Subject: Woody Mill Interchange Project R-2612A
Guilford County
DWQ No: 20(Dg1070
Dear Mr. Smith:
On September 27, 2011, Amy Euliss, Division of Water Quality (Division) regional staff conducted a site visit
following the discovery by NCDOT staff, of sediment in jurisdictional streams and a wetland on the Woody Mill
Interchange Project in Guilford County. The site visit was in conjunction with yourself, and other NCDOT and
contractor staff. During the site visit, it was noted that a sediment loss had occurred as a result of a failed silt fence
and rock silt screens. These failures occurred as a result of approximately six inches of rain falling over the
weekend. The loss of sediment is a violation of 15A NCAC 02B.0211 (3)f.
The fill of ajurisdictional wetland without authorization is a violation of Title 15A NCAC 2B .0231(a) and (b) (1)
and (5).
Upon discovery; NCDOT quickly contacted the Division to report the sediment and seek clean up recommendations.
As a result of the site inspection, one wetland and two streams received sediment. The stream at culvert site 6
received sediment and 57 wash stone. Accumulates did not warrant clean-up. The stream and wetland complex
associated with the borrow site also received sediment. Once the stream clears up, if accumulated sediments in the
stream channel are greater than a thin film, then they shall be removed. As for the wetland, it was determined that
accumulated sediment greater than a thin film are to be removed from the wetland by hand allowing very few
workers in the wetland at one time to reduce disturbance to the vegetation.
During the inspection, the NPDES Construction Stormwater Records were reviewed. The records need some
addition information; however they were deemed compliant. The Division would like to commend NCDOT
Division 7 for their prompt response to this matter. The Division appreciates the time NCDOT staff spent
discussing the site, and the immediate response taken by NCDOT. We look forward to continued communication
and assistance on this, and future projects. If you have any questions or comments, please do not hesitate to contact
Amy Euliss at 336-771-4959 or at amy.euliss@ncdenr.gov.
Sincerely,
W. Corey Basinger
