FROM:-     Don R, Clay
          Assistant AdmTnis

TO:       Regional Administrators,  Regions I-X

     This memorandum transmits  to you our "Final Guidance on
Administrative Records for Selecting CERCLA Response Actions."
This document replaces the "Interim Guidance on Administrative
Records for Selection of CERCLA Response Actions," previously
issued on Marsh. 1, 1989.

     The guidance sets forth  the policy and procedures governing
the compilation and establishment of administrative records for
selecting response actions under the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980 (CERCLA), as
amended by the Superfund Amendments and Reauthorization Act of
1986 (SARA).  This guidance is  also consistent with and expands
on Subpart I of the National  Oil and Hazardous Substances
Pollution Contingency Plan, 55  Fed.  Reg.  8859 (March 8, 1990).

     This «pai«Mstea reflects input received from the Regions,
Headquarters &a<3 the Department of  Justice.   There have been
several drafts of this guidance and comments have been
incorporated.  I thank you for  your assistance.

I.   INTRODUCTION

A.   Purpose and Scope of the Administrative Record

     This guidance addresses the establishment of administrative
records under Section 113 of the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980 (CERCLA),  as
amended by the Superfund Amendments and Reauthorization Act of
1986 (SARA).1   Section 113(k)(l)  of CERCLA requires  the
establishment of. administrative records upon which the President
shall base the selection of a response action (see Appendix A for
the complete statutory language).

     Chapter I of this guidance introduces the purpose and scope
of the administrative record.  Chapter II reviews procedures for
compiling and maintaining the administrative record.  Chapter III
examines the various types of documents which should be included
in the administrative record.  Chapter IV discusses how agencies
outside EPA are involved in establishing the record.  Finally,
this guidance includes a glossary of frequently used terms and
acronyms as well as several appendices.

     Although, this guidance is written for use by the United
States Environmental Protection Agency (EPA), it can be adapted
for use by state and federal agencies required to establish
administrative records for the selection of CERCLA response
actions.  As used in this guidance the term "lead agency" means
either EPA, a state or other federal agency, which is responsible
for compiling and maintaining the administrative record.  As used
in this guidance, the term "support agency" means the agency or
agencies which furnish necessary data to the lead agency, reviews
response data and documents and provides other assistance as
requested by the OSC or RPM.  This guidance reflects the
revisions to the National Oil and Hazardous Substances Pollution
Contingency Plan (NCP) published on March 8, 1990, 55 Fed. Reg.
8859 (see Appendices L and M).

     The administrative record established under Section 113(k)
of CERCLA serves two primary purposes.  First, the record
contains those documents which form the basis for selection of a
response action and under Section 113 (j), judicial review of any
issue concerning the adequacy of any response action is limited
to the record.  Second, Section 113(k) requires that the
administrative record act as a vehicle for public participation
     1  42 U.S.C.  §9613.   References  made  to  CERCLA  throughout
this memorandum should be interpreted as meaning "CERCLA, as
amended by SARA."

-------
                                   OSWER Directive No. 9833.3A-1

in selecting a response action.  This guidance document discusses
procedures developed to ensure that the lead agency's
administrative records meet these twin purposes.

     The administrative record is the body of documents that
"forms the basis" for the selection of a particular response at a
site.  This does not mean that documents which only support a
response decision are placed in the administrative record.
Documents which are included are relevant documents that were
relied upon in selecting the response action, as  well as relevant
documents that were considered but ultimately rejected (e.g.,
documents "considered or relied on") .

     This document uses the phrase "considered or railed on" in
discussing which documents should be included in  the
administrative record to indicate that it is EPA's general policy
to be inclusive for placing documents in the administrative
record.  However/ this term does not mean that drafts or internal
documents are normally included in the administrative record.
Lead or support agency draft or internal memoranda are generally
not included in the administrative record/ except in specific
circumstances (see section III.G. at page 33). Thus/ the record
will include final documents generated by the lead and support
agency/ as well as technical and site-specific information.
Information or comments submitted by the public or potentially
responsible parties (PRPs) during a public comment period (even
if the lead agency does not agree with the information or
comments) are also included in the administrative record (see
section III.D. at page 30).

     The following principles should be applied in establishing
administrative records:

o    The record should be compiled as documents relating to the
     selection of the response action are generated or received
     by the lead agency;

o    The record should include documents that form the basis for
     the decision, whether or not they support the response
     selection; and

o    The record should be a contemporaneous explanation of the
     basis] for the selection of a response action.

     The effort to establish adequate administrative records
encompasses a vast array of people including: Administrate
Record Coordinators, Remedial Project Managers (RPMs), On-Scene
Coordinators (OSCs), enforcement staff, records management staff,
Regional Counsel staff, Community Relations Coordinators (CRCs),
other federal agencies, states, CERCLA contractors, arid the

-------
                                   OSWER Directive No. 9833.3A-1

public.2  This guidance will  discuss  the roles  and
responsibilities of these people and how they interact with one
another.

B.   Judicial Review

     Section 113(j)(l) of CERCLA provides that judicial review of
any issues concerning the adequacy of any response action shall
be limited to the administrative record.

     Judicial review based on an administrative record provides
numerous benefits.  Under Section 113(j) of CERCLA and general
principles of administrative law, when the trial court reviews
the response action selected, the court is limited to reviewing
the documents in the administrative record.  As a result, facts
or arguments related to the response action that challenging
parties present for the first time in court will not be
considered.

     Record review saves time by limiting the scope of trials,
thereby saving the lead agency's resources for cleanup rather
than litigation. -Courts will not allow a party challenging a-J
decision to use discovery, hearings,  or additional fact finding
to look beyond the lead agency's administrative record, except in
very limited circumstances.  In particular, courts generally will
not—permirfe persons -challenging -a-response-decision--to-depose-,-—-——
examine, or cross-examine EPA, state or other federal agency
decisionmakers, staff, or contractors concerning the selection of
the response action.

     Furthermore, the administrative record may be cited long
after officials responsible for the response decisions have moved
into different positions or have left the lead or support agency.
Judicial review limited to the record saves time involved in
locating former employees who may not remember the facts and
circumstances underlying decisions made at a much earlier time.

     Moreover, in ruling on challenges to the response action
decision, the court will apply the highly deferential "arbitrary
and capricious" standard of review set forth in Section 113(j) (2)
of CERCLA.  Under this standard, a court does not substitute its
judgment for that of the decisionmaker.  The reviewing court does
not act as an independent decisionmaker, but rather acts as a
reviewing body whose limited task is to check for arbitrary and
capricious action.  Thus, the court will only overturn the
response selection decision if it can be shown on the
     2 As  used  hereinafter  in  this guidance  the term  "public"
includes potentially responsible parties (PRPs).

-------
                                   OSWER Directive No. 9833.3A-1

administrative record, that the decision was arbitrary and
capricious or otherwise not in accordance with the law.  However,
the extent to which EPA benefits from having judicial review
limited to the record depends on the quality and completeness of
each record.

C.  Publir    cicipation

     Section 113(k)(2) of CERCLA requires that the public have
the opportunity to participate in developing the administrative
record for response selection.  Section 117 of CERCLA also
includes provisions for public participation in the remedial
action selection process.   Both sections  reflect a statutory
emphasis on public participation.  Participation by interested
persons will ensure that the lead agency has considered the
concerns of the public, including PRPs, during the response
selection process.  In addition, for purposes of administrative
and judicial review,  the record will contain documents that
reflect the participation of the public and the lead agency's
consideration of the public's concerns.

     If the lead agency does not provide an opportunity for
involvement of interested parties in the development of the
administrative record, persons challenging a response action may
argue that judicial review should not be limited to the record.
The lead agency must, therefore, make the information considered
or relied on in selecting a response action available to the
public, provide an appropriate opportunity for public comment on
this information, place comments and information received from
the public in the record, and reflect in the record the lead
agency's consideration of this information.

II.f  PROCEDURES FOR ESTABLISHING THE ADMINISTRATIVE RECORD

A.   Administrative Record Coordinator

     Each region should have an Administrative Record
Coordinator.  The Record Coordinator generally has the duty of
ensuring that the administrative record files are compiled and
maintained according to Subpart I of the NCP and this guidance/
     3 42 U.S.C.  §9617.

     4 The "administrative record file"  should be distinguished
from the "administrative record."  The administrative record file
refers to the documents as they are being compiled.  Until a
response action decision has been selected, there is no complete
administrative record for that decision.  Thus, to avoid creating
the impression that the record is complete at any time prior to

-------
                                   OSWER Directive No.. 9833.3A-1

The Record Coordinator will not be responsible for deciding which'
documents are included in a record file.  Those decisions should
be made by the OSC or RPM, with appropriate consultation of ORC
staff.  The Record Coordinator's duties ordinarily include:

o    Developing procedures for creating record files;

o    Ensuring that the public is notified that the record files
     are available for inspection;

o    Ensuring that the records are available at or near the site;

o    Ensuring that the records are available at the regional
     office or other central location;

o    Coordinating efforts to obtain the necessary documents;

o    Indexing the record files;

o    Updating the record files and indices on a regular basis
     (e.g.,  quarterly);

o    Ensuring availability of the record file for copying;

o    Ensuring that sampling and testing data, quality control and
     quality assurance documentation, and chain of custody forms
     are available for public inspection, possibly at a location
     other than that of the record files;

o    Coordinating with ORC staff on questions of relevance and
     confidentiality of documents submitted for the record files;

o    Arranging for production and presentation of the record to
     court when necessary for judicial review;

o    Maintaining the confidential portion of the record files, if
     necessary;

o    Maintaining the "Compendium of CERCLA Response Selection
     Guidance Documents";

o    Coordinating with states and federal agencies on record
     files compiled by them;  and
the final selection decision, the set of documents is referred to
as the administrative record file rather than the administrative
record.

-------
                                   OSWER Directive No. 9833.3A-1

o    Notifying appropriate personnel of the timing for review of
     state and federal record files.

Appendix D contains a model position description for an
Administrative Record Coordinator.

     The Record Coordinator must work closely with RPMs, OSCs,
enforcement staff, records management staff, Regional Counsel
staff, community relations staff, and the Department of Justice
(DOJ)  (for cases in litigation).

     If the way the record was  compiled and maintained is
questioned in litigation, the Record Coordinator may be called
upon to prepare an affidavit or testify about those procedures.
Therefore, the Record Coordinator should be familiar with the
procedures associated with the  record, and be qualified to
fulfill the responsibilities outlined above.

B.   Multiple Response Actions

     In general, every decision document (e.g., Record of
Decision (ROD) or Action Memorandum) must be supported by an  "
administrative record.  Under CERCLA, cleanups are often broken
up into distinct response actions.  At a given site this may
include several removal actions, and/or remedial actions known as
operable units.  For every removal action or operable unit, a
separate administrative record  must be compiled.

     Information relevant to more than one response decision,
such as a site inspection report or a preliminary assessment
report may be placed in the record file for an initial response
action and incorporated by reference in the indexes of subsequent
record files for that site.

C.   Compilation

     The administrative record  file should be compiled as
relevant documents on the response action are generated or
received.  Thus, all documents  which are clearly relevant and
non-privileged should be placed in the record file, entered into
the index, and made available to the public as soon as possible.
For exavple, the remedial investigation/feasibility study (RI/FS)
work plan, summaries of quality assured data, the RI/FS released
for public comment, the proposed plan, and any public comments
received on the RI/FS and proposed plan should be placed in the
record file as soon as they are generated or received.

     When there are questions whether particular documents should
be included in the record file, such documents can be segregated
and reviewed at regular intervals (e.g., quarterly).   For

                                6

-------
                                   OSWER Directive No.- 9833.3A-1

example, draft documents or documents subject to claims of
privilege should be set aside for review by ORC and other
appropriate staff.  At critical times, such as prior to the
public comment period, the issues regarding these documents
should be completely resolved and the documents included in the
record file, if appropriate.

     The record file should be updated while it is available for
public inspection.  The additional documents should be placed in
the record file and entered in the index.  Any updates to the
record file should be made to all copies of the record file.

     All documents considered or relied on in selecting the
response action should be in the record file when a decision
document (e.g., a record of decision) is signed.  Documents
relevant to the response selection but generated or received
after the decision document is signed should be placed^in a post-
decision document file and may be added to the administrative
record file in certain circumstances  (see section III.N. at page
40) .

D.   Index

     Each administrative record file must be indexed.  The index
plays a key role in enabling both lead agency staff and members
of the public to help locate and retrieve documents included in
the record file.  In addition, the index can be used for public
information purposes or identifying documents located elsewhere,
such as those included in the compendium of guidance documents
(see Appendix E).  The index also serves as an overview of the
history of the response action at the site.

     The index also provides the lead agency with a degree of
control over documents located at or near the site.  The creation
of an index will prevent persons from altering the record simply
by physically adding or removing documents from the record file.

     The index should include the following information for each
document:

o    DocuMnt Number;

o    DocuMnt Date - date on the document;

o    Document Title - one or two line identification.  Identify
     the actual document, not a transmittal memo or other less
     relevant document.  Include sufficient information so the
     document cannot be confused with another (e.g., the title
     "report" may be insufficient);

-------
                                   OSWER Directive No. 9833.3A-1

o    Author - Name and affiliation;

o    Recipient - Name and affiliation; and

o    Document Location.

     The index can be organized either by subject or in
chronological order.  If documents are customarily grouped
together, as with sampling data and chain of custody documents,
they may be listed as a group in the index to the administrative
record file.  Appendix C contains a model index organized by
subject.  Computer databases have been helpful in generating and
updating the index.

     The index should be updated when the record file is updated.
It is preferable to update the record file when documents are
received, or at least quarterly.  Such updates should coincide
with the periodic updating of the record file and review of
material for which there are questions about relevance or
privilege (see section II.C. at page 6).  The index .iould also
be updated before any public comment period commence-.  The index
should be labeled "draft index" until all relevant documents are
placed in the record file.  When the decision document is signed,
the draft index should be updated and labeled "index.11

E.   Location

E.I. General

     Section 113(k)(l) of CERCLA requires that the administrative
record be available to the public "at or near the facility at
issue."   Duplicates of the record file  may be kept  at any other
location.  A copy of the record file must be located at the
regional office or other central location.  Both copies of the
record file should be available for public inspection at
reasonable times (e.g., 9-4, Monday-Friday).  In the case of an
emergency removal, unless requested, the record file needs to be
available for public inspection only at the central location (see
section II.F.3. at page 14).

     The record file located at or near the site should be placed
in one of th« information repositories which may already exist
for community relations purposes.  These are typically located in
a library, town hall, or other publicly accessible place.  If
there is no existing information repository, or if the repository
     5 See 40 C.F.R.  §300.805.

                                   OSWER Directive No.. 9833.3A-1

does riot have sufficient space for the record file, any other
publicly accessible place may be chosen to house the record
file.   When a Superfund site is located  at  or  near an Indian
reservation, the centrally located copy of the record file may be
located at the Indian tribal headquarters.  The Community
Relations Coordinator (CRC) should be consulted on the location
of the information repository and record file.

     The record file should be transmitted to the local
repository in coordination with the CRC.   The CRC should make the
initial contact to establish the local repository and request
housing for the record file.  The Record Coordinator should make
arrangements for delivering the record file to the local
repository.

     The record file should include an introductory cover letter
addressed to the librarian or repository manager (see Appendix
F) .   In addition, a transmittal acknowledgement form should be
included to ensure receipt of the record file (see Appendix G).
Finally, an administrative record fact sheet should accompany the
record to answer questions from the public (see Appendix H).
Updates to the record file should be handled in a similar fashion
(see section II.C. at page 6).

     In addition to the publicly available record file, if
feasible, a master copy of the record file should be kept at the
regional office or other central location of the lead agency.  To
preserve the integrity of the master copy of the record file, it
should not be accessible to the public.  If not feasible to
establish a master copy, the lead agency will need to establish
an effective security system for the publicly available record
file.  The master copy of the record file may be maintained in
microform to conserve storage space (see section II.J. at page
21).

E.2. Special Documents

     Certain documents which are included in the record file do
not have to be maintained at or near the site or,  in some cases,
at the regional office or other central location,  because of the
nature of the documents and the burden associated with
maintaining such documents in multiple locations.   These
documents, however, must be incorporated in the record file by
reference (e.g., in the index but not physically in the record
     7 If the site is located at a federal  facility which
requires security clearance, the administrative record file for
that site must be located where security clearance is not
required.  The public must have free access to the record file.

-------
                                   OSWER Directive No. 9833.3A-1

file), and the index roust indicate where the documents are
publicly accessible.  Where a document is listed in the index but
not located at or near the site, the lead agency must, upon
request, include the document in the record file at or near the
site.8  This applies to verified sampling data,  chain of custody
forms, and guidance and policy documents.  It does not apply to
documents in the confidential file.

     Unless requested, the following types of documents do not
have to be located in multiple locations:

Verified Sampling Data9

     Verified sampling data do not have to be located in either
administrative record file.  The sampling data may be left in its
original storage location (e.g., Environmental Services Division
(ESD) or contract laboratory).  Data summary sheets, however,
must be located in the record file.  The index must list the data
summary sheets, reference the underlying verified sampling data,
and indicate where the sampling data can be found.

Chain of Custody Forms10

     As with verified sampling data, chain of custody forms do
not have to be located in either administrative record file.  The
chain of custody forms may be left in the original storage
location.  The index must reference the chain of custody forms
and indicate their location.
     8 40 C.F.R.  §300.805(b).

     9 40 C.F.R. §300.805(a)(1).  "Verified sampling data" are data
that  have  undergone  the  quality  assurance  and  quality  control
process.    "Invalidated  sampling data"  have  been  incorrectly
gathered or  analyzed and  will  not be part  of the  record file.
"Unvalidated sampling data" are  data which has not yet undergone
the quality assurance and quality control process.  Because it is
superseded by verified data, the unvalidated data are not generally
part of th« record files.   However, such data may  in some cases be
relied  on  in selecting a  response action,  such  as  an emergency
removal  where  there  is  no time  for  verification.   Unvalidated
sampling data which are relied on in selecting a  response action
should be included in the record file.

Confidantial and Privileged Documents11

     When a confidential or privileged document is included in
the record file, it should be kept in a confidential portion of
the record file.  The confidential file should be kept in a
locked cabinet at the regional office or other central location.
It should not be located at or near the site.  The index should
identify the title and location of the document, and describe why
the lead agency considers it confidential or privileged.
Furthermore, the lead agency should summarize or redact the
document to make available, to the extent feasible, factual
information (especially if such information is not found
elsewhere in the record file and is not otherwise available to
the public) .  This summary or redaction should be performed as
soon as possible after the determination that a document is
privileged or confidential, and inserted in the portion of the
record file available to the public and included in the index.
See also section III.H. at page 34.

Guidance and Policy Documents

     Guidance and policy documents that are not site specific are
available in a compendium located in the regional office.
("Compendium of CERCLA Response Selection Guidance Documents,"
Office of Waste Programs Enforcement, May 1989.)  This eliminates
the need for reproducing copies of frequently used documents for
each site record file.  The documents in the compendium need not
be physically included in the record file, but the guidance and
policy documents considered or relied on in selecting the
response action must be listed in the record file index along
with their location and availability.  See also section III.I. at
page 37 and Appendix E.

Technical Literature13

     Publicly available technical literature that was not
generated for the site at issue (e.g.,  an engineering textbook),
does not have to be located in the regional office or other
central location or at or near the site.  The document must be
clearly referenced in the index.  However, technical literature
not publicly available must be physically included in the record
file at the regional office or other central location and at or
near the site.  See also section III.J.  at page 38.

F.   Public Availability

F.I. General

     Section 113(k) of CERCLA specifies that the administrative
record "shall be available to the public."  In satisfying this
provision, the lead agency must comply with all relevant public
participation procedures outlined in Sections 113(k) and 117 of
CERCLA.  The NCP (see Appendices L and M) contains additional
requirements on public availability (see also "Community
Relations in Superfund:  A Handbook," October 1988 - OSWER
Directive No. 9230.0-3A; "Community Relations During Enforcement
Activities," November 3, 1988 - OSWER Directive No. 9836.0-1A).

     The availability of the record file will vary depending upon
the nature of the response action.  Different procedures are
outlined below for remedial and removal response actions.

     In all cases,  the lead agency should publish a notice of
availability of the record file when the record file is first
made available for public inspection in the vicinity of the site
at issue.14  The notice should explain the purpose of the record
file, its location and availability, and how the public may
participate in its development.

     The notice should be published in a major local newspaper of
general circulation.  The newspaper notices should be distributed
to persons on the community relations mailing list.  These
notices should also be sent to all known PRPs if they are not
already included on the community relations mailing list.  As
PRPs are discovered, the lead agency should add their names to
the community relations mailing list and mail them all the
notices sent to the other PRPs.  Publication of the notice should
be coordinated with the community relations staff.   A copy of the
notice of availability and list of recipients should be included
in the record file.  Appendix I contains a model notice of
availability.

     This public notice may be combined with other notices for
the same site, such as a notice of availability of the community
relation* information repository, if they occur at the same time.
In addition to the required newspaper notice, the public can be
informed of the availability of the record file through existing
mechanisms (e.g., general and special notice letters, Section
104(e)  information requests, and the community relations mailing
list).   In addition, Headquarters will publish notices in the
     14 See 40 C.F.R. §300.815(a) and §§300.820(a)(1) and (b)

                                12

Federal Register.  They "will be published quarterly and will list
sites where remedial activity is planned.

F.2. Remedial Actions

     The administrative record file for a remedial action must be
available for public inspection when the remedial investigation
begins.15  For example, when the remedial investigation/
feasibility study  (RI/FS) work plan is approved, the lead agency
must place documents relevant to the selection of the remedy
generated up to that point in the record file.  Documents
generally available at that time include the preliminary
assessment (PA), the site investigation (SI), the RI work plan,
inspection reports, sampling data, and the community relations
plan.  The lead agency must continue to add documents to the
record file periodically after they are generated or received
during the RI/FS process.

     The record file must be publicly available both at a
regional office or other central location and at or near the site
(see section II.E. at page 8).16  In addition, the notice of  -
availability should be sent to persons on the community relations
mailing list,  including all known PRPs.

     With the completion of the RI/FS, the lead agency should
undertake the following public participation procedures:

o    Prepare a proposed plan which briefly analyzes the remedial
     alternatives evaluated in the detailed analysis of the RI/FS
     and proposes a preferred remedial action alternative;

o    Make the RI/FS report and proposed plan available in the
     record files both at a regional office or other central
   *  location and at or near the site;

o    Publish in a major local newspaper of general circulation a
     notice of availability and brief analysis of the RI/FS
     report and proposed plan.  The notice should include the
     dates for submission of public comments;

o    Mail th« notice or copy of the notice to all PRPs on the
     coiMunity relations mailing list;

o    Provide a formal comment period of not less than 30 calendar
     days for submission of comments on the proposed plan.  Upon

     timely request the lead agency will extend the public
     comment period by a minimum of 30 additional days.17  [Note:
     The lead agency is encouraged to consider and respond to
     significant comments that were submitted before the public
     comment period.  Considering early comments provides
     practical benefits both substantively and procedurally.
     Early comments may provide important information for the
     selection decision, and early consideration provides the
     public (and, particularly, PRPs) with additional informal
     opportunities for participating in the decisionmaking
     process.];

o    Provide the opportunity for a public meeting(s) in the
     affected area during the public comment period on the RI/FS
     and proposed plan;

o    Keep a transcript of the public meeting(s) on the RI/FS and
     proposed plan held during the comment period and include a
     copy of the transcript in the record file;

o    Prepare a discussion (to accompany or be part of the
     decision document) of any significant changes to the
     proposed plan which occurred after the proposed plan was
     made available for public comment which are reflected  in the
     ROD;

o    Prepare a response to each of the significant comments
     submitted during the public comment period to accompany the
     ROD (see section III.D. at page 30); and

o    Publish in a major local newspaper of general circulation a
     notice of the availability of the ROD and make the ROD
     available to the public before beginning any remedial
     action, as required under Section 117(b) of CERCLA.

     Comments received after signing the ROD should be placed in
a post-decision document file and may be added to the record file
in certain situations  (see section III.N. at page 40).

F.3. Removal Actions

     Section 113(k)(2)(A) of CERCLA requires that the EPA
establish procedures for the appropriate participation of
interested persons in the development of the administrative
record for the selection of a removal action.  "Appropriate"
participation depends on the nature of the removal, as outlined
below.
     17 40 C.F.R. |300.430(f)(3)(i)(C).

                                   OSWER Directive No. 9833.3A-1
Time-critical Removal Actions
     A time-critical removal action is a removal action for
which, based on the site evaluation, the lead agency determines
that a period of less than six months exists before on-site
removal activities must be initiated.  This category includes
emergency removal actions which are described in greater detail
below.

     The administrative record file for these actions must be
available for public inspection no later than 60 days after the
initiation of on-site removal activity.  Where possible, the
record file should be made available earlier.  The record file
must be available both at the regional office or other central
location and at or near the site at issue.

     If, however, on-site cleanup activity is initiated within
hours of the verification of a release or threat of a release and
on-site cleanup activities cease within 30 days (emergency
actions), the record file need only be available at the regional
office or other central location, unless it is requested that a
copy of the record file be placed at or near the site.18

     For all time-critical removals, a notice of the availability
of the record file must be published in a major local newspaper
and a copy of the notice included in the record file.  This
notice should be published no later than 60 days after initiation
of on-site removal activity.

     A public comment period of not less than 30 days should be
held in appropriate situations.   In general, a public comment
period will be considered appropriate if cleanup activity has not
been completed at the time the record file is made available to
the public and if public comments might have an impact on future
action at the site.   If a public comment period is considered
appropriate, it should begin at the time the record file is made
available for public inspection.  Note, however, that even if an
action is completed before the record file is available, the
record fil« should be made available to the public.  The notice
for the public comment period may be combined with the notice of
availability of the record file if they occur at the same time.
The notic* should be mailed to all PRPs on the community

relations mailing list.  The notice should also be sent to all
known PRPs if they are not already on the community relations
mailing list.

     The lead agency must respond to all significant comments
received during the public comment period and place the comments
and the responses to them in the record file (see section III.D.
at page 30).   Whether or not the lead agency holds a public
comment period, comments received by the lead agency before the
decision document is signed and related to the selection of the
removal action must be placed in the record file.  For
information, including comments, generated or received after the
decision document is signed, see section III.N. at page 40.

Non-Time-Critical Removal Actions

     A non-time-critical removal action is a removal action for
which, based on the site evaluation, the lead agency determines
that a planning period of at least six months exists before on-
site removal activities must be initiated.

     The administrative record file for a non-time-critical  .,
removal action must be made available for public inspection when
the engineering evaluation/cost analysis (EE/CA) is made
available for public comment.   The record file must be
available at the regional office or other central location and at
or near the site.  A notice of the availability of the record
file must be published in a major local newspaper and a copy of
the notice included in the record file.  The notice should be
published in a major local newspaper of general circulation.  In
addition, Headquarters will publish these notices in the Federal
Register.  They will be published quarterly and will list sites
where non-time critical removal activity is planned.  The
newspaper notice should be distributed to persons on the
community relations mailing list and placed in the record file.
These notices should also be sent to all known PRPs if they are
not already on the community relations mailing list.  As PRPs are
discovered, the lead agency should add their names to the
community relations mailing list and mail them all the notices
sent to the other PRPs.  Publication of the notice should be
coordinated with the community relations staff.  A copy of the
notice of availability should be included in the record file.

-------
                                   OSWER Directive No. 9833.3A-1

     A public comment period on the EE/CA of not less than 30
days must be held so that interested persons may submit comments
on the response selection for the record file.  Upon timely
notice, the lead agency will extend the public comment period by
a minimum of 15 days.2  A notice of the public comment period
may be combined with the notice of availability of the record
file if they occur at the same time.  The lead agency must
respond to all significant comments received during the public
comment period and place the comments and the responses to them
in the record file (see section III.D. at page 30) ,24

     The lead agency is encouraged to consider and respond to
significant comments that were submitted before the public
comment period.  Considering early comments provides practical
benefits both substantively and procedurally.  Early comments may
provide important information for the selection decision, and
early consideration provides the public (and, particularly, PRPs)
with additional informal opportunities for participating in the
decision making process.

     Comments generated or received after the decision document
is signed should be kept in a post-decision document file.  They
may be added to the record file in certain situations (see
section IPI.N. at page 40).

G.   Maintaining the Record                               ,

     Document room procedures should be established to ensure
orderly public access to the record files.  In establishing
public access procedures, the security and integrity of the
record files must be maintained at all times.

     Each regional office or other central location should have a
reading area where visitors are able to review the record files.
The record file must be available during reasonable hours (e.g.,
9-4, Monday-Friday).  The public reading area should include,
wherever feasible:

o    Administrative record files;

o    Guidance Compendium (see section III.I. at page 37);

o    Acc«»a to a copier; and

o    Sign-in book.

-------
                                   OSWER Directive No, 9833.3A-1


     Controlled access to the files is accomplished by use of a
visitor sign-in book.  Sign-in books help minimize instances in
which documents are lost or damaged.  They also provide
documentation of the lead agency's efforts to provide public
access to the record files.  Pertinent information recorded in
the book should include:

o    Date of visit;

o    Name;

o    Affiliation;

o    Address;

o    Phone number;

o    Site documents viewed; and

o    Cost of copied materials (if applicable).

     The lead agency may choose not to use sign-in books if the
books deter the public from reviewing the record files.

     Since documents in the record file should be complete,
properly organized and legible, the integrity of the record file
must be maintained.  If possible, storage and reading areas
should be supervised to maintain proper security.  Documents
should not leave the document room or be left unattended.  To the
extent feasible, the Administrative Record Coordinator should
check the order of the documents after being viewed by the public
to be certain all documents have been returned intact.  The
documents in the record file should be kept secure, either in a
locked room or in locked cabinets.

     The record file located at or near the site should be
handled with similar care.  If possible, the record file should
be treated as a non-circulating reference; it should not leave
the local repository except under supervision.  The phone number
of a record file contact should be provided to record file users
and to the manager of the local repository so that problems can
be identified and resolved.  This information can be included in
an informational fact sheet accompanying the record file (see
Appendix H).  In addition, the Record Coordinator should plan
periodic reviews of the local record files.

     Where the site is a fund-lead or PRP-lead,  EPA should retain
(in addition to the publicly available record file) a master copy
of the record file at the regional office or other central

                                18

-------
                                    OSWER Directive No..  9833.3A-1

 location,  if feasible.   Where  a  state  or other federal  agency is
 the lead agency at a site,  EPA should  assure that the state or
 other federal agency maintains (in  addition to the publicly
 available record file)  a master  copy of the record file.   The
 record files are permanent  records  that must be retained.

      As to the local repository,  the statute and regulations are
 silent concerning the duration of public availability of  the
 record file.  The lead agency's  primary concern is public
 participation in development of  the administrative record.
 Following initiation of the response action,  public interest in
 background information other than the  Record of Decision  or RI/FS
 may wane.   In any event,  the statutory provisions for judicial
 review and deadlines for filing  cost recovery actions provide
 useful references for keeping  the record file publicly  available.
 See Sections 113(g)  and (h) of CERCLA.

      Where there is ongoing (or  possible)  litigation,  the record
 file in the regional or other  central  location should be
 available  at least until the litigation is over.

      The record file continues to serve as a historical record of
 the response selection,  even after  the statute of limitations for
 cost recovery action has passed.  Where there is considerable
 public interest, the local  repository  may wish to keep  the record
 file-available for public viewing.  ---             -

 H.    Confidential File

      In certain situations, documents  in the record file  may be
 subject to an applicable privilege  (see section III.H.  at  page
 34).   To the extent feasible,  information relevant to the
 response selection which is contained  in a privileged document
 should be  summarized or redacted  as to make the document
 disclosable and then included  in  the publicly accessible portion
^of  the record file.   The privileged document  should be  included
 in  a confidential portion of the  record file.25

      The Administrative Record Coordinator should maintain  a
 confidential portion of the record  file for privileged  documents.
 These documents should be listed  in the index to the entire
 record file and identified  as  "privileged."  The index  should
 identify the title and location of  the privileged document,  and
 describe the basis for the  asserted privilege.

      The confidential portion  of  the record file should be  stored
 in  locked  files at the regional office or other central location
     25  See 40 C.F.R.  §300.810(d).
                                19

-------
                                   OSWER Directive No. 9833.3A-1

and should not be located at or near the site.  The confidential
portion of the record file should be separate from the publicly
available record file to protect against inadvertent disclosure.
Each privileged document should be stamped "confidential" at the
bottom of each page of the document.  Where the material is not a
written document (such as a computer disk or cassette tape) the
jacket should be stamped "confidential."  A complete list of all
materials contained in the confidential portion of the record
file should be maintained by the Record Coordinator.  The Record
Coordinator should also maintain a log which will, include the
time, date, document name, and will identify persons checking out
and returning materials to the confidential file.

     As soon as a new record file is established, a routine
access list for the confidential, file should be prepared for each
record file.  When EPA is the lead agency, this routine access
list must be approved by the Waste Management Division Director
or the Environmental Services Division Director, and ORC.  Once
approval is given, persons on the list will be able to access the
confidential files through the Record Coordinator.  No one should
have access to the confidential files other than those identified
on the routine access list.  For state or other federal agency-
lead sites, the Regions should take steps to insure that state or
other federal agencies develop routine confidential file access
list procedures.

     This policy and procedure for privileged materials does not
supersede any policy and procedures established under the Freedom
of Information Act (FOIA), 5 U.S.C. §552, and EPA regulations
implementing FOIA at 40 C.F.R. Part 2. Upon receipt of requests
for the administrative record file pursuant to FOIA, if the
requester is in close proximity to the record file, the lead
agency may respond to FOIA requests by telling a requester the
location and availability of the record file.  Decisions
regarding disclosures of materials under FOIA should be
coordinated among the various lead agency officials with access
to such materials.

I.   Copying

     Section 117(d) of CERCLA requires that each document
developed, received,  published, or made available to the public
under Section 117 be made available for public inspection and
copying at or near the site.  Under Section 113(k)(2)(B)  of
CERCLA, these documents must also be included in the
administrative record file.  Under these provisions of CERCLA,
the lead agency must ensure that documents in the record file are
available for copying, but does not bear responsibility for
copying the documents themselves.   Therefore, it is preferable


                               20

-------
                                   OSWER  Directive No.. 9833.3A-1

that the record file should be located  in a  facility which
contains a copying machine (e.g., a public library).

     When the administrative record file  is  available  at a
facility at or near the site and copying  facilities are available
there, the lead agency may encourage the  requester to  make use of
the copying facilities at that location.  If copying of the
record file located at or near the site is difficult for a
requesting party, the lead agency may arrange for copying on
behalf of a requester at the regional or  other central location.
The lead agency may ask that requesters arrange for copying by
contractors or commercial copy centers who then bill the
requester directly.

     The lead agency should follow the FOIA  regulations at 40
C.F.R. Part 2, in determining the appropriate charge for copying.
Copying fees should be waived for other federal agencies, EPA
contractors or grantees, and members of Congress.  The EPA
currently charges $.20 a page for paper copies as provided in 40
C.F.R. Part 2.  Reproduction of photographs, microfilms or
magnetic tapes, and computer printouts should be charged at the.
actual cost to the lead agency.

J.   Micrographics

     The lead agency may make the administrative record file
available to the public in microform.26  Use  of micrographics can
significantly reduce the space required to store administrative
record files.   In addition,  micrographics can simplify the tasks
of reproducing copies of the record file and transmission of the
record files to the local repositories.   Any use of micrographics
should be conducted in an orderly manner consistent with records
management procedures.  If using micrographics to maintain the
record files,  the lead agency must provide a micrographic reader
at the regional office or other central location to ensure public
access to the record file.  If a record file is located at or
near the site and micrographics are used,  the lead agency must
ensure that a micrographic reader at that location is available.

     Microform copies of original documents are admissable in
court if created in an organized fashion.   The Business Records
as Evidence Act (28 U.S.C. §1732) specifies that copies of
records, which are made "in the regular course of business" and
copied by any process which accurately reproduces the original,
are "as admissible in evidence as the original itself."  See also
Federal Rules of Evidence 1003.  Since the NCP provides for use
of microform,  microform copies of administrative record documents
     26 See 40 C.F.R. §300.805(c).

                               21

that are produced in the regular course of business are likely to
be admissible in court.

     The Office of Information Resources Management (OIRM)  has
granted approval for the use of micrographics in establishing
administrative records  (see Appendix J).  Any use of
micrographics should still comply with the remaining provisions
of Chapter 6 of the EPA Records Management Manual (7/13/84).

K.   Certification

     A certification as to the completeness of the administrative
record must be performed when the record is filed in court.
Appendix K contains a model court certification.

     When EPA is the lead agency such certification should be
signed by the Regional Administrator's designee, after
consultation with ORC.  Any certification of the record should be
made by program staff and not legal staff.  The region may also
choose to have the Administrative Record Coordinator certify that
the record was compiled and maintained in accordance with
applicable agency regulations and guidance.  Such certification
would attest that the record was compiled in accordance with
current agency procedures and would not address the completeness
of the record file.

     If a state or other federal agency is the lead agency that
agency must certify that the record was compiled and maintained
in accordance with applicable EPA regulations and guidance.
After the state or federal agency provides this certification,
the Regional Administrator's designee should certify as to the
completeness of the record, as provided in Appendix K.

III. CONTENTS OF THE ADMINISTRATIVE RECORD

A.   Remedial Actions

     The administrative record for selection of a remedial action
should consist of:

o    documents which were considered or relied on to select the
     remedial action; and

o    documents which demonstrate the public's opportunity to
     participate in and comment on the selection of the remedial
     action.
     27  See 40 C.F.R. §§300.810 and 300.815.

     Below is a list of documents that are usually generated when
a remedial response .action is selected.  These documents should
be included in the administrative record file if they are
generated and considered or relied on in selecting the remedial
response action.  Documents that demonstrate the public's
opportunity to participate in and comment on selecting the
remedial response action should also be included in the record
file.  Documents not listed below, but meeting the above
criteria, should be included.

Factual Information/Data

o    Preliminary Assessment (PA) report;

o    Site Investigation (SI) report;

o    Remedial Investigation/Feasibility Study (RI/FS) work plan;

o    Amendments to the final work plan;

o    Sampling and Analysis Plan (SAP):  consisting of a quality
     assurance project plan (QAPP) and a field sampling plan;

o    Sampling data:  verified data during the RI/FS, or any data
     collected for previous actions such as RCRA or removal
     actions which are considered or relied on in selecting the
     remedial action.  Unvalidated data should be included only
     if relied on in the absence of validated data (see note 9 at
     page 10);

o    Chain of custody forms;

o    Inspection reports;

o    Data summary sheets;

     to PRPs at an early stage of the RI/FS (see "Interim
     Guidance on Notice Letters, Negotiations, and Information
     Exchange," October 19, 1987 - OSWER Directive No. 9834.1);

o    RI/FS (as available for public comment and as final, if
     different); and

     PRPs) ;28

o    Documentation of informal public meetings:   information
     generated or received during meetings with the public and
     28  Individual  names and addresses of members  of  the general
public  which  are on the community relations mailing  list should
not be  included in the public  record file.   Disclosure  of such
information may result in a Privacy Act violation  (see also section
III.H.  at page  34)  or inhibit  the general  public from requesting
information about  the site.  The lead agency should  then place
individual names and addresses in the confidential portion of the
record  file.

     The administrative record serves as an overview of the
history of the site and should be understandable to the reader.
Appendix B provides a model file structure for organizing the
record file.  Appendix C contains a model index.

B.   Removal Actions

     The administrative record for selection of a removal action
should consist of:

o    documents which were considered or relied on to select the
     removal action; and

o    documents which demonstrate the public's opportunity to
     participate in and comment on the selection of the removal
     action, when appropriate.

     Below is a list of documents that are usually generated when
a removal response action is selected.  These documents should be
included in the administrative record file if they are generated
and considered or relied on when selecting the removal action.
Documents that demonstrate the public's opportunity to
participate in and comment on the removal response action should
also be included in the record file.  Documents not listed below,
but meeting the above criteria, should be included.
     29  See 40 C.F.R. §§300.810 and 300.820.

 history of the site and should be understandable to the reader.
 Appendix B provides a model file structure for organizing the
 record file.  Appendix C contains a model index.

 C.   Imminent and Substantial Endangerment

     Und«r Section 106 of CERCLA, the  EPA may find the existence
 of an ianiiMnt and substantial endangerment to the public health
 or welfare or the environment because  of an actual or threatened
 release of a hazardous substance.

     Determining the existence of an imminent and substantial
 endangerment is an important component in selecting the response
 action.   Therefore,  all documents considered or relied on in
making that determination,  including any risk assessment, and its
 supporting documentation,  must be included in the administrative

                                29

-------
                                   OSWER Directive No. 9833.3A-1

record file.31  If there is proper documentation of the
determination of an imminent and substantial endangerment in the
record file, judicial review of that determination in an action
under Section 106 of CERCLA should be limited to the
administrative record.

D.   Public Comments

     The administrative record file should document the public's
opportunity to be involved in selecting a response action.  This
can be accomplished by including in the record file all documents
related to the opportunity to participate (e.g., notices and fact
sheets), and relevant written comments and information submitted
by the public (e.g., reports and data).

     Public requests for information (e.g., Freedom of
Information Act  (FOIA) requests for copies of reports), need not
be included in the record file.

     The lead agency should request that substantive oral
comments (either in person or over the phone) be put in writing
by the commenter and submitted to the record file.  The commenter
should be advised that the obligation to reduce the comment to
writing rests with the commenter.  The lead agency, however, may
reduce it to writing where the lead agency will want to rely on
the comment.

     The lead agency may respond to comments received prior to a
public comment period in various ways, depending on the nature
and relevance of a particular comment.  The lead agency's
consideration of such a comment may be in the form of a written
response, or reflected by documented actions taken after
receiving the comment, or even by changes in subsequent versions
of documents.  If the lead agency prepares a written response to
a comment,  the comment and response should be included in the
record file.

     The lead agency may notify commenters that comments
submitted prior to a formal public comment period must be
resubmitted or specifically identified during the public comment
period in order to receive formal response by the lead agency.
Alternatively, the lead agency may notify a commenter that the
lead agency will respond to the comment in a responsiveness
summary prepared at a later date.  The lead agency, however, has
     31 See  "Guidance on  Preparing  Superfund  Decision Documents:
The  Proposed  Plan,  The  Record  of  Decision,  Explanation  of
Significant Differences, ROD Amendment,11 OSWER Directive No.
9355.3-02, June 1989.
                                30

-------
                                   OSWER Directive No. 9833.3A-1

no duty to respond to any comments received before the formal
public comment period, or to respond to comments during the
public comment period until the close of the public comment
period.

     The lead agency, however, is encouraged to consider, respond
to and include in the record file significant comments that were
submitted before the public comment period.  Considering early
comments provides practical benefits both substantively and
procedurally.  Early comments may provide important information
for the selection decision, and early consideration provides the
public (and, particularly, PRP's) with additional informal
opportunities for participating in the decision making process.32

     All comments received by the lead agency during the formal
public comment period are to be included in the record file in
their original form, or if not feasible, an explanation should be
placed in the record file explaining why such comments were not
included.  Comments received during the formal public comment
period must be addressed in the responsiveness summary (included
with the ROD In remedial response actions).  The responses may be
combined by subject or other category in the record file.

     Comments which are received after the formal comment period
closes and before the decision document is signed should be
included in the record file but labeled "late comment."  Such
comments should be handled as post-decision information  (see
section III.N. at page 40).

     Comments received after the decision document is signed
should be placed in a post-decision document file.  They may be
added to the record file in limited circumstances (see section
III.N. at page 40).

E.   Enforcement Actions

     The same procedures should be used for establishing an
administrative record whether or not a response action is
selected in the context of an enforcement action.  The following
additional information, however, may assist the lead agency where
there is •nforcement activity.

E.I. Negotiation Documents

     During negotiations with the lead agency, a potentially
responsible party (PRP) may produce documents and claim that they
     32  See 40 C.F.R. §§300.815(b), 300.825(a)(2) and (b)(2).
              /

                                31

-------
                                   OSWER Directive No. 9833;3A-1

constitute confidential business information (CBI) or offers of
settlement subject to Rule 408 of the Federal Rules of Evidence.

     Generally, those documents are not part of the
administrative record for response selection unless they are
submitted by PRPs for consideration in selecting a response
action and are considered or relied on in selecting the response
action.  A privileged document which was considered or relied on
in selecting the response action should be placed in the
confidential portion of the record file.  Such a document should
be summarized and the summary included in the publicly accessible
portion of the record file (see section II.H. at page 19).  If
the information cannot be summarized in a disclosable manner, the
information should be placed in the confidential portion of the
record file only and listed in the index to the file.

E.2. PRP-Lead RI/FS

     Where a PRP is conducting the RI/FS, the PRP must submit all
technical information on selection of the remedial action
generated during the RI/FS to the lead agency.  Technical
information includes work plans, sampling data, reports, and ^
memoranda.  The lead agency, and not the PRP, will establish and
maintain the administrative record file (see "Interim Guidance on
Potentially Responsible Party Participation in Remedial
Investigations and Feasibility Studies," May 16, 1988, OSWER
Directive No. 9835.la and "Model Administrative Order on Consent
for Remedial Investigation and Feasibility Study," January 30,
1990, OSWER Directive No. 9835.10.)

     PRPs may be delegated responsibility for some record file
maintenance activities, such as housing the files at or near the
site.  PRPs cannot, however, be responsible for decisions on what
documents comprise the record file, because of, among other
things, the potential for a conflict of interest.

E.3. Administrative Orders and Consent Decrees

     Final administrative orders and consent decrees issued prior
to selection of the response action (e.g., ordering a PRP to
conduct the RI/FS), should be included in the administrative
record file.  Administrative orders or consent decrees issued
after the signing of the ROD or the action memorandum should not
be included in the record file, unless the consent decree or
administrative order meets the criteria for the inclusion of
post-decision documents in the record file (see section III.N.  at
page 40) .  Drafts of administrative orders and consent decrees
should not be included in the record file, unless the drafts
contain factual information that was considered or relied on and
is not found elsewhere in the record file.

                                32

-------
                                   OSWER Directive No. 9833.3A-1

     The issues relating to administrative records for
administrative orders and de minimis settlements are not
addressed by this guidance.

F.   Excluded Documents

     Certain documents should not be included in the
administrative record file because they are irrelevant to the
selection of the response action.  Documents should be excluded
from the record file if they were not considered or relied on in
selecting the response action.

     Material beyond the scope of the record file should be kept
in separate files maintained at the regional office or other
central location.  These files need not be made publicly
available, although many of the documents in the files may be
available to the public if requested under FOIA.

     Examples of documents that are irrelevant to the decision on
selecting a response action may include Hazard Ranking System
(MRS) scoring packages, contractor work assignments, cost
documentation (as opposed to cost effectiveness information), and
National Priorities List (NPL) deletion information.  If,
howeverj"these documents contain information that is considered
or relied on in the response action selection and is not
contained elsewhere in the record file, then the documents should
be included in the record file.

     Information regarding PRP liability is generally not
included in the record file for selection of the response action
except to the extent such information (typically substance
specific) is considered or relied on in selecting the response
action.  Documents relating to PRP liability, however, should be
compiled and maintained in the regional office or other central
location so that they are available at the time of notice to PRPs
or referral of any litigation.

G.   Draft Documents and Internal Memoranda

     In general, only final documents should be included in the
administrative record file.  The record file should not include
preliminary documents such as drafts and internal memoranda.
Such docuaants are excluded from the record file because drafts
and internal memoranda are often revised or superseded by
subsequent drafts and memoranda prior to the selection of the
response action.  The preliminary documents are, therefore, not
considered or relied on in making the response action decision.

     Drafts (or portions of them) and internal memoranda should
be included, however, in three instances.  First, if a draft

                                33

-------
                                   OSWER Directive No,  9833.3A-1

document or internal memorandum is the basis for a response
decision the draft document or internal memorandum should be
placed in the record file.  This may occur if the draft contains
factual information which was relied on but is not included in a
final document, a final document does not exist, or a final
document did not exist when the response decision was made.

     Second, if a draft document or internal memorandum is
circulated by the lead agency to other persons (e.g., the support
agency, PRPs or the general public) who then submit comments
which the decisionmaker considers or relies on when making a
response action decision, relevant portions of the draft document
or the memorandum and comments on that document should be
included in the record file.

     Third, if a draft document or internal memorandum explains
or conveys decisions on the procedures for selecting the remedy
or the substantive aspects of a proposed or selected remedy
(e.g., the scope of a site investigation or the identification of
potential ARARs), the document should be placed in the record
file, even though the document was signed by a person other than
the Regional Administrator and generated long before the decision
document was signed.

     Examples of internal memoranda and staff notes which should
not be included in the record file are documents that express
tentative opinions or internal documents that evaluate
alternative viewpoints.  Recommendations of staff to other staff
or management should also not be included in the record file,
except for those staff recommendations which ultimately embody a
final decision relevant to response selection.  Drafts and
internal memoranda may also be subject to claims of privilege
(see section III.H., below).

H.   Privileged Documents

     Some documents in the administrative record file may be
protected JLrom public disclosure on the basis of an applicable
privilege.   Any documents which are considered or relied on in
a response action selection, but withheld from the public portion
of the record file based on privilege, must be placed in a
confidential portion of the record file (see section II.H. at
page 19).

     If a document is excluded from the public portion of the
record file based on privilege, the relevant information should,
to the extent feasible, be extracted and included in the public
     33  See 40 C.F.R. §300.810(c).
                                34

-------
                                   OSWER Directive No.. 9833.3A-1

record file.  This can often be accomplished by deleting or
redacting the privileged information from the document.

     The privileges discussed below may be asserted with respect
to documents that are considered or relied on in the selection of
a response action.  The head of the office responsible for
developing the document in question should assert the privilege.
In all cases, the official asserting a privilege should consult
with ORC.

     Public disclosure of a privileged document may result in
waiver of the privilege, although the nature and extent of the
waiver will depend on the privilege asserted and the
circumstances of the disclosure.  If the privilege is waived and
the document becomes a public document, it must be disclosed to
any requester.  In light of the potential for waiver, it is
important that personnel not release potentially privileged
documents to any party without consulting with ORC.

Deliberative Process

     The deliberative process privilege applies to pre-
decisional, deliberative communications that express opinions,
advice, and recommendations of staff to other staff or
management.  The privilege functions to encourage the honest and
free expression of opinion, suggestions and ideas among those
formulating policy for government agencies (see "Guidance for
Assertion of Deliberative Process Privilege," 10/3/84).

     In general, if a document contains factual information
forming the basis for the selection of the response action, the
factual portion should be included in the record file.

     Use of the deliberative process privilege should be balanced
with the statutory mandate of including the public in the
response action selection process.  The privilege should be
asserted if disclosure of the document will have an inhibiting
effect on frank and open discussion among government staff and
decisionmakers.  Documents should not be withheld solely because
they would reveal flaws in the case or information embarrassing
to the government.  Specific procedures exist for assertion of
the deliberative process privilege, which include consulting with
ORC.

Confidential Business Information (CBI)

     The EPA must withhold from the public record trade secrets
and commercial and financial information that is subject to
protection under 40 C.F.R. Part 2.  However, Section 104(e)(7) of
CERCLA greatly restricts the assertions of confidentiality claims

                                35

-------
                                   OSWER Directive No. 9833.3A-1

by PRPs at CERCLA sites.  The decisionmaker should attempt to
avoid using CBI in making response action decisions and can do so
in most cases by using other information instead.   Where the
decisionmaker must use CBI in making its decision, 40 C.F.R. Part
2 and Section 104(e)(7) of CERCLA will apply and such information
should be placed in  the confidential portion of the
administrative record file.

Attorney Work Product

     This'exclusion  applies to documents prepared in anticipation
of possible litigation.  The work product privilege covers all
documents prepared by an attorney or under an attorney's
supervision, including reports prepared by a consultant or
program employee.  Litigation need not have commenced but it must
be reasonably contemplated.  These documents generally relate to
enforcement or defensibility of a decision and are not considered
or relied on in selecting a response action.  These documents
should not, therefore, be in the administrative record file.

Attorney-Client Communication

     The attorney-client privilege applies to confidential
communications made  in connection with securing or rendering
legal advice.  The privilege is limited to communications where
there was an intention to keep the information confidential.

Personal Privacy

     This exemption  covers information about individuals in
personnel, medical,  and similar files, the disclosure of which
would constitute a clearly unwarranted invasion of personal
privacy.  The records must pertain to an individual,  and not a
business, to be excluded from the public portion of the
administrative record file under this exemption.  Often,
information subject  to the protection under the personal privacy
privilege can be redacted from the document and the redacted
version can be placed in the public portion of the record file.

State Secrets

     The lead agency is authorized to exclude from public
scrutiny information which, if released, would harm national
security or interfere with the government's ability to conduct
foreign relations.   This privilege could be particularly
important where the  PRP is a federal agency or a contractor for a
federal agency.  In  the case of a federal facility cleanup,  an
     34  See 40 C.F.R. §300.810(d).

                                36

-------
                                   OSWER Directive No. 9833.3A-1

Inter-Agency Agreement should spell out procedures for asserting
this privilege.

Confidential Informant

     Statements obtained from witnesses who have been granted
confidentiality may be privileged.

Information Exempted by Other Statutes

     Information specifically exempted from disclosure by a
federal statute need not be part of the public record.  The
statute in question must leave no discretion as to the
requirement that matters be withheld from the public, or it must
establish particular criteria for withholding or refer to
particular types of matters to be withheld.

I.   Guidance Documents

     Guidance documents, or portions of guidance documents, that
are considered or relied on in selecting a response action should
be included in the administrative record file for that response-
action.  Any guidance documents generated to address issues that
specifically arise at the site for which the record file is being
compiled should be physically included in the record file.
Certain guidance documents, however, do not have to be kept in
the record file.  Guidance documents not generated for the
particular site for which the record is being compiled may be
kept in a compendium of guidance documents maintained at the
regional office or other central location.

     Each Region should maintain a compendium of guidance
documents which are frequently used in selecting response
actions.  As with an administrative record file, the compendium
of guidance documents must be available to the public, but only
at the regional office or other central location.  The record
file located at or near the site should contain an index to the
compendium of guidance documents.  The Administrative Record
Coordinator should maintain and update the compendium of guidance
documents*  If a guidance document maintained in the compendium
is considered or relied on when making a response action
decision, the index to the record file must list the document and
indicate its location and availability.  See also Appendix E.

     If a guidance document is listed in a bibliography to a
document included in the record file (e.g., listed in the
bibliography to the RI/FS), it need not be listed again in the
     35  See 40 C.F.R. §300. 805 (a) (2)
                                37

-------
                                   OSWER Directive No. .9833.3A-1

index to the record file.  In this case, however, the index must
state that documents listed as bibliographic sources might not be
listed separately in the index.

     If a guidance document which is not included in the guidance
compendium is considered or relied on in selecting the response
action, the document should be physically included in the record
file.

J.   Technical Literature

     Technical literature generated for the site at issue should
be physically included in the administrative record file for that
site, whether or not it is publicly available.

     Similarly, technical literature not specifically generated
for the site which is not publicly available should also be
included in the site-specific record file.  Such documents
include technical journals and unpublished documents that are not
available through the Library of Congress or not circulated to
technical libraries.

     Publicly available technical literature not generated for
the site, however, need not be located at or near the site or at
the regional office or other central location if the documents
are referenced in the index to the record file.   These
documents do not have to be physically included in the record
file, unless requested, because they are already available to the
public.  Copying such documents creates a significant burden to
the lead agency and copyright laws may pose additional barriers
to such copying.  Examples of publicly available technical
literature include engineering manuals, groundwater monitoring or
hydrogeology textbooks, ATSDR toxicological profiles, and
articles from technical journals.

     If technical literature is listed in a bibliography to a
document included in the record file (e.g., listed in the
bibliography to the RI/FS), it need not be listed again in the
index to the record file.  In this case, however, the index must
state that documents listed as bibliographic sources might not be
listed separately in the index.

     Computer models and technical databases need not be
physically included in the record file but should be referenced
in the index to the record file and made available upon request.
Printouts or other documents produced from the models and
databases should be physically included in the record file if
     36  See 40 C.F.R. §300.805(b) (3) .

                                38

-------
                                   OSWER Directive No. 9833.3A-1

such documents contain information which was considered or relied
on in selecting the response action.

K.   Legal Sources

     Copies of statutes and regulations cited in documents
included in the record file need not be included in the record
file if they are readily available to the public.  For example,
the NCP and other regulations are easily accessible since they
are published in the Federal Register and the Code of Federal
Regulations (C.F.R.).

     Copies of the actual standards (statutes or regulations)
comprising federal and state ARARs should be physically included
in the record file if they are not easily accessible.  Also,
other federal and state criteria, advisories, and guidance
documents pertinent to the site  (e.g., what the EPA refers to as
"TBCs," or standards "to be considered"), may not be easily
accessible.  If such documents are cited in an RI/FS, appendix to
the RI/FS, EE/CA, or ROD, those advisories which are not readily
available should be included in the record file.

L.   NPL Rulemaking Docket Information

     Generally, information included in the National Priorities
List (NPL) rulemaking docket, such as the Hazard Ranking System
(HRS)  scoring package and comments received on the listing, need
not be included in the record file for selection of a response
action.  The NPL docket contains information relevant to the
decision to list a site, which may be irrelevant to the decision
on response action selection.

     Documents in the NPL docket which contain sampling data or
other factual information which was considered or relied on in
selecting a response action should be included in the record file
if the information is not available already in the record file.
Such information may include early sampling data taken by parties
other than the lead agency or its contractors (e.g., a State).

M.   RCRA Documents

     If «i action is taken under CERCLA at a site with a history
of Resource Conservation and Recovery Act (RCRA) activity, much
of the information relating to those RCRA activities may be
considered or relied on in making the CERCLA response action
selection.  Any relevant RCRA information, particularly
information on waste management and RCRA corrective action at the
site,  should be included in the administrative record file (e.g.,
RCRA permit applications, inspection reports, RCRA Facility
Assessment (RFA), RCRA. Facility Investigation (RFI), Corrective

                                39

-------
                                   OSWER Directive No. 9833.3A-1

Measures Studies  (CMS), or responses to RCRA information
requests).

     Not all pre-existing RCRA information will be considered or
relied on in selecting a CERCLA response action, but information
on types of wastes, quantity of wastes, and observations of
potential threats gathered during RCRA investigations generally
will be considered and thus should be included in the record
file.

N.   Post-Decision Information

     In all cases, documents generated or received after signing
the decision document should be kept in a post-decision document
file.  This file  is not part of the administrative record file
and should be maintained only at the regional office or other
central location.

     In general, post-decision documents should not be added to
the administrative record file.  Since the record file contains
the information which was considered or relied on in selecting
the response action, documents generated or received after
selecting the response action are not relevant to that response
decision and should not be included in the record file.  Such
documents may, however, be relevant to later response selection
decisions and, if so, should be included in the record file
pursuant to Section 300.825 of the NCP.

     Documents kept in the post-decision document file may be
added to the record file in the situations described below:

o    Where a decision document does not address or reserves a
     portion of the decision to be made at a later date.37  For
     example, a decision document that does not resolve the type
     of treatment technology.  In such cases, the lead agency
     should continue to add documents to the record file which
     form the basis for the unaddressed or reserved portion of
     the decision;

o    Wh«r« there  is a significant change in the selected response
     action.   Changes that result  in a significant difference
     to • basic feature of the selected remedial action (e.g.,
     tiaing, ARARs), with respect to scope, performance, or cost
     37 40 C.F.R.  §300.825(a) (1) .

     58 40 C.F.R. §300.825(a) (2) .  See 40 C.F.R. |300.435(c)(2)(i).

-------
                              OSWER Directive No.  9833.3A-1

may be addressed in an explanation of significant
differences. Section 117(c) of CERCLA states:

     [a]fter adoption of a final remedial action plan -
     (1) if any remedial action is taken, (2) if any
     enforcement action under section 106 is taken, or
     (3) if any settlement or consent decree under
     section 106 or section 122 is entered into, and if
     such action, settlement, or decree differs in any
     significant respects from the final plan, the
     President or the State shall publish an
     explanation of the significant differences and the
     reasons such changes were made.

The record file should include the explanation of
significant differences, underlying documentation for the
response action changes, any significant comments from the
public, and the lead agency responses to any significant
comments.  A formal public comment period is not required
for an explanation of significant differences;

Where the changes are so significant that they fundamentally
alter the very nature or basis of the overall response
action.  Such changes will require an amended decision
document. 9  The Region will decide whether a change to a
response action is considered a significant or a fundamental
change for purposes of addressing the change (see Chapter 8
of "Interim Final Guidance on Preparing Superfund Decision
Documents:  The Proposed Plan and Record of Decision," June
1989, OSWER Directive NO. 9355.3-02).

When the decision document is amended, the amended decision
document, the underlying documentation, any significant
comments from the public, and the lead agency's responses to
any significant comments, should be included in the record
file.  ROD amendments will require a formal public comment
period;40

where comments containing significant information are
submitted by interested persons after the close of the
public comment period.  The lead agency must consider such
comments only to the extent that the comments contain
significant information not contained elsewhere in the
record file which could not have been submitted during the
public comment period and which substantially support the
39 40 C.F.R. §300.825(a) (2) .

40 40 C.F.R. §300.435(0) (2) (ii).

     need to significantly alter the response action.41
     Documents meeting this test should be included in the record
     file, along with the lead agency's responses to the
     significant comments, whether or not such information
     results in a change to the selected decision.  In this case,
     the comments and the lead agency responses to such comments,
     including any supporting documents, should be included in
     the record file; and

o    Where the lead agency holds public comment periods after the
     selection of the response action.4   The lead agency may
     hold additional public comment periods or extend the time
     for submission of public comment on any issue concerning
     response selection.  Such comment should be limited to the
     issues for which the lead agency requested additional
     comment.  All comments responsive to the request submitted
     during such comment periods, along with any public notices
     of the comment period, transcripts of public meetings, and
     lead agency responses to the comments, should be placed in
     the record file.

IV.  INVOLVEMENT OF OTHER PARTIES

A.   States

A.I. State Involvement in Federal-Lead Sites

     The administrative record for a federal-lead site must
reflect the state's opportunity to be involved in selecting the
response action.  The record for a remedial action should include
documents that reflect at least the following state participation
or the opportunity for state participation:43

o    Letter to state requesting identification of ARARs and the
     final response from state identifying ARARs (and
     certification from the state);

o    Comments, or the opportunity to comment, on a proposed
     finding or decision to select a response action not
     attaining a level or standard of control at least equivalent
     to a state ARAR;
     41 40 C.F.R. §300.825(c).

     42 40 C.P.R. §300.825(b) .

     43 See also Section 121 (f) of CERCLA

                               42

-------
                                   OSWER Directive No.-  9833.3A-1

 o     Comments, or  the  opportunity to comment, on the  final draft
      RI/FS, the proposed  plan and EPA responses to the  comments;

 o     Significant post-decision comments by the state  and  EPA
      responses to  the  comments  (place in the post-decision
      document file for possible inclusion in the record file -
      see  section III.N. at  page 40).

      The  administrative record for a removal action should
 reflect any state  participation, especially any state comments
 and  EPA responses  to the  comments.

      The  record file should only include final state  comments,
 unless the comments explain or convey decisions on substantive
 aspects of a proposed  or  selected remedy (e.g., the scope of  a
 proposed  action or the identification of potential ARARs).   Any
 preliminary deliberations between the state and EPA relevant  to
 the  response selection need not be part of the record file if
 superseded by documentation of the state's final position.

      The  governing body of  an Indian tribe should be  afforded the
 same  treatment as  a state in accordance with Section  126 of
 CERCLA.

.A.2..  Federal Involvement  in .State-Lead Sites

      Where a state has been officially designated the lead agency
 for  a CERCLA site, the state must compile and maintain  the
 administrative record  for that site in accordance with  Section
 113(k) of CERCLA and Section 300.800 of the NCP.  Since EPA  has
 ultimate  responsibility for both the selection of a response
 action (e.g., EPA  signs the ROD) and the record on which that
 response  action is based, EPA must participate in compiling  and
 maintaining the record.   In such cases, EPA must assure that  the
 record file forms  a complete basis for the selection  of the
 response  action.

      The  state as  lead agency must maintain the record  file  at a
 state office (e.g., the state's central environmental agency
 office) and at or  near the  site.  At a minimum, the state as  lead
 agency also Bust transmit a copy of the index, the RI/FS work
 plan, th« BZ/FS released  for public comment, the proposed plan,
 and  any poblic comments received on the RI/FS and the proposed
 plan to the appropriate EPA Regional office.   These  documents
 should be transmitted  to  EPA as they are generated or received.
 Transmittal of the index  will not suffice.  In addition, other
 documents may be requested  by EPA on a case-by-case basis.
         See 40  C.F.R.  §300.800(C).

                                43

-------
                                   OSWER Directive No. 9833.3A-1


     The Superfund Memorandum of Agreement (SMOA), or Cooperative
Agreement (CA), must address the administrative record
requirements.  The following language should be included in the
SMOA or CA where the state has been officially designated the
lead agency for a CERCLA site:

     The state must compile and maintain the administrative
     record upon which the selection of the [remedial,
     removal] action is based.  The compilation and
     maintenance of the record must follow 40 C.F.R. Part
     300, Subpart I and EPA guidance on the administrative
     record.  The administrative record must be located at
     the state [environmental agency] office,  and at or near
     the site.  In addition, the state must submit copies of
     the index, the RI/FS workplan, the RI/FS released for
     public comment, the proposed plan, and any public
     comments received on the RI/FS and proposed plan to the
     EPA Regional office, as they are added to the
     administrative record file.  In addition, the state
     must submit other documents that are requested by EPA.
     The state shall comply with Section 113 of CERCLA and
     any applicable regulations.  EPA may require the
     retention of other documents for cost recovery
     purposes.

     The record file compiled by the state should reflect EPA's
participation, comments, concurrence, and disagreements at the
same stages as are required for state involvement in a federal-
lead site.   The state must place in the record file any documents
submitted by EPA for inclusion in the record file.

B.'   Federal Facilities

     Federal agencies have the responsibility, pursuant to
Executive Order 12580, to establish the administrative record for
federal facilities under their jurisdiction,  custody, or control
where using CERCLA authority for a response action.  The record
file for a federal facility must include all documents considered
or relied on in selecting a response action,  including documents
submitted by EPA on the selection of the response action.  The
federal agency must comply with all NCP (see Appendix M) and
CERCLA requirements in compiling and maintaining the record,
including the minimum public participation requirements in
Sections 113 and 117 of CERCLA.
     45  See 40 C.F.R. §300.800(b).
                                44

-------
                                    OSWER Directive No. 9833.3A-1

      The federal agency must maintain the record file at or near
 the site and ensure easy public access to the record file.   If,
 for example, a site is a Department of Defense facility, the
 record file should be housed in a location which does not require
 military clearance for access.   The federal agency should keep a
 complete copy of the record file at a location within the federal
 agency office comparable to an EPA Regional office.

      At NPL sites and any other site where EPA is involved in
 selecting a response action at a federal facility, EPA must
 participate in compiling and maintaining the record.  In such
 cases, EPA must assure that the record file forms a complete
 basis for the selection of the response action.   At a minimum,
 the federal agency must transmit a copy of the index, the RI/FS
 workplan, the RI/FS released for public comment,  the proposed
 plan, and any public comments received on the RI/FS and proposed
 plan to the appropriate EPA Regional office.  These documents
 should be transmitted to EPA as they are generated.  Transmittal
 of the index will not suffice.   In addition, other documents may
 be requested by EPA on a case-by-case basis.  Inter-Agency
 Agreements (lAGs)  should spell out procedures for compiling and
 maintaining the record.

 C.    ATSDR

—-    Participation in the selection of a response action by the
 Agency for Toxic Substance and Disease Registry (ATSDR)  should be
 reflected in the administrative record.  The record file must
 include the initial and subsequent health assessments and any
 other information EPA solicits and obtains from ATSDR which EPA
 considers or relies on in its selection of a response action.

      Draft versions of the health assessment and other draft
 documents upon which ATSDR comments should not be included  in the
 record file.   If,  however,  EPA solicits comments from ATSDR on a
 draft document such as a draft work plan or RI report,  and
 receives formal comments from ATSDR which EPA considers or  relies
 on in selecting a response action,  then the document and comments
 should be included in the record file.

      In the event that the ATSDR health assessment and EPA's  risk
 assessment appear inconsistent,  a document explaining the
 difference should be generated and placed in the record file.

 D.    Natural Resources Trustees

      Section 122(j)(l)  of CERCLA requires that the EPA give
 notice to the Natural Resources Trustee of a release or
 threatened release of any hazardous substance which may have
 resulted in damages to natural  resources.   The administrative

                                45

-------
                                   OSWER Directive No.  9833.3A-1

record file must include the notice to the Natural Resources
Trustee, and any subsequent final communications (e.g.,  a release
or final report).  In addition, any factual information provided
by the Natural Resources Trustee which is considered or relied on
in selecting a response action should be included in the record
file.

     In the event that the Natural Resources Trustee's damage
assessment and EPA's risk assessment appear inconsistent, a
document explaining the difference should be generated and placed
in the record file.

                             APPENDIX B

                        MODEL FILE STRUCTURE


    This model file structure may be us«d to compile an
administrative record fil« for * remedial action, a removal action,
or a combination of both remedial and removal actions.  If the
record documents a remedial action decision, section 2 of the file
will contain only those removal action documents which (a) predate
the remedial record of decision and (b) are relevant to the
selection of the remedial action.  If the record documents a removal
action decision, sections 3, 4, and 5 of the file will contain only
those remedial action documents which (a) predate the removal action
memorandum and (b) are relevant to the selection of the removal
action.

    Justification is unnecessary for file categories without any
documents.  Those categories should be left out of the index.

    A document should be filed in only one category, even if it
falls into more than one category.  It may be referenced in another
category.  If necessary, additional eubcategoriee may be developed
to accommodate documents not falling in any of the defined
subcategories.  Avoid adding categories of miscellaneous documents.

    The correspondence subcategory can include comments and
responses specific to the category.  If the comments and responses
are general in nature or address more than one category,  they may be
included in the public participation category.

        This manual describes how to use the ^Compendium of CERCLA Response Selectmen
 Gu;Ja.-.-i Documents' iComcendiumi.  Each US. Environrr.ental Protection Agency  >E?Ai
 Regional Ot'fice maintains a compendium of guidance documents frequently used during
 Je\elopment ind selection of response actions under the Comprehensive Environmental
 Response. Compensation, and Liability Act (CERCLA).

        EPA Headquarters used several sources to develop the initial Compendium.  These sour;»s
 included a pamphlet titled "Selected Technical Guidance for Superfund Project** (OS\v ER
 Directive 9200.7-01); the OSWER Directive System; the Superfund, Resource Conservation and
 Recovery Act (RCRA). and Enforcement dockets; the Hazardous Waste Collection Database; and
 any existing regional compendiums. The documents in the Compendium are referenced in
 administrative records for decisions on selection of response actions.

       The administrative record described here is the body of documents that form the basis for
selection of a CERCLA res poos* actioa. Establishment of the administrative record  is required
by §113(k)  of CERCLA.  An administrative record is the compilation of documents considered or
relied on by EPA in making a decision.  Documents that EPA anticipate* will be included in the
administrative record when the decision on t response action selection is nude, are referred :o is
the 'administrative record file.*  Guidance documents, or portions of guidance documents, that
are considered or relied on in selecting a CERCLA response action should be part of an
administrative record file.

       Certain frequently used guidance documents may be referenced in the index to an
administrative record but not physically included  in the administrative record file. The reference
should indicate the title and location of aay documents included in the administrative record but
maintained in the Compendium, which is kept at a central regional location.  If a guidance
document that • aoc listed ia the. Compendium is considered or relied on in selecting the response
actioa, the  dooHMstt matt be physically included in the administrative record Hie. The
Compendium amfct reduce the burden of copying and storing multiple copies of frequently used
guidanc*
       Section 2.0 of this manual briefly discusses use of the Compendium by EPA personnel and
the public. Section 3.0 discusses the Compendium's file ind index structure.  Documents in the
Compendium are filed ia three-ring binders and listed oa aa index which is generated by and
                                         (1)

 maintained on a computer database. Procedures for updating the Compendium are presented .n
 Section 4 0.

                         2.0   OVERVIEW OF COMPENDIUM USE

        The Compendium is intended for use by two groups: EPA personnel, during :he sn.-jsi
 of response action selection and administrative record development,  and the public, for re vie* ;f
 documents referenced in the index to an administrative record.

       The user should note that although the term 'guidance' is often used in discussing the
 Compendium, it does not imply that only guidance documents are included. The documents may
 also be policies, memoranda, clarifications, cast studies, manuals, handbooks, reports, and other
 documents used in the selection of CERCLA response actions.

 2.1           USE BY EPA PERSONNEL

       EPA penoonel use the Compendium primarily to reference frequently used guidance
documents that may be maintained in the Compendium rather than physically included in each
administrative record file.  The index must indicate which documents are physically located in
the Compendium and must specify the  location and accessibility of the Compendium. The  index
should also reference only the specific documents in the Compendium that  were considered or
relied on for the site for which the record is being compiled. The index should not reference the
entire Compendium.

2.2           USE BY THI PUBLIC

      As with any unrestricted document included ia a record, the  Compendium documents  are
accessible for public review.  Whea EPA publish** a notice of availability of aa administrative
record filt, that node* will include the location of the Compendium. The Compendium will be
available for ptjftfla. vfcwiaf at a ctotral rtfioaal establishment (for •xampU, the EPA Regional
Office), and Mftaf or near tat sitt for which the record is being compiled.  (See Appendix  A for
a list of the) tooHta of each refioaal copy of the Compendium aad the names of the Regional
Administrative; Record Coordinators.)

                        3.0   STRUCTURE OF THE COMPENDIUM

        Currently, the Compendium i$ organized into 10 categories.  An overview Of the t-.;e
 ;:r-v:.:* .5 ^resented below, is well as 3 discussion of the mdet that identifies the doc-.T.ents
 incluJej :.i jhe Compendium.  This section also discusses the data elements identified  ,n t.'-.e
 indev  The Jjta elements provide vital information on the documents included in the
 Compendium and are contained in  a database used to compile the Compendium and genera:e :.-«
 index.

 3.1           FILE STRUCTURE

        The Compendium is structured according to 10 major categories that generally reflect the
 various components of a response action selection under CERCLA. Table 3-1 lists the current
 Compendium categories. The documents are further grouped into subcategories that indicate
 their more specific nature, when applicable. For example, the remedial investigation/feasibility
 study (RI/FS) section of the Compendium is broken down into more specific subcategories to
 identify the wide range of RI/FS documents available. When the documents apply to multiple
 categories, secondary references axe provided in the Compendium index.

       Each document has been assigned a unique four-digit document number. The  bound
 documents contained in each category are arranged numerically.  When a user wants to access a
 document,  he or she will find the document filed according to the assigned number. The four-
 digit number series assigned to each category are also listed in Table 3-1.

 3.2           INDEX STRUCTURE

    -   When aa administntivt record index refers to a document contained in the Compendium.
 that document is also identified In the Compendium index. The  index, contained as the first
document ia the> Coapeadiom, provides the information necessary to identify and locate the
desired docuaMel (For a copy of the current Compendium index, see Appendix B.)
              i to aMet cases the user will know the title of the document rather than the number
assigned, the) index lira the documents under each category ia alphabetical order.  An
alphabetical listing of secondary references follows the primary documents listed under each
category.

 [Address]

 Dear {Name of Contact]:

     The U.S.  Environmental Protection Agency is required by law to
 establish administrative records "at or near a facility at issue."
 This administrative record consists of information upon which the
 Agency bases  its selection of response action for a particular
 Superfund site.

     By providing the public with greater access to these records,  it
 is our hope that they will be better equipped to comment
 constructively on site activities and to understand the issues
 relating to the selection of the response action at the site.

     we appreciate having the [Name of local repository] as the
 designated administrative record facility for the [Name of site]
 Superfund site.   The enclosed record files, along with any future
 documents relating to technical activities at the site should be
 placed in the [Name of local repository] and be available for public
 review.   The  record files should be treated as a non-circulating
 reference - it should not be removed from your facility.

     Also enclosed is a fact sheet to assist you and your staff in
 answering questions posed by the public concerning administrative
 records  for selection of response actions at Superfund sites.
 Please feel free to distribute this guide to the public.

     To ensure the receipt of the administrative record file,  I would
 appreciate your completion of the attached Document Transmittal
 Acknowledgment form.  Please return this form in the enclosed self-
 addressed,  stamped envelope.

                            R«cords in Local
    The  "administrative  record"  is the collection  of  documents which
 fora  the  basis  for  the selection of a response  action at  a  Superfund
 site.  Under  section  113(k)  of the Comprehensive Environmental
 Response, Compensation,  and  Liability Act,  as amended by  the
 Superfund Amendments  and  Reauthorization Act  (CERCLA),  EPA  is
 required  to establish an  administrative record  for every  Superfund
 response  action and to make  a copy of the administrative  record
 available at  or near  the  site.

    The administrative record file must be  reasonably available for
 public review during  normal  business hours.  The record file should
 be treated as a non-circulating  reference document.   This will allow
 the public greater  access to the volumes and also  minimize  the risk
 of loss or damage.  Individuals  may photocopy any  documents
 contained in  the  record  file,  according to  the  photocopying
 procedures at the local  repository.

    The documents in  the  administrative record  file may become
 damaged or lost during use.   If  this occurs, the local  repository
 manager should contact the EPA Regional Office  for replacements.
 Documents may be  added to the record file as the site work  ,_
 progresses.   Periodically, EPA may send supplemental  volumes and
 indexes directly  to the  local repository.   These supplements should
 be placed with the  initial record file.

    The administrative record file will be  maintained at  the local
 repository until  further  notice.   Questions regarding the
maintenance of the  record file should be directed  to  the  EPA
 Regional Office.

    The Agency welcomes comments at any time on documents contained
 in the administrative record file.   Please  send any such  comments to
 [name and address].   The  Agency  may hold formal public  comment
period* at certain  stage* of response process.  The public is urged
to use these  formal review period* to submit their comment*.

    For further information  on the administrative  record  file,
contact [name ejmft phone no.  of Administrative Record  Coordinator].

   EPA agrees that while subpart I
 includes ample information on the
 requirements of the administrative
 record a brief clarification would help
 to differentiate the record from the
 information repository.
   The  information repository includes a
 diverse group of documents that relate
 to a Superfand site and to the Superfund
 program in general including document!
 on site activities, information about tha
 site location, and background program
 and policy guide*. EPA requires an
 information repository at all remedial
 action sites and any sJte where a

   A commenter asked that the phrase
 "but not in all cases" be deleted from
 i 300.«10(a). or specify the cases wne.-e
 documents are excluded from  the
 administrative record. EPA believes it i:
 better not to attempt to list excluded

 documents that will be genersted for a

 these documents should be excluded

 example, that although a health
 assessment dona by ATSDR would
 normally be included in the
 administrative record it would not be if
 the assessment was generated by
 ATSDR after the response is selected.
  Others commented that certain
 documents  should always be included in
 the administrative record EPA believes
 that only a small group of documents
 will always be generated for every type
 of CERQLA site, tinea each lite is
 unique. Other documents may or may
 not be generated or relevant to the

 start a publicly available record of
 information relevant to the response
 seiection.
   One comment suggested that
 interested persons would have no
 chance to comment on the formation of
 the RI/FS work plan. The comment
 suggested that the record file should be
 available before the RI/FS work plan is
 approved, e.g.. with a draft work plan or
 statement of work. EPA disagrees.
 Approved work plans are often
 amended. An interested person may
 comment on the scope or formation of
 the work plan, and such comments can
 be taken into account by the lead
 agency and incorporated into a final or
 amended work plan. Such comments
 must be considered if submitted during
 the comment period on the proposed
 action,

 that it publish a joint notice of

instead of "no later than 60 days a/tar

that It often take* 60 days ta stabilise a

bellrres that tht overriding task of

of necessary stabUixattoa. rather than
administrative duties. C^*1'" and
advertising tht rtcord before a sitt has
