Noise means two times the root mean square of ten standard deviations, each calculated from the zero responses measured at a constant frequency which is a multiple of 1,0 Hz during a period of 30 seconds.
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.
Odor means that property of an air contaminant that affects the sense of smell.
Underground tank means a device meeting the definition of tank whose entire surface area is totally below the surface of and covered by the ground.
Impervious surface means a surface that has been covered with a layer of material so that it is highly resistant to infiltration by water.
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”.)
Underground area means an underground room, such as a basement, cellar, shaft or vault, providing enough space for physical inspection of the exterior of the tank situated on or above the surface of the floor.
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.
Mold means mold, fungus, microbial contamination or pathogenic organisms.
Existing Contamination means any Contamination present on, or under, the Site as of the execution date of this Contract.
Pervious surface means an area that releases as runoff a small portion of the precipitation that falls on it. Lawns, gardens, parks, forests or other similar vegetated areas are examples of surfaces that typically are pervious.
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;
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 an impairment of the quality of the waters of the state by waste to a degree which creates a hazard to the public health through poisoning or through the spread of disease. “Contamination” includes any equivalent effect resulting from the disposal of waste, whether or not waters of the state are affected.
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.
Engine degreaser means a cleaning product designed to remove grease, grime, oil and other contaminants from the external surfaces of engines and other mechanical parts.
Built-Up Area and/or “Covered Area” in relation to a Flat shall mean the floor area of that Flat including the area of balconies and terraces, if any attached thereto, and also the thickness of the walls (external or internal) and the columns and pillars therein Provided That if any wall, column or pillar be common between two Flats, then one-half of the area under such wall column or pillar shall be included in the built-up area of each such Flat.
Contaminated soil means soil that meets all of the following criteria:
Constructed wetlands means areas intentionally designed and created to emulate the water quality improvement function of wetlands for the primary purpose of removing pollutants from stormwater.
Hazardous substance UST system means an UST system that contains a hazardous substance defined in section 101(14) of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (but not including any substance regulated as a hazardous waste under subtitle C) or any mixture of such substances and petroleum, and which is not a petroleum UST system.
Smoke means the gases, particles, or vapors released into the air as a result of combustion, electrical ignition or vaporization, when the apparent or usual purpose of the combustion, electrical ignition or vaporization is human inhalation of the byproducts, except when the combusting or vaporizing of materials contains no tobacco or nicotine and the purpose of the inhalation is solely olfactory, such as, for example, smoke from incense. The term "smoke" includes, but is not limited to, tobacco smoke, electronic cigarette vapors, and cannabis smoke.
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.
Underground storage means storage of gas in a subsurface stratum or formation of the earth.
noise nuisance means an unwanted sound, in an affected area, which is annoying, troublesome, or disagreeable to a person:
medium voltage means the set of nominal voltage levels that lie above low voltage and below high voltage in the range of 1 kV to 44 kV;
