     The following words or terms, when used in this
subchapter, shall have the following meaning, unless the
context clearly indicates otherwise:
     "Alternative fuel" means fuel derived from any source other
than petroleum, natural gas, or coal. Alternative fuel includes,
but is not limited to, biogas, waste-derived fuel, recycled
tires, tire-derived fuel, and wood fuel as defined in
OAC 252:100-19-1.
     "Black liquor solids" means the dry weight of the solids
that enter the recovery furnace in the black liquor.
     "Digester system" means each continuous digester or
each batch digester used for the cooking of wood in white
liquor, and associated flash tank(s), blow tank(s), chip
steamer(s), and condenser(s).
     "Fossil fuel-fired steam generator" means a furnace or
boiler used in the process of burning fossil fuel for the primary
purpose of producing steam by heat transfer.
     "Kraft pulp mill" means any pulp mill process facility
that produces pulp from wood by cooking (digesting) wood
chips in a water solution of sodium hydroxide and sodium sulfide
(white liquor) at high temperature and pressure. Regeneration
of the cooking chemicals through a recovery process is
also considered part of the kraft pulp mill.
     "Lime kiln" means a unit used to calcine lime mud, which
consists primarily of calcium carbonate, into quicklime, which
is calcium oxide.
     "Multiple-effect evaporator system" means the
multiple-effect evaporators and associated condenser(s) and
hotwell(s) used to concentrate the spent cooking liquid that is
separated from the pulp (black liquor).
     "Petroleum and natural gas process equipment" means
the process equipment used to convert crude petroleum and/or
natural gas into refined products. Petroleum and natural gas process
equipment includes, but is not limited to, distillation columns,
treating columns, catalytic cracking units, catalytic reforming
units, sulfur removal equipment, petroleum coke units, flares, heat
exchangers, reboilers, jet ejectors, compressors, recompressors,
and any other auxiliary equipment pertinent to the process.
     "Petroleum and natural gas process facility" means a
facility that is engaged in converting crude petroleum and/or
natural gas into refined products. Petroleum and natural gas
process facilities include petroleum refineries and natural gas
processing plants (as defined in 40 CFR § 60.631), but do not
include petroleum and natural gas production, gathering, and
transportation facilities.
     "Recovery furnace" means either a straight kraft-recovery
furnace or a cross-recovery furnace, and includes the
direct-contact evaporator for a direct-contact furnace.
     "Smelt-dissolving tank" means a vessel used for dissolving
the smelt collected from the recovery furnace.
     "Sulfur recovery unit" means a process device that
recovers elemental sulfur from acid gas.
     "Sweetening unit" means a natural gas processing device that
removes hydrogen sulfide and carbon dioxide from the gas stream.
     "Total reduced sulfur" or "TRS" means the sum of the
compounds hydrogen sulfide, methyl mercaptan, dimethyl sulfide,
and dimethyl disulfide.
