  • Do not involve substantative changes to existing monitoring, reporting, or recordkeeping requirements in the permit
  • Do not require or change a case-by-case determination of an emission limitation or other standard, or a source specific determination of ambient impacts, or a visibility or increment analysis
  • Do not seek to establish or change a permit term or condition for which there is no corresponding underlying applicable requirement and that the source has assumed in order to avoid an applicable requirement to which the source would otherwise be subject

  • Are not changes in fuels not represented in the permit application or provided for in the permit
  • The increase in the sources' potential to emit for any regulated pollutant is not significant

  • Changes do not exceed the emission allowed under the permit
  • Changes do not violate any applicable requirement or trigger additional requirements
