Erosion and Sediment Control within the Jurisdictions of Johnston County

Authority

Johnston County has been delegated the authority to implement the requirements of the State’s Sedimentation Pollution Control Act of 1973 in the unincorporated areas of the County.

Development that disturbs one (1) acre or more, or less than one (1) acre but part of a common plan of development, must have an approved erosion control plan through the County prior to beginning land disturbing activities.

  

Summary and Guidance 

Johnston County has delegated authority from the North Carolina Sedimentation Control Commission to enforce the Sedimentation Pollution Act of 1973, effective November 7, 2013. Our office is currently involved in monitoring commercial sites, as well as construction of residential subdivisions.

As a part of our program, any developer or builder that disturbs more than an acre, or less than an acre if part of a common plan of development, must submit for a sediment and erosion control permit with Johnston County Public Utilities prior to land-disturbing activities.

Lot level erosion control plans are required for individual lots in a subdivision.

Erosion Control Closeout Process

When all land disturbances have been completed, and the disturbed areas have been permanently stabilized, the erosion control permit is eligible for closeout.

Public Utilities reviews final plats for compliance with stormwater and water and sewer requirements.

How to Close Out the Erosion Control Permit

1. Complete the Project Closeout Request for Erosion Control form, found on Stormwater, Buffer, and Erosion Control Forms and Technical Guidance.  The completed Erosion Control Closeout form must be submitted with the closeout request.
2. Include a copy of the Johnston County Erosion Control Permit(s) being requested to close out.
3. Include a copy of the latest Self-Inspection Report for the area(s) being requested to be closed out. If self-inspection reports are not included, the permit will not be closed out.
4. The self-inspection should confirm the following items have been completed prior to requesting a permit closeout inspection. If the items below are not completed as applicable, the permit will not be closed out.
• All areas must have permanent vegetation established
• The site must be in compliance with all environmental permits
• Any lot level drainage swales must be in place and stabilized
• Any permanent drainage easements must be in place and stabilized
• Any SCM’s or other stormwater measures have been converted, stabilized and bonded.

When the County closes out the local erosion control permit, the County’s closeout documentation can be submitted to NCDEQ to close out coverage under NCG01.
