OneStop: Our Automated Review Technology

As part of our Integrated Decision Approach, we have changed the way companies apply to the AER. OneStop, our application review technology, dramatically reduces application processing timelines and wait times for companies while improving regulatory oversight.

When an operator submits an application into OneStop, the technology uses a complex set of rules to determine the necessary level of review. Lower risk applications (or components of an application) can be approved automatically through OneStop within minutes, as they’re considered routine with no impact on people or the environment. All other applications (or components of an application) are redirected to technical experts for additional review.
