Acres Approved: 3
Application ID: PA-001617
Permit Number: MECKL-2024-0102

River Basin:Yadkin-Pee Dee
Stream Classification:C:Aquatic Life,Secondary Contact Recreation, Fresh water
Plan Type: New Plan
Dear Town of Cornelius,
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.The Certificate of Approval must be
posted at the job site. 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 4B .0129.
As of April 1, 2019, all new construction activities are required to complete and submit an electronic Notice
of Intent (eNOI) form requesting a Certificate of Coverage (COC) under the NCG010000 Construction
General Permit.After the form is reviewed and found to be complete, you will receive a link with payment
instructions for the $120 annual permit fee.After the fee is processed,you will receive the COC via email. As
the Financially Responsible Party shown on the FRO form submitted for this project,you MUST obtain the
COC prior to commencement of any land disturbing activity.TheeNOlform may be accessed
atdeq.nc.gov/NCG01. Please direct questions about the eNOlform to the Stormwater Program staff in the
Raleigh central office. If the owner/operator of this project changes in the future, the new responsible
party must obtain a new COC.

Title 15A NCAC 4B .0118(a) and the NCG01 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 NCG01 permit and the COC, once it is received.
3. Records of inspections made during the previous 12 months.
Also, this letter gives the notice required by G.S. 113A-61.1(a) of our right of periodic inspection to ensure
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.
Please note that this approval is based in part on the accuracy of the information provided in the Financial
Responsibility/Ownership Form, which you provided. You are requested to file an amended form if there
is any change in the information included on the form. This permit allows for a land-disturbance, as called
for on the application and plan, not to exceed the approved acres. Exceeding the acreage can be a
violation of this permit and may require a revised plan and additional application fee. In addition, it would
be helpful if you notify this office of the proposed starting date for this project.
Modifications Required for Approval:
1. All necessary easements and access agreements must be obtained and be current prior to
starting work. All potentially affected property owners must be notified prior to utility
construction even though the activity is covered under an easement or occurs within a right-of-
way. Note that door hangers are not a sufficient method to notify homeowners as not every
property has residents.
2. Rather than ending the basin berm as indicated on the drawings, extend the southern berm to
the southwest until it ties in with the 808 existing contour line.
3. The emergency spillway should be located in native material to the extent possible and the
riprap should be extended to the bottom of the slope.
4. Sheet C4.01 has incorrect information in the skimmer basin table. The drainage area is
incorrect, and the surface areas are shown as cubic feet rather than square feet. Update this
sheet to include the correct information. Include maintenance requirements for all measures on
this sheet.

5. Sheet C5.01 shows a different emergency spillway elevation than shown on the other
sheets. The elevation shown on Sheet C 1.01 is assumed to be correct and must be used
throughout the construction phase of the project. Basin cannot be converted to a permanent
measure until upgradient areas have stabilized and NCDEQ inspector approves the conversion.
6. Provide updated drawings, two complete sets, to this office within 2 weeks of receiving this
letter or prior to starting work, whichever is sooner.
