submission. Additional detailed guidelines for plan preparation may be obtained from the Administrator upon request. C. Control Objectives: An erosion and sedimentation control plan may be disapproved if the plan fails to adequately address the following control objectives: 1. Identify Critical Areas: On-site areas which are subject to severe erosion, and off- site areas which are especially vulnerable to damage from erosion and/or sedimentation, are to be identified and receive special attention. 2. Limit Time of Exposure: All land-disturbing activity is to be planned and phased to limit exposure to the stabilization timeframes established in Section 12.3.3.E. The construction sequence shall explain the phasing in detail. 3. Limit Exposed Areas: All land-disturbing activity is to be planned and conducted to minimize the size of the area to be exposed at any one time. 4. Mass Land Disturbing: In order to help maintain remaining town topography, trees, buffers, and to limit exposed areas that are open at once, mass land disturbing will not be allowed except in conformance with an approved plan. For development over 20 acres in land disturbance area, phased grading must be shown on the plans to limit the potential for soil erosion and off-site sedimentation. Single Family Residential Developments shall not grade more than 20 acres per phase at one time. Each phase of the development must be stabilized with adequate ground cover sufficient to restrain erosion and all infrastructure installed prior to grading an additional phase of development. Exceptions to this requirement may be granted by the Town if compliance is not practicable due to physical site constraints, such as topography, presence of stream buffers or other natural features, or lot dimensions; or due to presence of existing development or infrastructure. 5. Control Surface Water: Surface water runoff originating upgrade of exposed areas should be controlled to reduce erosion and sediment loss during the period of exposure via sediment control basins in accordance with NC Sediment and Erosion Control Planning and Design Manual. 6. Control Sedimentation: All land-disturbing activity is to be planned and conducted to prevent off-site sedimentation damage. 7. Manage Stormwater Runoff: Plans are to include measures to control the velocity at the point of discharge to minimize accelerated erosion and increased sedimentation of the site and stream. Such measures shall be in accordance with this section, the NC Stormwater Design Manual, and the National Pollutant Discharge Elimination System. D. Grounds for Disapproval: An erosion control plan may be disapproved upon finding that an applicant, or any parent or subsidiary corporation (if the applicant is a corporation): 1. Has not submitted a complete application, including the Land Disturbance checklist. 2. Is conducting or has conducted land-disturbing activity without an approved plan or has received a notice of violation on a plan previously approved and has not complied with the notice within the time specified in the notice. 3. Has failed to pay a civil penalty assessed pursuant to the North Carolina Sedimentation Pollution Control Act or a local ordinance adopted pursuant to the Act which is due and for which no appeal is pending. 4. Has been convicted of a misdemeanor pursuant to a NCGS §113A- 64(b) or any criminal provision of a local ordinance adopted pursuant to the North Carolina
