Once all work is completed, when can a certificate be made?

A certificate can only be issued once all work is completed because it serves as an official acknowledgment that all necessary installations, repairs, or modifications have been fully executed to meet the relevant standards and regulations. This ensures that the heating oil tank system is safe and compliant before it is put into operation. Issuing a certificate prematurely, such as after just an initial inspection or assessment, would not provide assurance that all required work has been thoroughly completed and documented, potentially leading to safety and regulatory issues.

This process emphasizes the importance of complete inspection and verification, which are critical in ensuring that tanks are safe for use and do not pose environmental risks.
