What type of maintenance inspection program has a set scope outlined by regulations?

The correct answer is a type of maintenance inspection program characterized by having a set scope defined by regulations. This means that such programs must adhere to specific legal requirements and guidelines that outline what needs to be inspected, how often inspections should be conducted, and the standards that must be met.

Discretionary maintenance inspection programs, as the correct choice, allow for a flexibility in approach but are still required to follow certain regulatory frameworks. These regulations help ensure consistent safety and compliance across projects.

In contrast, general maintenance protocols are often broader and may not be strictly regulated, while limited maintenance inspection programs focus on specific areas without comprehensive conditions laid out by regulations. Comprehensive sewage maintenance strategies, meanwhile, are typically more specialized and may not pertain to the general framework of inspection programs.
