Table ES-3: Summary of Environmental Impacts
Resource
Category
Alternative
National Environmental Policy Act
(Land and Territorial Waters,
12 nm)
Section 3.1
Geology, Soils,
and Bathymetry
No Action
Alternative,
Alternative 1,
or
Alternative 2
Under No Action Alternative localized
disturbance to topography and localized
erosion would continue; however,
topographic and surface soil changes
would be minimal and would be
managed in accordance with established
protective measures. Dispersion and
suspension of marine sediments as a
result of detonation of underwater mines
and Explosive Ordnance Disposal (EOD)
demolition would continue. Continuation
of disturbance to some sandy beaches;
these effects would be similar to that
from normal wave action during stormy
conditions.
Under Alternative 1 and Alternative 2 the
impacts would be similar to those
described under the No Action
Alternative; however, the intensity of
impacts to geologic resources and soils
would be greater.
Impacts would be similar to those
described for the No Action
Alternative, Alternative 1, and
Alternative 2 for territorial waters.
No significant harm to geology,
soils, and bathymetry resources.
Section 3.2
Hazardous
Materials
No Action
Alternative,
Alternative 1,
or
Alternative 2
Under the No Action Alternative use of
training materials would continue
deposition of expendable training
material on the ranges. Most of the
degradation products of these materials
are nonhazardous inorganic materials.
Under Alternative 1 and Alternative 2 the
impacts would be similar to the No
Action Alternative; however the rate of
deposition of expendable training
material on the ranges would slightly
increase compared to the No Action
Alternative.
Existing ashore hazardous material and
waste management systems are
sufficient for handling of wastes
generated under the No Action
Alternative, Alternative 1, and Alternative
2.
Impacts would be similar to those
described for the No Action
Alternative, Alternative 1, and
Alternative 2 for territorial waters.
Existing hazardous materials and
waste management systems are
sufficient for handling of wastes
generated by the No Action
Alternative, Alternative 1, and
Alternative 2.
No significant harm to resources
from hazardous materials and
waste.
