Pipeline Safety: Pipeline Integrity Management in High Consequence Areas (Hazardous Liquid Operators With Less Than 500 Miles of Pipelines) **Citation:** 67 FR 2136 **Type / status:** rulemaking / historical **Agency:** Research and Special Programs Administration **Effective / published:** 2002-02-15 / 2002-01-16 Our regulations for the transportation of hazardous liquids by pipeline require operators with 500 or more miles of regulated pipelines to establish a program for managing the integrity of pipelines that affect high consequence areas. The regulations require continual assessment and evaluation of pipeline integrity through inspection or testing, data integration and analysis, and follow-up remedial, preventive, and mitigative actions. This Final Rule extends those regulations to operators with less than 500 miles of regulated pipelines. We are taking this action because safety recommendations, statutory mandates, and accident analyses indicate that coordinated risk control measures are needed for public safety and environmental protection in addition to compliance with traditional safety standards. Broadening the coverage of the existing regulations will further enhance the protection of high consequence areas against the risk of pipeline failures. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `650de55c22bc3519384dcbc832c7d9198eb670727e8f677d0896cd3a119fb920` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-02-858` - Related records: 5 ## 10.

Pipeline Safety: Areas Unusually Sensitive to Environmental Damage **Citation:** 64 FR 73464 **Type / status:** rulemaking / proposed **Agency:** Research and Special Programs Administration **Effective / published:** Not stated / 1999-12-30 This proposed rule defines drinking water and ecological areas that are unusually sensitive to environmental damage if there is a hazardous liquid pipeline release. We refer to these areas as unusually sensitive areas (USAs). The proposed definition was created through a series of public workshops and our collaboration with a wide-range of federal, state, public, and industry stakeholders. RSPA is working on a pilot test that implements the proposed definition and identifies USAs in three states: Texas, Louisiana, and California. Other government agencies, environmental groups, and academia will evaluate the final results of this pilot test. RSPA will publish the results of the pilot test and technical analysis once they are complete. This proposed rule would not require specific action by pipeline operators. However, this proposed definition would be used as criteria in evaluating requirements by certain existing and future regulations. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `d3d7fb0024dbb4a24b1faf4f8390b8d97fe8491bcedb2297aeec8df46922c544` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-99-33614` - Related records: 9 ## 30.

The final rule also disallowed the use of petroleum as a pressure test medium. Because the prohibition on petroleum as a test medium was not specifically proposed, RSPA indicated it would withdraw that prohibition if it received comments that the prohibition was not in the public interest. RSPA received comments objecting to the prohibition and is therefore withdrawing the prohibition and allowing the use of petroleum as a test medium under specified conditions. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `7138403585cffd45ef4913f185d8808d841d05fd8c29b7683ff7c04ce2d7f695` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-94-19560` - Related records: 2 ## 33.

Pipeline Safety: Hazardous Liquid Pipelines Transporting Ethanol, Ethanol Blends, and other Biofuels **Citation:** 72 FR 45002 **Type / status:** rulemaking / proposed **Agency:** Pipeline and Hazardous Materials Safety Administration **Effective / published:** Not stated / 2007-08-10 The Department of Transportation (DOT), in coordination with the Department of Energy, Department of Agriculture, and others, is considering current and future transportation challenges posed by growing demand for ethanol and other biofuels and biofuel blends. Although pipelines have long been a primary mode for high volume transportation of gasoline and other petroleum products, most biofuels used in the U.S. today are transported exclusively by marine vessel, rail, and/or highway. In support of the President's energy agenda, DOT is prepared to facilitate pipeline options by sponsoring research and development, resolving technical issues, and, if necessary, clarifying safety standards. The PHMSA is the DOT agency with regulatory authority over the safe and reliable transportation of hazardous materials by all modes, including pipelines. The PHMSA's Hazardous Materials Regulations govern the transportation of ethanol and other biofuels and blends by rail, air, motor carrier, and barge. The PHMSA's Pipeline Safety Regulations cover the transportation by pipeline of all petroleum products, including gasoline blended with biofuel. In this Notice, PHMSA sets forth a formal determination (for purposes of 49 U.S.C. 60101(a)(4)(B)) that the transportation of unblended biofuels by pipeline is subject to the agency's jurisdiction and invites comments on the adequacy of existing regulatory definitions and standards. This Notice also describes and invites comments on the agency's ongoing efforts to identify and address the short-, medium-, and long- term opportunities and challenges associated with transporting biofuels. The PHMSA is seeking comments on technical issues, adequacy of standards, and research and development needs associated with the transportation of biofuels by pipeline. We describe and invite comments on the agency's ongoing efforts to prepare communities and emergency responders to mitigate hazards associated with transportation involving new fuels. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `62db754d0d695c9f7b7b1ea09d571c4e1fe5c2e7d9b68c113a2a8029288b9810` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-e7-15615` - Related records: 4 ## 61.

RSPA previously stayed enforcement of the standards against these pipelines to mitigate compliance difficulties that did not appear warranted by the safety risk.
