Dear Mr. Setzer:
On September 27, 2011, 1 inspected the construction work for the new bridge over the Nantahala River on US
Highway 19-74 in Swain County. Work was underway on the western bent in the river. Sediment and erosion
control structures appeared to be working properly with no sediment loss to the Nantahala River.
Please ensure that all sediment and erosion control structures are maintained and that seeding and mulching are
performed as needed to protect State surface waters. A copy of the inspection report is attached to this letter.
If you have questions, please call me at 828-296-4500.

Work is underway to complete the construction of the western bent in the river. The bent on the east side has
been completed. Beams should be set over the river in the next week or so. Contractor is trying to complete all
work in or over the river by October 15.

Continue to maintain erosion control devices and continue with seeding, matting and mulching as required to
protect State surface waters.
