What is isolated steel?
Buried steel pipelines are monitored to ensure that adequate protection measures are in place so the pipe does not deteriorate or corrode. Isolated steel are sections of steel pipe or steel service risers found without adequate protection. These facilities require additional mitigation or potentially replacement to ensure adequate protection measures are in place to prevent deterioration or corrosion of the steel material.
Isolated steel inspections
Isolated steel inspections are performed at the meter and service riser in order to identify sections of isolated steel pipeline, including any isolated service risers, within Avista’s system.
Once identified these locations are evaluated and mitigated by re-establishing cathodic protection or replacing existing pipe.

If we missed you, we will leave a door hanger with the inspector’s contact information, requesting a call back to schedule an inspection appointment.
