About MyEnviroMapper
The MyEnviroMapper application provides an
interactive Geographic Information System (GIS) functionality using
Environmental Protection Agency (EPA) spatial data and external GIS web
services. MyEnviroMapper allows you to view spatial data
for any city or ZIP code. It will create a detailed map for your
window location which includes EPA regulated facilities, schools,
churches, hospitals, streams, impaired streams, and impaired water
bodies. You can manipulate and change the displayed map by zooming in,
zooming out, identifying features, re-centering the map, and
displaying a locator map. In addition, MyEnviroMapper
provides detailed reports of EPA regulated facilities through the
facilities displayed on the map or listed beneath it.
- Map Options - Options for viewing and displaying your map, include Zoom In/Out, Pan Map, Change Background, and a Locator Map.
- Tools - Click the Tools button to print the map, measure distances on the map or see images for the selected locations.

Facility Reports
MyEnviroMapper can generate or link to many different
reports throughout EPA's databases. Listed below are several examples of
how to generate the reports.
Facility Report
To view a facility report for any facility in the map window, first select a Map Layer (see Search Envirofacts).
When you mouse over the facility, it will provide the facility name
hyperlinked to the Envirofacts Multisystem report. From here, you can
find facility information, including toxic chemical releases, water
discharge permit compliance, hazardous waste handling processes,
Superfund status, and air emission estimates for this site, as
applicable.
What's Nearby
To view detailed demographic, environmental concerns, sites and
facilities, and places, use the What's Nearby option available from
the facility mouse-over. First select a radius for your report. The
default radius is 1 mile, but you can specify the radius around the
facility up to 5 miles.
Then click the What's Nearby button ().
The resulting report shows:
- Places - The box next to the layer name can be checked to add
these layers to the map. Numbers can be clicked to see a list of the
facilities.
- # of Schools - Buildings or group of buildings used as an
institution for study, teaching, and learning (e.g., academy, college,
high school, university).
- # of Hospitals - Buildings where the sick or injured may receive medical or surgical attention (e.g., infirmary, clinic).
- # of Churches - Building used for religious worship (e.g., chapel, mosque, synagogue, tabernacle, temple).
- Sites and Facilities - The box next to the layer name can be
checked to add these layers to the map. Numbers can be clicked to see a
list of the facilities.
- # of Air 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.
- # of Superfund Sites(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.
- # of Toxic Releases (TRI Sites)
- 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.
- # of 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.
- # of Water Dischargers (PCS/ICIS) - 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) and
Integrated Compliance Information System (ICIS), 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 discharged.
- # of Brownfields (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.
- # of 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
includes facility information for facilities regulated by these Code of
Federal Regulation (CFR) parts: 40 CFR Parts 191 and 194; 40 CFR Part
61; and 40 CFR Part 300.
- # of TSCA
- TSCA addresses the production, importation, use, and disposal of
specific chemicals including polychlorinated biphenyls (PCBs), asbestos,
radon and lead-based paint.
