Title 49 › SUBTITLE VIII — PIPELINES › CHAPTER 601 — SAFETY › § 60142
The Secretary may run short, limited tests of new safety technologies and new ways of operating on natural gas or hazardous liquid pipelines. Each test program can cover at most 5 percent of all miles of hazardous liquid pipelines and 5 percent of all miles of natural gas pipelines regulated by the federal agency or by states. No single operator can test more than the smaller of 38 percent of its regulated system miles or 1,000 miles. Tests cannot take place in high population areas, high consequence areas, or unusually sensitive areas (these are special zone types defined in the pipeline rules). For hazardous liquid pipelines, the Secretary must report to Congress within 1 year about whether testing should be banned in high consequence areas and whether extra protections are needed. Each program can run no more than 3 years from approval, and no new programs may be started after 3 years from the law’s enactment. The Secretary must approve only programs that promise higher safety than current rules. The Secretary can temporarily allow use of technology that existing rules would otherwise block, but only for the length of the test and only for those specific rules. When deciding, the Secretary must look at operators’ accident records, whether they have a safety management system and how it will reduce risks, and whether the technology has already had R&D testing. Participants must send detailed findings to the Secretary. The Secretary must publish a 90‑day public notice before a program, post annual progress online, respond to comments, revoke a participant immediately if testing causes a serious accident or is unsafe or noncompliant, end a program if it conflicts with safety goals, and publish a final report with recommendations. If the final report shows practical standards are possible, the Secretary may create rules to allow and guide use of the new technology.
