REPORT AN EMERGENCY OR POSSIBLE VIOLATION

WHY PERMITS ARE REQUIRED

Projects affecting water, such as construction near rivers, streams or lakes, may require permits to help make sure the work follows applicable laws and protects water quality, wildlife and aquatic habitat.

Montana’s 310 LAW - The Natural Streambed and Land Preservation Act of 1975

The 310 Law applies to activities that alter or modify the bed or banks of a perennially flowing stream*. A 310 Permit is required for projects that fall under the law. Depending on the project, additional local, state or federal permits may also be required.

Montana's Joint Application Form

Many of these permits use Montana’s Joint Application Form, allowing applicants to enter core project information once and add the additional information required for each permit.

Gilly helps you understand the permitting process, complete the Joint Application Form and work through the additional permit requirements that may apply to your project.
