Pipeline Safety: Areas Unusually Sensitive to Environmental Damage **Citation:** 65 FR 80530 **Type / status:** rulemaking / historical **Agency:** Research and Special Programs Administration **Effective / published:** 2001-02-20 / 2000-12-21 This final 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). RSPA created this definition through a series of public workshops, pilot testing, a technical review of the pilot test results, and extensive collaboration with a wide-range of federal, state, public, and industry stakeholders. This final rule does not require specific action by pipeline operators but will be used in existing and future regulations. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `e4bbd86eb27cd826160074ba5e8c8af618ecffd8254fe6eee7278d7ceacb1016` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-00-31756` - Related records: 9 ## 2.
