Hello Bill,
Your email was forwarded to me by my supervisor, Kevin Rose. I am working on the environmental
documentation and permitting for the project. This email contains the information you requested.
Project Description: The Eastern Federal Lands Highway Division, of the Federal Highway
Administration (FHWA), in cooperation with the U.S. Fish and Wildlife Service (FWS) is preparing
plans for roadway improvements on Milltail Road and Milltail Road Bridge within the Alligator River
National Wildlife Refuge, Dare County, NC. Milltail Road is currently an 18' wide, two lane, gravel
road flanked by a manmade agricultural channel and wetlands. The road provides access for visitors
and staff to the central portion of the Refuge. Milltail Bridge provides access to a parking area used
by visitors to canoe or I<ayak in Milltail Creel<. The objective of the project is to improve a 0.8-mile-
long section of Milltail Road by raising the profile which would improve sustainability and resilience
in flood prone areas. Bridge work includes repair of exposed reinforcing steel with epoxy paint on
the bent caps, cleaning and resealing the expansion/relief joints, and filling areas that have subsided
beneath the abutment footing. These improvements will enhance safe travel on Milltail Road and
Milltail Bridge during and after high rain and wind events. Wetland impacts would be minimized by
reducing the roadway width from 18' to 12' to the extent possible. Any impacts to wetlands would
be mitigated in accordance with federal and state regulatory agency requirements. No significant
impacts to natural or cultural resources are anticipated. A copy of the project plans is attached.
Impervious Surface Summary: The existing roadway is 18' wide with an unpaved/aggregate
surface. Since the road profile will be raised, the embankments will need to be widened; however,
the roadway travel lanes will be reduced to only 14' with one pulloff area to allow vehicles traveling
in opposite directions to pass each other. Overall, the amount of impervious/aggregate surface will
be reduced due to the narrower travel lanes.
Stormwater Management Summary: The project includes extensive temporary Erosion and
sediment control measures to be used during construction. The area will be permanently stabilized
with riprap and/or vegetation. No additional permanent stormwater management features are
proposed. Due to the on-site conditions (water on both sides of the road), and desire to minimize
impacts to the adjacent wetlands, it would be difficult to enginaeer any addtioanl SWM features.
Permitting Overview: We have already received Erosion and Sediment Control Approval, including
NPDES. We are planning to submit the Joint Permit Application to receive US Army Corp 404 permit
and NCDEQ 401 Water Quality Permit. The project is exempt from CAMA. We intent to coordinate
with you to receive the Stormwater Management Permit. My assumption was that we would need
the Coastal Stormwater Permit, and I was planning on filling out and submitting the "Stormwater
Management Permit Application Form" , NCDEQfor # SWU-101 (October 31, 2013 version) along
with the attachments and $505 permit fee. I appreciate your effort to reach out to us to confirm

whether this is accurate. Please let me know what needs to be done.

Hey Kevin,
I received notice that this project requires a Sedimentation/Erosion Control
Plan approval; which triggers a stormwater review. My sw review will focus
primarily on proposed impervious areas & drainage/stormwater controls.
Please provide a brief project description by email. If you can attach a site
plan/details; that would be helpful in deciding the appropriate sw permit
option. Also, do you have a US Fish and Wildlife Service contact that may be
familiar with this project ? I will get back to you with any questions.
