Summary:

     Applicants for permits for mobile treatment units should use the model
application and permit developed at the first permitted mobile treatment unit
site to expedite permit processing at subsequent sites.

     Under RCRA, a mobile treatment unit must obtain a permit for each site where
it intends to operate.  To reduce the burden on such units, RCRA regulations
allow the permittee to submit results of a validly conducted trial burn in lieu
of a trial burn plan at subsequent sites.

     The EPA promulgated final regulations on January 14,  1985, listing several
dioxln waste streams as acutely hazardous wastes.  The regulations which go
into effect July 15, 1985, require interim status as well  as permitted inciner-
ators to demonstrate that they have a "99.9999% ORE for each principal organic
hazardous constituent (POHC) designated ....  This performance must be
demonstrated on POHCs that are more difficult to incinerate than tetra-, penta-,
and hexachlorodibenzo-p-dioxins and dibenzofurans."  A RCRA permit cannot be
issued for dioxin wastes until July 15, 1985.  If a RCRA permit is issued before
that date, and the applicant wants to add any of the new listed wastes to their
permit, it would require a major modification of the permit.

     Mobile incinerators must be treated as new facilities when operated in
areas that differ from the area specified In the original  operating permit
and therefore satisfy additional regulatory requirements.  Substantive
procedural requirements for permitting include establishment of a statement of
basis and an administrative record supporting each operating condition in the
permit, and public participation in the decision making process.

Tot       Joe Galbraith
          Permit Writer, Region 7TI


     I have completed my review of ORD'a application to operate
the Mobil* Incinerator at the Denney Para site in Missouri.  I have
several general comments that I will discuss in this memo and
specific comments that are set forth in the attached PAT document.

     My first concern is that there are several major deficiencies
in this application.  These deficiencies are of such a nature that
this application* in its current font, will not support the issuance
of a RCRA permit for incineration.  These deficiencies could have
been avoided by complying with the attached po'licy from the Assistant
Administrator on permitting mobile treatment units.

     The objective of the mobile treatment unit policy is to
facilitate the issuance of peraits to such units by developing a
model application, and. permit at the first site where the unit is
permitted.  The applicant could than use this model application and
permit to expedite permit processing at subsequent sites.  The model
application and permit for this facility were developed in Region
II.  ORO should have used those models to prepare its subraittal to
Region VII.  ORD, however, submitted an entirely new application.
This aew application fails to address several major issues which
were resolved in the original application and perait.

     In the inerest of time, I urge you to encourage ORO to submit
the model Region II Kin-Buc application to Region VII along with a
letter incorporating all relevant portions of the Region II appli-
cation by reference.  In the meantime, you should encourage ORE to
implement the mobile treatment unit policy by revising the site-
specific portions of the model application so that document can
stand on its own as the basis for permitting this incinerator.

     My second concern is that ORO appears to believe they can get
a national RCRA permit by satisfying the trial burn requirements in
Region VII.  RCRA makes it clear that a mobile treatment unit must
get a permit for each site where it intends to operate.  While this

-------
imposes a burden on mo5He  treatment units, both the  regulations
and the taobile treatment unit policy provide some relief.   First,
the regulations allow ORD to su'Mait the results of. a  validly eon-
ducted trial burn in lieu of a trial burn plan at subsequent sites,
thereby saving the coat and effort of conducting an additional
trial burn.  Second, the Mobile treatment unit policy reduces the
amount of time necessary to prepare and review the new application
becauaa significant portions should have already been reviewed.  In
no case, however, do the regulations or the mobile treatment unit
policy allow for a nationwide RCRA perait.

     My third concern is the reoeated references to a RCRA  permit
to incinerate TCDD.  TCDO is not now a RCRA hazardous waste.  The
Agency has proposed regulations listing TCDD as a hazardous waste
but these regulations have  not been pronulgated.  Until  the final
rule is published in the Federal Register, the Arjency cannot assume
in advance what technical standards will be required  to  treat, store
or dispose of TCDO and cannot issue a perait for the  treatment,
storage or disposal of TCDD.  He can conduct a trial  burn using
TCDD as a POHC because it is listed in Appendix VIII.  ORO  is free
to conduct such tests with  the goal of demonstrating  99.9999% DR£
but mist keep in aind that  there is no assurance this will  be the
standard once the dioxin rule becomes final.  Finally, if ORD
receives a RCRA pemit and  the dioxin rule is promulgated and
beeones effective before ORD has completed its activities,  a major
modification to the perait  may b*j..necessary.

     All parties must recognize that the Mobile Incinerator oust be
treated as a new facility at the Denney Para site.  The  Mobile
Incinerator does not have interim status in Missouri  and its perait
is for operations at Kin—Buc in Region II.  Since the unit  aust be
treated as a new incinerator, several additional regulatory require-
ments- nust be satisfied.  ORD has not addressed these requirements
in the submission to Region VII (see specific comments), although
these were addressed in the model application.

     Finally, many people in the Region and Headquarters are familiar
with this unit, its details of operation, and its capabilities.  1C
the only substantive procedural requirement was to satisfy  the
pemit writer that the incinerator could an

The applicant also needs to provide

the trial burn but before final permit
sodification.  This information could be
supported by the original application and

these docunents by reference.  The regula-

                          The applicant fails, however/ to prop so an
                          acceptable aritifical feed.  The applicant
                          proposes to use PC3s and CC14 absorbed on
                          Imbiber beads and mixed with sand as a
                          surrogate for contaminated soil.  labiber
                          beads provide aa organic and, therefore,
                          aoobustible ma,trix for containment of
                          the POHCa.  The actual POKCs, however,
                          will be absorbed on contaminated soil, a
                          relatively inorganic and, therefore,
                          incombustible matrix,  while it is irrele-

                          relevant to a determination as to whether

                          The applicant's statements as to tne
