NOTES
1. The four Phases shown on this map are the operations areas for the
mining and reclamation activities that constitute the development of
this property as a series of water storage reservoirs.
2. Activities within each Phase will include, but is not limited to, mining
of sand and gravel, construction of reservoir liners, grading, recoiling
and revegetation of the above -water perimeter areas of said
reservoirs.
3. The Plant Site shown in the Phase 4 will be used throughout the life
of the mine and activities may include, but are not limited to,
processing the sand and gravel (crushing, washing and screening) ;
crushing and recycling of concrete and asphalt materials; botching of
ready -mixed concrete; botching of hot -mix asphalt; stockpiling of raw
and finished products, and sales of said materials.
4. The Plant Site shall include the necessary portable processing plants
and equipment to conduct the activities listed above. For the sand
and gravel processing, and the concrete and asphalt recycling, the
processing equipment shall include, but is not limited to, crushers,
screens, conveyors, stackers, feeders, log -washers, and other
necessary processing equipment. For ready -mixed concrete, and
hot -mix asphalt, a portable concrete batch plant and a portable
asphalt batch plant may be installed and used for the life of the mine.
5. The conveyor crossing envelopes shown on this map are the approved
proposed crossings in the Town of Platteville POP agreement. The
conveyor design and final locations will be approved prior to
construction of the conveyors.
6. The approximate locations of (2) Conveyor Crossing Envelopes are
hown hereon. The exact location and size of the crossing areas will be
determined prior to installation. A Technical Revision will be filed
showing the exact location if different fro m shown on the Map
Exhibit C-1 Mining Plan Map. These crossings will be used, when
approved by the Town of Platteville, to build overhead portable
conveyor facilities to transport raw material from the north side of
County Road 32.5 to the processing plant. Using over -the -road
conveyors would greatly reduce heavy off -road truck traffic that
would cross the paved road. Conveyor facilities will be removed when
reclamation is complete.

7. The reservoirs will have gravel access roads around the perimeters of
each reservoir and the rest of the perimeter area will be revegetated
with a state -approved seed mix.
8. Access points for each Phase are shown on this map. The accesses to
the Phases will be used to move equipment, needed during mining and
reclamation, from one area to the other. The access point into the Plant
Site from County Road 21 will be used by customers' over -the -road
trucks to transport finished materials to market.
9. Each Phase may continue to be used for agricultural purposes until the
permitted mining operations begin in the area.
10. 'The FEMA Flood Plain (Zone A) shown hereon is approximate and
represents the best information available at the time this document was
created and is subject to change.
11. The four mining Phases shown hereon may change as mining and
reclamation progresses, depending on future Oil and Gas activities at the
site.
12. Working faces show on the map are located at points where they will be
the longest in each Phase. Volume shown is based on average depth of
the Phase.
13. The approximate access points for each Phase are shown hereon. These
accesses will be used to move equipment, and access each Phase during
mining, development and maintenance of each Phase.
14. The unmined areas shown hereon may be used during mining and
reclamation for placement of soil stockpiles, staging areas and as
setbacks. If disturbed, they will be reseeded.
15. The settling and fresh water ponds shown in Phase 1 will be used for
cleaning process water from the plant. Location may change to the
reservoir floor once that area is mined.
16. In Phase 2 along the river, mining will occure within 300 feet of the top
of bank and backfilled with on -site material so there is a 300 foot wide
setback. No more then 500 feet of backf ill area will be open at
any -one-time.
