Regulator Temporary Field Authorizations

As of August 2019, most temporary field authorizations issued by the AER are now called regulator temporary field authorizations, and the disposition code has changed from TFA to RTF, except for geophysical exploration and certain oilsands exploration and coal exploration activities that are not in OneStop.


Our estimated processing time for this application is 5 business days. See our timeline spreadsheet for updates.

Purpose of the Application

Companies must apply for temporary field authorizations to

  • respond to client requests for incidental clearings or activities on public land,
  • respond to temporary changes in existing land disposition authorizations, or
  • temporarily authorize appropriate land uses on public lands.

Process Checklist

Companies must submit their application for a regulator temporary field authorization through OneStop. Spatial information (shapefiles) and all other supporting documentation will be required as part of the application. 

To submit a manual temporary field authorization for activities outside of OneStop, see the Temporary Field Authorization form on our website, > Rules and Directives > AER Forms > Public Lands Act Forms
