Drilling, Conley Construction, Schmueser, and Buckley Powder. It is the policy <br />of CC &V management to require contractors to maintain separate SPCC plans that meet the <br />requirements of 40 CFR Part 112. Copies of SPCC Plans for each contractor are on file. <br />4.2 Ammonium Nitrate, Emulsion, and ANFO (Blasting Agents) <br />Ammonium nitrate and emulsion are commonly used for blasting. At CC &V there is no bulk storage of <br />"ammonium nitrate fuel oil" (ANFO). Instead, ammonium nitrate and fuel oil area mixed together at <br />blast hole sites in the pit. Buckley Powder manufactures emulsion on site. Ammonium nitrate is <br />stored in two 70 -ton capacity silos located at the Bulk Emulsion Facility (Figure 2). Emulsion <br />(commonly referred to as "prill ") is also stored in two 70 -ton capacity structures, or silos, in the same <br />general area as ammonium nitrate. Buckley Powder is a contractor to CC &V Gold Mining, and <br />therefore has its own Spill Response Plan /SPCC. <br />4.3 Process Reagents Used in Minerals Beneficiation <br />Process (minerals beneficiation) reagents include hydrochloric acid (NCI), sodium hydroxide (NaOH), <br />sodium cyanide (NaCN), hydrogen peroxide (H and antiscalant. <br />4.3.1 Process Reagents at the ADR Plant ( "Adsorption Desorption Recovery Plant ") and VLF <br />( "Valley Leach Fill ") <br />The ADR Plant uses process (minerals beneficiation) reagents to recover precious metals from the <br />ore. The location of the current ADR Plant is identified on Figures 2 and 6. Diluted cyanide leach <br />solution (typically 0.01% to 0.02% or 100 — 200 ppm) is directed to and from the VLF through an <br />HDPE /steel piping system. Pregnant lines are steel and barren lines are steel /HDPE depending on <br />location. <br />4.3.1.1 Bulk Storage of Process Reagents <br />ADR Plant ( "Adsorption Desorption Recovery Plant ") <br />The following table lists the products stored in bulk or solution tanks at the ADR Plant: <br />Table 7.
