All applicable Virginia Erosion and Sediment Control Regulations and Minimum Standards shall be adhered to during all phases of construction. These include, but are not limited to the following. 1. STABILIZATION OF DENUDED AREAS. Permanent or temporary soil stabilization shall be applied to Kara areas within seven days after final grade is reached on any portion of the site Temporary soil stabilization shall be applied within seven dads to denuded areas that may not be at final grade, but will remain dormant or undisturbed for longer than 14 days. Permanent stabilization shall be applied at areas that are to be left dormant for more than 1 year. 2. STABILIZATION OF SOIL STOCKPILES - During construction of the project, :soil stockpiles shall be stabilized or protected with sediment trapping measures. The applicant is responsible for temporary protection and permanent stabilization of all soil stockpiles on site as well as soil intentionally transported from the project site. 3.PERMANENT VEGETATIVE COVER A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieve that, in the ©pinion of the county Inspector, is uniform and meatus enough to surviva to inhibit erosion. 4.TIMING & STABILIZATION OF SILT TRAPPING MEASURES - Sediment basins and traps, parimeter dikes, sediment barriers and rather measures intended to trap sedirraent shall be constructed as ca first step in any land disturbing activity and shall be made functional before upslope land disturbance takes place. 5. STABILIZATION OF EARTHEN STRUCTURES - Stabilization reasures shall be applied to earthen structures such ns darns, dikes and diversions immediately after installation. 6. SEDIMENIT TRAPS AND BASINS. A sediment basin shall control surface runoff from disturbed areas that is comprised of flow frorn drainage arenas greater than or equal to three acres. The sediment basin shall be designed and constructed to accommodate the anticipated sediment loading for the land disturbing activity. The out -fall device or system devices shall take into account the total drainage area flowing through the disturbed area to be served by the basin, 7.CUT AND FILL SLOPES: Gnat and fill slopes shall be designed and constructed in a manner that will rninirnize erosion, Slopes that are found to be eroding excessively within one year of permanent stabilization shall be provided vd0i additional slope stabilizing MOGSures until the problem is corrected. o CONCOENTRATED RUN-OFF DOWN( CUT OR FILL SLOPES. Concentrated runoff shall not flow down cut or fill .slopes unless contained within an adequate temporary or permanent channel, flume, or slope drain structure. 9.WATER SEEPS FROM A SLOPE FACE - Whenever water seeps from a slope face, adequata drainage or other protection shall be provided. 10. STORNNI SEWER INLET PROTECTION - All storm sevaaor inlets that are made operable during construction shall be protected so that sediment -laden water cannot enter the conveyance system without first haing fi➢tared or otherwise treated to rernove sediment. 11. STABILIZATION OF 01UTLETS; Before newly constructed stormwater conveyance channels are made operational, adequate outlet protection and any required temporary or permanent channel lining shall be installed in both the conveyance channel and receiving channel., 12. WCOIRK IN LIVE WATERCOURSES - When work in a live watercourse is performed, precautions shall be taken to minimize encroachment, control sediment transport and stabilize the work area to the greatest extent possible during construction. Nonerodible material shall be used for the construction of causeways and cofferdams. Earthen fill may be used for these structures if armored by nonerod'able cover materials. 13, CIROSSINiG A LIVE WATERCOURSE, When a live watercourse must be crossed by construction vehicles more than twice in any six month period, a temporary stream crossing constructed of nonerodible materials shall be provided. 14.

Effluont for de -watering operations shall be filtered or passed through approved sediment trapping device, or bath, and discharged in a manner that does not adversely affect floaasing streams or offsite property, d,Mlateriaal used for baackfilling trenches shall be properly compacted in order to minimize erosion and promote stabilization, e.Restabilization shall be accomplished in accordance with those regulations, f, Applicable safety regulations shall be complied with. 17. CCONSTRUCTIONI ACCESS ROUTES - Where construction vehicle access routes intersect paved public roads, provisions shall be made to minimize the transport of sediment by vehicular trucking onto proved surfaces, Where sediment is transported on to a public road surface, the road shall be cleaned thoroughly at the and of each day. Sediment shall be removed by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This provision shall apply to individaaal leas as well as to larger land disturbing activities. 18. TEMPORARY E S CONTROL MEASURE REMOVAL - All terraporary erosion and sediment control reasures shall be removed within :30 days after final site stabilization or after temporary measures are no longer needed, unless otherwise authorized by than local program authority. Trapped sediment and the disturbed snail areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sediment, 19.ADEQUACY OF RECEIVING CHANNELS: Properties and waterways downstrecim from the development site shall be protected from sediment deposition, erosion and damage, due to increases in volume, velocity and peak flow ratan of stormwator runoff for the stated frequency storm of 24-hour duration.
