17.50.1802    DEFINITIONS

In this subchapter, the following definitions apply:

(1) "Absorbed dose" has the meaning specified in ARM 37.14.102.

(2) "Background radiation" means the natural radiation that is present in the environment. It includes cosmic radiation, which comes from the sun and stars; terrestrial radiation, which comes from the Earth, and radiation from naturally occurring radioactive materials.

(3) "Contaminated soil" has the meaning specified in ARM 17.50.403.

(4) "Curie" has the meaning specified in ARM 37.14.102.

(5) "Department" means the Department of Environmental Quality.

(6) "Dose" means the amount of radiation energy deposited in human tissue.

(7) "Exposure" is a measure of the amount of ionization produced in air by gamma photons or x-rays.

(8) "Filter media" means a porous material used to filter solids from fluids. This includes, but is not limited to, green anthracite, filter socks, water treatment socks, and activated charcoal.

(9) "Facility" has the meaning specified in ARM 17.50.502.

(10) "Health physicist" means a scientist or engineer that has sufficient training and experience to make sound professional judgments regarding radiation monitoring, equipment, environmental protection, health, and safety. The training and experience must pertain to naturally occurring radioactive materials and health physics concerning protecting people and the environment from potential radiation hazards. Sufficient training and experience is gained through a baccalaureate and/or post-graduate degree in the natural sciences or engineering, professional certifications, and work experience.

(11) "Landfill" has the meaning specified in ARM 17.50.502.

(12) "Leachate" has the meaning specified in ARM 17.50.502.

(13) "Leachate collection system" has the meaning specified in ARM 17.50.502.

(14) "Leachate removal system" has the meaning specified in ARM 17.50.502.

(15) "Licensed boundary" has the meaning specified in ARM 17.50.502.

(16) "Load" is a measured quantity of waste prepared for or being transported at any one time.

(17) "Method of receipt" means the name of the transporter and equipment used to deliver the waste to the TENORM waste management system.

(18) "Microroentgen" (µR) is one millionth of a roentgen.

(19) "Millirem" (mrem) means a unit of equivalent dose that is equal to one thousandth of a rem.

(20) "Milliroentgen" (mR) means a unit of measurement for radiation exposure that is one thousandth of a roentgen.

(21) "Picocuries" is a unit of radioactivity that is one trillionth of a curie.

(22) "Qualified ground water scientist" has the meaning specified in ARM 17.50.1302.

(23) "Radiation" means alpha particles, beta particles, gamma rays, x-rays, neutrons, high-speed electrons, high-speed protons, and other particles with sufficient kinetic energy to strip electrons from atoms. Radiation does not include non-ionizing radiation, such as radio or microwaves, or visible, infrared, or ultraviolet light.

(24) "Rem" or "roentgen equivalent man" is the dose unit representing the amount of energy absorbed in human tissue, the distribution of the energy, and the sensitivity of the whole body or individual organs to radiation.

(25) "Roentgen" (R) is the unit of measurement for x-radiation or gamma radiation producing one electrostatic unit of positive or negative ionic charge in one cubic centimeter of air under standard pressure or 0.000258 coulombs per kilogram of dry air.

(26) "Screening" means the examination and measurement procedures to verify that incoming waste meets the acceptance criteria for the waste management system.

(27) "Solid waste" has the meaning specified in ARM 17.50.403.

(28) "Solid waste management system" has the meaning specified in ARM 17.50.403.

(29) "Source" means the location where the TENORM waste is generated or, if aggregated, the location where the last aggregation occurs.

(30) "Spill" means the accidental or unintentional release of TENORM waste during transport or onsite at the TENORM waste management system in an area not designated for disposal.

(31) "Storage" has the meaning specified in ARM 17.50.403.

(32) "Technologically enhanced naturally occurring radioactive material" (TENORM) means naturally occurring radioactive material whose radionuclide concentrations are increased by or as a result of past or present human practices. TENORM does not include background radiation or the natural radioactivity of rocks and soils. TENORM does not include "source material" and "byproduct material," as both are defined in 42 USC § 2014, a section of the Atomic Energy Act of 1954.

(33) "TENORM surface-contaminated objects" means objects that have TENORM distributed on either the external or internal surfaces, or both, including but not limited to pipes, valve stems, and equipment or survey instruments.

(34) "TENORM waste" is solid waste that contains TENORM.

(35) "TENORM waste management system" means a system that accepts, stores, treats, recycles, recovers, disposes, or transports TENORM waste. Such a system may be composed of one or more waste management facilities. This term does not include hazardous waste management systems.

(36) "TENORM waste unit" means a discrete area of land or an excavation used for the landfilling or other disposal of TENORM waste at a TENORM waste management system.

(37) "Total Effective Dose Equivalent" (TEDE) means the overall measured and/or calculated effective dose that takes into account the type of radiation and the nature of each organ or tissue being irradiated.

(38) "Transport" has the meaning specified in ARM 17.50.403.

(39) "Treatment" has the meaning specified in ARM 17.50.403.

(40) "Waste" has the meaning specified in ARM 17.50.502.

(41) "Waste characterization" means the standardized process for analyzing the composition of different waste streams.
