## 1. Pipeline Safety: Standards for Direct Assessment of Gas and Hazardous Liquid Pipelines

**Citation:** 70 FR 61571  
**Type / status:** rulemaking / historical  
**Agency:** Pipeline and Hazardous Materials Safety Administration  
**Effective / published:** 2005-11-25 / 2005-10-25

Under current regulations governing integrity management of gas transmission lines, if an operator uses direct assessment to evaluate corrosion risks, it must carry out the direct assessment according to PHMSA standards. In response to a statutory directive, this Final Rule prescribes similar standards operators must meet when they use direct assessment on certain other onshore gas, hazardous liquid, and carbon dioxide pipelines. PHMSA believes broader application of direct assessment standards will enhance public confidence in the use of direct assessment to assure pipeline safety.
