(Page 2) MINE ID # OR PROSPECTING ID # M-80-149 INSPECTION DATE 7 31 95 INSPECTOR'S INITIALS ACS OBSERVATIONS The Hokestra Pit permit area (Permit No. M-80-149) is broken up into three areas of activity referred to ae the Hokestra #1 Pit, Hokestra #2, and Hokestra Weet. The Hokestra #1 Pit was permitted November 12, 1980, Hokestra #2 was included into the permit area by amendment approved December 14, 1988, and Hokestra West was included into the permit area by amendment approved April 27, 1993. All three areas are east of I-25, and are bounded by St. Vrain Creek on the north, and County Road 24.5 on the south. The northern portion of Hokestra #1 (north of the Last Chance Ditch) has been reclaimed. Grass is becoming eatabliahed on the berme between the ponds and in the area between the ponds and St. Vrain Creek. A number of trees have been planted throughout the site. Don Carroll indicated that a hiking/biking path may be constructed along St. Vrain Creek. The southern portion of Hokestra #1 (south of the Laet Chance Ditch) was the area being mined until recently, when the operator moved to Hokestra Weet ae will be explained below. Hokestra #2 ie the eastern-moat part of the permit area, and is located north of the Laet Chance Ditch. Hokestra #2 ie mined out and is undergoing reclamation. Gravel extraction during 1995 has focussed on the phases of the Hokestra We9t Pit that are located between the I-25 frontage road and the WYCO pipeline alignment. Weld County received approval to mine this area at this time through approval of a technical revision to the permit approved on November 4, 1994. The reason for the push to extract all of the gravel from this area is the proposed widening of I-25 and changes to the Del Camino interchange. Weld County will be removing the gravel, then backfilling and reclaiming the area to be affected by the freeway improvement project. It is the Division's view that removal of the gravel resource prior to this portion of the permit area becoming part of the I-25 right of way, ie an excellent conservation practice. Once that portion of Hokestra Weet that is going to be affected by the freeway project is mined out and backfilled, the operator will resume mining in the south part of Hokestra #1. Adequate topsoil has been stockpiled southeast of the disturbed area to allow for reclamation in accordance with the approved plan. If freshly stockpiled soil will remain in stockpile for more than one growing season, the pile must be stabilized by seeding with perennial grasses. Ground water has been exposed by gravel extraction activities at the Hokestra Pits. Don Carroll stated that Weld County has obtained a gravel pit well permit for these activities, and that a substitute water supply plan has been approved. Wetlands are being affected by activities in Hokestra Weat Pit. Don Carroll stated that a Department of the Army Permit covering these activities ie in place. cc: Carl Mount, DMG Dick Wolfe D ivieion of Water Resources 1313 Sherman St. Aoom 818 Denver, CO 80203 Mr. Terry McKee Army Corps of Engineers Tri-Lakes Project Office 9307 State Highway 121 Littleton, CO 80123-6901 I & E Contact Address CE NAME Don Carroll ~ BL OPERATOR Weld County Road and Bridge ~ FS STREET P.O.
