Pollution Control Act (G S 113A-57 (4)) The 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 the land -disturbing activity (G S 113A-54(d) (4)) The review period for an express review is three days of receipt of a complete plan If additional information is requested, it must be submitted within five working days of receipt Commencement or continuation of a land -disturbing activity under the }unsdiction of this Act prior to the approval of an erosion and sediment control plan is a violation of the Act We have performed a preliminary review of your submitted plan and have determined that additional information will be necessary before a final review can be completed Enclosed is a checklist of items that must be submitted before we can complete the review, process Failure to provide the additional information may result in disapproval of your plan 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

copy of the most current deed 2 As per our meeting on 8/28/06, please indicate on the plan that roads, drainage easements and ponds must be stabilized with ground cover prior to grading lots prior to lot development If this proves impractical the amount sediment storage will need to be increased to include the amount of disturbed area associated with lot development 3 The proposed roads intersect existing ditches in at least three places on the site Please indicate whether or not the ditches are to be filled (partially or entirely — if the latter please include in the disturbed area) Additional measures other than silt fence will be necessary as silt fence is not an acceptable measure in areas of concentrated flow 4 Additional silt fence and/of undisturbed buffers are needed
