What is the manual that addresses operations, maintenance, and emergencies of transmission pipelines?

The correct manual that addresses operations, maintenance, and emergencies of transmission pipelines is found in the regulations set forth in 49 CFR 192.605. This part of the Code of Federal Regulations outlines the requirements for the operation and maintenance of gas pipelines, ensuring that operators maintain safety standards, perform necessary inspections, and address emergencies promptly. Compliance with these regulations is crucial for protecting public safety and the environment.

The other options, while relevant to the pipeline industry, do not specifically focus on the comprehensive operational and maintenance guidelines required for transmission pipelines. For example, API Std. 1173 deals with pipeline safety management systems but does not specifically address operational procedures. API RP 1102 provides guidelines for the construction and installation of liquid pipelines rather than ongoing operations and maintenance. The NCCER Guidelines for Pipeline Safety may include important safety information but are more focused on training and credentials rather than operational regulatory requirements.
