NTH developed an air permit application for a 425 MW pulverized coal plant in Manistee, MI for the Tondu Corporation. The power plant would generate electricity for distribution to the electric power grid system. The proposed power plant consisted primarily of a pulverized coal-fired boiler that would generate steam to drive a steam turbine. Other ancillary equipment consisted of coal receiving, storage and handling; bottom and fly ash handling and storage; lime receiving, handling and storage; ammonia receiving and storage; material from the flue gas desulfurization process; auxiliary steam boiler; emergency natural gas-fired generator; and emergency natural gas-fired fire pump.
Project Approach The new electrical generating station would have been subject to the federal PSD regulations, due to its potential emissions being greater than the major source thresholds as defined in the PSD regulations. NTH analyzed the various BACT determinations, and proposed BACT for those new source review pollutants that were subject to BACT. NTH prepared a project description, discussion of the major project equipment, operating scenarios, fuel types, proposed emission controls, process description and flow diagram, proposed emission rates, and exhaust stack parameters.
The new plant would also be impacted by federal MACT and NSPS regulations, and NTH performed analyses of these for the company. Furthermore, extensive mercury control and impacts were addressed based on the MDEQ– AQD’s rules for toxic air contaminants. NTH performed initial deposition modeling to determine the net loading of mercury to the Manistee Lake watershed.
Ultimately, the developer withdrew the permit application after the local municipality denied the required Special Use Permit.
