Enviro-Check Updates: 

Changes to the Enviro-Check program now in effect

On August 6, 2021, 2021 Wisconsin Act 78 made several changes to Wisconsin’s environmental compliance audit program’s (Enviro-Check) process. Program staff are working on updating the information to reflect these changes. In the meantime, please contact the program with any questions.

These changes will more closely align Wisconsin’s Enviro-Check program with US EPA’s audit programs. Key changes to the program as a result of Act 78 include:

  • Changing the amount of time a regulated entity has to correct violations identified in an audit from 90 days to 60 days generally, 180 days if the entity is a small business stationary source, and 360 days if the entity is a small business stationary source and the corrective action involves a pollution prevention modification;
  • Eliminating the requirement that an entity must notify the Wisconsin Department of Natural Resources (DNR) no fewer than 30 days before beginning an audit, while still requiring submission of a signed statement prior to beginning the audit acknowledging that violations known before the audit are not eligible for coverage; and
  • Requiring the DNR and Department of Justice (DOJ) to consider whether the entity is a small business stationary source that has committed a minor violation when determining whether to pursue criminal action.

U.S. EPA Voluntary Audit Programs

The U.S. Environmental Protection Agency offers two voluntary compliance audit programs that complement Wisconsin's Enviro-Check program. If you discover any federal regulation violations during your Enviro-Check audit, you can self-report them to the EPA and correct them with limited liability. Keep in mind that Enviro-Check covers any federally delegated regulations contained in Wisconsin statute or administrative codes.

To self-report federal-only violations, please visit EPA’s web pages to learn about EPA's voluntary audit program for businesses of all sizes and a similar program for small businesses:
