License Articles and Conditions The FERC license contains 61 Articles  Currently we have identified approximately 350 tasks for the life of the  project (50 years). Approximately 120 tasks have been identified that have compliance  deadlines between July 2013 and July 2015. The 350 and 120 tasks identified above do not include tasks associated  with the BLM R/W, 401 rulings, ACOE 404 conditions, HPA conditions or any pre, during or post Engineering or Operations assignments. We anticipate that there will be between 500 and 1000 tasks once all the  conditions are analyzed.
