Hopefully, this <br />will resolve all outstanding issues so an approval decision can be made by June 7, 1991. <br />Section 1.0 - 1990 Annual Reclamation Report <br />This section was acceptable to the Division. <br />Section 2.0 -Annual Hydrology Report <br />Trapper has updated page 4-247a and Table 4.8-13a (pgs 4-247b, 4-247c, and 4-247d) to reflect recom- <br />mended changes by the Division. Trapper understands that if future impacts become significant, monitoring <br />on a quarterly basis may be required again. Additionally, continued consistency of water quality sampling <br />parameters at other well sites may constitute further reductions to biannual sampling requirements. <br />In review of the Division's comments and recommendations for sampling frequency, the Cottonwood Spring <br />well was not addressed by the Division. Trapper will assume the Division has approved our original <br />biannual sampling request unless otherwise notified. <br />Section 3.0 -Drainage Reconstruction, Improvements and Repairs (1990) <br />This section was acceptable to the Division. <br />Section 4.0 -Regraded Spoil Sampling <br />This section was acceptable to the Division. Trapper will visually monitor the vegetation response on the <br />isolated spoil area where a low PH value was reported. <br />Section 5.0 -Topsoil Stockpile Locations (1990) <br />This section was acceptable to [he Division. Additionally, Trapper encourages the Division's inspection of <br />topsoil stockpile locations to ensure proper reporting. <br />Section 6.0 <br />This section was acceptable to the Division. Minor deficiencies still etdst on two stock ponds constructed <br />during 1990. First, erosion control matting installed within the spillway of the Colt pit pond (SCS corre- <br />spondence 926/90 #5) needs completed. Additionally, the lower pond in the upper Johnson Gulch tribu- <br />taries needs to have the upstream embankment [oe flattened to a 3:1 slope (SCS correspondence 1121N0 <br />P.0.f3ox 187 Craig, Colorado 81626 (303) 824-4401 <br />
