      TO:  Waste Management Division Directors
           Regions I-X


      Last October, I established the Environmental Priorities
 Initiative (EPI) Task Force.  Its mission is to develop an
 approach to coordinate the RCRA and CERCLA programs to ensure
 that this Agency address the most environmentally significant
 hazardous waste contamination problems first.  One of its.first
 tasks was to determine the universe of possible EPI sites.  The
. EPI universe is made up of RCRA closing land disposal facilities
 and storage and treatment facilities.  These facilities may
 present hazardous substance problems which may require action
 under CERCLA or RCRA.  We have provided lists of facilities that
 we think constitute the EPI universe to your representatives on
 the Task Force for their review, so that a total universe can be
 identified.   It includes close to 5,000 facilities.   Approxi-
 mately 2,000 of these sites are already on CERCLIS.   Most of
 these have received CERCLA Preliminary Assessments (PA's) and
 some have received CERCLA Site Investigations (Si's).

    The remaining 3,000 facilities would be placed, in a phased
 manner, on'the CERCLIS list of facilities and could be eligible
 for Superfund action.  They also -would continue to be subject to
 RCRA action and authority.   The Superfund program has agreed to
 perform PA's for these EPI  sites on a phased-in schedule based
 on the environmental priority assigned to each facility.  The
 Task Force has developed a  method that Regions and states could
 use to assign priorities to facilities.   Assigning priorities
 should result in three roughly equally sized groups of
 facilities:   those ranked highest priority; those ranked medium
 priority; and those ranked  lowest priority.  The priority ranking
 will determine the order in which EPI facilities will be entered
 onto CERCLIS and receive PA's under CERCLA.

       The  attached paper  outlines  this  suggested method for
 assigning  priorities to sites  to determine  the order  in which EPI
 facilities will  receive Preliminary  Assessments.  Several of
 the Regions have their own way of  assigning priorities to such
 facilities and of managing that process,  such as through the
 Environmental Services Division.   We are  forwarding this
 information to you because we  believe that  it may be  helpful to
 those  Regions that have not developed a method for assigning
 priorities to these sites.   It is  based on  two criteria that the
 Task Force agreed should  be included in setting priorities:.the
 environmental sensitivity of the location and the facility's
 history of releases.   Any Region that is  interested in using this
 method or  that needs additional information on the attached
 material should  contact Ellen  Brown  of  my staff at 475-9848.

     This  process of setting priorities is  not designed to be
 resource intensive; the important  thing is  to roughly order
 facilities at the start of the PA  process.  I am hopeful that
 this prioritization can be completed this year.

     In addition,  I am attaching a copy of  a paper entitled "The
 Environmental Priorities  Initiative:  An Integrated Approach to
 Identifying and  Addressing Environmental  Problems."   This paper
 is designed to be.useful  in explaining  EPI  to the public and to
 State  officials.   I am sending it  to the  Regional Administrators
 as well.                  "                      •.''-:.

     Please feel  free to  give  comments  on these two items to
myself or  Elaine  Stanley,/Chairman of the Task Force.  The EPI is
 an important element in our FY '89 and  out-year program planning.
 It will, I  feel,  lay the  groundwork  for reconciling the priori-
 ties of our individual programs with the  agency's overall
 environmental goals.

             METHOD  FOR PRIORITIZING CERCLA  PRELIMINARY
                  ASSESSMENTS  AT RCRA FACILITIES
 Background

      This paper describes a method to assign priorities to RCRA
 sites that are to receive CERCLA Preliminary Assessments as part
 of the Environmental Priorities Initiative.  These RCRA
 facilities include closing land disposal facilities and storage
 and treatment facilities.  These facilities would be placed on
 the CERCLIS list of facilities where/ as a first step,  they would
 receive a Preliminary Assessment.   This paper outlines  a method
 for prioritizing preliminary assessments.

 Summary of Method

      The prioritzation scheme is based on  two general factors:
 environmentally sensitive location and history of releases.
 Several data sources exist for each of these factors.  Each
 Region should use at least one data source for each factor,
 preferably one that is either available or easy to obtain.  The
 outline of the method to be used to derive the final score for
 each  site is given below.

 Outline of Method

      Preliminary assessments would be prioritized based on an
 assessment 'of the potential hazard posed by each former RCRA
 facility.   Hazard would  be assessed based  on two criteria:

      o     Is the facility located  in an environmentally sensitive
           area?      .

      o     Does  the facility have a history of releases?

      Data  to assess the  facility against each criterion would be
drawn  from a variety of  sources.  Each Region would be  free to
use data  sources that  are  convenient or available.  Regions must
use at  least  one data  source for each of the two criterion,
i.e., environmentally  sensitive  location and history of releases.
One data  source,  among  five that may be ch-osen,  that satisfies
the first  criterion is  the DRASTIC ranking.   Regions may use one
or more of  the four alternative  data sources to  satisfy this
criterion.   For  the second criterion,  history of releases,
Regions may  choose  from  four data  sources.   Exhibit 1 summarizes
each data  source for each  criterion.

     Exhibit  2 provides  a  table  ranking each of  the two general
factors; environmentally sensitive location  and  site-specific
problems  (release  potential)  on  a  three-part scale.  Sites are
ranked with  respect  to environmental  sensitivity as being

                                               OSWER Directive  #  9932.0
 either  "Highly  Sensitive1/  "Sensitive1/  or "Not  Sensitive1,  and
 are  ranked  as having  eit.her  "High1/  "Medium1/  or "Low1  history of
 releases.   This results  in  a site  being  ranked within  one  of nine
 boxes as shown  in  Exhibit  2.  The  prioritization scheme  chooses
 the  sites with  the  higher  score  first/  i.e.  sites scoring  a  nine
 have the highest priority/  whereas sites scoring a one have  the
 lowest  priority.

 Example:  How to rank a  facility

     o    Determine the  characteristics  of the site with respect
          to environmentally sensitive  location  and history  of
          releases  using the various possible  data sources.

     o    Use Exhibit  2  to  determine which box best describes the
          characteristics  of the site.

     o    The score for  the  site is  obtained by
          putting  the  site  in one  of the boxes in
          Exhibit  2.

     The scheme presented  here would require an  average  of
 approximately 4 to  6  hours  per site  of  staff time to rank  each
 variable.   EPA  estimates that a  CERCLA  preliminary assessment
 itself  requires 40  to  60 hours.

 Review  of Data  Sources

     Appendix A contains an  explanation  of the acceptable  data
 sources for determining environmental sensitivity of the location
of the  facility.  We  have  included an assessment of how  easy it
 is to obtain the information as  well as  how  reliable it  is
 thought to be.

     Appendix B contains a  summary of discussions with Regional
personnel about Section 3007 SWMU  letters/ Facility Management
Plans (FMPs)/ and quality of information in  State or Regional
files.  These discussions took place via telephone; there  was no
attempt on our  part to verify the  information  we received.

                            REVIEW OF DATA SOURCES
 Drastic Hydrogeoloqie Assessments

      The DRASTIC ranking of a region's potential for groundwacer pollution is
 a very quick and easy  way to" establish an ordinal list of facilities based on
 hazardous potential.   The only requirements for doing a DRASTIC racing for a
 facility are the DRASTIC manual and the tJ.S. Geological Survey National Water
 Summary and/or the appropriate USGS 7-i1 quadrangular nap.

      DRASTIC was-developed by the National Water Well Association,  in
 cooperation with the  U.S. Environmental Protection Agency.  The purpose for
 the project was to create a method that would screen the groundwater  pollution
 potential of any hydrogeologic setting with existing information anywhere  in
 the United States.                       -     ;

      In order to perform a DRASTIC Indexing of a site,  one must first locate
 the site on a State or U.S. map.   By comparing this location with the map
 guide  provided in the DRASTIC user's manual, it is possible to identify which
 hydrogeologic region  contains the site.  The specific hydrogeologic setting
 can then be determined by using the National Water Summary, and/or  the United
 States  Geological Survey 7-t' quadrangular map of the site's location.
 Finally,  the user reads the DRASTIC Score printed at the bottom of  the chart
 that breaks down-the  score.

    -; The -DRASTIC process is a very quick way to evaluate and prioritize a
 site.   Once the initial materials are assembled,  the actual indexing  process
 tak'es about 15  minutes.   Gathering the correct maps and the su.-r^ary could  ca.ke
 a good  deal of  time for a Region  that does not have ready access to them.
 Discussions with the  USGS indicated that ordering of quadrangular maps  would
 have to be  done through the Denver office and they could not give a time
 estimate  on delivery.

     The  primary advantage to the DRASTIC system, in addition to the  short
 time it would  take to use,  is that the system gives an  ordinal ranking based
 on  ground water pollution potential.   The system is one that can be readily
 used by all the Regions  and would generate consistent and comparable  results
 provided  that  the  scorer(s)  were  somewhat familiar with hydrogeology.   People
 without a background  in hydrogeology would also be able to do the indexing but
 the results would  be  less reliable if the site specific settings were not
 identified  precisely.

Counties  identified through assessments of state officials:

     Region  III  prioritized 245 counties in that  region based on potential for
groundwater  and  drinking  water  contamination.   The prioritization of  counties
was based on the  rankings of  5  factors, listed below.

-------
                                                         OSWER Directive # 9932.0

                                      A-2
           Based  on the hydrogeology,  the  groundwacer availability was ranked
           as  'Sigh',  'Moderate',  and  'Low'.

           The  susceptibility for  contamination  is  ranked based chiefly on the
           history of  contamination, and  the  permeability of the area.

          .The.  percentage of the population served  by public water facilities
           that draw on groundwater.

           The  total population that draws on groundwater.

      •  •   The  total number of potential  sources  of contamination.

      Each alternative was ranked  on a scale  of  1-5, and the higher the total,
 the  greater the  environmental sensitivity.

      The  primary resources needed to  do  a similar  study are as follows.  The
 FERDS database of public water supplies,  along  with region and state-wide
 maps, which are  available, can provide adequate  data for the factors listed
 above.  A time estimate is not readily available,  however, the entire process
 should  not take  a long time, not  more than 1-2  hours per site, once  the data
 required  becomes available.  The  Region  III  method prioritizes inspections
 based on  groundwater.  This method could  be  expanded to include surface water,
 industrial density, or other factors. This  expansion will probably  be costly,
 though  'the results could be very  helpful  in  a more complete prior itization of
.counties.                  '                                '  •

 Location  near  densely populated areas

      According to the Hazard Ranking  System  (ESS), for groundwater and surface
 water,  a  radius  of 3  miles is defined as  the critical radius,  for populations
 in the  area of Superfund sites.  For  air, the critical radius  is  4 miles.

      Extensive population data exists in  the United States Census.   In
 addition,  a database, Geographic  Exposure Modelling System (GEMS) developed by
 the  Office of  Toxic Substances, provides  ready  access to many  other  models and
 databases.  This database has the ability to provide population densities, for
 any  radius around a facility, given  the  latitude and longitude of the
 facility.

      This  data,  if accurately obtained,  may  be  very useful.  Despite the
 uncertain  accuracy of the data for sparsely  populated areas, this data source
 could be  a potentially mandatory criterion.

 HVDHS release  data

      HWDMS is  a  dynamic database, that OSW created approximately  5 years  ago
 to keep track  of RCRA facilities.  The database contains  information on
 compliance status, permit status, whether a  facility  is a  generator,
 transporter, or  a TSD facility of hazardous  waste, and other  items.  The  data

 cover che universe of RCRA facilities.  Data on releases are usually available
 if inspection reports have been filed.

      The database is segmented, and consists of several records, hence,  it is
 easy to access even highly specific information.  To access the data and
 manipulate it, the EPA identification number, and the activity code number is
 needed.  These codes are. readily available within the database itself,  and in
 the HWDMS dictionary, v

      The quality of data available in this database varies significantly.
 Extensive and reliable data exist on land disposal facilities, however,  data
 on treatment and storage facilities are not as reliable.  Due to the
 uncertainty of the existence and reliability of data, this data source  should
 be optional until the database is updated.                          '

.Location near environmentally sensitive areas; e.g. wetlands,
 :  Great Lakes, Chesapeake Bay, etc.

      There are numerous ways for a region to define 'environmental
 sensitivity'.  The definition can be based on natural features such as
 wetlands,  lakes,  rivers,  etc.  In addition, there are various definitions  for
 these natural resources;  for example,  the U.S. Army Corps of Engineers  and the
 U.S.  EPA use one definition, whereas the Federal Executive Order 1190  provides
 another. .                              '                              , •

      Definitions of-' ' environmentally 'sensitive areas'  usually deal wich  areas
 having  saturated soil conditions such as swamps, marshes, bogs, and other
 similar areas.  Other potential 'environmentally' sens itive areas'  are  major
 rivers,  lakes, bays,  and  other similar areas.  Another possible way of
 defining  'environmentally sensitive areas', is by having the EPA Regions
 determine  areas  similar to the ones described above,  that need to be
 preserved.

      Because of  the  various definitions and nature of 'environmentally
 sensitive  areas,'  there is very little data available that can be used  on  a
 national basis.   However,  data such as maps of states, showing the physical
 features,  the underground soil and rock features,  do exist in the National
 Water Summary.   Once  'environmentally sensitive areas' are defined, it  may be
 possible to  get  the  relevant data.  Due to the numerous possible definitions,
 the data are hard to  obtain,  variy significantly,  and are of uncertain
 accuracy.  Owing  to  the uncertainty of the data, this data source should be
 optional.

Location near public  water  supply  intake

     The proximity of a  facility to a public water supply is potentially a
useful criterion  in a prioritization scheme.  EPA created a database called
the Federal Reporting Data  System  (FRDS), of Public Water Systems (PWSs), that
is administered by the Office of Drinking Water.  Using this database, it is
possible to findTout  the  number and distribution of PWSs, within any radius of
the facility^." This data, should however/ be used carefully because the public
water systems are not all groundwater sources but are sometimes the water
treatment plants.  The data  contained in this database are sometimes
inconsistent, e.g., if the  exact location of the PWS is not determined, then
the PWS is shown at the  central point of the zip code in which it exists.  In
additional, it was found  that more than half of the PWSs have no source data
and nearly two-thirds of  the sources have invalid/missing data.  Also, the
latitudes and longitudes  as  used in the FRDS database are limited to degrees
and minutes which can represent an inaccuracy of as much as one mile in
latitude and 0.75 to  0.95 miles in longitude.'

     This database is readily available.  However, owing to the variable
accuracy of the data, this  data source should be optional.

    THE ENVIRONMENTAL PRIORITIES  INITIATIVE: AN INTEGRATED
APPROACH TO IDENTIFYING AND ADDRESSING ENVIRONMENTAL PROBLEMS
 Introduction: The Environmental Priorities Initiative

      The Environmental Priorities Initiative (EPI)  is a new
 approach to managing environmental problems, particularly at
 RCRA facilities.  It is an integrated RCRA/CERCLA effort
 that will enable the Agency and the States to identify,
 evaluate, and cleanup first those sites that present the
 greatest threat to human health and the environment.
 Why Is An Integrated Management Approach Needed?

     It is imperative that EPA address the worst
 environmental problems first.  .However,  our current approach
 often precludes this.   We sometimes handle sites reactively
 as  they become the subject of public concern and we 'may not.
 always respond to .the worst environmental problems first..
 The public highlights such situations when the site
 threatens the surrounding community's health and well-being,
 a point well past the reach of changes in facility
 management,  preventative measures or early corrective
 action.

    Also,  the Agency does not always deal with our nation's
 worst environmental problems first because it tends to
 address cleanups on a program-specific basis.   That is,
 there is  a tendency to use only those authorities available
 under a single program's authorizing legislation.   As we
 address facilities, we can enhance our effectiveness  if we
 do  not limit our approach to only those  authorities
 available under a single program.   EPI is based on the
 belief that  the Agency should  use whichever authorities are
 available — including a combination of  RCRA and CERCLA
 authorities  -- to achieve cleanup at a site.

      Until  recently we have focused our  resources on
 permitting  and requiring corrective action at land disposal
 facilities  and incinerators,   consequently,  the RCRA program
 has not systematically addressed corrective action needs in
 other  segments of the  Subtitle C universe,  such, as closing
 land  disposal   facilities and  most storage and treatment
 facilities.  Many of these facilities may present serious
 threats to human health and the environment.   Although
 closure plans  for some of these facilities may be submitted

-------
                                            OSWER Directive # 9932.0
 and  approved by FY 1989,  the  reality  is that the extent of
 corrective action needed  at many  if not most of these
 facilities may not be determined  until well into the 1990 's.
 We must  begin to address  facilities that need corrective
 actions  or closure to prevent serious threats to human
 health and the environment.
As  an Agency,  we  need to  develop  a management scheme that
will enable  us to target  our  cleanup  efforts at sites with
the most  serious  environmental  problems  first.  Superfund
includes  a process to screen  a  large  number of sites to
determine which sites present the most serious environmental
problems.  By  applying this process to certain RCRA sites,
the RCRA  sites that present the worst environmental problems
can be  identified systematically  for  priority action.
Through the  use of joint  RCRA and CERCLA corrective action
authorities, sites can be addressed quickly and efficiently
—  to prevent  facilities  from becoming tomorrow's Superfund
sites.  The  creation of such  an integrated process for
assessing and  cleaning up RCRA  sites  is  consistent with the
Agency's  mission  to protect human health and the
environment.
The Universe of  Sites To  Be Addressed Under EPI

   The Agency has  identified  a. large universe of sites that
may require corrective  action for hazardous waste
contamination  under the  authority of RCRA or Superfund.
Initially EPI will  focus  on the following types of
facilities:

   o    Operating RCRA  storage and treatment facilities;

   o    Closed or closing RCRA storage, treatment, and land
        disposal facilities;  and

   o    Ninety-day.accumulators— generators officially
        included in the RCRA  universe as storers.

   Operating RCRA  incinerator and land disposal facilities
also may require corrective action, but are currently being
addressed as a priority under RCRA.

   There are additional types of sites that may merit this
focused integrated  RCRA/Superfund management approach that
the EPI is now applying to Subtitle C RCRA facilities.
Examples of such facilities might include Subtitle D
facilities, facilities  that store, treat, and dispose of
PCB's, or certain underground storage tanks.  In the future,
the Agency will consider  how  it can best apply the EPI

-------
                                             OSWER Directive it 9932.0
principles to  such facilities to ensure that we address the
worst environmental problems first and use RCRA and CERCLA
authorities in an integrated way to achieve effective and
expeditious clean-up.

How EPI Will Work

   The EPI would enable the Agency to address facilities,
such as closing RCRA facilities, that otherwise would not be
addressed for some time, under current Agency priorities.
The EPI will:

   1.    Require a streamlined, priority-setting mechanism
        for RCRA closing land disposal and storage and
        treatment facilities to determine for which
        facilities an assessment should be performed, and in
        what fiscal year.   This screening process could be
        implemented at the Regional or State level, using
        approaches most appropriate and efficient for each
        Region.'  Several Regions have expressed a desire to
        take a more integrated approach to directing
        resources toward the most environmentally
        significant facilities.  Effective ways are  needed
        to identify these facilities and some    Regions
        have begun already to establish priorities based on
        potential threats to human health and environmental
        significance.                     .

   2.    Enable the Agency to conduct Preliminary Assessments
        ("PA's")  at RCRA storage and treatment and closing
        land disposal  facilities which are not on a
        permitting path.   The PA's will provide information
        to allow  an estimate to be made of environmental
        significance.   This estimate would include a
        preliminary score  based on CERCLA's Hazard Ranking
        System ("HRS").   Those  sites that do not meet the
        HRS  cut-off  will  be removed from the EPI universe
        and  put back in the RCRA queue.   Most of the
        remaining facilities will receive an SI/RFA.   The
      .  SI/RFA will  be  comprised of the elements of a
        Superfund SI under CERCLA and a RFA under RCRA.
        Once performed  the SI/RFA will provide a basis for
        permitting  or enforcement action.
  3.   Provide a process  by  which  the  Regions  and  States
       can determine  an appropriate  enforcement  strategy
       for a site using authorities  available  under  RCRA

-------
                                             OSWIR Directive # 9932.0
         and/or  CERCLA to  assure  that a site is cleaned up.
         If  an owner/operator  is  unwilling or unable to
         perform corrective  action, clean up of the site
         under CERCLA would  be considered.1

   In summary,  the  Environmental Priorities Initiative (EPI)
will enable the Agency to determine which sites pose the
greatest environmental threat and deal with those sites
quickly  and effectively by  using the authorities that work
best for the particular site.
           facilities  for which corrective action
authorities are available,  are not eligible for listing on
CERCLAfs National Priorities List  ("NPL") unless the Agency
determines that RCRA corrective measures are not likely to
succeed due to one or  more  of the  following factors:

   (1)  The owner/operator  is bankrupt;

   (2)  The owner/operator  has lost authorization to operate
        and his compliance  history indicates an
        unwillingness  to perform corrective action; or

   (3)  The owner/operator  is unwilling to perform
        corrective action,  to be determined in a case-by-
        case basis.

     The agency will publish a policy notice defining the
criteria by which it will determine that an owner/operator
is "unwilling" in the  future.
