Dear Tim,
I would like to request an additional extension for the Sweetwater Project. The gas company is working with the
landowner to get their buy in, the most recent design (which I previously provided) is till additionally being reviewed by
the Gas Co for constructability. Can we extend to February 13, 2015? I'm hopeful that the parties can come to a mutual
agreement by this date.
Thanks!

Crystal, -
I did not see any glaring conceptual design issues. However, DWR will want to assess the stability of the project. We
will want to see the outlet protection detail, pipe slope information, invert elevations, pipe profile and any other
appropriate information. The project will need to meet the general conditions for Water Quality Certification 3883.
Please follow and submit your response to the address on the Additional Information Requested letter

Good Morning Crystal;
The attached PDF shows all the storm features from the survey. That really is just the existing 24" pipe, and the 18" pipe
with an inlet at Sweetwater Hills road. I was told that the 24" pipe also connects to a road inlet, but oursurvey didn't
extend far enough to show that.
The PDF shows the existing pipes as black lines; and the proposed pipes are dashed wide green lines. The proposed
manholes are yellow circles, and have 5' separation from the gas line.
If it is possible, can you get an existing depth ofthe existing gas line? We need to have an accurate size and depth of
that line to see if we can get the proposed outfall pipe underneath the gas line.
Please let me know if I can be of any further assistance
Thanks,

Dear Mr. Fox and Ms. Higgins:
On behalf of our client, PSNC Energy, S &ME, Inc. (S &ME) is hereby providing
additional information pursuant to written approval of a Section 401 Water Quality
Certification (WQC) No. 3883 application, previously submitted on September 8, 2014.
A letter from the North Carolina Division of Water Resources Asheville Regional office,
dated October 14, 2014, requested additional information regarding property owner
approval and a stream restoration design based on natural channel design principles,
outlined in more detail herein.
Since that time, a conference call with Mr. Kevin Barnett and Mr. Andrew Moore (DWR)
and S &ME was held to clarify conditions on site and receive more input regarding
potential 401 requirements. Mr. Barnett and Mr. Moore followed up the conference call
with an October 19, 2014 email where additional considerations and potential
construction design options were presented (attached). On November 12, 2014, S &ME
conducted a site visit with DWR (Mr. Tim Fox and Mr. Zan (George) Price) to clarify the
project plans and address changes since the first submittal. Since the original submittal,
property owner negotiations have limited the current proposed impact area to the existing
right -of -way, reducing workspace, and thereby reducing impacts to Waters of the U.S.
Present at this site visit with DWR were the property owners, representatives of PSNC,
and Ms. Crystal Fox and Mr. Mark Taylor of S &ME. All present provided input with
regard to their respective interests. As a result of these on -site discussions and further
S&ME, INC. / 9751 Southern Plne Boulevard / Charlotte, NC 20273 -5560 /p 704.523.4726 1704.525.3953 /e vmsmeincxom

Response to Request for Additional information SSME Project No. 1356 -14 -664
Sweetwater Hills Drive Stream Stablj!Zqilon. H Hendersonville, el a 2015
- commentary with the property owner, PSNC proposes to install a culvert and armored
outfall which will allow PSNC permanent access, maintain the aesthetics in the property
owner's front lawn, prevent further degradation of the channel, and protect the existing
gas line from exposure and damage (See attached, Drawings and Specifications 1 -6).
S &ME's response to the original October 14, 2014 letter is provided below. Please note,
since the original submittal, proposed impacts have been reduced while incorporating
property owner concerns, PSNC concerns, and DWR concerns.
1) The project proposes to restore a reach of stream located on a property
owned by others not included in the application documentation. Proof will
be needed that the property owners approve work to be completed on their
property, as they will be responsible for the outcome of the project and
compliance with 401 Water Quality Certification conditions.
Since the previous submittal, project constraints have changed such that all work will be
conducted within an existing gas line easement (see the attached Easement Agreement).
Further, the property owner's were present during the field meeting and are in agreement
with proposed activities (see attached email correspondence).
2) The project proposes the use of gabion baskets, which are not considered an
approvable method to utilize for stream restoration and the design creates an
obstacle to aquatic passage, also not approvable. Provide stream restoration
details based upon natural channel design principles.
The original submittal included 91 linear feet (If) of stream bed impacted by stabilization
measures. Since work downstream of the gas line right -of -way is no longer proposed,
there is no stream restoration component. The current design limits permanent impacts to
approximately 43 If of stream, reducing the impact length by approximately 47% of the
previously proposed erosion stabilization design. Further, PSNC proposes to install a
culvert and associated structures which will convey the flow of the stream in a more
graduated manner than previously proposed. Two precast concrete manholes will be
installed which will connect to the outlets of the existing 24 -inch and 18 -inch diameter
culverts. The manholes will serve as a debris cleanout access enabling maintenance
access to the culvert for clean out, etc. The existing 24 -inch corrugated metal pipe will
be cut to allow for a tie in to the proposed 33 -inch diameter re- enforced concrete culvert
extension will be installed and covered with approximately 6.5 feet of clean fill material
to provide permanent access to the existing maintained right -of -way. The culvert will be
installed such that the bottom of the culvert conveys water in a gradual manner
downstream. The fill bank above the culvert extension will be re- graded and protected
using rip -rap above the proposed headwall. Boulder -sized energy dissipaters will be
placed at the outlet of the culvert extension to prevent undermining of the culvert and
reduce the velocity of flow before continuing downstream. To the extent practicable,
efforts will be made to utilize stone materials that are similar to materials native to the
area.

Good morning Crystal
After in -office discussion, the DWR has concerns about this submittal. We ask that you look at the following:
• The proposed gabion basket design will likely result in down channel scour due to stormwater discharges and
the energy created by a —8 foot drop in channel elevation.
• The proposed backfilled channel will essentially create an 80 foot long riffle, utilizing rip -rap as a channel bed
material. There is no included proposed channel cross - sectional detail. Utilizing large rock (compared to a
natural channel of similar dimension and drainage area) will likely result in storm flow energy being dissipated
by those erosive velocity vectors not being able to move bedload, will scour the adjacent stream banks, resulting
in instability.

We ask that you evaluate the following alternative design ideas:
• Constructing a rock cross vein immediately below the existing gas line, which would have a sma Ile rstep down
to the channel reach below,( reducing the potential energy scour below the structure). (This maybe a
traditional cross vein, or a step tiered structure such as an "A" vein to help deal with storm flow energy)
• Utilizing a " reference" stone size for any resultant backfilled channel as to provide a "natural bedload"
substrate to mimic natural processes such as bedload movement during storm events.
Please include these discussions as part of any response you prepare for the issued Request for Additional information.
Thank you,
Kevin and Andrew

Yes, we usually request a letter that the property owners are aware or the activity being done on their property.
This is usually a copy of the certified letter sent.
If the activity will only occur only on the easement or right of way then the gas company will be the responsible party,
From your initial project design it appeared that work may be done on the easement and on the neighboring
property. In that case we would include the property owner.
However, After the on -site meeting it sounded like you will be staying in the easement right of way so we would issue
the 401 to the gas company.
Hope this all clears any questions up.
Let me know if you have any additional questions.
Have a good weekend.

see Tony's email below which states he talked to the
property owners and they are aware of the project. we do not have a typical letter
we send to
people in situations like this. on larger projects we have land agents who deal
with everything,
as you know. But for something such as this we just have verbal communications
since it is

I spoke with Mrs. Condon on Monday Dec 15th about the work to be done in her front.
yard. Her and her
husband had looked at both options and had a few questions. we discussed both
options and she
settled on concept 2 version 1 , the concrete box with the culvert. I explained to
her too the best of my
ability what it would look like and that we would have to use it as access to our
ROW. she fully
understood and agreed that the box with the culvert would be the best way to go.
she was really more
worried about us cutting down her Hemlock tree than anything. I also emphasized
that all the work
would stay on our existing ROW , and that the regulator station would be moved but
would still be
within the 50ft ROW just over to one side to allow access . she was very
understanding and just wanted
us to keep them in the loop if anything changed. If you have any more questions just
give me ring.
