Terminal disease means an incurable and irreversible disease that has been medically confirmed and will, within reasonable medical judgment, produce death within six months.
Disinfection means a process which inactivates pathogenic organisms in water by chemical oxidants or equivalent agents.
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;
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;
Stray radiation means the sum of leakage and scattered radiation.
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.
Irrigation means application of water to land areas to supply the water needs of
Disinfection profile means a summary of Giardia lamblia inactivation through the treatment plant.
Electrical Distance means, for a Generation Capacity Resource geographically located outside the metered boundaries of the PJM Region, the measure of distance, based on impedance and in accordance with the PJM Manuals, from the Generation Capacity Resource to the PJM Region.
Chemical Storage Facility means a building, portion of a building, or exterior area adjacent to a building used for the storage of any chemical or chemically reactive products.
Waterborne disease outbreak means the significant occurrence of an acute infectious illness, epidemiologically associated with the ingestion of water from a public water system which is deficient in treatment, as determined by the Division.
Gasification means the substoichiometric oxidation or steam reformation of a substance to produce a gaseous mixture containing two or more of the following: (i) oxides of carbon; (ii) methane; and (iii) hydrogen;
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.
Irradiation means the exposure of a living being or matter to ionizing radiation.
Disinfect means to eliminate virtually all germs from inanimate surfaces through the use of chemicals or physical agents (e.g., heat). In the child care environment, a solution of ¼ cup household liquid chlorine bleach added to one gallon of water (or one tablespoon bleach to one quart water) and prepared fresh daily is an effective disinfectant for environmental surfaces and other objects. A weaker solution of 1 tablespoon bleach to 1 gallon of cool water is effective for use on toys, eating utensils, etc. Commercial products may also be used.
Bulk gasoline terminal means a gasoline storage facility which receives gasoline from its supply source primarily by pipeline, ship, or barge, and delivers gasoline to bulk gasoline plants or to commercial or retail accounts primarily by tank truck; and has an average daily throughput of more than 76,000 liters (20,000 gallons) of gasoline.
Flexible vinyl adhesive means an aerosol adhesive designed to bond flexible vinyl to substrates. Flexible vinyl means a nonrigid polyvinyl chloride plastic with at least five percent, by weight, of plasticizer content. A plasticizer is a material, such as a high boiling point organic solvent, that is incorporated into a vinyl to increase its flexibility, workability, or distensibility, and may be determined using ASTM Method E260-91 or from product formulation data.
External beam radiation therapy means therapeutic irradiation in which the source of radiation is at a distance from the body.
Slug loading means any pollutant, including oxygen demanding pollutants, released in a discharge at a flow rate and/or pollutant concentration as to cause interference in the POTW.
Invasive plant species means species of plants not historically found in California that spread outside cultivated areas and can damage environmental or economic resources. Invasive species may be regulated by county agricultural agencies as noxious species. Lists of invasive plants are maintained at the California Invasive Plant Inventory and USDA invasive and noxious weeds database.
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.
Airborne radioactivity area means a room, enclosure, or area in which airborne radioactive materials, composed wholly or partly of licensed material, exist in concentrations:
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 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.
Underground injection means the subsurface emplacement of fluids through a bored, drilled or driven well; or through a dug well, where the depth of the dug well is greater than the largest surface dimension. (See also “injection well”.)
Mist spray adhesive means any aerosol which is not a special purpose spray adhesive and which delivers a particle or mist spray, resulting in the formation of fine, discrete particles that yield a generally uniform and smooth application of adhesive to the substrate.
Tank means an enclosed space which is formed by the permanent structure of a ship and which is designed for the carriage of liquid in bulk.
