As detailed in Appendix I, the heavy equipment was calculated to emit 1.04 tons of NOx, 0.53 <br />tons of CO, and 0.04 tons of particulate annually. The construction and materials handling will <br />emit 0.87 tons of PM10 and 0.13 tons of PM2.5. The haul road activities will emit 1.91 tons of <br />PMIO and 0.29 tons of PM2.5. <br />7. Surface Drainage Control Structures <br />Because of the minimal existing soil and vegetation in the area of this proposed surface <br />excavation mechanical barriers will be constructed to control drainage. After these structures are <br />created, the only water entering the open mine area will be the result of limited precipitation. A <br />berm will be constructed on the south side of the overburden stockpile to prevent run-on from the <br />rising slope to the south. A berm will be constructed around the south and east perimeter of the <br />ore to direct any potential run-off from the ore pile to a sediment pond constructed in the low <br />lying area of the former Monogram Pit. A ditch and/or slight berm will be constructed on the <br />up-gradient side of the haul road for drainage control as shown on Map C-1. <br />Monogram Mine - November 2008 <br />D-5
