Current through Register Vol. 48, No. 6, June 28, 2024
(a)
				  This section applies to the management of hazardous waste in tanks, surface
				  impoundments, and containers subject to this subpart.
(b) The owner or operator shall control air
				  pollutant emissions from each hazardous waste management unit in accordance
				  with standards specified in 264.1084 through 264.1087 of this subpart, as
				  applicable to the hazardous waste management unit, except as provided for in
				  paragraph (c) of this section.
(c)
				  A tank, surface impoundment, or container is exempt from standards specified in
				  264.1084 through 264.1087 of this subpart, 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 VO concentration
				  at the point of waste origination of less than 500 parts per million by weight
				  (ppmw). The average VO concentration shall be determined using the procedures
				  specified in 264.1083(a) of this subpart. The owner or operator shall review
				  and update, as necessary, this determination at least once every 12 months
				  following 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 waste entering the waste management unit has been reduced by an
				  organic destruction or removal process that achieves any one of the following
				  conditions:
(i) 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 264.1083(b) of
				  this subpart.
(ii) A process that
				  removes or destroys the organics contained in the hazardous waste to a level
				  such that the organic reduction efficiency (R) for the process is equal to or
				  greater than 95 percent, and the average VO concentration of the hazardous
				  waste at the point of waste treatment is less than 100 ppmw. The organic
				  reduction efficiency for the process and the average VO concentration of the
				  hazardous waste at the point of waste treatment shall be determined using the
				  procedures specified in 264.1083(b) of this subpart.
(iii) A process that removes or destroys the
				  organics contained in the hazardous waste to a level such that the actual
				  organic mass removal rate (MR) for the process is equal to or greater than the
				  required organic mass removal rate (RMR) established for the process. The
				  required organic mass removal rate and the actual organic mass removal rate for
				  the process shall be determined using the procedures specified in 264.1083(b)
				  of this subpart.
(iv) A biological
				  process that destroys or degrades the organics contained in the hazardous
				  waste, such that either of the following conditions is met:
(A) The organic reduction efficiency (R) for
				  the process is equal to or greater than 95 percent, and the organic
				  biodegradation efficiency (Rbio) for the process is
				  equal to or greater than 95 percent. The organic reduction efficiency and the
				  organic biodegradation efficiency for the process shall be determined using the
				  procedures specified in 264.1083(b) of this subpart.
(B) The total actual organic mass
				  biodegradation rate (MRbio) for all hazardous waste
				  treated by the process is equal to or greater than the required organic mass
				  removal rate (RMR). The required organic mass removal rate and the actual
				  organic mass biodegradation rate for the process shall be determined using the
				  procedures specified in 264.1083(b) of this subpart.
(v) A process that removes or destroys the
				  organics contained in the hazardous waste and meets all of the following
				  conditions:
(A) From the point of waste
				  origination through the point where the hazardous waste enters the treatment
				  process, the hazardous waste is managed continuously in waste management units
				  which use air emission controls in accordance with the standards specified in
				  264.1084 through 264.1087 of this subpart, as applicable to the waste
				  management unit.
(B) 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. The 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.
(C) 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 determined for each of the
				  individual waste streams entering the process or 500 ppmw, whichever value is
				  lower. The average VO concentration of each individual waste stream at the
				  point of waste origination shall be determined using the procedures specified
				  in 264.1083(a) of this subpart. The average VO concentration of the hazardous
				  waste at the point of waste treatment shall be determined using the procedures
				  specified in 264.1083(b) of this subpart.
(vi) A process that removes or destroys the
				  organics contained in the hazardous waste to a level such that the organic
				  reduction efficiency (R) for the process is equal to or greater than 95 percent
				  and the owner or operator certifies that the average VO concentration at the
				  point of waste origination for each of the individual waste streams entering
				  the process is less than 10,000 ppmw. The organic reduction efficiency for the
				  process and the average VO concentration of the hazardous waste at the point of
				  waste origination shall be determined using the procedures specified in
				  264.1083(b) and 264.1083(a) of this subpart, respectively.
(vii) A hazardous waste incinerator for which
				  the owner or operator has either:
(A) Been
				  issued a final permit under part 270 which implements the requirements of
				  subpart O of this part; or
(B) Has
				  designed and operates the incinerator in accordance with the interim status
				  requirements of part 265, subpart O.
(viii) A boiler or industrial furnace for
				  which the owner or operator has either:
(A)
				  Been issued a final permit under part 270 which implements the requirements of
				  part 266, subpart H, or
(B) Has
				  designed and operates the boiler or industrial furnace in accordance with the
				  interim status requirements of part 266, subpart H.
(ix) For the purpose of determining the
				  performance of an organic destruction or removal process in accordance with the
				  conditions in each of paragraphs (c)(2)(i) through (c)(2)(vi) of this section,
				  the owner or operator shall account for VO concentrations determined to be
				  below the limit of detection of the analytical method by using the following VO
				  concentration:
(A) If Method 25D in 40 CFR
				  part 60, appendix A is used for the analysis, one-half the blank value
				  determined in the method at section4.4 of Method 25D in 40 CFR part 60,
				  appendix A, or a value of 25 ppmw, whichever is less.
(B) If any other analytical method is used,
				  one-half the sum of the limits of detection established for each organic
				  constituent in the waste that has a Henry's law constant value at least 0.1
				  mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X)
				  [which can also be expressed as 1.8 x 10-6
				  atmospheres/gram-mole/m3] at 25 degrees
				  Celsius.
(3)
				  A tank or surface impoundment used for biological treatment of hazardous waste
				  in accordance with the requirements of paragraph (c)(2)(iv) of this
				  section.
(4) A tank, surface
				  impoundment, or container for which all hazardous waste placed in the unit
				  either:
(i) Meets the numerical concentration
				  limits for organic hazardous constituents, applicable to the hazardous waste,
				  as specified in part 268--Land Disposal Restrictions under Table "Treatment
				  Standards for Hazardous Waste" in 268.40; or
(ii) The organic hazardous constituents in
				  the waste have been treated by the treatment technology established by the EPA
				  for the waste in 268.42(a), or have been removed or destroyed by an equivalent
				  method of treatment approved by EPA pursuant to 268.42(b).
(5) A tank used for bulk feed of hazardous
				  waste to a waste incinerator and all of the following conditions are met:
(i) The tank is located inside an enclosure
				  vented to a control device that is designed and operated in accordance with all
				  applicable requirements specified under 40 CFR part 61, subpart FF--National
				  Emission Standards for Benzene Waste Operations for a facility at which the
				  total annual benzene quantity from the facility waste is equal to or greater
				  than 10 megagrams per year;
(ii)
				  The enclosure and control device serving the tank were installed and began
				  operation prior to November 25, 1996 and
(iii) The enclosure is designed and operated
				  in accordance with the criteria for a permanent total enclosure as specified in
				  "Procedure T--Criteria for and Verification of a Permanent or Temporary Total
				  Enclosure" under
				  40
				  CFR 52.741, appendix B. The enclosure may
				  have permanent or temporary openings to allow worker access; passage of
				  material into or out of the enclosure by conveyor, vehicles, or other
				  mechanical or electrical equipment; or to direct air flow into the enclosure.
				  The owner or operator shall perform the verification procedure for the
				  enclosure as specified in Section5.0 to "Procedure T--Criteria for and
				  Verification of a Permanent or Temporary Total Enclosure" annually.
