Official utility action
Use the utility record to confirm whether the notice represents a known line, a modeled risk, or a still-unverified material category.
Owners avoid direct cost only if the property is selected for the limited Service Line Verification Program and otherwise remain responsible for choosing a contractor and using HELP or another owner-managed payment path.
Do not let a notice flatten the ownership boundary.
Do not overread this notice. The utility's exact category definitions, lookup record, and replacement path still control the real decision.
