The applicant will receive automated emails when the request is moved from the initial review to the technical review, at which stage a deviation request number will also be assigned. 

Yes, the fee is to cover the cost of reviewing the request and is independent of the outcome.

An authorized representative of the company who is responsible for the project and can validate the objectives of the relevant project, can sign the Deviation Request Form. 

The applicant can decide to either alter the design to comply with the requirements of the OESC or in some situations explore a different method to achieve the intent of the OESC. If a deviation request is declined, a subsequent request for that installation would be treated as a new request and would need to follow the process including fees associated with new submissions. 

Before applying for a deviation, you must have a valid ESA customer account. Call ESA at 1-800-746-6480 for assistance with opening an account.

No, the deviation becomes a part of the installation that it is associated with for the rest of its life. For this reason, the submitted requests and review results are retained by ESA for reference at any point in the future. 

No, deviations from the OESC are site and project specific. If a deviation was accepted for a specific site, it cannot be extended to other similar projects at the same or other sites. 

No, the applicant must be the related notification holder and submit the form themselves. To ensure continuity of the information exchange and the accuracy of the review, ESA will only request and/or share information with the applicant.
