<br />Dear Mr. Berg:
<br />
<br />We have received your July 25, 2017 letter requesting a revision to the previously approved renewal of
<br />a substitute water supply plan (“SWSP”) in accordance with § 37
<br />gravel pit to be operated by the applicant, Trans Colorado Concrete (a division of Pete Lien & Sons,
<br />Inc.). The mine is permitted with the Division of Reclamation, Mining, and Safety under File No. M
<br />2004-013. The most recent SWSP
<br />December 31, 2018. As stated in your July 25, 2017 letter, the pond surface areas have been updated
<br />through aerial photography and the mining plan has changed; therefore, this request is b
<br />revise the previously approved SWSP dated April 25, 2017. Accordingly, this SWSP supersedes the
<br />previously approved SWSP dated April 25, 2017. The $257 fee has been accepted with receipt no.

<br />PLAN OPERATION
<br />
<br />The St. Barbara Sand and Gravel Mine is located in Section 1, Township 21 South, Range 63 West of the
<br />6th P.M. and Section 6, Township 21 South, Range 62 West of the 6
<br />the St. Barbara Sand and Gravel Mine is projected to continue for approxi
<br />at this time it is uncertain whether mining at the site will occur over the approval period, currently
<br />there is no activity. Therefore, two scenarios were considered; Scenario A assumes that mining will
<br />occur over the approval period and Scenario B assumes that mining will not occur over the approval
<br />period. The maximum exposed water surface area in the five ponds located on the property is currently
<br />at 5.77 acres (0.81 acres-pond 1, 1.56 acres
<br />acres-pond 5). This is the total exposed surface area during all months when mining is not in progress.
<br />
<br />Under Scenario A, Pond 5 will be actively mined from March through November and will be dewatered
<br />via a dewatering trench. The dewatering trench is 3,800 feet in length with an average width of 5 feet
<br />for a total exposed water surface area of 0.44 acres. According to the request, portion(s) of the
<br />pond(s) will be backfilled during mining such that the maximum exposed water surface
<br />all five ponds and the dewatering trench will not exceed 4.57 acres. Operational losses will occur due
<br />to water retained in the mined product and water used for dust suppression.
