 Promoting better understanding of EPA's oversight role and activities for the WIPP


                            A  Message  From  the  Director
                            H
      ello. My name is Elizabeth Cotsworth and I am
      the new Director of the Office of Radiation and
      Indoor Air (ORIA). Prior to joining ORIA, I was
the Director of EPA's Office of Solid Waste where I man-
aged the Agency's national hazardous and solid waste
programs. I want you to know that one of my highest
priorities is making sure that radioactive waste is safely
stored, disposed, and managed at the WIPP. EPA con-
tinues to ensure the Department of Energy (DOE) com-
plies with our standards and that the WIPP safely
contains transuranic waste. We do this by inspecting the
WIPP facility and DOE's transuranic waste  generator
sites. We are also working very hard preparing for the
WIPP recertification process;  we expect to receive
DOE's first recertification application by March 2004.
  I also want to  take this opportunity to reaffirm
EPA's commitment to keep you informed about our
continuing oversight role and activities for the WIPP.
I feel that it is important that you understand how we
do our job and why we make the decisions we make.
My  staff and I care  about what you think and are
open to responding to your questions and concerns.
Please feel free to contact us either by: sending your
questions and comments by email to:  radiation, ques-
tions@epa.gov; leaving a message on our WIPP In-

questions and comments by U.S. mail to: Betsy Fori-
nash, Director, WIPP Program,  Office of Radiation
and Indoor Air, Mailcode 6608J, 1200 Pennsylvania

    Focus On decertification
What is Recertification?

  It is a process to reaffirm that the WIPP con-
  tinues to meet all the requirements of EPA's
disposal regulations.  The  recertification
process will ensure that the WIPP is operated
using  the most accurate, up-to-date informa-
tion available and provides documentation re-
quiring DOE to operate by to these standards.
Recertification is  not a reconsideration of the
decision to open WIPP. EPA is required by law
to evaluate all changes in conditions or activi-
ties at WIPP every five  years to determine if
WIPP  continues to comply with our disposal
regulations. The  first  of these recertifications
occurs in 2004 and will include a review of all
of the changes made at the WIPP facility since
our initial certification decision in 1998.
   Since our initial certification decision in
1998, we have been conducting independent
technical reviews and  inspections annually
of all  WIPP activities related to compliance
with our disposal regulations. EPA reviews
all changes in activities  or  conditions and
may modify, suspend or revoke certification
at any time to prevent or quickly reverse a
potential danger to public health.  Recertifi-
cation evaluates  changes at the WIPP.
  The 1998 Certification identified the start-
ing (baseline)  conditions for the WIPP site
and established the waste and facility char-
acteristics necessary  to ensure proper dis-
posal  in  accordance  with our  disposal
regulations. At that time,  EPA and DOE un-
derstood that future information and knowl-
edge gained from the  actual  operations  of
the WIPP would  result in changes to the best
practices and procedures for the facility.  In
recognition of this, EPA is required by law to
evaluate all changes  in conditions or activi-
ties at WIPP every five years to determine if
WIPP  continues to comply with our disposal
regulations. The  first of these recertifications
occurs in 2004 and will include a review of
all of the changes made at the WIPP facility
since our initial certification decision in 1998.

DOE  will apply for recer-
tification.
                                              While EPA has been tracking all changes at the WIPP, during recertification,
                                           we will conduct a more in-depth look at the  collective effect of changes DOE
                                           made in WIPP operations over the last five years. As part of this recertification,
                                           DOE is required to produce a new performance assessment in order to evaluate
                                           changes to the facility and the environment and to reaffirm that the WIPP con-
                                           tinues to meet all of EPA's disposal regulations requirements. Additionally, DOE
                                           must submit a "Recertification Application" to  EPA containing the results of the
                                           performance assessment and identifying all changes and updates to the WIPP.
                                           EPA must receive the application no later than March 2004 (five years from when
                                           waste was first received at the WIPP).

                                           EPA will review  DOE's application.
                                              Once EPA determines that the application is complete, we must make a de-
                                           cision on recertification within six months. The focus of our review will be on
                                           areas of change  identified by DOE, in order to ensure that their cumulative ef-
                                           fects have been adequately addressed. Areas that DOE states have not changed
                                           will be reviewed by EPA to verify that they have not. DOE must demonstrate
                                           that it  meets all  aspects of  the Agency's disposal regulations. When we deter-
                                           mine that we have received a complete Recertification Application from DOE,
                                           we have six months from that date to make our recertification decision. We will
                                           notify DOE of our decision in the Federal Register and, if we approve DOE's Re-
                                           certification Application, it will serve as the new "baseline" for the next WIPP
                                           recertification in 2009.

                                           The public is  invited to comment.
                                              EPA welcomes and encourages  public  involvement in the  recertification
                                           process. We are most interested  in public comment on any issues  or changes
                                           where  changes have occurred which that may potentially impact  the WIPP's
                                           ability  to remain in compliance with the requirements in our disposal regula-
                                           tions, as well as any areas where the public believes that changes have occurred
                                           and have not been identified by DOE.

                                           EPA will make information available to  the
                                           public.
                                              EPA will place all DOE submissions in the public docket and will solicit pub-
                                           lic comments on DOE's Recertification Application. EPA will also make sure that
                                           key information, including DOE's application, will be is available on our web-
                                           site at:  www.epa.gov/radiation/wipp/ and in our dockets. And, we  will estab-
                                           lish clear procedures for submitting comments will be outlined as well. We plan
                                           to meet informally with stakeholders  during our review to discuss issues of in-
                                           terest in the application.
                                              After we determine we have received a complete Recertification Application
                                           from DOE and before making our recertification decision, EPA staff will meet in-
                                           formally with key stakeholders to discuss any issues of concern. We will post
                                           our recertification decision on our EPA WIPP website, announce our decision via
                                           email to interested stakeholders, publish our  decision in the  Federal Register,
                                           and write an article summarizing our decision for inclusion in a future next issue
                                           of the  EPA WIPP Bulletin.

Recertification of theWIPP Facility
                This provides an overview ofEPA's recertification process for the WIPP
                                     that will take place in 2004.
What is
Recertification?

  EPA is required by law to evaluate
all changes in conditions or activities
at WIPP every five years to determine
if WIPP continues to  comply  with
EPA's disposal regulations for the fa-
cility. The first of these recertifications
will occur  in 2004 and will include a
review of all of the changes made at
the WIPP  facility  since the original
1998 EPA certification.  It is not  a re-
consideration of the decision to  open
WIPP,  but  a process to reaffirm that
the WIPP meets all  requirements of
the disposal regulations.The recertifi-
cation process will not  be used to ap-
prove any  new significant changes
proposed by DOE; any such propos-
als  will  be addressed  separately by
EPA. Based on our review of annual
change reports, EPA does not antici-
pate any issues that would prevent
recertification in  2004. However, re-
certification ensures that the WIPP is
operated using the most accurate and
up-to-date information available and
provides documentation  requiring
DOE to operate to these standards.

EPA  Reviews Changes
at the WIPP Annually

  Since   the  1998   certification,
EPA has been conducting indepen-
dent technical review and inspections
of  all  WIPP activities  related  to
compliance with EPA's  WIPP disposal
regulations. EPA reviews all changes
in activities  or conditions and  may
modify, suspend or revoke certifica-
tion at any time to prevent or quickly
reverse a potential danger to public
health.
  The 1998 certification identified
the  starting (baseline) conditions for
the  WIPP  site  and  established  the
waste and facility characteristics nec-
essary to  ensure proper disposal in
accordance with  the regulations.  At
that time,  EPA  and DOE understood
that future information  and  knowl-
edge gained from the actual opera-
tions  of the WIPP would  result  in
changes to the best practices and
procedures for  the facility. As such, a
process for identifying  and  evaluat-
ing  these  changes was established.
Key elements of this process are:
•  All potentially significant changes
   are proposed for EPA approval be-
   fore they are implemented by DOE.
•  DOE submits  annual change  re-
   ports  to  EPA that  identify  all
   changes,  both significant and
   minor,  that  were made to WIPP
   operations  or  plans during  the
   preceding year.
•  EPA reviews all changes to ensure
   we  have  no concerns regarding
   the performance of  the WIPP  or
   DOE's  continuing  compliance
   with disposal regulations.

Recertification  is a
More In-Depth Look at
Changes

  Every five years,  EPA conducts a
recertification of the WIPP to review
and conduct  a  more in-depth look at
the  collective effect of changes made
in the WIPP operations. As part of this
recertification:
•  DOE is required to conduct a new
   performance assessment in order
   to evaluate  changes to the facility
   and the environment and to reaf-
   firm that the WIPP meets all re-
   quirements of EPA's disposal reg-
   ulations.
•  DOE submits a recertification ap-
   plication to EPA containing the re-
   sults   of   the   performance
   assessment  and  identifying all
   changes and updates to the WIPR
•  EPA reviews this application in de-
   tail to assure that the WIPP will
   continue  to   safely   contain
   transuranic radioactive waste.
•  An approved application becomes
   DOE's commitment for how WIPP
   will be operated over the follow-
   ing five years.This application will
   then serve as the baseline for the
   next recertification in 2009.

Process  and Schedule

•  By law, DOE is required to submit
   a recertification application to EPA
   by March  2004  (five  years from
   the first receipt of waste at  the
   WIPP).
•  EPA will review the application for
   completeness and work with DOE
   to ensure that a complete applica-
   tion is received.
•  EPA is required to reach a recerti-
   fication   decision   within   six
   months  of receipt of  a complete
   application.
•  EPA will focus its review on areas
   of  change identified  by  DOE, in
   order to ensure that their effects
   have been addressed. Areas that
   have not been changed will be re-
   viewed to verify that they have
   not changed. DOE must demon-
   strate that it meets all aspects of
   the  disposal regulations before
   EPA will approve recertification.

Continued from previous page
•  EPA will base its recertifica-
   tion decision on the results of
   its ongoing oversight  of the
   WIPP  and on  DOE's applica-
   tion. At that point, EPA will
   submit  a  letter  to  DOE an-
   nouncing its decision.

How can you get
involved?
•  EPA will place all DOE sub-
   mittals  in the public docket
   and will solicit  public  com-
   ments on DOE's application.
   EPA will make sure that key
   information is available  on
   the web and at  EPA dockets
   and establish clear  proce-
   dures  for  submitting  com-
   ments.
•  EPA will be most interested
   in  public  input on  issues
   where  changes  have  oc-
   curred which may have a po-
   tential impact on the WIPP's
   ability to  remain in compli-
   ance with our disposal  regu-
   lations, as well as any areas
   where  the  public  believes
   that changes  have occurred
   at WIPP that have  not been
   identified by DOE.
•  EPA  staff   will   meet  with
   stakeholders after  receiving
   DOE's application to discuss
   issues of concern to the pub-
   lic before we make a final de-
   cision.
•  EPA will share  its decision
   with the public through  an
   announcement emailed to in-
   terested stakeholders, the
   EPA WIPP website and  a no-
   tice in the Federal Register.To

                                         Focus On Remote-Handled Waste
                                     DOE Seeks Approval for
                                     Remote-Handled
                                     Transuranic Waste

                                        The EPA is making a preliminary de-
                                     cision that is the first step in implement-
                                     ing   disposal   of   remote-handled
                                     transuranic (RH-TRU)  waste  that was
                                     previously approved as part of the waste
                                     disposal inventory for the Waste Isola-
                                     tion Pilot Plant (WIPP). Remote-handled
                                     waste  requires special  handling and
                                     modified waste characterization proce-
                                     dures because, unlike most WIPP waste,
                                     its  radioactivity  is  not  effectively
                                     shielded  by the waste  containers.  In
                                     EPA's 1998 Certification Decision (which
                                     allowed WIPP to open), the Agency ex-
                                     amined the amount and type of remote-
                                     handled waste that were projected to be
                                     disposed in the WIPP. The performance
                                     assessment and verification  conducted
                                     for the certification demonstrated that
                                     the WIPP can safely  contain RH-TRU
                                     waste. However, RH-TRU waste has not
                                     been  disposed at WIPP since its open-
                                     ing.  Before RH-TRU  waste  may  be
                                     placed in WIPP  for disposal, EPA  re-
                                     quires the Department of Energy (DOE)
                                     to demonstrate that generator  sites can
                                     adequately characterize and  track RH
                                     waste.

                                     Preliminary Approval of
                                     Framework for Charac-
                                     terization of Remote-
                                     Handled Waste

                                        After years of  development,  with
                                     input from EPA, DOE is now requesting
                                     EPA's approval of its plan to character-
                                     ize remote-handled transuranic waste.
                                     This is DOE's first step towards dispos-

                                     Plan  and the Waste  Characterization

                                     (WCPIP), Revision OD.
   EPA's December 19, 2003 letter to
DOE outlines our preliminary decision
to approve  the RH Waste  Characteriza-
tion  Plan and  Implementation Plan. It
also describes the approval process for
waste generator sites to characterize RH
waste for disposal at  WIPP.  The letter,
Waste Characterization Plan, and Imple-
mentation Plan are available online in
Adobe .pdf format—please check  our
website   (http ://www. epa .gov/radia-
tion/wipp) for more details.
   EPA believes that DOE's Waste Char-
acterization  Plan  and Implementation
Plan provide an appropriate  general
framework  for  conducting  RH  waste
characterization   activities.   We   are
proposing to approve both plans, which
would  allow DOE to proceed with de-
veloping  site-specific  characterization
plans for RH waste. This proposed ap-
proval  does not authorize DOE to char-
acterize or ship RH waste to the WIPP.

Future Approvals for
Waste Generator Sites
to Implement RH Waste
Characterization

   In order to obtain authorization from
EPA to conduct RH waste characteriza-
tion, shipment and disposal from waste
generator sites, DOE must  submit docu-
mentation specific to each of the waste
generator sites to  show the requirements
in the  Waste Characterization Plan  and
Implementation  Plan  have been  fully
met. Each site must also be inspected by
EPA to evaluate whether it  is adequately
implementing the site-specific RH waste
characterization programs.  The Agency
will follow the 40 CFR 194.8 or 194.24
inspection process as appropriate.  EPA
will make the site-specific waste charac-
terization plans  and inspection reports
available in the WIPP dockets and on its
website. The website will also announce
opportunities  for  public  comment on
our waste characterization activities. You

   EPA's WIPP Team is committed to a
thoughtful,  transparent process with the
public. Until January 30, 2004, we are
asking for your comments on our deci-
sion to approve the general framework
for RH waste characterization (DOE's
RH WC Program  Plan and RH WCPIP
[Revision OD]). We are interested in your
views on whether the Waste Characteri-
zation  Plan and  Implementation Plan
address the necessary components of
waste characterization, taking into ac-
count  worker exposures  to   radiation
and  other relevant factors. We also so-
licit your comments on whether the site-
specific  approval   process   contains
appropriate controls, and your sugges-
tions for any additional information EPA
should require in site-specific documen-
tation. We remind you that our prelimi-
nary decision relates to characterization
of RH-waste;  we are not reconsidering
the decision  to allow remote-handled
waste as part of  the WIPP  inventory.
Based on your comments, we may re-
vise  our  preliminary conclusion  or re-
quest further information. Following the
consideration of comments and any ad-
ditional information,  the  Agency will
issue another  letter  to  DOE  notifying
them of our final decision regarding the
RH Waste Characterization Plan and Im-
plementation  Plan.  The letter will be
made available to  the  public in our

Update on EPA's New
Electronic Docket IE-
DOCKET)

   In   the  last  WIPP   Bulletin,   we
announced  that EPA's new  electronic
docketing  system,  E-DOCKET  (http://
www.epa.gov/edocket),  was available
for use  by the  Agency and the general
public. Here is a review of the new sys-
tem, as well as some updates on EPA's
WIPP-related dockets.
   Anyone may use  E-DOCKET to access
an index of all available public  dockets
and view  current documents in Adobe's
portable  data file  (PDF)  format.  E-
DOCKET users can  search for a particu-
lar docket or document by title, release
date, document type,  Federal Register ci-
tation, program office, or other various
identifiers. You  can  submit comments
electronically as well. After  identifying
the docket or document on which you
wish to comment and agreeing to a pri-
vacy  and disclaimer notice,  you may
submit your comments online (using  an
electronic form provided on E-DOCKET)
or attach comments as an electronic file.
Providing your name, group, or organi-
zation is optional. After comments have
been  submitted, you  will receive a con-
firmation notice. Following a mandatory
review by docket staff (to screen for pro-
                                        fanity and other obscene material) your
                                        comment  will  be  published on  E-
                                        DOCKET  within three  business  days
                                        after receipt.
                                           EPA currently maintains four dockets
                                        for the WIPP program:
                                        •  A-92-56, which contains information
                                           about the WIPP compliance criteria;
                                        •  A-93-02, which contains information
                                           considered in making the WIPP certi-
                                           fication decision;
                                        •  A-98-49, which contains new infor-
                                           mation  that the EPA is continuously
                                           reviewing as part of the Agency's on-
                                           going oversight role at the WIPP; and
                                        •  E-DOCKET  #OAR-2002-0005,  which
                                           contains information regarding our
                                           proposed alternative provisions to 40
                                           CFR Part 194.

                                           Dockets  A-92-56   and  A-93-02 are
                                        closed and are not available on the  E-
                                        DOCKET system. Hard copies of all ma-
                                        terials contained in A-92-56 and A-93-02
                                        are maintained at each of our docket lo-

                                        cal guidance, and other correspondence
                                        related to the WIPP. In addition  to the
                                        paper copies that are housed in each  of
                                        the docket locations  listed above,  these
                                        documents can be viewed online. The  E-
                                        DOCKET  ID  for Docket A-98-49  is
                                        #OAR-2001-0012.  Because  the   EPA
                                        docket staff is still in  the process of back
                                        scanning material for all active  dockets,
                                        searching this particular E-DOCKET will
                                        bring up only a partial list of documents.
                                        We expect  the  E-DOCKET for #OAR-
                                        2001-0012 to be complete sometime  in
                                        early 2004.
                                           EPA  also  has established an  E-

                                        Although the comment period for this
                                        proposed  rule   has  closed,  interested

    Making Experience Count
Waste Characterization  Inspection
Process

   In our July  2002 bulletin,  we discussed EPA's proposed
changes to the WIPP Compliance Criteria. We're applying over
four years of oversight experience to improve our inspections
program and approval process.
   EPA issued the  proposed rulemaking  entitled "Criteria for
the Certification and Recertification of the Waste Isolation Pilot
Plant's Compliance  with the Disposal Regulations; Alternative
Provisions" (67  FR 51930-51946) on  August 9, 2002. Foremost
among the proposed changes were changes to the approval
process for waste characterization programs at Department of
Energy transuranic  (TRU) waste generator sites.  Other pro-
posed changes would add a process for making future minor
changes to the  Compliance Criteria, allow for the submission
of copies of compliance applications and reference materials in
a non-paper format (e.g., compact disk); and update terminol-
ogy related to waste characterization.
   A 90-day comment period was announced in  the Federal
Register, and public hearings were held in Albuquerque and
Santa Fe, New Mexico, on September 24-25, 2002. After con-
sidering all comments (which will  be  addressed in  our up-
coming "Response  to Comments"  document), EPA is now
moving forward with the final rule, and  expects to issue the
new Compliance Criteria provisions in early 2004.
   Most of the comments on our proposal related to  changes
in the DOE  waste  generator site  inspection and  approval
process, so we'd like to provide some information on the pro-
posed process that we expect will be finalized and begin being
implemented this fall. The process will be as follows:

t*~  EPA will conduct inspections  at all new waste generator
    sites and previously approved sites to establish a  baseline
    standard for waste characterization.  EPA inspectors will
    evaluate   equipment,   procedures,  and   personnel
    training/experience related to a range of waste characteri-
    zation components. After an inspection, EPA produces an
    inspection report to  describe its findings. Findings that  a
    specific item or activity is deemed inadequate usually re-
    quire  action by DOE to correct the problem and take steps
    to ensure it  does not recur. If the WC processes inspected
    are adequate to characterize waste for disposal at WIPP,
    EPA will issue a "baseline  approval" that allows the site to
    dispose of waste  at WIPP (once shipping and other re-
    quirements are met).
t*~  The baseline approval will specify any limitations on waste
    characterization  or disposal (such as  restrictions on what
    waste  streams may be disposed) and assign  specific re-
    porting requirements for all waste characterization compo-
nents and related activities. These changes and/or expan-
sions will be assigned to one of two categories ("tiers"), de-
pending on the required level of notification and approval
outlined in the site's  initial baseline approval. Tier 1 waste
characterization activities at a site will have more stringent
reporting requirements (e.g., require notification by DOE
and  approval by EPA prior to  shipment of waste  to the
WIPP) and will most likely  require  additional inspections
whenever any changes to that activity are made.  Tier 2 ac-
tivities will have more  moderate reporting  requirements
and EPA may approve changes to certain activities without
a follow-up inspection (i.e.,  desktop review  and approval
of certain technical documents). We will specify  the limita-
tions associated with the assigned tier and suggest the type
of information needed for EPA review.
EPA will issue a Federal Register  notice after each of the ini-
tial baseline inspections. The public  will be asked to com-
ment  on  the  proposed  tier  levels and  reporting
requirements for each of the  waste generator sites. EPA will
post relevant information and  other updates concerning
these decisions on the WIPP website.
DOE will report any changes in equipment,  processes, or
personnel, based on their tier level, and certain changes
must be reported to EPA before their implementation. EPA
will then decide whether or not a follow-up inspection is
necessary  to  confirm and  verify  the  adequacy of any
changes to the  site's waste characterization program. EPA
may also conduct unannounced site inspections of items
not assigned to a tier if EPA determines a need based on
the available  information. Follow-up inspections will be
posted on the WIPP website and inspection reports will be
sent  to our WIPP dockets.
After a site has been approved and has an established base-
line,  EPA may decide to change the tiering  scheme for a
particular  waste  characterization component or activity.
The decision to revise tiers at a site  will be  made through
continued compliance inspections under the  authority of §
194.24(h). In the event of  this type of tier change,  the
Agency will notify the public in the following manner:
EPA  will announce  the  proposed tier  change(s) and the
reasoning  behind them in an inspection report.
Elevating an activity to a more stringent  tier (i.e.,  additional
DOE reporting requirements for that particular waste char-
acterization component or activity) will  be effective imme-
diately and the  site will  be expected to operate  under the
more stringent requirements without delay.
Before moving an activity to a less stringent tier, EPA will
solicit public  comment.  The site will continue to operate
under the  more stringent tier designation until public com-
ment can be considered. The basis to change the level of
oversight for an activity (i.e., tier designation) will be de-
scribed in our inspection report.
                                                                                                The WIPP Bulletin 7

Nuclear Quality Assurance Audits
    One important function of EPA audits
    and inspections is to ensure DOE
compliance with EPA's quality assurance
(QA) requirements. In  the WIPP Compli-
ance Criteria (40 CFR 194), EPA required
DOE to establish rigorous QA programs to
help assure that sound data and informa-
tion are used in operating WIPP and eval-
uating  its performance. Under our rules,
DOE's  QA  programs must meet the  na-
tional Nuclear Quality Assurance (NQA)
standards developed by the American So-
ciety of Mechanical  Engineers to be  ap-
plied to nuclear facilities throughout  the
United States.

What  is the purpose of the EPA's
quality assurance audits?
   Basically, the NQA standards require
that each nuclear facility have an on-site
organization that constantly monitors the
quality of operations at the site. These
organizations  must have sufficient inde-
pendence, authority and qualifications to
effectively  carry out  their role. Since
1997, the EPA has conducted more than
forty audits of WIPP-related facilities to
confirm the proper application  of  the
NQA standards.

What  is the scope of the EPA's
quality assurance audits?
   The NQA standards apply for all items
and activities that are important to  the
containment of transuranic  (TRU)-waste
within  the WIPP. This excludes activities
such as the transportation of the waste to
the WIPP  site, or the  containment  of
non-radioactive hazardous wastes within
the WIPP.  Therefore,  the scope of  the
EPA's QA audits is limited to the applica-
tion of NQA standards that pertain to the
containment of TRU-waste at the WIPP.

What  does EPA do during a QA
audit?
   At   each WIPP-related  facility,   the
EPA's audit team reviews documents, in-
cluding organizational charts, operating
procedures, test results, training records,
procurement records, inspection reports,
and approval forms; and interviews  QA
                                       staff and management to verify compli-
                                       ance with the NQA standards. A facility's
                                       QA Plan is reviewed to verify that the re-
                                       quirements of  the NQA  standards are
                                       properly  established  within the  plan.
                                       Then,  the  EPA  auditors verify that  these
                                       established requirements  are properly
                                       implemented by the facility.
                                          During  an audit, the EPA's team de-
                                       velops a list of findings and  concerns. A
                                       finding is a determination that a specific
                                       item or activity does not meet a require-
                                       ment under the NQA standards. A con-
                                       cern is a judgment that a finding may
                                       occur  in the  future. Near the end of the
                                       audit,  the team discusses the severity of
                                       each finding to assess its impact on the
                                       facility's QA Program.

                                       What comes out of an audit?
                                          The EPA team evaluates audit results
                                       and decides  whether  or not a  facility's
                                       QA Program is in compliance. The EPA
                                       then writes an audit  report. The report
                                       lists the information  reviewed  by EPA,
                                       describes  all finding  or concerns, and
                                       specifies what follow-up actions are nec-
                                       essary by DOE to correct any problems.
                                       Depending on the nature and severity of
                                       problems,  EPA may conduct additional
                                       audits soon afterwards to further assess a
                                       finding or to verify that  a  finding has
                                       been corrected. In other  cases,  we  re-
                                       quire DOE to provide written responses
                                       to  our report,  documenting how  prob-
                                       lems have  been addressed.

                                       What does EPA provide to the
                                       public?
                                          Before the first audit of a facility, the
                                       facility's QA Plan is made available to the
                                       public through  the   Agency's  public
                                       dockets. After every audit, QA audit  re-
                                       ports  are  also placed  in  the public
                                       docket. QA audit reports can be found in
                                       Docket A-98-49, Category II-A1. Techni-
                                       cal documents  related to  QA programs
                                       can also  be found in Category  II-A2.

Tracking  and Under-
standing  DOE's WIPP
Changes:  DOE's
Annual Change Report

   The  DOE frequently  adjusts  WIPP
plans and activities  to  increase  effi-
ciency, reflect new priorities, or address
new information.  EPA tracks and evalu-
ates  such changes  to make  sure  they
don't adversely affect WIPP's ability to
contain   radioactive waste  and  meet
EPA's regulations.  Under the WIPP Com-
pliance Criteria  (40 CFR 194), DOE must
immediately report to EPA  significant
changes  to  activities  or  conditions at
WIPP, especially those that could lead to
radioactive releases  that violate  EPA's
regulations. For less significant changes,
EPA requires that DOE submit an annual
WIPP Change Report,  which documents
any changes made to the WIPP program
during the previous year. EPA reviews
each  Change  Report  to  determine
whether  any of the changes are signifi-
cant  and could  potentially affect WIPP's
performance.
   On November 19, 2002, DOE submit-
ted its fifth annual WIPP Change Report
detailing changes that  occurred between
September 16,  2001, and  September 15,
2002. The  majority  of  the  reported
changes were to written plans and pro-
cedures   used  to  maintain compliance
with the Certification. We requested sup-
plemental information concerning waste
characterization inspections  at various
sites and an updated waste inventory
summary. We completed our review and
determined that the changes were  not
significant and that the  2002 Annual
Change  Report  was complete. We pro-
vided the results to DOE in August 2003.
Our  request for information, as well as
previous WIPP  Change Reports, can be
found in our recertification Docket A-98-
49 under Categories II-B2 and II-B3.
   Lastly, DOE  requested   and  EPA
granted  a change of reporting dates for
future Annual Change Reports. DOE pro-
posed to alter  the schedule to reflect a
reporting period of July 1-June 30 of the
next year. EPA concurred that the revised
reporting dates  would  accommodate
more detailed information and analyses.

Waste Generator Site Inspections: An Overview
 This provides an overview of the process that EPA uses to approve waste characterization activities at DOE WIPP waste
      generator sites. It takes into account the revisions to 40 CFR Part 194 that will be finalized in early 2004.
Introduction
  EPA regulations  governing dis-
posal of transuranic (TRU) waste at
the Waste Isolation Pilot Plant (WIPP)
require that EPA inspect and approve
waste  characterization  activities  at
the  Department  of  Energy (DOE)'s
TRU waste sites. Before waste is ever
sent to WIPP for disposal, EPA con-
ducts inspections at the generator
sites to verify that the Department of
Energy's  (DOE) waste  characteriza-
tion  program  in  place can measure
and track how much waste goes to
WIPP and what that waste contains.
EPA  staff then conduct  inspections
annually, or more frequently in cases
where  DOE   seeks  approval  of
changes  to  waste  characterization
components warranting new inspec-
tions. This document provides a gen-
eral  overview  of EPA's  inspections
program.

What Does EPA Inspect?
  EPA looks at TRU  waste site char-
acterization programs to ensure that
all waste going to WIPP will meet dis-
posal requirements  (i.e., the WIPP
Certification  Decision).  EPA regula-
tions  require  that  generator  sites
quantify and track the  amount and
type of material  in each TRU waste
drum destined for  disposal  at the
WIPR If, after  inspection, EPA  does
not  approve  the  characterization
process, the site cannot dispose of
the waste at WIPR EPA validates that
the DOE's equipment can detect what
it is intended to detect, that it is work-
ing  properly, and that it is operated
by  properly trained and  qualified
staff. EPA also seeks assurance that
appropriate programs are in  place
and meet national standards to verify
the quality of all work.
How Does EPA Conduct These
Inspections?
   Before visiting a site, EPA reviews
documents and  records  to  under-
stand site procedures and to identify
items and activities that are most im-
portant to evaluate in  person. EPA
visits  the generator sites to observe
operations  in   progress,  inspect
equipment, interview operators, and
review procedures. Depending on the
size and complexity of the operation,
multiple  inspectors  will work to-
gether to ensure important aspects of
the program are inspected.

Who are the Personnel at These
Inspections?
   EPA sends staff and contractors
with  technical expertise and experi-
ence suitable for the scope of the in-
spection. EPA inspectors are expert in
individual areas of the waste charac-
terization process. There  are  also
other parties  who conduct inspec-
tions  to  evaluate  compliance  with
other requirements or regulations.
While these activities are indepen-
dent of EPA's waste characterization
inspections, they are often coordi-
nated to  coincide with EPA inspec-
tions.  Quality   Assurance  (QA)
personnel from DOE's Carlsbad Field
Office perform a QA review of site ac-
tivities;  DOE  QA inspectors deter-
mine  whether the  site  has properly
implemented DOE's waste characteri-
zation procedures  and  whether the
resulting  data meets the data quality
objectives. EPA oversees  DOE's QA
activities  and will occasionally  ob-
serve QA reviews at sites. Staff from
New  Mexico  Environment Depart-
ment, a State agency regulating dis-
posal of  TRU  waste  mixed  with
hazardous waste at  WIPP, evaluate
   Waste Generator Sites
  The waste intended for disposal at
WIPP is currently at about 15 DOE sites
across the U.S. Some of the waste was
produced through past processing of
nuclear materials and production of
atomic weapons. Other waste is being
generated as these  sites are cleaned
up.
  Since the WIPP began operation in
1998, EPA has approved waste charac-
terization processes at the following
DOE generator sites:
•  Hanford Site, Washington
•  Idaho National Engineering and
   Environmental Laboratory
•  Los Alamos  National  Labora-
   tory, New Mexico
•  Rocky   Flats   Environmental
   Technology Site, Colorado
•  Savannah  River Site, South Car-
   olina

  EPA has also approved several sites
to  use the  Central Characterization
Project  (CCP),  a  mobile  characteriza-
tion facility that DOE has developed to
assist TRU waste generator sites with
complex waste characterization activi-
ties:
•  Argonne  National  Laborato-
   ries-East, Illinois
•  Nevada Test  Site
•  Savannah  River Site
  Sites  with  pending EPA  approval
include:

•  Oak  Ridge National  Laboratory,
   Tennessee
•  Other small generator/storage sites
•  CCP-Los Alamos National Labora-
   tory
•  CCP - Hanford
                                                                                    The WIPP Bulletin  9

acterization requirements.  Represen-
tatives   of   the   Environmental
Evaluation  Group,  an independent
non-profit technical oversight organi-
zation, may observe inspections re-
lated to WIPR

When Does EPA Conduct
Inspections?
   Every  generator  site requires an
initial baseline inspection by EPA be-
fore it  is approved to ship waste to
WIPR EPA inspectors evaluate equip-
ment,  procedures,  and  personnel
training/experience related to a range
of  waste characterization compo-
nents. If they are adequate to charac-
terize waste for disposal at WIPR EPA
issues a "baseline approval" that al-
lows the site to dispose of waste at
WIPP (once shipping and other re-
quirements are met).The baseline ap-
proval  specifies  any  limitations on
waste  characterization  or disposal
(such as  restrictions on what  waste
streams may be disposed) and  any
potentially  significant changes in  a
site's waste characterization program
that will  require  additional EPA in-
spections  and   approvals.  These
changes  and/or  expansions will be
assigned to  one  of two  categories
("tiers"), depending on the required
level of notification and approval out-
lined in the site's initial  baseline ap-
proval. Tier 1 waste  characterization
activities at  a site  will have  more
stringent   reporting  requirements
(e.g., require  notification by DOE and
approval  by EPA prior to shipment of
waste to the WIPP) and  will  most
likely require additional inspections
whenever any changes to  that activ-
ity  are made. Tier  2 activities  will
have more  moderate  reporting re-
quirements  and  EPA may approve
changes to certain activities without a
follow-up inspection (i.e., desktop re-
view and approval of certain techni-
cal  documents). EPA will specify the
limitations  associated  with the  as-
                                    signed tier and suggest the type of in-
                                    formation  needed for the Agency's
                                    review and approval. DOE will report
                                    any   changes   in    equipment,
                                    processes, or personnel, based  on
                                    the  site's tier  level,  and  certain
                                    changes must be reported to EPA be-
                                    fore their  implementation. EPA will
                                    then decide whether or not a follow-
                                    up inspection is necessary to confirm
                                    and verify  the  adequacy of  any
                                    changes to the site's waste character-
                                    ization program.The scheduling of in-
                                    spections is not done on a set basis,
                                    but  according  to availability  of  in-
                                    spectors and any other parties and
                                    the  readiness of equipment for  in-
                                    spection.  Advance  notice  by EPA
                                    varies accordingly. In addition, EPA is
                                    free to conduct  inspections  at any
                                    other time it deems that inspections
                                    of a particular site may be warranted.

                                    What is the  Result of These
                                    Inspections?
                                       EPA's goal for waste characteriza-
                                    tion inspections is to verify that the
                                    waste  characterization  processes  at
                                    the site function adequately. After an
                                    inspection, EPA  produces an  inspec-
                                    tion report to describe its findings.
                                    Findings that a specific item or activ-
                                    ity is deemed inadequate usually re-
                                    quire action  by DOE to correct the
                                    problem and take steps to ensure it
                                    does not recur.  For example, a few
                                    sites we might find that the tracking
                                    of Acceptable Knowledge (AK) data is
                                    inconsistently formatted  and/or  in-
                                    complete.  (AK is  the detailed history
                                    of the waste contents, processes, and
                                    origination.)  If problems with the AK
                                    data are identified, EPA does  not ap-
                                    prove the waste for disposal at WIPR
                                    Once DOE corrects  the  problems,
                                    EPA's inspection team returns to ver-
                                    ify that the AK data is adequate. If no
                                    further problems are discovered, the
                                    waste can  be approved for disposal.
                                      A typical  problem identified dur-
                                    ing Quality Assurance (QA) program
                                    inspections has to do with the inde-
                                    pendence  of the  sites' QA Organiza-
tions. The Nuclear Quality Assurance
standards require that each QA Orga-
nization  "report to a  management
level such that required authority and
organizational freedom are provided,
including sufficient independence
from cost and schedule considera-
tions." However, the EPA audit teams
find instances where the QA Organi-
zations have  not been  provided this
degree  of independence.  In  these
cases, EPA returns to the sites to ver-
ify that the problem is corrected and
the QA Organizations  are  provided
adequate independence.
   For our initial baseline inspections,
the inspection report will include pro-
posed  tier designations for specific
aspects and components of the site's
waste characterization program. This
proposed tiering scheme will outline
the changes and expansions to cer-
tain waste characterization  activities
that will most likely trigger additional
inspections by EPA.

What is DOE's Role in  the
Inspection Process?
   DOE notifies EPA of a site's desire
to characterize TRU waste  for  the
WIPP and its  readiness to undergo a
baseline  inspection. DOE also must
notify EPA when it makes changes to
an approved  site program. (Depend-
ing on their  significance, and how
they were categorized in the baseline
approval,  these   changes   could
prompt additional  inspections,  or
could simply  be  reviewed  and  ap-
proved by EPA after implementation).
DOE provides all relevant documents
(including site-wide  plans and equip-
ment-specific procedures) containing
the site's waste characterization plans
and  data quality assurance  proce-
dures.  DOE must provide full access
to personnel,  equipment, and  infor-
mation related to an inspection. Fol-
lowing inspection  and approval  by
EPA, DOE is responsible for correct-
ing findings and operating its sites in
accordance   with   these  certified
processes.

What Information Will EPA Provide
to the Public?
   EPA makes available to the public
a written statement of the scope of an
inspection, as well as site-wide plans
provided  by DOE  which  form the
basis for our  site  visit.  EPA also
makes public the inspection  report
which  documents the results  of our
inspection, including any  problems
identified during the visit. For the ini-
tial baseline inspection at a site, EPA
will also  issue a Federal Register no-
tice after the inspection but before is-
suing any approval for the site. The
notice will state the results of  the in-
spection, EPA's  proposed approval or
disapproval, and  any restrictions  on
the approval.  It  will also describe
what  changes  or expansions  in the
waste   characterization   program
changes  will  require further EPA  in-
spections and  approvals. Potentially
significant changes will be assigned
to one of two categories ("tiers"), de-
pending on the required level of noti-
fication and approval. EPA will  accept
and consider public comments on all
aspects of the baseline approval.
   Once  a  site has  been  approved
and  waste  characterization  tiers
have  been established,  EPA will
announce follow-up inspections  on
EPA's  WIPP  website.  Inspection
reports for these follow-up inspec-
tions  will continue to be  placed in
EPA's WIPP dockets as well.
   EPA may also decide to  revise the
tiering designations at  any site fol-
lowing the  initial Baseline Compli-
ance Decision.  This decision  will  be
based  on a variety of factors. Some
sites may have a harder time con-
verting to the  more robust inspec-
tions  regime, and certain aspects of
theirWC  program that were strong in
the past  may  need more intense
scrutiny. Conversely, certain sites will
undoubtedly improve  their  overall
performance as they become  accus-
tomed to the new system, and certain
aspects of their WC program will sub-
sequently require less attention.
   If EPA  believes that a change  in
tiering designation  is  necessary for
any aspect of a site's waste character-
ization program after the initial base-
line decision,  the Agency will notify
the public through  our website  and
dockets.
   Changing  an  activity to a more
stringent tier (i.e., additional DOE re-
porting requirements for that particu-
lar waste characterization component
or activity) will be effective immedi-
ately and the site will  be expected  to
operate under the more stringent re-
quirements without delay.
   Before moving an activity to a less
stringent tier, EPA will solicit public
   comment.The site will continue  to
operate under the more stringent tier
designation  until public comment
can  be  considered.  The basis  to
change the level of oversight for an
activity (i.e., tier designation) will be
described in our inspection reports.

How Can You Get Involved?
   You can  stay up-to-date  on EPA's
inspection  activities by visiting  our
WIPP website,where we will post up-
dates and other information regard-
ing any  upcoming  inspections  and
site-related  decisions. Also,  when
EPA is considering whether to ap-
prove  new sites to dispose  of waste
at WIPP, you can provide comments
on our proposed decision and have
input regarding what future program
changes  at  the site merit a greater
degree of oversight by EPA in the fu-
ture. As  previously mentioned,  EPA
will issue a Federal Register  notice
after the initial baseline inspection  at
each site and open an official com-
ment period. Instructions  on submit-
ting comments for these actions will
be included in each of these notices
and will be posted on the WIPP web-
site. Information about the scope and
results of follow-up inspections will
also be announced on the site and in-
spection reports will continue to be
sent to ourWIPP dockets.
  As  always, EPA will  accept com-
ments and questions on our inspec-
tions   or  other  WIPP  program
activities at any time. Please feel  free
to  e-mail  us  at  radiation.ques-
tions@epa.gov.

A  Look at  Human  Intrusion  into  the  WIPP,
 Focus on  Fluid  Injection
   In the last Bulletin, we discussed the role of human intrusion
   scenarios in assessing the performance of the WIPP. This
   time we will focus on a particular human intrusion event
that received much attention during certification: Fluid Injec-
tion. Fluid injection is the process of pumping pressurized fluid
through a borehole into the subsurface.
   There are a number of reasons why fluid injection takes
place: to dispose of unwanted fluids such as water produced
when oil is extracted, to dispose of waste water, to enhance oil
recovery, and to dissolve salt to produce potash or to create a
cavity to store  oil or gas.
   Water used in oil production is usually injected beneath the
Salado salt formation in the Delaware Mountain  Group forma-
tions. The  Delaware Mountain Group is more than 2000 feet
directly below the WIPP disposal level. The concern at WIPP
is that, under  some potential  scenarios, injected brine could
migrate from the injection zone, flow into the WIPP disposal
rooms, and transport radionuclides to various exit pathways,
such as other boreholes or through other geological formations
adjacent to the WIPP rooms.
   During the original certification, extensive analysis was done
by both EPA and DOE to evaluate the potential  impact of this
drilling practice. The EPA concluded that this scenario did not

need to be included in the certification performance assess-
ment because Fluid Injection does not occur near WIPP, and if
it did occur, it would not cause releases greater than those al-
ready considered in the performance assessment results.
  EPA will require DOE  to reevaluate this scenario for the
recertification in 2004 to ensure that it is not now occurring
near WIPP. EPA will also perform its own review to determine
if the  methodology used  in  the  original  certification
assumptions still holds true today. If this is not the case,  then
fluid injection may need to be included in the new performance
assessment calculations.
