Pressure vessel means containers for the containment of pressure, either internal or external. This pressure may be obtained from an external source or by the application of heat from a direct or indirect source, or any combination thereof.
Pressure means the total load or force per unit area acting on a surface.
Backpressure means a pressure (caused by a pump, elevated tank or piping, boiler, or other means) on the consumer's side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow.
Reid vapor pressure means the vapor pressure of crude oil or other volatile petroleum products at 100 degrees Fahrenheit as determined by the latest edition of ASTM D6377 (RVPE): Standard Test Method for Determination of Vapor Pressure of Crude Oil.
True vapor pressure means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute (API) Bulletin 2517, Evaporation Loss from External Floating Roof Tanks, 1980. The API procedure may not be applicable to some high viscosity or high pour crudes. Available estimates of true vapor pressure may be used in special cases such as these.
Hydric soil means a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part.
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/ ).
Drywell means an unlined or partially lined underground pit (regardless of geometry) into which drainage from roofs, basement floors, water softeners or other non-wastewater sources is discharged and from which the liquid seeps into the surrounding soil.
Natural Gas Liquids means those hydrocarbon components that can be recovered from natural gas as a liquid including, but not limited to, ethane, propane, butanes, pentanes plus, and condensates;
high voltage means the classification of an electric component or circuit, if its working voltage is > 60 V and ≤ 1500 V DC or > 30 V and ≤ 1000 V AC root mean square (rms).
Sewage sludge weight means the weight of sewage sludge, in dry U.S. tons, including admixtures such as liming materials or bulking agents. Monitoring frequencies for sewage sludge parameters are based on the reported sludge weight generated in a calendar year (use the most recent calendar year data when the NPDES permit is up for renewal).
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;
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;
Diameter means the diameter of the stem of a tree measured outside the bark at a specified point of measurement.
Blendstock means and includes any petroleum product component of motor fuel, such as naphtha, reformate, or toluene; or any oxygenate that can be blended for use in a motor fuel.
MAOP means the maximum allowable operating pressure of the Maui Pipeline or any part of it, as set out in Schedule 6.
Geothermal fluid means water in any form at temperatures greater than 120
Ambient air means that portion of the atmosphere, external to buildings, to which the general public has access.
Heat input means the product (expressed in mmBtu/time) of the gross calorific value of the fuel (expressed in Btu/lb) and the fuel feed rate into the combustion device (expressed in mass of fuel/time) and does not include the heat derived from preheated combustion air, recirculated flue gases, or ex- haust from other sources.
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;
Landfill Gas means any gas derived through any biological process from the decomposition of waste buried within a waste disposal site.
voltage means the root-mean-square value of electrical potential between two conductors.
Positive pressure respirator means a respirator in which the pressure inside the respiratory inlet covering exceeds the ambient air pressure outside the respirator.
Air contaminant source means any and all sources of emission of air contaminants whether privately or publicly owned or operated (Section 19-2-102(2)).
High voltage bus means the electrical circuit, including the coupling system for charging the REESS that operates on a high voltage.
Sailboat means the same as that term is defined in Section 73-18-2.
