Not without considering the historical regulatory framework. Archived records consistently demonstrate that well classifications reflected the directives, manuals, reporting systems and regulatory practices that existed at the time decisions were made. The archive contains numerous examples where engineers sought clarification because current interpretations differed from historical requirements. These differences often reflected changes in regulatory guidance, reporting systems or administrative practices rather than errors in the original classification. The recurring finding is that legacy classifications cannot always be understood properly by applying current expectations without historical context.
