River Basin in conjunction with the proposed development will not result in a violation of applicable Water Quality
Standards and discharge guidelines. Therefore, the State of North Carolina certifies that this activity will not
violate the applicable portions of Sections 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in
accordance with the application and conditions hereinafter set forth. Should your project change, you are required

Eric and Rob,
I had the opportunity to discuss this issue w/ the.hydro engineer for the project. He
modified a portion of the wetland/stream permit drawing (Permit Drawing 12 of 19) to
highlight the area associated with the sewer line relocation. This revision is attached to
this email as the following: u-4703_hyd_prm_wet_rev0910.pdf The drawing is-rather busy due
to the other information contained in the drawing. However, I have taken this drawing and
added information which should help you in your review. This drawing is attached to this
email as the following: U-4703 new sewer line info.jpg
The following information describes the changes to jurisdictional wetland impacts in the'.
proposed work area for the sewer line relocation:
-A portion of the larger proposed work area is in the permanent fill slope: and.•has. been

Subject: Construction issue on Timber Drive Extension (U-4703) in Wake County
Re:
Construction of Timber Drive Extension (SR 2812) from NC 50 to White Oak Road in Garner TIP
No. (U-4703) -USACE Action ID No. 200520126 (DA#2004-20126) -NCDENR-DWQ Project No. 20100015
Eric and Rob,
The Department has previously received permits for construction of this project. Impacts
associated with relocation of a sewer line were permitted as part of the overall project
using NWP 14. The impacts associated with this activity were permitted in a very narrow,
small band of fill in wetland (approximately 8 feet wide) that is shaped like an upside down
"T". This is identified in the attached drawing: U-4703 View 1. Note that relocation of the
sewer line was permitted as fill in wetlands; however, the impacts are more accurately
described as excavation in wetland and then backfilling with suitable material.
The impacts associated with this activity do not appear to have been adequately identified or
quantified in the permit application and on this permit drawing. Note that the relocated
sewer line is 10 feet deep. Conversations with the RE office and contractor indicate the
following:
-Relocation of a 10 feet deep sewer line requires a significant amount of construction area.
It cannot be conducted in an 8 feet wide area.,
-Construction"equipment used to relocate the sewer line is 9 feet wide.!-:The trench box:"and
man-hole shield '(for "the excavation to install-the line) are 7.5 feet wide and 12 feetrwide,
respectively. f<-;".c
-Additional impacts to'the-wetland are necessary to handle the spoil material and :material"
transfer.
Accordingly;:,a:larger-.work,area is requiredJor:this,a.ctivity.:.The contractor, has indicated.
that an approximately 40.,x 55 foot wide area (totaling 0.05 ac) in therwetland.is necessary
to do.this work. Construction equipment will work on mats as practical: The excayated area
will be backfilled with the original wetland material. The Department will;attemptsto
stabilize this area as close to possible to pre-existing conditions. This construction .
activity appears to be accurately described as temporary excavation/fill•:in wetland:,.
The proposed construction area is depicted in the attached drawing: U-4703; view 2:' This:
change in permitting will result in the "following:
-Increase in new temporary excavation/fill in wetland impacts -Change in temporary fill in
wetland impacts (for timber work pad) to temporary excavation/fill in wetland impacts -Change
in hand clearing in wetland impacts to temporary excavation/fill in wetland impacts -Change
in mechanized clearing in wetland impacts to temporary excavation/fill in wetland impacts
What is the best way to permit this construction revision? It might fall under NWP 14 with
notification with a PCN. However,.a PCN was previously supplied as part of the original
NCDOT permit application on December 30, 2009.
Thanks in advance for your input on this issue.
