Other Agency Environmental Protection Measures <br />Local Agencies <br />Before operations resume, the operator will obtain all necessary Local Agency Permits, including, but <br />not limited to: <br />• Special Use Permit from San Miguel County <br />• Road Use Permits, as applicable, to address traffic volume, noise, weeds, storm water <br />management, etc. <br />• Sewage disposal system permit, if a septic system is chosen over a self- contained porta- <br />bathroom system <br />Federal Agencies <br />The project is located entirely on public land managed by the U.S. Bureau of Land Management (BLM). A <br />Plan of Operations will be submitted to the BLM prior to resumption of surface - disturbing work. The <br />identification of appropriate environmental protection (i.e., mitigation) measures will be addressed <br />using the National Environmental Policy Act (NEPA) analysis as a guide. A summary of anticipated <br />environmental protection measures that will be needed if the mine expands follow: <br />• Cultural resources identified as being eligible for the National Register of Historic Places will be <br />avoided. <br />• Socioeconomic impacts to local communities will be positive but relatively minor in extent due <br />to the limited number of employees at the mine, five -to -ten people. <br />• A biological survey of the mine area will be conducted to determine the presence, if any, of <br />threatened or endangered plant or animal species. <br />Other State Agencies <br />Features for a Stormwater Management Plan (SWMP) are described in Section 10 of this plan and shown <br />on the map, Figure 2. It will be in place and implemented before mining activities resume on site. This <br />plan, which is required by Colorado Water Quality Control Division, will address both permanent and <br />temporary best management practices as well as stormwater monitoring. <br />The operator will submit to the Colorado Air Pollution Control Division (APCD) for necessary Air Pollution <br />Emission Notices (APENs). These APENs will quantify potential air pollutants from fugitive dust, <br />generator emissions, and mine ventilation emissions. The mine is small enough that the sources are <br />considered to be minor sources by the APCD. Fugitive dust controls include applying magnesium <br />3 <br />
