According to well records obtained from the State Engineers Office, there are a total of 16 <br />recorded wells in section 27, of which 6 are producing wells ranging from 5 gpm to 10 gpm <br />(gallons per minute). Depth to water level for the producing wells ranges from 455 feet to 780 <br />feet. In section 23 there are 12 wells listed ranging in depth from 520 feet to 620 feet. Of the <br />12 listed wells only six are producing, ranging anywhere from 5 gpm to 6 gpm. In Section 24 <br />there are nine recorded wells ranging in depth from 408 feet to 470 feet (well water depth) of <br />which three are producing wells ranging from 4 gpmto 10 gpm. There are no recorded wells <br />in section 22. <br />The depth of mining is going to be from 60 feet to 100 feet depending on the depth of <br />overburden and the aggregate to be mined in the proposed amended area. The probability of <br />any spill from the operation reaching any producing wells without a direct conduit to these <br />wells, such as a pipe or other man made structures directly connected to the wells, is very <br />unlikely. The Division believes the probable impact from fuel spills to existing adjacent wells <br />to be negligible. There is no asphalt batch plant proposed in the amendment application; if <br />there was the SPCS plan would apply. <br />2) The commercial wells needed for the operation can have <br />adverse effect on our wells, even the water supply to the <br />town of Calhan; millions of gallons of water can affect the <br />Hydraulics. <br />As stated in the application, the operator is planning to either utilize the existing well that they <br />have been using to wash the sand or apply for a new well permit from the Colorado State <br />Engineers Office. There is no mention of the amount of gallons to be pumped for the <br />operation as stated by the objector or objectors. A well permit, be it commercial or otherwise, <br />is issued by the State Engineers Office under the Substitute Water Supply Plan and it <br />requires the operator to show that they indeed have the water rights to deplete water from the <br />ground. The operation plans to affect a total of 50 acres at any given time. The existing <br />operation was allowed under the same plan of operation to affect 39 acres. The net increase <br />in affected acreage is 11. If the State engineer issues new well permits, the operator can <br />only pump what is allowed under that permit. The Division did not receive comments from the <br />City Of Calhan regarding impacts to their well from the proposed operation. The recharge <br />area for the aquifer will remain the same; there is nothing that will be introduced by the <br />operator to affect the recharge area other than removing overburden and aggregate material. <br />The Division considers potential impacts to ground water from the operation such as well <br />draw downs to be negligible. <br />3) Demise of wildlife in habitat. <br />Under Rule 6.4.8 (2) the application is reviewed and commented on by the State of Colorado <br />Division of Wildlife (DOW). The Division received no adverse comment or comments from <br />DOW. When the site was expanded from 9.9-acres of operation to the current 112 operations <br />of 41.37 acres, no adverse comment was received from DOW. There are no endangered or <br />threatened species in the area. As required by the Rule the operator has listed all the <br />required information under the Rule and is in compliance. <br />
