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 inspection 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 insure compliance with the approved plan. North Carolina's Sedimentation Pollution Control Act is perfonnance-oriented, requiring protection of existing natural resources and adjoining properties. If, following the commencement of this project, 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 insure 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. Please notify us if you plan to have a preconstruction conference. Your cooperation is appreciated.

Provide stockpile/staging areas, concrete washouts, and dedicated areas for demolition, construction, and other wastes. These areas are to be within the limits of disturbance and should be located at least 50 feet away from storm drain inlets, temporary diversions, channels, roadside ditches and surface water bodies. Identify the location of these areas and structures on the plan sheets. Provide adequate measures around the stockpile areas. A revised Financial Responsibility/Ownership Form and additional fee may be necessary, if the total disturbed acreage exceeds the original submittal.
