' 6. ENVIRONMENTAL PROTECTION AND SAFETY: (Con't.)
The type o£ environmental pollution most commonly associated with mining
operations of the type proposed for the site is the addition of particu-
late matter (dust) into the air in the area. Fugitive dust has two sources
~ ~ in gravel operations: wind erosion of fine-grained overburden materials,
and rock dust generated by crusher operations. The overburden at the
site is considered the most likely source for fugitive dust. The sequence
o£ operations is such that most of the overburden is handled only once;
from the new mining site to its final location as shaping and topsoil on
the previously mined area.
i ~ As soon as possible the area will be landscaped and planted. The lack of
overburden stockpiles should drastically minimize this source of air
~ pollution.
The gravel materials which will be processed through the crusher at the
' site will be in a moist condition. This will result in a much lower pro-
duction of dust than F the material were dry.
I The mining operation itself will be much lower than the surrounding area
and generally be handled in a moist condition due to de-watering necessary,
which should minimize the dust from this phase of the operation. Generally,
all operations at the site produce noise at a low level.
Safety considerations at the site can be divided into two general categories.
(1.) Operational safety by authorized personell, in which the operator has
the responsibility of providing proper instruction, warnings and equipment;
and (2.) Unauthorized entry by persons--in which the property will be
property posted.
Generally, the sites will be excavated to the finished slopes and grades
during the gravel extraction operation. The banks of the ponds will be
cut at 3:1 (horizontal to vertical ratio ) from 5 feet above to 10 feet
below the expected water line; below the 10 foot level, slopes will not
exceed 2:1.
' 7. SITE ACCESS AND TRAFFIC:
A single access located at the Northeast corner of the site will serve
the site. The entrance will be enlarged to provide good turning movement
