<br />Question a: <br /> <br />Question b: <br /> <br />Question c: <br /> <br />~) <br /> <br />-) <br /> <br />ATTACHMENT 2 <br /> <br />The objective of the proposed project is to <br />beneficially increase the natural precipitation <br />efficiency of winter storms affecting the <br />designated target area. <br /> <br />The target area is the Grand Mesa above 8,000 feet <br />elevation and adj oining mountainous areas above <br />8,000 feet elevation east and southeast of the <br />Grand Mesa. The proposed area is bounded by <br />T11SR97E on the northwest, T13SR97W on the <br />southwest, T12SR94W on the south, T12SR91W, south <br />to T50NR6W, east to T50NR5W, north to T11SR89W <br />(McClure Pass), northwest to T9SR90W on the <br />north, southwest to T11SR92W (Chalk Mt.) and west <br />to T11SR97E. The proposed target area includes <br />portions of Del ta, Mesa and Gunnison Counties, <br />Figure 1 provides a map of this area. <br /> <br />The proj ect will be operated from NAWC I S main <br />office in Salt Lake city, Utah. The licensed <br />meteorologists will have access to all relevant <br />National Weather Service data distributed from <br />suitland, Maryland via geostationary satellite to <br />NAWC I s office through a Zephyr Weather Service. <br />Data includes surface hourly weather observations, <br />upper-air observations, analyzed weather charts, <br />forecast weather charts, and visible and infrared <br />weather satellite imagery. <br /> <br />The program will utilize a network of 10-15 <br />ground based silver iodide generators. These <br />generators will be located at private residences. <br />The local residents will be trained in the <br />operation of these generators. During suitable <br />storm periods the licensed NAWC meteorologists <br />will call these local operators and ask them to <br />operate the generator (either to turn on or turn <br />off the generator). Each generator will be <br />attached to a propane tank. A 2% solution of <br />silver iodide in acetone will be burned in a <br />propane flare resulting in the emission of <br />trill ions of tiny silver iodide particles. The <br />effectiveness of the NAWC generator that will be <br />used is provided in Figure 2 as tested in the <br />Colorado State University cloud simulation <br />laboratory. Each generator will emit 6 grams of <br />silver iodide per hour of operation. <br /> <br />The NAWC meteorologist will determine which <br />qenerator. s if any. should be o];)erated in any <br />particular storm period based upon consideration <br />of wind flows and likely transport over the <br />
