A. Waste Determination Procedures to
Determine Average Volatile Organic (VO) Concentration of a Hazardous Waste at
the Point of Waste Origination
1. An owner or
operator shall determine the average VO concentration at the point of waste
origination for each hazardous waste placed in a waste management unit exempted
under the provisions of LAC 33:V.4725 from using air emission controls in
accordance with standards specified in LAC 33:V.4729-4735, as applicable to the
waste management unit.
a. An initial
determination of the average VO concentration of the waste stream shall be made
before the first time any portion of the material in the hazardous waste stream
is placed in a waste management unit exempted under the provisions of LAC
33:V.4725 from using air emission controls, and thereafter, an initial
determination of the average VO concentration of the waste stream shall be made
for each averaging period that a hazardous waste is managed in the
unit.
b. Perform a new waste
determination whenever changes to the source generating the waste stream are
reasonably likely to cause the average VO concentration of the hazardous waste
to increase to a level that is equal to or greater than the VO concentration
limit specified in LAC 33:V.4725.
2. For a waste determination that is required
by Paragraph A.1 of this Section, the average VO concentration of a hazardous
waste at the point of waste origination shall be determined using either direct
measurement as specified in Paragraph A.3 of this Section or by knowledge as
specified in Paragraph A.4 of this Section.
3. Direct Measurement to Determine Average VO
Concentration of a Hazardous Waste at the Point of Waste Origination
a. Identification. The owner or operator
shall identify and record the point of waste origination for the hazardous
waste.
b. Sampling. Samples of the
hazardous waste stream shall be collected at the point of waste origination in
a manner such that volatilization of organics contained in the waste and in the
subsequent sample is minimized and an adequately representative sample is
collected and maintained for analysis by the selected method.
i. The averaging period to be used for
determining the average VO concentration for the hazardous waste stream on a
mass-weighted average basis shall be designated and recorded. The averaging
period can represent any time interval that the owner or operator determines is
appropriate for the hazardous waste stream, but shall not exceed one
year.
ii. A sufficient number of
samples, but no less than four samples, shall be collected and analyzed for a
hazardous waste determination. All of the samples for a given waste
determination shall be collected within a one-hour period. The average of the
four or more sample results constitutes a waste determination for the waste
stream. One or more waste determinations may be required to represent the
complete range of waste compositions and quantities that occur during the
entire averaging period due to normal variations in the operating conditions
for the source or process generating the hazardous waste stream. Examples of
such normal variations are seasonal variations in waste quantity or
fluctuations in ambient temperature.
iii. All samples shall be collected and
handled in accordance with written procedures prepared by the owner or operator
and documented in a site sampling plan. This plan shall describe the procedure
by which representative samples of the hazardous waste stream are collected
such that a minimum loss of organics occurs throughout the sample collection
and handling process and by which sample integrity is maintained. A copy of the
written sampling plan shall be maintained on-site in the facility operating
records. An example of acceptable sample collection and handling procedures for
a total volatile organic constituent concentration may be found in Method 25D
in 40 CFR Part 60, Appendix A.
iv.
Sufficient information, as specified in the site sampling plan
required under Clause A.3.b.iii of this Section shall be prepared and recorded
to document the waste quantity represented by the samples and, as applicable,
the operating conditions for the source or process generating the hazardous
waste represented by the samples.
c. Analysis. Each collected sample shall be
prepared and analyzed in accordance with Method 25D in 40 CFR Part 60, Appendix
A for the total concentration of volatile organic constituents, or by using one
or more appropriate methods when the individual organic compound concentrations
are identified and summed and the summed waste concentration accounts for and
reflects all organic compounds in the waste with Henry's law constant values at
least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1
Y/X) (which can also be expressed as 1.8 x 10-6
atmospheres/gram-mole/m3) at 25°C. At the owner's or
operator's discretion, the owner or operator may adjust test data obtained by
any appropriate method to discount any contribution to the total volatile
organic concentration that is a result of including a compound with a Henry's
law constant value of less than 0.1 Y/X at 25oC. To
adjust these data, the measured concentration of each individual chemical
constituent contained in the waste is multiplied by the appropriate
constituent-specific adjustment factor (fm25D). If the
owner or operator elects to adjust test data, the adjustment must be made to
all individual chemical constituents with a Henry's law constant value greater
than or equal to 0.1 Y/X at 25oC that are contained
in the waste. Constituent-specific adjustment factors
(fm25D) can be obtained by contacting the Waste and
Chemical Processes Group, Office of Air Quality Planning and Standards,
Research Triangle Park, NC 27711. Other test methods may be used if they meet
one of the following requirements in Clause A.3.c.i or ii of this Section and
provided that the requirement to reflect all organic compounds in the waste
with Henry's law constant values greater than or equal to 0.1 Y/X (which can
also be expressed as 1.8 x 10-6
atmospheres/gram-mole/m3) at 25°C is met:
i. any EPA standard method that has been
validated in accordance with Alternative Validation Procedure for EPA
Waste and Wastewater Methods, 40 CFR Part 63, Appendix D; or
ii. any other analysis method that has been
validated in accordance with the procedures specified in Section 5.1 or Section
5. 3, and the corresponding calculations in Section 6.1 or Section 6. 3, of
Method 301 in 40 CFR Part 63, Appendix A. The data are acceptable if they meet
the criteria specified in Section 6.1 5 or Section 6.3 3 of Method 301. If
correction is required under Section 6.3 3 of Method 301, the data are
acceptable if the correction factor is within the range 0.7 to 1.30. Other
sections of Method 301 are not required.
d. Calculations
i. The average VO concentration (C[BAR]) on a
mass-weighted basis shall be calculated by using the results for all waste
determinations conducted in accordance with Subparagraphs A.3.b and c of this
Section and the following equation.

Image
where:
C[BAR] = average VO concentration of the hazardous waste
at the point of waste origination on a mass-weighted basis, ppmw
i = individual waste determination "i" of the hazardous
waste
n = total number of waste determinations of the
hazardous waste conducted for the averaging period (not to exceed one
year)
Qi = mass quantity of hazardous
waste stream represented by Ci, kg/hr.
QT = total mass quantity of
hazardous waste during the averaging period, kg/hr
Ci = measured VO concentration
of waste determination "i" as determined in accordance with the requirements of
Subparagraph A.3.c of this Section (i.e., the average of the four or more
samples specified in Clause A.3.b.ii of this Section), ppmw
ii. For the purpose of determining
Ci, for individual waste samples analyzed in accordance
with Subparagraph A.3.c of this Section, the owner or operator shall account
for VO concentrations determined to be below the limit of detection of the
analytical method by using the following VO concentration:
(a). if Method 25D in 40 CFR Part 60,
Appendix A is used for the analysis, one-half the blank value determined in the
method at Section 4.4 of Method 25D in 40 CFR Part 60, Appendix A;
(b). if any other analytical method is used,
one-half the sum of the limits of detection established for each organic
constituent in the waste that has a Henry's law constant value at least 0.1
mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X)
(which can also be expressed as 1.8 x 10-6
atmospheres/gram-mole/m3) at 25°C.
e. Provided that the
test method is appropriate for the waste as required under Subparagraph A.3.c
of this Section, the department will determine compliance based on the test
method used by the owner or operator as recorded in accordance with LAC
33:V.4735.
4. Use of
Owner or Operator Knowledge to Determine Average VO Concentration of a
Hazardous Waste at the Point of Waste Origination
a. Documentation shall be prepared that
presents the information used as the basis for the owner's or operator's
knowledge of the hazardous waste stream's average VO concentration. Examples of
information that may be used as the basis for knowledge include: material
balances for the source or process generating the hazardous waste stream;
constituent-specific chemical test data for the hazardous waste stream from
previous testing that are still applicable to the current waste stream;
previous test data for other locations managing the same type of waste stream;
or other knowledge based on information included in manifests, shipping papers,
or waste certification notices.
b.
If test data are used as the basis for knowledge, then the owner or operator
shall document the test method, sampling protocol, and the means by which
sampling variability and analytical variability are accounted for in the
determination of the average VO concentration. For example, an owner or
operator may use organic concentration test data for the hazardous waste stream
that is validated in accordance with Method 301 in 40 CFR Part 63, Appendix A
as the basis for knowledge of the waste.
c. An owner or operator using chemical
constituent-specific concentration test data as the basis for knowledge of the
hazardous waste may adjust the test data to the corresponding average VO
concentration value that would have been obtained had the waste samples been
analyzed using Method 25D in 40 CFR Part 60, Appendix A. To adjust these data,
the measured concentration for each individual chemical constituent contained
in the waste is multiplied by the appropriate constituent-specific adjustment
factor (fm25D).
d. In the event that the administrative
authority and the owner or operator disagree on a determination of the average
VO concentration for a hazardous waste stream using knowledge, then the results
from a determination of average VO concentration using direct measurement as
specified in Paragraph A.3 of this Section shall be used to establish
compliance with the applicable requirements of this Subpart. The administrative
authority may perform or request that the owner or operator perform this
determination using direct measurement. The owner or operator may choose one or
more appropriate methods to analyze each collected sample in accordance with
the requirements of Subparagraph A.3.c of this Section.
B. Waste Determination Procedures
for Treated Hazardous Waste
1. An owner or
operator shall perform the applicable waste determination for each treated
hazardous waste placed in a waste management unit exempted under the provisions
of LAC 33:V.4725 from using air emission controls in accordance with standards
specified in LAC 33:V.4729-4735, as applicable to the waste management unit.
a. An initial determination of the average VO
concentration of the waste stream shall be made before the first time any
portion of the material in the treated waste stream is placed in a waste
management unit exempted under the provisions of LAC 33:V.4725 from using air
emission controls, and thereafter, update the information used for the waste
determination at least once every 12 months following the date of the initial
waste determination.
b. Perform a
new waste determination whenever changes to the process generating or treating
the waste stream are reasonably likely to cause the average VO concentration of
the hazardous waste to increase to a level such that the applicable treatment
conditions specified in LAC 33:V.4725 are not achieved.
2. The owner or operator shall designate and
record the specific provision in LAC 33:V.4725 under which the waste
determination is being performed. The waste determination for the treated
hazardous waste shall be performed using the applicable procedures specified in
Paragraphs B.3-9 of this Section.
3. Procedure to Determine the Average VO
Concentration of a Hazardous Waste at the Point of Waste Treatment
a. Identification. The owner or operator
shall identify and record the point of waste treatment for the hazardous
waste.
b. Sampling. Samples of the
hazardous waste stream shall be collected at the point of waste treatment in a
manner such that volatilization of organics contained in the waste and in the
subsequent sample is minimized and an adequately representative sample is
collected and maintained for analysis by the selected method.
i. The averaging period to be used for
determining the average VO concentration for the hazardous waste stream on a
mass-weighted average basis shall be designated and recorded. The averaging
period can represent any time interval that the owner or operator determines is
appropriate for the hazardous waste stream, but shall not exceed one
year.
ii. A sufficient number of
samples, but no less than four samples, shall be collected and analyzed for a
hazardous waste determination. All of the samples for a given waste
determination shall be collected within a one-hour period. The average of the
four or more sample results constitutes a waste determination for the waste
stream. One or more waste determinations may be required to represent the
complete range of waste compositions and quantities that occur during the
entire averaging period due to normal variations in the operating conditions
for the source or process generating the hazardous waste stream. Examples of
such normal variations are seasonal variations in waste quantity or
fluctuations in ambient temperature.
iii. All samples shall be collected and
handled in accordance with written procedures prepared by the owner or operator
and documented in a site sampling plan. This plan shall describe the procedure
by which representative samples of the hazardous waste stream are collected
such that a minimum loss of organics occurs throughout the sample collection
and handling process and by which sample integrity is maintained. A copy of the
written sampling plan shall be maintained on-site in the facility operating
records. An example of acceptable sample collection and handling procedures for
a total volatile organic constituent concentration may be found in Method 25D
in 40 CFR Part 60, Appendix A.
iv.
Sufficient information, as specified in the site sampling plan
required under Clause B.3.b.iii of this Section, shall be prepared and recorded
to document the waste quantity represented by the samples and, as applicable,
the operating conditions for the process treating the hazardous waste
represented by the samples.
c. Analysis. Each collected sample shall be
prepared and analyzed in accordance with Method 25D in 40 CFR Part 60, Appendix
A for the total concentration of volatile organic constituents, or by using one
or more appropriate methods when the individual organic compound concentrations
are identified and summed and the summed waste concentration accounts for and
reflects all organic compounds in the waste with Henry's law constant values at
least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1
Y/X) (which can also be expressed as 1.8 x 10-6
atmospheres/gram-mole/m3) at 25° C. When the owner
or operator is making a waste determination for a treated hazardous waste that
is to be compared to an average VO concentration at the point of waste
origination or the point of waste entry to the treatment system, to determine
if the conditions of LAC 33:V.4723 or 4725 are met, then the waste samples
shall be prepared and analyzed using the same method or methods as were used in
making the initial waste determinations at the point of waste origination or at
the point of entry to the treatment system. At the owner's or operator's
discretion, the owner or operator may adjust test data obtained by any
appropriate method to discount any contribution to the total VO concentration
that is a result of including a compound with a Henry's law constant value less
than 0.1 Y/X at 25° C. To adjust these data, the measured concentration of each
individual chemical constituent contained in the waste is multiplied by the
appropriate constituent-specific adjustment factor
(fm25D). If the owner or operator elects to adjust test
data, the adjustment must be made to all individual chemical constituents with
a Henry's law constant value greater than or equal to 0.1 Y/X at 25°C that are
contained in the waste. Constituent-specific adjustment factors
(fm25D) can be obtained by contacting the Waste and
Chemical Processes Group, Office of Air Quality Planning and Standards,
Research Triangle Park, NC 27711. Other test methods may be used if they meet
one of the following requirements in Clause B.3.c.i or ii of this Section and
provided that the requirement to reflect all organic compounds in the waste
with Henry's law constant values greater than or equal to 0.1 Y/X (which can
also be expressed as 1.8 x 10-6
atmospheres/gram-mole/m3) at 25° C is met:
i. any EPA standard method that has been
validated in accordance with Alternative Validation Procedure for EPA
Waste and Wastewater Methods, 40 CFR Part 63, Appendix D; or
ii. any other analysis method that has been
validated in accordance with the procedures specified in Section 5.1 or Section
5. 3, and the corresponding calculations in Section 6.1 or Section 6. 3, of
Method 301 in 40 CFR Part 63, Appendix A. The data are acceptable if they meet
the criteria specified in Section 6.1 5 or Section 6.3 3 of Method 301. If
correction is required under Section 6.3 3 of Method 301, the data are
acceptable if the correction factor is within the range 0.7 to 1.30. Other
sections of Method 301 are not required.
d. Calculations. The average VO concentration
(C[BAR]) on a mass-weighted basis shall be calculated by using the results for
all waste determinations conducted in accordance with Subparagraphs B.3.b and c
of this Section and the following equation.

maximum organic vapor pressure for each hazardous waste placed in a tank using
Tank Level 1 controls in accordance with the standards specified in LAC
33:V.4729.
2. An owner or operator
shall use either direct measurement as specified in Paragraph C.3 of this
Section or knowledge of the waste as specified by Paragraph C.4 of this Section
to determine the maximum organic vapor pressure which is representative of the
hazardous waste composition stored or treated in the tank.
3. Direct Measurement to Determine the
Maximum Organic Vapor Pressure of a Hazardous Waste
a. Sampling. A sufficient number of samples
shall be collected to be representative of the waste contained in the tank. All
samples shall be collected and handled in accordance with written procedures
prepared by the owner or operator and documented in a site sampling plan. This
plan shall describe the procedure by which representative samples of the
hazardous waste are collected such that a minimum loss of organics occurs
throughout the sample collection and handling process and by which sample
integrity is maintained. A copy of the written sampling plan shall be
maintained on-site in the facility operating records. An example of acceptable
sample collection and handling procedures may be found in Method 25D in 40 CFR
Part 60, Appendix A.
b. Analysis.
Any appropriate one of the following methods may be used to analyze the samples
and compute the maximum organic vapor pressure of the hazardous waste:
i. Method 25E in 40 CFR Part 60, Appendix
A;
ii. methods described in
American Petroleum Institute Publication 2517, Third Edition, February 1989,
Evaporative Loss from External Floating-Roof Tanks,
incorporated by reference in LAC 33:V.110.A;
iii. methods obtained from standard reference
texts;
iv. ASTM Method 2879-92,
incorporated by reference in LAC 33:V.110.A; and
v. any other method approved by the
administrative authority.
4. Use of Knowledge to Determine the Maximum
Organic Vapor Pressure of the Hazardous Waste. Documentation shall be prepared
and recorded that presents the information used as the basis for the owner's or
operator's knowledge that the maximum organic vapor pressure of the hazardous
waste is less than the maximum vapor pressure limit listed in LAC 33:V.4729 for
the applicable tank design capacity category. An example of information that
may be used is documentation that the hazardous waste is generated by a process
for which, at other locations, it previously has been determined by direct
measurement that the waste maximum organic vapor pressure is less than the
maximum vapor pressure limit for the appropriate tank design capacity category.
D. Procedure for
Determining No Detectable Organic Emissions for the Purpose of Complying with
This Subpart
1. The test shall be conducted
in accordance with the procedures specified in Method 21 of 40 CFR Part 60,
Appendix A. Each potential leak interface (i.e., a location where organic vapor
leakage could occur) on the cover and associated closure devices shall be
checked. Potential leak interfaces that are associated with covers and closure
devices include, but are not limited to: the interface of the cover and its
foundation mounting; the periphery of any opening on the cover and its
associated closure device; and the sealing seat interface on a spring-loaded
pressure relief valve.
2. The test
shall be performed when the unit contains a hazardous waste having an organic
concentration representative of the range of concentrations for the hazardous
waste expected to be managed in the unit. During the test the cover and closure
devices shall be secured in the closed position.
3. The detection instrument shall meet the
performance criteria of Method 21 of 40 CFR Part 60, Appendix A, except the
instrument response factor criteria in Section 3.1 2(a) of Method 21 shall be
for the average composition of the organic constituents in the hazardous waste
placed in the waste management unit, not for each individual organic
constituent.
4. The detection
instrument shall be calibrated before use on each day of its use by the
procedures specified in Method 21 of 40 CFR Part 60, Appendix A.
5. Calibration gases shall be as follows:
a. zero air (less than 10 ppmv hydrocarbon in
air); and
b. a mixture of methane
or n-hexane and air at a concentration of approximately, but less than, 10,000
ppmv methane or n-hexane.
6. The background level shall be determined
according to the procedures in Method 21 of 40 CFR Part 60, Appendix
A.
7. Each potential leak interface
shall be checked by traversing the instrument probe around the potential leak
interface as close to the interface as possible, as described in Method 21 of
40 CFR Part 60, Appendix A. In the case when the configuration of the cover or
closure device prevents a complete traverse of the interface, all accessible
portions of the interface shall be sampled. In the case when the configuration
of the closure device prevents any sampling at the interface and the device is
equipped with an enclosed extension or horn (e.g., some pressure relief
devices), the instrument probe inlet shall be placed at approximately the
center of the exhaust area to the atmosphere.
8. The arithmetic difference between the
maximum organic concentration indicated by the instrument and the background
level shall be compared with the value of 500 ppmv, except when monitoring a
seal around a rotating shaft that passes through a cover opening, in which case
the comparison shall be as specified in Paragraph D.9 of this Section. If the
difference is less than 500 ppmv, then the potential leak interface is
determined to operate with no detectable organic emissions.
9. For the seals around a rotating shaft that
passes through a cover opening, the arithmetic difference between the maximum
organic concentration indicated by the instrument and the background level
shall be compared with the value of 10,000 ppmw. If the difference is less than
10,000 ppmw, then the potential leak interface is determined to operate with no
detectable organic emissions.
