1. (a) The concentration of organics, expressed as total mass dioxins/furans, contained in the gases discharged to the atmosphere from a MWC unit shall not exceed:

   1. (1) Before April 28, 2009, with electrostatic precipitator: 60 nanograms per dry standard cubic meter (total mass), corrected to 7 percent oxygen.
   2. (2) By April 28, 2009, with electrostatic precipitator: 35 nanograms per dry standard cubic meter (total mass), corrected to 7 percent oxygen.
   3. (3) Without electrostatic precipitator: 30 nanograms per dry standard cubic meter (total mass), corrected to 7 percent oxygen.
2. (b) MWC units that achieve a dioxin/furan emission level less than or equal to 15 nanograms per dry standard cubic meter total mass, corrected to 7 percent oxygen, may elect the alternative performance testing schedule for dioxins/furans as specified in 40 CFR 60.58b(g)(5)(iii).
