During Permit Renewal RN-07 the division requested a continuation of several climatological datasets <br /> for the Trapper Mine. These tables and figures have been updated with data collected at Trapper via <br /> the National Weather Service Cooperative Observer Program station (CRAIG 4SW)established at the <br /> Trapper Mine office in May of 1977. Daily temperature data and 24 hour precipitation amounts, <br /> including snowfall are collected at this site. <br /> Other meteorological information has been collected in the area at the Craig-Moffat Airport located <br /> near the Yampa River south of Craig,Colorado. This station consists of an Automated Surface <br /> Observation Station (ASOS)operated by the NWS, FAA and DOD. Observations at this site are similar to <br /> observations taken of the CRAIG 4SW, however,elevation and topographical attributes of the site do <br /> cause differences between the data sets. Because of these differences,only data collected at CRAIG <br /> 4SW has been used to update this section, as they are more relevant to the site conditions of the mine <br /> site. <br /> During the period of March 2015 to March 2016 a meteorological tower was operated by Trapper and <br /> Air Resource Specialists adjacent to the Kimber Pit area at the East Panel Ready-line to gather <br /> meteorological data for air permit modeling at the site. Wind data has been used from this station to <br /> compare to the baseline wind data taken by Stearns-Roger at the mine site office. The annual wind data <br /> collected at this site has been presented as Figure 2.1-3a in this section. <br /> Tables 2.1-1a, 2.1-2a, 2.1-4a, 2.1-6a and 2.1-8a included in this section contain weather data from COOP <br /> Station CRAIG 4SW and provide updated information. Each table represents a continuation of their <br /> companion table with the CRAIG 4SW dataset for the period of 1978 to the most recent available data as <br /> of 2017. <br /> Aside from the large difference in long term precipitation recorded at the Craig weather site from 1936 <br /> to 1977 versus CRAIG 4SW, most values mimic the previous records and compliment them in regard to <br /> the long term climate in the Craig area. The difference in precipitation can be correlated to the drop in <br /> elevation between the prior Craig site and CRAIG 4SW site located at Trapper Mine. <br /> 2-2a <br /> Revision: RN-0 7 <br /> Approved: <br />
