We find the plan to be acceptable and hereby issue this Letter of Approval. The enclosed Certificate of Approval must be posted at the job site. This plan approval shall expire three (3) years following the date of approval, if no land-disturbing activity has been undertaken, as is required by Title 15A NCAC 4B .0129. Title 15A NCAC 4B .0118(a) requires that a copy of the approved erosion control plan be on file at the job site. 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 perforrpance-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 shall expire three (3) years following the date of approval, if no land disturbing activity has been undertaken, as required by Title 15A NCAC 4B.0029. 2. The developer is responsible for the control of sediment on site. If the approved erosion & erosion control measures prove to be insufficient, the developer must take those additional steps necessary to stop sediment from leaving this site. Each sediment storage device must be inspected after each storm event. Maintenance and/or clean out is necessary anytime the device is at 50% capacity. The amount of disturbance associated with this project is not to exceed 1.2 acres. If the amount of disturbed area needs to be increased, a revised plan reflecting all proposed site improvements must be submitted prior to starting any addition grading.
