Yes, but it requires formal steps that often take quite a bit of time and consultation with many agencies. Typically, a change to a license condition is completed by license amendment request submitted to the FERC. Depending on the impacts of the change, a license amendment to change a target elevation may include an environmental review and would require approval by all parties who signed the original Settlement Agreement. This includes review and approval of federal and state agencies, who, under the Federal Power Act (FPA, sections 4e and 10j), have the ability to require conditions in the license to adequately protect and ensure utilization of lands owned by the United States (e.g. national forest, tribal lands), and/or provide recommendations to protect, mitigate, or enhance fish and wildlife affected by the operation and management of the hydroelectric project. Per section 10(a)(1) of the FPA, the FERC must be satisfied that the project is adapted as well as possible to a comprehensive plan for developing the waterway.
