Failure and O&M Reference Guide St. Mary River Diversion And Conveyance Facilities
In 2006, the SMRWG introduced federal legislation (SB-3563) that was unsuccessful, signaling that the rehabilitation of the St. Mary Facilities was going to take much longer than anticipated. This led to concerns that, due to the aging and deteriorated state of the facilities, failures will increase in frequency and severity with time, and possibly a catastrophic failure of a vital structure that would require an emergency response will occur. Concerns were also leveled about spending large sums of money on structures that will likely be replaced in a few years.
These concerns, expressed by the Milk River Project Joint Board of Control, SMRWG, and the State of Montana, led to formation of the SMRWG Contingency Planning Committee. The committee determined that to be successful, the U. S. Bureau of Reclamation,and the JBOC needed to be active partners in contingency planning. Reclamation and the JBOC were briefed on the concepts behind contingency planning, and amenable to the idea. Informally, this group of stakeholders came to be known collectively as the Catastrophic Failure Planning Team.
