This survey is required by Section 4.8.5.2a of the permit. <br />Results of the 1990 survey revealed no spoil springs that meet the 5 gpm criteria (second <br />consecutive year). In 1988 only one spoil spring (Cottonwood} exceeded the 5 gpm cri- <br />teria. However, due to lower-than-normal precipitation in 1989 and 1990, even the <br />Cottonwood spring flowed c5 gpm. <br />2.8 Monitoring Well Abandonment <br />Wells GA-3, GA-4 and GA-5 were not abandoned in 1990 (TR48 approved Aug. 14, <br />1990); however, they will be abandoned in 1991 in accordance with Colorado regulation <br />4.07.3(2,3) and previously approved abandonment procedures specified in TR32 (1987). <br />2.9 Proposed Hydrological Monitoring Frequency Reduction for 1991. <br />Trapper proposes to reduce the frequenry of sampling for several groundwater wells <br />currently being sampled on a quarterly basis. Trapper proposes bi-annual sampling <br />(spring and fall) for the following wells: <br />GAl, GA2, GB2, GBS, GD1, GD2, GD3, GEl, GE2, GE3, GFl, GF2, GF3, GFS, GF6, <br />GFl 1, J1, P1, P3, P5, P8, 81-03A, GP3, GP4, GPS, GP6, and Cottonwood Spring. <br />
