Anomaly Assessment and Repair Workshop

On October 22, PHMSA and the Interstate Natural Gas Association of America (INGAA) co-sponsored and facilitated a public workshop on Assessment and Repair of Anomalies in Pipelines at the Gaylord National Hotel in National Harbor (Oxon Hill), Maryland. Approximately 175 attendees representing Federal and State regulators, industry, researchers, manufacturers, vendors, and the public from both the United States and Canada attended the workshop. The current regulations contained in 49 CFR 192.485 and 192.713, allows latitude in methods used for assessing and remediating pipe with corrosion anomalies to restore the serviceability of pipe. PHMSA has found a wide variation in operators' interpretation of how to meet the requirements of pipeline safety regulations in assessing, evaluating, and remediating corrosion anomalies. The workshop allowed the review and discussion of appropriate repair criteria for evaluating anomalies to meet regulatory code requirements for the permanent field repair of imperfections and damages. The workshop also allowed attendees to discuss the implications of research results and the potential need for regulatory changes or modification of industry standards.
