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.

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. The eNOI form may be accessed at deq.nc.gov/NCG01. Please direct questions about the eNOI form 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.

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 30 days. 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, it is determined that 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 ensure 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 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 starting date for this project. Your cooperation is appreciated. Sincerely, DocuSi9ned by: e tVVOW 70735F9D3B774C3...

Sheet C-3.1: Sediment Basin C inset callouts do not match the calculations provided. While the calculations suggest a disturbed acreage of 12.18 acres, the inset callouts show 9.12 acres. The Basin meets the required volume and surface area. However, the concern is around the proposed skimmer and orifice sizing. Ensure the skimmer is appropriately designed for each phase of construction and can drawdown the required volume within the 2-5-day requirement. If skimmers are to be changed between phases, note it on the plans and in the sequence. Provide calculations for the sediment basin for each phase of construction. 2. Sheet C-3.3: Skimmer Basin E Calculations need to be revised. Disturbed Area cannot be greater than the total drainage area. Skimmer Sizing does not match calculations. Like Modification#1, Basin E drainage and disturbed areas change in every phase of construction. Provide calculations for each phase of construction and provide callouts for changes in skimmers or basin sizing. Check skimmer sizing for Basin A—Callout shows 2.3inches, Calculations show 2.8inches. 3. Sheet C-3.5: Several Proposed Pipes travel through an existing Sanitary Sewer Easement. Prior to construction,provide documentation that the Utility Company is aware of the construction/altering of that easement and that vertical separation between the pipes is allowable. 4. Sheet C3.9-11: Provide calculations for ditch stability along Stallings Road. 5. Check Storm Sewer Profiles for all proposed pipes. Several proposed pipes have an HGL/EGL above the crown of the pipe for the 10-year storm. This typically indicates a pressure flow condition. Check local and or State regulations on design criteria. 6. Provide copies of any wetland determinations or Water Quality Certifications (401/404) for this project from the Army Corps and/or Water Quality Regional Operations Section, as well as any local approvals for activity within the buffers. All requested information must be received and approved prior to construction. 7. Is Stallings Farm Investments, LLC also constructing the houses? If so, individual lot controls must be specified for each lot either on the plans or in tabular form. 8. No Disturbance is allowed for Drainage Area B (Sediment Basin B)until the Hazard Classification North Carolina Department of Environmental Quality I Division of Energy,Mineral,and Land Resources Mooresville Regional Office 1610 East Center Avenue,Suite 301 I Mooresville,North Carolina 28115 ...... . .».�.r a.n� 704-663-1699 Docusign Envelope ID: 1EBBA277-7B86-4741-9067-4D1E2572E1A4 Letter of Approval with Modifications Stallings Farm Investments, LLC August 19, 2024 Page 4 of 4 for the proposed Dam is completed and an EAP is accepted by NCDEQ. 9.
