The following is a quote of <br />the full ABSTRACT from an article taken from the <br />Journal of Applied Meteorology, Vol. II, Decem- <br />.ber 1972: <br /> <br />, ~" <br /> <br />"Estimates based on information.in medical and <br />meteorological literature indicate that silver <br />iodide in the air and in precipitation does not <br />pose a danger to people in the target area. Al- <br />though the concentration of AgI near the genera- <br />tor is much larger, interviews with operators who <br />have been seeding on a large scale for many years <br />fail to disclose any instances of ill effects <br />from AgI." <br /> <br />Based on the experience of WRDC iu this area, <br />there will be no significant effects on-the envir- <br />onment because of cloudseeding. <br /> <br />G.At the present time we aren't aware of any other cOn- <br />templated weather modification projects in western <br />Colorado. <br /> <br />We are very willing' and would solicit complete coop- <br />eration with the operators of any weather modifica- <br />tion programs that may be established in Colorado. <br /> <br />H. The Grand Mesa cloudseeding program, which has been <br />operated by WRDC for many years, is designed to mini- <br />mize risk (see Item F above) and to maximize economic <br />benefits (see Items A and B above) for the people of <br />the Grand.Mesa area. <br />
