The Federal Energy Regulatory Commission’s Integrated Licensing Process (ILP) is the newest licensing process for hydroelectric projects and is being implemented around the US today. The first license application filed under the ILP was submitted in December, 2006 by PPL Montana for the Mystic Lake Hydroelectric Project. The identification, evaluation and management of archaeological and historical (cultural) resources is an essential element of all hydroelectric licensing studies today. This paper details how the management of these non-renewable resources was made a part of the ILP on the Mystic Lake Project.
