Print Page | Close Window
As you zoom in or out, some features, particularly demographics, become unavailable because they depend on the scale of the current map window. For example, when you zoom in on a single intersection, Population Density by State becomes unavailable. Likewise, when you zoom out to see the whole United States, Population Density by block, blockgroup, and census tract all become unavailable. When this happens, the option under "Select Map Contents" will be disabled and the feature will not be displayed on the map, even if it was selected before you zoomed in or out.
- Also, as you zoom out, facilities that are close together become
clustered. When you mouse over them, you will see a list of sites in the bunch
and as you zoom in, the sites will begin to separate.
- The order in which the layers are shown on the map will depend on the
order in which they are added. Turn layers on/off to change the order in which
they display on the map. If you zoom in or out, the order shown may change
depending on the order in which the data is retrieved.

Reporting to the EPA:
- Hazardous Waste
(RCRAInfo) - Hazardous waste is
waste that is dangerous or potentially harmful to our health or the
environment. Hazardous wastes can be liquids, solids, gases, or sludges. They
can be discarded commercial products, like cleaning fluids or pesticides, or
the by-products of manufacturing processes.
Emissions (AFS) - The Air
Facility System (AFS) contains compliance and permit data for stationary
sources regulated by EPA, state, and local air pollution agencies. States use
AFS information to prepare State Implementation Plans (SIP) and track the
compliance status of point sources with various regulatory programs under the
Clean Air Act.
Dischargers (PCS) - As
authorized by the Clean Water Act,
the National Pollutant Discharge Elimination System (NPDES) permit program
controls water pollution by regulating sources, such as municipal and
industrial wastewater treatment facilities, that discharge pollutants into
waters of the United States. EPA tracks water discharge permits through the
Permit Compliance System (PCS), which includes information on when a permit
was issued and when it expires, how much the company is permitted to
discharge, and the actual monitoring data showing what the company has
- Toxic Releases
(TRI) - The Toxics
Release Inventory (TRI) is a publicly available EPA database that contains
information on toxic chemical releases and waste management activities
reported annually by certain industries as well as federal facilities. The
database also contains links to compliance and enforcement information.
- Superfund (CERCLIS)
- Superfund is the
Federal Government's program to clean up the nation's uncontrolled hazardous
waste sites. The National
Priorities List (NPL) is the list of national priorities among the known
or threatened releases of hazardous substances, pollutants, or contaminants
throughout the United States and its territories.
(ACRES) - The Assessment,
Cleanup, and Redevelopment Exchange System (ACRES) captures grantee reported
data on environmental activities and accomplishments (assessment, cleanup and
redevelopment), funding, job training, and details on cooperative partners and
leveraging efforts - a central objective of the Brownfields Program. The
information in ACRES is provided at the property and grant level.
RADInfo - The Radiation Information Database (RADInfo)
contains information about facilities that are regulated by U.S. Environmental Protection Agency (EPA)
regulations for radiation and radioactivity. RADInfo uses EPA's current "Standard Data Elements
For Facility Identification" approved on November 21, 2000. This State/EPA standard offers a common and
consistent way to identify facilities of interest to the EPA.
Toxic Substances Control Act (TSCA)
- The Toxic Substances Control Act of 1976
provides EPA with authority to require reporting, record-keeping and testing requirements, and restrictions relating to
chemical substances and/or mixtures. Certain substances are generally excluded from TSCA, including, among others,
food, drugs, cosmetics and pesticides. TSCA addresses the production, importation, use, and disposal of specific
chemicals including polychlorinated biphenyls (PCBs), asbestos, radon and lead-based paint.
Water Monitoring Stations:
- USGS Water Monitors
(NWIS) - The United States Geological Survey (USGS) water monitors layer is retrieved in real-time from the USGS National Water Information System (NWIS) website. The NWIS service provides current conditions from selected surface water, ground water, and water quality sites.
- EPA Water Monitors (STORET)
quality monitoring information comes from EPA's Storage and Retrieval (STORET)
System, a repository of physical, chemical, and biological monitoring data
from State and Federal agencies, watershed organizations, volunteer groups,
and others. Surface water, Ground water, and Others are general categories for
more specific STORET Station Types.

Polygons () - Airport
Polygons represent airport boundaries and airport runways within the United
States. All airports have a boundary and most have at least one runway.
Points () - The Airport
points layer is public use airports extracted from The Public Use Airports
database of the National Transportation Atlas Databases-2001(NTAD-2001),
published by the Department of
Transportation, Bureau of Transportation Statistics.

lines and rights of way, there may be differences in location and coverage
between this layer and the railroads depicted in the Virtual Earth basemap
In United States environmental law, a nonattainment area is an area
considered to have air quality worse than the National Ambient Air Quality
Standards as defined in the Clean Air
Act. Nonattainment areas must have and implement a plan to meet the
standard. An area may be a nonattainment area for one pollutant and an
attainment area for others. NEPAssist includes nonattainment areas for Ozone
8-hour, Lead (Pb), Particulate Matter (PM2.5) 24-hour, and PM2.5 8-hour.
Top of page
8-hour (1997 standard)() - Ozone (O3) is a gas
composed of three oxygen atoms. Ground-level or "bad" ozone is not emitted
directly into the air, but is created by chemical reactions between oxides of
nitrogen (NOx) and volatile organic compounds (VOC) in the presence of
sunlight. Emissions from industrial facilities and electric utilities, motor
vehicle exhaust, gasoline vapors, and chemical solvents are some of the major
sources of NOx and VOC.
(2008 standard)() - Lead (Pb) is a metal found
naturally in the environment as well as in manufactured products. The major
sources of lead emissions have historically been from fuels in on-road motor
vehicles (such as cars and trucks) and industrial sources. As a result of
EPA's regulatory efforts to remove lead from on-road motor vehicle gasoline,
emissions of lead from the transportation sector dramatically declined by 95
percent between 1980 and 1999, and levels of lead in the air decreased by 94
percent between 1980 and 1999. Today, the highest levels of lead in air are
usually found near lead smelters. The major sources of lead emissions to the
air today are ore and metals processing and piston-engine aircraft operating
on leaded aviation gasoline.
Annual (1997 standard)() -"Particulate
matter," also known as particle pollution or PM, is a complex mixture of
extremely small particles and liquid droplets. Particle pollution is made up
of a number of components, including acids (such as nitrates and sulfates),
organic chemicals, metals, and soil or dust particles. "Fine particles," such
as those found in smoke and haze, are 2.5 micrometers in diameter and smaller.
These particles, known as PM 2.5, can be directly emitted from sources such as
forest fires, or they can form when gases emitted from power plants,
industries and automobiles react in the air. These areas exceed the 1997
annual design value for PM 2.5.
24-hour (2006 standard)()
-"Particulate matter," also known as particle pollution or PM, is a complex
mixture of extremely small particles and liquid droplets. Particle pollution
is made up of a number of components, including acids (such as nitrates and
sulfates), organic chemicals, metals, and soil or dust particles. "Fine
particles," such as those found in smoke and haze, are 2.5 micrometers in
diameter and smaller. These particles, known as PM 2.5, can be directly emitted
from sources such as forest fires, or they can form when gases emitted from
power plants, industries and automobiles react in the air. These areas exceed
the 2006 24-hour design value for PM 2.5.

Streams () - Streams that have excess
pollutants and are not clean enough to support recreational uses.
Water Bodies () - Water Bodies that
have excess pollutants and are not clean enough to support recreational uses.
Source Aquifers () - A sole or principal
source aquifer as an aquifer that supplies at least 50 percent of the drinking
water consumed in the area overlying the aquifer. These areas may have no
alternative drinking water source(s) that could physically, legally and
economically supply all those who depend on the aquifer for drinking water.
For convenience, all designated sole or principal source aquifers are referred
to as "sole source aquifers"(SSAs).
Streams are linear surface water features. The streams layer is based on the
National Hydrography Dataset (NHD)
1:100,000 scale streams network.
Bodies () - Water bodies are area
surface features such as ponds, lakes and wide rivers. The water bodies layer
is from U.S. Census Bureau

Land Cover 2006
Land cover is the physical material at the surface of the earth. Land covers
include grass, asphalt, trees, bare ground, water, etc. Land cover is distinct
from land use despite the two terms often being used interchangeably. Land use
is a description of how people utilize the land and socioeconomic activity -
urban and agricultural land uses are two of the most commonly recognized
high-level classes of use. The land cover color scheme may seem slightly
different in the map versus in the legend because the map feature has been made
transparent for easier viewing when overlaying with other data sets.

Wetlands Inventory Wetlands
The U.S. Fish and Wildlife Service (Service) is the principal Federal agency
that provides information to the public on the extent and status of the Nation's
wetlands. The Service's strategic plan for our vast national wetland data
holdings is focused on the development, updating, and dissemination of wetlands
data and information to Service resource managers and the public. The
development of the Wetlands Master Geodatabase is in direct response to the need
to integrate digital map data with other resource information to produce timely
and relevant management and decision support tools. Wetlands provide a multitude
of ecological, economic and social benefits. They provide habitat for fish,
wildlife and a variety of plants. Wetlands are nurseries for many saltwater and
freshwater fishes and shellfish of commercial and recreational importance.
Wetlands are also important landscape features because they hold and slowly
release flood water and snow melt, recharge groundwater, act as filters to
cleanse water of impurities, recycle nutrients, and provide recreation and
wildlife viewing opportunities for millions of people.Top of
Q3 Flood Hazards layer is portraying an older set of flood hazard data when
data for areas which flood hazard data are not available from the National Flood
Hazard Layer (NFHL).Flood
Flood hazard areas are defined as the area that will be inundated by the
flood event having a 1-percent chance of being equaled or exceeded in any given
year. The 1-percent annual chance flood is also referred to as the base flood or
100-year flood. Special Flood Hazard Areas(SFHAs) are labeled as Zone A, Zone
AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO,
Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30. Moderate flood
hazard areas, labeled Zone B or Zone X (shaded) are also shown on the FIRM, and
are the areas between the limits of the base flood and the
0.2-percent-annual-chance (or 500-year) flood. The areas of minimal flood
hazard, which are the areas outside the Flood Hazard area and higher than the
elevation of the 0.2-percent-annual-chance flood, are labeled Zone C or Zone X

Understanding the Data
The NEPAssist application draws and displays environmental data from many
locations and sources to easily provide access to this information in one place.
Each mapping layer and report question in the NEPAssist application is supported by metadata that
can be viewed in the data description window.
Metadata describes the contents and context of the data files, including the
source, the date the data was generated, accuracy, and projections. When
accessing information in NEPAssist, the data file and corresponding metadata
need to be referenced by the user. Do not reference the NEPAssist application
directly because data layers within NEPAssist are continually updated and
refreshed when more current data is available.
For example: If you have a hazardous waste site in your project area, cite the EPA Envirofacts database, and the last data retrieval date from the EPA source database, the Resource Conservation and Recovery Act Information (RCRAInfo) System.
