• Potential ARD generated from the waste rock will be controlled with <br />the use of pad-related stormwater BMPs in combination with the <br />newly placed diversion channel and the eventual removal of the waste <br />rock pile itself. <br />Potential stormwater sediment will be minimized with the regular <br />maintenance and upkeep of the access road and pad stormwater <br />management practices <br />d. Good Housekeeping <br />Good housekeeping measures are a necessity for the orderly and safe <br />activities at the mine. A temporary building has been established for <br />worker convenience, changing room, break room, manuals and other site <br />documentation. Tools, storage, lubricants/degreasing solvents etc.. are all <br />appropriately stored at this building. Other materials required for mining <br />are stored out and away from the working area of the pad. Housekeeping <br />is a routine component of the mining schedule. Daily routines require that <br />all refuse be discarded and transported off the mine. GGI personnel will <br />review the housekeeping conditions during their routine site inspections as <br />part of the stormwater management practice review. <br />e. Spill Prevention and Response Procedures <br />Fluid material historically stored or used outside within the Level 6 pad <br />has been removed or will be stored within the on-site building to eliminate <br />potential contact with stormwater. The most likely source of spills would <br />be from machinery of vehicle fuel/oil leaks. Machinery and vehicles are <br />maintained in working order and should not act as a significant source of <br />these types of spills. Solvents and machinery tools are kept within the <br />workshop and storage building. In summary, it is unlikely that any spills <br />would occur as a result of activities within the Level 6 pad. <br />The only fluids managed at the site included fuel and lubricants for tools <br />and machinery. As per regulatory requirements, these types of fluids <br />when spilled can be managed by physical removal with the use of sorbent <br />towels or by excavation. Therefore, in response fluid spills will be <br />responded to in an appropriate manner with the absorption of any free - <br />spilled fluids with the use of sorbent towels. These towels will then be <br />properly disposed of with any residual material being mixed in with <br />surface materials and shoveled into barrels or bags for disposal. <br />Drums used for disposal, and any metal container used for fluid storage <br />will be kept on pallets or other raised surfaces so as to minimize corrosion <br />of their bases, and will also be covered to prevent accumulation of water. <br />The spill storage drums or bags will be disposed of properly by following <br />standard RCRA manifest requirements which may entail material testing <br />for flammable components. Upon completion of testing and coordination <br />with the appropriate landfill, spill materials will be transported off-site to <br />Page 13 of 16
