The Michigan Department of Environmental Quality is taking comment through Dec. 1 on a draft air permit for Holland Board of Public Works that would allow some changes at a nearly-completed, combined heat and power plant.
Holland is asking to add two small backup natural gas-fired space heaters to the already-permitted new combined heat and power plant, located at the intersection of East 5th Street and Fairbanks Avenue, Holland, Michigan. Holland is also proposing to eliminate the use of duct burners at the facility and to increase the allowable heat input of the combustion turbine generators (CTGs) by 7%.
Holland submitted an initial Permit to Install (PTI) application for the new plant in 2013. That permit was issued in December 2013. After the designs were finalized, Holland initially asked to modify some exhaust stack parameters and to eliminate a boiler. That permit application did not require a public comment period.
The current PTI application was submitted in August 2016. The DEQ noted: “Construction on the plant is almost complete. The two space heaters will produce minimal emissions of air pollutants and would normally be exempt from permitting requirements if not for being considered part of the entire plant project. They will be used when the rest of the plant is down for maintenance, which is estimated to be only four days per year.”
The new CHP plant has two natural gas-fired combustion turbine generators (CTGs), two heat recovery steam generators (HRSGs), one steam turbine generator, two natural gas-fired auxiliary boilers, one natural gas-fired fuel heater, one natural gas-fired emergency reciprocating engine, one plume-abated wet mechanical draft cooling tower, one emergency diesel-fueled fire pump, four water and condensate storage tanks, one diesel tank, and one aqueous ammonia storage tank.
Holland’s Holland Energy Park project website shows the targeted substantial completion for the 114-MW project is around Dec. 17, with guaranteed substantial completion on Feb. 15, 2017.
