Corps Action ID# SAW-2001-20723
Dear Mr. Lanier:
On March 13, 2024, the Division of Water Resources (Division) received your application requesting a
401 Individual Water Quality Certification and Neuse Buffer Authorization from the Division for the
subject project. The Division has determined that your application is incomplete and cannot be
processed. The application is on -hold until all of the following information is received:
1. If the US Army Corps of Engineers (USACE)requests a response to any comments received as a
result of the Public Notice, please provide the Division with a copy of your response to the
USACE.
2. You have indicated steep slopes as a reason why onsite Alternative B is not feasible to further
minimize the proposed impacts. However, the airport's publicly available Airport Layout Plan
shows this area to be developed with future hangers and apron, which appears to contradict the
statements provided in the application indicating this area is not suited for hanger development.
3. The application states that onsite Alternative B would not significantly avoid or minimize
impacts to wetlands because approximately 10 acres of wetlands will be impacted by the
proposed Midfield Development Site. However, the current application proposes 18.67 acres of
wetland impact when associated infrastructure and stormwater treatment systems are included
and therefore Alternative B does appear to significantly reduce impacts.
4. The application states that multiple small SCMs were deemed infeasible due to the nature of the
planned site construction. While it is understandable that one SCM may be preferred for
construction simplicity, please provide additional justification for the proposed stormwater

management plan given the significant impacts proposed for the proposed SCM. In addition the
area proposed as the borrow site appears to have been discounted for a SCM location because it
would require stormwater to be pumped to the area, but it is unclear if the analysis is based on
the existing elevations or the proposed elevations after the area is used as a borrow site
It appears that there is further opportunity for minimization of impacts from the SCM if it were
shifted towards the existing runway. The Aquatic Resources Map provided with the application
shows uplands between the proposed location and the runway, and it appears that it would be
feasible to shift the location of the proposed SCM and further minimize wetland and stream
impacts.
6. Notwithstanding the comments above regarding further avoidance and minimization of the
Stormwater Management Plan (SMP), please provide the following information for the
proposed SMP:
a. Please clearly identify the O&M for the submerged gravel wetland (i.e. add SGW in the title).
The provided description in the O&M table for SGW appears to be incomplete, please
review and revise as needed. Also, please provide additional details on the SGW design
summary/table (similar to the dry pond table).
b. Please provide a draft monitoring plan for the SGW as proposed and in accordance with the
protocols outlined in the 2023 NC Stormwater Control Measure Credit Document, Part C.
Please clarify if any additional impacts are necessary for temporary construction access and/or
appropriate sediment and erosion control measures. The Division is particularly concerned with
how the SCM will be installed without impacting adjacent wetlands and/or streams and ensuring
that downstream water quality will be maintained (of particular concern is turbidity and
sediment impacts).
Pursuant to Title 15A NCAC 02H .0502(e) and 15A NCAC 02B .0611, 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.deg.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 denied as incomplete. The denial 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 Section 401 of the Clean Water Act or the
Neuse Buffer 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.
