Notice of Violation X-0002 C NOV-2013-PC-0281
Dear Ms. Chapman:
This correspondence is in reply to your Notice of Violation dated August 7, 2013 for the
X-0002C project (Fayetteville Outer Loop).
On July 31, 2013, Mr. Herndon observed two sediment basins that had failed. The
sediment material from the two basins discharged into jurisdictional area within Permit Site #4
near Sta.-L-118+00 LT and -L-119+00 RT was removed by the Barnhill Contracting Company,
but was not reported to DWR. While the discharge was not reported for this area of the project,
the Division did overlook these discharges while still reporting discharges on other areas of the
project. For the months of June and July approximately 33 inches of rainfall was experienced on
the project. Many of the rainfall events were of a short duration, high intensity variety, i.e. 2
incres o��er 1 hour duration.
Barnhill Contracting Company and the NCDOT worked diligently to keep up with the
excessive amount of rainfall that fell during the two months. Several of the skimmer basins blew
out around the outlet pipe (which had become saturated), and water was flowing along the pipe
until it blew out the dam. We had committed 20 or more laborers with buckets to clean out the
sediment that was lost in the jurisdictional areas. We should point out that Barnhill did not
design the basins, or the capacity of the basins. Since this has liappened, we have tried to use
different fabrics on the outlet end of the basin to try and stop the infiltration of water along the
PVC outlet pipe.
Mr. Herndon noted that an excavator was conducting repairs to the outlet weir with no
erosion-measut�es in place to control the turbid water. It is our understanding that the existing silt
fence was knocked down and overcome with sediment when the basin blew out. We have
discussed this with our foreman and have told them that measures need to be in place prior to
fixing basins that are discharging turbid water.

Since this November, we have met with Mr. Herndon and NCDOT to discuss this matter
and talk about ways to prevent this in the future. Also, all areas have been mitigated and
stabilized.
If you should have any questions or additional comments, please call me at 252-823-1021.
Yours very truly,
BARNHILL CONTRACTING COMPANY
