EBCI 401 CERTIFICATION GENERAL CONDITIONS.
Measures shall be taken to prevent or control spills of fuels, lubricants or other toxic
materials used in construction from entering the watercourse.
2. All dredged material shall be removed to an upland location and/or graded on adjacent
areas (so long as such areas are not regulated wetlands), to obtain original streamside
elevations, i.e. overbank flooding shall not be artificially obstructed.
3. In areas not riprapped or otherwise stabilized, revegetation of stream banks and
riparian zones shall occur concurrently with project progression. At a minimum,
revegetation will approximate pre -disturbance conditions.
4. To the maximum extent practicable, all instream work under this certification shall be
performed during low flow.
5. Heavy equipment, e.g. bulldozers, backhoes, draglines, etc., if required for this project,
should not be used or operated within the stream channel. In those instances where
such instream work is unavoidable, then it shall be performed in such a manner and
duration as to minimize suspension of sediments and disturbance to substrates and
bank or riparian vegetation.
6. Any fill or riprap including refuse fill, shall be of such composition that it will not
adversely affect the biological, chemical or physical properties of the receiving waters
and/or cause violations of water quality standards. If riprap is utilized, it is to be of
such weight and size that bank stress or slump conditions will not be created because
of its placement.
7. If there are water supply intakes located downstream that may be affected by increased
turbidity and suspended solids, the permittee shall notify the operator when work will
be done.
8. Removal of existing riparian vegetation should be restricted to the minimum necessary
for project construction.
9. Should evidence of stream pollution or jurisdictional wetland impairment and/or
violations of water quality standards occur as a result of this activity (either from a
spill or other forms of water pollution), the EBCI Water Quality Section shall be
notified immediately by calling 828-359-6772.
* EBCI Water Quality Standards are incorporated as Section 113E of the Cherokee Code.
