Also on December 11, OPS announced their intent to approve a waiver to allow Duke Energy to increase the allowable operating pressure in the fifteen pipe segments who had experienced class location increases. The risk control activities include:
- Internally inspect the waiver segments using geometry and magnetic flux leakage in-line inspection tools.
- Internally inspect approximately 166 miles of additional pipe on the three parallel lines in the Mt. Pleasant Discharge.
- Investigate dents upon completion of the dent inspections for an extended length of pipe (the "extended segments") bordering and including each waiver segment to further extend the benefits of the integrity analysis.
- Repair indications of corrosion, existing construction damage, and existing outside force damage identified by the internal inspection using conservative investigation and repair criteria.
- Perform hydrostatic tests of the portions of Line 10 which have not previously been tested to 100 percent (SMYS). This includes two of the waiver segments.
- Implement a Communications Plan designed to inform and educate appropriate stakeholders and Duke Energy employees about risk management concepts and the purposes and expected benefits of the Duke Energy Demonstration Project.
- Perform enhanced damage prevention activities including implementing selected recommendations from a recent study of one-call systems and damage prevention programs best practice, "Common Ground". Duke will also install, for a trial period, the TransWave monitoring system covering all of the waiver segments. This system will be tested to determine its reliability and usefulness for detecting third-party encroachments (construction, excavation, etc.) in the pipeline right-of-way.
