The Ohio Environmental Protection Agency on Dec. 5 issued a draft permit-to-install (PTI) that would allow Ohio State University to replace a coal-fired boiler with new gas- and oil-fired capacity.
“The Ohio State University (OSU) has requested an initial PTI for a new natural gas and #2 fuel oil fired 206 MMBtu boiler that is replacing a coal-fired boiler,” said the draft PTI. “The coal-fired boiler (B131) was removed from service in 2005. The permit includes synthetic minor operational restrictions that take into consideration the emissions from two PBR emergency generators (B266 & B267) that were installed as part of the project scope for the replacement of boiler B131 (hospital expansion project). The synthetic minor restrictions are being established for the purpose of avoiding the 40 [tons per year] for NOX, 40 TPY for SO2 and 10 TPY for PM2.5 significant emissions increases for a major modification under NANSR (Note that although Franklin County is currently designated as attainment for NOX and SO2, NOX is regulated as a precursor for ozone and SO2 is regulated as a precursor for PM2.5).”
Existing at the Ohio State facilities are B266 and B267, which burn only #2 distillate fuel oil, and B270, which has the operational capability to burn either #2 distillate fuel oil or natural gas.
