Hydraulic lift tank means a tank holding hydraulic fluid for a closed-loop mechanical system that uses compressed air or hydraulic fluid to operate lifts, elevators, and other similar devices.
Hydraulic fracturing means the fracturing of underground rock formations, including shale and non-shale formations, by manmade fluid-driven techniques for the purpose of stimulating oil, natural gas, or other subsurface hydrocarbon production.
Flue means a passage for conveying the products of combustion from a gas appliance to the external air.
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.
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.
heat pump means a machine, a device or installation that transfers heat from natural surroundings such as air, water or ground to buildings or industrial applications by reversing the natural flow of heat such that it flows from a lower to a higher temperature. For reversible heat pumps, it may also move heat from the building to the natural surroundings;
Incineration means an engineered process involving burning or combustion of solid waste to thermally degrade waste materials at high temperatures;
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;
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Geothermal fluid means water in any form at temperatures greater than 120
Exfiltration means any unauthorized release of data from within an information system. This includes copying the data through covert network channels or the copying of data to unauthorized media.
Incinerator means any enclosed device that:
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.
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.
combustible waste means non-biodegradable, non- recyclable, non-reusable, non-hazardous solid waste having minimum calorific value exceeding 1500 kcal/kg and excluding chlorinated materials like plastic, wood pulp, etc.;
Fluid means material or substance which flows or moves whether in a semisolid, liquid, sludge, gas, or any other form or state.
Pressurized gas duster means a pressurized product labeled to remove dust from a surface solely by means of mass air or gas flow, including surfaces such as photographs, photographic film negatives, computer keyboards, and other types of surfaces that cannot be cleaned with solvents. “Pressurized Gas Duster” does not include “Dusting Aid.”
High global warming potential hydrofluorocarbons means any hydrofluorocarbons in a particular end use for which EPA’s Significant New Alternatives Policy (SNAP) program has identified other acceptable alternatives that have lower global warming potential. The SNAP list of alternatives is found at 40 CFR part 82, subpart G, with supplemental tables of alternatives available at (http://www.epa.gov/snap/ ).
Emitter means a drip irrigation emission device that delivers water slowly from the system to the soil.
Finished water means the water that is introduced into the distribution system of a public water system and is intended for distribution and consumption without further treatment, except as treatment necessary to maintain water quality in the distribution system (e.g., booster disinfection, addition of corrosion control chemicals).
Valve means a device used to control the flow of water in the irrigation system.
chemical tanker means a ship constructed or adapted and used for the carriage in bulk of any liquid product listed in chapter 17 of the International Bulk Chemical Code;
Diesel means a distillate oil which can be used as fuel for the operation of a compression ignition engine and which has an approximate boiling temperature of between 150 °C to 400 °C;
Electrostatic spray means a method of applying a spray coating in which opposite electric charges are applied to the substrate and the coating. The coating is attracted to the substrate by the electrostatic potential between them.
Filtration means a process for removing particulate matter from water by passage through porous media.
Semisolid means a product that, at room temperature, will not pour, but will spread or deform easily, including but not limited to gels, pastes, and greases.
