Learn more about EDGE

The Economic Development and Green Environment (EDGE) pilot program was enacted in the fall of 2017 to provide incentives for manufacturers who participate in the Green Tier program, locate on a site with an environmental cleanup and are eligible for Registration Operation Permits for air emissions.

Green Tier

Green Tier is the state's flagship program to support and recognize businesses who go beyond compliance. The voluntary program acknowledges and supports those who develop an environmental management system (EMS) to drive their decision making and environmental performance. In addition to developing an EMS, each participant must create annual reports to document their continual improvement and commit to having their system audited by a third party.

Information about the Green Tier program, including benefits, commitments, fact sheets, and lists of participants are available on the Green Tier web page.

Brownfields Redevelopment

To participate in the pilot, an environmental cleanup must have been conducted on the property where the facility is located. The cleanup needs to meet the requirements of the Voluntary Party Liability Exemption (VPLE) program and receive a Certificate of Completion from DNR.

Information about the VPLE program, including forms, fact sheets, and lists of properties that have participated in VPLE are available on the VPLE web page

Air Management

Any facility that meets the above criteria and is eligible for a Registration Operation Permit, is not required to make changes to the air pollution controls for their stationary source, even with new or modified legal requirements (except for Federal requirements) for 10 years after DNR grants coverage under a Registration Operation Permit (ROP).

As a result of the EDGE program, DNR has developed the Green Tier Registration Permit, or ROP-G. The ROP-G is the largest registration permit available and is only available to Tier 2 participants regardless of their EDGE participation. This permit reduces regulatory oversight, making it easier to commit capital, make changes and get products to market quickly without going through the administrative process of filing and renewing permits.

Information about the Registration Operation Permits, including forms, applications, and fact sheets are available on the Registration Permits web page.
