Bushnell hoped to avoid spending the $650,000 for catalytic converters on the engines at its power plant. Mayor Steve Russell said the city keeps the plant as a back-up and doesn't run it regularly.
However, maintaining the power plant brings in $25,000 monthly payments.
Russell said the city buys electricity from a consortium, the Illinois Municipal Electric Agency. The agency makes those payments for the city's generating capacity. One condition is that the power plant meets EPA regulations. New regulations require the installation.
