R Stamp Work in a State With Extra Requirements
A repair organization in State A holds an NBBI R stamp and repairs a watertube boiler installed in State B. State B requires the repair organization to notify the state boiler section before any welded repair and to use an inspector licensed by State B. The shop's QC manual and its NBIC training say the authorized inspector may come from its own National Board-commissioned inspection agency. The shop's inspector is commissioned by the National Board but not licensed in State B. The shop completed a weld repair on a superheater tube, issued an R-1 report, and sent it to the owner. State B's inspector later rejects the repair and orders the boiler shut down. The shop argues that its R stamp is valid nationwide and that State B cannot impose extra requirements. The owner faces a production outage and asks what should have been done.
1. Which requirements govern this repair: the R stamp, NBIC, or State B's rules? Explain the hierarchy.

All three matter, but they operate differently. The R stamp is the National Board accreditation that allows the organization to perform repairs and alterations under NBIC. NBIC provides the technical and quality requirements. State B's rules are legal requirements because the boiler is installed there, and NBIC itself requires compliance with the jurisdiction. An R stamp does not preempt state licensing, notification, or inspector requirements.
The shop was therefore wrong to treat the R stamp as a nationwide authorization that overrides State B. The shop needed to meet the R stamp and NBIC requirements and also satisfy State B's prior-notification and licensed-inspector rules. If State B requires a state-licensed inspector, a National Board commission alone is not enough for that jurisdiction.
2. What should the shop have done before starting the superheater repair?

Before mobilizing, the shop should have verified State B's requirements: whether prior notification or approval was required, which inspector credentials were accepted, and what report forms and filing deadlines applied. It should have confirmed that the assigned inspector was licensed in State B, or arranged for a state-licensed inspector. It should also have reviewed its QC manual and work package to include the state requirements and hold points.
If State B required notification before welded repair, the shop should have submitted the notification and waited for authorization. The shop should have documented the jurisdiction review in the job file. A purchase order or owner request to proceed quickly would not excuse skipping the state requirements.
3. What corrective actions are needed now to resolve the rejection and prevent recurrence?
Read the worked answer
The shop should stop work on the boiler, cooperate with State B's inspector, and provide the repair records, welding procedure, NDE results, and R-1 report for review. It should arrange for a State B-licensed inspector to examine the repair and follow the state's direction on rework, additional examination, or acceptance. The owner should be kept informed of the actual status; the existing R-1 may need to be revised or supplemented once the state accepts the work.
Preventive action should include adding a jurisdiction-review step to the QC manual and job checklist, verifying inspector licensing before assignment, training staff that the R stamp is not a substitute for state requirements, and auditing other repairs performed in States with similar rules. The shop should also correct its claim that State B cannot impose extra requirements.
