North Carolina Administrative Code › Title 15A - Environmental Quality › Chapter 13 - SOLID WASTE MANAGEMENT › Subchapter B - SOLID WASTE MANAGEMENT › Section .0500 - DISPOSAL SITES › Section 13B .0532 - DEFINITIONS FOR C&DLF FACILITIES

Current through Register Vol. 39, No. 2, July 15, 2024
The definitions in Article 9 of Chapter 130A of the General
					 Statutes, the definitions in Rule .0101 of this Subchapter, and the following
					 definitions shall apply to Rules .0531 through .0546 of this Section.
(1) "Active life" means the period of
				  operation beginning with the initial receipt of C&D solid waste and ending
				  at completion of closure activities in accordance with Rule .0543 of this
				  Section.
(2) "Active portion" means
				  that part of a facility or unit(s) that has received or is receiving wastes and
				  that has not been closed in accordance with Rule .0543 of this
				  Section.
(3) "Aquifer" means a
				  geological formation, group of formations, or portion of a formation capable of
				  yielding groundwater.
(4) "Areas
				  susceptible to mass movement" means those areas characterized as having an
				  active or substantial possibility of mass movement where the movement of earth
				  material at, beneath, or adjacent to the C&DLF unit(s), because of natural
				  or man-induced events, results in the downslope transport of soil and rock
				  material by means of gravitational influence. Areas of mass movement may
				  include landslides, avalanches, debris slides and flows, soil fluction, block
				  sliding, and rock fall.
(5) "Base
				  liner system" means the liner system installed on the C&DLF unit's
				  foundation to control the flow of leachate.
(6) "Cap system" means a liner system
				  installed over the C&DLF unit(s) to minimize infiltration of precipitation
				  and contain the wastes.
(7)
				  "C&D solid waste" means solid waste generated solely from the construction,
				  remodeling, repair, or demolition operations on pavement and buildings or
				  structures. C&D solid waste may include municipal and industrial solid
				  wastes that are identical to materials generated from the construction,
				  remodeling, repair, or demolition operations on pavement and buildings or
				  structures.
(8) "Construction and
				  demolition debris landfill unit" or "C&DLF unit" means a discrete area of
				  land or an excavation that receives C&D solid waste, and is not a land
				  application unit, surface impoundment, injection well, or waste pile, as
				  defined under 40 CFR
				  257.2. Such a C&DLF unit may be publicly
				  or privately owned; and may be located at a municipal solid waste landfill
				  facility, an industrial solid waste landfill facility, or other waste
				  management facility.
(9)
				  "Groundwater" means water below the land surface in a zone of
				  saturation.
(10) "Karst terranes"
				  means areas where karst topography, with its characteristic surface and
				  subterranean features, is developed as the result of dissolution of limestone,
				  dolomite, or other soluble rock. Characteristic physiographic features present
				  in karst terranes may include sinkholes, sinking streams, caves, large springs,
				  and blind valleys.
(11) "Landfill
				  facility" means all contiguous land and structures, waste management unit(s),
				  other appurtenances, and improvements on the land within the legal description
				  of the site included in or proposed for the permit issued in accordance with
				  this Subchapter.
(12) "Landfill
				  unit" means a discrete area of land or an excavation that receives a particular
				  type of waste such as C&D, industrial, or municipal solid waste, and is not
				  a land application unit, surface impoundment, injection well, or waste pile, as
				  defined under 40 CFR Part 257.2. Such a landfill unit may be publicly or
				  privately owned, and may be located at a municipal solid waste landfill
				  facility, a construction and demolition debris landfill facility, an industrial
				  solid waste landfill facility, or other waste management facility.
(13) "Lateral expansion" means a horizontal
				  expansion of the waste boundaries of a C&DLF unit(s).
(14) "Liner system" means an engineered
				  environmental control system which can incorporate filters, drainage layers,
				  compacted soil liners, geomembrane liners, piping systems, and connected
				  structures.
(15) "Liquid waste"
				  means any waste material that is determined to contain "free liquids" as
				  defined by EPA SW-846 Test Method 9095B (Paint Filter Liquids Test), which is
				  incorporated by reference including subsequent amendments or editions; and can
				  be obtained free of charge at the US EPA website at
www.epa.gov/hw-sw846/sw-846-test-method-9095b-paint-filter-liquids-test
.
(16) "Poor foundation conditions" means those
				  areas where features exist that indicate that a natural or man-induced event
				  may result in a loss or reduction of foundation support for the structural
				  components of a C&DLF unit(s).
(17) "Project engineer" means the licensed
				  professional engineer that represents the permittee and is responsible for
				  observing, documenting, and certifying that activities related to the quality
				  assurance of the construction of the solid waste management unit conform to the
				  permit to construct, incorporated plans, and Rules .0531 through .0546 of this
				  Section. All certifications shall bear the seal and signature of the licensed
				  professional engineer and the date of certification.
(18) "Seasonal high groundwater table" and
				  "SHGT" means the highest level of the uppermost aquifer during a year with
				  normal rainfall. SHGT may be determined in the field through identification of
				  redoximorphic features in the soil profile, monitoring of the water table
				  elevation, or modeling of predicted groundwater elevations.
(19) "Structural components" means liners,
				  leachate collection systems, final covers, systems that manage rainwater that
				  drains over land from or onto any part of the facility or unit and any other
				  component used in the construction and operation of the C&DLF
				  facility.
(20) "Unstable area"
				  means a location that is susceptible to natural or human-induced events or
				  forces capable of impairing the integrity of some or all of the landfill
				  structural components responsible for preventing releases from a landfill.
				  Unstable areas may include poor foundation conditions, areas susceptible to
				  mass movements, and Karst terranes.
(21) "Uppermost aquifer" means the geologic
				  formation nearest the natural ground surface that is an aquifer, as well as
				  lower aquifers that are hydraulically interconnected with this aquifer within
				  the facility's property boundary.
