The Soil Erosion and Sedimentation Control Plan (S&E) you submitted has been reviewed and
accepted. The Town of Apex (Town) hereby issues this Letter of Plan Approval. The Town's S&E
program is performance oriented, requiring protection of the natural resources and adjoining
properties. If at any time during this project it is determined by Town staff that the approved
S&E Plan is inadequate to meet the Town's S&E ordinance, this office may require revisions to
the S&E Plan and its implementation to ensure compliance with the S&E ordinance (Section 5-
154).
In accordance with Section 5-158 of the Town's S&E ordinance, you are hereby notified that
this office has the right to periodically inspect any land -disturbing activities to ensure
compliance with the approved S&E Plan and ordinance. You are to notify this office twenty-
four (24) hours before starting work. You are also required to keep the working drawings on
site.
Stormwater runoff generated from sites disturbing one (1) acre or more is permitted pursuant
to the National Pollution Discharge Elimination System (NPDES) administered in North Carolina
by the Division of Energy, Mineral and Land Resources; Stormwater Section. 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 deg.nc.gov/NCG01. 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.
Initially, DEMLR will not charge a fee for coverage under the NCG01 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.
Complete a Grading Permit Application and receive a Grading Permit from the Building
Inspections & Permitting Department as required by the North Carolina Building Code
Appendix J for Grading. Both the Grading Permit and Certificate of Coverage from NCDEMLR
must be submitted to the Environmental Field Services Supervisor prior to the
commencement of any land disturbance activity.
The Contractor will be permitted to clear only as necessary to install the required S&E
measures. Once the required S&E measures are installed, contact Environmental Engineering
staff to schedule an on -site inspection. A Certificate of Compliance will be issued after a site
inspection is completed to ensure that the S&E measures are installed per the approved S&E
Plan.
The approval of an S&E Plan is conditioned on the applicant's compliance with Federal and
State water quality laws, regulations, and rules. In addition, the Town's NPDES Phase II permit
requires site contractors to control construction site wastes that may cause adverse water
quality impacts. Please have your site contractor review the attached Town Construction Site
Waste Management Plan to become familiar with the requirements. Town staff will inspect
your site to ensure these waste management practices are being implemented. You will need
to provide evidence of compliance if applicable.
I look forward to working with you on this project and if you have any questions, please call
[phone].
