Archived Rulemaking: Transportation of Natural and Other Gas by Pipeline; Hot Taps in Gas Pipelines

47-fr-25555.pdf (506.93 KB)

By Notice 1, MTB proposed that operators be required to determine the pressure in a pressurized pipeline before allowing the gas to flow through a newly made branch connection into another pipeline. The proposed rule was intended to preclude overpressurization hazards that can arise when two pipelines are erroneously connected. Although all commenters supported the safety objective to be attained, the proposed rule would be unnecessary in some cases, and MTB does not have enough historical accident data or other information about the potential for future accidents to clearly demonstrate that the expected benefits of the proposed rule would outweigh the costs of implementation. As a consequence, the proposed rulemaking action is hereby withdrawn.
