MiEnviro Portal: using Site Map Explorer

MiEnviro Portal contains a feature called Site Map Explorer. You can use this feature to explore thousands of publicly available documents and other information.

Use Site Map Explorer to check if a person, business, or facility has a permit. You can search for permit applications, active permits, and violation notices in your area.

Note: While Site Map Explorer provides public access to many documents, it is not intended to be a complete record for a site.  Some older records, such as violations prior to October 1, 2015, and draft documents are not accessible through Site Map Explorer.

Get in-app help, anytime

While using Site Map Explorer within MiEnviro Portal, you can find a "Help" section at any time. Select the  information icon to review the different tools and widgets within the app.

Getting Started

The first screen of Site Map Explorer shows the entire state with many purple dots with a number inside. These dots tell you how many sites are in the vicinity of the middle of that dot. As you zoom in, those dots will turn into more dots with smaller numbers as the area they represent gets smaller.

Eventually the dots will separate out into  individual points, which you may then select to get more information. Not sure how to sort through these results? Keep scrolling!

How to narrow down the results

There are multiple ways to narrow down the results other than zooming in and out on the map.

Use the search bar

While zooming in and out can help narrow down results in a specific area, the search bar can be used to narrow results regardless of location.

Keywords can be generic terms such as boardwalk, seawall, or fill; or, they may be names of entities, such as MSU, Dow, or McLaren. This will narrow the results very quickly.

Use the advanced search criteria

The advanced search feature allows you to input specific search criteria such as an evaluation number, site number, or SIC code. You may also search by address, including zip code.

Using the zip code feature here rather than the simple search bar ensures results returned are in the zip code of your choosing.

Use filters to select multiple categories

Narrow your results even further by using the filters to search by categories such as active permits, applications currently in process, compliance notices, escalated enforcement, and county.

Combine multiple filter choices to find exactly what you're looking for.

Finding information about a specific site

Once you've narrowed the search results down and have located the site you're interested in, selecting that site will bring up its site profile. You may need to select "show more information" to fully expand the menu. Keep scrolling to learn what's included.
