What is the purpose of the Notice of Approval (NOA) issued by the permitting agency?

The purpose of the Notice of Approval (NOA) issued by the permitting agency is to allow a system to operate. This document signifies that the permitting agency has reviewed and approved the design of a system, indicating that it meets necessary regulations and safety standards. Once the NOA is issued, it provides official acknowledgment that the system can be permitted for use, ensuring compliance with local health and safety regulations.

Regarding the other options, while some may relate to regulatory processes, they do not capture the essential role of the NOA. For instance, it does not indicate new regulations or confirm a permit denial; instead, it represents approval and enables the system to be put into operation. Additionally, while the NOA does confirm the approval of design plans, its primary function goes beyond just indicating approval regarding design—it grants permission for the system's operational use as well.
