What Are SEQR Type I and Type II Actions?

Type I Actions

Type I actions meet or exceed thresholds listed in the statewide or agency SEQR regulations. These are likely to require preparation of an EIS. Some examples:

  • nonresidential projects physically altering 10 or more acres of land
  • zoning changes affecting 25 or more acres

Type I actions do not always require an EIS.

Type II Actions

Type II actions are by regulation, those actions which never require further SEQR review.

Unlisted Actions

Unlisted actions do not meet the Type I thresholds but some may still require an EIS. Some examples:

  • nonresidential projects physically altering less than 10 acres of land
  • adoption of regulations, ordinances, local laws and resolutions that may affect the environment
