There is a reasonable degree of certainty that the impacts to the potentially affected ecosystem (including air, water, plants and animals) are adequately understood, and can be effectively minimized through careful design, management plans and mitigation (including closure) to a degree acceptable to the TRTFN Government. This will normally mean that there have been satisfactory Environmental Assessment and accommodation processes conducted as provided for in the TRTFN Mining Policy. 2. The project is consistent with any TRTFN Government land use plan, or other written land use and development policies or objectives of TRTFN Government for the affected portion of the Territory. 3. There is a management regime for the project in which TRTFN Government has an effective role with respect to the environmental protection measures that need to be implemented in order to maintain environmental quality. 4. There are written agreements as necessary to provide for the measures required for protection of Tlingit land and resources that include a role for TRTFN Government in the conduct of the environmental protection programs throughout the life of the project. 5. The pace of development in Taku River Tlingit Territory is itself sustainable, taking into account potential cumulative impacts from concurrent or consecutive developments, and providing an effective TRTFN Government role in managing the pace of development and avoiding significant cumulative impacts. Economic Sustainability means that: 6. The project is consistent with any long-term economic development goals and strategy of TRTFN Government. 7.
