Dept. of Natural Resources <br />Re: Southeast ; of Section 1, Township 2 North, Range 71 Nest, Leonard and <br />Reino E. Loukonen, 160 acres with legal non-conforming sand stone quarry <br />in Lykins Gulch west of Highway 36 <br />Dear Jim, <br />The above site was conveyed to the Loukonen family in 1940. Initially, <br />approximately 600 tons of rip rap stone were removed and a cutter was installed <br />on the smaller North line 1 acre quarry by 1954. Subsequently, the greatest <br />extraction, 6000 tons, was removed after 1962 from the 5 acre centrally <br />located quarry for the production of National Center for Atmospheric Research <br />aggregate. <br />The continued open mining on the 160 acre parcel preceeded the Special Use <br />permit requirements for such activities as established in 1978. However, <br />the ongoing stone quarrying is governed by the limited impact grading and <br />excavation permit criteria as adopted in 1980. Per visit with Leonard <br />Loukonen, a maximum disturbance area will total approximately 10 acres for <br />which the Mined Land Reclamation Board is encouraged to proceed with the <br />limited impact permit process on the Lykins Gulch Loukonen Quarry without <br />conflict from the local zoning jurisdiction. <br />Sincerely <br />N ~/ <br />/ten /C.,C <br />Thomas J.
