(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.
(d) The Department may at any time perform or request that the owner or operator perform a waste determination for a hazardous waste managed in a tank, surface impoundment, or container exempted from using air emission controls under the provisions of this section as follows:
(1) The waste
determination for average VO concentration of a hazardous waste at the point of
waste origination shall be performed using direct measurement in accordance
with the applicable requirements of 264.1083(a) of this subpart. The waste
determination for a hazardous waste at the point of waste treatment shall be
performed in accordance with the applicable requirements of 264.1083(b) of this
subpart.
(2) In performing a waste
determination pursuant to paragraph (d)(1) of this section, the sample
preparation and analysis shall be conducted as follows:
(i) In accordance with the method used by the
owner or operator to perform the waste analysis, except in the case specified
in paragraph (d)(2)(ii) of this section.
(ii) If the Department determines that the
method used by the owner or operator was not appropriate for the hazardous
waste managed in the tank, surface impoundment, or container, then the
Department may choose an appropriate method.
(3) In a case when the owner or operator is
requested to perform the waste determination, the Department 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 Department 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 section shall be used to establish compliance with the
requirements of this subpart.
(5)
In a case when the owner or operator has used an averaging period greater than
1 hour for determining the average VO concentration of a hazardous waste at the
point of waste origination, the Department may elect to establish compliance
with this subpart by performing or requesting that the owner or operator
perform a waste determination using direct measurement based on waste samples
collected within a 1-hour period as follows:
(i) 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 264.1083(a) of this
subpart.
(ii) Results of the waste
determination performed or requested by the Department showing that the average
VO concentration of the hazardous waste at the point of waste origination is
equal to or greater than 500 ppmw shall constitute noncompliance with this
subpart except in a case as provided for in paragraph (d)(5)(iii) of this
section.
(iii) 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 1 hour to be less than 500 ppmw but because of
normal operating process variations the VO concentration of the hazardous waste
determined by direct measurement for any given 1-hour period may be equal to or
greater than 500 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 264.1083(a) and
264.1089 of this subpart shall be considered by the Department together with
the results of the waste determination performed or requested by the Department
in establishing compliance with this subpart.
