HOW GILLY MAKES IT EASIER

Gilly guides you through the permit application process, explains what information is needed and saves your progress as you go.

Montana uses one shared form, called the Joint Application, for several stream-related permits. If additional permits apply, you can reuse your core project information and add only what those permits require.

For a 310 Permit, your local Conservation District reviews the application and can help identify whether other permits may also apply.
