February 10, 2009 | 4 40 CFR 60 New Source Performance Standards (NSPS) Hg Limits Subpart Cb Large facilities >250 tons/day; Constructed on or before 9/20/94 Prior to 4/28/09 80 micrograms per dry standard cubic meter or 15 percent of the potential mercury emission concentration (85-percent reduction by weight), corrected to 7 percent oxygen, whichever is less stringent. On or after 4/28/09 50 micrograms per dry standard cubic meter or 15 percent of the potential mercury emission concentration (85-percent reduction by weight), corrected to 7 percent oxygen, whichever is less stringent.

February 10, 2009 | 5 40 CFR 60 New Source Performance Standards (NSPS) Hg Limits Subpart Eb Large facilities >250 tons/day MSW; Constructed after 9/20/94 and on or before 12/19/05 80 micrograms per dry standard cubic meter or 15 percent of the potential mercury emission concentration (85-percent reduction by weight), corrected to 7 percent oxygen, whichever is less stringent. Constructed, reconstructed or modified after 12/19/05 50 micrograms per dry standard cubic meter or 15 percent of the potential mercury emission concentration (85-percent reduction by weight), corrected to 7 percent oxygen, whichever is less stringent.

February 10, 2009 | 6 Florida Administrative Code (3) If mercury control device: 70 micrograms per dry standard cubic meter (ug/DSCM) of flue gas, corrected to 7 percent 0 2, or 20 percent by weight of the mercury in the flue gas upstream of the mercury control device (80 percent reduction by weight), whichever occurs first. Annual testing required. If no mercury control device: 70 ug/DSCM of flue gas, corrected to 7 percent O 2 Staggered semi-annual testing required so at least one unit is test quarterly.
