Unless otherwise noted, the definitions set forth in Iowa
Code section
455B301.
and 567-Chapter 100, which are incorporated by reference; the definitions that
appear in specific rules within this chapter; and the following definitions
shall apply to this chapter: [See Objection
at end of chapter]
"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 113.12(455B).
"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 113.12(45 5B).
"Aquifer" has the same meaning as in
567-Chapter 100.
"Commercial solid waste " means all types of
solid waste generated by stores, offices, restaurants, warehouses, and other
nonmanufacturing activities, excluding residential and industrial
wastes.
"Existing MSWLF unit" means any municipal
solid waste landfill unit that has received solid waste as of the most recent
permit renewal.
"Facility " means all contiguous land and
structures, other appurtenances, and improvements on the land used for the
disposal of solid waste. The facility is formally defined in the permit issued
by the department. Buffer lands around a facility are not required to be
included in the permitted boundary of a facility.
"High water table" has the same meaning as
in 567-Chapter 100.
"Household waste" means any solid waste
(including garbage, trash, and sanitary waste in septic tanks) derived from
households (including single and multiple residences, hotels and motels,
bunkhouses, ranger stations, crew quarters, campgrounds, picnic grounds, and
day-use recreation areas).
"Industrial solid waste " means solid waste
generated by manufacturing or industrial processes that is not a hazardous
waste regulated under Subtitle C of RCRA. Such waste may include, but is not
limited to, waste resulting from the following manufacturing processes:
electric power generation; fertilizer and agricultural chemicals; food and
related products and by-products; inorganic chemicals; iron and steel
manufacturing; leather and leather products; nonferrous metals manufacturing
and foundries; organic chemicals; plastics and resins manufacturing; pulp and
paper industry; rubber and miscellaneous plastic products; stone, glass, clay,
and concrete products; textile manufacturing; transportation equipment; and
water treatment. "Industrial solid waste" does not include mining waste or oil
and gas waste.
"Lateral expansion " means a horizontal
expansion of the waste boundaries of an existing MSWLF unit.
"Municipal solid waste landfill (MSWLF)
unit" means a discrete area of land or an excavation that receives
household waste, and that is not a land application site, surface impoundment,
injection well, or waste pile, as those terms are defined under 40 CFR Part
257.2. An MSWLF unit also may receive other types of RCRA Subtitle D wastes,
such as commercial solid waste, nonhazardous sludge, construction and
demolition debris, and industrial solid waste. An MSWLF unit may be publicly or
privately owned. An MSWLF unit may be a new MSWLF unit, an existing MSWLF unit,
or a lateral expansion. A construction and demolition landfill that receives
residential lead-based paint waste and does not receive any other household
waste is not an MSWLF unit.
"New MSWLF unit" means any municipal solid
waste landfill unit that has not received waste prior to the most recent permit
renewal.
"Open burning" has the same meaning as in
567-Chapter 100.
"Operator" has the same meaning as in
567-Chapter 100.
"Owner " means the person(s) who owns a
facility or part of a facility.
"Point of compliance"
or"POC" means the point at which the MSWLF owner or operator
demonstrates compliance with the liner performance standard, if applicable, and
with the groundwater protection standard. The point of compliance is a vertical
surface located hydraulically downgradient of the waste management area that
extends down into the uppermost aquifer underlying the regulated MSWLF unit(s)
and where groundwater monitoring shall be conducted.
"Residential lead-based paint waste " means
waste containing lead-based paint that is generated as a result of activities
such as abatement, rehabilitation, renovation and remodeling in homes and other
residences. "Residential lead-based paint waste" includes, but is not limited
to, lead-based paint debris, chips, dust, and sludges.
"Runoff" means any rainwater, leachate, or
other liquid that drains over land from any part of a facility.
"Run-on " means any rainwater, leachate, or
other liquid that drains over land onto any part of a facility.
"Saturated zone " means that part of the
earth's crust in which all voids are filled with water.
"Sewage sludge" has the same meaning as in
567-Chapter 67.
"Sludge " means any solid, semisolid, or
liquid waste generated from a commercial or industrial wastewater treatment
plant, water supply treatment plant, or air pollution control facility, or any
other such waste having similar characteristics and effects exclusive of the
treated effluent from a wastewater treatment plant.
"Statistically significant increase "
or"SSI" means a statistical difference large enough to account
for data variability and not thought to be due to chance alone.
"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.
"Vertical expansion" means additional waste
placement on top of or against the side slopes of a previously filled MSWLF
unit, whether active, closed, or inactive.
"Waste management unit boundary" means a
vertical surface located at the hydraulically downgradient limit of the unit.
This vertical surface extends down into the uppermost aquifer.
