The purpose of the PPG is to present Reclamation’s risk informed decision-making (RIDM) framework for evaluating high and significant hazard potential dams, determining the need for action, and prioritizing investigations and modifications to Reclamation dams. Reclamation first issued guidelines for RIDM in 1997. The guidelines were revised in 2003 and again in 2011. Updates included in the current draft document have been made based on experience gained since the development of the 2011 PPG in the interest of not only improving guidance but providing a document that is consistent with the way Reclamation currently applies the RIDM process. The document and instructions for submitting comments can be accessed here.
