310 Permit Information
Montana’s Natural Streambed and Land Preservation Act, also known as the 310 Law, is a state law which requires that any person planning to work in or near a perennial stream or river on private land must first obtain a 310 Permit from the local conservation district. The purpose of the 310 Law is to insure that projects on perennial streams will be carried out in ways that are not damaging to the stream, its banks or to adjoining landowners.
The Glacier County Conservation District (GCCD) administers the 310 law in Glacier County. GCCD retains jurisdiction over all perennial streams plus a few sensitive non-perennial streams as well. If in doubt about whether your stream is affected, check with us. There is no fee for the 310 permit. It is possible that other permits are required by other agencies.
What kinds of activities require a permit?
- Stream crossings (culverts, bridges, fords)
- Streambank protection projects (stabilization, “riprap”)
- Docks, boat ramps
- Diversions
- Channel changes, dredging
- Trenching in utility lines or pipelines
- New dams, reservoirs, ponds
A permit may also be required if an existing project needs repairs and/or alterations. Rules change through time, so be sure your methods are up to date.
In Case of Emergency
The 310 Law contains a provision to handle actions necessary to safeguard life or property, including growing crops, during emergencies. The emergency form is available on this Web site or from the GCCD office. We encourage you to notify us immediately in an emergency. Our supervisors can help you make the best decisions for you and for our water resources. If you must take emergency action, notify the GCCD in writing within 15 days of the action taken explaining what was done and why. The emergency action will be reviewed by the GCCD, which will decide whether the action was appropriate, must be modified, or must be removed and/or replaced.
You can download an emergency form from this Web site, or contact the GCCD.
Activities without a Permit
It is a misdemeanor to initiate a project without a permit; to conduct activities outside the scope of the permit, to violate emergency procedures, or to use prohibited materials in a project. Upon conviction of a misdemeanor, a person may be punished by a fine up to $500 or by a civil penalty not to exceed $500 per day for each day the person continues to alter the stream. In addition, at the discretion of the court, the person may be required to restore the damaged stream as recommended by the GCCD to as near its prior condition as possible.
If you would like to report an activity that may be a violation of the 310 law, please fill out the complaint/violation form and mail it to the GCCD. You can download a complaint/violation form from this Web site, or contact the GCCD.
