1 Tonawanda Community, Clean Air Coalition, NYSDEC, USEPA and Tonawanda Coke Corp. AWMA February, 2016 Tonawanda Coke early 1900’s TCC History • First coke ovens put in service in 1917 • 60 ovens Semet-Solvay Design • 1926 added second battery of 60 ovens • Primary customers Wickwire-Spencer Steel and Tonawanda iron • Appx 30 million cubic feet of coke oven gas sold daily to Iroquois Gas Company • 1961, # 2 battery taken out of service and a new battery consisting of 60 four meter ovens of Wilputte gun fired, hairpin, cross-regenerative design constructed. This battery is the one in operation today. The original 1917 battery became inactive in 1972 • Allied chemical owned the facility. • December 1977 fire of a large tar storage tank nearly destroyed the facility. • Jan 1978 J.D. Crane purchased the 188 acre site and continued operation as Tonawanda Coke co, (TCC) • Operating as a merchant facility producing foundry coke • Tonawanda Coke supplies foundry coke to the U.S. and Canadian foundry, insulation and sugar beet industries 4 NYS Department of Environmental Conservation WYORK Department of 1fR%NITY Environmental Conservation Major Sources • • • • Tonawanda Coke NOCO Energy Sunoco Terminal Huntley Stream Generating Plant • 3M O-Cello • • • • • Tonawanda GM DuPont Indeck Yerkes Goodyear Dunlop FMC Active Oxidants NYS Department of Environmental Conservation NYS Department of Environmental Conservation Benzene alley NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation NYS Department of Environmental Conservation Applicable regulations • 6NYCRR part 214 by-product coke oven batteries • Effective 1984,, versions dating back to 1982 • Standards for coal charging, coke pushing and transport, quench towers, waste heat stacks, oven doors, charging hole lids and offtake piping, coke oven gas sulfur recovery. • Rule written to address PM nonattainment issues NYS Department of Environmental Conservation • 1984 Consent order giving TCC alternate compliance stds inlieu of pushing controls • More stringent door leak, coal charging limitations. • Facility limited to foundry coke production NYS Department of Environmental Conservation Applicable federal regulations • 40 cfr part 61, subpart V, June 6, 1984, national emission stds for equipment leaks.

(FR 4/15/2005). NYS Department of Environmental Conservation Tonawanda Application Staff from BAQAR, BAQS, BOSS and Region 9 drafted a monitoring plan and completed the application. Goals • • • • Evaluate National Emission Inventory for Tonawanda Evaluate EPA's modeling results at census tract level Evaluate Residual Risk Assessment for Coke Oven NESHAP Provide foundation for future community participation Plan • Collect monitoring data from 4 sites for 1 year • Analyze pollutant specific data – min/max facility influence from wind direction data • Determine spatial variations – upwind versus downwind NYS Department of Environmental Conservation Contaminants to be monitored • 44 VOC compounds – 11 are HAPs • 11 Carbonyl compounds – 2 are HAPs, formaldehyde & acetaldehyde • PM2.5 • Sulfur dioxide • Carbon disulfide NYS Department of Environmental Conservation 6 Locating the Monitoring Sites Benzene 12 month average Concentration µg/m3 12.00 2007 State annual average 3 AGC -
