North Carolina Administrative Code › Title 15A - Environmental Quality › Chapter 02 - Environmental Management › Subchapter B - SURFACE WATER AND WETLAND STANDARDS › Section .0200 - CLASSIFICATIONS AND WATER QUALITY STANDARDS APPLICABLE TO SURFACE WATERS AND WETLANDS OF NORTH CAROLINA › Section 02B .0263 - JORDAN WATER SUPPLY NUTRIENT STRATEGY: DEFINITIONS

Current through Register Vol. 39, No. 2, July 15, 2024
The following words and phrases, which are not defined in
					 G.S. 143, Article 21, shall be interpreted as follows for the purposes of the
					 Jordan nutrient strategy:
(1)
				  "Allocation" means the mass quantity of nitrogen or phosphorus that a
				  discharger, group of dischargers, nonpoint source, or collection of nonpoint
				  sources is assigned as part of a TMDL. For point sources, possession of
				  allocation does not authorize the discharge of nutrients but is prerequisite to
				  such authorization through a NPDES permit.
(2) "Applicator" means the same as defined in
				  15A NCAC
				  02B .0202(4).
(3) "Channel" means a natural water-carrying
				  trough cut vertically into low areas of the land surface by erosive action of
				  concentrated flowing water or a ditch or canal excavated for the flow of
				  water.
(4) "DBH" means diameter at
				  breast height of a tree measured at 4.5 feet above ground surface
				  level.
(5) "Delivered," as in
				  delivered allocation, load, or limit, means the allocation, load, or limit that
				  is measured or predicted at Jordan Reservoir. A delivered value is equivalent
				  to a discharge value multiplied by the transport factor for that discharge
				  location.
(6) "Development" means
				  the same as defined in
				  15A NCAC
				  02B .0202(23).
(7) "Discharge," as in discharge allocation,
				  load, or limit means the allocation, load, or limit that is measured at the
				  point of discharge into surface waters in the Jordan watershed. A discharge
				  value is equivalent to a delivered value divided by the transport factor for
				  that discharge location.
(8) "Ditch
				  or canal" means a man-made channel other than a modified natural stream
				  constructed for drainage purposes that is typically dug through inter-stream
				  divide areas. A ditch or canal may have flows that are perennial, intermittent,
				  or ephemeral and may exhibit hydrological and biological characteristics
				  similar to perennial or intermittent streams.
(9) "Ephemeral stream" means a feature that
				  carries only stormwater in direct response to precipitation with water flowing
				  only during and shortly after large precipitation events. An ephemeral stream
				  may or may not have a well-defined channel, the aquatic bed is always above the
				  water table, and stormwater runoff is the primary source of water. An ephemeral
				  stream typically lacks the biological, hydrological, and physical
				  characteristics commonly associated with the continuous or intermittent
				  conveyance of water.
(10) "Existing
				  development" means development, other than that associated with agricultural or
				  forest management activities, that meets one of the following criteria:
(a) It either is built or has established a
				  vested right based on statutory or common law as interpreted by the courts, for
				  projects that do not require a state permit, as of the effective date of either
				  local new development stormwater programs implemented under
				  15A NCAC
				  02B .0265 or, for projects requiring a state
				  permit, as of the applicable compliance date established in
				  15A NCAC
				  02B .0271(5) and (6);
				  or
(b) It occurs after the
				  compliance date set out in Sub-Item (4)(d) of Rule .0265 but does not result in
				  a net increase in built-upon area.
