(A) The intent of this regulation is to establish requirements for stormwater discharges from construction activities of one or more acre and consistent technically feasible and operationally practical standards so that the public health, existing water uses, and aquatic biota are protected.
(B) This regulation further intends, but is not limited, to:
(1) Allow development while minimizing increases in downstream flooding, erosion, and sedimentation;
(2) Reduce damage to receiving water resources and drainage systems that are caused by new development or redevelopment activities;
(3) Control storm water runoff resulting from soil disturbing activities;
(4) Assure that development site owners control the volume, characteristics and rate of stormwater runoff originating from their property so that surface water and groundwater are protected, soil erosion is controlled, and flooding potential is not increased;
(5) Preserve to the maximum extent practicable the natural drainage characteristics of the building site and minimize the need to construct, repair, and replace enclosed storm drain systems;
(6) Preserve to the maximum extent practicable natural infiltration and groundwater recharge, and maintain subsurface flow that replenishes water resources, wetlands, and wells;
(7) Assure that stormwater controls are incorporated into site planning and design at the earliest possible stage;
(8) Prevent unnecessary stripping of vegetation and loss of soil, especially adjacent to water resources and wetlands;
(9) Reduce the need for costly maintenance and repairs to roads, embankments, sewage systems, ditches, water resources, wetlands, and stormwater management practices that are the result of inadequate soil erosion, sediment and stormwater control;
(10) Reduce the long-term expense of remedial projects needed to address problems caused by inadequate stormwater, erosion and sediment control;
(11) Require the construction of stormwater management practices that serve multiple purposes including flood control, soil erosion and sediment control, and require water quality protection; and encourage such practices that promote recreation and habitat preservation; and
(12) Ensure that all stormwater management, soil erosion and sediment control practices are properly designed, constructed, and maintained.
