Changes in class location will apply to existing oil pipelines, per the Oil and Gas Pipeline Systems Code Adoption Document.
A pipeline’s class location can change due to population growth and development in a pipeline’s surrounding area. Previously, existing oil pipeline systems were exempted from the requirement to address changes in class location.
Operators of existing oil pipeline systems can submit applications to address changes in class location through one of the following ways:
- Apply for a variance to provide time to upgrade existing pipelines or reduce the operating pressure;
or
- Conduct and submit an engineering assessment to TSSA to determine the suitability of the continued use of the pipeline.
