STORMWATER MANAGEMENT PLAN <br /> NEWMONT <br /> CRIPPLE CREEK AND •' GOLD MINING COMPANY <br /> 4.2.8 Disturbed Areas <br /> Haul roads are surfaced with gravel and constructed with drainage ditches that lead to road sump BMPs <br /> that detain stormwater to settle sediments, or to filters such as erosion logs, silt fences, vegetative filters, <br /> and engineered stormwater management ponds(EMPs). Administrative areas, such as the security offices, <br /> parking lots, access roads, and delivery docks, are monitored for potential "track-out' of mud and other <br /> sediment onto public roads nearby. <br /> 4.3 Best Management Practices <br /> 4.3.1 Stormwater Diversion <br /> Stormwater runoff will be diverted to the extent practicable around disturbed areas and areas where <br /> chemicals, fuel, or other potential contaminating materials are handled or stored. <br /> The following are the most significant handling and storage areas at CC&V and the corresponding BMPs, <br /> methods and controls are used to divert stormwater away from each area. <br /> • The VLFs are both zero discharge facilities that are bermed along the perimeter to contain the <br /> process solution and to prevent run-on. Stormwater that could potentially enter the VLF from up- <br /> gradient areas is diverted around the VLF. Stormwater falling on the VLFs is retained in the <br /> processing circuit. Each VLF is designed and operated to maintain the process solution inside the <br /> lined containment areas during precipitation events and under extreme conditions. <br /> o With completion in 2004 of Arequa Gulch VLF Phase IV construction, surface water <br /> contributions to Arequa Gulch were reduced and some of the flows have been directed to <br /> Bateman Creek through EMP-006. Likewise, with completion of Phase V of the Arequa <br /> Gulch VLF, the watershed was further reduced in size and stormwater flows were reduced <br /> accordingly Stormwater flows that were previously generated from the Squaw Gulch <br /> Overburden Storage Area (SGOSA) are now contained within the Squaw Gulch VLF <br /> Process Circuit. <br /> • The ADR Facilities and adjacent chemical storage areas are on lined foundations that ultimately <br /> are directed to the VLFs. Stormwater that could potentially enter from up-gradient areas is diverted <br /> around these lined facilities; stormwater falling on the area is retained and directed to the VLF <br /> process circuits. <br /> • The Midway Fuel Farm stores gasoline, diesel, kerosene, lubricants, antifreeze, washer fluid, and <br /> diesel additives. The Midway Fuel Storage Area is a lined facility with a down-gradient control <br />
