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 HRS
    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.
                                I ,

    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 8 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 8 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 ail
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 43 sites located in Region
8, none 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 HRS 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 HRS (with the
exception of four deleted sites  as noted
above).   Sites  listed on  the  basis of the
revised HRS were not evaluated.

    Data for the NPL characterization project
were collected in two stages. First, the final
HRS 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,  HRS  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 8.

•   Almost half of NPL sites in Region 8 are
    located in rural areas; 14% are located
    in urban areas (Chart 1).

•   Over a third  of  Region 8 NPL  sites
    manage(d) wastes in industrial landfills;
    over 60%  manage(d) wastes in surface
    impoundments (Chart 4).

Over 40% of Region 8 NPL sites are
owned by private industry; about 20%
are owned by the federal government
(Chart 7).

About 60% of NPL sites in Region 8 are
active facilities (Chart 9).

More than half of NPL sites in Region 8
contain   wastes   generated   by
manufacturing industries (Chart 10).

Over  45% of Region 8 NPL  sites were
identified   through   state  and  local
programs (Chart 17).

Nearly 80% of NPL sites in Region 8
have released hazardous substances to
ground  water; almost  two-thirds have
released  hazardous   substances   to
surface water (Chart 23).
    Nearly a third of Region 8 NPL sites
    have a sensitive environment within 3
    miles (Chart 33).

    Over 90% of Region 8 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 43 sites reviewed in Region 8.                            -

   Efforts were made to characterize site conditions/surroundings as they existed at the time of
   the MRS score. The MRS 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 8  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. A copy of
this form is  provided in 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 Region 8 as well as the  other eight
Regions.

2.2   SOURCE  OF  DATA

   Most  of the questions on the  data
collection form could be answered in the first
stage  of the data  collection .process  by
reviewing  HRS scoring packages at the
Headquarters  Superfund  Docket.   The
second stage involved filling in data gaps at
the Region 8 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 jevel  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.

2.5   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 mil 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 HRS
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.

-------
            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 HRS 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 HRS scoring
      package.

7.    Site Status:  Check the appropriate box to indicate the status of the site at the time
      of the HRS score. Sites are to be considered "active" if waste treatment, storage,
      or disposal activities are taking place at the time of the HRS 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

10.
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.

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/
                 municipal landfill
                 industrial landfill
                 waste storage/transfer
                 facility
                 POTW
                                              correctional facility
                                              'distributor (gas, oil)
                                              salvage yard
                                              aircraft-related
                                              service
                                              radium processing
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 |n 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 ptume 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 HRS 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
      • distribution of bottled water
• fences
* 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 HRS 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.

           Welts 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 HRS 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
                       HRS 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 HRS 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

-------
            type of sensitive environment and whether the site is "in" or "near" the environment.
            "Near" is considered to be within a 3-mile radius.
             i.
      6.     Pathways of Concern: Check all pathways that received a score greater than zero
            in'the HRS scoring package.  When reviewing the HRS 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.
