Pressure Testing Older Hazardous Liquid and Carbon Dioxide Pipelines

Further response to petitions for reconsideration on pressure testing within terminals and tank farms.

This document announces that, while RSPA continues to review requirements for pressure testing older piping within terminals and tank farms, it will not enforce those requirements provided the terminals and tank farms are designed and operated at lower stress levels than the main line. RSPA is evaluating comments received on pressure testing within these areas and is considering modifying the current requirements. The enforcement policy maintains the status quo (that is, no testing required) until a decision is made.
