American Municipal Power (AMP) proposes to install eleven 10-MW 4-stroke lean burn natural gas-fired engines in Hamilton, Ohio, to provide peaking power, said a draft permit-to-install for this project issued Nov. 10 by the Ohio Environmental Protection Agency.
Ultimately, AMP will select either 9,700 kW Caterpillar Model G20CM34 or 9,341 kW Wartsila Model 20V34SGD engines for the project, the agency noted. The AMP facility will be located in Butler County which is marginal non-attainment for ozone and non-attainment for PM2.5.
In order to avoid Title V and Major New Source Review requirements, facility-wide natural gas usage will be limited to 2,970 million standard cubic feet (equates to 3,504 operating hours per engine) per rolling, 12-month period. In addition, each engine will be limited to 520 start-ups and 520 shutdowns per rolling, 12-month period. The project does not require netting for PSD since the previous site facility (power plant) will be completely demolished and the site cleared prior to installation of these engines.
Each engine will be equipped with selective catalytic reduction (SCR) to control NOx and an Oxidation Catalyst System to control carbon monoxide (CO) and volatile organic compounds (VOCs). Emission limitations of criteria pollutants are based upon the “worst case” emissions (except SO2) between the two engine models under consideration for the project. SO2 emissions are based upon the Caterpillar engine which reflects the use of domestic fuel.
