EXHIBIT K <br />Climate <br />The subject site area has a high plain, continental climate. With the mountains to the west, <br />variations in temperature are wide. In the high plains area, rainfall is light and humidity is low. <br />The average frost-free period is 172 days. Annual average precipitation is about 14 inches. <br />In the eastern high plains area, the climate is modified considerably from that expected of a typical <br />high plain because of the nearby mountains to the west. The winds characteristic of the plains are <br />reduced somewhat by the shielding effect of the mountains. <br />Climate data for the Site is assumed to be similar to that of a weather station at Greeley UNC, <br />Colorado. The Western Regional Climate Center tracks temperature extremes and precipitation <br />data for this station. The following table includes data that was collected between March 1, 1967 <br />and April 30, 2009. <br />GREELEY UNC, COLORADO (053553) <br />Period of Record Monthly Climate Summary <br />Period of Record: 3/1/1967 to 4/30/2009 <br />verage Max. <br />verage Min. <br />emperature (F) <br />verage Total <br />Average Total <br />SnowFall (in.) <br />Average Snow <br />Jan Feb Mar <br />[41.5][47]1 [56-1 <br />[15-4][20] 26.8 <br />1 0.481 0.36 l .0E <br />5.911 4.211 7.311 5. <br />1 <br />J?Ju1C <br />84.0 90.0 F8_7 <br />Sep Oct Nov Dec <br />79 66.7 51.2 41.9 <br />24.6 16.5 <br />58.31156.21146.81135-51 <br />65.311 <br />36.01 <br />1.5111 1.3311 1.1211 1.0211 0.7511 0.5011 14.1 <br />0.011 0.011 0.011 0.711 2. <br />111 1 <br />39.91 <br />Percent of possible observations for period of record. <br />Max.
