Ohio Admin. Code 3745-256-84 - Waste determination procedures - tanks, surface impoundments, and containers
(A)
Waste
determination procedure 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 paragraph (C)(1) of rule
3745-256-83 of the
Administrative Code from using air emission controls in accordance with
standards specified in rules
3745-256-85 to
3745-256-88 of the
Administrative Code, 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 paragraph (C)(1) of rule
3745-256-83 of the
Administrative Code 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;
and
(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 paragraph
(C)(1) of rule
3745-256-83 of the
Administrative Code.
(2)
For a waste
determination that is required by paragraph (A)(1) of this rule, 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 rule or by knowledge as specified in paragraph (A)(4) of this
rule.
(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 paragraph
(A)(3)(b)(iii) of this rule, 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 using one or more
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 also can be expressed as 1.8 x 10-6
atmospheres/gram-mole/m3] at twenty-five degrees
Celsius. 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
twenty-five degrees Celsius. 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 shall be made to all
individual chemical constituents with a Henry's law constant value greater than
or equal to 0.1 Y/X at twenty-five degrees Celsius 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 the requirements in paragraph (A)(3)(c)(i) or
(A)(3)(c)(ii) of this rule and provided 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 also can be expressed as 1.8 x
10-6
atmospheres/gram-mole/m3 ] at twenty-five degrees
Celsius, is met.
(i)
Any U.S. 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.
(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 the data 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 on a mass-weighted basis
shall be calculated by using the results for all waste determinations conducted
in accordance with paragraphs (A)(3)(b) and (A)(3)(c) of this rule and the
following equation:
Click to view image
Where:
Click to view image
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 paragraph (A)(3)(c) of this rule (i.e. the average of the four or more samples specified in paragraph (A)(3)(b)(ii) of this rule), parts per million by weight (ppmw).
(ii)
To determine
Ci, for individual waste samples analyzed in accordance
with paragraph (A)(3)(c) of this rule, 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 values at least 0.1
mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X)
[which also can be expressed as 1.8 x 10-6
atmospheres/gram-mole/m3] at twenty-five degrees
Celsius.
(e)
Provided that the
test method is appropriate for the waste as required under paragraph (A)(3)(c)
of this rule, Ohio EPA will determine compliance based on the test method used
by the owner or operator as recorded pursuant to paragraph (F)(1) of rule
3745-256-90 of the
Administrative Code.
(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 are 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 which 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 director 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 rule shall be used to
establish compliance with the applicable requirements of rules
3745-256-80 to
3745-256-90 of the
Administrative Code. The director 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 paragraph (A)(3)(c) of this
rule.
(B)

or (C)(4) of rule
3745-256-83 of the
Administrative Code from using air emission controls, and thereafter update the
information used for the waste determination at least once every twelve months
following the date of the initial waste determination; and
(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 paragraph (C)(2), (C)(3), or (C)(4) of rule
3745-256-83 of the
Administrative Code are not achieved.
(2)
The owner or
operator shall designate and record the specific provision in paragraph (C)(2)

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 process generating or treating
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

total concentration of volatile organic constituents, or using one or more
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 also can be expressed as 1.8 x 10-6
atmospheres/gram-mole/m3] at twenty-five degrees
Celsius. 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 paragraphs (C)(2)(a) to (C)(2)(f) of
rule 3745-205-82 of the
Administrative Code, or paragraphs (C)(2)(a) to (C)(2)(f) of rule 3745-265-83
of the Administrative Code 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 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 less than 0.1
Y/X at twenty-five degrees Celsius. To adjust these data, the measured
concentration of each individual chemical constituent 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 shall be
made to all individual chemical constituents with a Henry's law constant value
greater than or equal to 0.1 Y/X at twenty-five degrees Celsius 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 meet the
requirements in paragraph (A)(3)(c)(i) or (A)(3)(b)(ii) of this rule and
provided 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 also can be
expressed as 1.8 x 10-6
atmospheres/gram-mole/m3] at twenty-five degrees
Celsius, is met.

interfaces that are associated with covers and closure devices include, but are
not limited to the interface of the cover and the cover's foundation mounting;
the periphery of any opening on the cover and the cover's 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 the instrument's 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 ten parts per million by volume
(ppmv) hydrocarbon in air), and
(b)
A mixture of
methane or n-hexane and air at a concentration of approximately, but less than,
ten thousand 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 five hundred 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 rule. If the
difference is less than five hundred 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 ten
thousand ppmw. If the difference is less than ten thousand ppmw, then the
potential leak interface is determined to operate with no detectable organic
emissions.
