Subject: REQUEST FOR ADDITIONAL INFORMATION
Town of Carolina Beach Marina Renovation and Dredging
Dear Mr. Oakley:
On July 16, 2021, the Division of Water Resources - Water Quality Programs received your CAMA
major development permit application dated April 21, 2021, requesting a 401 Individual Water
Quality Certification from the Division for your project. Your request consists of a permit
modification for the renovation Town of Carolina Beach marina basin including replacement and
relocation of all fixed and floating docks, associated sidewalks and installation of a new bulkhead on
the southern and eastern sides of the marina basin. The project also includes approximately 0.81
acres of excavation within the marina basin. The waters of the Carolina Beach Yacht basin are
designated as SB by the Division of Water Resources. The Division of Water Resources (DWR) has
additional questions regarding the proposed development and has determined that additional
information will be necessary to complete the review of your permit application. The application
is on hold until all of the following information has been received by our office.
Additional Information Requested:
1. Avoidance and Minimization:
The project proposes to excavate areas of the marina basin that are located within and
outside of the existing federal channel location. The existing federal channel is authorized
to a final depth of -8 feet NAD83 (-6 feet plus -2 feet of overdredge allowance). The project
proposes to expand the dredge footprint outside of the federal channel and to increase the
depth to -11 feet NAVD88. The DWR has concerns regarding purpose and need for
expanded excavation. It is unclear if connecting depths downstream can support this
depth without creating create hypoxic conditions at the terminus of the basin that could
result in a significant adverse impact to the aquatic resources and a violation of water
quality standards.

2. The method of excavation (hydraulic vs. mechanical) has not been disclosed nor has the
proposed spoil disposal site. The DWR is concerned that pollutants may be present within the
dredge spoil material. Constituents such as heavy metals, inorganic and organic volatile
compounds could be released into surface waters through hydraulic and mechanical excavation
of the soft bottom substrate. The release of these pollutants into the waters could result in a
significant adverse impact to aquatic resources and in a violation of water quality
standards. Please demonstrate how downstream waters will be protected. The DWR
recommends, at a minimum, an initial evaluation of the dredge material as described in the
EPA/USACE Evaluation of Dredged Material Proposed For Disposal at Island, Nearshore or
Upland Confined Disposal Facilities. - Testing Manual be conducted. Depending on the results of
the evaluation, a sediment sampling plan may be required.
Pursuant to Title 15A NCAC 02H .0502(e), the applicant shall furnish all of the above requested
information for the proper consideration of the application. Please respond in writing within 30
calendar days of receipt of this letter by sending one (1) copy of all of the above requested
information to the 401 & Buffer Permitting Branch, 1617 Mail Service Center, Raleigh, NC 27699-
1617 OR by submitting all of the above requested information through this link: https://edocs.deq
.nc.gov/ Forms/ Supplemental -Information -Form (note the DWR# requested on the link is
referenced above).
If all of the requested information is not received within 30 calendar days of receipt of this letter,
the Division will be unable to approve the application and it will be returned. The return of this
project will necessitate reapplication to the Division for approval, including a complete application
package and the appropriate fee.
Please be aware that you have no authorization under the Water Quality Certification Rules for this
activity and any work done within waters of the state may be a violation of North Carolina General
Statutes and Administrative Code.

or concerns.
