Current through Register Vol. 50, No. 6, June 20, 2024
A. Definitions. Unless specifically defined
				  in LAC 33:III.111, the terms in this Chapter shall have the meanings normally
				  used in the field of air pollution control. Additionally the following meanings
				  apply, unless the context clearly indicates otherwise.
Affected Source Category
-any facilities
					 of the following source categories located in the parishes of Ascension, East
					 Baton Rouge, Iberville, Livingston, and West Baton Rouge and having the
					 potential to emit 25 TPY or more of VOC, or located in the parishes of
					 Calcasieu and Pointe Coupee and having the potential to emit 50 TPY or more of
					 VOC:
a. organic chemicals, plastics,
				  and synthetic fibers manufacturing industry under Standard Industrial
				  Classification (SIC) codes 2821, 2823, 2824, 2865, and 2869;
b. pesticides manufacturing industry under
				  SIC code 2879;
c. pharmaceutical
				  manufacturing industry under SIC codes 2833, 2834, and 2836; and
d. hazardous waste treatment, storage, and
				  disposal facilities industry under SIC codes 4952, 4953, and 4959.
Affected Volatile Organic Compounds (VOC)
					 Wastewater
- a VOC wastewater stream from an affected source category
					 with either a VOC concentration greater than or equal to 10,000 parts per
					 million by weight (ppmw) or a VOC concentration greater than or equal to 1000
					 ppmw and a flow rate greater than or equal to 10 liters per minute (2.64
					 gallons per minute), as determined in accordance with Subsection H of this
					 Section.
Chemical Manufacturing Process Unit
- the
					 equipment assembled and connected by pipes or ducts to process raw materials
					 and to manufacture an intended product. A chemical manufacturing process unit
					 consists of more than one unit operation. For the purpose of this Section,
					 chemical manufacturing process unit includes air oxidation reactors and their
					 associated product separators and recovery devices; reactors and their
					 associated product separators and recovery devices; distillation units and
					 their associated distillate receivers and recovery devices; associated unit
					 operations; associated recovery devices; and any feed, intermediate and product
					 storage vessels, product transfer racks, and connected ducts and piping. A
					 chemical manufacturing process unit includes pumps, compressors, agitators,
					 pressure relief devices, sampling connection systems, open-ended valves or
					 lines, valves, connectors, instrumentation systems, and control devices or
					 systems. A chemical manufacturing process unit is identified by its primary
					 product.
Components
- includes, but is not limited
					 to, wastewater storage tanks, surface impoundments, drains, junction boxes,
					 lift stations, weirs, and oil-water separators.
Continuously Monitor
- measure at least
					 once every 15 minutes.
Maintenance Wastewater
- wastewater
					 generated by the draining of process fluid from components in the facility
					 prior to or during maintenance activities. Maintenance wastewater can be
					 generated during planned or unplanned shutdowns and periods that are not
					 associated with shutdowns. Examples of activities that can generate maintenance
					 wastewater include descaling of heat exchanger tube bundles, cleaning of
					 distillation column traps, draining of low legs and high point bleeds, draining
					 of pumps, and draining of unrecovered portions of a facility prior to
					 repair.
Plant
-all facilities located within a
					 contiguous area, under common control, and identified by the Plant ID number as
					 assigned by the department, within the parish in which the plant is primarily
					 located, for inclusion in the emissions inventory.
Point of Determination
- each exit point
					 where process wastewater exits the chemical manufacturing process unit.
Properly Operated Biotreatment Unit
- a
					 suspended growth process that generates and recycles biomass to maintain
					 biomass concentrations in the treatment unit. The average concentration of
					 suspended biomass maintained in the aeration basin of a properly operated
					 biotreatment unit shall equal or exceed 1.0 kilogram per cubic meter
					 (kg/m3), measured as total suspended solids.
Volatile Organic Compounds (VOC)
					 Wastewater
- water which, as part of a facility process, has come into
					 contact with VOC and is intended for treatment, disposal, or discharge without
					 further use in a process unit. Examples of potential VOC wastewater are:
					 product or feed tank drawdown; water formed during a chemical reaction; water
					 used to wash impurities from organic products or reactants; water used to cool
					 or quench organic vapor streams through direct contact; and condensed steam
					 from jet ejector systems pulling a vacuum on vessels. Examples of water streams
					 that are not VOC wastewater are: water being used within a facility process;
					 rainfall runoff; fire, safety, and other exigency-use water; spills;
					 once-through noncontact cooling water; cooling tower blowdown; and maintenance
					 wastewater. The VOC content of noncontact cooling water shall be minimized
					 through a leak detection program.
Wet Weather Retention Basin
- an
					 impoundment or tank that is used to store rainfall runoff that would exceed the
					 capacity of the wastewater treatment system until it can be returned to the
					 wastewater treatment system or, if the water meets the applicable discharge
					 limits, discharged without treatment. These units may also be used to store
					 wastewater during periods when the wastewater treatment system is shut down for
					 maintenance or emergencies.
