Pipeline Safety: Hazardous Liquid Pipeline Accident Reporting Revisions **Citation:** 66 FR 15681 **Type / status:** rulemaking / proposed **Agency:** Research and Special Programs Administration **Effective / published:** Not stated / 2001-03-20 This notice of proposed rulemaking would amend the pipeline safety regulations to lower the reporting threshold for hazardous liquid pipeline spills from 50 barrels to 5 gallons. We are also seeking comments on revisions to the hazardous liquid accident form to improve its usefulness. On the revised accident form, reporting for spills from 5 gallons to less than 5 barrels will require minimal information. The improvements to the hazardous liquid accident form are necessary to address known deficiencies in the current information collection. The improved information on failure cause categories and more detailed information about the impact of failed pipelines will improve pipeline safety statistics, increasing the overall usefulness of the data and making analysis more efficient and meaningful. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `d6b1a0ff4f79e38c0c3655718c23355f44b800227a133421aa599e3aa7733c8f` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-01-6822` - Related records: 2 ## 29. Pipeline Safety: Pipeline Integrity Management in High Consequence Areas (Hazardous Liquid Operators With Less Than 500 Miles of Pipelines) **Citation:** 66 FR 15821 **Type / status:** rulemaking / proposed **Agency:** Research and Special Programs Administration **Effective / published:** Not stated / 2001-03-21 This proposed rule extends the requirements for protection of populated areas, commercially navigable waterways, and areas unusually sensitive to environmental damage from hazardous liquid pipeline spills to those regulated hazardous liquid pipeline operators who own or operate less than 500 miles of pipeline. This action is necessary because on December 01, 2000, RSPA's Office of Pipeline Safety (OPS) issued a final rule to establish new requirements for the protection of these areas. However, the published final rule applied only to hazardous liquid pipeline operators who own or operate 500 or more miles of pipeline. After further review, it was determined that the same requirements should be extended to the remaining regulated hazardous liquid pipeline operators. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `9a9190219bca22eee3275933b0c486dd9125beebf448303a57f7cb5b9bee93c2` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-01-6821` - Related records: 1 ## 30.

In addition, this final rule revises the requirements for intermediate bulk containers and UN portable tanks for alignment with international requirements. Because of recent changes to the International Maritime Dangerous Goods Code (IMDG Code), the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions), and the United Nations Recommendations on the Transport of Dangerous Goods (UN Recommendations), these revisions are necessary to facilitate the transport of hazardous materials in international commerce. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `f0ee9d766ccc08ccaeefe66668b2fafabe0a42d34556fd94a81a3c9a51b9fc8f` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-01-13836` - Related records: 109 ## 31.

Applicability of the Hazardous Materials Regulations to Loading, Unloading, and Storage **Citation:** 66 FR 32420 **Type / status:** rulemaking / proposed **Agency:** Research and Special Programs Administration **Effective / published:** Not stated / 2001-06-14 RSPA is proposing to clarify the applicability of the Hazardous Materials Regulations (HMR) to specific functions and activities, including hazardous materials loading and unloading operations and storage of hazardous materials during transportation. We propose to list in the HMR pre-transportation and transportation functions to which the HMR apply. Pre-transportation functions are functions performed to prepare hazardous materials for movement in commerce by persons who offer a hazardous material for transportation or cause a hazardous material to be transported. Transportation functions are functions performed as part of the actual movement of hazardous materials in commerce, including loading, unloading, and storage of hazardous materials that is incidental to their movement. We propose to clarify that "transportation in commerce," for purposes of applicability of the HMR, begins when a carrier takes possession of a hazardous material and continues until the carrier delivers the package containing the hazardous material to its destination as indicated on shipping papers. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `83215fdb0b062eddd9e0e7f3b05bb62a0189f4073a503091fd4296bbe97a13ca` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-01-14385` - Related records: 43 ## 33.

To provide laboratories lead-time to accomplish the transition to the new CCF, the Department, in coordination with HHS, has determined that earlier compliance with this reporting procedure should be permitted. Additionally, the Department is also permitting early compliance with the reporting of all non-negative results to the MRO using faxed or scanned copies of the laboratory copy of the new CCF. This document authorizes HHS certified laboratories to initiate electronic reporting as the only reporting necessary for negative results on specimens submitted to laboratories using the new CCF and the reporting of non-negative results using faxed or scanned copies of Copy 1 of the new CCF. Laboratories may continue to use current procedures utilizing mail or courier services. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `4ff6a531b8b2013e7e50f869cfbae650a8af6e83dd59b6619e05167b8d0acb94` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-01-12484` - Related records: 1 ## 34.
