' ~~~ <br /> <br />State of Colorado <br />Mined Land Reclamation <br />September 20, 1978 <br />Page 2 <br />I was very disappointed with the poor quality of the re- <br />duced reproduction of the Concrete Quarry property on map <br />pcc-1395 overlays used for Exhibits Cc and Fc and drafting <br />personnel was not available for retracing these older, poor <br />quality tracings. Ideal will be doing exploration work in <br />this area in the near future for which new maps will be re- <br />quired. <br />Attached is a cross-section sketch looking northward from <br />the east-west coordinate 109,000 (near the middle of Cut #2) <br />which gives a better indication of Beaver Creek, quarry floor <br />elevation, the limestone deposit and overburden. The base of <br />the 50 foot average thickness of limestone (quarry floor) <br />slopes to the southwest as the Portland deposit. The quarry <br />floor will be an extension of the old Concrete Quarry floor <br />which is 60 to 70 feet above the bed of Beaver Creek. This <br />elevation, with the southwest slope of the quarry floor, will <br />enable good control of any sediment problem to Beaver Creek <br />from the quarry operation. The small volume of overburden <br />will be stockpiled westward from the initial quarry cuts and <br />later returned to the depleted quarry floor as the only available <br />soil substitute for reclamation purposes. <br />(3) "Will Ideal agree to provide the Board with channel con- <br />figuration and design for Bear Creek before any diversion <br />is started (in about 25 years)? <br />The statement in my letter dated September 8, 1978 that this <br />diversion would be in accord with regulations and engineering <br />practices applicable at the time the diversion is designed <br />was intended to include Board approval as well as those ap- <br />provals required from all water, environmental and governmental <br />agencies. <br />If you would like any additional clarification of items, please <br />advise. <br />Sincerely, _~~~ <br />' ~~"~ <br />G ~j~, ~ <br />~~C ~ ~~•:'uL~•' ~ ~ <br />K~,~, <br />R.
