As used in this chapter:
(a) “Biosolids” means a sewage sludge that has received an established treatment for required pathogen control and is treated or managed to reduce vector attraction to a satisfactory level and contains acceptable levels of pollutants, such that it is acceptable for use for land application, marketing or distribution in accordance with this chapter, as defined by the Virginia Biosolids Use Regulations (BUR), in VAC5-58, October 15, 1997.
(b) “Class B Biosolids” means a sludge that receives Class I or II treatment for adequate pathogen control and is treated or managed to properly reduce vector attraction and acceptable levels of pollutants (Table 8-A, BUR).
(c) “Exceptional quality biosolids” means a Class I treated sludge with approved control of vector attraction and acceptable levels of pollutants (Table 8-B, BUR).
(d) “Perennial stream” (as defined by the National Soil Survey Handbook, USDA Title 430) means a stream or reach of a stream that flows continuously throughout the year and whose surface is generally lower than the water table adjacent to the region adjoining the stream. Perennial streams are designated by a one dot soil drainage symbol (--.--) in the Loudoun County Soil Drains Coverage.
(e) “Intermittent stream” (as defined by the National Soil Survey Handbook, USDA Title 430) means a stream or reach of a stream that does not flow year-round and that flows only when it receives baseflow solely during wet periods, or when it receives ground water discharge or protracted contributions from melting snow or other erratic surface and shallow subsurface sources (see also ephemeral). Intermittent streams are designated by a three dot soil drainage symbol (__...__) in the Loudoun County Soil Drains Coverage.
