Enbridge tightens crude oil pipeline quality standards in North Dakota to address contamination issues

North America's largest liquid pipeline operator, Enbridge Inc., has implemented new quality control standards for its U.S. North Dakota crude oil transportation system to address the recent increase in crude oil contamination within the system. Enbridge has sent official notifications to all shippers using the North Dakota pipeline system, explicitly warning about issues related to the presence of organic chlorides in crude oil. The notification states that if organic chlorides are detected, the pipeline will be immediately shut down. According to sources familiar with the matter, the pipeline experienced a brief shutdown last week due to the discovery of organic chlorides, prompting Enbridge to tighten its quality control requirements after the incident.
