                                1.  INTRODUCTION
    Congress recognized that it would be impossible for EPA and authorized states to
    issue permits to all hazardous waste management facilities before the Resource
    Conservation' and Recovery Act (RCRA) Subtitle C program became effective in
    November 1980. RCRA §3005(e) provides for certain facilities to be treated as though
    they had been issued a. permit  until final administrative action is taken on their
    permit applications.  This statutory permit is referred to as "interim status."  EPA
    promulgated interim status management standards in 40 CFR Part  265.

    Part 265 contains both general facility standards applicable to all facilities and
    requirements for specific hazardous waste management units and  treatment
    processes.  EPA initially promulgated interim status standards for the most common
    hazardous waste management units in existence at the inception of the RCRA
    program: containers, tanks, surface impoundments, waste piles, land treatment
    units, landfills, and incinerators (Part 265, Subparts I through O, respectively).  EPA
    realized, however, that certain hazardous waste treatment and disposal practices
    were being conducted in other types of units. As a result, the Agency also
    promulgated interim status standards for broadly defined treatment processes that
    are not performed in any of the previously listed units.  These treatment processes
    include  thermal  treatment (Subpart P); chemical, physical  and biological treatment
    (Subpart Q); and underground  injection (Subpart R).

    EPA promulgated final permit standards in Part 264 for all the specific hazardous
    waste management units originally set forth  in Part 265, Subparts I  through O, as
    well as finalizing both interim status and permit standards for boilers and industrial
    furnaces (BIFs), drip pads, and  containment  buildings.  The Agency, however, never
    established final permit standards for thermal treatment units in Subpart P;
    chemical, physical, and  biological treatment  units in Subpart Q; or  underground
    injection control (UIC) wells in  Subpart R. As a consequence, facilities operating in
    interim status pursuant to these subparts could never receive final  permits.  In
    addition, new thermal, chemical, physical, and biological treatment facilities could
    not be constructed, since new hazardous waste facilities need a permit before
    construction  commences.

    The promulgation of Part 264, Subpart X, miscellaneous unit regulations bridged the
    gap between Part 265 and Part 264. Subpart X allows for the construction and
    permitting of units that  do not meet the Part 264, Subparts I through W and DD, and
    Part 266, Subpart H, unit descriptions.  It "also allows interim status  facilities with
    units which are not specified in these subparts to become fully permitted, to
    construct new units, or to expand existing units.

                       2.   REGULATORY SUMMARY


The RCRA regulations governing the management of hazardous waste at treatment,
storage, and disposal facilities (TSDFs) are divided into general standards that apply
to all facilities and unit- or process-specific standards. All thermal treatment units;
chemical, physical, and biological treatment units; underground injection control
(UIC) wells; and miscellaneous units are subject to the general facility standards in
Parts 264/265, Subparts A through H (with the partial exception of UIC wells).
Accordingly, an owner/operator must comply with personnel training; general waste
analysis; preparedness and prevention procedures; contingency plans; special
requirements for the handling of ignitable, reactive, or incompatible wastes;
corrective action; closure; and any other applicable requirements.

In addition, each type of unit or process must-comply with the relevant unit/
treatment process-specific subpart in Part 264/265. This module outlines the unit/
treatment process-specific design and operating requirements for the following types
of hazardous waste management units:

      • • Part 265, Subpart P - Thermal Treatment

      •  Part 265, Subpart Q - Chemical, Physical, and Biological Treatment

      •  Part 265, Subpart R - Underground Injection

      •  Part 264, Subpart X - Miscellaneous Units.


2.1   THERMAL TREATMENT UNITS (SUBPART P)

Since incineration was the most prevalent method used to thermally treat hazardous
waste in 1980, EPA established a subpart devoted specifically to this thermal waste
management technique (Subpart O).  The Agency realized, however, that hazardous
waste may be thermally treated in units other than incinerators.  So as  not to
discourage the development and use of alternative thermal treatment processes, EPA
also promulgated interim status regulations for thermal treatment units that do not
meet the definition of an incinerator, boiler, or industrial furnace.  Thermal
treatment is defined as the treatment of hazardous waste in a device that uses
elevated temperatures as the primary means to change the chemical, physical, or
biological character or composition of the hazardous waste (§260.10). Thermal
treatment units include carbon regeneration units and devices employing processes
such as molten-salt pyrolysis, calcination, wet-air oxidation, and microwave
destruction. Since incinerators are a subset of thermal treatment units, many of the
Part 265, Subpart P, requirements are similar to the Part 265, Subpart O, standards.

4 - Miscellaneous and Other Units
OPERATING REQUIREMENTS

Before adding hazardous waste to a thermal treatment unit, the unit must be
operating under steady-state (normal) conditions of operation (§265.373).
Owners/operators may use auxiliary fuel or other means to bring the unit to
operational readiness before burning hazardous waste. The owner/operator must
also perform waste analysis to determine the heating value of the waste, the halogen
and sulfur content of the waste, and the concentrations of lead and mercury in the
waste (§265.375).  In addition, owners/opera tors are required to conduct monitoring
and inspections of the temperature and emission control instruments, the stack
plume, and all process and ancillary equipment (§265.377).  At closure, all hazardous
waste and hazardous waste residues must be removed from the thermal treatment
unit.  Finally, unless the thermal treatment unit receives  a special certification, the
unit may not treat dioxin-bearing hazardous wastes (F020, F021,  F022, F023, F026, or
F027) (§265.383).

OPEN BURNING AND OPEN DETONATION

Open burning and open detonation (OB/OD) of hazardous waste is prohibited in
interim status thermal treatment units, except for OB/OD waste explosives. Waste
explosives include waste that  has the potential to detonate and bulk military
propellants that cannot safely be disposed of through other modes of treatment.
OB/OD must be performed in a manner that does not threaten human health or the
environment, such as following minimum distance requirements for treatment
near adfacent properties (§265.382).
2.2   CHEMICAL, PHYSICAL, AND BIOLOGICAL TREATMENT UNITS
      (SUBPART Q)

Facilities may conduct chemical, physical, and biological treatment of hazardous
waste in units other than those specifically addressed in Part 265, Subparts I through
O, W and DD. Examples of treatment processes that are often not performed in
RCRA-defined units include distillation, centrifugation, reverse osmosis, ion
exchange, and filtration. To accommodate these unique units, the Agency
promulgated interim status regulations for units that treat waste by chemical,
physical, and biological treatment technologies in Part 265, Subpart Q.  The Agency's
primary concern was the safe containment of hazardous waste, hazardous waste
constituents, and treatment by-products.  As a result, Subpart Q  standards resemble
the container and tank standards in Part 265, Subparts I and J, respectively.

OPERATING REQUIREMENTS

The operating requirements for Subpart Q units specify that waste may not be placed
in the equipment if it could cause the process or equipment to rupture, leak, corrode,

                 but is an introduction to the topic used'for Hotline training purposes.

         or otherwise fail. In addition, where wastes are continuously fed into a process, the
         units must be equipped with a feed cut-off system (§265.401).

         Subpart Q units must also comply with special requirements for ignitable or reactive
         wastes in addition to the general requirements for these wastes that apply to all
         RCRA facilities (§265.405). These standards require the owner/operator to remove
         the hazardous waste characteristic immediately before or after placement in the
         treatment process .or equipment.  Likewise, Subpart Q units must comply with
         special requirements for waste analysis in addition to the general waste analysis
         requirements (§265.402). Whenever a waste is to be treated by a  process that is
         substantially different from  any previous processes, the owner/operator must
         conduct waste analyses and trial treatment tests or obtain written documentation
         showing that  the treatment  will meet the applicable requirements.

         Facilities must also inspect discharge control, safety equipment, and data gathered
         from monitoring equipment at least once each operating day. In addition, facilities
         are required to inspect the construction materials of the treatment process and
         confinement structures at least weekly for corrosion, erosion, or leakage (§265.403).
         At closure, all hazardous waste and hazardous waste residues must be removed from
         treatment processes or equipment, discharge control equipment, and discharge
         confinement structures  (§265.404).
        2.3   UNDERGROUND INJECTION (SUBPART R)

        EPA originally intended to regulate underground injection control (UIC) wells
        disposing of hazardous waste primarily under the Safe Drinking Water Act (SDWA).
        At the inception of the RCRA program, however, many states did not yet have a
        SDWA-approved UIC program.  EPA promulgated the interim status regulations for
        existing UIC wells to address this period when UIC wells were being used to dispose
        of hazardous waste but were not yet subject to the SDWA.   EPA never intended to
        promulgate Part 264 final permit standards for UIC wells, since §270.60(b) allows a
        UIC permit to function as a RCRA permit-by-rule once corrective action has been
        performed for all solid waste management units (SWMUs)  at the facility.

        Class I and Class V wells injecting hazardous waste must have authorization under
        both SDWA and RCRA.  A well has SDWA authorization  once it obtains a permit
        issued under 40 CFR Part 144 or 145. A well is considered  to have RCRA
        authorization when it meets one of the following conditions: qualifies for and
        maintains RCRA interim status; obtains a UIC permit and meets the requirements
        for  a RCRA permit-by-rule; or obtains a RCRA Part B permit for  all units, including
        the operating well.

        The first option would allow the well to obtain RCRA interim status.  The RCRA
J/-      interim status regulations"Tspecify that UIC wells injecting hazardous waste are
-a  -    subject to all the ;ParT'265'genferal-faci;liry;standards, except closure (Subpart G) and
                                                      representation of EPA's regulations or policies,
                       -tri'but is^n' introduction to the topic used for Hotline training purposes.

6 -.Miscellaneous and Other Units
financial assurance (Subpart H).  The second option allows a well to qualify for a
RCRA permit-by-rule.  To obtain a RCRA permit-by-rule, the well must obtain a
SDWA underground injection permit pursuant to Parts 144 and 145 and comply
with §144.14 for wells managing hazardous waste (§270.60(b)). Finally, the UIC well
may obtain  a final RCRA permit. UIC wells may receive RCRA permits as
miscellaneous units.                                               .

Because all Class I and Class V wells injecting hazardous waste require permits or
permits-by-raJe under RCRA Subtitle C, certain RCRA standards apply to these wells
even if they have a permit-by-rule.  Most significantly, they must comply with
corrective action requirements.  Likewise, any associated hazardous waste storage
units at the UIC well facility must be permitted and would also be subject to
corrective action.
2.4   MISCELLANEOUS UNITS (SUBPART X)

On December 10, 1987, EPA promulgated standards regulating miscellaneous units in
Part 264, Subpart X (52 FR 46946). The promulgation of Subpart X extended RCRA
permit eligibility to interim status units performing thermal, chemical, biological, or
physical treatment under Part 265, Subparts P, Q, and R.  Additionally, new and
innovative technologies managing hazardous waste in units not previously
regulated under RCRA became eligible for RCRA permits as miscellaneous units.

In developing the Subpart X regulations, the Agency wanted to promulgate a new set
of general standards that would cover the diverse technologies and units not yet
covered in Part 264.  To accomplish this goal, the Subpart X  regulations are general,
not technology-specific. In sum, miscellaneous units are  required to be located,
designed, constructed, operated, maintained, and closed  in a manner that will
prevent any unsafe releases into the groundwater, subsurface environment, surface
water, Wetlands, soil surface, or air. This media-based or  pathway-based approach
ensures that any potential problems arising from units are addressed.

The Agency regards the Subpart X regulations as environmentally more protective
than the corresponding interim status regulations found  in Part 265, Subparts P, Q,
and R. Since the site-specific Part 264 permit provisions are tailored to specific
facilities, these standards provide better environmental protection.  Subpart X is also
more flexible, as it allows new and innovative technologies to receive RCRA
permits.  In addition, these regulations give the implementing agency the flexibility
to develop permit standards on a  case-by-case basis when considering the technology-
specific data required to be submitted by the applicant.

The following portion of the module describes and presents an overview of the types
of units regulated by Part 264,  Subpart X, and outlines the types of performance
standards specified in the regulations.  In addition,jthe section summarizes the

                                                        Miscellaneous and Other Units - 7
monitoring, analysis, inspection, response, reporting, corrective action, and closure
requirements  for miscellaneous units.

TYPES OF UNITS COVERED BY SUBPART X

Miscellaneous units are defined as hazardous waste management units where
hazardous waste is managed in a unit other than a container, tank, surface
impoundment, pile, land treatment  unit, landfill, incinerator, boiler, industrial
furnace, underground injection well, containment building, or  unit eligible for a
research, development, and demonstration (RD&D) permit (§260.10).  Since Subpart
X is intended to serve as a "catch all" category,'the Agency did not develop an all-
inclusive list of units designated as miscellaneous units.  The Agency, however, felt
it would be  helpful to identify  several types of units that may receive permits under
Subpart X. The types of units subject to Subpart X include, but are not limited to:

     •   Placement of hazardous  waste in geologic repositories other than injection
         wells                                       .

     •   Placement of hazardous  waste in deactivated missile  silos other than
         injection wells or  tanks                    ,

     •   Thermal treatment units other than incinerators, boilers, or industrial
         furnaces

     •   OB/OD of waste explosives

     •   Chemical, physical, biological treatment units.                   .

The Subpart X regulations do not regulate:

     •   Units regulated  under other portions of Parts 264 or 266

     •   Units excluded from permitting under Parts 264 and 270

     •   Underground injection wells (Part 146)

     •   RD&D units covered  under Part 270.

PERFORMANCE OBJECTIVES

The Agency concluded that it would be  impossible to set technology-based design and
operating standards for the  enormous diversity of technologies eligible for a permit
as a miscellaneous unit. Instead, EPA provided a set of objectives designed to protect
groundwater, surface water (including wetlands), air, and soil from the migration of
hazardous constituents.  The performance objectives require permit applicants  to
evaluate the potential  environmental impacts of the unit or facility and to

-------
8 - Miscellaneous and Other Units
demonstrate that the unit will not adversely affect human health and the
environment (§264.601),

This performance-based regulatory approach offers several advantages.  First, it
allows the Agency the flexibility to address a full range of environmental issues
raised by any waste management situation without the need to develop specific
design and operation conditions.  Second, for those Subpart X units resembling
conventional units, the permit may incorporate appropriate requirements from
Subparts I through O, W and DD, and Part 266, Subpart H.  For example, a
miscellaneous unit that is similar to a surface impoundment may be required to
have liners and a leachate collection system. Third, this approach allows.the
implementing Agency the flexibility to  tailor each permit to meet the particular
issues and circumstances based on the technology used, the types of waste, the site.
location, and the  regional meteorological, climatic, and hydrogeologic characteristics.

PERMIT REQUIREMENTS

All owners/operators of miscellaneous units must obtain a permit to treat, store,
and/or dispose of hazardous waste. The Subpart X permitting standards require
permit applicants to describe the unit and evaluate the potential environmental
impacts of the unit or facility (§270.23).

The permit application must include information that clarifies and defines the type
of unit for which the owner/operator is seeking a permit.  The applicant must
describe the unit, its physical characteristics, construction materials,  and dimensions.
The bulk of the application is expected  to contain detailed plans and engineering
reports describing the unit location, design, construction, operation, maintenance,
monitoring, inspection,  and closure.

In addition, each of the  environmental  performance standards must  be assessed.
The permit application must contain information on  the potential pathways of
human or environmental exposure to hazardous waste or hazardous constituents.
Where this assessment indicates  that releases to air, surface water, or groundwater
are possible, the applicant is expected to provide details on the potential magnitude
and nature of such exposures, as well as detailed hydrologic,-geologic, and
meteorologic assessments and maps for the region surrounding the site (§270.23).

MONITORING, ANALYSIS, INSPECTION, RESPONSE, REPORTING, AND
CORRECTIVE ACTION

Each miscellaneous unit must have monitoring, testing, analytical data, inspections,
response, and reporting procedures.  These procedures ensure that a unit is  in
compliance with  the general performance standards.  The required activities are
included in the unit's permit.  At a minimum, the monitoring program should  be
capable of determining the unit's impact on groundwater, air quality, surface and
subsurface contaminant migration; although in many cases, monitoring of a specific

medium will not be necessary.  It should also ensure compliance with the general
inspection requirements, testing and maintenance of equipment schedules,
reporting requirements, and corrective action (§264.602).

CLOSURE

Units that cannot clean-close require post-closure care.   The unit must meet all of the
environmental performance standards, as well as the appropriate post-closure
standards of Part 264, Subpart G, during the post-closure care period (§264.603).

On November 8, 1995, EPA issued a proposed rule clarifying when military
munitions (including chemical munitions) become hazardous wastes (60 FR 56468).
The rule addresses when unused munitions become a solid waste, RCRA's
applicability to fired or used munitions, the regulations applicable to hazardous
waste munitions, and the protocols for emergency situations.  It also proposes an
amendment to the definition of on-site.  EPA expects to finalize this proposal in
December 1996.

                            4.  SPECIAL ISSUES

Keep in mind the following points about how miscellaneous units relate to other
RCRA issues.
4.1   MOBILE HAZARDOUS WASTE TREATMENT UNITS

Mobile treatment units (MTUs) are designed to move from facility to facility treating
waste on-site.  These units must comply with the applicable interim status or
permitted unit standards. If the MTU does not meet the description of any of the
units regulated under Subparts I through O, W and DD of Part 264 or Subpart H of
Part 266, then permitting under Part 264, Subpart X, is required. Current regulations
require MTUs  to undergo RCRA permit procedures at each site of operation.  See the
module entitled  Permits and Interim Status for more information on permitting
MTUs.
4.2   LAND DISPOSAL RESTRICTIONS (LDR)

Many units permitted under Subpart X also meet the definition of a land disposal
unit under RCRA (i.e., underground mines or caves).  Therefore, any hazardous
waste prohibited from land  disposal must be treated to meet applicable Part 268
treatment standards prior to placement in the unit.

The Part 268 land disposal restrictions'  applicability to open burning and OB/OD
units requires further clarification.  When waste explosives are detonated in RCRA
OB/OD units, wastes are typically managed on the  ground.  The Agency has
concluded that.OB/OD of waste explosives does not constitute land disposal because
it is treatment rather than disposal. This may not be true, however, in cases where
the residues from the OB/OD operation remain a hazardous waste. In these cases,
the practice of allowing the  remaining  wastes to remain on the ground or to seep
into the ground may be considered land disposal.
4.3   AIR EMISSIONS

When appropriate, a miscellaneous unit's permit must include the air emission
control requirements of Subparts AA, BB, and CC. Subpart X miscellaneous units
are permitted on a case-by-case basis with terms and provisions as needed to protect
human health and the environment.  Appropriate portions of the existing technical
standards for other waste management units, such as the air emission standards, will
be incorporated into a permit as necessary.
   The information in this document is not by any means a complete representation of EPA s regulations or policies,
                 but is an introduction to the topic used for Hotline training purposes.
