Ms. Mary Gornto, City Manager
Post Office Box 1810
Wilmington NC 28402
Dear Ms. Gornto:
This office has received a soil erosion and sedimentation control plan for the project listed below which
was submitted as required by the North Carolina Sedimentation Pollution Control Act (NCGS 1 13A-57).
Please be advised that this Act requires that all persons disturbing an area of one or more acres of land
must obtain approval of a soil erosion control plan prior to the commencement of said land disturbing activity
(NCGS 113A-54(d)(4)). The act further states that this plan must be filed a minimum of 30 days prior to the
activity and the approving authority must approve or disapprove the submitted plan within 30 days of receipt.
Failure of the approving authority to approve or disapprove the submitted plan within the 30 day period will
be deemed approval of the plan. Commencement or continuation of a land -disturbing activity under the
jurisdiction of this Act prior to the approval of an erosion and sediment control plan is a violation of the Act.
This land disturbing activity described in this plan is also subject to the Environmental Management
Commission's review of their regulations to implement stormwater controls in coastal counties (15 NCAC 2H
Section .1000). Contact the Water Quality Supervisor of the Division of Environmental Management to ensure
this activity is in conformance with their rules.
If you have questions, please do not hesitate to contact this office. Your cooperation in this matter
is appreciated and we look forward to working with you on this project.
Sincerely,
Carol N. Miller
Environmental Technician
