Councilperson X: We have an obligation to help ensure that electricity rates are the lowest possible  Since the proposed design for a new generating station would clearly allow for the lowest rates, it must be the design we endorse if we agree that we have no choice but to approve construction of a new plant  Councilperson Y: Helping to ensure the lowest electricity rates is not the council' s only job; we also have an obligation not to lower the quality of life of our community
A plant of the type specified by the design would damage our community' s air quality to such an extent that the benefit of lower rates would be outweighed
A plant of the type specified by the design in question would allow for the lowest electricity rates.
