Summary:
#9525.01(82)

1-29-82
     Mobile treatment units alone cannot receive permits, but must be permitted
for use at a particular location because RCRA permits are site specific.

     An approach is set forth enabling mobile treatment units to operate within
the scope of the RCRA permit program for the following situations:

     1.  Non-emergency situations at sites with interim status;

     2.  Non-emergency situations at sites with RCRA permits;

     3.  Non-emergency situations at sites which do not have interim
         status or RCRA permits; and

     4.  Emergency situations.

     For a more complete discussion of these situations, please refer to the
original memorandum.

     Thia is in response to your meirorandum  of  September 25,  1921,
request1' na concurrence with your proposed  mechanism to handle
mobile treatment facilities.

     We agree with Eeoion I V s  interpretation of  the regulations,
that interim status and PCPA permits  are site specific and there-
fore, mobile treatment units alone  cannot  receive permits (or
interim status) but must be permitted (or  receive interim status)
for use at a particular location.   We have  written at least  one
letter to that effect.  (See letter from John STcinner to Timothy
Vanderver of Chemfir Technologies,  Inc. dated June 2,  1?P1,  gent
to the Regions on that date).

     The following aporoaoh, which  is scnewh at  similar to tjie cr»
suggested In your memorandum, will  enable  mobile  trrat? within, the seep* of  the  PCPA nrrcrfiw.   TV-»S approach
has b«»cn developed a^ter meeting wi^h SOVJM-S* mobile troatment
companies.  V-> he^>*» r'iv'ded the i»»»rroach  into the following four
           '!) Wen-erne rg«ncy  situations  at  a site which has
              interim status-

           (2) Non-emergency  situations  at  ? site which has
              a PCPA permit  (e.g.,  periodic use  of mobile
              treatment  units  during  the operating li Ft* of
              the  facility,  use  ft  closure)

-------
           (3) Non-emergency  situations  at  a site  which  does
              -not have interim  status or '-a  RCFA permit  (e.g. ,
              remedial actions  at  inactive  sites);

           (4) Emergency situations  (e.g., spills, emergency
              response).

 (I)  Non-emergency situations at a  site which has interim  status

     This  approach would enable a mobile treatment  unit to operate
 during interim status under  one 6f  three alternatives.  (Alternative
 (c) will be proposed soon  as an amendment to 40 C.P.R.  §122.23,
 Changes during interim status).

     (a) An interim status facility which intended  to use  mobile
 treatment  equipment, but did not include it in the  original Part A
 permit application, may amend its Part A application to include the
 mobile treatment process.  The Agency would treat these facilities
 as it would any facility which  submitted an incomplete  Part A permit
 application.  The only requirement  is that the equipment must have
 been in existence on or before November 19, 1980,1  and  the facility
 must have  qualified for interim status.

     (b) Mobile treatment nay be added to a facility as a  new process
 or an increase in the design capacity of an existing process under
 the allowable changes during interim status, 40 C.F.R.  5122.23(c)(2)
 or (c)(3).  Under these sections, a mobile treatment unit  may be
 added to a facility if it  is necessary either to prevent a threat to
human health and the environment because of an emergency situation;
 to comply  with Federal regulations or state and local laws? or because
 of a lack  of available treatment, storage,  or disposal  capacity at
 other facilities.  It should be noted, however  that these sections
will change with the amendment to $122.23.

     (c) The proposed amendments to 122.23(c) will  include a section
which will allow interim status facilities to add tanks and containers
 used for the treatment or  storage of hazardous waste.   Such tanks and
 containers may- be added for.  any reason,  whether or  not  the facility
!/ Because mobile treatment units  are unique in that they are used
Intermittently at different sites, they will be considered in exist-
ence if they were operating at any site on or about November 19,  1980.
Normally, a unit would have tp be operating on or about November  19,
1980, at a site which qualified for interim status to be considered
in existence.
                             ^" f* *"*

previously had tanks or containers, or  a.ny  treatment  or storage
process.  The facility must have quail fi;ed  for  interim  status, how-
ever.  This amendment, if promulgated as  proposed,  will enable most
interim status facilities to  add mobile treatment done  in tanks or
containers to their facilities.

(2) Non-emergency situations  at a site which has a  PCPA permit

     A mobile treatment unit  may be added to a  permitted facility
under §122.15 as a permit modification.  Section 122.15(a)(l)
allows a permit to be modified, or revoked  end  reissued when  sub-
stantial alterations or additions to the permitted  facility or
activity occur

     We will be proposing amendments to §122.17 which,  in some
limited circumstances, may allow the addition of mobile treatment
units to be consider*** minor  modifications  to a facility.

(3) ETon-Rmergency situations  at a site which does not have
    interim status or * PCPA  permit

     Our approach is to require a permit before a mobile treatment
operator may begin operation  at a non-emergency site which does not
have interim status or a PCPA permit.  In most  situations where the
mobile treatment company is handling t* ccn-
sider^d both c-wner (o^ th*» equiprr^nt:) end curator, and imi«t  roply
for a permit.   If there is another owner involve as well, e.a.,
owner of the land, that owner may also havo to  sign the permit
app]ication.

(4)  Emergency Situations

     There are two emergency  mechanisms already in  place in the PCRA
regulations.  First,  storage  or treatment done  in immediate response
to a spr11 of hazardous waste may cccnr without first obtaining a RCPA
permit". (S^e 40 CFT *264.1 (g) (8), 45 PP 76630,  November 19, 1990).

     Secorr?, there is a provision *or an emergency  permit in  40 CFP
§122.27.   This is* a temporary permit to be used in  the  event  that
treatment, storage, or^ disposal of hazardous waste  must take  place
due to an emergency situation.

     Your concept of a generic permit would allow the mobile
treatment operation itself to obtain a permit,  and  then  require
public nctic«» before the mobile treatment operation is  used at
each individual site.   The concept is obviously a departure from
the present RCPA scheme of aite specific permits.   We will lock
into this suggestion ^urther.  In the meantime,  the approach
described in this met^orandum  must be used.
