If contiguous lots are graded such that one acre or more is disturbed, individual lot controls
will be insufficient, and surface dewatering is required in order to maintain compliance with
the NPDES general construction permit. This site is limited to individual lot disturbance. If
contiguous lot grading for lots totaling I acre or more is to take place, an approved plan is
required before grading takes place, with specific Locations for surface dewatering,
specifications and calculations for surface dewatering. [N.C.G.S. 143-215.11
Any off -site borrow and waste required for this project must come from a site with an
approved erosion control plan, a site regulated under the Mining Act of 1971, or a landfill
regulated by the Division of Solid Waste Management. Trash/debris from demolition

the Division of Solid Waste Management or per Division of Solid Waste Management or
Division of Water Resources rules and regulations. [ 15A NCAC 4B .0110]
