OK, thanks.

William, if you can be sure that the appropriate monitoring requirements are going to be in the permit (as I
recommended in my 4/7/09 letter), then I will have no more significant comments on the PN for U-3826.
Thanks for the opportunity to comment. Have a good weekend,

hi Kathy
The drawings just show the area of wetland restoration. We survey the adjacent wetland for elevations and
use that to set the target elevations in the restoration area.

I agree with the proposed ratios (1:1 for on-site and 3:1 for Mildred Woods). How can we ensure that the
target wetland elevations will be reached based on the drawings in the permit application?
Thanks,

Subject U-3826 Comments from EPA
Hi Kathy
We received your comments on U-3826, Daniels Street Extension, dated April 7, 2009. Your letter references
the mitigation proposal from the public notice. There was a correction made to the acres of onsite and offsite
mitigation in a permit modification dated March 17, 2009. The permit modification proposed to offset the 1.48
acres of wetland impact at a 1:1 ratio with onsite mitigation of 0.86 acres of wetland restoration along with a
0.62 acre debit from Mildred Woods mitigation site.
NCDOT maintains its proposal for a1:1 ratio for the onsite mitigation. Onsite mitigation was discussed at
several field and office meetings on this project and no objections were raised. Furthermore, onsite mitigation
is ecologically beneficial by replacing wetland functions at the impact site. The site will be graded to the targe
wetland elevations, not the elevations along the edge of the wetland. As with all NCDOT onsite mitigation, the
site will be purchased fee simple, signed along the boundary, and placed on the NEU Mitigation
GeoDatabase. Our monitoring protocols include annual reporting and agency review for interim success as
well as final review and closeout. These are standard practices on all onsite mitigation projects so the
language is not repeated in the site mitigation plan as an effort to reduce paperwork and redundancy.
NCDOT reviewed the Mildred Woods mitigation site documents. The site was planned and constructed as a
non-riverine wetland site. When all NCDOT sites were transferred at the inception of EEP, this site was
placed in the riparian catergory, which caused the confusion with this debit. The debit ledger has been
revised to reflect the non-riverine status of the site and to provide a 3:1 ratio debit for 0.62 acres of impacts
from this roadway project. A copy of the revised debit from Mildred Woods site is below.
