The failed proposal would require certain Montana coal-fired unit operators to keep local cities supplied with water after a unit closes or retires.
Operators of Montana coal-fired units with at least 200 megawatts would provide water for the local city or town if the unit closes or retires.
Cleanup plans would show financial protection for the local water supply 30 years after final remediation; cost savings could not guide conveyance maintenance or replacement decisions.
A coal-fired generating unit operator would provide water for the city or town where the unit is located. The duty covers residential and business water use and applies to coal-fired generating units in Montana with at least 200 megawatts of generating capacity. If the operator owns or operates a conveyance needed to maintain the public water system, the operator would operate that conveyance and provide access to the needed water. The operator would continue this access until contamination from the unit or its waste impoundments meets the department's cleanup standards at the required compliance point. The water-supply duty would apply if the generating unit closes or permanently retires, and conveyance operation and water access would continue until the stated cleanup standard is met.
A cleanup plan for a coal-fired generating unit would have to show financial assurance for the needed local water supply. The requirement applies to remediation under the coal-cleanup law and covers the water supply, operation, and access needed by the local government served by the unit. The assurance would cover the necessary water supply 30 years after final remediation of the unit's operation and access. The department could not consider cost-effectiveness when evaluating maintenance or replacement of a water-supply conveyance under the proposed water-access section. The financial assurance would address the water supply 30 years after final remediation of the unit's operation and access.
