Compliance and Enforcement Data Systems

Data Systems
Proposed NPDES Electronic Rule

On July 30, 2013 the Proposed NPDES electronic reporting rule was published in the Federal Register.  This rule moves the NPDES program into the 21st Century, shifting from paper to electronic reporting of monitoring and other information.

The information that EPA uses to manage and assess performance of the Agency's enforcement and compliance assurance program is stored in several national data systems. These systems were built to support specific environmental statutes. In general, EPA regions or states input data into the systems.

Enforcement and Compliance History Online (ECHO) or Envirofacts provide the easiest access for the public. Public access to some of the systems listed below may be restricted. If ECHO, Envirofacts, or the other systems described below do not meet your needs, please visit EPA's Freedom of Information Act (FOIA) page to learn how to request additional information.

Air Data Systems

The EPA, with state and local government agencies delegated authority to implement the Clean Air Act stationary source compliance and enforcement program, utilize the Air Facility System (AFS) to track compliance and enforcement activities for stationary sources regulated under the Clean Air Act.

AFS is currently undergoing a modernization project that will be completed in late 2014.  Once the modernization is complete, Clean Air Act stationary source compliance and enforcement program data will be managed in ICIS (Integrated Compliance Information System).

The Applicability Determination Index contains written responses to source owners or operators who need to know whether certain intended actions constitute the commencement of construction, reconstruction, or modification to the New Source Performance Standards (NSPS) in 40 CFR Parts 60 and the National Emission Standards for Hazardous Air Pollutants (NESHAP) in 40 CFR Parts 61 and 63, under the Clean Air Act.

Hazardous Waste Data

The hazardous waste data can be accessed through these data systems:

RCRAInfo provides access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984.

The Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS), or Superfund, database contains general information on sites across the nation and US territories including location, status, contaminants and actions taken. Find information on sites being assessed under the Superfund Program, hazardous waste sites and potential hazardous waste sites, from CERCLIS.

Envirofacts provides public access to data from several EPA data systems. Users can develop on-line queries, create reports and map results.

Multimedia Data Systems and Databases

Multimedia Data Systems and Databases contain data for more than one environmental media:

Enforcement and Compliance History Online (ECHO) is a Web-based tool that provides the public with compliance, permit and demographic data for approximately 800,000 facilities.

Section 7 Tracking System (SSTS), a module within the Pesticide Registration Information System (PRISM), tracks pesticide producing establishments and the amount of pesticides they produce.
