SPECIAL CONDITIONS
Carolina Beach Inlet SDI -5
IDMMS Modification
SAW -2014-02006
As part of the operation and maintenance of the federally authorized project, the Wilmington
District routinely surveys and dredges portions of the Carolina Beach Inlet complex the
including, but not limited to, areas *mat its intersection with th
AIWW in order to assess and maintain dredging reeds to mak * iii navigability of the Carotin
Beach Inlet. The permittee must coordinate with the Navigation and Coastal Engineering
branches of the U.S. Army Corps of Engineers, Wilmington District both pre- and post -
construction when use of the IDMMS is proposed.

Beach Inlet, Tthe permittee shall coordinate with SAW's Navigation and Surveying branches t
provide pre-dredging/placement hydrographic (bathymetry) surveys Before Dredge, or BD) o f
the entire inlet complex (to include the borrow area, federal navigation channel and I_inl t
crossing) at least two weeks prior to the commencement of maintenance dredging.
to -This period will allow NHC and the District time to review the survey of the area that may b
potentially affected affected by the proposed maintenance project. The permittee shallcoordinat
with the District o' * r the approval of the n'^*"'^* prior to initiating work on any propose
project that involves disposal of material in the IDMMS. If the District Engineer, in his sole

discretion and with prior NHC coordination„ determines that existing conditions indicate that the
modified activity (disposal of material in the IDMMS) will likely adversely impaet-affect the
Federal Project, to include the borrow area and federal navigation channel, or in the adjacent
AIWW, he will notify the permittee of any limitations on disposal location that will minimize the
potential for adverse impacts effects., or deny the request until more favorable cond tions exist.
The permittee shall coordinate with SAW's Navigation and Surveying Branches to must also
provide post-dredging/placement (After Dredge, or AD) hydrographic (bathymetry) surveys of
the entire inlet complex to the same extent as the pre -dredging survey listed above within 30 days
of the end of construction.
-In the event NHC contracts maintenance dredging of Carolina Beach Inlet and/or the AIWW
crossing through the private sector, all coordination and the BD and AD stipulations will be
followed durine the IDMMS use.

If the District Engineer, in his sole discretion and with prior NHC coordination, determines that
the modified activity (disposal of material in the IDMMS) has caused additional shoaling (above
historical amounts, taking into account inlet dynamics and storm effects) within the Federal
Project's borrow area and potentially effecting the federal navigation channel or the adjacent
AIWW and that such sections should be dredged in order to maintain safe and efficient
navieation_ he will so notifv the permittee in writine. Proiec* to include the borrow area and
permittee in wr g. Additional shoaling above historical amounts is defined herein as the result
of active placement with the IDMMS bottom elevations being sustained above -14' MLW for a
period of one month. The notification will specify the extent to which additional shoaling has
occurred, , the inlet feature that must be dredgedthe area of the inlet Crossing that must be
dredged, the depth to which it must be dredged, and the time frame within which dredging must
begin (a minimum of 90 days will be allowed). The permittee shall either provide contributed
funds to compensate the government for the portion of the costs associated with dredging the
additional shoal material, or cause the area of the Inlet Crossing specified by the District Engineer
to be dredged in a manner and within the time frame specified in the notice.
3— If a USACE's shallow draft dredge operationTesults in -such -short dumps and/or stacking of_ <
material as to potentially effect navigation, the USACE will be responsible for remediating the
area with no recourse to NHC. Likewise, if a NHC contractor's action results in such short _
dumps and/or stackjg of material as to potentially effect navigation, NRC's plans and -------
specifications
_specifications will provide the contractor clear guidance and oversight for site remediation. `

The District Engineer, in his sole discretion and in prior coordination with NHC, may requir
additional remedial action or revoke the modification in the event that surveyed data reveals
contours not consistent with federally authorized depths. A 90 -day window will be allowed for
any remedial action required to restore the area to federally authorized and maintained depths.
