A Stormwater Management Plan (SWMP) has been developed for the site and is present on site. <br />After the proposed mine plan and stormwater controls are approved by DRMS and CDPHE, the <br />plan may be revised. This plan, which is required by WQCD, addresses both permanent and <br />temporary best management practices as well as stormwater monitoring. <br />Star Mine Operations plans to submit an Air Pollution Emission Notice (APEN) to the Colorado <br />Air Pollution Control Division (APCD) at the same time as the 112d Permit Application is <br />submitted. This notice will include provisions for controlling fugitive dust from surface activities, <br />roadways and stockpiles. <br />A solvent - cleaning station may be installed in one or both of the maintenance shops. These stations <br />generally consist of a cleaning sink mounted on a small drum of solvent. The solvent is pumped <br />into and used in the sink and then recycled back to the drum via a gravity drain. The drums of <br />solvent are periodically replaced by a vendor that recycles the solvent. If these stations are installed, <br />SMO will acquire the necessary permit(s) from the Colorado Hazardous Materials and Waste <br />Management Division (HMWMD). The electrical transformers to be used on site will not contain <br />Polychlorinated Biphenyls (PCBs). <br />4.
