What standard applies to the transportation of chemicals and explosive materials by pipeline?

• A. 49 CFR Part 192
• B. 49 CFR Part 195
• C. 49 CFR Part 199
• D. 49 CFR Part 198

Answer: (B)

The correct standard that applies to the transportation of hazardous liquids, which include chemicals and explosive materials, by pipeline is 49 CFR Part 195. This regulation specifically outlines the safety requirements for pipelines transporting hazardous liquids and the operational practices necessary to ensure safety during the transportation process.

49 CFR Part 195 covers a wide array of aspects related to the design, construction, operation, and maintenance of hazardous liquids pipelines. It stipulates criteria for ensuring that pipelines are constructed and operated in a manner that minimizes risks associated with leaks and spills, which is particularly crucial when dealing with chemicals and materials that can pose significant safety hazards to the public and the environment.

The other standards referenced in the options, while important in the context of pipeline regulation, do not apply directly to the transportation of hazardous liquids. For instance, 49 CFR Part 192 pertains to the transportation of natural gas and its associated infrastructure, while Part 199 relates to drug and alcohol testing for pipeline employees. Part 198 includes regulations concerning the enforcement of pipeline safety measures, but it does not specifically address the transportation of hazardous materials. Hence, 49 CFR Part 195 is the appropriate standard for transporting chemicals and explosives via pipeline.
