Notes:
ma I . This representation of the new stream haul road and LOD area as approved h p is a general p pp owed by the Army Corp. Refer
to the construction drawings provided by DRG for a more detialed plan of this area.
2. Refer to the construction drawings for the erosion control between the new stream and new haul road as provided by
DRG for further detail. Refer to pages EC-1 ,2,3, and 4.
498,8 �\ 3. Adequate measures (e.g. silt fence, straw wattles, etc.) will be maintained between all land disturbance activities and live
streams at all times.
4. Waste area is temporary and will be used for storing of fill material prior to filling back in old stream bed. This area was
previously approved in 2018 to be disturbed.
j
2"7
5. Sedimant Basins with Rock Dams have been moved i h outside the LOD for erosion control prior to construction of new
stream area. These were permitted in 2018 and have been installed. Basins H2O,P, and Q have been moved and will
�' need to be reconstructed as specified in the 2018 engineering drawings.
-- `Y 6. For final buffers off the stream refer to CEC drawing EC-200 "Conservation Easement Layout"

Notes:
1. The plant and stockpile areas will be graded, disced, and seeded according to the approved seeding plan
�~ 2. Once extraction of materials has been completed the pit entrance will be blocked and a boulder wall will be constructed
round the perimeter of the pit for permanent high wall protection.
3. All roads will be graded and seeded according to approved seeding plan. An entrance road will be maintained for site access
4. The plant will be removed and all associated buildings.
5. All structures will be removed from site except the office building.
6. The main pit will fill up with water. The pits as shown to the NW & NE will not extend below the water table.
o 7. If the pits shown to the NW and NE are not mined they will be reclaimed as timber and grasslands but are currentlyshown
~ as pits.
