Passage of Instrumented Internal Inspection Devices; Limited Suspension of Compliance Dates

Limited Suspension of Enforcement for compliance with final rule.

By final rule published April 12, 1994, RSPA required that new and replaced pipeline facilities be constructed to accommodate inspection by instrumented internal inspection devices commonly known as ``smart pigs.'' Two petitioners requested reconsideration of that rule as it applies to gas pipelines and a stay of the compliance date. In response to these petitions, RSPA issued a Notice of Proposed Rulemaking (NPRM) proposing to modify the rule and extend the compliance dates with respect to certain gas transmission lines. Because of the need to evaluate the numerous comments to proposals in the NPRM, RSPA is unable to complete rulemaking action on that notice by the proposed compliance date with respect to gas transmission lines in less populated areas. This document announces a suspension of enforcement for compliance with the final rule requirements for certain gas transmission lines.
