Under the authority of Rule 7.2.2, the Division hereby notifies Grand Island <br /> Resources, LLC that the determination has been made, effective on the date of this notice, that the Cross <br /> Gold Mine is a Designated Mining Operation. <br /> The Division's determination is based on the following: <br /> The Cross Gold Mine discharges groundwater through the Cross Mine and the Idaho Tunnel portals. The <br /> Cross Gold Mine has historically treated groundwater before it is discharged to Coon Track Creek. The <br /> historic treatment has consisted of routing groundwater through a series of lined ponds and the addition <br /> of lime to the Cross Mine discharge. The discharge of treated wastewater is regulated by the Colorado <br /> Department of Public Health and Environment, Water Quality Control Division under CDPS Permit No. <br /> C00032751. <br /> On January 11, 2022, the Division conducted an inspection of the Cross Gold Mine and observed a new <br /> water treatment system. The system was brought online in December of 2021 and consists of filtration <br /> and adsorption water treatment technology. The Cross Gold Mine is required to treat water to prevent <br /> the discharge of heavy metals into Coon Track Creek. Designated Mining Operations are those <br /> operations at which toxic or acid producing materials may be exposed or disturbed as a result of mining <br /> operations. Rule 1.1(1) defines acid and toxic producing materials as natural or reworked earth materials <br /> having acid or toxic chemical and physical characteristics that, under mining or post-mining conditions <br /> of drainage, exposure, or other processes, produce materials which contain detrimental amounts of <br /> chemical constituents such as acids, bases, or metallic compounds. <br /> OF'Cal <br /> Physical: 1313 Sherman Street, Room 215, Denver, CO 80203 1 P: 303.866.3567 1 F: 303.832.8106 <br /> Mailing: DRMS Room 215, 1001 E 62"d Ave, Denver, CO 80216 https://drms.colorado.gov �`� �0 <br /> Jared Polis, Governor I Dan Gibbs, Executive Director Virginia Brannon, Director <br /> T <SgyE p <br /> 1876�` <br />
