Subject U 4007B Complaint and Non Compliance
Dear Ms Henson
EUGENE A CONn 7R
SECRETARY
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 Unauthonzed Discharge
The Contractor repaired the borrow pit s dewatermg 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 dewatermg 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
dewatermg 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
