This office has reviewed the subject erosion and sedimentation control plan sealed by David C.
Revoir, PE on June 6, 2019. We find the plan to be acceptable and hereby issue this letter of
approval. This letter of approval shall be valid for a period not to exceed twenty-four months or
the time required for the proposed construction activities, whichever comes first.
Please be advised that Section 801, Sub -section E12 of the City of Rocky Mount's Land
Development Code (hereinafter referred to as LDC) requires that a copy of the approved erosion
control plan be on file at the job site. Also, you should consider this letter the notice required by
the LDC, Section 802, Sub -section Q 1 of our right of periodic inspection to ensure compliance
with the approved plan.
The City of Rocky Mount's Sedimentation Pollution Control Program is performance oriented,
requiring protection of the natural resources and adjoining properties. If following the
commencement of this project, it is determined that the erosion and sedimentation control plan is
inadequate to meet the requirements of the Soil Erosion and Sedimentation Control Ordinance of
the City of Rocky Mount (Section 801 of the LDC, also NCGS 113A-51 through 66,) this office will
require revisions to the plan and implementation of the revisions to ensure compliance with the
Ordinance. Performance Reservations for this plan are included as part of this approval. The
[phone] 1 331 S. Franklin St.. PO Box 1180, Rocky Mount, NC 27BO2-1180 1 www.rDckyrnountnu.gov

developer is responsible for the control of sediment on -site. If the approved erosion and
sedimentation control measures prove insufficient, the developer must take additional steps
necessary to stop sediment from leaving this site. Each sediment storage device must be inspected
after each storm event. Maintenance and/or clean out, is necessary anytime the device is at 50%
capacity.
Please be aware that this approval is based in part on the accuracy of the information in the
Financial Responsibility/Ownership Form, which you have provided. You are required to file an
amended form if there is any change in the information included on the form. Also, please note
that this approval does not relieve the permittee of the responsibility to obtain any other Federal,
State, or Local approvals or permits. The responsible party may need to contact the appropriate
Federal, State, and Local agencies prior to beginning work. This approval does not permit the
construction of any impervious surface, nor does it allow for the placement of fill in any area for
which a floodplain development permit is required.
In addition, LDC Section 801-E10 requires that you notify this office of the proposed starting date
for this project. Your cooperation is appreciated, and we look forward to working with you on this
proj ect.
Also, this letter gives the notice required by G.S. 113A-61.1(a) of our right of periodic inspection
to insure compliance with the approved plan.
As of April 1, 2019, all new construction activities are required to complete and submit an
electronic Notice of Intent (NOI) form requesting a Certificate of Coverage (COC) under the
NCGO10000 Construction Stormwater General Permit. This form MUST be submitted prior to
the commencement of any land disturbing activity on the above named project. The NOI form
may be accessed at deq.nc.gov/NCGO1. Please direct questions about the NOI form to Annette
Lucas at Annette.lucaskncdenr.gov or Paul Clark at Paul. clarkkncdenr. gov.
After you submit a complete and correct NOI Form, a COC will be emailed to you within three
business days. Initially, DEMLR will not charge a fee for coverage under the NCGO 1 permit.
However, on or after May 1, 2019, a $100 fee will be charged annually. This fee is to be sent to
the DEMLR Stormwater Central Office staff in Raleigh.
Title 15A NCAC 413 .0118(a) and the NCGO1 permit require that the following documentation
be kept on file at the job site:
1. The approved E&SC plan as well as any approved deviation.
2. The NCGO1 permit and the COC, once it is received.
3. Records of inspections made during the previous 30 days.

Permit No. NCG010000
PART I — NCG01 PERMIT COVERAGE
This permit applies to all owners or operators of stormwater discharges associated with construction
activities such as clearing, grading, and excavation, that result in the disturbance of a land area greater
than or equal to one acre, or that are part of a common plan of development of that size or greater that
are also subject to the North Carolina Sedimentation Pollution Control Act of 1973 (SPCA). This
permit may also be issued to stormwater discharges from like activities deemed by the Division of
Energy, Mineral, and Land Resources (DEMLR) to be similar to these operations in process or
stormwater discharges. This permit shall not apply to land -disturbing activities that are covered under
the NCG020000 (Mining Activities) permit or the NCG120000 (Landfills) permit.
The SPCA requires that the persons engaged in subject construction activities develop and adhere to an
Erosion and Sedimentation Control (E&SC) Plan. The Sedimentation Control Commission and DEMLR
have created and adopted a North Carolina Erosion and Sediment Control Planning and Design Manual
describing recommended sedimentation control techniques for construction activities.
A person seeking coverage under this .permit shall take the following steps in the following order:
1. Develop an E&SC plan that adheres to the SWPPP requirements of this permit, the SPCA and 15A
NCAC 048.0101-.0132. The North Carolina Erosion and Sediment Control Planning and Design
Manual shall be used as guidance in meeting the applicable requirements.
2. Obtain approval of the E&SC plan by either DEMLR or the appropriate state delegated local
entity (hereafter known as the "E&SC plan authority").
3. Submit an electronic Notice of Intent (e-NOI) to DEMLR with documentation of the E&SC plan
approval scanned and uploaded. The e-N01 is available at https://deq.nc,gov/NCG01. In
addition, pay the general annual permit fee provided for in § 143-215.31). DEMLR shall email
the COC within three business days (or 24 business hours for a project being reviewed under
DEMLR's Express review program) after the submittal of a complete and correct e-NOI and the
receipt of the general permitting fee.
4. Commence the construction activity after receipt of the COC.
5. Abide by the conditions of both the NCG01 permit and the E&SC plan until completion of the
construction activity and establishment of permanent ground stabilization.
6. Contact the E&SC plan authority after construction is complete and the site is permanently
stabilized, contact the E&SC plan authority for the final/close out inspection of the E&SC plan.
7. Submit an electronic Notice of Termination (e-NOT) with a scan of the close-out inspection
report uploaded. The e-NOT is available at httl2s:/Ideq.nc.gov/NCG01. DEMLR shall email
confirmation of the close-out of the COC within three business days after the submittal of a
complete and correct e-NOT.
The discharges allowed by this General Permit shall not cause or contribute to violations of North
Carolina Water Quality Standards for surface waters and wetlands (1SA NCAC 026.0200). Discharges
allowed by this permit must meet all applicable water quality certification or permit requirements as
outlined in 15A NCAC 02H .0500 and 02H .1300. This permit does not relieve the permittee from
responsibility for compliance with any other applicable federal, state, or local law, rule, standard,
ordinance, order, judgment, or decree. This General Permit does not cover any other point source
discharge to surface waters of the state, nor does it cover activities or discharges that are covered by an
individual NPDES permit.
Any owner or operator of a subject construction activity not wishing to be covered or limited by this

Page 5 of 26

Permit No. NCG010000
9. Lower Portions of the Site
Portions of a site that are lower in elevation than adjacent discharge locations and are not
expected to discharge during construction may be exempt from the temporary ground cover
requirements if identified on the approved E&SC plan or added by the E&SC plan authority.
SECTION C; ADDITIONAL DESIGN AND CONSTRUCTION STANDARDS IN HIGH
QUALITY WATER (HQW) ZONES
1. Extent of the HQW Zone
HQW Zones are those areas in the 20 Coastal Counties that are within 575 feet of High Quality
Waters and for the remainder of the state, areas that are within one mile of and drain to HQWs.
2. Disturbed Area Limits in HQW Zones
Disturbed areas in HQW zones shall be limited at any time to a maximum total area within the
boundaries of the tract of 20 acres. Only the portion of the construction activity within a HQW zone
shall be subject to the 20-acre limit. Larger disturbed areas may be allowed with the written
approval of the Director upon providing adequate engineering justification with a specific
construction sequence that addresses phasing, limited exposure, weekly submitted self -inspection
reports and/or more conservative design than the 25-year storm. The Director may also include
other conditions as necessary based on specific site conditions.
3. Additional Sediment Basin Requirements in HQW Zones
Sediment basins that discharge to HQW Zones shall be designed and constructed to meet the
following criteria unless the permittee demonstrates to the E&SC plan authority that meeting each
of the basin design conditions below would result in design or operational hardships. Alternative
control measures, such as quicker application of ground cover or use of sediment flocculants, shall
be allowed as a substitute on a case -by -case basis if it can be shown that use of the alternate
practices is expected to result in an equal or better sediment discharge reduction from the site.
(a) Use a surface withdrawal mechanism except when the basin drainage area is less than 1.0 acre.
(b) Have a minimum of 1800 cubic feet per of storage area per acre of disturbed area.
Cc) Have a minimum surface area of 325 square feet per cfs for the peak flow from the 25-year
storm.
(d) Have a minimum dewatering time of 48 hours.
(e) Incorporate three baffles unless the basin is less than 20 feet in length, in which case two baffles
are sufficient.
4. Open Channels in HQW Zones
Newly constructed open channels in HQW zones shall be designed and constructed with side slopes
no steeper than two horizontal to one vertical if a vegetative cover is used for stabilization unless soil
conditions permit a steeper slope or where the slopes are stabilized by using mechanical devices,
structural devices or other acceptable ditch liners. The angle for side slopes shall be sufficient to
restrain accelerated erosion.

Permit No. NCG010000
SECTION D: CONSTRUCTION ACTIVITY BUFFERS
The requirements in Section D below shall not apply to a land -disturbing activity in connection with the
construction of facilities to be located on, over, or under a lake or natural watercourse (NCGS 113A-57).
1. Buffers in Non -Trout Waters
Unless wider buffers are required per NC rules or statutes, the width of the buffer shall be sufficient
to confine visible sedimentation to the 25 percent of the strip closest to the land -disturbing activity.
The width of a buffer adjacent to a non -trout water shall be measured from the edge of the water to
the nearest edge of the disturbed area.
Recommended buffer widths to achieve this standard are shown in Table 2 below.

2. Buffers in Trout Waters
Unless wider buffers are required per NC rules or statutes, the minimum width for an undisturbed
buffer adjacent to trout waters shall be 25 feet. The width of a buffer adjacent to a trout water shall
be measured horizontally from the top of bank to the nearest edge of the land -disturbing activity.
However, the Sedimentation Control Commission may approve plans that include land -disturbing
activity along trout waters when the duration of said disturbance would be temporary and the
extent of said disturbance would be minimal. (NCGS 113A-57(1)).
SECTION E: GROUND STABILIZATION
1. Ground Stabilization Timelines
Ground stabilization shall be achieved on any area of a site where land disturbing activities have
ceased within the timeframes listed in Table 3 below. It is recommended to stabilize the ground
more quickly if practicable. Extensions of time may be approved by the E&SC plan authority based
on weather or other site -specific conditions that make compliance impracticable. Portions of a site
that are lower in elevation and not expected to discharge during construction may he exempt from
the temporary ground cover requirements if identified on the E&SC plan and approved by the E&SC
plan authority.

drainage areas, or the disturbed areas draining to E&SC measures shall be approved by the
E&SC plan authority. Deviations from the approved E&SC plan, or approved revised E&SC plan,
shall constitute a violation of this permit unless the deviation is to correct an emergency
situation where sediment is being discharged off the site. The E&SC plan authority may allow
deviations from the E&SC plan on a case -by -case basis if the deviations are minor adjustments to
Page 9 of 26

Permit No. NCG010000
address minor deficiencies. A minor adjustment shall be the addition of E&SC measures (e.g.,
silt fence, inlet protection, check dams, rolled erosion control practices, etc.), or the relocation of
E&SC measures that would improve the overall stormwater management and sediment control
onsite. Minor adjustments shall be noted on the approved E&SC plan and maintained at the job
site.
2. Operation and Maintenance
The permittee shall install and maintain all temporary and permanent E&SC measures as required
by this permit and the approved E&SC plan.

modifications or additions to control measures, or corrective actions to control sediment or other
pollutants, these actions shall be performed as soon as possible considering adverse weather and
site conditions.
4. Draw Down of Sediment Basins for Maintenance or Close Out
Sediment basins and traps that receive runoff from drainage areas of one acre or more shall use
outlet structures that withdraw water from the surface when these devices need to be drawn
down for maintenance or close out unless this is infeasible. The circumstances in which it is not
feasible to withdraw water from the surface shall be rare (for example, times with extended cold
weather). Non -surface withdrawals from sediment basins shall be allowed only when all of the
following criteria have been met:
(a) The E&SC Plan authority has been provided with documentation of the non -surface withdrawal
and the specific time periods or conditions in which it will occur. The non -surface withdrawal
shall not commence until the E&SC plan authority has approved these items,
(b) The non -surface withdrawal has been reported as an anticipated bypass in accordance with Part
III, Section C, Item (2)(c) and (d) of this permit,
(c) Dewatering discharges are treated with controls to minimize discharges of pollutants from
stormwater that is removed from the sediment basin. Examples of appropriate controls include
properly sited, designed and maintained dewatering tanks, weir tanks, and filtration systems,
(d) Vegetated, upland areas of the sites or a properly designed stone pad is used to the extent
feasible at the outlet of the dewatering treatment devices described in Item(c) above,
(e) Velocity dissipation devices such as check dams, sediment traps, and riprap are provided at the
discharge points of all dewatering devices, and
{f) Sediment removed from dewatering treatment devices described in Item(c) above is disposed of
in a manner that does not cause deposition of sediment into waters of the united States.
S. Bypass of E&SC Measures
Diversions of stormwater from E&SC measures when the design storm has not been exceeded are
not allowed. Bypasses of E&SC measures shall be reported in accordance with Part III, Section C,
Item (2)(c) and (d) of this permit.

Fact Sheet on the New NCG01 Permit
April 2019 an*lcnnoua ~
owanm.m m E...o�me�ri u��
The NC Construction General Permit (also known as "NCG01") was renewed on April 1, 2019. The updated permit
does not significantly change the measures that are required to be implemented on construction sites. However,
there are some organizational and technical updates to the permit as described below. Most notably, there is a new
process in which construction sites will obtain official coverage under an NCG01 permit through an electronic
process. DEMLR worked with a broad team of stakeholders to make all of these updates. If you have questions,
contact Annette Lucas at [e-mail] or [phone].
Organizational Updates
The new permit:
• Repeats state requirements for E&SC
Plans and organizes them with federal
construction activity requirements;
• Is clearly organized by topic; and
• Has less text and more tables.
Technical Updates
The new permit:
• Requires that the E&SC Plan meet
SWPPP requirements (p. 2);
• Provides a list of items that must be
included in the SWPPP, such as the
construction sequence, plans,
calculations, etc. (p. 2-4);1
• Has updated language on bypasses and
upsets that is tailored to construction
activities (p. 10);
• Puts all timeframes for inspections,
record -keeping and reporting in
"calendar days" for clarity and
consistency (p. 11-14);2
• Changes the inspection frequency
(during business hours) to at least
once per 7 calendar days and after
every storm > 1.0 inch (previously 0.5
inch);3 and
• Excludes weekends, state and federal
holidays from normal business hours
unless construction activities take
place (p. 23).
This list is based on website guidance
by the DEMLR Sediment Program.
The number of calendar days was
selected to be as equivalent as
possible with the previous permit.
The intent is to provide predictability
to the inspection schedule.
Acronyms to Know
COC: Certificate of Coverage, proof of coverage under an NCG01 permit
DEMLR: NC Division of Energy, Mineral, and Land Resources
E&SC: Erosion & Sedimentation Control
e-NOI: Notice of Intent, application form for the NCG01 permit
e-NOT: Notice of Termination, form for closing out the NCG01 permit
SWPPP: Stormwater Pollution Prevention Plan, required by the NCG01
The NCG01 Process
The new NCG01 applies to permits approved on or after April 1, 2019.
Permittees will no longer receive a copy of the NCG01 permit in the mail
with their E&SC Plan approvals and be considered as covered under the
permit. Federal rules require that DEMLR receive an NCI on each
construction project and issue each construction project its own COC.
Under the new NCG01 process, construction sites will continue to
receive approval for E&SC Plans from either DEMLR or the delegated
local E&SC program just like before. After receiving E&SC Plan approval,
permittees will officially obtain coverage under the NCG01 by
completing an a-NOI (available at deg.ncgov/NCG01/NCG01). The e-NCI will
only take about 20 minutes to fill out and submit on-line.
Initially, there will be no charge associated with applying for an NCG01
permit but on or around June 1, 2019, DEMLR will begin charging a $100
annual general permit fee as required per §143-215.3D.
DEMLR is working on creating a single application form that will allow an
applicant to simultaneously apply for an E&SC permit and an NCG01
COC. That effort is part of a larger Permit Transformation project at
DEMLR.

Q&A About the New NCG01 Permit
Why do construction sites have to do this extra application step?
DEMLR is required by the EPA to issue a specific COC to every construction
site that disturbs one acre or more. DEMLR is working to create a form
that combines the E&SC plan approval and a-NOI processes, but that will
take more time. For now, DEMLR has created an efficient a-NOI process.
If an E&SC Plan is approved before April 1, which permit applies?
Projects with already approved E&SC Plans will automatically follow the
new NCG01 permit, but will not need to fill out an e-NOI or pay an annual
permit fee. However, the permittees should print the new permit and the
two standard detail sheets and have them on site.
Will DEMLR offer tools to help permittees comply with the new NCG01?
Yes, DEMLR will provide two sample plan sheets at deg.nc.gov/NCG01 that
can be placed into the E&SC plan set. The first covers the site stabilization
and materials handling portions of the permit. The second sheet covers
the inspection, record -keeping and reporting portions of the permit.
How will the new a-NOI submittal and COC process work?
Permittees will apply for E&SC Plan approvals from DEMLR or the local
E&SC program like before. The E&SC approval letter will instruct the
permittee to visit deg.nc.gov/NCG01 to submit an a-NOI form to DEMLR.
The permittee may begin the construction activity after receipt of the COC
(within three days*). The permittee must print and retain a copy of the
permit and the COC on site. Initially, the COC will be issued for free but on
or around June 1, 2019, a $100 annual general permit fee will be charged.
Who is allowed to submit an a-NOI form?
Submittal must be by a responsible corporate officer that owns or
operates the activity, such as a president, secretary, treasurer, or vice
president or a manager that is authorized in accordance with IV.B.6 of the
NCG01 permit. Additional signatory options are set forth in IV.13.6 of the
permit. It is possible for consultant to prepare the a-NOI, save it as a draft,
and email it to the responsible entity for signature & submittal.
What happens to the COC when the construction activity is complete?
When a project is complete, the permittees will contact DEMLR or the local
delegated program to close out the E&SC Plan. After DEMLR or the local
E&SC program inform the permittee of the project close out via inspection
report, the permittee will visit deg.nc.gov/NCG01 to submit an e-NOT.
Will there be a grace period for adherence to the new process?
DEMLR does not have the authority to grant a grace period from a
federally mandated permit. Permittees will be informed of the new
process via web site, E&SC Plan approval letters and list servs. If a
construction activity disturbs one acre or more (or is part of common plan
of development that disturbs one acre or more) fails to submit an a-NOI
after approval of its E&SC Plan, this is a violation of federal permitting
requirements and the permittee could be subject to a penalty assessment.
How does the new NCG01 affect the
delegated local E&SC Programs?
Local programs will continue to review
and approve E&SC plans. However,
they will no longer send copies of the
NCG01 with E&SC Plan approvals.
DEMLR will provide sample language to
use in local E&SC Plan approvals to
advise permittees that they must
submit an a-NOI to DEMLR.
Local programs are not required to
check if permittees have submitted e-
NOls to DEMLR. However, if they wish
to do this voluntarily, there will be a
tool available on DEMLR's web site for
them to view a list of construction
projects that have submitted a-NOIs.
When local programs close out an E&SC
Plan, the close-out letter will advise
permittees that they must submit an e-
NOT. DEMLR will provide sample
language.
Local programs may approve E&SC
plans that meet state sediment laws
and rules even if those plans are not
compliant with all of the NCG01
requirements. However, their
permittees will be required to add two
plan sheets (which will be provided by
DEMLR) to their E&SC Plans to ensure
that they fully comply with the ground
stabilization, materials handling, and
inspection, record -keeping and
reporting portion of the NCG01 permit.
