Rule 6.5 Geotechnical Stability Exhibit 1. Patriot Powder LLC's stability and impacts report is provided in Exhibit D. Response to Topics in Timely Objections Received by DRMS • Compliance with local zoning/land use restrictions: DBC submitted a preliminary Location and Extent application to Jefferson County on August 13,2020. DBC intends to comply with applicable county regulations. • Dust and air pollution: The Golden Mine operates under CDPHE APCD Permit No.92JE940F. • Traffic: The mine operation will be consistent with clay mining of the Dakota Mine and Flintlock Mine on the same hogback. It is not anticipated that traffic will change. DBC secured the services of LSC Transportation Consultants who performed a traffic study and submitted an access permit application to CO Department of Transportation (CDOT). CDOT issued an access permit on September 3,2021. • Preservation of fossils: CO State Land Board (CSLB) shared the archeological survey report. DBC is aware of the area and will proceed as directed by CSLB. • Stormwater runoff: DBC operates under the CDPHE WQCD Stormwater Permit No. COG501852. Mining operations will be consistent with decades of mining on the hogback thus stormwater runoff issues are not anticipated. • Mine safety: DBC must operate in compliance with MSHA regulations. • Potential negative impacts to local economy and property values: The Golden Mine has operated since 1940 without negative impacts to the local economy and property values. In fact,the area has prospered both economically and property values. • Potential negative impacts to wildlife: Exhibit H addresses this concern. • Potential negative impacts to groundwater quality: The mining operation will not intercept groundwater. Exhibit G addresses this concern. • Potential negative impacts to wetlands and floodplain areas: The proposed permit boundary does not encompass wetlands and does not include floodplain areas. • Possible damage to nearby structures from mining activity: DBC assumes this is regarding the infrequent blasting performed by a state certified third party blaster. Exhibit D contains a report that addresses this concern. • Possible adverse impacts from the presence of a geologic fault on the site: Historic documents indicate the clay resource in the hogback was been mined since the mid-1800's. The Dakota Mine was mined out and reclaimed by DBC. The Flintlock Mine was mined out and reclaimed by General Shale. DBC has held the CSLB lease since 1940 and has mined in recent years. All of this mining activity has transpired without adverse impacts from the presence of a geologic fault. • Past violations against the operator: DBC is required to resolve agency compliance advisories and violations in a timely manner and will continue to do so. • Issue of completeness and adequacy in the provided application: DBC resolved completeness issues on September 8,2021. This response is submitted to address application adequacies.
