Supplemental Environmental Projects

When the AQD enters into an enforcement action with a facility, the action typically results in a legally binding agreement between the State of Michigan and the facility which contains a monetary penalty, a compliance plan, and sometimes a Supplemental Environmental Project (SEP). An SEP is an environmentally beneficial project that is not required by state or federal law, but an alleged violator agrees to undertake as part of a settlement of an enforcement action. SEPs are projects that go beyond what is legally required to return to compliance with applicable state and federal laws.

Properly developed and administered SEPs have the potential to secure significant improvements in environmental quality and public health for Michigan citizens and can promote an atmosphere of cooperation between the alleged violator and the affected community benefiting from the projects. In lieu of payment of a portion of the monetary fines, an alleged violator may propose a SEP as part of the settlement. Although a settlement may include a SEP, monetary fines are a necessary and important part of any settlement.

Example SEPs

An SEP can take various forms and the facility involved in the enforcement action will develop the SEP. AQD will review and approve the SEP before it is implemented by the facility. An SEP must meet one or more of the following categories:

  • pollution prevention and reduction
  • environmental restoration and protection
  • public health
  • environmental assessments and awareness
  • climate change mitigation and preparedness
  • emergency planning and preparedness

A few examples are included below with the SEP categories met by conducting the project. More historical Air Quality SEP Summaries have also been included.

Environmental Restoration and Protection Project in Detroit

Aerial view of Clark Park in Detroit, MichiganThe city of Detroit will spend $89,200 as part of a settlement on a vegetative buffer at Clark Park.

The project will reduce the transport of particulate matter emissions from vehicles on I-75 to the adjacent park.
Trees will be planted, and the city will conduct two years of maintenance on the trees including fertilizing, weeding, mulching, and watering.




Pollution Prevention and Reduction Project in Albion

A street light in Albion, MichiganKnauf Insulation spent $103,000 as part of a settlement on street lighting replacement.

This project included recycling and proper disposal of the existing lights and replacing them with more energy efficient LED lights. This will result in a reduction in overall electrical demand, therefore reducing emissions associated with electricity generation.




Public Health Project in Dearborn

Salina Intermediate and Elementary Schools in Dearborn, MichiganAK Steel spent $337,000 as part of a settlement on an active air filtration project at Salina Intermediate and Elementary Schools.

This project improved indoor air quality by removing more particles, gaseous odors, and volatile organic compounds than the schools' previous passive filters.




Community Input

EGLE encourages community input on SEPs from the local community that may have been adversely affected by the alleged violations. Soliciting community input during the SEP development process can better address the needs of the affected community, promote environmental justice, produce better community understanding of the resolution of the alleged violations, and foster partnership with the community members.

Seeking community input early in the SEP development process is beneficial for developing a SEP that addresses the needs and concerns of the affected community and environment. Both EGLE staff and the alleged violator can seek community input on SEP ideas collaboratively. The extent of community input and participation in the SEP development process will vary with each settlement.
