iJuly 15, 2010 7W?Z- RECEIVED Mr. Eric Scott, PG JUL 2 2 2010 Environmental Protection Specialist Division of Reclamation, Colorado Division of Reclamation, Mining and Safety (DRMS) Mining & Safety 1313 Sherman Street, Room 215 Denver, CO 80203 RE: Jake Kauffman & Son, Inc. Request for Technical Revision (TR) to Wagner/Kauffman Pit #3, M-1999-069, Larimer County, Colorado for Proposed City of Loveland Boyd Lake Avenue Extension Eric: Pursuant to previous informal inquiries and discussions over the past year's time, please find attached information and materials detailing a formal request for a Technical Revision (TR) to the 112 Regular Operations Permit M-1999-069, held by Jake Kauffman & Son, Inc. This Permit is for mining sand and gravel aggregate materials in Larimer County, Colorado. We appreciate your patience and availability for consultation while the final agreements for this change have been put in place, and these informational materials have been developed. Generally, this TR is being requested to allow for construction of a roadway embankment for a portion of the proposed future extension of Boyd Lake Avenue through the subject mining pit. The roadway embankment construction is proposed to roughly bisect the permit property, as illustrated in the attached, revised Exhibit F Reclamation Plan map. This embankment will encroach upon the proposed reclaimed "East Reservoir", cutting off the approximately 10 acre northwest comer of this reservoir. This will change the proposed reclamation and after- use of the property. The City of Loveland has officially purchased the actual road right-of-way property, as illustrated on the attached, updated Exhibit O Property Ownership map. I have also attached a new Right of Entry authorization letter from the City of Loveland to update the Exhibit N Right of Entry for the Permit. The authorization letter grants Jake Kauffman & Son, Inc., as the Permit holder, mine operator and party responsible for final reclamation, the right to enter the property to conduct activities in conformance with the approved Mining and Reclamation Plans, including this TR request. The identified roadway embankment area will be filled in years 2010-2011, covered with topsoil, and revegetated as pasture ground until such time as the City of Loveland commences final construction of the road. The remaining road construction will include paving among other final improvements, and is not expected to take place until well after final reclamation of the pit, including the roadway embankment, and the related final release of the reclamation bond.
