this approval to remain valid, you must adhere to the conditions listed in the attached certification and any
additional conditions listed below.
1. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be directed across
the bridge and pre-treated through site-appropriate means (grassed swales, pre-formed scour holes,
vegetated buffers, etc.) before entering the stream. Please refer to the most current version of
Stormwater Best Management Practices.
2. Temporary work pads shall not impede more than half the flow of the stream at any given time.
3. The use of rip-rap above the Normal High Water Mark shall be minimized. Any rip-rap placed for
stream stabilization shall be placed in stream channels in such a manner that it does not impede
aquatic life passage.
4. During the construction of the project, no staging of equipment of any kind is permitted in waters of
the U.S., or protected riparian buffers.
5. The dimension, pattern and profile of the stream above and below the crossing shall not be
modified. Disturbed floodplains and streams shall be restored to natural geomorphic conditions.
6. The Permittee shall ensure that the final design drawings adhere to the certification and to the
drawings submitted for approval.
7. Heavy equipment shall be operated from the banks rather than in the stream channel in order to
minimize sedimentation and reduce the introduction of other pollutants into the stream.
8. All mechanized equipment operated near surface waters must be regularly inspected and maintained
to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic
materials.
9. No rock, sand or other materials shall be dredged from the stream channel except where authorized
by this certification.
10. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent
to surface waters is prohibited.
11. The Permittee shall report any violations of this certification to the Division of Water Quality within
24 hours of discovery.
12. Native riparian vegetation must be reestablished within the construction limits of the project by the
end of the growing season following completion of construction.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You
must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition,
