Inactive infestation means evidence of infestation by wood-destroying pests, without the presence of such pests.
Infestation means the presence within or around a dwelling of any insects, rodents, or other pests.
explosive actuated fastening device means a tool that is activated by an explosive charge and that is used for driving bolts, nails and similar objects for the purpose of providing fixing;
Plasma arc incinerator means any enclosed device using a high intensity electrical discharge or arc as a source of heat followed by an afterburner using controlled flame combustion and which is not listed as an industrial furnace.
Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.
Contamination means the presence of, or Release on, under, from or to the environment of any Hazardous Substance, except the routine storage and use of Hazardous Substances from time to time in the ordinary course of business, in compliance with Environmental Laws and with good commercial practice.
Weeds means all rank and uncultivated vegetable growth or matter that:
Pests means Birds, Vermin and Insects.
Airborne radioactivity area means a room, enclosure, or area in which airborne radioactive materials, composed wholly or partly of licensed material, exist in concentrations:
Noxious weeds means weeds that are difficult to control effectively, such as Johnson Grass, Kudzu, and multiflora rose.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Destructive device means (i) any explosive, incendiary, or poison gas, bomb, grenade, rocket having a propellant charge of more than four ounces, missile having an explosive or incendiary charge of more than one-quarter ounce, mine, or other similar device; (ii) any weapon, except a shotgun or a shotgun shell generally recognized as particularly suitable for sporting purposes, by whatever name known that will, or may be readily converted to, expel a projectile by the action of an explosive or other propellant, and that has any barrel with a bore of more than one-half inch in diameter that is homemade or was not made by a duly licensed weapon manufacturer, any fully automatic firearm, any sawed-off shotgun or sawed-off rifle as defined in § 18.2-299 or any firearm prohibited from civilian ownership by federal law; and (iii) any combination of parts either designed or intended for use in converting any device into any destructive device described in this subsection and from which a destructive device may be readily assembled. "Destructive device" does not include any device that is not designed or redesigned for use as a weapon, or any device originally designed for use as a weapon and that is redesigned for use as a signaling, pyrotechnic, line-throwing, safety, or other similar device, nor shall it include any antique firearm as defined in subsection G of § 18.2-308.2:2.
Radioactive waste means any waste which contains radioactive material in concentrations which exceed those listed in 10 CFR Part 20, Appendix B, Table II, Column 2.
noxious liquid substance means any substance designated in Appendix II to this Annex or provisionally assessed under the provisions of Regulation 3(4) as falling into Category A, B, C or D.
Contaminated soil means soil that meets all of the following criteria:
Infection means the entry and development or multiplication of an infectious agent in the body of humans and animals that may constitute a public health risk;
Contaminated site means a site where there is a confirmed presence, caused by man, of hazardous substances of such a level that they pose a significant risk to human health or the environment taking into account current and approved future use of the land;
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than one micrometer is rejected by an engineered barrier, primarily through a size exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Active Ingredient means the clinically active material(s) that provide pharmacological activity in a pharmaceutical product (excluding, for the avoidance of doubt, formulation components such as coatings, stabilizers, excipients or solvents, adjuvants or controlled release technologies).
Airborne radioactive material means any radioactive material dispersed in the air in the form of dusts, fumes, particulates, mists, vapors, or gases.
Contaminate means the addition of sediment, any other pollutant or waste, or any illicit or prohibited discharge.
Noxious weed means a plant that when established is highly destructive, competitive, or difficult to control by cultural or chemical practices.
Visual impairment including blindness means an impairment in vision that, even with correction, adversely affects a student's educational performance. The term includes both partial sight and blindness.
Massive Multiauthor Collaboration Site (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site.
Infiltrative surface means designated interface where effluent moves from distribution media or a distribution product into treatment media or original soil. In standard trench or bed systems this will be the interface of the distribution media or product and in-situ soil. Two separate infiltrative surfaces will exist in a mound system and an unlined sand filter, one at the interface of the distribution media and fill sand, the other at the interface of the fill sand and in-situ soil.
