r A buffer strip of vegetation at least as wide as the stream shall be left
along stream banks whenever possible.
r For streams less than 15 feet wide, the buffer zone shall extend at
least 15 feet back from the water's edge.
r When using fertilizer to establish areas of new vegetation for soil
stabilization, use mulches to prevent the fertilizer from washing off
the vegetated areas. Apply fertilizer when there is already adequate
soil moisture and little likelihood of immediate heavy rain.
The programmatic EA process included a comprehensive review of base-
wide environmental procedures and produced enhanced standardized con-
struction procedures that minimized or prevented environmental impacts.
It also enabled adding items to their CATEX list, including:
r Construction that does not significantly alter land use, provided the
operation of the project when completed would not have a signifi-
cant environmental impact.
r Acquisition, installation, and operation of utility and communica-
tion systems, data processing, cable and similar electronic equip-
ment that use existing rights of way, easements, distribution systems,
and facilities.
r Grants of easements or the use of existing rights of way: for use by
vehicles; electrical, telephone, and other transmission and communi-
cation lines; transmitter and relay facilities; water, wastewater, storm
water and irrigation pipelines, pumping stations, and facilities; and
for similar public utility and transportation uses.
The Fort Campbell experience demonstrates the multilevel environmental
impact analysis process and the benefits that can be achieved. The resources
consumed by conducting an EA about every month or two for routine
construction and maintenance projects for a decade were avoided. The pro-
cess to make needed improvement to base operations was streamlined and
proven standardized procedures that minimized environmental impacts
were institutionalized and required.

U.S. Coast Guard Dry Cargo Residue Management Tiered EIS
As discussed earlier and summarized in Section 10.2, the U.S. Coast Guard
(USCG) was charged by Congress with developing rules and regulations to
govern the management of dry cargo residue (DCR) spilled during loading
and unloading of Great Lake carriers. Their charge was to develop regu-
lations that achieved a balance of environmental protection and economic
viability of the Great Lakes shipping industry. Because promulgation of the
regulations was a major federal action potentially affecting the environment,
