(A) The owner or operator of a facility
with process vents associated with distillation, fractionation, thin-film
evaporation, solvent extraction or air or steam stripping operations managing
hazardous wastes with organic concentrations at least ten parts per million by
weight shall either: (1) Reduce total organic emissions from all affected
process vents at the facility below 1.4 kilograms per hour (kg/h) [three pounds
per hour (lb/h)] and 2.8 megagrams per year (Mg/yr) [3.1 ton per year
(tons/yr)]; or (2) Reduce, by use of a control device, total organic
emissions from all affected process vents at the facility by ninety-five weight
per cent. (B) If the owner or operator installs a closed-vent system
and control device to comply with paragraph (A) of this rule, the closed-vent
system and control device shall meet the requirements of rule 3745-256-33 of
the Administrative Code. (C) Determinations of vent emissions and emission
reductions or total organic compound concentrations achieved by add-on control
devices may be based on engineering calculations or performance tests. If
performance tests are used to determine vent emissions, emission reductions, or
total organic compound concentrations achieved by add-on control devices, the
performance tests shall conform with the requirements of paragraph (C) of rule
3745-256-34 of the Administrative Code. (D) When an owner or operator and the director do not agree
on determinations of vent emissions or emission reductions or total organic

Administrative Code after December 8, 1997, due to an action other than those
described in paragraph (A)(2)(c) of this rule shall comply with all applicable
requirements immediately (i.e., shall have control devices installed and
operating on the date the facility or unit becomes subject to rules 3745-256-30
to 3745-256-35 of the Administrative Code; the thirty-month implementation
schedule does not apply). (B) A control device involving vapor
recovery (e.g., a condenser or adsorber) shall be designed and operated to
recover the organic vapors vented to the control device with an efficiency of
ninety-five weight per cent or greater unless the total organic emission limits
of paragraph (A)(1) of rule 3745-256-32 of the Administrative Code for all
affected process vents can be attained at an efficiency less than ninety-five
weight per cent. (C) An enclosed combustion device (e.g.,
a vapor incinerator, boiler, or process heater) shall be designed and operated
to reduce the organic emissions vented to it by ninety-five weight per cent or
greater; to achieve a total organic compound concentration of twenty parts per
million by volume (ppmv), expressed as the sum of the actual compounds, not
carbon equivalents, on a dry basis corrected to three per cent oxygen; or to
provide a minimum residence time of 0.50 seconds at a minimum temperature of
seven hundred sixty degrees Celsius. If a boiler or process heater is used as
the control device, then the vent stream shall be introduced into the flame
combustion zone of the boiler or process heater. (D) (1) A flare shall be
designed for and operated with no visible emissions as determined by the
methods specified in paragraph (E)(1) of this rule, except for periods not to
exceed a total of five minutes during any two consecutive hours. (2) A flare shall be
operated with a flame present at all times, as determined by the methods
specified in paragraph (F)(2)(c) of this rule. (3) A flare shall be used
only if the net heating value of the gas being combusted is 11.2 MegaJoules per
standard cubic meter of gas (MJ/scm) [three hundred British thermal units per
standard cubic foot (Btu/scf)] or greater, if the flare is steam-assisted or
air-assisted; or if the net heating value of the gas being combusted is 7.45
MJ/scm (two hundred Btu/scf) or greater if the flare is non-assisted. The net
heating value of the gas being combusted shall be determined by the methods
specified in paragraph (E)(2) of this rule. (4) (a) A steam-assisted or non-assisted flare shall be designed for
and operated with an exit velocity, as determined by the methods specified in
paragraph (E)(3) of this rule, of less than 18.3 meters per second (m/s) [sixty
feet per second (ft/s)], except as provided in paragraphs (D)(4)(b) and
(D)(4)(c) of this rule. (b) A steam-assisted or non-assisted flare designed for and
operated with an exit velocity, as determined by the methods specified in
paragraph (E)(3) of this rule, equal to or greater than 18.3 m/s (sixty ft/s)
but less than one hundred twenty-two m/s (four hundred ft/s) is allowed if the
net heating value of the gas being combusted is greater than 37.3 MJ/scm (one
thousand Btu/scf). (c) A steam-assisted or non-assisted flare designed for and
operated with an exit velocity, as determined by the methods specified in
paragraph (E)(3) of this rule, less than the velocity, Vmax, as determined by the method specified in
paragraph (E)(4) of this rule, and less than one hundred twenty-two m/s (four
hundred ft/s) is allowed. (5) An air-assisted flare
shall be designed and operated with an exit velocity less than the velocity,
Vmax, as determined by the method

comply with this rule shall be steam-assisted, air-assisted, or
non-assisted. (E) (1) Reference method 22
in 40 CFR Part 60 shall be used to determine the compliance of a flare with the
visible emission provisions of rules 3745-256-30 to 3745-256-35 of the
Administrative Code. The observation period is two hours and shall be used
according to method 22. (2) The net heating value
of the gas being combusted in a flare shall be calculated using the following
equation: (2).jpg) Where: HT =
Net heating value of the sample, MJ/scm; where the net enthalpy per mole (mol)
of offgas is based on combustion at twenty-five degrees Celsius and seven
hundred sixty millimeters of mercury (mm Hg), but the standard temperature for
determining the volume corresponding to one mol is twenty degrees
Celsius; K = Constant, 1.74 x 10-7 (1/ppm) (g mol/scm) (MJ/kcal) where standard
temperature for (g mol/scm) is twenty degrees Celsius; ppm means parts per
million, g mol/scm means gram mole per standard cubic meter of gas, MJ/kcal
means MegaJoules per kilocalorie; Ci =
Concentration of sample component i in ppm on a wet basis, as measured for
organics by reference method 18 in 40 CFR Part 60 and measured for hydrogen and
carbon monoxide by ASTM D1946-82 (incorporated by reference in rule 3745-50-11
of the Administrative Code); and Hi =
Net heat of combustion of sample component i, kcal/g mol at twenty-five degrees
Celsius and seven hundred sixty mm Hg. The heats of combustion may be
determined using ASTM D2382-83 (incorporated by reference as specified in rule
3745-50-11 of the Administrative Code) if published values are not available or
cannot be calculated. (3) The actual exit
velocity of a flare shall be determined by dividing the volumetric flow rate
(in units of standard temperature and pressure), as determined by reference
method 2, method 2A, method 2C, or method 2D in 40 CFR Part 60 as appropriate,
by the unobstructed (free) cross-sectional area of the flare tip. (4) The maximum allowed
velocity in m/s, Vmax, for a flare
complying with paragraph (D)(4)(c) of this rule shall be determined by the
following equation: (4).jpg) Where: HT =
The net heating value as determined in paragraph (E)(2) of this rule. 28.8 = Constant. 31.7 = Constant. (5) The maximum allowed
velocity in m/s, Vmax, for an
air-assisted flare shall be determined by the following equation: Vmax =
8.706 + 0.7084 (HT) Where: 8.706 = Constant. 0.7084 = Constant. HT =
The net heating value as determined in paragraph (E)(2) of this rule. (F) The owner or operator shall monitor
and inspect each control device required to comply with this rule to ensure
proper operation and maintenance of the control device by implementing the
following requirements: (1) Install, calibrate,
maintain, and operate according to the manufacturer's specifications a
flow indicator that provides a record of vent stream flow from each affected

(C) Performance tests to determine compliance with paragraph (A) of rule 3745-256-32 of the Administrative Code and with the total organic compound concentration limit of paragraph (C) of rule 3745-256-33 of the Administrative Code shall comply with the following: (1) Performance tests to determine total organic compound concentrations and mass flow rates entering and exiting control devices shall be conducted and data reduced in accordance with the following reference methods and calculation procedures: (a) Method 2 in 40 CFR Part 60 for velocity and volumetric flow rate. (b) Method 18 or method 25A in 40 CFR Part 60 appendix A, for organic content. If method 25A is used, the organic hazardous air pollutants (HAP) used as the calibration gas shall be the single organic HAP representing the largest per cent by volume of the emissions. The use of method 25A is acceptable if the response from the high-level calibration gas is at least twenty times the standard deviation of the response from the zero calibration gas when the instrument is zeroed on the most sensitive scale. (c) Each performance test shall consist of three separate runs; each run conducted for at least one hour under the conditions that exist when the hazardous waste management unit is operating at the highest load or capacity level reasonably expected to occur. For the purpose of determining total organic compound concentrations and mass flow rates, the average of results of all runs shall apply. The average shall be computed on a time-weighted basis. (d) Total organic mass flow rates shall be determined by the following equation: (i) For sources utilizing method 18. (1)(d)(i).jpg) Where: Eh = Total organic mass flow rate, kilograms per hour (kg/h); Q2sd = Volumetric flow rate of gases entering or exiting control device, as determined by method 2, standard cubic meter of dry gas per hour (dscm/h); n = Number of organic compounds in the vent gas; Ci = Organic concentration in ppm, dry basis, of compound i in the vent gas, as determined by method 18; MWi = Molecular weight of organic compound i in the vent gas, kilogram per kilogram mole (kg/kg-mol); 0.0416 = Conversion factor for molar volume, kg-mol/m3 [at two nundred ninety-three Kelvin and seven hundred sixty milligrams of mercury (mm Hg); 10-6 = Conversion from ppm. (ii) For sources utilizing method 25A. Eh = (Q)(C)(MW)(0.0416)(10-6) Where: Eh = Total organic mass flow rate, kg/h; Q = Volumetric flow rate of gases entering or exiting control device, as determined by method 2, dscm/h; C = Organic concentration in ppm, dry basis, as determined by method 25A; MW = Molecular weight of propane, 44; 0.0416 = Conversion factor for molar volume, kg-mol/m3 (at two hundred ninety-three Kelvin and seven hundred sixty mm Hg); 10-6 = Conversion from ppm. (e) The annual total organic emission rate shall be determined by the following equation: EA = (Eh)(H) Where: EA = Total organic mass emission rate, kilograms per year (kg/y); Eh = Total organic mass flow rate for the process vent, kg/h; H = Total annual hours of operations for the affected unit, h. (f) Total organic emissions from all affected process vents at the facility shall be determined by summing the hourly total organic mass emission rates [Eh, as determined in paragraph (C)(1)(d) of this rule] and by summing the annual total organic mass emission rates [EA, as determined in paragraph (C)(1)(e) of this rule] for all affected process vents at the facility. (2) The owner or operator shall record such process information as may be necessary to determine the conditions of the performance tests. Operations during periods of startup, shutdown, and malfunction shall not constitute representative conditions for the purpose of a performance test. (3) The owner or operator of an affected facility shall provide, or cause to be provided, performance testing facilities as follows: (a) Sampling ports adequate for the test methods specified in paragraph (C)(1) of this rule. (b) Safe sampling platforms. (c) Safe access to sampling platforms. (d) Utilities for sampling and testing equipment. (4) For the purpose of making compliance determinations, the time-weighted average of the results of the three runs shall apply. In the event that a sample is accidentally lost or conditions occur in which one of the three runs shall be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances beyond the owner or operator's control, compliance may, upon the director's approval, be determined using the average of the results of the two other runs. (D) To show that a process vent associated with a hazardous waste distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation is not subject to the requirements of rules 3745-256-30 to 3745-256-35 of the Administrative Code, the owner or operator shall make an initial determination that the time-weighted, annual average total organic concentration of the waste managed by the waste management unit is less than ten parts per million by weight (ppmw) using one of the following two methods: (1) Direct measurement of the organic concentration of the waste using the following procedures: (a) The owner or operator shall take a minimum of four grab samples of waste for each waste stream managed in the affected unit under process conditions expected to cause the maximum waste organic concentration. (b) For waste generated on-site, the grab samples shall be collected at a point before the waste is exposed to the atmosphere such as in an enclosed pipe or other closed system that is used to transfer the waste after generation to the first affected distillation fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation. For waste generated offsite, the grab samples shall be collected at the inlet to the first waste management unit that receives the waste provided the waste has been transferred to the facility in a closed system such as a tank truck and the waste is not diluted or mixed with other waste. (c) Each sample shall be analyzed and the total organic concentration of the sample shall be computed using method 9060A of "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," U.S. EPA publication SW-846; or analyzed for its individual organic constituents. (d) The arithmetic mean of the results of the analyses of the four samples shall apply for each waste stream managed in the unit in determining the time-weighted, annual average total organic concentration of the waste. The time-weighted average is to be calculated using the annual quantity of each waste stream processed and the mean organic concentration of each waste stream managed in the unit. (2) Using knowledge of the waste to determine that its total organic concentration is less than ten ppmw. Documentation of the waste determination is required. Examples of documentation that shall be used to support a determination under this provision include production process information documenting that no organic compounds are used, information that the waste is generated by a process that is identical to a process at the same or another facility that has previously been demonstrated by direct measurement to generate a waste stream having a total organic content less than ten ppmw, or prior speciation analysis results on the same waste stream where it also can be documented that no process changes have occurred since that analysis that could affect the waste total organic concentration. (E) The determination that distillation fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operations manage hazardous wastes with time-weighted annual average total organic concentrations less than ten ppmw shall be made as follows: (1) By the effective date that the facility becomes subject to rules 3745-256-30 to 3745-256-35 of the Administrative Code or by the date when the waste is first managed in a waste management unit, whichever is later; and (2) For continuously generated waste, annually; or (3) Whenever there is a change in the waste being managed or a change in the process that generates or treats the waste. (F) When an owner or operator and the director do not agree on whether a distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation manages a hazardous waste with organic concentrations of at least ten ppmw based on knowledge of the waste, the dispute may be resolved using direct measurement as specified at paragraph (D)(1) of this rule.

reference in rule 3745-50-11 of the Administrative Code); (2) Method 9060A
(incorporated by reference in rule 3745-50-11 of the Administrative Code) of
"Test Methods for Evaluating Solid Waste," U.S. EPA publication
SW-846 or analyzed for its individual organic constituents; or (3) Application of the
knowledge of the nature of the hazardous waste stream or the process by which
the hazardous waste stream was produced. Documentation of a waste determination
by knowledge is required. Examples of documentation that shall be used to
support a determination under this provision include production process
information documenting that no organic compounds are used, information that
the waste is generated by a process that is identical to a process at the same
or another facility that has previously been demonstrated by direct measurement
to have a total organic content less than ten per cent, or prior speciation
analysis results on the same waste stream where it also can be documented that
no process changes have occurred since that analysis that could affect the
waste total organic concentration. (E) If an owner or operator determines
that a piece of equipment contains or contacts a hazardous waste with organic
concentrations at least ten per cent by weight, the determination can be
revised only after following the procedures in paragraph (D)(1) or (D)(2) of
this rule. (F) When an owner or operator and the
director do not agree on whether a piece of equipment contains or contacts a
hazardous waste with organic concentrations at least ten per cent by weight,
the procedures in paragraph (D)(1) or (D)(2) of this rule can be used to
resolve the dispute. (G) Samples used in determining the
percent organic content shall be representative of the highest total organic
content hazardous waste that is expected to be contained in or contact the
equipment. (H) To determine if pumps or valves are
in light liquid service, the vapor pressures of constituents may be obtained
from standard reference texts or may be determined by ASTM
D2879-86. (I) Performance tests to determine if a
control device achieves ninety-five weight per cent organic emission reduction
shall comply with the procedures of paragraphs (C)(1) to (C)(4) of rule
3745-256-34 of the Administrative Code. [Comment: For dates of non-regulatory government
publications, publications of recognized organizations and associations,

Rule 3745-256-81 | Definitions - air emission standards for tanks, surface impoundments, and containers.
As used in rules 3745-256-80 to 3745-256-90 of the
Administrative Code, all terms not defined herein have the meaning given in
Chapters 3745-50, 3745-51, 3745-52, 3745-53, 3745-54 to 3745-57, 3745-65 to
3745-69, 3745-205, 3745-256, and 3745-266 of the Administrative Code and the
Resource Conservation and Recovery Act. (A) "Average volatile organic
concentration" or "average VO concentration" means the
mass-weighted average volatile organic concentration of a hazardous waste as
determined in accordance with the requirements of rule 3745-256-84 of the
Administrative Code. (B) [Reserved.] (C) (1) "Closure
device" means a cap, hatch, lid, plug, seal, valve, or other type of
fitting that blocks an opening in a cover such that when the device is secured
in the closed position the closure device prevents or reduces air pollutant
emissions to the atmosphere. Closure devices include devices that are
detachable from the cover (e.g., a sampling port cap), manually operated (e.g.,
a hinged access lid or hatch), or automatically operated (e.g., a spring-loaded
pressure relief valve). (2) "Continuous
seal" means a seal that forms a continuous closure that completely covers
the space between the edge of the floating roof and the wall of a tank. A
continuous seal may be a vapor-mounted seal, liquid-mounted seal, or metallic
shoe seal. A continuous seal may be constructed of fastened segments so as to
form a continuous seal. (3) "Cover"
means a device that provides a continuous barrier over the hazardous waste
managed in a unit to prevent or reduce air pollutant emissions to the
atmosphere. A cover may have openings (such as access hatches, sampling ports,
gauge wells) that are necessary for operation, inspection, maintenance, and
repair of the unit on which the cover is used. A cover may be a separate piece
of equipment which can be detached and removed from the unit or a cover may be
formed by structural features permanently integrated into the design of the
unit. (D) [Reserved.] (E) (1) "Enclosure"
means a structure that surrounds a tank or container, captures organic vapors
emitted from the tank or container, and vents the captured vapors through a
closed-vent system to a control device. (2) "External
floating roof" means a pontoon-type or double-deck type cover that rests
on the surface of the material managed in a tank with no fixed
roof. (F) (1) "Fixed
roof" means a cover that is mounted on a unit in a stationary position and
does not move with fluctuations in the level of the material managed in the
unit. (2) "Floating
membrane cover" means a cover consisting of a synthetic flexible membrane
material that rests upon and is supported by the hazardous waste being managed
in a surface impoundment. (3) "Floating
roof" means a cover consisting of a double deck, pontoon single deck, or
internal floating cover which rests upon and is supported by the material being
contained, and is equipped with a continuous seal. (G) [Reserved.] (H) "Hard-piping" means pipe or
tubing that is manufactured and properly installed in accordance with relevant
standards and good engineering practices. (I) (1) "In light
material service" means the container is used to manage a material for
which both the vapor pressure of one or more of the organic constituents in the
material is greater than 0.3 kilopascals (kPa) at twenty degrees Celsius; and
the total concentration of the pure organic constituents having a vapor
pressure greater than 0.3 kPa at twenty degrees Celsius is equal to or greater
than twenty per cent by weight. (2) "Internal
floating roof" means a cover that rests or floats on the material surface
(but not necessarily in complete contact with the material surface) inside a
tank that has a fixed roof. (J) [Reserved.] (K) [Reserved.] (L) "Liquid-mounted seal" means
a foam or liquid-filled primary seal mounted in contact with the hazardous
waste between the tank wall and the floating roof continuously around the
circumference of the tank. (M) (1) "Malfunction" means any sudden, infrequent,
and not reasonably preventable failure of air pollution control equipment,
process equipment, or a process to operate in a normal or usual manner.
Failures that are caused in part by poor maintenance or careless operation are
not malfunctions. (2) "Maximum organic
vapor pressure" means the sum of the individual organic constituent
partial pressures exerted by the material contained in a tank, at the maximum
vapor pressure-causing conditions (i.e., temperature, agitation, pH effects of
combining wastes, etc.) reasonably expected to occur in the tank. For the
purpose of rules 3745-256-80 to 3745-256-90 of the Administrative Code, maximum
organic vapor pressure is determined using the procedures specified in
paragraph (C) of rule 3745-256-84 of the Administrative Code. (3) "Metallic shoe
seal" means a continuous seal that is constructed of metal sheets which
are held vertically against the wall of the tank by springs, weighted levers,
or other mechanisms and is connected to the floating roof by braces or other
means. A flexible coated fabric (envelope) spans the annular space between the
metal sheet and the floating roof. (N) "No detectable organic
emissions" means no escape of organics to the atmosphere as determined
using the procedure specified in paragraph (D) of rule 3745-256-84 of the
Administrative Code. (O) [Reserved.] (P) (1) "Point of waste
origination" means as follows: (a) When the facility owner or operator is the generator of
the hazardous waste, the point of waste origination means the point where a
waste produced by a system, process, or waste management unit is determined to
be a "hazardous waste" as defined in Chapter 3745-51 of the
Administrative Code. [Comment: In this case, this term is being
used in a manner similar to the use of the term "point of generation"
in air standards established for waste management operations under authority of
the Clean Air Act in 40 CFR Part 60, Part 61, and Part 63.] (b) When the facility owner and operator are not the
generator of the hazardous waste, point of waste origination means the point
where the owner or operator accepts delivery or takes possession of the
hazardous waste. (2) "Point of waste
treatment" means the point where a hazardous waste to be treated in
accordance with paragraph (C)(2) of rule 3745-256-83 of the Administrative Code
exits the treatment process. Any waste determination shall be made before the
waste is conveyed, handled, or otherwise managed in a manner that allows the
waste to volatilize to the atmosphere. (Q) [Reserved.] (R) [Reserved.] (S) (1) "Safety
device" means a closure device such as a pressure relief valve, frangible
disc, fusible plug, or any other type of device which functions exclusively to
prevent physical damage or permanent deformation to a unit or the unit's
air emission control equipment by venting gases or vapors directly to the
atmosphere during unsafe conditions resulting from an unplanned, accidental, or
emergency event. For the purpose of rules 3745-256-80 to 3745-256-90 of the
Administrative Code, a safety device is not used for routine venting of gases
or vapors from the vapor headspace underneath a cover such as during filling of
the unit or to adjust the pressure in this vapor headspace in response to
normal daily diurnal ambient temperature fluctuations. A safety device is
designed to remain in a closed position during normal operations and open only
when the internal pressure, or another relevant parameter, exceeds the device
threshold setting applicable to the air emission control equipment as
determined by the owner or operator based on manufacturer recommendations,
applicable regulations, fire protection and prevention codes, standard
engineering codes and practices, or other requirements for the safe handling of
flammable, ignitable, explosive, reactive, or hazardous materials. (2) "Single-seal
system" means a floating roof having one continuous seal. This seal may be
vapor-mounted, liquid-mounted, or a metallic shoe seal. (T) [Reserved.] (U) [Reserved.] (V) (1) "Vapor-mounted
seal" means a continuous seal that is mounted such that there is a vapor
space between the hazardous waste in the unit and the bottom of the
seal. (2) "Volatile
organic concentration" or "VO concentration" means the fraction
by weight of the volatile organic compounds contained in a hazardous waste
expressed in terms of parts per million (ppmw) as determined by direct
measurement or by knowledge of the waste in accordance with the requirements of
rule 3745-256-84 of the Administrative Code. To determine the VO concentration
of a hazardous waste, organic compounds with a Henry's law constant value
of 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 shall be
included. The appendix to rule 3745-256-84 of the Administrative Code presents
a list of compounds known to have a Henry's law constant value less than
the cutoff level. (W) (1) "Waste
determination" means performing all applicable procedures in accordance
with the requirements of rule 3745-256-84 of the Administrative Code to
determine whether a hazardous waste meets standards specified in rule
3745-256-80 to 3745-256-90 of the Administrative Code. Examples of a waste
determination include performing the procedures in accordance with the
requirements of rule 3745-256-84 of the Administrative Code to determine the
average VO concentration of a hazardous waste at the point of waste
origination; the average VO concentration of a hazardous waste at the point of
waste treatment and comparing the results to the exit concentration limit
specified for the process used to treat the hazardous waste; the organic
reduction efficiency and the organic biodegradation efficiency for a biological
process used to treat a hazardous waste and comparing the results to the
applicable standards; or the maximum volatile organic vapor pressure for a
hazardous waste in a tank and comparing the results to the applicable
standards. (2) "Waste
stabilization process" means any physical or chemical process used to
either reduce the mobility of hazardous constituents in a hazardous waste or
eliminate free liquids as determined by test method 9095B ("Paint Filter
Liquids Test") in "Test Methods for Evaluating Solid Waste,
Physical/Chemical Methods," U.S. EPA publication SW-846, as incorporated
by reference in rule 3745-50-11 of the Administrative Code. A waste
stabilization process includes mixing the hazardous waste with binders or other
materials, and curing the resulting hazardous waste and binder mixture. Other
synonymous terms used to refer to this process are "waste fixation"
or "waste solidification." This does not include the adding of
absorbent materials to the surface of a waste, without mixing, agitation, or
subsequent curing, to absorb free liquid. [Comment: For dates of non-regulatory government
publications, publications of recognized organizations and associations,

rules 3745-256-80 to 3745-256-90 of the Administrative Code. (B) The owner or operator shall control
air pollutant emissions from each hazardous waste management unit in accordance
with standards specified in rules 3745-256-85 to 3745-256-88 of the
Administrative Code, as applicable to the hazardous waste management unit,
except as provided for in paragraph (C) of this rule. (C) A tank, surface impoundment, or
container is exempt from standards specified in rules 3745-256-85 to
3745-256-88 of the Administrative Code, as applicable, provided that the waste
management unit is one of the following: (1) A tank, surface
impoundment, or container for which all hazardous waste entering the unit has
an average volatile organics (VO) concentration at the point of waste
origination of less than five hundred parts per million by weight (ppmw). The
average VO concentration shall be determined using the procedures specified in
paragraph (A) of rule 3745-256-84 of the Administrative Code. The owner or
operator shall review and update, as necessary, this determination at least
once every twelve months after the date of the initial determination for the
hazardous waste streams entering the unit. (2) A tank, surface
impoundment, or container for which the organic content of all the hazardous

destruction or removal process that achieves any one of the following
conditions: (a) A process that removes or destroys the organics
contained in the hazardous waste to a level such that the average VO
concentration of the hazardous waste at the point of waste treatment is less
than the exit concentration limit (Ct)
established for the process. The average VO concentration of the hazardous
waste at the point of waste treatment and the exit concentration limit for the
process shall be determined using the procedures specified in paragraph (B) of
rule 3745-256-84 of the Administrative Code. (b) A process that removes or destroys the organics

Code, as applicable to the waste management unit. (ii) From the point of
waste origination through the point where the hazardous waste enters the
treatment process, any transfer of the hazardous waste is accomplished through
continuous hard-piping or other closed system transfer that does not allow
exposure of the waste to the atmosphere. Ohio EPA considers a drain system that
meets the requirements of 40 CFR Part 63 subpart RR "National Emission
Standards for Individual Drain Systems" to be a closed
system. (iii) The average VO
concentration of the hazardous waste at the point of waste treatment is less
than the lowest average VO concentration at the point of waste origination

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, or a value of twenty-five ppmw, whichever is less. (ii) 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 also can be expressed as 1.8

tank, surface impoundment, or container, then the director may choose an
appropriate method. (3) In a case when the
owner or operator is requested to perform the waste determination, the director
may elect to have an authorized representative observe the collection of the
hazardous waste samples used for the analysis. (4) In a case when the
results of the waste determination performed or requested by the director do
not agree with the results of a waste determination performed by the owner or
operator using knowledge of the waste, then the results of the waste
determination performed in accordance with the requirements of paragraph (D)(1)
of this rule shall be used to establish compliance with the requirements of
rules 3745-256-80 to 3745-256-90 of the Administrative Code. (5) In a case when the
owner or operator has used an averaging period greater than one hour for
determining the average VO concentration of a hazardous waste at the point of
waste origination, the director may elect to establish compliance with rules
3745-256-80 to 3745-256-90 of the Administrative Code by performing or
requesting that the owner or operator perform a waste determination using
direct measurement based on waste samples collected within a one-hour period as
follows: (a) The average VO concentration of the hazardous waste at
the point of waste origination shall be determined by direct measurement in
accordance with the requirements of paragraph (A) of rule 3745-256-84 of the
Administrative Code. (b) Results of the waste determination performed or
requested by the director showing that the average VO concentration of the
hazardous waste at the point of waste origination is equal to or greater than
five hundred ppmw shall constitute noncompliance with rules 3745-256-80 to
3745-256-90 of the Administrative Code except in a case as provided for in
paragraph (D)(5)(c) of this rule. (c) For the case when the average VO concentration of the
hazardous waste at the point of waste origination previously has been
determined by the owner or operator using an averaging period greater than one
hour to be less than five hundred ppmw but because of normal operating process
variations the VO concentration of the hazardous waste determined by direct
measurement for any given one-hour period may be equal to or greater than five
hundred ppmw, information that was used by the owner or operator to determine
the average VO concentration of the hazardous waste (e.g., test results,
measurements, calculations, and other documentation) and recorded in the
facility records in accordance with the requirements of paragraph (A) of rule
3745-256-84 and rule 3745-256-90 of the Administrative Code shall be considered
by the director together with the results of the waste determination performed
or requested by the director in establishing compliance with rules 3745-256-80
to 3745-256-90 of the Administrative Code. [Comment: For dates of non-regulatory government

Rule 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: (3)(d)(i).jpg) Where:  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) 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 paragraphs (C)(2)(a) to (C)(2)(f) 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 treated waste stream is placed in a waste management unit exempted under paragraph (C)(2), (C)(3), 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) of rule 3745-256-83 of the Administrative Code 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) to (B)(9) of this rule. (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 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 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 (B)(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 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 art 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. 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. (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.

(2) An owner or operator shall use either direct measurement as specified in paragraph (C)(3) of this rule or knowledge of the waste as specified by paragraph (C)(4) of this rule 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"; (iii) Methods obtained from standard reference texts; (iv) ASTM method D2879-10; and (v) Any other method approved by the director. (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 paragraph (B)(1)(a) of rule 3745-256-85 of the Administrative Code 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 rules 3745-256-80 to 3745-256-90 of the Administrative Code: (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 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.

Rule 3745-256-85 | Tanks - air emission standards for tanks, surface impoundments, and containers.
(A) Rules 3745-256-80 to 3745-256-90 of
the Administrative Code apply to the control of air pollutant emissions from
tanks for which paragraph (B) of rule 3745-256-83 of the Administrative Code
references the use of this rule for such air emission control. (B) The owner or operator shall control
air pollutant emissions from each tank subject to this rule in accordance with
the following requirements, as applicable: (1) For a tank that
manages hazardous waste that meets all of the conditions specified in
paragraphs (B)(1)(a) to (B)(1)(c) of this rule, the owner or operator shall
control air pollutant emissions from the tank in accordance with the "Tank
Level 1" controls specified in paragraph (C) of this rule or the
"Tank Level 2" controls specified in paragraph (D) of this
rule. (a) The hazardous waste in the tank has a maximum organic
vapor pressure which is less than the maximum organic vapor pressure limit for
the tank's design capacity category as follows: (i) For a tank design
capacity equal to or greater than one hundred fifty-one m3, the maximum organic vapor pressure limit for
the tank is 5.2 kilopascals (kPa). (ii) For a tank design
capacity equal to or greater than seventy-five m3 but less than one hundred fifty-one
m3, the maximum organic vapor
pressure limit for the tank is 27.6 kPa. (iii) For a tank design
capacity less than seventy-five m3, the maximum organic vapor pressure limit for
the tank is 76.6 kPa. (b) The hazardous waste in the tank is not heated by the
owner or operator to a temperature that is greater than the temperature at
which the maximum organic vapor pressure of the hazardous waste is determined
for the purpose of complying with paragraph (B)(1)(a) of this
rule. (c) The hazardous waste in the tank is not treated by the
owner or operator using a waste stabilization process, as defined in rule
3745-256-81 of the Administrative Code. (2) For a tank that
manages hazardous waste that does not meet all of the conditions specified in
paragraphs (B)(1)(a) to (B)(1)(c) of this rule, the owner or operator shall
control air pollutant emissions from the tank by using "Tank Level 2"
controls in accordance with the requirements of paragraph (D) of this rule.
Examples of tanks required to use "Tank Level 2" controls include a
tank used for a waste stabilization process; and a tank for which the hazardous
waste in the tank has a maximum organic vapor pressure that is equal to or
greater than the maximum organic vapor pressure limit for the tank's
design capacity category as specified in paragraph (B)(1)(a) of this
rule. (C) Owners and operators controlling air
pollutant emissions from a tank using "Tank Level 1" controls shall
meet the requirements specified in paragraphs (C)(1) to (C)(4) of this
rule: (1) The owner or operator
shall determine the maximum organic vapor pressure for a hazardous waste to be
managed in the tank using "Tank Level 1" controls before the first
time the hazardous waste is placed in the tank. The maximum organic vapor
pressure shall be determined using the procedures specified in paragraph (C) of
rule 3745-256-84 of the Administrative Code. Thereafter, the owner or operator
shall perform a new determination whenever changes to the hazardous waste
managed in the tank could potentially cause the maximum organic vapor pressure
to increase to a level that is equal to or greater than the maximum organic
vapor pressure limit for the tank design capacity category specified in
paragraph (B)(1)(a) of this rule, as applicable to the tank. (2) The tank shall be
equipped with a fixed roof designed to meet the following
specifications: (a) The fixed roof and the fixed roof's closure
devices shall be designed to form a continuous barrier over the entire surface
area of the hazardous waste in the tank. The fixed roof may be a separate cover
installed on the tank (e.g., a removable cover mounted on an open-top tank) or
may be an integral part of the tank structural design (e.g., a horizontal
cylindrical tank equipped with a hatch). (b) The fixed roof shall be installed in a manner such that
there are no visible cracks, holes, gaps, or other open spaces between roof
section joints or between the interface of the roof edge and the tank
wall. (c) Each opening in the fixed roof, and any manifold system
associated with the fixed roof, shall be either: (i) Equipped with a
closure device designed to operate such that when the closure device is secured
in the closed position there are no visible cracks, holes, gaps, or other open
spaces in the closure device or between the perimeter of the opening and the
closure device; or (ii) Connected by a
closed-vent system that is vented to a control device. The control device shall
remove or destroy organics in the vent stream, and shall be operating whenever
hazardous waste is managed in the tank, except as provided for in paragraphs
(C)(2)(c)(ii)(a) and (C)(2)(c)(ii)(b) of this rule. (a) During periods it is
necessary to provide access to the tank for performing the activities of
paragraph (C)(2)(c)(ii)(b) of this rule, venting of the vapor headspace
underneath the fixed roof to the control device is not required, opening of
closure devices is allowed, and removal of the fixed roof is allowed. After
completion of the activity, the owner or operator shall promptly secure the
closure device in the closed position or reinstall the cover, as applicable,
and resume operation of the control device. (b) During periods of
routine inspection, maintenance, or other activities needed for normal
operations, and for the removal of accumulated sludge or other residues from
the bottom of the tank. (d) The fixed roof and the fixed roof's closure
devices shall be made of suitable materials that will minimize exposure of the
hazardous waste to the atmosphere, to the extent practical, and will maintain
the integrity of the fixed roof and closure devices throughout the intended
service life of the fixed roof and closure devices. Factors to be considered
when selecting the materials for and designing the fixed roof and closure
devices shall include organic vapor permeability, the effects of any contact
with the hazardous waste or the hazardous waste's vapors managed in the
tank; the effects of outdoor exposure to wind, moisture, and sunlight; and the
operating practices used for the tank on which the fixed roof is
installed. (3) Whenever a hazardous
waste is in the tank, the fixed roof shall be installed with each closure
device secured in the closed position except as follows: (a) Opening of closure devices or removal of the fixed roof
is allowed at the following times: (i) To provide access to
the tank for performing routine inspection, maintenance, or other activities
needed for normal operations. Examples of such activities include those times
when a worker needs to open a port to sample the liquid in the tank, or when a
worker needs to open a hatch to maintain or repair equipment. After completion
of the activity, the owner or operator shall promptly secure the closure device
in the closed position or reinstall the cover, as applicable, to the
tank. (ii) To remove
accumulated sludge or other residues from the bottom of tank. (b) Opening of a spring-loaded pressure-vacuum relief
valve, conservation vent, or similar type of pressure relief device which vents
to the atmosphere is allowed during normal operations for the purpose of
maintaining the tank internal pressure in accordance with the tank design
specifications. The device shall be designed to operate with no detectable
organic emissions when the device is secured in the closed position. The
settings at which the device opens shall be established such that the device
remains in the closed position whenever the tank internal pressure is within
the internal pressure operating range determined by the owner or operator based
on the tank manufacturer recommendations, applicable regulations, fire
protection and prevention codes, standard engineering codes and practices, or
other requirements for the safe handling of flammable, ignitable, explosive,
reactive, or hazardous materials. Examples of normal operating conditions that
may require these devices to open are during those times when the tank internal
pressure exceeds the internal pressure operating range for the tank as a result
of loading operations or diurnal ambient temperature fluctuations. (c) Opening of a safety device, as defined in rule
3745-256-81 of the Administrative Code, is allowed at any time conditions
require doing so to avoid an unsafe condition. (4) The owner or operator
shall inspect the air emission control equipment in accordance with the
following requirements (a) The fixed roof and the fixed roof's closure
devices shall be visually inspected by the owner or operator to check for
defects that could result in air pollutant emissions. Defects include, but are
not limited to, visible cracks, holes, or gaps in the roof sections or between
the roof and the tank wall; broken, cracked, or otherwise damaged seals or
gaskets on closure devices; and broken or missing hatches, access covers, caps,
or other closure devices. (b) The owner or operator shall perform an initial
inspection of the fixed roof and the fixed roof's closure devices on or
before the date that the tank becomes subject to this rule. Thereafter, the
owner or operator shall perform the inspections at least once every year except
under the special conditions provided for in paragraph (L) of this
rule. (c) In the event that a defect is detected, the owner or
operator shall repair the defect in accordance with the requirements of
paragraph (K) of this rule. (d) The owner or operator shall maintain a record of the
inspection in accordance with the requirements specified in paragraph (B) of
rule 3745-256-90 of the Administrative Code. (D) Owners and operators controlling air

shall control air pollutant emissions from each container subject to this rule
in accordance with the following requirements, as applicable to the container,
except when the special provisions for waste stabilization processes specified
in paragraph (B)(2) of this rule apply to the container. (a) For a container having a design capacity greater than
0.1 cubic meters (m3) and less
than or equal to 0.46 m3, the
owner or operator shall control air pollutant emissions from the container in
accordance with the "Container Level 1" standards specified in
paragraph (C) of this rule. (b) For a container having a design capacity greater than
0.46 m3 that is not in light
material service, the owner or operator shall control air pollutant emissions
from the container in accordance with the "Container Level 1"
standards specified in paragraph (C) of this rule. (c) For a container having a design capacity greater than
0.46 m3 that is in light material
service, the owner or operator shall control air pollutant emissions from the
container in accordance with the "Container Level 2" standards
specified in paragraph (D) of this rule. (2) When a container
having a design capacity greater than 0.1 m3 is used for treatment of a hazardous waste by
a waste stabilization process, the owner or operator shall control air
pollutant emissions from the container in accordance with the "Container
Level 3" standards specified in paragraph (E) of this rule at those times
during the waste stabilization process when the hazardous waste in the
container is exposed to the atmosphere. (C) "Container Level 1"
standards. (1) A container using
"Container Level 1" controls is one of the following: (a) A container that meets the applicable U.S. department
of transportation (DOT) regulations on packaging hazardous materials for
transportation as specified in paragraph (F) of this rule. (b) A container equipped with a cover and closure devices
that form a continuous barrier over the container openings such that when the
cover and closure devices are secured in the closed position there are no
visible holes, gaps, or other open spaces into the interior of the container.
The cover may be a separate cover installed on the container (e.g., a lid on a
drum or a suitably secured tarp on a roll-off box) or may be an integral part
of the container structural design (e.g., a "portable tank" or bulk
cargo container equipped with a screw-type cap). (c) An open-top container in which an organic-vapor
suppressing barrier is placed on or over the hazardous waste in the container
such that no hazardous waste is exposed to the atmosphere. One example of such
a barrier is application of a suitable organic-vapor suppressing
foam. (2) A container used to
meet the requirements of paragraph (C)(1)(b) or (C)(1)(c) of this rule shall be
equipped with covers and closure devices, as applicable to the container, that
are composed of suitable materials to minimize exposure of the hazardous waste
to the atmosphere and to maintain the equipment integrity for as long as the
equipment is in service. Factors to be considered in selecting the materials of
construction and designing the cover and closure devices shall include organic
vapor permeability, the effects of contact with the hazardous waste or the
hazardous waste's vapor managed in the container; the effects of outdoor
exposure of the closure device or cover material to wind, moisture, and
sunlight; and the operating practices for which the container is intended to be
used. (3) Whenever a hazardous
waste is in a container using "Container Level 1" controls, the owner
or operator shall install all covers and closure devices for the container, as
applicable to the container, and secure and maintain each closure device in the
closed position except as follows: (a) Opening of a closure device or cover is allowed for the
purpose of adding hazardous waste or other material to the container as
follows: (i) In the case when the
container is filled to the intended final level in one continuous operation,
the owner or operator shall promptly secure the closure devices in the closed
position and install the covers, as applicable to the container, upon
conclusion of the filling operation. (ii) In the case when
discrete quantities or batches of material intermittently are added to the
container over a period of time, the owner or operator shall promptly secure
the closure devices in the closed position and install covers, as applicable to
the container, upon either the container being filled to the intended final
level; the completion of a batch loading after which no additional material
will be added to the container within fifteen minutes; the person performing
the loading operation leaving the immediate vicinity of the container; or the
shutdown of the process generating the material being added to the container,
whichever condition occurs first. (b) Opening of a closure device or cover is allowed for the
purpose of removing hazardous waste from the container as follows: (i) For the purpose of
meeting the requirements of this rule, an "empty container," as
defined in paragraph (B) of rule 3745-51-07 of the Administrative Code, may be
open to the atmosphere at any time (i.e., covers and closure devices are not
required to be secured in the closed position on an empty
container). (ii) In the case when
discrete quantities or batches of material are removed from the container but
the container does not meet the conditions to be an "empty
container," as defined in paragraph (B) of rule 3745-51-07 of the
Administrative Code, the owner or operator shall promptly secure the closure
devices in the closed position and install covers, as applicable to the
container, upon the completion of a batch removal after which no additional
material will be removed from the container within fifteen minutes or the
person performing the unloading operation leaves the immediate vicinity of the
container, whichever condition occurs first. (c) Opening of a closure device or cover is allowed when
access inside the container is needed to perform routine activities other than
transfer of hazardous waste. Examples of such activities include those times
when a worker needs to open a port to measure the depth of or sample the
material in the container, or when a worker needs to open a manhole hatch to
access equipment inside the container. After completion of the activity, the
owner or operator shall promptly secure the closure device in the closed
position or reinstall the cover, as applicable to the container. (d) Opening of a spring-loaded, pressure-vacuum relief
valve, conservation vent, or similar type of pressure relief device which vents
to the atmosphere is allowed during normal operations for the purpose of
maintaining the container internal pressure in accordance with the design
specifications of the container. The device shall be designed to operate with
no detectable organic emissions when the device is secured in the closed
position. The settings at which the device opens shall be established such that
the device remains in the closed position whenever the internal pressure of the
container is within the internal pressure operating range determined by the
owner or operator based on container manufacturer recommendations, applicable
regulations, fire protection and prevention codes, standard engineering codes
and practices, or other requirements for the safe handling of flammable,
ignitable, explosive, reactive, or hazardous materials. Examples of normal
operating conditions that may require these devices to open are during those
times when the internal pressure of the container exceeds the internal pressure
operating range for the container as a result of loading operations or diurnal
ambient temperature fluctuations. (e) Opening of a safety device is allowed at any time
conditions require doing so to avoid an unsafe condition. (4) The owner or operator
of containers using "Container Level 1" controls shall inspect the
containers and the containers' covers and closure devices as
follows: (a) In the case when a hazardous waste already is in the
container at the time the owner or operator first accepts possession of the
container at the facility and the container is not emptied within twenty-four
hours after the container is accepted at the facility (i.e., does not meet the
conditions for an empty container), the owner or operator shall visually
inspect the container and the container's cover and closure devices to
check for visible cracks, holes, gaps, or other open spaces into the interior
of the container when the cover and closure devices are secured in the closed
position. The container visual inspection shall be conducted on or before the
date that the container is accepted at the facility (i.e., the date the
container becomes subject to the standards in rules 3745-256-80 to 3745-256-90
of the Administrative Code). For purposes of this requirement, the date of
acceptance is the date of signature that the facility owner or operator enters
on item 20 of the "Uniform Hazardous Waste Manifest (U.S. EPA forms
8700-22 and 8700-22A)," as required under rule 3745-65-71 of the
Administrative Code. If a defect is detected, the owner or operator shall
repair the defect in accordance with the requirements of paragraph (C)(4)(c) of
this rule. (b) In the case when a container used for managing
hazardous waste remains at the facility for a period of one year or more, the
owner or operator shall visually inspect the container and the container's
cover and closure devices initially and thereafter, at least once every twelve
months, to check for visible cracks, holes, gaps, or other open spaces into the
interior of the container when the cover and closure devices are secured in the
closed position. If a defect is detected, the owner or operator shall repair
the defect in accordance with the requirements of paragraph (C)(4)(c) of this
rule. (c) When a defect is detected for the container, cover, or
closure devices, the owner or operator shall make first efforts at repair of
the defect no later than twenty-four hours after detection, and repair shall be
completed as soon as possible but no later than five calendar days after
detection. If repair of a defect cannot be completed within five calendar days,
then the hazardous waste shall be removed from the container and the container
shall not be used to manage hazardous waste until the defect is
repaired. (5) The owner or operator
shall maintain at the facility a copy of the procedure used to determine that
containers with capacity of 0.46 m3 or greater, which do not meet applicable DOT
regulations as specified in paragraph (F) of this rule, are not managing
hazardous waste in light material service. (D) "Container Level 2"
standards. (1) A container using
"Container Level 2" controls is one of the following: (a) A container that meets the applicable DOT regulations
on packaging hazardous materials for transportation as specified in paragraph
(F) of this rule. (b) A container that operates with, "no detectable

shall be conducted in such a manner as to minimize exposure of the hazardous
waste to the atmosphere, to the extent practical, considering the physical
properties of the hazardous waste and good engineering and safety practices for
handling flammable, ignitable, explosive, reactive or other hazardous
materials. Examples of container loading procedures that Ohio EPA considers to
meet the requirements of this paragraph include a submerged-fill pipe or other
submerged-fill method to load liquids into the container; a vapor-balancing
system or a vapor-recovery system to collect and control the vapors displaced
from the container during filling operations; or a fitted opening in the top of
a container through which the hazardous waste is filled and subsequently
purging the transfer line before removing the transfer line from the container
opening. (3) Whenever a hazardous
waste is in a container using "Container Level 2" controls, the owner
or operator shall install all covers and closure devices for the container, and
secure and maintain each closure device in the closed position except as
follows: (a) Opening of a closure device or cover is allowed for the

Rule 3745-256-101 | Design and operating standards for containment buildings.
Effective:
September 29, 2021
(A) All containment buildings shall
comply with all of the following design standards: (1) The containment
building shall be completely enclosed with a floor, walls, and a roof to
prevent exposure to the elements, (e.g., precipitation, wind, run-on), and to
assure containment of managed wastes. (2) The floor and
containment walls of the unit, including the secondary containment system if
required under paragraph (B) of this rule, shall be designed and constructed of
materials of sufficient strength and thickness to support the materials, the
waste contents, and any personnel and heavy equipment that operate within the
unit, and to prevent failure due to pressure gradients, settlement,
compression, uplift, physical contact with the wastes to which such floors and
walls are exposed, climatic conditions, and the stresses of daily operation,
including the movement of heavy equipment within the unit and contact of such
equipment with containment walls. The unit shall be designed so that the unit
has sufficient structural strength to prevent collapse or other failure. All
surfaces to be in contact with hazardous wastes shall be chemically compatible
with those wastes. Ohio EPA will consider standards established by professional
organizations generally recognized by the industry such as the American
concrete institute (ACI) and the American society of testing materials (ASTM)
in judging the structural integrity requirements of paragraph (A) of this rule.
If appropriate to the nature of the waste management operation to take place in
the unit, an exception to the structural strength requirement may be made for
light-weight doors and windows that meet both of these criteria: (a) The light-weight doors and windows provide an effective
barrier against fugitive dust emissions under paragraph (C)(1)(d) of this
rule. (b) The unit is designed and operated in a fashion that assures
that wastes will not actually come in contact with these openings. (3) Incompatible
hazardous wastes or treatment reagents shall not be placed in the unit or the
unit's secondary containment system if the incompatible hazardous wastes
or treatment reagents could cause the unit or secondary containment system to
leak, corrode, or otherwise fail. (4) A containment
building shall have a primary barrier designed to withstand the movement of
personnel, waste, and handling equipment in the unit during the operating life
of the unit and appropriate for the physical and chemical characteristics of
the waste to be managed. (B) For a containment building used to
manage hazardous wastes that contain free liquids or treated with free liquids
(the presence of which is determined by the paint filter test, a visual
examination, or other appropriate means), the owner or operator shall include
all of the following: (1) A primary barrier
designed and constructed of materials to prevent the migration of hazardous
constituents into the barrier (e.g. a geomembrane covered by a concrete wear
surface). (2) A liquid collection
and removal system to prevent the accumulation of liquid on the primary barrier
of the containment building: (a) The primary barrier shall be sloped to drain liquids to the
associated collection system. (b) Liquids and waste shall be collected and removed to minimize
hydraulic head on the containment system at the earliest practicable time that
protects human health and the environment. (3) A secondary
containment system including a secondary barrier designed and constructed to
prevent migration of hazardous constituents into the barrier, and a leak
detection system that is capable of detecting failure of the primary barrier
and collecting accumulated hazardous wastes and liquids at the earliest
practicable time. (a) The requirements of the leak detection component of the
secondary containment system are satisfied by installation of a system that is,
at a minimum, both: (i) Constructed with a
bottom slope of one per cent or more. (ii) Constructed of a
granular drainage material with a hydraulic conductivity of 1 x 10-2 centimeters per second or more and a
thickness of twelve inches (30.5 centimeters) or more, or constructed of
synthetic or geonet drainage materials with a transmissivity of 3 x
10-5 meters squared per second or
more. (b) If treatment is to be conducted in the building, an area in
which such treatment will be conducted shall be designed to prevent the release
of liquids, wet materials, or liquid aerosols to other portions of the
building. (c) The secondary containment system shall be constructed of
materials that are chemically resistant to the waste and liquids managed in the
containment building and of sufficient strength and thickness to prevent
collapse under the pressure exerted by overlaying materials and by any
equipment used in the containment building. Containment buildings can serve as
secondary containment systems for tanks placed within the building under
certain conditions. A containment building can serve as an external liner
system for a tank, provided the containment building complies with paragraph
(E)(1) of rule 3745-66-93 of the Administrative Code. In addition, the
containment building shall comply with paragraphs (B) and (C) of rule
3745-66-93 of the Administrative Code to be considered an acceptable secondary
containment system for a tank. (4) For existing units
other than ninety-day generator units, the director may delay the secondary
containment requirement for up to two years, based on a demonstration by the
owner or operator that the unit substantially meets the standards of rules
3745-256-100 to 3745-256-102 of the Administrative Code. In making this
demonstration, the owner or operator shall do all of the
following: (a) Provide written notice to the director of the owner's or
operator's request. This notification shall describe the unit and the
unit's operating practices with specific reference to the performance of
existing containment systems, and specific plans for retrofitting the unit with
secondary containment. (b) Respond within thirty days to any comments from the director
on these plans. (c) Fulfill the terms of the revised plans, if such plans are
approved by the director. (C) Owners or operators of all
containment buildings shall do all of the following: (1) Use controls and
practices to ensure containment of the hazardous waste within the unit, and, at
a minimum: (a) Maintain the primary barrier to be free of significant
cracks, gaps, corrosion, or other deterioration that could cause hazardous
waste to be released from the primary barrier. (b) Maintain the level of the stored or treated hazardous waste
within the containment walls of the unit so that the height of any containment
wall is not exceeded. (c) Take measures to prevent the tracking of hazardous waste out
of the unit by personnel or by equipment used in handling the waste. An area
shall be designated to decontaminate equipment and any rinsate shall be
collected and properly managed. (d) Take measures to control fugitive dust emissions such that
any openings (doors, windows, vents, cracks, etc.) exhibit no visible
emissions. In addition, all associated particulate collection devices (e.g.,
fabric filter, electrostatic precipitator) shall be operated and maintained
with sound air pollution control practices. This state of no visible emissions
shall be maintained effectively at all times during normal operating
conditions, including when vehicles and personnel are entering and exiting the
unit. (2) Obtain and keep
on-site a certification by a qualified professional engineer that the
containment building design complies with paragraphs (A) to (C)(4) of this
rule. (3) Throughout the active
life of the containment building, if the owner or operator detects a condition
that could lead to or has caused a release of hazardous waste, the owner or
operator shall repair the condition promptly, in accordance with the following
procedures: (a) Upon detection of a condition that has led to a release of
hazardous waste (e.g., upon detection of leakage from the primary barrier) the
owner or operator shall do all of the following: (i) Enter a record of the
discovery in the facility operating record. (ii) Immediately remove
from service the portion of the containment building affected by the
condition. (iii) Determine what
steps shall be taken to repair the containment building, remove any leakage
from the secondary collection system, and establish a schedule for
accomplishing the cleanup and repairs. (iv) Within seven days
after the discovery of the condition, notify the director of the condition, and
within fourteen working days, provide a written plan to the director with a
description of the steps taken to repair the containment building, and the
schedule for accomplishing the work. (b) The director will review the information submitted, make a
determination regarding whether the containment building shall be completely or
partially removed from service until repairs and cleanup are complete, and
notify the owner or operator in writing of the determination and the underlying
rationale. (c) Upon completing all repairs and cleanup, the owner or
operator shall notify the director in writing and provide a verification,
signed by a qualified, registered professional engineer, that the repairs and
cleanup were completed according to the written plan submitted in accordance
with paragraph (C)(3)(a)(iv) of this rule. (4) At least once every
seven days, inspect and record in the facility's operating record data
gathered from monitoring equipment, leak detection equipment, the containment
building, and the area that immediately surrounding the containment building,
to detect signs of releases of hazardous waste. (D) For a containment building that
contains both areas with and without secondary containment, the owner or
operator shall do all of the following: (1) Design and operate
each area in accordance with paragraphs (A) to (C)(4) of this
rule. (2) Take measures to
prevent the release of liquids or wet materials into areas without secondary
containment. (3) Maintain in the
facility's operating record a written description of the operating
procedures used to maintain the integrity of areas without secondary
containment. (E) Notwithstanding any other provision
of rules 3745-256-100 to 3745-256-102 of the Administrative Code, the director
may waive requirements for secondary containment for a permitted containment
building where the owner or operator demonstrates that the only free liquids in
the unit are limited amounts of dust suppression liquids required to meet
occupational health and safety requirements, and where containment of managed
wastes and liquids can be assured without a secondary containment
system.

Rule 3745-256-102 | Closure and post-closure care of containment buildings.
Effective:
December 7, 2004
(A) At closure of a containment building, the owner or operator must remove or decontaminate all waste residues, contaminated containment system components (liners, etc.), contaminated subsoils, and structures and equipment contaminated with waste and leachate, and manage them as hazardous waste unless paragraph (D) of rule 3745-51-03 of the Administrative Code applies. The closure plan, closure activities, cost estimates for closure, and financial responsibility for containment buildings must meet all of the requirements specified in rules 3745-66-10 to 3745-66-21 and 3745-66-40 to 3745-66-48 of the Administrative Code. (B) If, after removing or decontaminating all residues and making all reasonable efforts to effect removal or decontamination of contaminated components, subsoils, structures, and equipment as required in paragraph (A) of this rule, the owner or operator finds that not all contaminated subsoils can be practicably removed or decontaminated, he must close the facility and perform post-closure care in accordance with the closure and post-closure requirements that apply to landfills (rule 3745-68-10 of the Administrative Code). In addition, for the purposes of closure, post-closure, and financial responsibility, such a containment building is then considered to be a landfill and the owner or operator must meet all of the requirements for landfills specified in rules 3745-66-10 to 3745-66-21 and 3745-66-40 to 3745-66-48 of the Administrative Code.

Rule 3745-256-200 | Applicability- military munitions.
Rules 3745-256-200 to 3745-256-202 of the
Administrative Code apply to owners or operators who store hazardous waste
munitions and hazardous waste explosives, except as rule 3745-65-01 of the
Administrative Code provides otherwise. [Comment: Depending on explosive hazards, hazardous
waste munitions and hazardous waste explosives may also be managed in other
types of storage units, including containment buildings (rules 3745-256-100 to
3745-256-102 of the Administrative Code), tanks (rules 3745-66-90 to
3745-66-102 of the Administrative Code), or containers (rules 3745-66-70 to
3745-66-78 of the Administrative Code). See rule 3745-266-205 of the
Administrative Code for storage of waste military munitions.]

Rule 3745-256-201 | Design and operating standards for military munitions.
Effective:
September 5, 2010
(A) Hazardous waste munitions and hazardous waste explosives storage units must be designed and operated with containment systems, controls, and monitoring, that: (1) Minimize the potential for detonation or other means of release of hazardous waste, hazardous constituents, hazardous decomposition products, or contaminated run-off, to the soil, ground water, surface water, and atmosphere; (2) Provide a primary barrier, which may be a container (including a shell) or tank, designed to contain the hazardous waste; (3) For wastes stored outdoors, provide that the waste and containers will not be in standing precipitation; (4) For liquid wastes, provide a secondary containment system that assures that any released liquids are contained and promptly detected and removed from the waste area, or vapor detection system that assures that any released liquids or vapors are promptly detected and an appropriate response taken (e.g., additional containment, such as overpacking, or removal from the waste area); and (5) Provide monitoring and inspection procedures that assure the controls and containment systems are working as designed and that releases that may adversely impact human health or the environment are not escaping from the unit. (B) Hazardous waste munitions and hazardous waste explosives stored under rules 3745-256-200 to 3745-256-202 of the Administrative Code may be stored in one of the following: (1) Earth-covered magazines. Earth-covered magazines must be: (a) Constructed of waterproofed, reinforced concrete or structural steel arches, with steel doors that are kept closed when not being accessed; (b) Designed and constructed: (i) To be of sufficient strength and thickness to support the weight of any explosives or munitions stored and any equipment used in the unit; (ii) To provide working space for personnel and equipment in the unit; and (iii) To withstand movement activities that occur in the unit; and (c) Located and designed, with walls and earthen covers that direct an explosion in the unit in a safe direction, so as to minimize the propagation of an explosion to adjacent units and to minimize other effects of any explosion. (2) Above-ground magazines. Above-ground magazines must be located and designed so as to minimize the propagation of an explosion to adjacent units and to minimize other effects of any explosion. (3) Outdoor or open storage areas. Outdoor or open storage areas must be located and designed so as to minimize the propagation of an explosion to adjacent units and to minimize other effects of any explosion. (C) Hazardous waste munitions and hazardous waste explosives must be stored in accordance with a standard operating procedure specifying procedures to ensure safety, security, and environmental protection. If these procedures serve the same purpose as the security and inspection requirements of rule 3745-65-14 of the Administrative Code, the preparedness and prevention procedures of rules 3745-65-30 to 3745-65-37 of the Administrative Code, and the contingency plan and emergency procedures requirements of rules 3745-65-50 to 3745-65-56 of the Administrative Code, then these procedures will be used to fulfill those requirements. (D) Hazardous waste munitions and hazardous waste explosives must be packaged to ensure safety in handling and storage. (E) Hazardous waste munitions and hazardous waste explosives must be inventoried at least annually. (F) Hazardous waste munitions and hazardous waste explosives and their storage units must be inspected and monitored as necessary to ensure explosives safety and to ensure that there is no migration of contaminants out of the unit.

Rule 3745-256-202 | Closure and post-closure care of military munitions.
Effective:
December 7, 2004
(A) At closure of a magazine or unit which stored hazardous waste under rules 3745-256-200 to 3745-256-202 of the Administrative Code, the owner or operator must remove or decontaminate all waste residues, contaminated containment system components, contaminated subsoils, and structures and equipment contaminated with waste, and manage them as hazardous waste unless paragraph (D) of rule 3745-51-03 of the Administrative Code applies. The closure plan, closure activities, cost estimates for closure, and financial responsibility for magazines or units must meet all of the requirements specified in rules 3745-66-10 to 3745-66-21 and 3745-66-40 to 3745-66-48 of the Administrative Code, except that the owner or operator may defer closure of the unit as long as it remains in service as a munitions or explosives magazine or storage unit. (B) If, after removing or decontaminating all residues and making all reasonable efforts to effect removal or decontamination of contaminated components, subsoils, structures, and equipment as required in paragraph (A) of this rule, the owner or operator finds that not all contaminated subsoils can be practicably removed or decontaminated, he must close the facility and perform post-closure care in accordance with the closure and post-closure requirements that apply to landfills (see rule 3745-68-10 of the Administrative Code).
