(A) Carbon monoxide: one hundred (100) tons per year.
(B) Nitrogen oxides: forty (40) tons per year.
(C) Sulfur dioxide: forty (40) tons per year.
(D) Particulate matter: twenty-five (25) tons per year.
(E) PM10: fifteen (15) tons per year.
(F) PM2.5: ten (10) tons per year.
(G) Ozone: forty (40) tons per year of VOC.
(H) Lead: six-tenths (0.6) ton per year.
(I) Asbestos: seven one-thousandths (0.007) ton per year.
(J) Beryllium: four ten-thousandths (0.0004) ton per year.
(K) Mercury: one-tenth (0.1) ton per year.
(L) Vinyl chloride: one (1) ton per year.
(M) Fluorides: three (3) tons per year.
(N) Sulfuric acid mist: seven (7) tons per year.
(O) Hydrogen sulfide (H2S): ten (10) tons per year.
(P) Total reduced sulfur (including H2S): ten (10) tons per year.
(Q) Reduced sulfur compounds (including H2S): ten (10) tons per year.
(R) Municipal waste combustor organics (measured as total tetra- through octa-chlorinated dibenzo-p-dioxins and dibenzofurans): thirty-five ten-millionths (0.0000035) or 3.5 × 10-6 ton per year.
(S) Municipal waste combustor metals (measured as particulate matter): fifteen (15) tons per year.
(T) Municipal waste combustor acid gases (measured as sulfur dioxide and hydrogen chloride): forty (40) tons per year.
(U) Municipal solid waste landfills emissions (measured as nonmethane organic compounds): fifty (50) tons per year.
(V) Ozone-depleting substances (ODS): one hundred (100) tons per year.
(W) Pollutant greenhouse gases (GHGs): as specified in subsection (zz).
(X) Any regulated NSR pollutant other than the pollutants listed in this subsection: any emission rate.
(2) Any emissions rate or any net emissions increase associated with a major stationary source or major modification that:
(A) would be constructed within ten (10) kilometers of a Class I area; and
(B) has an impact on the area equal to or greater than one (1) microgram per cubic meter (24-hour average).
(b) "Significant" in reference to a net emissions increase or the potential of a source to emit any of the following pollutants, means a rate of emissions that would equal or exceed any of the following rates:
| |
| Carbon monoxide | 100 tons per year (tpy) |
| Nitrogen oxides | 40 tpy |
| Sulfur dioxide | 40 tpy |
| Particulate matter | 25 tpy |
| PM10 | 15 tpy |
| PM2.5 | 10 tpy |
| Ozone (marginal and moderate areas) | 40 tpy of VOC or oxides of nitrogen (unless a NOX waiver is in effect) |
| Lead | 0.6 tpy |
