Montana’s Permitting System —and How Gilly Supports

Learn how Montana’s permitting system works—and why most projects start with the 310 Joint Application.

MONTANA’S PERMIT SYSTEM AT A GLANCE

  • Established by Law

    Montana’s permitting system is established under state law.

  • Protects Water Resources

    Safeguards Montana’s streams, wetlands, floodplains, and other water bodies.

  • Coordinated by Multiple Agencies

    Permit needs vary by project type and location.

UNDERSTANDING THE JOINT APPLICATION

Montana’s Joint Application Form was created to simplify the permitting process for projects being done in Montana’s streams, wetlands, floodplains, and other water bodies, that may need review by more than one agency.

Instead of submitting separate forms to multiple offices, applicants can use a single application that meets the initial requirements of several regulatory partners.

This approach:

  • Saves time and reduces confusion

  • Improves coordination between local, state, and federal agencies

  • Creates a clear path forward for applicants

Several permits may apply depending on where your project is located and the type of work you’re doing. Most projects begin with the 310 Joint Application, reviewed by your local Conservation District.

The 310 Joint Application often acts as a gateway to other required permits.
Gilly was created to streamline the process for both applicants and administrators

    Why It’s Called the 310 Joint Application?

    The Joint Application is one shared form used by several state and federal agencies. It lets you start all your required permits in one place, instead of filling out multiple forms.
