Which of the following actions comes last in the OSSF permitting process?

In the OSSF permitting process, the last action taken is the inspection. This step is crucial because it ensures that the installation adheres to all regulations and project specifications. During the inspection, the authorities verify that the system has been constructed correctly and is ready for use. This final validation step is essential to confirm that the facility meets all health and safety standards before it can be authorized for operation.

The other actions, such as submitting for a permit, system planning, and issuing an authorization to construct, occur earlier in the process. System planning lays the groundwork by evaluating the site's suitability and determining the appropriate system design. After planning, the process continues with submitting the application for the permit, followed by the issuance of authorization to construct, allowing the work to begin. Only after the system has been constructed will an inspection take place to finalize the permitting process.
