MVBs are operated by connecting a mobile, methane-fueled exhauster to the wellhead. Starting in 2020,
mobile flaring units will be connected to the mobile exhausters to flare MVB emissions from active
and/or sealed longwall panels. These units are typically moved with heavy-duty pickup trucks.

Some methane gas from the sealed mine sections is used to heat mine ventilation air at the Ventilation Shafts
No. 1 & 2, in a system completed in 2003 and amended a few years later. A 10” diameter methane supply
hole was drilled to the B seam to the south of Shaft 3. About 100’ of buried 12” HDPE pipeline ties the
borehole into the existing mine air heater line.

Fire Breaks

Fire Breaks are constructed West the Main Mine Site. The neighboring mine, Bear Mine, has historically had
issues with underground fire that, more recently, has spread to surface fire. In order to protect the Main Mine
Site location and land from fire danger MCC installed a fire break that consists of approximately 1.8 miles of
road that is roughly 20-30 feet wide. The land disturbance for the Fire Breaks is not a mine facility and will
not be used in the future for any activity associated with mining or reclamation. See Exhibit 83 for Fire Break
location. Additionally, MCC will coordinate with adjacent landowner, Lazy H Ranch, to strategically remove
oak brush from 132.6 acres that will provide fire protection to both properties as well as create desired habitat
for wildlife.

Access Road to Bear Mine Site

An access road to the inactive Bear Mine site is located East of MB-5E ponds and extends to the vent holes
that have created a fire hazard to the immediate and surrounding areas. MCC is not liable to reclaim this road
and the disturbance is not a mine facility and will not be used for any mining activity. See Exhibit 83 for
construction, location and use details.

Deer Creek Shaft Facilities

In 2009 MCC constructed Deer Creek shaft. Location and layout design of the Deer Creek Shaft can be found
on Map 53D. The shaft is used as a secondary escapeway from the mine as well as assisting in mine
ventilation. See Exhibit 77 for further details.

Monument Dam Survey Station

The Monument Dam Survey Station is located on the hillside Northwest of the Dam on property owned by
MCC. The station houses continuous survey equipment. The equipment is owned and operated by MCC. A
9-ft security fence surrounds the pad where the station is located.

Box Canyon Water Storage Pumphouse, Waterline and Booster Pumphouse.

The Well House is located just south of the intersection of the Sylvester Gulch Road and the main mine
access road. It sits on a 25’ x 15’ concrete pad, is constructed of a metal frame and tin walls and houses the
drillhole, pump, control room and monitoring hole to pump water from the Box Canyon North water storage
