MII.TON G. DERRICK MINERAL LAND CONSULTANT GRAND JUNCTION, COLORADO $ISO2 MAILING ADDRESS P, O. BOX 2071 TELEPHONE (970) 2A1-0483 December 8, 2004 Mr. Russ Means Department of Natural Resources Division of Minerals and Geology / 101 South Third Grand Junction, CO 81501 HAND DELIVERED Re: Parkerson C~o~ruction, Inc. / 32 Road Pif,'Mesa County, CO Mineral Extraction Permit 1985-219 v Technical Revision Ol Dear Mr. Means: I ~-1 DEC 1 0 20AS ,function Reid tlfNce ENvfaion of Minerob 8 Geology I submit the following Technical Revision Ol on behalf of Pazkerson Construction, Inc. to address concerns raised by Mr. Mezei of the Army Corps of Engineers regarding irrigation tail water that is directed through Pazkerson's 32 Road Pit, eventually draining into the Colorado River. The proposed T. R. to Permit 1985-219 results from an onsite meeting on October 21S` among Mr. Mezei, Pazkerson representatives and you, and further discussion between Mr. Greg Hoskin and Mr. Mezei, including Mr. Hoskin's letter of October 3`d, a copy which was provided to you. Pazkerson proposes to construct an overflow structure appurtenant to the north end of a small water storage pond situated at the south end of the permit azea, as depicted on the attached drawing. During periods of significant tail water flow, or occasional surface water flow from storm events, water captured by the pond could from time to time overflow into a partially rip rapped dirt channel that will direct the intermittent surface flow to a shallow Swale that will be placed as shown in the attached drawing. The Swale will be part of one or more irrigated fields, and will terminate at the north end of the permit area at the existing tail water channel. In addition, Pazkerson proposes to add additional water to the south shelter belt and plant willows. This will be accomplished next spring.
