ATTACHMENT D <br /> SUPPLEMENTAL INFORMATION <br /> III (K) <br /> Baffled tanks are also utilized in the management of drill cuttings. Drill cuttings settle out <br /> behind the baffles in the fluid recycle process. Cuttings are removed and containerized until <br /> placed back in the drill hole as part of the plugging process. Any excess cuttings will be hauled <br /> off-site and placed in a licensed disposal facility. <br /> Boxes will be used to store and transport core generated in the drilling process. Core boxes are <br /> water impervious cardboard containers designed specifically for core storage. Each box can <br /> accommodate five,two-foot sections (10 feet) of core. Core retrieved from the holes is placed <br /> immediately in core boxes and transported off-site for logging,photo documentation, and <br /> analysis. Each day's production of core is removed from the site by the project geologist. <br /> Traditional aquifers typically require porous rock to host groundwater. Sedimentary rocks, like <br /> sandstones and limestones that are common in the Southwestern United States, are common <br /> hosts to groundwater. The rocks to be intersected by the proposed drilling in the La Plata <br /> Mountains are not sedimentary but are intrusive rocks (diorites and syenites)that are typically <br /> dense or"tight", with interlocking mineral grains that have no porosity. In areas, like around the <br /> Allard Tunnel, where intrusive rocks are the dominant rock type, groundwater is typically <br /> fracture-controlled. Open fractures that could potentially contain water on the property are <br /> typically narrow and widely spaced and under existing drought conditions are not currently being <br /> fed by active runoff. However, if an unanticipated small fracture hosting water is encountered it <br /> can easily be contained through cementing of the interval (as described in the NOI) and by <br /> approved and mandated hole plugging methods when the hole is completed. <br /> Make-up water for the drilling process will be transported to the project using a water-buffalo, or <br /> truck-mounted tank. Approximately 500 gallons of make-up water will be transported each day <br /> to the site by the drill crew for augmentation of the recycle process. Make-up water will be <br /> obtained from a properly licensed water purveyor. <br /> IV Operation and Reclamation Measures <br /> Prior to mobilization of equipment to the site, all equipment will be power washed and inspected <br /> for plants or packed soil that might host noxious weed, or seeds. The waste rock dump will be <br /> inspected bi-annually for a period of two years to make sure that no noxious weeds have <br /> occurred as a result of drilling activities. <br /> Reclamation (Land Accessed). <br /> Reclamation of the drilling locations will occur immediately upon completion of drilling, and <br /> will consist of hole closure, infiltration basin back-fill, wattle removal, site dressing and <br /> equipment removal. <br /> Page 1 of 3 <br />
