Current through Register Vol. 50, No. 11, November 20, 2024

Section V-30193 - Additional Requirements for Carbon Dioxide Pipelines

A. Vents 1. Carbon dioxide may not be relieved into the atmosphere of a building or other confined space where hazardous levels of carbon dioxide might accumulate above the human exposure level set by the United States Department of Labor, Occupational Safety and Health Administration as depicted in the following table, unless the appropriate respiratory protection is provided.

Condition	Minimum Respiratory Protection Required above 5000 vppm
Gas concentration 50,000 vppm or less	Any supplied air respirator or self-contained respirator.
Greater than 50,000 vppm or entry and escape from unknown concentrations	Self-contained breathing apparatus with a full face-piece operated in pressure demand or other positive pressure mode. A combination respirator which includes a Type C supplied-air respirator with a full face-piece operated in pressure-demand or positive pressure or continuous flow mode and an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive pressure mode.
Fire Fighting	Self-contained breathing apparatus with a full face-piece operated in pressure-demand or other positive pressure mode.
Escape	Any escape self-contained breathing apparatus

2. except for the reporting requirements of Subchapter B of this Subpart see §30199, transportation of a hazardous liquid through a pipeline by gravity; [49 CFR 195.1(b)(2)]

B. Sensing Devices

1. Each operator shall determine the appropriate location for and install sensing devices necessary to monitor the operation of components used in transporting carbon dioxide to detect malfunction which could cause a hazardous condition if permitted to continue; and

2. Buildings in which potentially hazardous quantities of carbon dioxide may exist must be continuously monitored by carbon dioxide sensing devices set to activate audible and visual alarms in the building and at the control center.

C. Fail-Safe Control

1. Control systems for components on carbon dioxide pipelines must have a fail-safe design where practical from good engineering practice. A safe condition must be maintained until personnel take appropriate action either to reactivate the component served or to prevent a hazard from occurring.

D. Sources of Power

1. Electrical control systems, means of communication, emergency lighting and firefighting systems must have at least two sources of power which function so that failure of one source does not affect the capability of the other source.

2. Where auxiliary generators are used as a second source of electrical power, they must be located apart or protected from components so that they are not unusable during a controllable emergency, and the fuel supply must be protected from hazards.
