Permit Conditions

Conditions
NATIONWIDE PERMIT No. 3
Maintenance
(a) The repair, rehabilitation, or replacement of any previously authorized,
currently serviceable structure or fill, or of any currently serviceable structure or fill
authorized by 33 CFR 330.3, provided that the structure or fill is not to be put to uses
differing from those uses specified or contemplated for it in the original permit or the
most recently authorized modification. Minor deviations in the structure's configuration
or filled area, including those due to changes in materials, construction techniques,
requirements of other regulatory agencies, or current construction codes or safety
standards that are necessary to make the repair, rehabilitation, or replacement are
authorized. This NWP also authorizes the removal of previously authorized structures or
fills. Any stream channel modification is limited to the minimum necessary for the repair,
rehabilitation, or replacement of the structure or fill; such modifications, including the
removal of material from the stream channel, must be immediately adjacent to the
project. This NWP also authorizes the removal of accumulated sediment and debris
within, and in the immediate vicinity of, the structure or fill. This NWP also authorizes the
repair, rehabilitation, or replacement of those structures or fills destroyed or damaged by
storms, floods, fire or other discrete events, provided the repair, rehabilitation, or
replacement is commenced, or is under contract to commence, within two years of the
date of their destruction or damage. In cases of catastrophic events, such as hurricanes
or tornadoes, this two-year limit may be waived by the district engineer, provided the
permittee can demonstrate funding, contract, or other similar delays.
(b) This NWP also authorizes the removal of accumulated sediments and debris
outside the immediate vicinity of existing structures (e.g., bridges, culverted road
crossings, water intake structures, etc.). The removal of sediment is limited to the
minimum necessary to restore the waterway in the vicinity of the structure to the
approximate dimensions that existed when the structure was built, but cannot extend
farther than 200 feet in any direction from the structure. This 200 foot limit does not
apply to maintenance dredging to remove accumulated sediments blocking or restricting
outfall and intake structures or to maintenance dredging to remove accumulated
sediments from canals associated with outfall and intake structures. All dredged or
excavated materials must be deposited and retained in an area that has no waters of
the United States unless otherwise specifically approved by the district engineer under
separate authorization.
(c) This NWP also authorizes temporary structures, fills, and work, including the
use of temporary mats, necessary to conduct the maintenance activity. Appropriate
measures must be taken to maintain normal downstream flows and minimize flooding to
the maximum extent practicable, when temporary structures, work, and discharges of
dredged or fill material, including cofferdams, are necessary for construction activities,
access fills, or dewatering of construction sites. Temporary fills must consist of
materials, and be placed in a manner, that will not be eroded by expected high flows.
After conducting the maintenance activity, temporary fills must be removed in their

entirety and the affected areas returned to pre-construction elevations. The areas
affected by temporary fills must be revegetated, as appropriate.
(d) This NWP does not authorize maintenance dredging for the primary purpose
of navigation. This NWP does not authorize beach restoration. This NWP does not
authorize new stream channelization or stream relocation projects.
Notification: For activities authorized by paragraph (b) of this NWP, the permittee
must submit a pre-construction notification to the district engineer prior to commencing
the activity (see general condition 32). The pre-construction notification must include
information regarding the original design capacities and configurations of the outfalls,
intakes, small impoundments, and canals. (Authorities: Section 10 of the Rivers and
Harbors Act of 1899 and Section 404 of the Clean Water Act (Sections 10 and 404))
Note: This NWP authorizes the repair, rehabilitation, or replacement of any
previously authorized structure or fill that does not qualify for the Clean Water Act
Section 404(f) exemption for maintenance.
