Michigan Dept. of Environment, Great Lakes, and EnergyThis data shows the location and specific information about Supplemental Environmental Projects in Michigan. A Supplemental Environmental Project or SEP is a voluntary project undertaken by a company as part of an enforcement action. This project creates a way for the company in non-compliance to give back to the impacted community and defers some of their settlement payment. You can access specific information about various projects, such as the type of project and nexus created by the project (air quality, lighting upgrade, vegetative barrier and more), where the project was, how much the project cost, and information about the enforcement case that led to the project being developed. You can also view this data and related information in our Supplemental Environmental Projects and Air Quality Enforcement Viewer ( item details ).
