SUBJECT:  Closure Requirements

FROM:     Marcia E. Williams
          Director
          Office of Solid Wa

           Director
           Waste Management Division
           EPA, Region VII
      This memorandum is in response to your memorandum of
 December 17, 1987, which posed a number of questions  related to
 implementation of the closure regulations.  As  you  know,  we
 have discussed the issues over the phone with you several times
 since receiving your memo, both in the context  of general
 policy, and also in the context of applying these policies to
 .specific situations.  We have responded to each point in  turn.

 Response to point 1:

      Your question concerns the consistency between the new
 tank system regulations (51 FR 25422, July 14,  1986), which
 include post-closure care, and the closure requirements for
 container storage units.  Since we have now revised the tank
 system standards as of July 14, 1986, we recognize  that there
 are inconsistencies with the present container  standards.   We
 agree that the container storage requirements in Subpart  I of
 40 CFR Part 264 and 265 should be revised so that the Agency
 will have: a consistent overall policy for closure of  storage
 and treatment units.
          •ts -
          viT~ — -•
 Response to point 2:

      You requested guidance on whether the clean closure  policy
 for surface impoundments contained in the March 19, 1987
 Federal Register notice, can be applied to all  hazardous  waste
 management units in Iowa (which does not have final RCRA

-------
                                       OSWER DIRECTIVE # 9476.00-12
                               -2-

authorization).   The clean closure policy that was contained in
the March 19, 1987 Federal Register should be applied to
closures by removal of wastes from any RCRA regulated unit.
Regulated units include landfills, surface impoundments, waste
piles, and land treatment units.  The regulatory language
governing the level of cleanup described in each of the
following sections, 264.197, 264.228(a), 264.258(a), 265.197,
265.228(a), and 265.258(a), is identical.  Since the
consequences of achieving clean closure are the same,
regardless of type of unit, the general policy contained in the
March 19, 1987 FR notice, and the specific details regarding
the setting of cleanup levels in each medium that are contained
in the upcoming "Surface Impoundment Clean Closure Guidance
Manual", should be applied consistently to all units that close
by removal of wastes.  Another guidance document, "Clean
Closure of Hazardous Waste Tank Systems and Container Units",
is currently being developed.  It is consistent with the manual
for clean closure of surface impoundments; differing only where
necessary because of the unique nature of tank systems and
containers.

     As stated in the March 19, 1987 preamble, clean closure
cleanup levels are to be based on Agency-approved health based
limits, rather than background, except where no such
Agency-approved limit exists, and then background may be used
as the basis for setting cleanup levels.

Response to point 3:

     As currently envisioned, the proposed changes to the
closure regulations would allow a landfill to defer closure to
manage non-hazardous wastes only if certain demonstrations are
made.  Key among these is that managing non-hazardous wastes
will not be incompatible with prior management practices.  The
preamble will include a discussion of potential incompatible or
detrimental effects which are to be considered in evaluating a
request to defer closure.  For landfills these concerns
include: subsidence, increased leachate formation, cap
settlement and gas production.  These potential detrimental
effects could support a finding of incompatibility, which would
be grounds for disapproving a deferred closure request.

     This rule change will not affect enforcement actions.  The
opportunity to defer closure will be afforded to both permitted
and interim status units.  Facilities with units which have
lost interim status can receive an operating permit which
includes the LOIS unit.  Waste receipt would not be allowed in
the LOIS unit prior to permit approval.

                               -3-

Response to point 4

     You have requested guidance on the issue of whether
changes may be made at facilities operating without a permit or
interim status and LOIS (loss of interim status) facilities
under Section 270.72 when necessary to comply with corrective
action and closure plans.   This issue was raised in the context
of the rule, proposed on August 14, 1987, 40 CFR Parts 265, 270
and 271 entitled "Changes to Interim Status and Permitted
Facilities for Hazardous Waste Management; Procedures for
Post-Closure Permitting; Proposed Rule".  We are currently
considering this issue and will address it in the final rule
scheduled for Summer 1988.

Response to point 5

     Your first question,  in 5a and b, concerns your
interpretation of 40 CFR Part 261 and the March 19, 1987
Federal Register notice, as they apply to wastes resulting from
closure. Your interpretation is correct.  As you stated, a
characteristic waste must be managed under Subtitle C unless
the material no longer exhibits any of the four characteristics
specified in Part 261, Subpart C.  It would not be sufficient
to merely demonstrate that the materials no longer exhibit the
one or more characteristics that had originally brought the
waste under Subtitle C regulatory control.  A waste that is
listed as hazardous under Part 261, Subpart D, and any waste
residues or contaminated soil or debris that are removed from a
unit during closure operations, are considered to be hazardous,
unless the waste materials have been delisted, in accordance
with Section 261.3.

     Your first bullet point within point 5 referred to how
DOD/DLA (Department of Defense/Defense Logistic Agency)
recommends, in their "Conforming Storage. Model RCRA Permit
Application" (which accompanies their model permit), to
determine whether or not decontamination washwater at a site is
hazardous.  As mentioned above, the determination should be
based on whether or not the waste exhibits any of the four
characteristics specified in Section 261.20.  TOC and TOX are
indicator parameters only.  Therefore the DOD/DLA Model Permit
Attachment for Closure is incorrect when it implies that the
concentrations of TOC and TOX define whether or not washwater
is hazardous.

     EPA has commented on this closure plan application
extensively. DOD, however, has not responded to all of our
comments on the model permit.  Therefore, as we said in the
August 8, 1987 cover memo to the model permit, EPA may request
different or additional information if a permitting authority

-------
                                       OSWER DIRECTIVE # 9476.00-12
                               -4-

finds part or all of the model permit application to be
inappropriate.  Copies of both the cover memo and EPA's
comments on DLA's conforming model permit application are
attached for your reference.  Please note EPA comments
regarding waste analysis and the closure plan.  We recommend
that you use the recent draft report, "Clean Closure of
Hazardous Waste Tank Systems and Container Units" instead as a
guide to closure.

     Your second bullet point within point 5 asked why, in
certain situations, non-hazardous material must be removed from
a landfill for clean closure, but then could conceivably be
re-deposited legally in a sanitary landfill.  We share your
concern that this could be viewed as an inconsistency within
our regulatory program.  Two regulatory efforts, however, are
currently underway which should address this potential
problem.  You alluded to the first effort, redefining hazardous
waste, in your memo.

     As we move more towards concentration-based listings,
inconsistencies may occur less often.  You should note,
however, that the basic reason why action levels in the clean
closure situation are not consistent with hazardous waste
identification levels is that action levels in the clean
closure situation are based on the more protective of two
possible scenarios: the direct ingestion of soil and ingestion
of contaminated ground water, assuming no attenuation in the
unsaturated zone or dilution in the ground water.  The
delisting levels, on the other hand, are based strictly on
ground water ingestion, and are derived from a generic model
that accounts for vertical and horizontal spreading of
contaminants over a 500 foot distance in the aquifer.  This
difference may well remain even if changes are made in how
hazardous wastes are listed.  The answer to the problem is to
complete the Subtitle D regulations for municipal landfills and
surface impoundments.  The result of these more stringent
regulations should be that if waste is removed from a landfill
for clean closure and re-deposited in a sanitary landfill, that
the new landfill will be more protective of the environment
than the original one.

     We hope you will find this memo to be useful to you in
interpreting these issues related to the implementation of
regulations regarding closure.  Please contact Hope Pillsbury
of my staff at FTS 475-6725 if you have any questions regarding
this memo.

SUBJECT:  DOD/DLA Conforming Storage Model  RCRA Permit
          and Model Permit Application

FROM:     Marcia Williams, Director M ^JCM^ i^^^
          Office of Solid Waste  "   (

TO:       Hazardous Waste Division Directors,  Regions  I-X

     The Office of Solid Waste has'been  working with the  Defense
Logistics Agency (DLA) to develop a model permit application  and
a model RCRA permit for DLA's Defense Reutilization  and Marketing
Service  (DRMS) storage facilities.  This memorandum  transmits
the final documents for your use.

     A copy of the model application for the DLA conforming storage
facility is being sent to you as  a reference guide to  the model
RCRA permit.  The model application is based on actual submittals
by DRMS to many of the Regions and States.   The model  application
has been reviewed by the Headquarters Incineration and Storage
Permit Assistance Team (PAT) and  a Regional  and State  Workgroup.
However, this review must be supplemented by a  detailed review
at the time the site-specific application is received.  Many  of
the sections of the application will change  when DLA includes
site-specific information (e.g.,  the facility's contingency plan
or a list of waste to be handled).  Also, different  or additional
information maybe requested if a permitting authority finds
part, or all, of the model permit to be  inappropriate.

     The model permit is to be utilized  in  conjunction with the
model permit application.  Spaces are provided  for inserting
information and brackets [ ] are  placed  to  designate optional
sections or phrases, as well as notes to the permit  writer.   All
brackets, inappropriate phrases,  and notes  should be deleted
by the permit writer.

     Although DRMS might not be the owner or operator  of  solid
waste management units (SWMUs) at each base,  their permits must
address corrective action for these SWMUs.   To  provide an example
of specific conditions relating to corrective action,  excerpts
are included in the model permit  from a  permit  prepared by EPA
Region III for the Defense General Supply Center.

                              - 2 -
     I hope the attached model application and the model RCRA
permit aid you in drafting permits for the DLA conforming storage
facilities.  If you have any questions regarding the DLA storage
facilities and the use of these guidances, please contact
Chet Oszman at FTS 382-4499.  Also, I want to thank those
Regions and States who participated in the review of the model
application.

     The Regional and State workgroup  has completed its review
of the Defense Logistics Agency  (DLA)  conforming storage facility
model permit application.  A summary of their  comments is attached

     You will note that the bulk of the Workgroup's comments are
on the waste analysis and process  information  sections of the
model application.  To improve the quality.of  the model applica-
tion, you should amend it, responding  to all of  the Workgroup's
concerns.

     A.T. Kearney (our contractor) has  been instructed to begin
development of the model permit.  However,  completion of the
model permit relies on your response to the attached comments..-.
Therefore,  we will need to meet  with you at your earliest con-
venience .

     If you have any questions or would like to  discuss the
comments, we can plan a conference call with the participating
workgroup members.  In the meantime, please continue to work
directly with Chet Oszman.

                      DLA CONFORMING STORAGE
              REGIONAL and STATE WORKGROUP COMMENTS


IN GENERAL

1.  Generally, the model is a significant  improvement  over past
DOD efforts in this area.  The main area needing  additional  work
is the waste  analysis plan.

INTRODUCTION

1.  (page 5)  Regarding the first sentence of  section  (a)(l),  the;.
permitting authority would need to make a determination during
the review of the site specific information,  that  there is suf-
ficient evidence that noncompatible hazardous materials/hazardous
waste will be fully isolated from each other.

2.  (page 7)  Regarding section (d)(l), the design  of  each storage
room or compartment must be verified during the review of site
specific information.  Stating that it is your intent  to meet
the regulatory provision is not sufficient to demonstrate "how"
you will meet that provision.

3.  (page 10) Regarding section (e), the first two bullets,  the
terms "sealed" needs to be described.  How are they sealed?    •:«'-

SECTION A

1.  The actual wastes to be stored must be indicated  in the  permit
application,  along with the precise storage area  in which this
waste will be stored.  The draft application  makes no attempt to
specify storage locations and instead relies  upon  incompatibility
charts (given at the end of the application)  to determine storage
locations.  These charts should be used only  as guides.

SECTION B

1.  (B-2) The topographic map to be used at the site  should  be  at
a scale of 1" = 200 ft (or smaller) with contour  intervals of -
two feet and  include a site-wide map of greater scale  such as a
USGS quadrangle map.  A map which shows land  use  (especially
residential)  within 1000 feet of the hazardous waste  storage
facility (HWSF) should also be included.  Remember, the facility
is defined by the continuous boundary as defined  in 40 CFR 260.10.

2.  (B-2a(l)  and B-2a(2)) Maps:  show location of  HWSF on map of
the entire military base and show legal boundaries of  the base.

3.  (B-2a(4)) Show access control on "Map 1"  and  refer to B-2 of
the application.

4.  (B-2a(ll)) List fire equipment that will  be available for
use at the facility.

-------
                              - 2 -
 5.   (3-2a{12)&(13)) One topographical  map  should show  100 year
 Eloodplain  (if  one exists within  1000  feet of  the HWSF) and'
 drainage and any surface water bodies  around the HWSF.

 6.   (3-4) Tell  where off-site wastes come  from and what route(s)
 they will travel to jet to  the HWSF  from the port, airport, or
 state  line.  You will need  this information for the general
 public.

 7.   (3-4d)  Give the expected traffic load  as well as the load
 bearing capacity of the roads.

 8.   (Section B) Although not specifically  required we  suggest:
 (1) Each map contains a notation  in brackets indicating the map's
 date and orientation; (2) the 100-year  floodplain be discussed,
 whether the HWSF is in it or not;  (3)  seismic  considerations be
 provided; and  (4) certification of all  design  drawings, specifica-
 tions, and  engineering studies by  a registered professional
 engineer be noted.

 SECTION C

 1.   (p.C-1, 8th line) Regarding the phrase "on-base versus off-
-base", more information on  the source  of waste should  be provided.
 If wastes are coming from certain  off-site facilities  on a regular
 basis, their location and mode of  transportation should be
 described.  The permit will require proper manifesting for  these
 shipments.  Also, if shipments originate outside the continental
 U.S.,  this  should be described.  The information .should indicate
 if unexploded ordinance (VXO's) or outdated munitions  will be
 stored at the  facility.  Information of this "nature must be
 available for  the public hearing.

 2.   (C-l) A detailed physical and  chemical analysis of each
 hazardous waste must be obtained prior  to  storage of the waste.
 Reliance on generic chemical classification data is not adequate
 for this purpose.

     Physical analyses and  ranges  in the concentrations of chemical
 constituents need to be provided  for both  groups of wastes  (i.e.,
 Groups I and II).  With regard to  Group I  wastes, the  information
 provided by the container label and the applicant's Figure C-l
 (Disposal Turn-In Document  for Generators  of Hazardous Waste) does
 not appear  to be adequate.  Although the applicant may, indeed,
 rely on information provided by the generator, relying on what
 appears to  be  inadequate information is not appropriate for demon-
 strating compliance with 40 CFR 270.14(b)(2).  A more  complete
 physical and chemical description  of the waste must be provided.
 These  analyses  must provide sufficient  information on  the wastes'
 properties  to comply with 40 CFR 264.13(a).

-------
                              - 3 -
     With regard to the identification of Group I wastes, it
appears that too much reliance has been placed on the information
provided by the generator.  It is our opinion that there is no
guarantee that wastes in "original containers" will match the
label shown on the container.   This group of wastes should be
tested to assure proper identification.

     At a minimum, list what hazardous wastes, if any,  will not be
accepted (e.g., dioxins, nerve agents, etc.) and waste properties
which, if exhibited by the waste, would preclude the facility's
acceptance of the waste.  Also, it would help to refer to Appen-
dixes C-l and C-2 in this section of the application.

3.  (C-2) The waste analysis plan drew alot of comment from the
EPA/State workgroup.   Rather than attempt to combine all the
comments, I simply listed them out.  It will add greatly to
the readability of the model's waste analysis plan if all the
following are addressed.

**  The waste analysis plan must include provisions for repeating
chemical analysis as necessary to ensure that it is accurate and
up to date for waste generated on-site.

**  The waste analysis plan must specify procedures which will
be used to inspect and, if necessary, analyze each movement of
hazardous waste received at the facility to ensure it matches
the identity of the waste designated on the accompanying shipping
ticket.  Such inspection and/or analysis procedures must include
testing for indicator or fingerprint parameters which will provide
reliable evidence that the waste received is the same as the
waste represented.  Also, the waste analysis plan needs to specify:

     - the rationale for the selection of the parameters for
     which hazardous waste will be analyzed, in order to
     show how analysis for these parameters will provide
     reliable evidence that the waste received is the same
     as the waste represented;

     - the test methods which will be used to test for these
     parameters; and

     - the sampling method which will be used to obtain a
     representative sample of the waste to be identified.

The information requirements [under 40 CFR 270.14(b)(3 ) ] spelled
out above apply to deficiencies in the model application with
regard to Group I and II wastes.  Group II waste analytical
parameters need to be supplemented and/or the rationale for the
selection of the given parameters (i.e., Table C-l of the model
application) needs to be explained.  Of course, each movement or
shipment of hazardous waste received at the facility needs to be
tested at the time of receipt, regardless of the frequency of
such shipments.

-------
                              - 4 -
**  In regard to the waste analysis plan,, as long as the generator
is required to obtain a detailed chemical analysis,  then the
confirmation analysis done at the DOD storage facility should
ensure that the proper waste has been received.

**  The identity of wastes -generator both on-site and off-site
must be verified through the waste analysis plan.  Since the
DRMO is merely a tenant on the military base, it has very little
(if any) control over how wastes are handled on base, and it
should treat wastes from the host base and from other bases the
same.

**  DRMO does not control what happens on base;  it is merely a
tenant.  We see no basis for treating off-base and on-base wastes
differently under the wasta analysis plan.  Quite the contrary,
our experience has been that, perhaps due to the rapid turnover
of military personnel, it is very difficult to ensure proper
waste handling, even on the most environmentally concerned bases.
This Region will require -testing of both on-base and off-base
wastes, as it does for other commercial facilities.   The waste
analysis plan for DRMO storage facilities should also address
obtaining the information needed for final disposition of the
waste.   For example,  wastes that are restricted from landfilling
must be identified.  Each of the military sites sending waste to
DRMO will not be keeping abreast of the land disposal restrictions,
waste oil rules, etc., and properly labeling its waste/ therefore,
DRMO should establish procedures for identifying, labeling, and
properly disposing of these wastes.

**  In section C-2 (waste analysis plan), on the third line, the
term "indicates" is questioned.  (40 CFR 264.13(a)(2) says "may
include data".)  This seems to be the arguement for not completing
a detailed chemical and physical analysis of the waste as required
in §264.13(a ) (1) .  This analysis must contain all the information
necessary to treat, store, or dispose of the waste.

**  Attached to these comments is a "Sample Waste Analysis Plan"
which Region 3 believes a good guide in revising the model.

4.  (C-3c) See our comment on the waste analysis plan above.
Also,  see the attached "Sample Waste Analysis Plan for guide.

5.  (C-3c(D) The parameters and rationale section must include a
list of parameters for which each hazardous waste will be analyzed
and trie rationale for the selection of these parameters.

6.  (C-3c(D) In the case of waste not meeting the generators
identification, the waste should be returned to the generator.

7.  (C-3c(2)) The test method to be used to analyze each parameter
must be specified.

-------
                               - 5 -
 8.  (Table C-l, p.C-11) The range of values for either acceptance
 or rejection for each of the analytical parameters should be
 stated with accompanying rationale.  Further,  color and physical
 state should be used.  See attached "Waste Analysis Plan" spot
 check procedure for example.

 9.  (C-3c(3)) Sampling methods must also be specified for those
 wastes listed in Appendix C-l.

10.  (C-3c(4)) Table C-4 should be clarified and expanded.  "Shipment
 size" evidently refers to the number of 55-gallon drums - - this
 should be clarified.  Also, give sample frequency for other type.si.;_^
 of containers.                                                  ..  • •

11.  (C-3c(4)) Describe the procedure used to determine which drums
 in a shipment would be sampled.

12.  (C-3c(4)) The first line should read:  "Frequency of analysis
 by the generator will be 'as follows:".   Also,  the phrase in
 bullet #2, "will be performed at each turn-in" should be changed
 to "will be performed prior to turn-in."
                                                                =.«^

13.  (Bottom of page C-12) What does the footnote "*" reference?

 ment Printing Office, Washington, D.C.   20401, (202)783-3228.
 If you choose to use the original footnote, you should state
 "second Edition, as updated" and we are the "Office of Solid

 three lines should be change to:

16.  (C-3c(5)) Certifications and documentations of quality control
 and quality assurance procedures should be maintained in the
 "operating record".

17.  (C-4) Refer to Appendices D-2 and F-2 and give examples of
 how incompatible wastes will be identified upon receipt.  Will
 different storage areas be designated for different types of
 wastes?  If so, tell how.  If not, tell how the workers will keep
 track of where each category of wastes is stored in the HWSF.

-------
                               - 6 -
18.   (C-4)  The permit application seems to ignore that all flam-
 mable s are not compatible,  just as all acids are not compatible.
 Further designation of incompatiblity is necessary.   The^appli-
 cation should not be written for every hazardous waste.   The
 applicant  should have a log which indicates what hazardous waste
 have been  stored in the past,  and should project as  exactly as
 possible,  what waste will be stored in the future.   If the
 applicant  insists that all waste codes be allowed,  then the
 design of  the storage bays must be sufficient to separate all
 incompatible wastes.

19.   The Waste Analysis Plan must state what actions  will be taken
 when a waste differs from its  label description, and what will
 be  done with unknown wastes when they arrive.

 SECTION D

 1.   (D-la) We did not receive  enough information on  the loading
 area sump  design to approve it.  In general, we find its con-
 nection to the storm drainage  system worrisome.  Also, we have
 found that sumps, even when covered by a roof,  fill  quickly with
 rainwater.  The procedures for maintaining the sump  and keeping
 it  free of storm water are of  great importance and  must be docu-
 mented clearly and carefully.

 2.   (D-la(l)) See our comment  to "Section A".

 3.   (D-la(l)) Experience has shown that application  of epoxy
 coatings to concrete under suboptimal weather conditions has
 resulted in peeling of the coating layers.   DLA may  want to
 protect itself from costly repairs by preparing a thorough QA/QC
 plan for application of the coatings.

 4.   (D-la(l)) Referring to "Conforming Storage Facility Standard
 Design", 3/86,  Section E,  Figure 24,  it is suggested to (1) add
 a six inch floor thickness dimension, (2) correcting the depressed
 floor dimension on left side of wall to "Face to Face",  not "Face
 to  Center  Line",  and (3) changing the depressed floor height
 dimension  from "6-8 inches" to "varies: 4" minimum".

 5.   (D-la(l)) Information showing the basic design parameters,
 dimensions,  and materials of construction of the catch basin
 adjoining  the load/unload area needs to be provided.  The materials
 of  construction of the catch basin should also include the same
 barriers to waste migration that will be provided for the interior
 storage area and the load/unload area (i.e., vapor- barrier and
 epoxy sealant).

  6.   (D-la(l))  Within the discussion, epoxy coatings to be applied
 on  concrete, curbs and partition walls, and the polypropylene
 water stops and other joint sealers,  must be compatible with the
 waste.  The specifications for the coatings and joint sealers,
 plus,  discussion of compatibility with'the waste, must be supplied.

-------
 7.  (page D-3) The use of the phrase "perimeter curb" in the third
 paragraph does not match the design.  Shouldn't the phrase be
 "depressed section".

 3.  (D-la(D) Revise page D-3 to state that the storage area will
 be designed to contain the greater of 10 percent of the total
 volume of containers or all of the volume of the largest container.
 Submit calculations demonstrating the containment system's ability
 to hold the required volume.  Thus, it can be seen that the
 model application needs to be revised in the area referring to.
 "...25 percent of the volume of the largest container...".

 9.  (D-la(2)) With regard to a description of how the design
 promotes drainage or how the containers are kept from contact
 with standing liquids in the containment system, the model
 application does not offer adequate description because of state-
 ments such as:  "storage aids can be racks, shelves..." and
 "shelving. . .can also be installed..."  (emphasis added).  More
 positive statements need to be included, and these statements
 must take into account all storage areas.

10.  (D-la{3)) Regarding spills, on page D-4, the statement is -•"•.„-.
 made that a 4 inch curb will be able to contain .any spiLts:;". TheV
 facility is instructed to include site specific calculatians;.  ^  '» :
 However, if the area contains 55-gallon drums,  stacked 4 to a    '-'';
 pallet,  and 3 pallets high,  the capacity to hold 10 percent of
 the volume may not be met.  Also, the phrase "4-inch curbing"
 should be changed to "a 4 inch depressed area".

11.  (D-la(4)) The PAT's concern about the adequacy of the loading
 area sump is well-founded.  We did not receive enough information
 to calculate run-off into the sump, nor was the volume of the
 sump given in the material we reviewed.  We would like to see
 more detail on the outlet valve to the storm drainage system,
 also,  the potential for operator error seems quite high, even
 with the alarm.

12.  (D-la(4)) The application says a "sealed concrete spill con-
 tainment area" is provided outside.  How will the concrete be
 sealed?  Specifications?  Chemical compatibility?  Further, will
 the loading/unloading area be swept/or washed after material
 has been transferred and prior to reopening the valve in order
 to prevent a release to surface water?  When the valve is closed,
 will it be tagged with a tamper seal to prevent reopening prior
 to completion of the .transfer activity?

13.  (D-la(5)) Add after the first sentence:  "A wash with an
 apropriate solvent or detergent will follow to assure decon-
 tamination. "

-------
                               - a -
14.  (D-la(5)) On page 9, there is a list for spill response equip-
 ment and personnel protective equipment.  The items listed are
 not appropriate for all the different chemicals that will be
 handled at the facility.  For example, many of the chemicals
 listed are incompatible with rubber.  Also, there is no mention
 of pumps being available for collecting spills,  yet on page D-5,
 the use of a pump is mentioned.   THE PERMIT APPLICATION.MUST BE
 CONSISTENT.

      On page D-5,  pumping the spilled liquid is one of the
 alternatives to use for clean-up.  However, because the contain-
 ment area is not sloped, it will be almost impossible to pump any
 liquid.  For example,  from dimensions estimated from the enclosed
 drawings,  if the containment area is 10 feet by 4 feet, then a
 spill Crom one 55 gallon drum will be approximately two inches
 in depth.   Pumping such a spill would be difficult.   It would
 facilitate spill clean-ups if the containment area were sloped
 to a collection sump.

15.  (D-lb(2)) The applicant has misinterpreted the requirement.
 The applicant must show that after a spill occurs, the containers
 will not be in contact with the spilled material...

16.  (D-lc) See our comment #18 in^.Seetiarr.Cr above.•"• Regarding
 bullet #2  on page D-6, the site specific information should provide
 more detail on how incompatible wastes will be separated.  The
 "storage plan" in Figure D-2 should be annotated to correspond
 to the incompatibility groups (i.e., Group 1-A,  Group 1-B, etc.).
 The permit reviewer should be shown how the waste will be separ-
 ated.   For example, how will Group 4-A wastes be prevented from
 contacting Group 3-A wastes both of which may be stored in the
 "toxic" area.  The applicant should beware of the use of a common
 sump for incompatible waste.

17.  (D-lc) Is it possible to operate the electric roll-up doors
 manually?   This will be necessary in case of a power outage.
 Further, regarding the "storage according to compatibility" and
 considering the size of the lists in Appendixes C-l and C-2,
 will the storage building be big enough to provide segregated
 cells to store separately incompatible wastes.

18.  (D-ld) Each DRMO permit application must give specific
 (1) procedures for transporting containers (of all types, e.g.,
 some may not be moveable by forklift) across the facility,
 (2) aisle  spacing to be maintained, (3) maximum number of drums
 and other  containers,  and (4) maximum stacking height in each
 area in which containers are stored.

-------
                              - 9 -
    Also, the application should demonstrate that adequate space
and equipment are available for transferring waste from damaged
containers to new ones.  This should be done near a well ventilated
area equipped with shower, eye-wash, alarm, sump, and a place to
store new drums/containers.   Transferring wastes will present
the Largest potential safety problem of all the HWSF operations,
and it should be addressed in the application.

SECTION F

1.  (F-la(2)(b)) With regard to the means used to control entry
pursuant to 40 CFR 264.14(b)(2)(ii), it should be pointed out
that Air Force Base Security Police may not be available for any
DRMS facilities that are physically located off the site of the
Air Force Base.  In such cases, the application should provide
site-specific information as to how the owner or operator will
comply with 40 CFR 264.14(b).

2.  (F-la(3)) The warning signs referred to in Section F-la(3)") *
of the model application must be posted not only at the entrances
to the active portion of the facility, but also at other locations,
in sufficient numbers to be seen from any approach to the facility,
pursuant to 40 CFR 264.14(c).                             "":"
3...  (F-2) The inspection tables are very good.  Our only comments
are that (1) most of the items on Table F-2 should be done daily"
when loading/unloading, and (2) the problem to look for when
inspecting container labels is whether the labels are intact.

4.  (Table F-l) The General Inspection Schedule should include
"smoke detectors" and "lighting & power equipment" and "snow &
ice removal from areas traveled by vehicles (applicable in some
States) under the "Safety and Emergency Equipment" headings.

     Under the heading "Operating and Structural Equipment",
direct reference should be made to inspect the valve closing
"catch basin" drain system, as well as, the warning siren weekly
or daily if loading/unloading.

5.  (Table F-2) Include an inspection of the containment systems
for both the loading/unloading area and the container storage areas
to detect the presence of accumulated liquids in the inspection
schedule.  Also, inspection of any piping and associated ancillery
equipment should be performed regularly.

6.  (F-2c) Does the inspector have authority to commit government
resources to undertake the necessary remedial action?

7.  (F-2d) The inspection log should also note the time of
inspection.

-------
                               - 10 -



 8.   (F-3(a)(3)  and others) A contingency plan is  not included.
 Each facility is to include its own contingency plan.   However,
 if  the building is constructed on a consistent basis,  then expect
 for a list of emergency coordinators,  the plan should  be  the
 same for each site.   Remember,  the contingency plan must  address
 whether the drums will be moved prior  to initiation of the
 clean-up and to where they will be moved.

 9.   (F-3b) How  hard will it be to get  a drum from a pallet into a
 hand truck?

10.   (F-5a) The  use of brass instruments is mentioned in handling
 ignitable waste.  The applicant should be aware that the  reaction
 of  1,1,1-trichloroethane and brass products produces a neuro-
 toxic agent.

11.   (F-5b) See  our comment #18 in Section C above.

 SECTION H

 1.   (H-l) The model application should demonstrate, pursuant  to
 40  CFR 264.16(a)(2)  that the personnel training program is directed
 by  a person trained in hazardous waste management procedures.
 Perhaps it could be noted in the model application that this
 demonstration will be made as part of  the site-specific portion
 of  the application.

 SECTION I

 1.   (I-la) What parameters will be used to properly close the
 facilities.  What decontamination levels will be  used.  What
 tests will be performed to determine if decontamination has been
 achieved.  The  closure performance standard must  match the
 requirement of  40 CFR 264.111.

 2.   (I-ld) Final closure must also be  certified by the owner/
 operator.  In regard to initiating final closure,  40 CFR 264.113
 states final closure activities will be initiated upon receipt
 of  the final volume of hazardous waste.  So,  the  first sentence
 of  the 3rd paragraph should read: "Upon receipt of the final
 volume of hazardous waste, final closure will be  initiated (see
 Table 1-1 on page 1-3)."

 3.   (I-le) The  procedure given in Section I-le of the  model
 application to  demonstrate removal of  all hazardous waste and
 residues needs  to be supplemented or clarified in the  following
 area:   "...washings and collection of  wash residue...will be
 performed until an analysis of the wash residue from all  affected
 surfaces indicates that the level of contamination is  within
 regulated concentrations."  The meaning of "regulated  concentra-
 tions" is not clear.  Such washings should be performed until an
 analysis of the wash residue from all  affected surfaces indicates
 no  significant  contamination relative  to the wash material prior
 to  being used.

-------
     Furthermore, any contaminated soil or groundwater must be
removed or treated down to the level of background concentration
for each Appendix VIII hazardous constituent which is reasonable
expected to have been present in any of the waste handled at the
facility.

     The decontamination procedure for the container storage
area should describe the specific analysis to be conducted for
each type of waste stored.  The definition of clean up to
"regulated concentrations" should be provided.   Is the loading/
unloading area's "catch basin" included in this section; if
not, is it included elsewhere in the Closure Plan?

4.   Per the reference to SE-846 at the bottom of page 1-5, see our
comment #13 in Section C.

5.   The last paragraph on page 1-5 (regarding soil sampling) is
meaningless.  Soil samples must be taken any time a spill reaches
the ground surrounding the facility, because contamination left
in the soil constitutes i-llegal disposal.   I_f further sampling
will be done at closure, the closure plan should give the number
of samples, sample locations and methods,  types of analyses, and
detection levels to be achieved.                                ;;':
                                                                '-fc'- •
CORRECTIVE ACTION FOR SOLID WASTE MANAGEMENT UNITS           ,,' •,'"

     The model application does not instruct the DRMOs that all
solid waste management units at the base must be identified and
appropriate corrective action taken.  If an installation assessment
report has been prepared for the base under the Installation
Restoration Program, this report may be useful in satisfying the
Section 3004(u) of RCRA information requirements.  (See the
attached "RCRA Facility Assessment Guidance Manual" for further
information.)

APPENDIX C-l

     Appendix C-l and C-2 do not include "K" waste.  Perhaps "K"
wastes were not included because they are specific to certain
industries, which would not include military installations?

                      Wastft Ana lysis  Plan
 A  proposed waste  stream  from  a  new  or  existing  customer  (the  generator)


 is   evaluated  for  its  economic  value by  McKesson  Envirosystems  and  a


 purchase agreement  is  completed between  McKesson  Chemical  Company and


 the  customer.  A  sample  is  then submittiu   by way of  McKesson Chemical


 to McKesson Envi rosystems for appropriate  analyses.   The parameters-..:.  '


 measured vary  from waste stream to  waste stream;  examples  of  the major


 parameters needed by the recycler and  the  rationale for  their selection
        t

 appear  in the appended table.




 The  results of these analyses are reported  on a "Results of Laboratory


 Analysis" form, a copy of which follows: a  copy of the completed form


 is sent to the McKesson Chemical branch  prior to  the  branch's sending


 a truck Co bring the drums of spent soKent back  to Che branch.




 These physical and chemical  analyses of  each waste stream  will  be


 repeated when:


     1.  It is necessary to ensure  that  they are  accurate  and up-to-date.


     2.  The branch is notified, or has  reason to believe, that the


         process of operation generating the hazardous waste  has changed.


     3-  A manifest discrepancy is detected (unless the branch  chooses


         to return the shipment to  the generator).


Ac laast annually, McKesson  Chemical Company will either determine  the

 physical  and  chemical  parameters  referred  to in  the  appended  table

 or receive  certification front the.gsnerator  of each  specific  waste

 that these  parameters  remain  as previously measured.   Such  certification

 will  be  kept  as  part of the operating  record.  (In fact,  all  shipments

 of drums  received  at McKesson  Envirosystems  are  routinely analyzed  in

 order that  their economic value is known (i.e.,  to determine  how much

 credit to issue  to the generator)).


 Upon  receipt of  these drums of solvent, the  McKesson Chemical branch

 has  the responsibility of measuring a  sufficient number of  paramenters

 to assure the branch that the customer did indeed send what he had

 agreed to.  This consideration leads to the  selection of  "fingerprint"

 or spot check parameters,  the measurement of which will provide reasonable

 assurance to the branch that the drums of spent solvent received from a

 generator actually contain  what* :he customer agreed to subnit as

 established by the analysis by M:Kesson Envirosystems of  the  corres-

 ponding sample.   In addition co comparing the information on  the manifest

 as to number of  drums and  their contents as defined on the hazardous

waste labels,  the following physical  data will be determined  at the branch

on samples taken from an appropriate number of drums  from each waste

 stream:

       1.   Physical state of the spent solvent,  including phase separa-

           tion  and presence of solid material.

 number.   Each separate  sample will  be analysed for the "fingerprint"

 parameters  — physical  state, color and specific gravity.


 The methods of analysis  for the "fingerprint" parameters are  described

 below:

       1.  Physical state, phase  separation and presence of solid

           material will be determined by observation.

       2.  Specific gravity will  be determined by ASTM Method 02111-71

            (reapproved  1978).  However, if the specific  gravity of

           Che wa.  te is  less Ckan 0.9 (at 25°C)., an  appropriate ASTM

           standard method using  hydrometers will be used.

       3.  The determination of color (or hue) of the waste,  as received,

           wiM  be made by placing a sample into a glass  test tube  and

           comparing the color to a group of knowncolors.  The six  e<» .  116)

           possible color choices are colorless, white,  brown, black,

           yellow, yellow-green, green, blue-green, blue, blue-violet,

           violet, red-violet, red, red-orange, orange,  and orange-yellow.

           Lighter ir.ensities of a color (equivalent to mixtures of the

           color with white)  are considered for these purposes to be the

           named color.

 compared to  the values  obtained*^  the jnitial McKesson  analysis.   If  any


 sample fails  any of the spot  check  criteria, all  containers of  that waste

 must be  returned to the generator except those containers  that  pass all of

 the  "fingerprint"  criteria.



 The  criteria  for the color spot check are that for a waste that should be


 colorless, wh;:^,  brown,  or black, the waste must  be that color  to pass the


 test.   If a waste  should  be any of  the other twelve named colors, the  spot


 check  sample n.ust  be the  original color or no more than one color removed

 from  the original  color when  using  a color wheel  (e.g. Grumbacher Cc'-""

 Compass) to pass the test.



 The criteria for specific gravity is that the measured specific cravity


 at 25°C must ts within 0.10 of the originally determined specific gravicy
                                  •v
 to pass  the ttst.



All these data and  observations will be recorded at the branch and maintained


as part of tne branch's operating record.

Uniform Requirements for Sample Taking
Personnel Safety Precautions
Prior to opening the container for sample withdrawal,  the employee
who is to do the sampling must be wearing his hardhat, his safety
glasses, and his solvent*impervious gloves.

The equipment required in order to obtain a sample consists of:
  • A Coliwasa type sampling tube.
  - A clean, dry glass sample bottle.
  - A screw-cap for*the sample bottle which is fitted  with a poly-
    ethylene poly-cone seal.
  - A label containing the following information:
      - The manifest number corresponding to the waste shipment.
      - The name of the waste being sampled.
      ^-The date on which th* sample is taken.
      - The name of the employee withdrawing the sample.
CAUTION:  Always leave about one-inch of free  space in the sampls
bottle before it is closed.  Never  fill  the  sample bottler to the
brim.  Quite frequently the sample  is withdrawn at a temperature
which is less than the temperature  in which  the sample will be
stored prior to analysis.  As the temperature  increases, the liqui
expands.  If the sample bottle is completely filled,, the expanding
liquid has no ^Jace to go and it will shatter  the bottle.

 Sampling Procedure  for Drums
                         .  *•*   f
   1.  Sampling is done through the bung on the drum.   When removing
      the bun? closure of the  drum, first loosen it slightly without
      completely removing the  bung in order to relieve any internal
      pressure which may have  been built up because of change in
      temperature.
   2.  After you are sure that  there is no pressure  in  the  drum,  remov
      the bung closure completely.
   3.  Open the bottom valve of the  Coliwasa type sampler completely.
   4.  Lower the sampler slowly into the drum until  the bottom of the
      sampler reaches the 'bottom of the' rf-'-um.
   5.  Close the bottom valve of   the Coliwasa type sampler completel
   6.  Withdraw the sampler from the container.
   7.  Transfer the content of  the  sampler to the sample bottle.
   8.  Screw the cap tightly onto the bottle.
   9.  Affix the appropriate label  to the  bottle.
 10.  Wipe any spillage from the outside  of the  bottle.
 11.  Clean the Coliwasa sampler prior to using  it  on  the  next drum.
 12.  Inspect the gasket on the drum closure  to  make sure  it  is  in
      good condition.
Disposition of the Sample
After the samples have been taken, the sampling containers closed, th
labels affixed,  and the sample containers wiped off, take the samples
to the laboratory and turn them ov«»r to the chemist for analysis.
