However, the data base is inadequate <br />to rule out the possibility that such a <br />combination might occur." <br /> <br />The objective, as stated in Question 1, is to beneficially' increase <br />precipitation in the target ar~a. If snowpack accumulation reaches a <br />level where additional precipitation would be consfdered to be no <br />longer beneficial, then seeding operations would be either suspended or <br />terminated. The proposed suspension criteria are when the percentage <br />of nomal snowpack. r;eaShes the following values ~. the dates given: <br />,... ." .,:-. - ',.

For December, percent of average shall be <br />ptlculated by the Soil Conservatiori'Service Snow Survey unit.

The purpose of the <br />monitoring/study program will be to 1) establish a "baseline" level of <br />silver present in the snowpack and 2) measure levels of silver in the <br />snowpack immediately after seeding has occured in order to determine <br /> <br />4 <br />
