<br />topography, existing soil cover (both vegetative and non - vegetative), or the existing soil
<br />topography that may result in accelerated stormwater runoff, le ding to soil erosion and
<br />movement of sediment into surface waters or drainage systems. Examples of construction
<br />activity may include clearing, grading, filling, and excavating. Construction activity
<br />includes the disturbance of less than one acre of total land area that is a part of a larger
<br />common plan of development or sale if the larger common plan will ultimately disturb
<br />one acre or more.
<br />EROSION PREVENTION - means measures employed to prevent erosion including,
<br />but not limited to, soil stabilization practices, limited grading, mulch, temporary or
<br />permanent cover, and construction phasing.
<br />FILTRATION - A stormwater quality BMP that uses either natural media such as
<br />soil or vegetation or manufactured media to trap pollutants such as nutrients and particles
<br />in surface water.
<br />FINAL STABILIZATION - means that all soil disturbing activities at the site have been
<br />completed and all soils have be stabilized by a uniform perennial vegetative cover with a density
<br />of 70% over the entire pervious surface area, or other equivalent means necessary to prevent soil
<br />failure under erosive conditions.
<br />LAND DISTURBING ACTIVITY - any disturbance to the ground surface that,
<br />through the action of wind or water, may result in soil erosion or the movement of
<br />sediment into waters, wetlands or storm sewers or onto adjacent property. Land -
<br />disturbing activity includes but is not limited to the demolition of a structure or surface,
<br />soil stripping, clearing, grubbing, grading, excavating, filling and the storage of soil or
<br />earth materials. The term does not include normal farming practices as part of an ongoing
<br />farming operation.
<br />IMPERVIOUS SURFACE - means a constructed hard surface that either prevents or
<br />retards the entry of water into the soil and causes water to run off the surface in greater
<br />quantities and at an increased rate of flow than prior to development. Examples include
<br />rooftops, sidewalks, patios, driveways, parking lots, storage areas, and concrete, asphalt,
<br />or gravel roads.
<br />NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) -
<br />means the program for issuing, modifying, revoking, reissuing, terminating, monitoring,
<br />and enforcing permits under the Clean Water Act (Sections 301, 318, 402, and 405) and
<br />United States Code of Federal Regulations Title 33, Sections 1317, 1328, 1342, and
<br />1345.
<br />OWNER - means the person or party possessing the title of the land on which the
<br />construction activities will occur; or if the construction activity is for a lease, easement,
<br />or mineral rights license holder, the party or individual identified as the lease, easement,
<br />or mineral rights license holder; or the contracting government agency responsible for the
<br />construction activity.
