Wisconsin incorporates by reference the federal regulations for New Source Review (NSR) Permitting; however, the state adds further requirements.

A summary of the additional requirements includes the following:

• A net emission increase or the potential of a source to emit any of the following pollutants, a rate of emissions that would equal or exceed any of the following:
  • Carbon monoxide —100 tons per year (tons per year).
  • Nitrogen oxides — 40 tons per year.
  • Sulfur dioxide — 40 tons per year.
  • Particulate matter — 25 tons per year.
  • PM₁₀ — 15 tons per year.
  • PM_2.5 — 10 tons per year; 40 tons per year for nitrogen oxides; and 40 tons per year for sulfur dioxide.
  • Ozone — 40 tons per year of VOC or 40 tons per year of nitrogen oxides.
  • Lead — 0.60 tons per year.
• PM_2.5 emission increases may be offset by decreases in nitrogen oxides or sulfur dioxide emissions, that are otherwise creditable, at a ratio of 40 tons per year of sulfur dioxide for each ton of direct PM_2.5 emissions and 200 tons per year of nitrogen oxides for each ton of direct PM_2.5 emissions.
