(2) 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 it 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).
(3) 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.
(4) 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.
(5) 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.
(6) 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.
(7) 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.
(8) 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.
(9) 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.
(10) Hard-piping means pipe or tubing that is manufactured and properly installed in accordance with relevant standards and good engineering practices.
(11) In light material service means the container is used to manage a material for which both of the following conditions apply: The vapor pressure of one or more of the organic constituents in the material is greater than 0.3 kilopascals (kPa) at 20 degrees C; and the total concentration of the pure organic constituents having a vapor pressure greater than 0.3 kPa at 20 degrees C is equal to or greater than 20 percent by weight.
(12) Internal floating roof means a cover that rests or floats on the material surface (but not necessarily in complete contact with it) inside a tank that has a fixed roof.
(13) 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.
(14) 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.
(15) 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 this section, maximum organic vapor pressure is determined using the procedures specified in paragraph (e)(3) of this section.
(16) 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.
(17) No detectable organic emissions means no escape of organics to the atmosphere as determined using the procedure specified in paragraph (e)(4) of this section.
(18) Point of waste origination means as follows:
(i) When the facility owner or operator is the generator of the hazardous waste, the point of waste origination means the point where a solid waste produced by a system, process, or waste management unit is determined to be a hazardous waste as defined in Part 371 of this Title.
Note: 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 parts 60, 61, and 63 (incorporated by reference in section 370.1 [e] of this Title).
(ii) 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.
(19) Point of waste treatment means the point where a hazardous waste to be treated in accordance with subparagraph (d)(3)(ii) of this section 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.
(20) 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 its 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 this section, 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.
(21) Single-seal system means a floating roof having one continuous seal. This seal may be vapor-mounted, liquid-mounted, or a metallic shoe seal.
(22) 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.
(23) 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 subdivision (e) of this section. For the purpose of determining 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 can also be expressed as 1.8 x 10[-6] atmospheres/gram-mole/m[3] at 25 degrees Celsius must be included. A list of compounds known to have a Henry's Law constant value less than the cutoff level can be found at appendix VI to 40 CFR part 265 as incorporated by reference in Appendix 55 of this Title.
EXPLANATION: Matter in braces [] is superscript material.
(24) Waste determination means performing all applicable procedures in accordance with the requirements of subdivision (e) of this section to determine whether a hazardous waste meets standards specified in this section. Examples of a waste determination include performing the procedures in accordance with the requirements of subdivision (e) of this section 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.
(25) 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 9095 (Paint Filter Liquids Test) in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication No. SW-846, as incorporated by reference in section 370.1(e) of this Title. 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.

Samples of the hazardous waste stream shall be collected at the point of waste origination in 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.
(1) 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.
(2) 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.
(3) 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 an acceptable sampling plan includes a plan incorporating sample collection and handling procedures in accordance with the requirements specified in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication SW-846, as incorporated by reference in section 370.1(e) of this Title, or in Method 25D in 40 CFR part 60, appendix A as incorporated by reference in section 370.1(e) of this Title.
(4) Sufficient information, as specified in the "site-sampling plan" required under subclause (1)(iii)(b)(3) of this subdivision, 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 one or more of the methods listed in subclause 373-3.29(e)(1)(iii)(c)(1) through 373-3.29(e)(1)(iii)(c)(9) of this subdivision, including appropriate quality assurance and quality control (QA/QC) checks and use of target compounds for calibration. If method 25D in 40 CFR part 60, appendix A as incorporated by reference in subdivision 370.1(e) of this Title, is not used, then one or more methods should be chosen that are appropriate to ensure that the waste determination 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 (0.1y/x) (which can also be expressed as 1.8 x 10[-6] atmospheres/gram-mole/m[3]) at 25 degrees Celsius. Each of the analytical methods listed in subclause 373-3.29(e)(1)(iii)(c)(2) through 373-3.29(e)(1)(iii)(c)(7) of this subdivision has an associated list of approved chemical compounds, for which the Department considers the methods appropriate for measurement. If an owner or operator uses EPA Method 624, 625, 1624, or 1625 in 40 CFR Part 136 Appendix A, as incorporated by reference in subdivision 370.1(e) of this Title, to analyze one or more compounds that are not on that method's published list, the Alternative Test Procedure contained in 40 CFR Part 136.4 and 136.5, as incorporated by reference in subdivision 370.1(e), must be followed. If an owner or operator uses EPA Method 8260 or 8270 in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", EPA publication SW-846, (as incorporated by reference in subdivision 370.1(e) of this Title) to analyze one or more compounds that are not on that method's published list, the procedures in subclause (1)(iii)(c)(8) of this subdivision must be followed. At the owner's or operator's discretion, the owner or operator may adjust test data measured by a method other than Method 25D 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, as incorporated by reference in subdivision 370.1(e) of this Title. To adjust these data, the measured concentration of each individual chemical constituent contained in the waste is multiplied by the appropriate constituent-specific adjustment factor (fm25D). If the owner or operator elects to adjust test data, the adjustment must be made to all individual chemical constituents with a Henry's law constant value greater than or equal to 0.1Y/X at 25 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.

Where:
*C = Average VO concentration of the hazardous waste at the point of waste origination on a mass-weighted basis, ppmw.
i = Individual waste determination "i" of the hazardous waste.
n = Total number of waste determinations of the hazardous waste conducted for the averaging period (not to exceed 1 year). Q[i] = Mass quantity of hazardous waste stream represented by C[i], kg/hr. Q[T] = Total mass quantity of hazardous waste during the averaging period, kg/hr.
C[i] = Measured VO concentration of waste determination "i" as determined in accordance with the requirements of clause 373-3.29(e)(1)(iii)(c) of this subdivision, (i.e., the average of the four or more samples specified in subclause 373-3.29(e)(1)(iii)(b)(2) of this subdivision), ppmw. * Note: The letter C in this equation should be shown with a line above the C.
(2) For the purpose of determining C[i], for individual waste samples analyzed in accordance with clause 373-3.29(e)(1)(iii)(c) of this subdivision, 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:

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 (f[m25D]). EXPLANATION--Mater in brackets [] is subscript material.
(d) In the event that the commissioner 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 subparagraph (1)(iii) of this subdivision shall be used to establish compliance with the applicable requirements of this section. The commissioner 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 clause 373-3.29(e)(1)(iii)(c) of this subdivision.
(2) Waste determination procedures for treated hazardous waste.
(i) An owner or operator shall perform the applicable waste determination for each treated hazardous waste placed in a waste management unit exempted under the provisions of clauses 373-3.29(d)(3)(ii)(a) through 373-3.29(d)(3)(ii)(f) of this section from using air emission controls in accordance with standards specified in subdivisions 373-3.29(f) through 373-3.29(i) of this section, as applicable to the waste management unit.
(a) An initial determination of the average VO concentration of the waste stream shall be made before the first time any portion of the material in the treated waste stream is placed in a waste management unit exempted under the provisions of subparagraphs 373-3.29(d)(3)(ii), 373-3.29(d)(3)(iii), or 373-3.29(d)(3)(iv) of this section from using air emission controls, and thereafter update the information used for the waste determination at least once every 12 months following the date of the initial waste determination; 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 subparagraphs 373-3.29(d)(3)(ii), 373-3.29(d)(3)(iii), or 373-3.29(d)(3)(iv) of this section are not achieved.

(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.
(1) The averaging period to be used for determining 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.
(2) 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.

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.

(c) Analysis. Each collected sample shall be prepared and analyzed in accordance with one or more of the methods listed in subclauses (2)(iii)(c)(1) through (2)(iii)(c)(9) of this subdivision, including appropriate quality assurance and quality control (QA/QC) checks and use of target compounds for calibration. 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 clauses 373-2.29(c)(3)(ii)(a) through (3)(ii)(f) of this Part, or 373-3.29(d)(3)(ii)(a) through (3)(ii)(f) of this section 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. If Method 25D in 40 CFR part 60, appendix A, as incorporated by reference in subdivision 370.1(e) of this Title, is not used, then one or more of the methods should be chosen that are appropriate to ensure that the waste determination 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 (0.1Y/X) (which can also be expressed as 1.8 x 10[-6] atmospheres/gram-mole/m[3]) at 25 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 (f[m25D]). If the owner or operator elects to adjust test data, the adjustment must be made to all individual chemical constituents with a Henry's law constant equal to or greater than 0.1Y/X at 25 degrees Celsius contained in the 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 an acceptable sampling plan includes a plan incorporating sample collection and handling procedures in accordance with the requirements specified in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication No. SW-846, (as incorporated by reference in section 370.1 (e) of this Title), or in Method 25D in 40 CFR part 60, appendix A, as incorporated by reference in section 370.1(e) of this Title.

(1) Method 25E in 40 CFR part 60 appendix A, as incorporated by reference in section 370.1(e) of this Title;
(2) methods described in American Petroleum Institute Publication 2517, Third Edition, February 1989, "Evaporative Loss from External Floating-Roof Tanks," as incorporated by reference in section 370.1(e) of this Title;
(3) methods obtained from standard reference texts;
(4) ASTM Method 2879-92, as incorporated by reference in section 370.1(e) of this Title; and
(5) any other method approved by the commissioner.
(iv) 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 clause (f)(2)(i)(a) of this section 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.
(4) Procedure for determining no detectable organic emissions for the purpose of complying with this section:
(i) The test shall be conducted in accordance with the procedures specified in Method 21 of 40 CFR part 60, appendix A, as incorporated by reference in section 370.1(e) of this Title. Each potential leak interface (i.e., a location where organic vapor leakage could occur) on the cover and associated closure devices shall be checked. Potential leak interfaces that are associated with covers and closure devices include, but are not limited to: the interface of the cover and its foundation mounting; the periphery of any opening on the cover and its associated closure device; and the sealing seat interface on a spring-loaded pressure relief valve.
(ii) 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.
(iii) The detection instrument shall meet the performance criteria of Method 21 of 40 CFR part 60, appendix A, as incorporated by reference in section 370.1(e) of this Title, 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.
(iv) The detection instrument shall be calibrated before use on each day of its use by the procedures specified in Method 21 of 40 CFR part 60, appendix A, as incorporated by reference in section 370.1(e) of this Title.
(v) Calibration gases shall be as follows:
(a) zero air (less than 10 ppmv hydrocarbon in air); and
(b) a mixture of methane or n-hexane and air at a concentration of approximately, but less than 10,000 ppmv methane or n-hexane.
(vi) The background level shall be determined according to the procedures in Method 21 of 40 CFR part 60, appendix A, as incorporated by reference in section 370.1(e) of this Title.
(vii) 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, as incorporated by reference in section 370.1(e) of this Title. 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.
(viii) The arithmetic difference between the maximum organic concentration indicated by the instrument and the background level shall be compared with the value of 500 ppmv except when monitoring a seal around a rotating shaft that passes through a cover opening, in which case the comparison shall be as specified in subparagraph (ix) of this paragraph. If the difference is less than 500 ppmv, then the potential leak interface is determined to operate with no detectable organic emissions.
(ix) For the seals around a rotating shaft that passes through a cover opening, the arithmetic difference between the maximum organic concentration indicated by the instrument and the background level shall be compared with the value of 10,000 ppmw. If the difference is less than 10,000 ppmw, then the potential leak interface is determined to operate with no detectable organic emissions.

(ii) Transfer of hazardous waste in or out of a container using Container Level 2 controls 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 the department considers to meet the requirements of this paragraph include using any one of the following: 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 it from the container opening.
(iii) 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 purpose of adding hazardous waste or other material to the container as follows:
(1) 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.
(2) 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 15 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:
(1) For the purpose of meeting the requirements of this subdivision, an empty container as defined in section 371.1 (h)(2) of this Title, 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).
(2) 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 section 371.1(h)(2) of this Title, 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 15 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. Following
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 internal pressure of the container in accordance with
the container design specifications. The device shall be designed to
operate with no detectable organic emission 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, as defined in subdivision (b) of this section, is allowed at any time conditions require doing so to avoid an
unsafe condition.
(iv) The owner or operator of containers using Container Level 2 controls shall inspect the containers and their 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 (i.e., does not meet
the conditions for an empty container as specified in paragraph
371.1(h)(2) of this Title) within 24 hours after the container arrives
at the facility, the owner or operator shall visually inspect the container and its 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 subdivision 373-3.29(h) of this section). 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 in Appendix 30 of Part 372 of this Title, as required under section 373-3.5 of this Subpart, at paragraph 373-3.5(b)(1). If a defect is detected, the owner or operator shall repair the defect in accordance with the requirements of clause

units with covers that are designated as "unsafe to inspect and monitor," the explanation for each cover stating why the cover is unsafe to inspect and monitor, and the plan and schedule for inspecting and
monitoring each cover.
(8) The owner or operator of a facility that is subject to this section and to the control device standards in 40 CFR part 60, subpart
VV, or 40 CFR part 61, subpart V, as incorporated by reference in
section 370. 1(e)(2) of this Title, may elect to demonstrate compliance with the applicable subdivisions of this section by documentation either pursuant to this section, or pursuant to the provisions of 40 CFR part
60, subpart VV, or 40 CFR part 61, subpart V, as incorporated by
reference in section 370.1 (e)(2) of this Title, to the extent that the
documentation required by 40 CFR part 60 or 61 duplicates the
documentation required by this subdivision.
(9) For each tank or container not using air emission controls specified in subdivisions (f) through (i) of this section in accordance
with the conditions specified in paragraph (a)(4) of this section, the
owner or operator shall record and maintain the following information:
(i) a list of the individual organic peroxide compounds manufactured at the facility that meet the conditions specified in subparagraph
(a)(4)(i) of this section;
(ii) a description of how the hazardous waste containing the organic peroxide compounds identified in subparagraph (i) of this paragraph are
managed at the facility in tanks and containers. This description shall
include the following information:
(a) for the tanks used at the facility to manage this hazardous waste, sufficient information shall be provided to describe for each tank: a
facility identification number for the tank; the purpose and placement
of this tank in the management train of this hazardous waste; and the
procedures used to ultimately dispose of the hazardous waste managed in
the tanks;
(b) for containers used at the facility to manage these hazardous wastes, sufficient information shall be provided to describe: a facility identification number for the container or group of containers; the
purpose and placement of this container, or group of containers, in the
management train of this hazardous waste; and the procedures used to
ultimately dispose of the hazardous waste handled in the containers; and
(iii) an explanation of why managing the hazardous waste containing the organic peroxide compounds identified in subparagraph (i) of this
paragraph in the tanks and containers as described in subparagraph (ii)
of this paragraph would create an undue safety hazard if the air
emission controls, as required under subdivisions (f) through (i) of
this section, are installed and operated on these waste management
units. This explanation shall include the following information:
(a) For tanks used at the facility to manage these hazardous wastes, sufficient information shall be provided to explain: how use of the required air emission controls on the tanks would affect the tank design features and facility operating procedures currently used to prevent an undue safety hazard during the management of this hazardous waste in the tanks; and why installation of safety devices on the required air emission controls, as allowed under this section, will not address those situations in which evacuation of tanks equipped with these air emission controls is necessary and consistent with good engineering and safety
practices for handling organic peroxides.
(b) For containers used at the facility to manage these hazardous wastes, sufficient information shall be provided to explain: how use of
the required air emission controls on the containers would affect the
container design features and handling procedures currently used to
prevent an undue safety hazard during the management of this hazardous
waste in the containers; and why installation of safety devices on the
required air emission controls, as allowed under this section, will not address those situations in which evacuation of containers equipped with these air emission controls is necessary and consistent with good
engineering and safety practices for handling organic peroxides.
(10) For each hazardous waste management unit not using air emission controls specified in 373-3.29(f) through 373-3.29(i) of this section in accordance with the provisions of subparagraph 373-3.29(a)(2)(vii) of
this section, the owner or operator shall record and maintain the
following information:
(i) Certification that the waste management unit is equipped with and operating air emission controls in accordance with the requirements of
an applicable Clean Air Act regulation codified under 40 CFR part 60,
part 61, or part 63, as incorporated by reference in subdivision
370.1(e) of this Title.
(ii) Identification of the specific requirements codified under 40 CFR part 60, part 61, or part 63, as incorporated by reference in subdivision 370.1(e) of this Title, with which the waste management unit is in compliance.
