Dear Ms. Mayhew:

Nash County
On March 1, 2016, the Division of Water Resources (Division) received your response to our
request for additional information dated February 24, 2016 regarding your request for an
Individual Water Quality Certification / 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. Title 15A NCAC 02H .0506 requires that a proposed activity has no practical alternative by
demonstrating that, considering the potential for a reduction in size, configuration or
density of the proposed activity and all alternative designs, the basic project purpose
cannot be practically accomplished in a manner which would avoid or result in less
adverse impact to wetlands. Because the preferred alternative involves the greatest
amount of wetland impact, the Division cannot review this alternative until the U.S. Army
Corps of Engineers (USACE) determines that this alternative is the least environmentally
damaging practical alternative (LEDPA). Please provide correspondence from the USACE
indicating which alternative is selected as the LEDPA.
2. Stream impact S3 — 5.48 linear feet is labeled as a temporary impact. This should be
classified as a permanent stream impact since the stream will be relocated away from
this small section of channel and it will no longer receive upstream flow.
3. Stream impact S1— 462.20 linear feet is labeled as temporary. Since the channel will be
filled, this should be classified as a permanent impact. Relocation of the stream will be
considered as self -mitigating.

4. Grading and revegetation (fill) in Zone 2 of the buffer is an exempt activity that does not
need to be quantified. The stormwater discharge into the buffer from the stormwater
BMP is an allowable activity that requires the impact to be quantified for
approval. Please remove B2 entirely and revise B3 to limit the impact to the stormwater
discharge only.
5. Explain how erosion in Zone 1 from the SW discharge will be prevented. These types of
discharges are usually connected to the stream channel unless the discharge is
anticipated to be non-erosive.
6. Add a dashed outline of the existing road within the buffer to make the existing use
clearly discernable on the buffer impact map.
This Office has the following comments regarding the stream restoration design. Please
feel free to contact Mac Haupt at 919-807-6476 or [e-mail] if you have
any questions regarding the stream restoration design recommendations.
a. Green ash should be substituted for loblolly pine in the planting plan.
b. Proposed log sills should be installed with footers and/or matting to prevent
piping and eventual undermining.
Pursuant to Title 15A NCAC 02H .0502(e) / 15A NCAC 02B .0233, the applicant shall furnish all of
the above requested information for the proper consideration of the application. If all of the
requested information is not received in writing 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 respond in writing within 30 calendar days of receipt of this letter by sending three copies
of all of the above requested information to the 401 & Buffer Permitting Branch, 1617 Mail
Service Center, Raleigh, NC 27699-1617.
Please be aware that you have no authorization under the Section 401 of the Clean Water
Act/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.
