Pipeline Safety: High Consequence Areas For Gas Transmission Pipelines **Citation:** 67 FR 50824 **Type / status:** rulemaking / historical **Agency:** Research and Special Programs Administration **Effective / published:** 2002-09-05 / 2002-08-06 This final rule defines areas of high consequence where the potential consequences of a gas pipeline accident may be significant or may do considerable harm to people and their property. The definition includes: current class 3 and 4 locations; facilities with persons who are mobility-impaired, confined, or hard to evacuate, and places where people gather for recreational and other purposes. For facilities with mobility-impaired, confined, or hard-to-evacuate persons and places where people gather, the corridor of protection from the pipeline is 300 feet, 660 feet or 1000 feet depending on the pipeline's diameter and operating pressure. This final rule is the first step in a two-step process to develop integrity management program requirements for gas transmission operators. In the second step, the Research and Special Programs Administration (RSPA) will propose requirements to improve the integrity of gas transmission pipelines located in these high consequence areas. This definition satisfies, in part, the Congressional mandate in 49 U.S.C. 60109 for RSPA to prescribe standards that establish criteria for identifying each gas pipeline facility located in a high-density population area. RSPA developed the definition from the comments received on the notice of proposed rulemaking, and the earlier notice that invited public comment about integrity management concepts as they relate to gas pipelines. The definition does not yet require any specific action by gas transmission pipeline operators. Action will not be required until we issue integrity management program requirements that use the definition. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `f7a505e550dbef1b45b678d20abdc3d38ae9121f982d89a76de94c96ac4fbcc6` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-02-19840` - Related records: 8 ## 2.
