In response to FERC`s order, City Light sought and obtained an extension of at least 18 months to allow it to engage in a negotiated comprehensive scheme, on which all parties to the re-licensing process had agreed. Overall, the city has tried to streamline a complex process. Every intervener had the right to question FERC independently, to question, in a sense, the use of City Light and to compel it to respond to the reasons why it had not considered such measures. This approach could, and often, lead to hostile and unfriendly relations, and the chances of a fair settlement were slim. It turned out that City Light and the various parties, including the Park Service, saw the benefits of an agreement and agreed to negotiate an agreement that would then be submitted for FERC approval.  In 2002, the parties agreed to a transaction. NoAA Fisheries issued a biological opinion in 2003 on Chinook salmon and LCR-Coho salmon from the Lower Columbia River (LCR), followed by a second advisory in 2007, following the LCR-Coho salmon list and the designation of a critical habitat for LCR ok salmon and the LCRChino steel head. PGE discontinued the licence and removed the Marmot Dam in October 2007 and the Little Sandy Dam in 2008, improving access to approximately 90 miles of historic habitat for salmon species. The removal of dams contributes to the restoration of classified species by improving habitat conditions and restoring the natural flow of water.
In November 2006, the 59 MW project was approved by the Federal Energy Regulatory Commission for a period of 50 years. The project is located on Lake Chelan, a 50 mile lake of exquisite aesthetic charm that offers a unique setting for a long period of summer recreation, fishing opportunities, an irrigation water source for the surrounding orchards and vineyards, domestic water for neighboring communities. The lake also serves as a reservoir that supplies two water generators to the Chelan Falls Powerhouse. In 1981, the Park sought legal advice from the law firm on its authority over such projects. What the managers learned was basically what they already knew. The park service`s ability to regulate dams and hydroelectric projects in and near areas of the national park was hardly absolute and, in many respects, uncertain.
