Self Inspection and Reporting Requirements
Minimum self -inspection and reporting requirements are as follows unless otherwise approved in writing by the Division of
Water Quality.
a) A rain gauge shall be maintained in good working order on the site unless another rain -monitoring device has been
approved by the Division of Water Quality.
b) A written record of the daily rainfall amounts shall be retained and all records shall be made available to Division of
Water Quality or authorized agent upon request. If no daily rain gauge observations are made during weekend or holiday
periods, and no individual -day rainfall information is available, the cumulative rain measurement for those un -attended
days will determine if a site inspection is needed. (Note: if no rainfall occurred, the permittee must record "zero")
c) Erosion and sedimentation control measures shall be inspected to ensure that they are operating correctly. Inspection
records must be maintained for each inspection event and for each measure. At a minimum, inspection of measures must
occur at the frequency indicated below:
i) All erosion and sedimentation control measures must be inspected by or under the direction of the permittee at least
once every seven calendar days, and
ii) All erosion and sediment control measures must be inspected by or under the direction of the permittee within 24
hours after any storm event or greater than 0.50 inches of rain per 24 hour period.
d) Once land disturbance has begun on the site, stormwater runoff discharge outfalls shall be inspected by observation for
erosion, sedimentation and other stormwater discharge characteristics such as clarity, floating solids and oil sheens.
Inspections of the outfalls shall be made at least once every seven calendar days and within 24 hours after any storm event
of greater than 0.50 inches of rain per 24 hour period.
e) Inspections are only required to be made during normal business hours. When adverse weather conditions would cause
the safety of the inspection personnel to be in jeopardy, the inspection can be delayed until I tis deemed safe to perform
these duties. (Times when inspection were delayed because of safety issues should be noted in the Inspection Record). If
the inspection cannot be done on that day, it must be completed on the following business day.
f) Twenty-four House Reporting for visible sediment deposition
i) The permittee shall report to the Division of Water Quality central office or the appropriate regional office any visible
sediment being deposited in any stream or wetland or any noncompliance which may endanger health or the
environment. (See Section VIII of this permit for contract information.) Any Information shall be provided orally or
electronically within 24 hours from the time the permittee became aware of the circumstances.
ii) A written submission shall be provided to the appropriate regional office of the Division of Water Quality within 5 days
of the time the permittee becomes aware of the circumstances. The written submission shall contain a description of
the sediment deposition and actions taken to address the cause of the deposition. The Division of Water Quality staff
may waive the requirement for a written report on a case-by-case basis.
g) Records of inspections made during the previous 30 days shall remain on the site and available for agency inspectors at all
times during normal working hours, unless the Division of Water Quality provides a site-specific exemption based on unique
site conditions that make this requirement not practical. Older records must be maintained for a period of three years after
project completion and made available upon request. The records must provide the details of each inspection including
observations, and actions taken in accordance with this permit. The permittee shall record the required rainfall and
monitoring observations on the Inspection Record form provided by the Division or a similar inspection form that is inclusive
of all of the elements contained in the Division's form. Use of electronically -available records, in lieu of the required paper
copies for inspection will be allowed if shown to provide equal access and ut8ility as the hard -copy records.
h) Inspection records must include, at a minimum, the following:
i) Control Measure Inspections: Inspection records must include at a minimum: 1) identification of the measures
inspected, 2) date and time of the inspection, 3) name of the person performing the inspection, 4) indication of
whether the measures were operating properly, 5) description of maintenance needs for the measure, 6) corrective
actions taken (7) date of actions taken, as well as the date and amounts of rainfall received.
ii) Stormwater Discharge Inspections: Inspection records must include at a minimum: 1) identification of the discharge
outfall inspected, 2) date and time of the inspection, 3) name of the person performing the inspection, 4) evidence of
indicators of stormwater pollution such as oil sheen, floating or suspended solids or discoloration, 5) indication of
visible sediment leavingthe site 6 actions taken to correct/prevent sedimentation and 7 date of actions taken.
) /P )
iii) Visible Sedimentation Found Outside the Site Limits: Inspection records must include: 1) an explanation as to the
actions taken to control future releases, 2) actions taken to clean up or stabilize the sediment that has left the site
limits and 3) the date of actions taken.
iv) Visible Sedimentation Found in Streams or Wetlands: All inspection should include evalu7ation of streams or wetlands
onsite or offsite (where accessible) to determine if visible sedimentation has occurred.
i) Visible Stream Turbidity - If the discharge form a site results in an increase in visible str4eam turbidity, inspection records
must record that evidence and actions taken to reduce sediment contribution. Sites discharging to streams named on the
state's 303(d) list as impaired for sediment -related causes may be required to perform additional monitoring, inspections or
application of more -stringent management practices if it is determined that the additional requirements are needed to assure
compliance with the federal or state impaired -waters conditions. If a discharge covered by this permit enters a stream
segment that is listed on the Impaired Stream List for sediment -related causes, and a Total Maximum Daily Load (TMDL) has
been prepared for those pollutants, the permittee must implement measures to ensure that the discharge of pollutants from
the site is consistent with the assumptions and meets the requirements of the approved TMDL. The Division of Water Quality
303(d) list can be found at: http://h2o.enr.state.nc.us/tmdl/General_303d.htm/

the DIPRA brochure "Truck Loads on Pipe Buried at Shallow Depths."
a Ductile Iron Pipe is adequate for the rated working pressure indicated for each nominal size plus a surge
allowance of 100 psi. Calculations are based on a 2.0 safety factor times the sum of working pressure and 100
psi surge allowance. Ductile Iron Pipe for working pressures higher than 350 psi is available.
b An allowance fora single H-20 truck with 1.5 impact factor is include for all depths of cover.
c Calculated maximum depth of cover exceeds 100 feet.
d Minimum allowable depth of cover is 3 feet.
e For pipe 14 inches and larger, consideration should be given to the use of laying conditions other than Type 1,

CONSTRUCTION SPECIFICATIONS
1. KEEP CLEARING AND EXCAVATION OF THE STREAM BANKS AND
BED AND APPROACH SECTIONS TO A MINIMUM.
2. DIVERT ALL SURFACE WAER FROM THE CONSTRUCTION SITE
ONTO UNDISTURBED AREAS ADJOINING THE STREAM.
3. KEEP STREAM CROSSINGS AT RIGHT ANGLES TO THE STREAM
FLOW.
4. STABILIZE ALL DISTURBED AREAS SUBJECT TO FLOWING
WATER, INCLUDING PLANNED OVERFLOW AREAS, WITH RIPRAP
OR OTHER SUITABLE MEANS IF DESIGN VELOCITY EXCEEDS
THE ALLOWABLE FOR THE IN-PLACE SOIL.
5. ENSURE THAT BYPASS CHANNELS NECESSARY TO DEWATER
THE CROSSING SITE ARE STABLE BEFORE DIVERTING THE
STREAM. UPON COMPLETION OF THE CROSSING, FILL,
COMPACT, AND STABILIZE THE BYPASS CHANNEL
APPROPRIATELY.
6. REMOVE TEMPORARY STREAM CROSSING IMMEDIATELY WHEN
THEY ARE NO LONGER NEEDED. RESTORE THE STREAM
CHANNEL TO ITS ORIGINAL CROSS-SECTION, AND SMOOTH
AND APPROPRIATELY STABILIZE ALL DISTURBED AREAS.
7. ANY IN -STREAM SEDIMENT CONTROL MEASURES MUST BE
REMOVED UPON STABILIZATION OF THE AREA.
MAINTENANCE
INSPECT TEMPORARY STREAM CROSSINGS AFTER
RUNOFF -PRODUCING RAINS TO CHECK FOR
BLOCKAGE IN CHANNEL, EROSION OF ABUTMENTS,
CHANNEL SCOUR, RIPRAP DISPLACEMENT, OR
PIPING. MAKE ALL REPAIRS IMMEDIATELY TO
PREVENT FURTHER DAMAGE TO THE INSTALLATION.

INSTALLATION NOTES:
1. REFER TO "NORTH CAROLINA DIVISION OF FOREST RESOURCES" LITERATURE, INSTALLATION
MAINTENANCE GUIDELINES, & "NORTH CAROLINA FORESTRY BMP MANUAL -2006".
2. USE A BULLDOZER, KNUCKLEBOOM LOADER, OR SKIDDER TO INSTALL & REMOVE DRAGLINE MATS.
3. KEEP HEAVY EQUIPMENT OUT OF STREAM.
4. INSTALL WATER DIVERSION DEVICES (WATER BARS, TURNOUTS, BROAD-BASED DIPS, ETC.) ON
BOTH SIDES OF THE MATS.
5. STABILIZE EXPOSED MINERAL SOIL WITH TREE TOPS OR BRUSH DURING MAT INSTALLATION, AND
SEEDING/MULCH AFTER MAT REMOVAL.
6. INSTALL MATS TO CREATE A MINIMUM TEN FOOT BRIDGE WIDTH.
MAINTENANCE NOTES:
1. KEEP MATS' SURFACE FREE OF MINERAL SOIL AND DEBRIS THAT COULD ENTER STREAM.
2. PERIODICALLY CHECK MAT HARDWARE; RETIGHTEN NUTS & CABLE CLAMPS AS NECESSARY TO
MAINTAIN BRIDGE STRENGTH AND INTEGRITY.
3. IMMEDIATELY REMOVE ANY DEBRIS WHICH ENTERS THE STREAM AT THE CROSSING LOCATION.
REMOVAL NOTES:
1. CLEAN OFF BRIDGE SURFACE.
2. REMOVE MATS BY USING MAT CABLE LOOP OR SKIDDER GRAPPLE.
3. PERMANENTLY STABILIZE DISTURBED PORTIONS OF STREAM BANK AND APPROACH ROADS WITH
PERENNIAL GRASSES/MULCH (OR WETLAND MIX WHEN APPLICABLE).
4. LEAVE APPROPRIATE WATER DIVERSION STRUCTURES IN PLACE ON BOTH SIDES OF STREAM.

2. USE 2' WOODEN STAKES WITH A 2" NOMINAL CROSS SECTION.
3. INSTALL A MINIMUM OF TWO UP SLOPE STAKES AND 4 DOWN SLOPE STAKES
AT AN ANGLE TO WEDGE WATTLE TO EXISTING GRADE.
4. PROVIDE STAPLES OF 0.125" DIAMETER STEEL WIRE FORMED INTO A U
SHAPE NOT LESS THAN 6" IN LENGTH.
5. INSTALL STAPLES APPROXIMATELY EVERY 1 LINEAR FOOT ON THE UP SLOPE
SIDE OF THE WATTLE AND AT EACH END TO SECURE IT TO THE SOIL.
MAINTENANCE:
1. WATTLES SHOULD BE CHECKED AND CLEARED OF ACCUMULATED DEBRIS AND
SEDIMENT.
2. REPLACE AS REQUIRED.

NOTES:
1. EXCAVATION SHALL BE PERFORMED IN ONLY DRY SECTIONS OF
CHANNEL UNLESS DRAINAGE AREA EXCEEDS 6 SQUARE MILES.
2. IMPERVIOUS DIKES SHOULD BE USED TO ISOLATE WORK AREAS
FROM STREAM FLOW.
3. THE CONTRACTOR SHALL NOT DISTURB MORE AREA THAN CAN BE
STABILIZED IN ONE WORKING DAY.
4. EACH PUMP AROUND PUMP SHOULD ADEQUATELY CONVEY BASE
FLOW VOLUMES.
SEQUENCE OF CONSTRUCTION FOR TYPICAL PUMP AROUND
1. INSTALL SPECIAL STILLING BASINS AT THE DOWNSTREAM END OF
THE DESIGNATED PROJECT WORKING AREA.
2. THE CONTRACTOR WILL INSTALL THE PUMP AROUND PUMP AND THE
THE TEMPORARY PIPING THAT WILL CONVEY THE BASE FLOW FROM
UPSTREAM OF THE WORK SITE TO THE SPECIAL STILLING BASIN.
3. INSTALL UPSTREAM IMPERVIOUS DIKE AND BEGIN PUMPING
OPERATIONS FOR STREAM DIVERSION.
4. INSTALL THE DOWNSTREAM IMPERVIOUS DIKE AND PUMPING
APPARATUS IF NEEDED TO DEWATER THE ENTRAPPED AREA. THE
PUMP AND HOSE FOR THIS PURPOSE SHALL BE OF SUFFICIENT SIZE
TO DEWATER THE WORK AREA. THIS WATER WILL ALSO FLOW INTO
A SPECIAL STILLING BASIN.
5. THE CONTRACTOR WILL PERFORM STREAM RESTORATION WORK IN
ACCORDANCE WITH THE PLAN AND FOLLOWING THE GENERAL
CONSTRUCTION SEQUENCE.
6. THE CONTRACTOR WILL EXCAVATE ANY ACCUMULATED SEDIMENT
AND DEWATE BEFORE REMOVAL OF THE IMPERVIOUS DIKE. REMOVE
IMPERVIOUS DIKES, PUMPS, AND TEMPORARY FLEXIBLE HOSE/PIPING
STARTING WITH THE DOWNSTREAM DIKE FIRST.
