Sorry, I did not see the first email on this.
Since there is no additional permanent impacts, and simply a minor change in how those
impacts are handled, I will not issue a modification but a Correction Letter to the last one.
I'll send it out ASAP and fax you a copy.

Any decide here yet? If so let me know ASAP. If you've issued a modification already -
thanks, please fax this to me at [phone]. If hard copies are necessary first, please
let me know so I can get this in the mail.

Rob:
Reference: Neuse Buffer Authorization (DWQ Project No. 20090650 and 20090650 ver. 2).
USACE NWP 14 non-reporting, not issued.
The North Carolina Department of Transportation (NCDOT) has State Project No. 41995.1 under
contract and work at Little Black Creek on Old Stage Road just south of Barbour Store Road is
currently underway. Staking for the headwall construction revealed a conflict with the
proposed edge of pavement and proposed shoulder improvements above the pipe inlet. Due to the
angle of the headwall (which matches the angle of this cross line pipe); if built as planned,
this concrete would touch the edge of pavement. Which would cause a safety concern at a site
where we are trying to eliminate safety concerns. Additionally it was observed that the last
joint on the outlet end of this cross line is disconnected, causing a sink hole in the
pavement above. Left as is any pavement overlay would eventually crack and sink too (picture
969 inlet, picture 973 outlet).
To address these two issues, we propose (see attached permit):
1)At the pipe inlet, add two joints of pipe and construct the headwall at face of the second
joint.', This would give room for shoulder improvements and slight lane widening and will put
the concrete headwall further off the proposed edge of pavement.
2)At the pipe outlet, reset disconnected end joint and add one additional joint. This would
fix the sink hole issue and better allow for proposed shoulder improvements.
The permit currently covers buffer and stream impacts out to the right-of-way limits. The
stream impacts include 431ft of bank stabilization with concurrent dewatering (17ft RR at
inlet,'26ft RR at outlet) with no surface water fill. The changes listed above would still
total impacts of 431ft, but it would be broken down as follows: (8ft SW fill and 9ft of RR at
(inlet) and (4ft SW fill and 22ft of RR at the outlet). As this is the third version of
presented project impacts, you can see that every effort to minimize has been exhausted.
First with only buffer impacts, then with only a headwall, and now a proposal which includes
only minimal surface water fill.
To modify the Buffer Authorization/WQC 3820 to break out proposed surface water fill from the
RR stabilization - what do you need? Do you need 5 new sets with revised PCNs? I can do this,
but I just need your help in turning this approval around quickly so I wanted to email these
details ahead of any formal transmittal. Thanks.
