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
The Isolated Steel Inspection Program will identify and document sections of isolated steel pipeline (free from cathodic protection), including any isolated service risers, within Avista’s system. Once identified, the goal is to replace each riser or pipeline section within a specified time frame. This program started in Washington State in November of 2011. An established completion date of November 2016 was set for the identification phase of the program and a date of November 2021 was set for the replacement phrase of the program in Washington. Similar inspections are now currently being conducted in Avista’s Oregon service territory. This process will likely run through 2030 as we complete the inspection of 10% of gas services per year for the 90,000 locations identified as part of a program scoping analysis. Isolated steel replacement will likely run beyond 2030 as Avista replaces the identified isolated risers and services.
