Pipeline Safety

This page provides a table of contents for all of MRSC's content related to transmission pipeline safety.


Since the 1999 Olympic Pipeline disaster in Bellingham, many local governments in the State of Washington have become aware of and concerned about the major natural gas and hazardous liquid pipelines that cross through our communities. Larger diameter pipelines that transport large volumes of natural gas or hazardous liquids under high pressure are classified as transmission pipelines.

Please note that these pages deal with natural gas and hazardous liquid transmission pipelines, not distribution pipelines. Distribution pipelines are the much smaller diameter pipelines that carry natural gas to homes and small businesses in many communities.

Additional information can be found on the pipeline safety webpages maintained by the Washington State Utility and Transportation Commission (UTC) and the Pipeline Safety Trust. Through certification by Office of Pipeline Safety, the Utilities and Transportation Commission inspects, and enforces intrastate gas and liquid pipeline safety requirements. By signed agreement with OPS, the UTC also inspects interstate liquid and gas pipeline safety requirements. The Pipeline Safety Trust in Bellingham is an oversight organization created by Bellingham residents to ensure safer pipelines nationwide. It is funded by an endowment from the criminal fines imposed after the Bellingham pipeline disaster. The Trust promotes fuel transportation safety through education and advocacy, by increasing access to information, and by building partnerships with residents, safety advocates, government, and industry, that result in safer communities and a healthier environment.
