N.J. Admin. Code § 7:27-7.1
The following words and terms, when used in this subchapter, shall have the following meanings unless the context clearly indicates otherwise.
"Adjusted stack height" means the stack height modified by either a stack height adjustment factor or a stack height adjustment in feet.
"Allowable emission" means the emission in any 60-minute period expressed in pounds, computed as set forth in 7:27-7.2(r).
"Commercial fuel" means solid, liquid or gaseous fuels normally produced, manufactured, used or sold for the purpose of creating useful heat.
"Commissioner" means the State Commissioner of Environmental Protection who is the chief administrative officer of the State Department of Environmental Protection.
"Gases" means formless fluids which, under standard conditions, occupy the space of enclosure and which can be changed to the liquid or solid state only by the combined effect of increased pressure and decreased temperature.
"Hydrogen sulfide" means a colorless gas at standard conditions having a molecular composition of one sulfur atom and two hydrogen atoms.
"Liquid particles" means particles which have volume, but are not of rigid shape and which upon collection tend to coalesce and create uniform homogeneous films upon the surface of the collecting media.
"Source operation" means any process or any identifiable part thereof emitting air contaminants into the outdoor atmosphere through one or more stacks or chimneys. For purposes of this definition identical processes shall be considered as separate source operations.
"Stack exit velocity" means the linear velocity in feet per second at which gases enter the outdoor atmosphere from a stack or chimney.
"Stack height" means the vertical distance measured in feet between the point of discharge from the stack or chimney into the outdoor atmosphere and the elevation of the land thereunder.
"Stack or chimney" means a flue, conduit or opening permitting particulate or gaseous emissions into the open air, or constructed or arranged for such purpose.
"Standard conditions" means 70 degrees Fahrenheit and one atmosphere pressure (14.7 psia or 760 mm Hg).
"Sulfur compounds" means all inorganic or organic chemicals having an atom or atoms of sulfur in their chemical structure.
"Sulfur dioxide (SO[2])" means a colorless gas at standard conditions which has the molecular formula SO[2].
"Sulfuric acid (H[2]SO[4])" means a heavy, corrosive, oily, colorless, dibasic, strong acid having the molecular formula H[2]SO[4].
"Sulfur trioxide (SO[3])" means a compound which has the molecular formula SO[3].
"Vapors" means the gaseous form of substances which, under standard conditions, are in the solid or liquid state and which can be changed to these states by either increasing the pressure or decreasing the temperature.
