Good Neighbor Agreement

Stillwater Mining Company’s East Boulder Mine.

The Good Neighbor Agreement is a unique example of a community and a mine working together. For years, Northern Plains members fought Stillwater Mining Company to protect water quality and the communities in Stillwater and Sweetgrass Counties. In 2000, spurred by action taken by Northern Plains members and the prospect of a new mine, the two sides came to the table and negotiated an agreement to extend protections beyond state requirements to protect property, water, and area communities, while allowing platinum and palladium mining to proceed. The legally binding contract developed in these negotiations established a process for citizens to regularly meet with company representatives to address and set strict requirements that prevent problems related to mining impacts, reclamation, wildlife, and other issues. The Good Neighbor Agreement has protected water with robust monitoring and response plans, protected mine-owned land with conservation easements, instituted a busing program to vastly reduce traffic on winding valley roads, and provided for independent environmental audits.

After 17 years under the Good Neighbor Agreement, our members are still working and negotiating with Stillwater Mining Company to develop new strategies to diminish the effects a long-term mine can have on water quality and rural communities.  Today’s major efforts include groundwater monitoring, consistent sampling of surface water and biologic health, and novel technology use and development, particularly in regards to tailings impoundments and waste storage.


  • Provides for citizen oversight of mining operations to ensure protection of the area’s quality of life and productive agricultural land;
  • Establishes clear and enforceable water quality standards that go above and beyond state requirements;
  • Provides local communities with access to critical information about mining operations and the opportunity to address potential problems before they occur;
  • Ensures public safety and security while protecting the interest of miners through traffic plans designed to reduce mining traffic on country roads;
  • Raises the bar for environmental excellence by setting goals and objectives for developing new technologies. This is accomplished through a cooperative framework of local citizens, third-party experts, and the mining company.

The success of the Good Neighbor Agreement depends on the volunteer efforts and commitment of local citizens. The Good Neighbor Agreement is only strong because local Northern Plains members are working with mine representatives to ensure that the solutions envisioned by the Agreement become reality.


Members of Northern Plains can participate in the Good Neighbor Agreement by:

  • Helping take water samples or come to annual biomonitoring to prevent mine activities from having an effect on water quality.
  • Assisting in the efforts of the oversight or responsible mining technology committees.  These members develop our campaigns and work directly with the mine.

If you are interested in working on the agreement, or in volunteering, please email Cameron Clevidence, GNA Manager or call (406) 248-1154.
