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;

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.
B. Control Requirements. Any person who is
the owner or operator of an affected source category within a plant shall
comply with the following control requirements. Any component of the wastewater
storage, handling, transfer, or treatment facility, if the component contains
an affected VOC wastewater stream, shall be controlled in accordance with
Paragraph B.1, 2, or 3 of this Section. The control requirements shall apply
from the point of determination of an affected VOC wastewater stream until the
affected VOC wastewater stream is either returned to a process unit, disposed
of in an underground injection well, incinerated, or treated to reduce the VOC
content of the wastewater stream by 90 percent and also reduce the VOC content
of the same wastewater stream to less than 1000 ppm by weight. For wastewater
streams that are combined and then treated to remove VOC, the amount of VOC to
be removed from the combined wastewater stream shall be at least equal to the
total amount of VOC that would be removed from each individual stream so that
they meet the reduction criteria mentioned above in this Subsection.

Any wastewater component that becomes subject to this Section by exceeding the
provisions of Subsection G of this Section, or becoming an affected VOC
wastewater stream as defined in Subsection A of this Section, will remain
subject to the requirements of this Section. This will be the case even if the
component later falls below the above-mentioned provisions unless and until
emissions are reduced to a level at or below the controlled emissions level
existing prior to the implementation of the project by which throughput or
emission rate was reduced and less than the applicable exemption levels in
Subsection G of this Section, and if the following conditions are met:
a. the project by which throughput or

of a facility subject to the control requirements of Subsection B of this
Section, shall comply with the following inspection and monitoring
requirements:
1. all seals and covers used to
comply with Paragraph B.1 of this Section shall be inspected according to the
following schedules to ensure compliance with Subparagraphs B.1.f and g of this
Section:
a. initially and semiannually
thereafter to ensure compliance with Subparagraph B.1.f of this Section;
and
b. upon completion of repair to
ensure compliance with Subparagraphs B.1.f and g of this Section;
2. floating roofs and internal

Subparagraph B.2.e of this Section;
3. monitors shall be installed and maintained
as required by this Section to measure operational parameters of any emission
control device or other device installed to comply with Subsection B of this
Section. Such monitoring and parameters shall be sufficient to demonstrate
proper functioning of those devices and be conducted as follows:
a. for an enclosed combustion device
(including, but not limited to, a thermal incinerator, boiler, or process
heater), continuously monitor and record the temperature of the gas stream
either in the combustion chamber or immediately downstream before any
substantial heat exchange;
b. for a
catalytic incinerator, continuously monitor and record the temperature of the
gas stream immediately before and after the catalyst bed;
c. for a condenser (chiller), continuously
monitor and record the temperature of the gas stream at the condenser
exit;
d. for a carbon adsorber,
continuously monitor and record the VOC concentration of the exhaust gas stream
to determine if breakthrough has occurred. If the carbon adsorber does not
regenerate the carbon bed directly in the control device (e.g., a carbon
canister), the exhaust gas stream shall be monitored at intervals no greater
than daily. As an alternative to conducting monitoring, the carbon may be
replaced with fresh carbon at a regular predetermined time interval that is
less than the carbon replacement interval determined by the maximum design flow
rate and the VOC concentration in the gas stream vented to the carbon adsorber.
For pressure-swing adsorption (PSA) systems, as an alternative to monitoring
the VOC concentration of the exhaust gas stream, the temperature of the bed
near the inlet and near the outlet may be continuously monitored and recorded.
Proper operation shall be evidenced by a uniform pattern of temperature
increases and decreases near the inlet and a fairly constant temperature near
the outlet;

continuously monitor for the presence of a flare pilot light using a
thermocouple or any other equivalent device to detect the presence of a
flame;
f. for a steam stripper,
continuously monitor and record the steam flow rate, the wastewater feed mass
flow rate, the wastewater feed temperature, and the condenser vapor outlet
temperature;
g. in lieu of the
monitoring and parameters listed in Subparagraphs D.3.a-f of this Section,
other monitoring and parameters may be approved or required by the
administrative authority*; and
h.
monitoring of the following units is not required:
i. a boiler or process heater with a design
heat input capacity of 44 megawatts or greater;
ii. a boiler or process heater into which the
emission stream is introduced with the primary fuel; and
iii. a boiler or process heater burning
hazardous waste for which the owner or operator:
(a). has been issued a final permit under 40
CFR Part 270 and complies with the requirements of 40 CFR Part 256 Subpart H;
or
(b). has certified compliance
with the interim status requirements of 40 CFR Part 266 Subpart H;
and
4. biological treatment units used to comply
with Paragraph B.3 of this Section shall:
a.

Subsection E of this Section. For existing units, this shall be done as soon as
practicable, but no later than May 15, 2000; and
b. measure the total suspended solids (or
approved alternate parameter) in the aeration basin of the biotreatment unit
weekly.

G. Exemptions
1. Any affected plant with an annual VOC
loading in wastewater, as determined in accordance with Subsection H of this
Section, less than or equal to 10 megagrams (Mg) (11.03 tons) shall be exempt
from the control requirements of Subsection B of this Section.
2. At any affected plant with an annual VOC
loading in wastewater, as determined in accordance with Subsection H of this
Section, greater than 10 Mg (11.03 tons), any person who is the owner or
operator of the affected source category may exempt from the control
requirements of Subsection B of this Section one or more affected VOC
wastewater streams for which the sum of the annual VOC loading in wastewater
for all of the exempted streams is less than or equal to 10 Mg (11.03
tons).
3. If compliance with the
control requirements of Subsection B of this Section would create a safety
hazard in a component of a wastewater storage, handling, transfer, or treatment
facility, the owner or operator may request the administrative authority* to
exempt that component from the control requirements of Subsection B of this
Section. The administrative authority* shall approve the request if justified
by the likelihood and magnitude of the potential injury and if the
administrative authority* determines that reducing or eliminating the hazard is
technologically or economically unreasonable based on the emissions reductions
that would be achieved.
4.
Wastewater components are exempt from the control requirements of Subsection B
of this Section if the overall control of VOC emissions from the wastewater of
affected source categories is at least 90 percent less than the 1990 baseline
emissions inventory, and the following requirements are met:
a. the owner or operator of the wastewater
components shall submit a control plan, no later than 180 days after
promulgation of this rule, to the department and the appropriate regional
office which demonstrates that the overall control of VOC emissions from
wastewater at the affected source categories will be at least 90 percent less
than the 1990 baseline emissions inventory by November 15, 1996. At a minimum,
the control plan shall include the applicable emission point number (EPN); the
plant identification number (PIN); the calendar year 1990 emission rates of
wastewater from affected source categories (consistent with the 1990 baseline
emissions inventory); a plot plan showing the location, EPN, and PIN associated
with a wastewater storage, handling, transfer, or treatment facility; and the
projected calendar year 1996 VOC emission rates. The projected 1996 VOC
emission rates shall be calculated in a manner consistent with the 1990
baseline emissions inventory;
b. in
order to maintain exemption status under this Subsection, the owner or operator
shall submit an annual report no later than March 31 of each year, starting in
1997, to the Office of Environmental Compliance that demonstrates that the
overall control of VOC emissions at the affected source category from which
wastewater is generated during the preceding calendar year is at least 90
percent less than the 1990 baseline emissions inventory. At a minimum, the
report shall include the EPN; the PIN; the throughput of wastewater from
affected source categories; a plot plan showing the location, EPN, and PIN
associated with a wastewater storage, handling, transfer, or treatment
facility; and the VOC emission rates for the preceding calendar year. The
emission rates for the preceding calendar year shall be calculated in a manner
consistent with the 1990 baseline emissions inventory; and
c. all representations in initial control
plans and annual reports become enforceable conditions. It shall be unlawful
for any person to vary from such representations if the variation will cause a
change in the identity of the specific emission sources being controlled or the
method of control of emissions, unless the owner or operator of the wastewater
component submits a revised control plan to the Office of Environmental
Services within 30 days of the change. All control plans and reports shall
include documentation that the overall reduction of VOC emissions from
wastewater at the affected source categories continues to be at least 90
percent less than the 1990 baseline emissions inventory. The emission rates
shall be calculated in a manner consistent with the 1990 baseline emissions
inventory.
5. The owner
or operator of wastewater components subject to the control requirements of
Subsection B of this Section may request an exemption determination from the
administrative authority* if the overall control of VOC emissions from
wastewater at the affected source categories is at least 80 percent less than
the 1990 baseline emissions inventory, and the following requirements are met:
a. each request for an exemption
determination shall be submitted to the Office of Environmental Services. Each
request shall demonstrate that the overall control of VOC emissions from
wastewater at the affected source categories will be at least 80 percent less
than the 1990 baseline emissions inventory. The request shall include the
applicable EPN; the PIN; the calendar year throughput of wastewater from
affected source categories; the VOC emission rates; and a plot plan showing the
location, EPN, and PIN associated with a wastewater storage, handling,
transfer, or treatment facility. The emission rates shall be calculated in a
manner consistent with the 1990 baseline emissions inventory;
b. the administrative authority* shall
approve the exemption for specific wastewater components if it is determined to
be economically unreasonable to control the associated emissions subject to
these regulations, all reasonable controls are applied, and the overall control
of VOC emissions from wastewater at the affected source categories is at least
80 percent less than the 1990 baseline emissions inventory. The administrative
authority* may subsequently direct the holder of an exemption under this
Section to reapply for the exemption if there is good cause to believe that it
has become economically reasonable to meet the requirements of Subsection B of
this Section. Within three months of an administrative authority* request, the
holder of an exemption under this Section shall reapply for the exemption. If
the reapplication for an exemption is denied, the holder of the exemption shall
meet the requirements of Subsection B of this Section as soon as possible, but
no later than two years from the date of denial; and
c. all representations in initial control
plans and annual reports become enforceable conditions. It shall be unlawful
for any person to vary from such representations if the variation will cause a
change in the identity of the specific emission sources being controlled or the
method of control of emissions unless the owner or operator of the wastewater
component submits a revised control plan to the Office of Environmental
Services within 30 days of the change. All control plans and reports shall
include documentation that the overall reduction of VOC emissions at the plant
from wastewater affected source categories continues to be at least 80 percent
less than the 1990 baseline emissions inventory.
6. Any component of a wastewater storage,
handling, transfer, or treatment facility that is subject to the Hazardous
Organic National Emission Standards for Hazardous Air Pollutants (HON)
wastewater provisions or National Emission Standards for Hazardous Air
Pollutants (NESHAPS) Subpart FF (benzene waste operations) or Subpart YYY
(Synthetic Organic Chemical Manufacturing Industry (SOCMI) wastewater
provisions) is exempt from the provisions of this Section.
7. Equipment that is installed temporarily or
is portable (such as containers) is exempt from the provisions of this
Section.
8. Unless specifically
required, any component of a wastewater storage, handling, transfer, or
treatment facility to which the requirements of this Section apply or which is
specifically exempted shall be exempt from the requirements of any other
portion of this Chapter.
9. Any
wastewater sources identified in an enforceable commitment of the U.S.
Environmental Protection Agency Early Reductions Program which grants a
six-year compliance extension to otherwise applicable standards issued under
Section 112(d) of the Clean Air Act are exempted from the provisions of this
Chapter.
H.
Determination of Wastewater Characteristics
1. The characteristics shall be determined at
a location between the point of determination and the point before which the
wastewater stream is exposed to the atmosphere, treated for VOC removal, or
mixed with another wastewater stream. For wastewater streams that, prior to
November 15, 1993, were either actually being mixed or construction had
commenced that would result in the wastewater streams being mixed, this mixing
shall not establish a limit on where the characteristics may be
determined.
2. The flow rate of a
wastewater stream shall be determined on the basis of an annual average by one
of the following methods:
a. the highest
annual quantity of wastewater managed, based on historical records for the most
recent five years of operation, or for the entire time the wastewater stream
has existed if less than five years but at least one year;
b. the maximum design capacity of the
wastewater component;
c. the
maximum design capacity to generate wastewater of the process unit generating
the wastewater stream; or
d.
measurements that are representative of the actual, normal wastewater
generation rates.
3. The
VOC concentration of a wastewater stream shall be determined on the basis of a
flow-weighted annual average by one of the following methods or by a
combination of the methods. If the administrative authority* determines that
the VOC concentration cannot be adequately determined by knowledge of the
wastewater or by bench-scale or pilot-scale test data, the VOC concentration
shall be determined in accordance with Subparagraph H.3.c of this Section. A
VOC with a Henry's Law Constant less than 7.5x10-5
atm-m3/mole at 25°C (and compounds having normal
boiling points of 350°F (177°C) or greater) shall not be included in the
determination of VOC concentration.
a.
Knowledge of the Wastewater. Sufficient information shall be used to document
the VOC concentration. Examples of information include material balances,
records of chemical purchases, or previous test results.
b. Bench-Scale or Pilot-Scale Test Data.
Sufficient information shall be used to demonstrate that the bench-scale or
pilot-scale test concentration data are representative of the actual VOC
concentration.
c. Measurements.
Collect a minimum of three representative samples from the wastewater stream
and determine the VOC concentration for each sample in accordance with
Subsection E of this Section. The VOC concentration of the wastewater stream
shall be the flow-weighted average of the individual samples.
4. The annual VOC loading in
wastewater for a wastewater stream shall be the annual average flow rate
determined in Paragraph H.2 of this Section multiplied by the annual average
VOC concentration determined in Paragraph H.3 of this Section.
5. The annual VOC loading in wastewater for
an affected source category shall be the sum of the annual VOC loading in
wastewater for each affected VOC wastewater stream.
I. Parishes and Compliance Schedules. For the
affected facilities in the parishes of Ascension, Calcasieu, East Baton Rouge,
Iberville, Livingston, Pointe Coupee, and West Baton Rouge, any person who is
the owner or operator of an affected source category within a plant shall be in
compliance with these regulations no later than November 15, 1996. If an
additional affected VOC wastewater stream is generated as a result of a process
change, the wastewater shall be in compliance with this Section upon initial
start-up or by November 15, 1998, whichever is later, unless the owner or
operator demonstrates to the administrative authority* that achieving
compliance will take longer. If this demonstration is satisfactory to the
administrative authority*, compliance shall be achieved as expeditiously as
practicable, but in no event later than three years after the process change.
An existing wastewater stream that becomes an affected VOC wastewater stream
due to a process change must be in compliance with this Section as
expeditiously as practicable, but in no event later than three years after the
process change. A facility that has become subject to this regulation as a
result of a revision of the regulation shall comply with the requirements of
this Section as soon as practicable, but in no event later than one year from
the promulgation of the regulation revision.
