Delegation Agreement with SCC and NCDENR
25, 1991 the NC Sedimentation Control Commission (SCC) granted
the authority to the NCDOT to administer its own Sediment and
Erosion Control Program within the jurisdiction of its
Division of Land Quality with NC Department of Environment
and Natural Resources (NCDENR) reviews the NCDOT's program on
an annual basis. Land disturbing activities within the NCDOT
must be in compliance with the
Sedimentation and Pollution Control Act (SPCA) of 1973.
Mandatory Standards of SPCA
Erosion Control (EC) Plan required for disturbance of one acre
must be provided along natural watercourses with "sufficient
width to confine visible siltation within the 25% of the
buffer zone nearest the land-disturbing activity." Trout
waters require an "undisturbed buffer zone 25 feet wide."
"The angle for
graded slopes and fills shall be no greater than the angle
which can be retained by vegetative cover or other adequate
erosion-control devices or structures."
exposed will, within 21 calendar days of completion of any
phase of grading, be planted or otherwise provided with
temporary or permanent ground cover, devices, or structures
sufficient to restrain erosion."
The land-disturbing activity shall be
conducted in accordance with the approved erosion and
sedimentation control plan.
Inspection Process and Grading System
and Maintenance projects are reviewed on a monthly basis to
check for compliance with SPCA. These inspections will be done
by either the Roadside Environmental Field Operations Engineer
or Technician. A report is filled out discussing any comments
or actions that may need to be addressed. The four areas that
are concentrated on are Installation, Maintenance and
Effectiveness of the EC measures, and Plan Implementation.
Then an overall grade is given. The grading scale is a
follows: 10-Excellent, 9-Very Good, 8-Good, 7-Fair, 6 or below
If the Field
Operations Engineer or Technician gives a project an overall
grade of 6 or below, the project will receive an Immediate
Corrective Action (ICA). When an ICA is issued the District or
Resident Engineer must respond and begin corrective actions
within 24 hours. It is recommended that grading operations be
suspended until the ICA is lifted. The Field Ops personnel
will revisit the site within 5 working days or 7 calendar days
(whichever is shorter) and review the site to see if
appropriate actions were taken. At this time the ICA will
either be lifted or continued.
A NOV is a
Notice of Violation given by the Land Quality Section of
NCDENR for projects that are out of compliance with the SPCA
1973. Corrective actions should be taken immediately to
resolve the NOV.

equipment in streams, lack of perimeter measures, etc.)
