Rationale and scope:

Hot Tap Field inspection to verify TransCanada/NGTL preventative measures implemented following hot tap tee failure (INC2014-062 - workmanship-related deficiencies, inadequate working conditions, and failure to follow QA/QC process for hot tap installations led to the incident). Company has implemented a number of preventative actions to avoid similar incidents, including: -modifying and/or introducing a number of checklists/ inspection plans (e.g. Third Party Surveillance Checklist for Pressure Containing Split-Tees, Pipeline Hot Tap Stub Installation Form, Weld NDE Matrix) -requiring a senior welding technologist on site to provide training to welders, and to ensure NDE is conducted properly -increasing the excavation area prior to in-service welding to provide sufficient access for welders and inspectors -increasing size of run-on/ run- off welding tabs to prevent indications and defects at the end of the fitting. **TC Energy is the parent company to Trans Canada Pipelines Ltd. Trans Canada Pipeline Ltd is the name on the original Order for the pipeline and facilities**
