This office has reviewed the subject erosion and sedimentation control plan. We find the plan to be acceptable
with modifications and hereby issue this letter of Approval with Modifications. The Modifications Required for
Approval are listed on the attached page. This plan approval shall expire three (3) years following the date of
approval, if no land -disturbing activity has been undertaken, as is required by Title 15A NCAC 413 .0129.
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/NCGOI. Please direct questions about
the NOI form to Annette Lucas at [e-mail] or Paul Clark at [e-mail]. After
you submit a complete and correct NOI Form, a COC will be emailed to you within three business days. 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 4B .0118(a) and the NCGO1 permit require that the following documentation be kept on file at

compliance with the approved plan.
North Carolina's Sedimentation Pollution Control Act is performance -oriented, requiring protection of existing
natural resources and adjoining properties. If, following the commencement of this project, the erosion and
sedimentation control plan is inadequate to meet the requirements of the Sedimentation Pollution Control Act of
1973 (North Carolina General Statute 113A-51 through 66), this office may require revisions to the plan and
implementation of the revisions to insure compliance with the Act.
Acceptance and approval of this plan is conditioned upon your compliance with Federal and State water quality
laws, regulations, and rules. In addition, local city or county ordinances or rules may also apply to this land -
disturbing activity. This approval does not supersede any other permit or approval.

Responsibility Form, which you provided. You are requested to file an amended form if there is any change in
the information included on the form. In addition, it would be helpful if you notify this office of the proposed

Modifications pursuant to applicable North Carolina General Statutes and/or Regulations:
1. North Carolina recently issued a new NCGO1 General Construction Stormwater Permit.
Please ensure the NCG01 Ground Stabilization and Materials Handling and Self -Inspection,
Recordkeeping and Reporting requirements are on your plans. The NCGO1 compliance plan
sheets for these can be found at https:/,,de(l,nc.gov/abotit/divisioils/'energy-mineral.-latid-
resources."energy-mni neral-land-pern-iit s/stormwater-perm its/construction-sw
2. Additional measures may be required - The applicant is responsible for the control of
sediment on -site. If the approved erosion and sedimentation control measures prove
insufficient, the applicant must take those additional steps necessary to stop sediment from
leaving this site. [15A NCAC 4B .0115]
Additional Comments:
1. Please be advised industrial activities may be subject to the National Pollutant Discharge
Elimination System (NPDES) Stormwater Program. A list of covered activities and detailed
information is available at the website below:
llttps:;':'deq.nc. gov/about/divisions:'energy-mineral-land-resources/energy-mineral-land-
perm i is/stonnwate r-pro gram
2. Be advised due to the potential activities proposed onsite, you will likely require additional
permitting from other NCDEQ agencies that may affect this erosion and sediment control
plan (for example permits related to demolition/asbestos removal/stream rerouting do not
replace the need for approval of an erosion and sediment control plan, if applicable). We
recommend you contact Mr. Paul Williams, Environmental Assistance Coordinator, NC
Division of Environmental Assistance and Customer Service to discuss your site. He can be
reached at [phone] or pawl..e.willia nsf' ;;n.edenr.gov. Be advised this review is for
erosion and sediment control only.

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. |fyou have questions,

SVVPPPrequirements (p.2);
" Provides alist ofitems that must be

Why doconstruction sites have tmdmthis extra application step?
DEM0isrequired bythe EPA toissue aspecific [DCtoevery construction
site that disturbs one acre ormore. DEMLRisworking tocreate aform
that combines the E&SCplan approval and e'NO|processes, but that will
take more time. For now, DEMLR has created an efficient e-NOI process.
If anE&SCPlan isapproved before April l,which permit applies?
Projects with already approved E&SCPlans will automatically follow the
new N0GD1permit, but will not need tofill out ane'NO|orpay anannual
permit fee. However, the permhteesshould print the new permit and the
two standard detail sheets and have them onsite.
Will DEVNLRoffer tools %ohelp penmitteescomply with the new NCG01?
Yes DEK8LRwill provide two sample plan sheets at that

and materials handling portions ofthe permit. The second sheet covers
the inspection, record -keeping and reporting portions ofthe permit,
How will the new e-NOlsubmittal and COC process work?
Pemnh1eeswill apply for E&SCPlan approvals from DEK1LRorthe local
E8'SCprogram like before. The EO^5Capproval letter will instruct the

The permittee may begin the construction activity after receipt of the COC
(within three days*).The pernmitteemust print and retain acopy ofthe
permit and the COC on site. Initially, the COC will be issued for free but on
uraround June 1,2U19,a$1OUannual general permit fee will becharged.

operates the activity, such asapresident, secretary, treasurer, orvice
president oramanager that isauthorized inaccordance with |V.B.6ofthe
NCG81 permit. Additional signatory options are set forth in |V.B.6ofthe
permit. |tispossible for consultant toprepare the e-NO|,save itasadraft,
and email ittothe responsible entity for signature &^submittal.
What happens to the COC when the construction activity is complete?
When aproject iscomplete, the pemnitteeswill contact DEK8LRorthe local
delegated program toclose out the E&S[Plan. After DEK4LRorthe local
E&SCprogram inform the permitLeeofthe project close out via inspection
report, the permitteewill visit tosubmit ane-NOT.
Will there beagrace period for adherence tuthe new process?
DEMURdoes not have the authority togrant agrace period from a
federally mandated permit. Perrnittees will be informed of the new

Local programs will continue toreview
and approve E&SCplans. However,
they will nolonger send copies ofthe
N[GOlwith E&SCPlan approvals.
DEW1LRwill provide sample language to
use inlocal E&5CPlan approvals to
advise permitteesthat they must
submit ane'NO|toDEK4LR.
Local programs are not required to
check ifpenMteeshave submitted e'

projects that have submitted e-NOls.
When local programs close out anE&SC
Plan, the close-out letter will advise
pennitteeythat they must submit ane'
NOT. DEMLRvvi/| provide sample
language.
Local programs may approve E&SC
plans that meet state sediment laws
and rules even ifthose plans are not
compliant with all ofthe NCGU2
requirements. However, their
pernniUresvvi|l be required toadd two
plan sheets (which will beprovided by
DEMLR)totheir E/&SCPlans toensure
that they fully comply with the ground
