An earlier final rule made the applicability of these requirements unclear. Additional changes to the regulations remove incorrect cross-references, clarify fire drill requirements, and require reviews of plans and procedures. Lastly, the final rule changes the regulations so that cross-references to the National Fire Protection Association standard, NFPA 59A, refer to the 2001 edition of that standard rather than the 1996 edition. These clarifications and changes will improve the clarity and effectiveness of the regulations. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `e84ea306a3f012bf37f19314d2c3b337c261bb48d3684167ee7c7f979c53c127` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-04-4857` - Related records: 37 ## 6.

Gas Gathering Line Definition; Alternative Definition for Onshore Lines and Proposed Safety Standards **Citation:** 70 FR 57536 **Type / status:** rulemaking / proposed **Agency:** Pipeline and Hazardous Materials Safety Administration **Effective / published:** Not stated / 2005-10-03 On September 25, 1991, DOT published a notice of proposed rulemaking to revise the definition of "gathering line" in its gas pipeline safety standards. Because the proposal proved controversial, final action was postponed pending collection of additional information. In this Supplemental Notice of Proposed Rulemaking (SNPRM), PHMSA is proposing use of a consensus standard to distinguish onshore gathering lines. PHMSA's gas pipeline safety standards do not provide an adequate basis for distinguishing these pipelines from production facilities and transmission lines. In addition, PHMSA is proposing to establish safety standards for certain higher-risk onshore gathering lines, and to relax current standards on certain low-risk onshore gathering lines. (Onshore gathering lines in inlets of the Gulf of Mexico are not affected by this rulemaking.) Operators would use a new risk-based approach to determine which of its gathering lines are "regulated onshore gathering lines" and what safety standards the lines must meet. At present, PHMSA's safety standards do not apply to onshore gathering lines in rural locations, while onshore gathering lines in non-rural locations must meet the same requirements as transmission lines. This regulatory approach is insufficient to assure that conditions on gathering lines that pose a greater risk to the public and property are addressed. And it does not take into account the lower risk some other gathering lines pose. The intended effects of the proposed rules are improved identification of gathering lines, improved public confidence in the safety of gathering lines, and safety requirements better tailored to gathering line risks. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `0e8b7360133c690eb158a4e6477d7c63724ef4276956844962b705d688241adf` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-05-19455` - Related records: 17 ## 14.

In response to a statutory directive, this Final Rule prescribes similar standards operators must meet when they use direct assessment on certain other onshore gas, hazardous liquid, and carbon dioxide pipelines. PHMSA believes broader application of direct assessment standards will enhance public confidence in the use of direct assessment to assure pipeline safety. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `f3fdd0ee51a9fe21c2d8e6856217495d8326f899bdebfe8436d06c213efe1d7d` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-05-21233` - Related records: 10 ## 15.

Pipeline Safety: Control Room Management/Human Factors **Citation:** 73 FR 53076 **Type / status:** rulemaking / proposed **Agency:** Pipeline and Hazardous Materials Safety Administration **Effective / published:** Not stated / 2008-09-12 PHMSA proposes to revise the Federal pipeline safety regulations to address human factors and other components of control room management. The proposed rules would require operators of hazardous liquid pipelines, gas pipelines, and liquefied natural gas (LNG) facilities to amend their existing written operations and maintenance procedures, operator qualification (OQ) programs, and emergency plans to assure controllers and control room management practices and procedures used maintain pipeline safety and integrity. This proposed rule results from a PHMSA study of controllers and controller performance issues known as the Controller Certification Project (CCERT), a National Transportation Safety Board study, safety- related condition reports, operator visits and inspections, and inquiries. This rule would improve opportunities to reduce risk through more effective control of pipelines and require the human factors management plan mandated by the Pipeline Inspection, Protection, Enforcement, and Safety Act of 2006 (PIPES Act). These regulations would enhance pipeline safety by coupling strengthened control room management, including automated control systems, with improved controller training and qualifications and fatigue management. PHMSA expects these regulations will complement efforts already underway in the pipeline industry to address human factors and control room management, such as the development of new national consensus standards, including an American Petroleum Institute (API) recommended practices on roles and responsibilities, shift operations, management of change, fatigue management, alarm management and SCADA display standard, as well as comparable business practices at some pipeline companies. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `8696b2b8f38aa7657a27f89b172ef0a565127ec16e556bbf834b1171f6673a93` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-e8-20701` - Related records: 23 ## 35.

That susceptibility comes from the plate and pipe manufacturing and is broader than previously understood; recent data and incident investigations indicate that hard spots could affect multiple pipelines manufactured prior to 1970. Hard spots, if not identified and mitigated, pose a threat to the integrity of the pipeline from interacting threats such as coating degradation, soil chemistry, and/or increased hydrogen exposure, which can result in hydrogen-induced cracking. Pipeline owners and operators should consider expanding their hard spot threat evaluation to all pipe manufactured prior to 1970, regardless of manufacturer; collecting and analyzing data associated with hard spot magnetic flux leakage in-line inspection tools; and following industry best practices when conducting in-line inspection data analysis. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `2ebff5d4b9572441e2c357405e939e775a9f9457061e33f08646073ad84fb450` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-2024-26725` - Related records: 5 ## 37.

AGA's request to clarify the rule by deleting language in the regulation concerning sizing of the EFV and locating the EFV beyond the hard surface is granted because some operators are apparently misinterpreting this language. AGA's request to delete the recommended installation standards from the performance standards rule and include them in the notification rulemaking is denied because such standards are applicable to an EFV's safe and reliable operation. AGA's request to allow an operator to determine how to identify the presence of an EFV in the service line is denied because the final rule already allows the operator this flexibility. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `ddf25a6f4c473449a31ca4302a5066a4bcde76805f20303f20d1be0392bc7da9` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-97-1249` - Related records: 1 ## 84.

Pipeline Safety: Control Room Management/Human Factors **Citation:** 74 FR 63310 **Type / status:** rulemaking / historical **Agency:** Pipeline and Hazardous Materials Safety Administration **Effective / published:** 2010-02-01 / 2009-12-03 PHMSA is amending the Federal pipeline safety regulations to address human factors and other aspects of control room management for pipelines where controllers use supervisory control and data acquisition (SCADA) systems. Under the final rule, affected pipeline operators must define the roles and responsibilities of controllers and provide controllers with the necessary information, training, and processes to fulfill these responsibilities. Operators must also implement methods to prevent controller fatigue. The final rule further requires operators to manage SCADA alarms, assure control room considerations are taken into account when changing pipeline equipment or configurations, and review reportable incidents or accidents to determine whether control room actions contributed to the event. Hazardous liquid and gas pipelines are often monitored in a control room by controllers using computer-based equipment, such as a SCADA system, that records and displays operational information about the pipeline system, such as pressures, flow rates, and valve positions. Some SCADA systems are used by controllers to operate pipeline equipment, while, in other cases, controllers may dispatch other personnel to operate equipment in the field. These monitoring and control actions, whether via SCADA system commands or direction to field personnel, are a principal means of managing pipeline operation. This rule improves opportunities to reduce risk through more effective control of pipelines. It further requires the statutorily mandated human factors management. These regulations will enhance pipeline safety by coupling strengthened control room management with improved controller training and fatigue management. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `1a57600142eb3277022bfa95030ec4276290846847e791a5b9cb9dea5f9715b2` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-e9-28469` - Related records: 16 ## 99.
