NCDENR Self Inspection Program for
Erosion and Sedimentation Control
Effective October 1, 2010, persons conducting land disturbing activities larger than one
acre must inspect their project after each phase of the project, and document the
inspection in writing.
1. The financially responsible parry, landowner or their agent may conduct the inspection.
2. All erosion and sedimentation control mealsures, including sedimentation control basins, sedimentation traps,
sedimentation ponds, rock dams, temporwy diversions, temporary slope drains, rock check dams, sediment
fence or barriers, all forms of inlet pro , storm drainage facilities, energy dissipaters, and stabllization
methods of open channels must be inspected.
3. The need for ground cover should also be checked. Temporary or permanent ground cover must be
provided on graded slopes and fi1s *Min
21 calendar days of the cam eton of a
phase of grading.
Permanent ground cover must be provided within 15 working days or 90 calendar days (60 days in HOW
zones), whichever term is shorter, upon the completion of construflion or development.
4. The actual dimensions (length and width of the basins have to be checked, usually with a tape measure, and
compared to the dnensions on the approved plan. Only relative elevations, compau3ng the bottom and top
elevations are necessary.
5. A significant deviation means an omission, alteration or relocation of an erosion or sedimentation control
measure that prevents the measure froth pert rming as intended. if the approved erosion and sedimentation
control pien canot be followed, a revised plan should be submiitted for review.
6. Use the *gWSelflnspection Report for Land Disturbing Activity as Required by NCGS 113A 64.1" h can
be completed by hand or completed as din Excel spreadsheet. An aitemative is to make notations on the
copy of the approved erosion and sedinentaWn control plan that is kept on the project sine. Rule 15A
NCAC 04B. 0131 states that° documentation shall be acoomplished by initialling and dating each measure
or practice shown on a copy of the approved brosion and sedimentation control plan or by completing, dating
and signing an inspection report that Ift each measure, practice or device shown on the approved erosion
and sedimentation control plan."
7. NPDES Self Monitoring Report may only be used to report that the maintenance and repair requirements for
all temporary and permanent erosion and sedimentation control measures, practices and devices have been
pertbrnied.
a. Unlike the NPDES Self Monitoring Report, the Self Inspection Report foF Land Disturbing Activity does not
have to be weekly. Rather, this report it completed after each phase of th e approved erosion and
sedimentation control plan is complete .' Not every project will have all the passible phases, but the fist of
phases includes the following:
Installation of perimeter erosion �ndl sediment control measures;
Clearing and grubbing of existing, grouted cover;
Completiion of any phase of graft of slopes or fills;
Inst811fation of storm drainage factifies;
Completion of construcoon or deveopment:
Estab0shment of permanent ground cover sufficient to restrain erosion.
9. Do not mail the report. The records mutt be made available to the erosion control inspector at the site. Arty
documentation of inspections that occur on a copy of the approved erosion and sedimentation control plan

HOW ,Zones)
*"Extensions of time may be opproved by the permitting outhority base
on weather or other site -specific conditions that make compliance
impracticable." (Section Il.b (2)(6))
1. Plocement and upkeep of rain gauge on site that must be monitored
throughout the course of the project,
2. The contractor shall keep a log of all rainfall events, erosion
control activities, and inspections throughout the course of the
project. This log must be kept on site at oil times and be
available for inspection
3. The contractor sholl inspect all erosion control measures in
accordance with the NPDES requirements. A minimum inspection
schedule of weekly and with in 24 hours after every significant {1/2 inch
or more) rainfall event (obtain copy of the permit for this project for
details.)
B.) INSPECTIONS
1. Inspection reports must be available on -site during business hours
unless a site -specific exemption is opproved.
2. Records must be kept for 3 yeors and ovoilable upon request.
C.) BUILDING WASTE HANDLING
1. No paint or liquid wastes in stream or storm drains.
2. Dedicated areas for demolition, construction and other wastes located
50' from storm drains and streams unless no reasonable alternatives are
ovailable.
3. Earthen -material stockpiles located 50' from storm drains unless no
reasonable altemative available.
4. Concrete materials must be controlled to ovoid contact with surface
waters, wetlands, or buffers.
Construction I- Clear the area of all debris that might finder excavation and disposal of
Specifications sp°iL
2. Install the rClass B or Class I ripmp in a semi -circle around the pipe
inlet The stone should. be built UP higher on each end where it ties into the
embank=nt.. Themir Mum:crest width of the riprap should:be 3 feet, with a
minimum bottom widtih.of 11 feet: The minirnwn height should be 2 feet, but
also 1 foot lower than the shoulder of the embankment or diversions.
3. A I foot thick layer of NC DOT #5 or #57 stone should_be placed on the
outside slope of the tiptop.
4. The. sediment storage area should be excavated around the outside of the
stone horseshoe 18 inches below natural grade.
5. When the contribudug drainage area has been stabiEwd, fill depression
and establish find grading elevations, compact area properly, and stabilize
with ground coEyer.
Maintenance inspect rock pipe inlet protection at least weekly and after each significant (E/,
inch or greater) mdnfa U event aad repair immediately. Remove sediment and
restore the sediment storage area: to its original dimensions when the sediment
has accumulated to one-half tale. design depth of the trap. Place the sedirnwt
that is removed in the designated disposal area and replace the contaminated
part o.fthe gravel facing.
Check the structure fordamage. Any riprap displaced from the stone. horseshoe
.must be replaced immediately -
After all the sedimeniVoducing areas have been permanently stabilized,
remove the structure and all the unstable sediment. Smooth the area to
blend with the adjoining areas and. provide permanent ground cover (Surface
Stabilisation)_
