Frequent Questions

Are systems required to file a report every time an operational evaluation level is exceeded?

Yes. Any time an operational evaluation level is exceeded, the system is required to conduct an evaluation, write a report, and submit it to the state. This could happen at multiple locations or at a single location. The state can reduce the scope of the evaluation at its discretion on a case-by-case basis.
