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  MRS 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 MRS  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 9 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 9 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 105 sites located in Region
9,  four 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 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 9.

•  Over a quarter of NPL sites in Region 9
   are located in rural areas; approximately
   16% are located in urban areas (Chart
   1).

•  Over  a third  of  Region  9 NPL  sites
   manage(d) wastes in industrial landfills;

Nearly half of Region 9 NPL sites are
owned  by private  industry;  about  a
quarter  are  owned  by  the  federal
government (Chart 7).

Approximately 70%  of NPL  sites in
Region 9 are active facilities (Chart 9).

Nearly one-half of NPL sites in Region 9
contain  wastes   generated  by
manufacturing industries (Chart 10).

Over 60% of  Region 9 NPL sites were
identified  through   state  and  local
programs  (Chart 17).

Over 80% of NPL sites in Region 9 have
released  hazardous   substances   to
ground water; over 20% have released
hazardous substances to surface water
(Chart 23).
    Nearly a quarter of Region 9 NPL sites
    have a sensitive environment  within 3
    miles (Chart 33).

    Over 90% of Region 9 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 105 sites reviewed in Region 9 — 101 that were on the NPL as of February 1991,
   and four 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 HRS 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 9  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 9 as  well as the other eight
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 9 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.

2.5   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!1 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

-------
           HRS 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 miies 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 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.

      6.    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.
