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 processsites 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.
