was cool and overcast and there was snow on the ground from snows the past weekend. Several elevation points were taken during the inspection. The points were taken with a Trimble GeoXT unit. The elevation readings on the GeoXT are not accurate (varying by up to 40 feet) so the units error was checked at a known control point at the site. The point used was station GT-10, which is the mine's primary control, as shown on the Survey Control Map. GT-10 is located at 345837.477N, 1353688.196E (US State Plane 1927, Colorado North, in US Survey Feet) at an elevation of 7389.000 feet (Mean Sea Level, Geoid03). The following chart shows the Divisions readings at GT- 10, including the observed error. The elevation readings on the Trimble GeoXT are approximately 15 feet higher than the actual elevation at GT-10. All elevations listed in this report have been adjusted by subtracting 15 feet from the raw reading.
