<br />Wells drilled in Colorado are registered with the Colorado Division of Water Resources (DWR), and are a
<br />matter of public record. DWR records list 188 unique wells within two miles of the project boundary,
<br />thirteen of which are owned by the Operator (Section 8(a)(iii)). The nearest non-Operator well is located
<br />0.70 miles (3,700 ft) from the mine portal, and 84% are located more than one mile from the mine portal
<br />(Table 8-2).
