<br />MINING PLAN
<br />70�nr1�� The primary natural recoverable resource of th': ..ite is sand
<br />� e� and gravel with the possibility of a secondary marketable
<br />G product of topsoil if an excess of such is produced over and
<br />above that required for land reclamation. 'lining of this
<br />material untails creation of a gravel pit. Wash water settl-
<br />ing pond construction, clear water recirculation pond construct -
<br />ion, ditch relocation, and access road improvement and
<br />construction will also occur as a part of this project.
<br />« _ Material extraction will begin on the westerly end of Area 1,
<br />- `-` '�-
<br />(Figure 5) and proceed easterly until an excavation is
<br />produced to accommodate the relocation of the feeder ditch.
