RULE 2 - PERMITS
Centerline profiles of the access roads are presented on Map 2.05.3 M3. A schematic showing the
typical cross section is shown as Figure 2.05.342, Typical Access Road Cross - Section.
All access roads will be constructed in accordance with Rule 4.05.2. Typical construction practices
for access roads will involve implementing temporary drainage and sediment control measures,
clearing and grubbing vegetation (limited to the width needed for the roadway and drainage
control), and recovery and stockpiling of available soil materials. All soil material recovered from
roads and other areas will be placed in the topsoil stockpile located adjacent to PECOCO Pond.
Mine access roads will be constructed with a minimum of 36 inches of compacted road base
material, topped with a 12 -inch gravel base, and 6 inches of gravel surfacing or 4 -5 inches of
asphalt. No potentially acid- and/or toxic - forming or frozen materials will be utilized in either road
fill construction or as road surfacing materials.

In -Pit Roads — Road F of the proposed roads is located within or adjacent to the active mining area
and are therefore considered in -pit roads, consistent with the applicable regulatory definition. From
a construction, use, and maintenance perspective, these roads will generally be designed and built to
the same standards as haul roads, consistent with the following road descriptions. The posted speed
limit for all in -pit roads will be 25 mph.
