The sequence is broadly the same across the state, and every step generates a record:
A failing system follows the same path, but starts from the recorded as-built: the existing tank, field footprint and reserve area constrain what can be built. Which is why pulling the original record is the cheapest first step in any repair.
Lenders and, in many counties, point-of-transfer rules require an inspection. Inspectors work from the recorded as-built; without it they are probing blind and the inspection costs more and proves less.
