(2) All activities on the site shall be conducted in a logical sequence to <br /> minimize the area of bare soil exposed at any one time. <br /> (3) All disturbed ground left inactive for fourteen (14) or more days must <br /> have temporary or permanent stabilization year round. <br /> (4) For sites with more than ten(10) acres disturbed at one time, or if a <br /> channel originates in the disturbed area, one or more temporary or permanent <br /> sedimentation basins shall be constructed. Each sedimentation basin shall have a <br /> surface area of at least one percent of the area draining to the basin and at least <br /> three feet of depth and constructed in accordance with accepted design <br /> specifications. Sediment shall be removed to maintain a depth of three (3) feet. <br /> The basin discharge rate shall also be sufficiently low as to not cause erosion <br /> along the discharge channel or the receiving water. <br /> (5) Perimeter sediment control measures shall be placed along all down <br /> gradient perimeters of the site. If a channel or area of concentrated runoff passes <br /> through the site,perimeter sediment control measures shall be placed along the <br /> channel edges to reduce sediment reaching the channel. All down gradient <br /> perimeter sediment control measures must include a maintenance and inspection <br /> schedule. <br /> (6) Any soil or dirt storage piles containing more than ten(10) cubic yards of <br /> material should not be located within twenty five (25) feet from a roadway or <br /> drainage channel. If remaining for more than fourteen(14) days, they shall be <br /> stabilized by mulching vegetative cover, tarps or other means and enclosed with <br /> down gradient perimeter sediment controls. Piles which will be in existence for <br /> less than fourteen (14) days shall be enclosed with perimeter sediment controls. <br /> (7) Pipe outlets must have energy dissipation installed within twenty-four(24) <br /> hours of connection to waters of the state. <br /> (g) Inspections and Maintenance. The Owner shall be responsible for conducting <br /> inspections and maintenance of all erosion and sediment control BMPs on site. <br /> (1) Inspections, maintenance, and rainfall on site must be documented and <br /> readily available for review. Inspections are required as followed: <br /> a. Once every seven (7) days on exposed soil areas. <br /> b. Within twenty-four(24) hours after a one half inch or greater rain <br /> event over twenty-four(24) hours. <br /> c. Once every thirty(30) days on stabilized areas. <br /> d. As soon as runoff occurs or prior to resuming construction on <br /> frozen ground. <br /> 10 <br />
