Subject: U -4007B Complaint and Non - Compliance
Dear Ms. Henson
In response to your office's letter, dated May 7, 2012, the Department is submitting to you the items of
correction completed by our Contractor, as well as future actions that will be taken by the Department
and the Contractor to ensure the project's compliance with all environmental permits.
Actions to Correct Unauthorized Discharee:
The Contractor repaired the borrow pit's dewatering basin, removing the excessive sediment deposits
noted during your office's review of the site. They also repaired several exposed, erodible areas that had
been noted as needing attention at or beyond the perimeter of the pit. These areas were repaired and have
been properly seeded and mulched. The sediment deposits down the slope at the two tributaries were
removed by the Contractor's forces utilizing shovels and buckets.
Action taken to prevent further Unauthorized Discharge:
Future measures will include adding additional locations for NTU readings along the path of the borrow
pit's discharge to the pond, as well as checking the background readings of any water meeting the borrow
pit's discharge. The dewatering operation's NTU readings will be checked for compliance 30 minutes
after the operation starts and begins discharging. All readings will be recorded by the Contractor on a
dewatering log. The NCDOT is also taking and recording several checks a week to verify the
contractor's readings. The dewatering basin itself will be added as a stormwater discharge outfall during
our NPDES reviews. This will insure it is closely monitored for any maintenance requirements,
regardless of the NTU readings.
The Department will work diligently to prevent this error from occurring in the future. We have
discussed the importance of monitoring turbidity and preventing erosion at all locations along the project,

both with the Contractor's personnel and our own staff. I have emphasized to them that they continue to
look for ways to go beyond the minimum requirements when ensuring compliance with our permits and
ensuring the preservation of our surrounding environment.
