<br />Water Division 2, Water District 14
<br />Dear Air. McLean:
<br />This letter is in response to your application of June :, 1999, far a substitute water supply
<br />plan for a gravel pit to be operated by Tony J. 8eltramo and Sons, Inc. ("8eltramo") in accordance
<br />with 37-80.120 C.R.S. The required tee of $1,343 for the substitute supply plan has been paid.
<br />According to information submitted, no ground water was exposed prior to January 1,
<br />1981. Il is anticipated toot the wet miring operation at this site will expose a water surface area
<br />no larger t~nan one acre. It is anticipated that the pit wi~l be back-filled upon completion of mining
<br />operations so that, when the reclamation process is completed, there will be no post-mining
<br />depletions. A permanent augmentation plan is, therefore, not required. Applicant has secured a
<br />bond (DMG Bond No. 5998645) in tree amount of $75,000 to provide for reclamation of the site
<br />and back-filliny of the pit in the event the requirements of the reclamation permit are not
<br />completed.
<br />According to information submitted, the antiupated annual depletion to the Arkansas River
<br />due to operation of the f3elli onto Miue Pit will be ;ippruximateiy 1 1.76 acre-feet per year, includlrtg
<br />3.34 acre-feet of net evaporation Irom the exposed groundwater surface, 3.24 acre-feet of water
<br />loss in product, 3.68 acre-teat of water consumed in concrete batch operations and 1.50 acre-feet
<br />of water used for dust control. The 8eltramo Mine Pit will he approximately 2,200 feet of the
<br />Arkansas River, and you have provided a monthly schedule of lagged depletions to the aver,
<br />together with a schedule of replacement requirements totaling t 2.00 acre-feet por year
<br />(attachment Table 3 Revised]
<br />The proposed source of replacement water for this substitute water supply plan is reusable
<br />water purchased from the Board of Water Works by Gf the Arkansas Groundwater Users
<br />Association (AGUA). It is assumed that no transit losses will be charged, because the point of
<br />replacement will be at or belorv the point of depletion io the Arkansas River, but this assumption is
<br />subject to review by the Division 2 Engineer. A memorandum frorrl AGUA to the Colorado State
<br />and Division 2 Engineers dated June 1, 1999 Commits AGUA to provide 18.05 acre feet of
<br />replacement water for two gravel pit substiluto water supply plans during the (AGUA) "plan year
<br />1999 ;0 2000." According to information submitted, AGU.4's Arkansas River Replacemlent Plan
