NOTICE OF RECEIPT OF EROSION & SEDIMENTATION CONTROL PLAN
Carteret Community College
Mr. Alvin T. Rhue,
3505 Arendeli Street
Morehead City NC 28557-2894
Dear Mr. Rhue:
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 113A-57(4)1.
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 11 3A-
54(d)(4)1. 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.
A copy of any erosion and sediment control plan which could involve the utilization of ditches for the purpose
of dewatering or lowering the water table is forwarded by this office to the Division of Water Quality (DWQ). It is
suggested that you contact the Division of Water Quality at [phone] if the ditches shown on your plan will
lower the water table.
The approval of an erosion and sediment control plan is conditioned on the applicant's compliance with Federal
and State water quality laws, regulations and 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.
