The City of Tega Cay is a regulated Small Municipal Separate Storm Sewer System (SMS4) and is authorized by the State to issue land disturbance and storm water permits.

Small projects require the submittal of a permit application along with a plot plan with the limits of grading shown.   Once the submittals are approved and permit fees are paid, a Land Disturbance Permit will be issued.   Standard erosion control measures (single or double-row silt fences) are required on all slopes, and other measures are required on an individual case basis.

Large projects (Including the construction of new homes) require the submittal of the above documents along with the appropriate Notice of Intent (NOI) form.  There are three types of NOI forms –

1)   Basic NOI – this is a Notice of Intent requesting coverage for the primary permittee under South Carolina’s Construction General Permit (CGP).   Along with this form, a Storm Water Pollution Prevention Plan (SWPPP) is also required.  See the Stormwater Control Plan Checklist.

2)  IL-NOI – this is an Individual Lot – Notice of Intent requesting coverage for a secondary permittee in a subdivision where the developer is the primary permittee.  In this case the developer has a SWPPP.

3)  NOI (< 1 acre) – this is for requesting coverage for a primary permittee where the proposed disturbance is less than one acre in area.

Best management practices to mitigate surface water runoff and documented weekly inspections by a certified inspector are required in all cases during construction.  See the Weekly Inspection Form.

After the large project is completed and the disturbed area is properly stabilized, the permittee must submit a Notice of Termination (NOT) to the City to close the NPDES coverage under the Construction General Permit. 

The current version of all these forms are available on the South Carolina Department of Health and Environmental Control (SCDHEC) website.   The website also offers guidance on how to complete the forms.
