CHAPTER  1:  PROJECT SUMMARY
   Congress passed  the  Comprehensive
Environmental  Response,  Compensation,
and  Liability  Act (CERCLA)  in  1980  to
address the environmental threats posed by
the  nation's  uncontrolled  waste  sites.
CERCLA directed the U.S. Environmental
Protection Agency (EPA) to  identify the sites
that  pose the  greatest relative danger  to
human  health or  the environment.   In
response, EPA developed a site assessment
process to evaluate and screen sites within
the  Superfund  program.     The  main
components of the site assessment  process
(see  figure on next page) are:

   CERCLIS.   The  CERCLA  Information
   System (CERCLIS) is EPA's data base to
   record and track activities  at  all sites
   discovered. EPA learns of sites  in many
   ways, including federal  programs, state
   and  local   programs,  and   citizen
   notifications.

   Preliminary Assessment.  EPA or the
   state conducts a preliminary assessment
   (PA) at every site entered into CERCLIS.
   The PA — a relatively low cost review of
   available information — determines if the
   site  warrants further CERCLA action.
   After the PA, EPA decides either to send
   the  site  forward  in the  assessment
   process or to  classify the site as NFRAP
   (no  further  remedial  action   planned
   under CERCLA).

   Site Inspection. The site inspection (SI)
   involves more detailed  data collection,
   including   environmental  sampling.
   Based   on  the   SI,   EPA   either
   recommends  scoring the  site with the
   Hazard   Ranking  System  (MRS)  or
   classifies the site as NFRAP.

   Hazard  Ranking System.  The MRS
   uses information gathered during the PA
   and  SI  to screen  and identify  sites
   consistently for the National Priorities
   List  (NPL).   The  HRS  results  in  a
    numerical  score  that  is used to set
    priorities   for   more   detailed   site
    investigation. In general, sites scoring
    28.50 and above are added to the NPL,
    and  sites  scoring  below  28.50  are
    classified as NFRAP.

    National  Priorities  List.   The  NPL
    identifies sites that warrant more detailed
    evaluation   and   possible  remedial
    response.  Adding sites to the NPL is a
    rulemaking process — sites are proposed
    for the NPL in the Federal Register, the
    proposal is subject to public comment,
    and those  sites with HRS  scores that
    remain   above   28.50  after  public
    comment become final  NPL sites.

    This report is one in a  series providing
information on the nature of the sites being
evaluated by the Superfund site assessment
program.   It  is  intended to  provide  a
"snapshot" of sites in Region 10 on the NPL
as of February 1991.  Separate reports are
available for the other nine EPA Regions and
for the nation as a whole.  Other reports in
this   series   cover  the  CERCLIS
characterization  project,  which  provides
representative information on the types of
sites in the CERCLIS  inventory.  National
and  Regional  CERCLIS  characterization
reports also are available.
1.1    PROJECT OBJECTIVES

   In 1989, EPA undertook a  project to
characterize sites on the NPL. The project's
main objectives were to:

•  increase   understanding   of   the
   characteristics of NPL sites;

•  develop a centralized repository for NPL
   site information; and

•  summarize  the  types  of   sites  the
   Superfund program is addressing.

-------
    Because the characterization is based
on   information   collected   during  the
screening stages of the Superfund process,
it  does  not  represent  a comprehensive
characterization  of NPL  sites.   The site
assessment program is a screening program
— hundreds of sites pass through the PA and
SI stages annually. EPA's understanding of
sites  may  change  after  more  detailed
investigations  are conducted during the
remedial stage of  the Superfund process.
The figure  on the previous page illustrates
the position of the site assessment stage in
the context of the overall Superfund process.
This report provides  a  summary  of the
characteristics of NPL sites in Region  10 as
they are understood at the time of listing.
1.2    GENERAL METHODOLOGY

    The   NPL   characterization   project
evaluated 1218 sites — the 1189 sites on the
NPL as of February 1991 plus 29 sites that
have been deleted from the NPL because all
appropriate  response actions have  been
taken.   (Four sites deleted early  in  NPL
history were not included.)  The 79 sites that
were proposed for the NPL but subsequently
dropped from further consideration were not
included. The proposed sites were dropped
because  of  policy  issues or because their
MRS scores fell below 28.50 (the cutoff point
for listing) after public comment.

    The table below indicates the number of
sites  in   each  EPA, Region that  were
reviewed.  Of the 69 sites located in Region
10,  one had been deleted as of February
1991.

    EPA published  the original MRS  on July
16,  1982  (47 FR  31180). The  Superfund
                         Amendments and  Reauthorization  Act of
                         1986 (SARA) required EPA to revise the MRS
                         to assess more accurately the relative risk
                         posed by waste sites. The revised MRS was
                         published on December 14, 1990  (55  FR
                         51532).   The NPL  characterization  project
                         evaluated the complete set of sites that were
                         listed based on the original MRS (with the
                         exception of four  deleted sites  as noted
                         above).   Sites listed on the  basis of the
                         revised MRS were not evaluated.

                             Data for the NPL characterization project
                         were collected in two stages.  First, the final
                         MRS package for each site (filed at the EPA
                         Headquarters  Superfund   Docket)  was
                         reviewed.  Then, any data  gaps were filled
                         by reviewing the Regional site files.
                         1.3    RESULTS

                            The results of this report are presented
                         in  chart  form in  Chapters 3  through 9.
                         These charts include information about: site
                         description, owner/generator, regulatory and
                         response  history,   MRS   scoring,   waste
                         description, site environment, and water use.
                         The box  at  the bottom  of the  next  page
                         provides  information to assist the reader in
                         interpreting the charts.

                            Listed below are notable findings of the
                         NPL characterization project for Region 10.

                         •  Slightly less than a third of NPL sites in
                            Region 10 are located  in rural areas;  a
                            third  are located in urban areas (Chart
                            1).

                         •  Over   half of  Region  10  NPL  sites

Over 40% of  NPL sites in Region  10
contain   wastes   generated    by
manufacturing industries (Chart 10).

About 45% of Region 10  NPL sites were
identified  through   state  and  local
programs (Chart 17).

Two-thirds of  NPL sites in Region  10
have released hazardous substances to
ground water; more  than a third  have
released   hazardous  substances  to
surface water (Chart 23).
•   A third  of Region  10 NPL sites have a
    sensitive  environment  within 3  miles
    (Chart 33).

•   Over 90% of Region 10 NPL sites have
    operable wells within 1 mile (Chart 39).

1.4    ORGANIZATION OF DOCUMENT

    This document consists of nine chapters
and three appendices.  Chapter 2 provides
more detailed information on data collection
activities and includes the data collection
form and instructions.  Chapters 3 through 9
present the results in chart form.  Appendix
A lists all of the individual responses for the
"other" response category, which  are  not
displayed  separately   on  the   charts  in
Chapters 3 through 9.  Appendix B lists the
sites reviewed, and Appendix C contains a
map that shows the locations of these sites.
                       INFORMATION ABOUT THE CHARTS

   Data were generated from a review of NPL site files in 1989. Except where noted, charts depict
   information for all 69 sites reviewed in Region 10 — 68 that were on the NPL as of February
   1991, and one that had been deleted because all appropriate response actions have been
   taken.

   Efforts were made to characterize site conditions/surroundings as they existed at the time of
   the MRS score. The HRS scoring package and associated references served as the primary
   information source.

   Percentages on some charts do not total exactly 100 percent due to rounding.

   Percentages on some bar charts total to greater than 100 percent because multiple responses
   to certain questions were possible.

CHAPTER 2:  DATA COLLECTION  METHODS
    Before the NPL characterization project,
information on  Region  10 NPL sites was
available in individual  site  files at  EPA
Headquarters and the Regional office. The
project compiled and centralized site-specific
information on the characteristics of these
NPL sites.  This chapter describes the data
collection activities.  The table on the next
page summarizes the  process  used to
collect data.
2.1    DATA COLLECTION
       PROCEDURES

    After developing the overall approach to
the  NPL  characterization  project,   EPA
prepared a data collection form (see Section
2.4). The  design of the form was based in
part on the form  used  for the CERCLIS
characterization   project,   an  earlier
companion project.  A few new questions
were added and some existing questions
were modified to capture information more
pertinent to a study  of  NPL sites.   An
instruction manual  (see  Section 2.5) was
developed  to  promote  consistency  and
accuracy  in data  collection.    The  data
collection  form  and  instruction  manual
should be  consulted for a full explanation of
the definitions  used in the report.   Data
collection procedures were tested on Region
10 sites.   As a result,  a  few modifications
were made to the data collection form. The
modified form, as shown in Section 2.4, was
used in the other nine Regions.
stage of the data collection  process by
reviewing  MRS  scoring  packages at the
Headquarters  Superfund  Docket.    The
second stage involved filling in data gaps at
the Region 10 office.  Information reviewed
included  HRS scoring package reference
documents such as SI reports, PA  reports,
maps, and records of  telephone contacts.
After data for all Regions were collected and
verified,  the  project team compiled  one
national data base. The data base was then
analyzed to calculate response frequencies
for each of the data fields.
2.3    QUALITY ASSURANCE/
       QUALITY CONTROL

   The first level of quality assurance/quality
control (QA/QC), conducted at the Regional
office,  involved comparing  the information
collected at EPA Headquarters with the
information  available  in  the  Region and,
where  necessary,  resolving  differences.
After information on the data collection forms
was  entered into the data  base, the data
base  was  reviewed  to  ensure that the
information  had been properly transferred.
A second level  QA/QC involved reviewing
the   data   base   for    completeness,
consistency, and accuracy.  In addition, the
graphics  produced for this and all  other
reports were checked for consistency with
the data base.
2.2   SOURCE OF DATA

collection form could be answered in the first

2.5   DATA COLLECTION FORM INSTRUCTIONS1

      The NPL Statistics Data Collection Form has been designed to standardize hazardous
waste site information for input into a data base.  This data base will be used to perform a
statistical characterization of waste sites on the NPL.  All proposed and final NPL sites will be
reviewed for data compilation, including former final sites  deleted from the NPL because the
Agency determined that no further response was necessary. The NPL Statistics Data Collection
Form is designed so that all required information can be obtained by a review of the MRS
package and supporting materials contained in Regional EPA NPL files.

      It is important that all questions on the form be answered even if the appropriate answer
is "unknown." Estimates based on best professional judgment are allowed, but hard  data are
preferred.  In some cases, the response "other" can be used along with a brief narrative if the
available choices do  not adequately describe the site or situation.  Additional information to
support the use of this category should be included in the "Comments" section at the end of the
form. RESPONDENTS ARE ENCOURAGED TO USE THE "OTHER" CATEGORY AS MUCH AS
NEEDED.

      The Data Collection Form contains six sections which are listed below. The name of the
file reviewer should be written on the front in the top margin.  The form should be completed in
dark pencil so that later QA/QC corrections  to the form  will still result in an easily legible
document for data entry purposes.

      Section 1 - Record Information, which provides basic identification information;

      Section 2 - Site Description, which describes the ownership, status, and history of the
                 site;

      Section 3 - Waste  Description, which describes the  types and quantities of wastes
                 present at the site;

      Section 4 - Environmental/Demographic Information, which provides information on water
                 supply, population, and environmental damage;

      Section 5 - Regulatory and Response History, which covers any regulatory activity that
                 occurred prior to CERCLA involvement and includes RCRA status;

      Section 6 - Comments, which provides space for a brief description of the site, including
                 a list  of contaminants  and comments  on data availability or associated
                 problems with completing the form. Explanations of "other" responses should
                 also be given here.

Section 1 - Record Information

      1.    Site  Number: This is the number by which the site will be identified in the data
           base.  It  is essential that this  number be entered correctly on the form. The Site
           Number is the seven digit, Regional ID number for that site, usually marked on the
   1 This section is a slightly edited version of the actual instruction manual that
accompanied the data collection form.
                                         11

-------
            MRS  scoring package cover page.  In the case of some  proposed sites, an ID
            number indicating the Update Number is given and should be used. When entering
            the Site Number, it is required that the commonly accepted two letter abbreviation
            for the state's name precede the Regional ID number (or other number) for the site.

            NOTE:      If no identification number is available,  use any reasonable means of
                       numbering, but  remember  to precede the number  with the  state
                       abbreviation.

      2.     Site Name:  This is the name of the site as  identified  on the NPL  Copy the
            complete name of the site in the space provided. Also, enter the location of the site
            (town/county and state) directly below the site name.

Section 2 - Site Description

      1.     Coordinates: Enter the coordinates, latitude and longitude, of the site in degrees,
            minutes, seconds, and tenths of seconds. If tenths of a second are not given, enter
            zero as a default value in the appropriate space. If no coordinates are available at
            all, leave blank and mark "unknown," while specifying site location (eg., township
            and range) in the collection form's "Comments" section.  Because latitude and
            longitude provide necessary  input for  interaction with  other data bases, it is
            particularly important that these values or descriptions be included.

      2.     Setting: Setting is a qualitative measure of population density near the site.  Mark
            the appropriate box to indicate the character of the area surrounding the site.
            "Urban"  indicates central  city areas, "suburban"  indicates  sites bordering  or
            surrounding urban areas, and "rural" indicates sites outside suburban areas. Select
            the one setting that best describes the site. This information may be derived from
            an accompanying map.  Generally, the number of homes and/or industrial buildings
            indicated on a map may be used to estimate the site setting.  Since the character
            of the area is relative to population density, a site in the center of a city such as
            Roanoke Rapids, which is  located in rural North Carolina,  would be classified as
            "urban."

      3.     Location Land Use/Site Use: The predominant land uses  within approximately 1
            mile  of the site location should be determined and all appropriate descriptions
            identified.  If the land immediately adjacent to or on site is  used for activities
            associated with large numbers of people, or a  sensitive environment which could
            increase the risk posed by the site, describe the appropriate  land/site use in the
            "other" category. Examples of "others" include:

            • railroad                         • school/college
            • airport                          • harbor/marina
            • sports complex                  • federal/state park
            • wetland

            Mining, military, or DOE should be checked only if  they correspond to actual site
            use or immediately adjacent site use.   Additionally, if  the site  or area had a
            predominant historical usage (e.g., railroad yard, landfill, power substation), identify
            this in the "other" category  with the words "past" or  "previous."
                                          12

-------
4.     Current Ownership:  Check one appropriate box to indicate the type of ownership
      of the site at the time of the MRS score. For purposes of this data field, operators
      may  be characterized as "owners" if ownership distinctions are not made.   For
      consistency, treat the following situations as detailed below:

      •     If ownership/operation is by multiple individuals, businesses,  or industries,
            indicate "other" and state the condition. However, if all owners  belong to the
            same category, it is not necessary to put this under "other;" simply check the
            appropriate category.

      •     When  the  site  is  a  contaminated ground water plume,  as  defined by
            contaminated wells, mark "other"  and enter "contaminated ground water
            plume."

5.     Ownership When Contaminated:  Check the appropriate box to indicate the type
      of ownership at the time the site was contaminated. As in item #4, ownership refers
      to owner and/or operator if a  distinction  is not  made.  Procedures for ownership
      when contaminated are similar to current ownership.

6.     Area of Site: Indicate the area of the site, along with the appropriate units.  The
      area  of the site includes the "source" of the waste and the area that  has come to be
      contaminated. If the area of the site is reported as a range, use the midpoint of the
      range. Again, this data field is intended to capture the area of contamination.  So,
      for example, if there is a large facility but only a small area is actually contaminated,
      only  the area of  contamination should be entered.   If  the specific area  of
      contamination is unknown, use the area of the  facility, if reasonable (use  best
      professional judgment), and note this in the "Comments" section. For  ground water
      contamination plume sites, area refers to the planar area of the plume. Generally,
      the area of the site will be given in the narrative that accompanies the MRS scoring
      package.

7.     Site Status:  Check the appropriate box to indicate the status of the site at the time
      of the MRS score.  Sites  are to be considered "active" if waste treatment, storage,
      or disposal activities are taking place at the time of the MRS score.  These activities
      do not necessarily  have  to be those that resulted in the site being considered for
      the NPL. Sites that have changed ownership  or  operations are  still  considered
      "active" if the new operations possibly involve hazardous materials/wastes. "Inactive"
      sites  are those at which treatment, storage, or disposal activities no longer occur.
      For consistency, address the following conditions as  described below:

      •     Check "active" for those sites that currently have both active and inactive
            treatment, storage, or disposal units.

      •     Consider contaminated ground water plume sites "active."

8.     Years of Operation:  Enter the beginning and ending years of waste treatment,
      storage, and/or disposal  at the site.  If the site is  "active," enter the HRS date for the
      ending date.  Check "unknown" if the beginning or ending years of operation are not
      known.  For  consistency: if waste activities occurred during only  one year (e.g.,
      one-time event, accidental spill), the years of operation of the facility should be
                                    13

-------
      entered, and noted in the "Comments" section. If the site is a contaminated ground
      water plume,  use a default value of 0001  and 0001 for the beginning and ending
      years.

9.    Industry Responsible for Generating Material: Check all appropriate boxes that
      indicate industries responsible for generating the wastes that occur at the site. This
      refers to the  industry responsible for the waste,  not the original  product.  For
      example, if a hardware  store has drums of pesticides which  leak, the industry
      responsible is "retail" and not "manufacturing." It is important to try to  categorize the
      industry into one of the types listed for statistical analysis.  If these  listed industry
      types aren't applicable, check "other."  Further information may be provided under
      the "Comments" section.

      For consistency among respondents, please  note the following guidelines:

      •     If the site is a military facility, only "military" should be checked.

      •     Only check the "unknown" category if little or no information is available on
            the responsible industry or industries.

      •     "Food and kindred products" refers to food packaging/processing industries
            (e.g., canneries, bottlers) and the manufacturing of home goods such as
            toothpaste, shampoo, and cosmetics.

      •     "Chemicals and allied products" also includes paint manufacturing.

      •     Mark "electroplating" for any type of metal coating or metal finishing industry,
            unless  the  industry employs another type of coating as  the predominant
            activity (e.g., paint, plastic).

      •     For the majority of cases, the "other" category should be used if a specific
            general or subcategory of another type is not obvious. Examples of "other"
            categories include:

            —    combination industrial/        —    correctional facility
                 municipal landfill              —    distributor (gas, oil)
            —    industrial landfill              —    salvage yard
            —    waste storage/transfer        —    aircraft-related
                 facility                             service
            —    POTW                      —    radium processing

10.   Site  Activities/Waste Deposition: Check all appropriate boxes to indicate what
      types of treatment, storage, or disposal operations occur/occurred at the site.  If the
      available categories are  not sufficient to characterize the activities occurring at the
      site,  check "other" and supply a description. For consistency among respondents,
      please note the following guidelines:

      •     "Surface impoundments" should be restricted to primarily liquid containment.

      •     "Waste piles" may be covered or uncovered.
                                     14

-------
      •     "Industrial dump" refers to an illegal waste pile of industrial trash, chemicals,
           debris, etc.

      •     "Illegal dumping" ("out the back door") indicates situations where wastes are
           intentionally disposed  of in  undesignated disposal areas (e.g.,  dumping
           liquids and sludges onto the ground).

      •     "Episodic open dump" is a site at which third parties illegally dump wastes,
           often times without the  knowledge or approval of the site owner/operator.
           Note that "episodic open dump" may be an appropriate category even for a
           permitted facility if, for example, area residents or industries dispose of wastes
           at the site without  authorization.

      •     'Tanks — above ground" should be checked when  the type of tank  is not
           indicated, unless the site is a gasoline retail station.

      •     "Other sludge activity" refers to any sludge disposal action which cannot
           adequately be described by the other categories.

      •     "Discharge to sewer" should be checked when wastes have been intentionally
           discharged to either a sewer or a surface water body.  This category does not
           refer to wastes entering sewers or surface water as a  result of secondary run-
           off.  Permitted discharges should be noted in this category as well as in the
           "Regulatory Activities" section.

      •     "Airborne release" should be checked when incinerators, boilers, fire or burn
           pits, excessive dust, etc., are present at the site.

      •     "Drum/container storage" refers to intentional storage in specific areas.

      •     "Spills" are accidental in nature, mostly one time only occurrences. Leaking
           drums do not qualify as spills.

      Once again, try to categorize the activities or check "other" and give a description.
      Examples of legitimate "others" include:

      •     pesticide applications               •     wash pads
      •     septic tanks and leach fields         •     sumps
      •     dust suppression                   •     dry wells

11.    How Identified: Check  the appropriate  box to indicate how the site was initially
      identified to the EPA Superfund Program.  "Incidental" should be checked if the site
      was identified as a result of fortuitously driving by it, or by investigating another site.
      Anonymous complaints are categorized  as "citizen complaints."  "Other Federal
      program" should be marked for site identification through  programs such as the
      DOD Installation Restoration  Program.  Examples of  possible "other" categories
      include Congressional inquiry (e.g., Eckhardt list) and  ERRIS listing.

12.    Material Deposited By:  Indicate the  entity responsible for the  actual waste
      deposition. For example, "present owner" would be checked if a private individual
                                    15

-------
     authorized the dumping of chemical wastes on his property.  However, "third party"
     would be checked in the same scenario if the property owner had not authorized the
     dumping.  Again, for this category, "owner" refers to owner and/or operator.  For
     consistency, check "third party" for all contaminated ground water plume sites.

13.   Date Discovered: Enter two digits for the month, day, and year that the site  was
     identified to the EPA Superfund Program.  For example, June 27, 1982, would be
     entered as 06/27/82. In the event that the day or month is unknown, use 01 as the
     default value for each.  If the date cannot be determined, check "unknown."

14.   Material Source: Indicate whether the waste material was generated on site and/or
     off site, as appropriate.  Recyclers are  considered "on-site  generators."   For
     consistency, check "off-site generator" for contaminated ground water plume sites.

15.   Waste Easily  Accessible: Indicate whether or not the waste is easily accessible
     to the general  public. On-site workers should not be considered for this data field.
     Items to be considered in judging  accessibility include.complete cover over the
     waste area or a secure fence around the site. For example, waste material exposed
     at the surface  in a park or playground is easily accessible, while waste exposed at
     the  surface of a site  surrounded by a  locked chain-link  fence  is  not easily
     accessible. For consistency, the waste should be considered not easily accessible
     for contaminated ground water plume sites.

16.   First Proposed: Check the appropriate box identifying in which update the site was
     first  proposed in the Federal Register (this is usually listed under site name on the
     NPL folder).

17.   NPL Status:  Check the NPL status  of the site as of proposed Update #9,  July
     1989.  The NPL status of sites to be proposed for Update #10 should  be  marked
     as proposed.

18.   CERCLIS Number: Enter the 12-digit CERCLIS number (usually on  the SI  form or
     CERCLIS  printout).

19.   MRS Score:  Enter the MRS site score (Sm) from the MRS scoring package. If the
     scoring has been amended, use the most recent score.  In the "Comments" section,
     indicate the score for each of the migration pathways.

20.   Miscellaneous  Descriptive  Information:    Identify,  as appropriate,  multiple
     ownership or emergency action conditions. Examples of "other emergency action"
     include:

      • well closing                     • fences
      • distribution of bottled water        • consent decrees

     Additionally, the presence of lead (Pb) at a site should be noted in the appropriate
     data field.
                                    16

-------
Section 3 - Waste Description

      For data fields #1-3, wastes have been divided into three major groupings based on the
physical state of the waste: solid, liquid, and sludge. The physical state of the waste refers to
the waste as deposited and is usually identified as such in the MRS package or in the PA or SI.
For example, slurries are identified as either liquid or sludge, rarely as solid.  The presence of
each of these waste states at the site needs to be determined, along with the quantities involved.
Each  waste state grouping has been further divided into the type of waste deposited.  The
procedure for completing this  section, which should be followed for each waste state, is as
follows:

      1-3   Solids, Liquids,  Sludges:   First  determine if the particular waste state being
            evaluated ("solid" will be used here as an example) is/was present at the site. If
            solid wastes are/were not present, check "none."  If solids are/were present, then
            mark the appropriate waste type.  If the subcategories listed are not sufficient to
            characterize the particular waste  stream,  check  "other."  As with the previous
            sections, the evaluator should use the categories presented if possible, or check
            "other" and provide a brief description.  Some  examples of "other" waste streams
            include:

            • spent fuel                        •  biological waste (animal carcasses)
            • drilling muds (sludge)             •  batteries
            • dust                             •  construction debris
            • agricultural waste

            Finally, total the quantities of all waste streams and fill in the amount in the space
            provided.  Remember to mark the appropriate units.

            NOTE:     Identify the specific  contaminants found at the site in the upper right
                       hand  corner of the "Comments" section.

Section 4 - Environmental/Demographic Information

      1.     Demographics:

            a.    Distance to Nearest Population:  If known, provide the distance from the site
                  boundary to the nearest population.  Also, indicate the unit of measure that
                  was used. Population includes those persons occupying houses, apartment
                  buildings, schools, and businesses.  Use maps, if available, to provide best
                  estimates. If there is an on-site resident population, use 10 feet as a default
                  value.

            b.    Population Within 1 Mile?:  If there is a population within 1 mile of the site,
                  check "yes"  and enter the number of people within this radius.  When  the
                  number of individual residences is known, the convention is to multiply by 3.8
                  individuals/residence and use the product value as a reasonable population
                  estimate. If  a reasonable population estimate cannot be determined, check
                  "yes" and leave the number field blank.  A map may be used to determine
                  population.  If no appropriate information is in the file, check "unknown."
                                          17

-------
      c.    Population Within 3  Miles?:  Follow the same procedures as described
           above.   Again,  a map may be  useful.   If data are available regarding
           population within 4 miles of the site, indicate this and use the information. If
           this information is not in the file, mark "unknown."  By definition, if there is
           population within 1 mile of the site, there is also population within 3 miles of
           the site.

2.     Actual Environmental Damage Reported, Potential Population Affected: Indicate
      whether actual environmental damage has been reported at this site. Note that this
      does not include potential damage, only documented cases of actual impacts. For
      example, if the PA report states that leachate was observed entering an adjacent
      stream  or wetland, this can be considered an actual surface water impact, even if
      sampling results are not available. If "yes," indicate the type of damage that was
      reported and estimate the population that could potentially be affected.  If the
      potential population is  not known, write "unknown" in the space provided.  Please
      note that, by definition,  if an "HRS-observed release" has been  scored for a given
      pathway, then an environmental impact has been reported for that pathway.

      NOTE:      The number for potential population is often provided on the PA or SI
                 form.

3.     Observed Releases:  Indicate whether an observed release  of contaminants has
      been documented.  This information is available in the MRS scoring package.

4.     Water Supply Information for a 3-Mile Radius:

      a.    Local  Drinking  Water  Supply Source:  Identify whether  drinking water
           supplies are drawn from surface water and/or ground water within 3 miles of
           the site.   If, for example, the local area has a reservoir but some houses
           within 3 miles still use wells, then check "surface and  ground water."  If  all
           drinking water sources are outside of the 3-mile radius,  this should be noted
           as "none."

      b.    Total Population Served:  If available, provide the number of people served
           by the water supply system indicated in #4a.   Note that this population
           should reflect the population served by a source within 3 miles of the site; it
           may be more or less than the total population within 3 miles.  For example,
           if a well located two miles from the site is used to serve the population of a
           city of 60,000, the entire population of the city should be included even if the
           city  itself is outside of the 3-mile  radius.   If there is  no  drinking water
           population (all sources are outside 3-mile radius), use a default value of 01.

      c.    Drinking  Water Supply System Type:  Indicate the type of water supply
           system for the sources identified under #4a. "Municipal" should be indicated
           for any central water supply system, even if it is operated by a private water
           company, utility,  or individual  (e.g.,  trailer park  serviced by one privately
           owned well).
                                    18

-------
      d.    Ground Water Data:

           Other  Local Ground  Water  Uses:   Check all  appropriate boxes for
           predominant  uses  of  ground water  other  than drinking  water supply.
           Monitoring wells should not be considered. Some examples of "other" uses
           include commercial and dust control.

           Wells Within 1  Mile?:  If there are operable wells within  1 mile of the site,
           check  "yes" and indicate the total number of wells used for any  purpose,
           excluding monitoring wells.

           Wells Within  3 Miles?: If there are operable wells within 3 miles of the site,
           check  "yes" and indicate the total number of wells used for any  purpose,
           excluding monitoring wells.

           Distance to Nearest Well:  Provide the distance  from the site  boundary to
           the nearest operable well, excluding monitoring wells.  Indicate what unit of
           measure was used.  If  the well is located on site, use  10 feet  as  a default
           value.  Note that by MRS definitions, the site  boundary can be  extended to
           the farthest point of documented  contamination attributable to the  site.

           Depth to the  Uppermost Used Aquifer: Provide the depth from the ground
           surface to the uppermost aquifer that is or may be used.  If the uppermost
           aquifer- is no  longer used because of contamination attributable to the site,
           the depth to  this aquifer should be entered.  Always  indicate the unit of
           measure used.  If a range of depth is given, use the midpoint value for the
           data field. Use a default value of 1 foot if waste was directly deposited below
           the water level of the uppermost used aquifer.

           NOTE:     "Depth to the Uppermost Used Aquifer" is often provided  in the
                      MRS scoring package.

      e.    Surface Water Data:

           Other  Local Surface Water Uses: Mark  all appropriate  boxes for uses of
           surface water, other than drinking water supply, within 3 miles.

           Surface Water Adjacent to/Draining Site: Identify all types of surface water
           adjacent to or draining the site that could potentially be affected by overland
           runoff  from the site.  Use professional judgment and MRS definitions as
           necessary.

           Distance to  Nearest Downstream Intake:   Provide the distance to the
           nearest downstream intake in feet or miles, if known.

5.     Ecological Information:

      Is Site In Or Near Sensitive Environment?:  Sensitive environments are defined as
      estuaries, 100 year floodplains, critical habitats  (Federally designated only) and
      some coastal areas. If the site is in or near one of these environments, indicate the
                                    19

-------
      6.
type of sensitive environment and whether the site is "in" or "near" the environment.
"Near" is considered to be within a 3-mile radius.

Pathways of Concern:  Check all pathways that received a score greater than zero
in the MRS scoring package.  When reviewing the MRS scoring package, please
note the actual score for each pathway in the "Comments" section.
Section 5 - Regulatory and Response History

      1.    Regulatory Activities Prior to Preliminary Assessment:  Indicate any regulatory
           activities that occurred at the site prior to the PA. Examples of these activities could
           include RCRA notification or inspections, NPDES permits and/or exceedences, State
           health department inspections  of landfills and/or DOD  Installation  Restoration
           Program activities ("other Federal program" category).

      2.    RCRA Status:  Indicate the appropriate RCRA category.  If the site is not a RCRA
           site, check "not applicable." Ground water contamination plume sites are to be
           included in the "not applicable" category.

Section 6 - Comments

      This section is not an optional segment of the data collection form.  It must be completed,
at a minimum, with a brief narrative description of site conditions, including any discussion or
clarification of the information presented elsewhere on the form.  In addition, each form must be
quality control checked for completeness, and initialed by another evaluator in the lower right
corner of page 4. The "Comments" section is a crucial component of the data collection form;
verbosity is encouraged.
