As, such, <br />their plan for dust control is a complete mystery at this time. This is compounded by the fact that <br />the application states that there is no planned water use during development, mining, or <br />reclamation. As such, it is difficult to see how the Applicant plans to mitigate the potentially <br />hazardous dust that would be emitted in large quantities by the proposed Gravel Pit" <br />Division of Reclamation Mining and Safety (DRMS) Response: <br />An APEN Permit was applied for through CDPHE (Application No. 10AC1376F). CDPHE indicated <br />that the mining activities are exempted for the APEN Permit requirements because the <br />production rate of the operation will not exceed 70,000 tons per year. However, an Emission <br />Notice is required for the mining activities and a permit is required for the processing operations <br />(crushing, screening, etc.) <br />As required by Rule 6.4.13, the applicant has indicated they will be seeking CDPHE approval of <br />an Emissions Notice for proposed mining activities and an Emission Permit for the processing <br />facilities (crusher, screen, etc.) <br />The Division has determined that the applicant has satisfied the applicable requirements of Rule <br />6.4.13. <br />3.
