The Indiana Department of Environmental Management is taking comment until Sept. 27 on a draft air permit for Zimmerman Energy LLC for a landfill gas-fired power plant at Argos, Ind.
“Zimmerman Energy, LLC, plant number 049-00038, is a power plant that will produce electricity using landfill gas provided by the County Line Landfill Partnership’s County Line Landfill, plant number 049-00029,” said the draft permit.
IDEM said it finds that the Zimmerman Energy plant and the County Line Landfill plant do not meet all three parts of the major source definition and therefore the two plants are not part of the same major source.
The Zimmerman Energy stationary source consists of four Caterpillar Model G3520C 1500 rpm 4-stroke lean burn Internal Combustion (IC) Engines with a power generation rating of 2,740 brake horsepower (bhp), identified as ENG01-ENG04, approved for construction in 2013, firing landfill gas (LFG) from County Line Landfill as a primary fuel, utilizing pipeline Natural Gas as a backup fuel. It will have a maximum heat input capacity of 18.7 MMBtu/hr (Lower Heating Value) each, equipped with an air-to-fuel ratio controller and exhausting to stack S01-S04 respectively. Each engine will be connected to 1,966 kW electricity generators.
