Disposal facility-The buildings, equipment and other engineered features, including disposal units and temporary holding facilities, within the disposal site which are used for the disposal of low-level radioactive waste.
Disposal site-The property, including improvements thereon, which is used for disposal of low-level radioactive waste. The term consists of the disposal units and the buffer zone.
Disposal Unit-A discrete portion of the disposal site into which waste is placed for disposal.
Disqualifying criteria-Conditions which would eliminate an area from further consideration for disposal.
Engineered barrier-A manmade structure or device that is intended to improve the disposal facility's ability to meet the performance objectives in this chapter.
Engineered cover-A manmade structure constructed over the disposal facility.
Engineered structure-A manmade state-of-the-art barrier designed to:
Enhanced containment-Additional isolation of the radioactive waste from the environment as provided by engineered structures.
Explosive material-A chemical compound, mixture or device which produces a substantial instantaneous release of gas and heat spontaneously or by contact with sparks or flame.
Fund-The Low-Level Waste Fund.
Generate-To produce low-level radioactive waste requiring disposal.
Generator-A person whose activity results in the production of low-level radioactive waste requiring disposal.
Groundwater-The part of the subsurface water that is in the zone of saturation, perennial or otherwise.
Hazardous life-The time required for radioactive materials to decay to safe levels of radioactivity, as defined by the time period for the concentration of radioactive materials within a given container or package to decay to maximum permissible concentrations as defined by Federal law or by standards to be set by the host state, whichever is more restrictive.
Hazardous wastes-Wastes as defined in section 103 of the Solid Waste Management Act (35 P. S. § 6018.103) and regulations thereunder.
Host municipality-A city, borough, incorporated town or township, excluding a county, in which the low-level waste disposal facility will be constructed, as designated by the Department under section 318 of the act (35 P. S. § 7130.318).
Inadvertent intruder-A person who might occupy the disposal site after closure and engage in normal activities, such as agriculture, dwelling construction or other pursuits in which an individual might be unknowingly exposed to radiation from the waste.
Intruder barrier-A manmade structure or sufficient depth of cover over the waste that inhibits contact with waste and helps to ensure that radiation exposures to an inadvertent intruder will meet the requirements under § 236.320 (relating to protection from inadvertent intruders) and the performance objectives in this subchapter.
Isolation-Protection of the public and the environment from inadvertent intrusion or direct release of radioactive material from the disposal site.
Leak resistance-The material properties of the disposal facility design which retard or prevent migration of water.
Long term care period-See the definition of time periods.
Low-level radioactive waste-Radioactive waste that meets one of the following criteria:
Management-The reduction, collection, consolidation, storage, processing, incineration, separation, minimization, compaction, segregation, solidification, evaporation, packaging or treatment of low-level radioactive waste.
Mixed waste-Waste that is low-level radioactive waste, as defined in this subchapter, and either contains a hazardous waste or exhibits a hazardous characteristic as contained in the Solid Waste Management Act (35 P. S. §§ 6018.101-6018.1003).
