An existing trail (approximately 1500 feet in length) will be improved and left as a road for access to the upper area. An existing portion of this road (0.4 acres) is located in the west buffer zone. The north part of the site will be accessed via a road of approximately 1000 feet in length, again permanent, connecting to the first at the top of the cliff (just inside the buffer zone). ACCESS: For mining purposes, access to the pit shall be limited to the road and private bridge over the San Juan River on the west perimeter of the permit area, connecting County Road 500 (Trujillo Road South). This road will be graveled according to Archuleta and user requirements, and may be treated with mag -water or other dust control agents, as part of regular maintenance. This access will also be used for agricultural purposes. PIT ROADS (HAUL): Various other pit roads will be constructed and used in the permit area for various periods of time. The exact routing of those roads will be identified as mining proceeds, and are not shown on maps. These roads will normally be on a mined surface, but may be on the original ground surface (after stripping). All roads providing access to temporary plant sites will be all- weather, gravel, minimum 24 -feet width or as required by MSHA standards for mine haulage, mine access, fire and other emergency purposes; other roads may be narrower but will meet MSHA standards. Roads will include drainage features (ditches, culverts, berms, check dams, etc.) as required by proper design and maintenance requirements, storm water and related permits, safety berms or other devices as required by MSHA, and signage as required by MSHA and OSHA standards for mining and industrial /commercial purposes. The existing road /trail and new, temporary trails will be used as necessary to provide ranching access to areas of the property not being mined, as well as access where needed on a seasonal, short -term basis for preparation, emergency access, reclamation, and inspection, and are not be shown. Existing bridge and roads (but not trails) are considered significant permanent structures. C &J Gravel Products, Inc.
