    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the act, in subpart A of part 60, or in subpart VV 
of part 60, and the following terms shall have the specific meanings

extending from the Brooks Range to the Arctic Ocean.
    Asphalt (also known as Bitumen) is a black or dark brown solid or 
semi-solid thermo-plastic material possessing waterproofing and adhesive 
properties. It is a complex combination of higher molecular weight 
organic compounds containing a relatively high proportion of 
hydrocarbons having carbon numbers greater than C25 with a high carbon 
to hydrogen ratio. It is essentially non-volatile at ambient 
temperatures with closed cup flash point of 445 [deg]F (230 [deg]C) or 
greater.
    Equipment means each valve, pump, pressure relief device, sampling 
connection system, open-ended valve or line, and flange or other 
connector in VOC service. For the purposes of recordkeeping and 
reporting only, compressors are considered equipment.
    In hydrogen service means that a compressor contains a process fluid 
that meets the conditions specified in Sec. 60.593(b).
    In light liquid service means that the piece of equipment contains a 
liquid that meets the conditions specified in Sec. 60.593(c).
    Petroleum means the crude oil removed from the earth and the oils 
derived from tar sands, shale, and coal.

    Petroleum refinery means any facility engaged in producing gasoline, 
kerosene, distillate fuel oils, residual fuel oils, lubricants, or other 
products through the distillation of petroleum, or through the 
redistillation, cracking, or reforming of unfinished petroleum 
derivatives.
    Process unit means the components assembled and connected by pipes 
or ducts to process raw materials and to produce intermediate or final 
products from petroleum, unfinished petroleum derivatives, or other 
intermediates. A process unit can operate independently if supplied with 
sufficient feed or raw materials and sufficient storage facilities for 
the product. For the purpose of this subpart, process unit includes any 
feed, intermediate and final product storage vessels (except as 
specified in Sec. 60.482-1(g)), product transfer racks, and connected 
ducts and piping. A process unit includes all equipment as defined in 
this subpart.
