Current through Register Vol. 50, No. 6, June 20, 2024
A. In addition to the definitions set forth
					 in LAC 33:IX.4707, the following special definitions apply to this Subchapter.
Cooling Water
- water used for contact
						or noncontact cooling, including water used for equipment cooling, evaporative
						cooling tower makeup, and dilution of effluent heat content. The intended use
						of the
cooling water
is to absorb waste heat rejected from the
						process or processes used or from auxiliary operations on the facility's
						premises.
Cooling water
that is used in another industrial
						process either before or after it is used for cooling is considered process
						water rather than
cooling water
for the purposes of
						calculating the percentage of a new offshore oil and gas extraction facility's
						intake flow that is used for cooling purposes in accordance with LAC
						33:IX.4763.C.
Existing Facility
- any facility that
						commenced construction as described in
						40 CFR
						122.29(b)(4) on or before
						January 17, 2002 (or July 17, 2006, for an offshore oil and gas extraction
						facility), and any modification of, or any addition of, a unit at such a
						facility that does not meet the definition of a
new facility
in LAC 33:IX.4707.
Fixed Facility
- a bottom-founded
						offshore oil and gas extraction facility permanently attached to the seabed or
						subsoil of the outer continental shelf (e.g., platforms, guyed towers,
						articulated gravity platforms) or a buoyant facility securely and substantially
						moored so that it cannot be moved without a special effort (e.g., tension leg
						platforms, permanently moored semi-submersibles) and which is not intended to
						be moved during the production life of the well. This definition does not
						include mobile offshore drilling units (MODUs) (e.g., drill ships, temporarily
						moored semi-submersibles, jack-ups, submersibles, tender-assisted rigs, and
						drill barges).
Minimum Ambient Source Water Surface
						Elevation
- the mean low tidal water level for estuaries or oceans. The
						mean low tidal water level is the average height of the low water over at least
						19 years.
New Offshore Oil and Gas Extraction
						Facility
- any building, structure, facility, or installation that
						meets the definition of a
new facility
in LAC 33:IX.4707 and
						is regulated by the Offshore or Coastal Subcategories of the Oil and Gas
						Extraction Point Source Category Effluent Guidelines incorporated by reference
						in LAC 33:IX.4903, but only if it commences construction after July 17,
						2006.
Offshore Liquefied Natural Gas (LNG) Import
						Terminal
- any facility located in waters defined in the federal
						regulations incorporated by reference in LAC 33:IX.4903 that liquefies,
						re-gasifies, transfers, or stores liquefied natural gas.
Sea Chest
- the underwater compartment
						or cavity within the facility or vessel hull or pontoon through which sea water
						is drawn in (for cooling and other purposes) or discharged.
Seafood Processing Vessel
- any offshore
						or nearshore, floating, mobile facility engaged in the processing of fresh,
						frozen, canned, smoked, salted, or pickled seafood or seafood paste, mince, or
						meal.
AUTHORITY NOTE:
						Promulgated in accordance with
						R.S.
						30:2001 et seq., and in particular Section
						2074(B)(3) and (B)(4)
