Databases and Tools
EPA makes available numerous databases and tools related to emergency management. These resources are designed to help first responders address emergency situations, assist facilities in complying with emergency management regulations, and give the public an improved understanding of chemicals in their community.
- ALOHA: Areal Locations of Hazardous Atmospheres
- CAMEO: Computer-Aided Management of Emergency Operations
- CAMEO Chemicals
- CERCLIS - Comprehensive Environmental Response, Compensation and Liability Information System
- CRW: Chemical Reactivity Worksheet
- MARPLOT: Mapping Applications for Response, Planning, and Local Operational Tasks
- National Response Center
- EPCRA/CERCLA/CAA §112(r) Consolidated List of Lists – October 2012 Version
- VZIS - Vulnerability Zone Indicator System
Part of the CAMEO suite, ALOHA® is an atmospheric dispersion model used for evaluating releases of hazardous chemical vapors, including toxic gas clouds, fires, and explosions. Using input about the release, ALOHA generates a threat zone estimate. A threat zone is the area where a hazard (such as toxicity, flammability, thermal radiation, or damaging overpressure) is predicted to exceed a user-specified level of concern. Threat zones can also be plotted on maps with MARPLOT to display the location of facilities storing hazardous materials and vulnerable locations (such as hospitals and schools). Specific information about these locations can be extracted from CAMEO information modules to help make decisions about the degree of hazard posed.
For more information, see Downloading, Installing, and Running ALOHA.
The CAMEO software suite consists of four core programs:
CAMEO, CAMEO Chemicals,
MARPLOT, and ALOHA. These programs can be used
together or separately. When the programs are used together, they
interact seamlessly and information can be linked easily between them.
The CAMEO program is a database application that includes several
modules (such as Contacts, Facilities, and Resources) to assist with
data management requirements under the Emergency Planning and Community
Right-to-Know Act (EPCRA). For example, people can use the Facilities
and Chemicals in Inventory modules in CAMEO to store Tier II
information about the chemical facilities in their communities. CAMEO
can also be used to navigate between ALOHA, MARPLOT, and the
downloadable version of CAMEO Chemicals.
CAMEO suite, CAMEO Chemicals is a program that allows users to search for chemicals in the CAMEO chemical database, print customized reports with response recommendations, and find out how chemicals would react if they mixed. This program is available as a website: http://cameochemicals.noaa.gov/ and also as a downloadable program; however, only the downloadable version can share information with other programs in the suite.
For more information (or to get the downloadable version), see the CAMEO Chemicals website.
CERCLIS, or the Comprehensive Environmental Response, Compensation and Liability Information System, contains information on hazardous waste sites, potentially hazardous waste sites and remedial activities across the nation. The database includes sites that are on the National Priorities List (NPL) or being considered for the NPL.
For more information, see CERCLIS Database.
The Chemical Reactivity Worksheet (CRW) is a free program that allows users to investigate the reactivity of substances or mixtures of substances. CRW includes a database of reactivity information for more than 5,000 common hazardous chemicals and offers a way to virtually "mix" chemicals—as well as water—to discover what chemical combinations are reactive. CRW also allows users to build a "Custom Chemical Database" containing all the unique materials that are present at a particular facility. CRW has been upgraded by NOAA to include a new FileMaker Runtime user interface, which makes it compatible with the latest computer operating systems.
For more information, see Chemical Reactivity Worksheet.
LandView® is a DVD and CD-ROM publication of data and maps, jointly issued by the Census Bureau, EPA, United States Geological Survey (USGS), and National Oceanic and Atmospheric Administration (NOAA). For more information, see the Official LandView web site at Census Bureau.
Part of the CAMEO suite, MARPLOT® is a mapping application that people can use to quickly create, view, and modify maps. Users can create their own objects in MARPLOT (e.g., facilities, schools, response assets) and display them on top of a basemap. (There are three basemaps to choose from: standard map files, aerial photos, and topographical maps.) Users can also link objects they've created in MARPLOT to the CAMEO database to store additional information about the objects. For example, users might create an object for a chemical facility in MARPLOT, and then link it to the facility record in CAMEO in order to quickly get info about the facility's chemical inventory during an emergency response.
For more information, please see the Downloading, Installing, and Running MARPLOT.
The National Response Center (NRC), the federal government's national communications center, is staffed 24 hours a day by U.S. Coast Guard officers and marine science technicians and serves as the sole federal point of contact for reporting all hazardous substances and oil spills. The NRC maintains reports of all releases and spills in a national database. To access this information, see the National Response Center: Data Query Page.
RMP*Comp is an electronic tool used to perform the off-site consequence analysis required under the Risk Management Program rule published by the Environmental Protection Agency on July 20, 1996, which implements Section 112(r) of the Clean Air Act. Previously, EPA has referred to this tool as RMP Calculator or RMP Assistant. RMP*Comp makes the same calculations that you can make manually by following the procedures described in EPA’s guidance document, RMP Offsite Consequence Analysis Guidance (April 1999).
For more information, please see RMP*Comp.
RMP*eSubmit is software for facilities to use in submitting Risk Management Plans (RMPs) required under the Risk Management Program. EPA asks that all facilities use this new method to submit RMPs because it is easy to use, will improve data quality, and will enable users to access RMP 24 hours a day, 7 days a week.
Facilities submitting Confidential Business Information (CBI) and Trade Secrets cannot use RMP*eSubmit at this time and must submit using RMP*Submit 2004.
For more information, please see RMP*eSubmit.
EPA developed Tier2 Submit to help facilities prepare an electronic chemical inventory report. Many states accept Tier2 Submit.
For more information, please see Tier II Chemical Inventory Reports / Tier2 Submit.
VZIS to determine whether the address may be in the vulnerable zone of a facility that submitted a Risk Management Plan.
For more information, please see Vulnerable Zone Indicator System.
