Foreword
The U.S. Environmental Protection Agency (US EPA) is charged by Congress with protecting
the Nation's land, air, and water resources. Under a mandate of national environmental laws, the
Agency strives to formulate and implement actions leading to a compatible balance between
human activities and the ability of natural systems to support and nurture life. To meet this
mandate, US EPA's research program is providing data and technical support for solving
environmental problems today and building a science knowledge base necessary to manage our
ecological resources wisely, understand how pollutants affect our health, and prevent or reduce
environmental risks in the future.
The Center for Environmental Solutions and Emergency Response (CESER) within the Office of
Research and Development (ORD) conducts applied, stakeholder-driven research and provides
responsive technical support to help solve the Nation's environmental challenges. The Center's
research focuses on innovative approaches to address environmental challenges associated with
the built environment. We develop technologies and decision-support tools to help safeguard
public water systems and groundwater, guide sustainable materials management, remediate sites
from traditional contamination sources and emerging environmental stressors, and address
potential threats from terrorism and natural disasters. CESER collaborates with both public and
private sector partners to foster technologies that improve the effectiveness and reduce the cost
of compliance, while anticipating emerging problems. We provide technical support to EPA
regions and programs, states, tribal nations, and federal partners, and serve as the interagency
liaison for EPA in homeland security research and technology. The Center is a leader in
providing scientific solutions to protect human health and the environment.

1. Background
UST Finder is an online mapping tool providing access to localized information on the attributes
and locations of leaking underground storage tanks (LUSTs), underground storage tank (UST)
facilities, and underground storage tanks. UST Finder integrates static, state sourced data as of
2018-2019. This state sourced data was curated and standardized to create a national profile of
the 2018-2019 UST universe by EPA's Office of Underground Storage Tanks, Office of
Research and Development, and the Association of State and Territorial Solid Waste
Management Officials.
UST Finder and associated data are publicly available and free to use. Located on EPA's
GeoPlatform, it incorporates UST data into a user-friendly GIS environment where stakeholders,
decision-makers, and emergency responders can easily access UST information on a computer,
tablet or smartphone.

3.3.1. Facility and LUST ID
Some attributes are state sourced, and others are EPA generated. In most instances the Facility
ID and LUST ID (the numbers after the state abbreviation) are the state issued IDs. These IDs
reference individual state databases—where potentially more information about LUST sites can
be found.
3.3.2. Locational Information
If coordinates (Latitude and Longitude) were provided by the state, they were used to map the
LUST site. If no coordinates were provided, EPA geocoded the state sourced Address. The
Coordinate Source field identifies whether the coordinates were state sourced or geocoded. If
geocoded, the Address Match Type identifies how the address was matched (i.e. by postal zip
code, point address, street name, etc.).
The amount of time permitted before providing notification as well
as the reportable quantity threshold vary by implementing agency.
The reportable quantity of releases is not available in UST finder
nor the source, type, or extent of release.
9
-------
3.3.3. Reported Date
The Reported Date field is either the date the release was
discovered or reported to the state. Note that these dates are
not available for all states and releases.
The year in which states started
collecting LUST data—and thus
available in UST Finder—varies
by state. In general, most
states started cataloging
releases by 1989.
3.3.4. Release Status
There are three release Status types: Open, No Further Action, and Unknown. It should be noted
that individual states set their own criteria for what defines an open or closed release. An open
release generally means the LUST site has not been remediated and is undergoing assessment,
treatment and/or monitoring. For Kentucky, all the releases statuses are unknown.
3.3.5. Substance Released
The Substance field contains the substance associated at the UST release site. A site can have
one or many substances released. The substance naming convention is not standardized between
states. Table 3.1 lists the 17 states with substance release information.

The remaining descriptions or UST Release attributes are EPA generated.
3.3.6. Estimated Population
The Estimated Population within 1500 ft field provides an estimate of the number of people
living within 1,500 ft of a release. The 2010 Census blocks were used for the population data.
1,500-foot buffers were generated for each release and populations were estimated by the percent
buffer intersection to each overlapping census block. These calculations were only performed for
releases with coordinates provided by states or geocoded address match types of 'StreetAddress',
'Streetlnt', 'Subaddress', or 'PointAddress'.
3.3.7. Estimated Private Domestic Wells
The Estimated Private Domestic Wells within 1500 ft field provides estimates of the housing
units using private domestic wells as their primary source of water. These well estimates were
developed by the EPA. The data provide improved estimates of the dependence and spatial
distribution of housing units reliant on private domestic by census block. In order to capture the
potential vulnerability of private drinking water wells to leaking underground storage tanks, UST
Finder calculated 1,500 ft buffers for each release and tabulated the intersection of wells at the
census block level.
3.3.8. Land Use
The Land Use type around release sites is calculated using data from the National Land Cover
Database (NLCD). Knowing the land use type near release sites can suggest whether a site is in
an urban or rural area, for example. Assigning development types (either developed-low,
medium or high intensity) to releases sites can suggest the number of people, building, and level
of development nearby. This can help inform, for example, remediation strategies. In-situ
bioventing or biosparging may not be an appropriate remediation strategy in high intensity
developed area due to the risk of vapor intrusion to nearby buildings. Land Use was calculated
by assigning the majority land use type to a 300 ft buffer around release sites. If the majority
land use type was not a "developed" land use type, "non-developed" was assigned.
3.3.9. Wellhead and Surface Water Source Water Protection Areas
The UST Release layer also provides information on whether a release site is Within a Source
Water Protection Area (SPA) or Within a Groundwater Wellhead Protection Area (WHPA).
This information is generated by U.S. Environmental Protection Agency Office of Water and
provides source water protection areas for surface water source facilities as well as wellhead
protection areas for groundwater sources. The sources for this GIS analysis are the Safe Drinking
Water Information System (SDWIS) Federal Data Warehouse and the National Hydrography
Dataset Version 2.1 (NHDPlus) (https://www.epa.gov/waterdata/nhdplus-national-data).
The EPA Source Water Protection Area (SPA) dataset provides spatially referenced source water
protection areas for public drinking water system (PWS) source facilities located in the United
States. Source facility location data were obtained from the Safe Drinking Water Information
11
-------
System/Federal Version (SDWIS/Fed) and include active surface water facilities (e.g., intakes,
reservoirs, infiltration galleries, and springs) with a Water Type description of 'surface water'
(SW) or 'ground water under the influence of surface water' (GU). Ground water facilities (e.g.,
wells) with valid locations (lat/long coordinates) and a Water Type description of ground water
are also included as Wellhead Protection Areas (WHPAs). Surface water (SPA) delineations in
the CONUS, Hawaii, U.S. Virgin Islands, and Puerto Rico are composed of National
Hydrography Dataset Plus version 2.1 catchments located 24-hour time of travel upstream of all
valid surface water source facility locations, while ground water protection areas (WHPAs) are
composed of NHDPlus V 2.1 catchments that intersect wells. SPA and WHPA delineations in
Alaska represent a 1-mile buffer radius due to limited availability of NHDPlus catchments in
Alaska.
While these protection areas and locations of public drinking water intakes are not public
information, UST Finder obscures the exact boundaries/locations by providing binary operators
to identify whether or not a release is within a source water protection or ground water protection
area, with either a "Yes" or "No". By identifying areas significant to drinking water source
protection while obscuring the exact locations of intake facilities, this dataset gives a wide range
of planners, policy makers, and practitioners the information needed to target and prioritize areas
for protection in proximity to UST releases.
The WHPA and SPA Public Water System and Facility ID is the concatenated PWSID and
FAdLITYID which uniquely identifies a water system facility in one field.
3.3.10. 100-year Floodplain
The Within 100-year Floodplain field provides information on whether a UST release is within
an estimated flood inundation area. The data used for identifying these zones is a flood
inundation model that estimates FEMA's Flood Insurance Rate Maps (FIRMs) for the
conterminous United States. Because of the high cost of FEMA flood modeling, only 60% of the
conterminous United States have 100-year floodplains mapped. To fill in these "gaps" the US
EPA developed this product to support research and online mapping activities related to the
EnviroAtlas. The model hit rate for the CONUS was 0.79 compared to the FIRM, indicating that
the model captured 79% of the 100-year floodplain identified by FEMA. Releases are identified
to be within the estimated 100-year floodplain by either a "Yes" or "No". For more information
on this product or to download, visit the service here.

3.4. UST Facilities Layer
The UST Facilities
layer provides
information on
facilities that
currently have (as
of 2018-2019) at
least one open or
temporarily out of
service (TOS) UST
(shown in blue in
Figure 5) as well as
historical
facilities—facilities
that have no active
or TOS USTs
(shown in light
blue in Figure 5).
In addition to the locations of releases, each release has associated data. Associated data can be
viewed in pop-ups or the feature's attribute table.
3.4.1. Facility ID
Some attributes are state sourced, and others are EPA generated. In most instances the Facility
ID (the numbers after the state abbreviation) are state issued IDs. These IDs reference individual
state database—where potentially more information about facilities can be found.
3.4.2. Locational Information
If coordinates (Latitude and Longitude) were provided by the state, they were used to map the
facility. If no coordinates were provided, the EPA geocoded the state sourced Address. The
Coordinate Source field identifies whether the coordinates were state sourced or geocoded. If
geocoded, the Address Match Type identifies how the address was matched (i.e. by postal zip
code, point address, street name, etc.).
3.4.3. Tank Counts
The Open USTs. Closed USTs. and Temporarily out of Service USTs fields list the number of
individual tanks, by status, at the facilities location as of 2018-2019. For most states, these
counts were calculated from the Underground Storage Tank table.
Figure 5. UST Facilities
13
-------
3.4.4. Facility Status
The Facility Status field identifies whether a facility currently has one or more open or TOS
tanks, or whether it is a legacy facility—one with only closed tanks.
The following attributes are similar to the UST Releases dataset. See the linked releases
descriptions for more information
3.4.5. Estimated Population
See the Estimated Population within 1500 ft description here.
3.4.6. Estimated Private Domestic Wells
See the Estimated Private Domestic Wells within 1500 ft description here.
3.4.7. Land Use
See the Land Use description here.
3.4.8. Wellhead and Surface Water Source Water Protection Areas
See the Wellhead and Surface Water Source Water Protection Area description here.
3.4.9.100-year Flood plain
See the estimated 100-vear Floodplain description here.
3.4.10. Tank Capacities in Pop-up
For most facilities, within the pop-up window, there
is a bar chart of tank capacities for each tank at a
given facility. This chart provides the capacity for
every open, closed, and TOS tank at a facility.
Hover over a bar to see the tank number associated
with the tank capacity.
Figure 6. Tank Capacity Bar Chart
-------
3.5. UST Table
The UST table is non-spatial data containing information on
USTs for 49 states and Washington D.C. (excluding Idaho).
UST information is contained in a stand-alone table. This table
is related to each facility in a 1-many relationship, meaning for
most facility, one or many tanks are linked by a common
Facility ID. UST attributes can be found in the USTs attribute
table or through the facilities pop-up window, discussed later.
3.5.1. Tank ID
The UST Tank ID is the unique tank ID number. Typically, the
Tank ID is the concatenated Facility ID and tank number.
Q Facilities
l~l Releases
~
Q Fi
3.5.2. Installation Date Figure 7. USTs Layer in the
The UST Installation Date is the date the UST was installed, if Layer List menu
provided by the corresponding state agency.
3.5.3. Removal Date
If the UST was removed from the ground, a Removal Date is given, if this information was
provided by the corresponding state agency.
3.5.4. Capacity
In gallons, the Capacity of the tank. If the tank contained compartments, the compartment
capacity was summed together to get a total tank capacity.
For California, individual tank compartments are treated as an individual tank. You can discern
whether a California entry is a non-compartmentalized tank or compartment by the Tank ID.
They CA Tank ID syntax is "CA"&[Facility ID]&"_"&"A Stand-alone Tank" or "One in a
Compartment Unit"&"_"&[number of compartments].
Note that some state use 99, 999, 9999, 99999, etc. as null placeholders for tank capacities. If a
tank's capacity is a series of nines, it should most likely be treated as "null".
3.5.5. Substance
If available in state databases, the Substance stored in the UST is listed. Every state has a
different substance classification system. For example, one state may use the term "gasoline" to
encompass different ethanol blends, premium and standard, leaded (historic) and unleaded, etc.;
while another state list the unique types of gasoline (i.e. El 5). Given the disparity in defining
substance types between states, one should be careful comparing the substances stored from state
to state.
15
-------
Not all USTs are federally regulated. Tanks containing home heating oil consumed on site, for
example, is not a federally regulated tank. The goal of UST Finder was to catalog federally
regulated tanks (for more information on UST laws and regulations visit here). When possible,
non-regulated tanks were not included. If for example a state classified a tank as non-federally
regulated, that tank was not included; or if a tank was identified to contain home heating oil and
was consumed on site, that tank was not included. However, there are states and instances where
the regulated, non-regulated distinction could not be made, and non-federally regulated tanks
may have been included in UST Finder.
Some Substance entries contain more than one substance. For the most part, this is due to either
listing the substances in multiple individual compartments or listing the substances previously
stored in the tanks.
3.5.6. Tank Wall Type
The Tank Wall Type identifies whether the tank is "Single" walled or "Double" walled.
3.6. Viewing UST Attributes
Mentioned previously, the UST table is related to the facilities table. This section will discuss
several ways to view UST attributes associated with an UST Facility.
3.6.1. Viewing USTs information within the UST Facilities Pop-up
For every facility with related UST data, you can view the UST information via the UST
Facilities' pop-up.
Step 1: Click a UST Facility to enable the pop-up and scroll to the bottom of the pop-up and

of the attribute table, select the layer you want to view the attributes of—either Facilities,
Releases, or USTs. Note that the attribute table only shows the features within the current map
extent. The bottom left of the table shows the number of facilities or releases within the map
extent and in the attribute table. By default, the "Filter by map extent" I I button is
turned on. Deselecting this button returns all features (not just the ones within the map extent) to
the attribute table. You can select an individual release or facility by clicking to the left of a row.
When a row is selected you can Zoom to the site's location on the map.
The Options button allows the user to Export fields to CSV and filter the attribute table.

-------
5.1. Filter
Section 4.2 describes ways to filter UST data
via the attribute table. You can also filter data
using the Filter widget. The Filter widget is
divided into two section: Facilities (blue) and
Releases (red). The facilities section only filters
the facilities layer and the release section only
filters the release layer. The filter labels
indicate what is being filters, for example, the
State filter will only return facilities for a user
defined state. Figure 18 shows the facilities
filtered by State, in this case, Delaware. Note
that the Filter widget not only filters the
locations on the map, but also the attribute
table.
You can also create multiple, compounding filters. If more than one filter is used, note that all
statements in the argument are considered true. For example, in Figure 19, the filter returned
UST releases that are within a source water protection area (surface water) and were reported on
or after 1/1/2010.
You can create a custom filter
within the Filter widget by clicking
the black and white button at the
bottom right corner (filter and
pencil icon, seen in Figure 19). In
the custom filter window select the
layer you wish to perform the filter
on and click + Add express....
+ Add express... Figure 20 illustrates
a custom filter on the facilities
layer where only facilities that
contain the word School is shown
in the map (and attribute table).

status and then run the Near Me widget
5.3. Info Summary
The Info Summaiy widget quickly tabulates the number of facilities and/or releases within a map
frame. In Figure 22, the facilities and releases were previously filtered to sites within Rhode
Island. The Info Summary widget tells us how many facilities and releases are in Rhode Island
and their counts by status.
