The Integrated Compliance Information System (ICIS) supports the information needs of the national enforcement and compliance program as well as the unique needs of the National Pollutant Discharge Elimination System (NPDES) program. ICIS will integrate data that is currently located in several separate data systems.
Regional Air Impact Modeling Initiative(RAIMI)
The U.S. Environmental Protection Agency (EPA), Region 6, established the Regional Air Impact Modeling Initiative (RAIMI) to evaluate the potential for health impacts as a result of exposure to multiple contaminants from multiple sources, at a community level of resolution.
Enforcement and Compliance History Online(ECHO)
ECHO is a Web-based tool that provides the public with compliance, permit and demographic data for approximately 800,000 facilities.
GIS Screening Tool (GISST)
The GISST is a tool used to assess environmental vulnerabilities and impacts using GIS data and a decision structure. It is a format similar to the HRI and EJ methodologies and was developed in a pilot project beginning in 1996. The method evaluates characteristics such as soil permeability, erosion potential, soil type, landuse-land cover, stream miles, distance to surface water, ground water quality, and rainfall for a determined geographic area. The GISST can evaluate single media and cumulative impacts for environmental assessment projects (e.g., NEPA, compliance assistance, etc.).
Several documents are available for those interested in applying GISST:
