North Carolina Administrative Code › Title 15A - Environmental Quality › Chapter 13 - SOLID WASTE MANAGEMENT › Subchapter B - SOLID WASTE MANAGEMENT › Section .1600 - REQUIREMENTS FOR MUNICIPAL SOLID WASTE LANDFILL FACILITIES (MSWLFS) › Section 13B .1602 - DEFINITIONS

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 the rules of this Section.
(1) "Active life" means the period of
				  operation beginning with the initial receipt of solid waste and ending at
				  completion of closure activities in accordance with Rule .1627 of this
				  Section.
(2) "Active portion" means
				  that part of a facility or unit that has received or is receiving wastes and
				  that has not been closed in accordance with Rule .1627 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 MSWLF 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 MSWLF unit's foundation
				  to control the flow of leachate.
(6) "Cap system" means a liner system
				  installed over the MSWLF unit to minimize infiltration of precipitation and
				  contain the wastes.
(7) "Gas
				  condensate" means the liquid generated as a result of gas recovery processes at
				  a MSWLF unit.
(8) "Groundwater"
				  means water below the land surface in a zone of saturation.
(9) "Household waste" means any solid waste
				  derived from households including single and multiple residences, hotels and
				  motels, bunkhouses, ranger stations, crew quarters, campgrounds, picnic
				  grounds, and day-use recreation areas.
(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
				  Section.
(12) "Landfill unit" means
				  a discrete area of land or an excavation that receives a particular type of
				  waste such as construction and demolition, industrial, or municipal 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 landfill may be publicly or
				  privately owned, and may be located at a municipal solid waste landfill
				  facility, a construction and demolition solid waste landfill facility, an
				  industrial solid waste landfill facility, or other waste management
				  facility.
(13) "Liner system" means
				  an engineered environmental control system which can incorporate filters,
				  drainage layers, compacted soil liners, geomembrane liners, piping systems, and
				  connected structures.
(14) "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
.
(15) "Municipal solid waste landfill unit" or
				  "MSWLF unit" means a discrete area of land or an excavation that receives
				  household waste, and is not a land application unit, surface impoundment,
				  injection well, or waste pile, as defined under
				  40 CFR
				  257.2. Such a landfill may be publicly or
				  privately owned. A MSWLF unit may also be permitted to receive other types of
				  non-hazardous solid waste.
(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 MSWLF
				  unit(s).
(17) "Project engineer"
				  means a 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
				  facility conform to the permit to construct, incorporated plans, and the rules
				  of this Section. All certifications shall bear the seal and signature of a
				  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 MSWLF
				  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.
