<br />Question 1: <br /> <br />Question 2: <br /> <br />Question 3: <br /> <br />~ <br /> <br />r;\234471permil.otl <br /> <br />ATTACHMENT 1 <br /> <br />The objective of the proposed project is to beneficially increase the <br />natural precipitation efficiency of winter storms affecting the <br />designated target area. <br /> <br />Target border runs along the Jackson/Grand County line from <br />Parkview Mountain in T4N, R78W to Cascade Mountain in the NE <br />comer of T4N, R77W, then south along the ridgeline near the R77W <br />and R76W border, to Porphyry Peaks. Then south along the ridgeline <br />to Apiatan Mountain in the NW comer of T3N, R76W. From this <br />'" point, it runs along the ridgeline down to Willow Creek Reservoir and <br />up to the ridge just south of Willow Creek Reservoir in TIN, R76W. <br />From here it travels WNW, following the ridgeline to Elk Mountain in <br />the NW corner of T2N, R78W. From here it runs north through the <br />COITal Peaks in TIN, R78W and on north to Parkview Mountain. <br />Figure 1 provides a map of this area. <br /> <br />The project will be operated from, NA WC's main office in Salt Lake <br />City, Utah. The project meteorologists will have access to all relevant <br />National Weather Service data distributed from Suitland, Maryland, <br />via geostationary satellite and the ID.temet. Data includes surface <br />hourly weather observations, upper-air observations, analyzed weather <br />charts, forecast weather charts, NEXRAD weather radar depictions, <br />and visible and infrared weather satellite imagery. <br /> <br />The program will utilize a network of 15-20 ground based silver iodide <br />generators. These generators will belocated at private residences. The <br />local residents will be trained in the operation of these generators. <br />During suitable storm periods, the licensed NAWC meteorologists will <br />call these local operators and ask them to operate the generator (either <br />to turn on or off the generator). Each generator will be attached to a <br />propane tank. A 2 p~rcent solution of silver iodide in acetone will be <br />burned in a propane flare resulting in the emission of trillions of tiny <br />silver iodide particles. The effectiveness of the NA we generator that <br />will be used is provided in Figure 2 as tested in the Colorado State <br />University cioud simulation laboratory. Each generator will emit <br />approximately eight (8) grams of silver iodide per hour of operation. <br /> <br />The NA WC meteorologists will determine which generators, if any, <br />should be operated in any particular storm period based upon <br />consideration of wind flows and likely transport over the intended <br />target area. Normally not aU generators-will be operated at any given <br />time. <br /> <br />1 <br />
