What federal law mandates pipeline companies to send written reports to the Office of Pipeline Safety?

The correct choice reflects the requirement set forth in federal regulations for pipeline companies to submit written reports detailing certain incidents and operational information to the Office of Pipeline Safety. Specifically, 49 CFR 191.23 outlines the types of information that must be reported, including significant incidents, which can encompass accidents or failures affecting the pipeline system. This regulation helps ensure transparency and accountability within the pipeline industry, aiding in the promotion of safety and environmental protection.

Understanding this requirement emphasizes the importance of maintaining detailed records and reporting protocols, which ultimately contributes to the safe operation of pipeline systems across the country. This is critical for regulatory compliance and for the ongoing efforts to monitor and manage the integrity of pipelines.
