Good evening Amy,
I've attached the updated sheets for the HEMC Substation project per your comments and Andrea Leslie's
I've specified that the erosion control matting is to be free of plasting.
I've added live staking to the riparian area.
I've added a riparian seed mix to the riparian area.
Please let me know if anything else is needed.
Thanks for your help,
Gregory Hoffman, PE

G reg,
I just want to summarize our phone conversation from yesterday.
I asked about avoidance and minimization of the crossing and whether the existing crossing at the entrance to the
substation could be utilized for the mobile transformer. You informed me that the mobile transformer is transported on
a long trailer that has a turning radius that is incompatible with the layout within the existing substation. Thus, a new
crossing is needed to position the mobile transformer adjacent to the existing substation.
I also inquired about the use of erosion control matting at the stream crossing. Any matting applied to the streambanks
should be free of any plastic netting or mesh. If any matting will be used along streambanks, please add this specification
to the plan set.

One additional item that DWR will need clarification on is the PCN signature of Jacob Jones. He is not listed as the
applicant or owner in the application. Can you clarify his relationship to HEMC?
The PCN Help Document states:
Applicant/Agent's Signature and Date — The applicant should print their name in the first block, then sign and date. NC
15 NCAC 2H .502(f) reads as follows: "Who Must Sign Applications. The application shall be considered a "valid
application" only if the application bears the signature of a responsible officer of the company, municipal official, partner
or owner. This signature certifies that the applicant has title to the property, has been authorized by the owner to apply
for certification or is a public entity and has the power of eminent domain. Said official in signing the application shall
also certify that all information contained therein or in support thereof is true and correct to the best of his/her
knowledge."
Note: The signature cannot be an electronic signature. If an agent is signing for the owner, an agent authorization letter
must be attached. A sample authorization letter is available on the Corps web site.
Thank you,

1. PREPARE SOIL BEFORE INSTALLING BLANKETS, INCLUDING ANY NECESSARY APPLICATION OF LIME, FERTILIZER, AND SEED.
NOTE: WHEN USING CELL-O-SEED DO NOT SEED PREPARED AREA. CELL-O-SEED MUST BE INSTALLED WITH PAPER SIDE DOWN.
2. BEGIN AT THE TOP OF THE SLOPE BY ANCHORING THE BLANKET IN A 6" (15cm) DEEP X 6" (15cm) WIDE TRENCH
WITH APPROXIMATELY 12" (30cm) OF BLANKET EXTENDED BEYOND THE UP -SLOPE PORTION OF THE TRENCH. ANCHOR THE
BLANKET WITH A ROW OF STAPLES/STAKES APPROXIMATELY 12" (30cm) APART IN THE BOTTOM OF THE TRENCH.
BACKFILL AND COMPACT THE TRENCH AFTER STAPLING. APPLY SEED TO COMPACTED SOIL AND FOLD REMAINING 12" (30cm)
PORTION OF BLANKET BACK OVER SEED AND COMPACTED SOIL. SECURE BLANKET OVER COMPACTED SOIL WITH A ROW OF
STAPLES/STAKES SPACED APPROXIMATELY 12" (30cm) APART ACROSS THE WIDTH OF THE BLANKET.
3. ROLL THE BLANKETS (A.) DOWN OR (B.) HORIZONTALLY ACROSS THE SLOPE. BLANKETS WILL UNROLL WITH APPROPRIATE SIDE
AGAINST THE SOIL SURFACE. ALL BLANKETS MUST BE SECURELY FASTENED TO SOIL SURFACE BY PLACING STAPLES/STAKES
IN APPROPRIATE LOCATIONS AS SHOWN IN THE STAPLE PATTERN GUIDE. WHEN USING OPTIONAL DOT SYSTEM'" STAPLES/STAKES
SHOULD BE PLACED THROUGH EACH OF THE COLORED DOTS CORRESPONDING TO THE APPROPRIATE STAPLE PATTERN.
4. THE EDGES OF PARALLEL BLANKETS MUST BE STAPLED WITH APPROXIMATELY 2"-5" (5cm-12.5cm) OVERLAP DEPENDING
ON BLANKET TYPE. TO ENSURE PROPER SEAM ALIGNMENT, PLACE THE EDGE OF THE OVERLAPPING BLANKET (BLANKET BEING
INSTALLED ON TOP) EVEN WITH THE COLORED SEAM STITCH -ON THE PREVIOUSLY INSTALLED BLANKET.
5. CONSECUTIVE BLANKETS SPLICED DOWN THE SLOPE MUST BE PLACED END OVER END (SHINGLE STYLE) WITH AN APPROXIMATE
3" (7.5cm) OVERLAP. STAPLE THROUGH OVERLAPPED AREA, APPROXIMATELY 12" (30cm) APART ACROSS ENTIRE
BLANKET WIDTH.
NOTE:
*IN LOOSE SOIL CONDITIONS, THE USE OF STAPLE OR STAKE LENGTHS GREATER THAN 6" (15cm) MAY BE NECESSARY TO
PROPERLY SECURE THE BLANKETS.
