# SUPPLEMENTARY INFORMATION:

                    On October 18, 2010, (75 FR 63774), PHMSA published an ANPRM seeking comments on the need for changes to the regulations covering hazardous liquid onshore pipelines. In particular, PHMSA is interested in knowing whether it should extend regulation to certain pipelines currently exempt from regulation; whether other areas along a pipeline should be identified for extra protection or be included as additional high consequences areas (HCAs) for Integrity Management (IM) protection; whether to establish and/or adopt standards and procedures for minimum leak detection requirements for all pipelines; whether to require the installation of emergency flow restricting devices (EFRDs) in certain areas; whether revised valve spacing requirements are needed on new construction or existing pipelines; whether repair timeframes should be specified for pipeline segments in areas outside the HCAs that are assessed as part of IM; and whether to establish and/or adopt standards and procedures for improving the methods of preventing, detecting, assessing and remediating stress corrosion cracking in                           ( print page 304)                        hazardous liquid pipeline systems. On November 15, 2010, the American Petroleum Institute and the Association of Oil Pipe Lines requested PHMSA to extend the ANPRM comment period deadline a minimum of 60 days to give their members sufficient time to respond to this ANPRM. Likewise, on November 29, 2010, Texas Oil and Gas Association requested extension of the comment period a minimum of 60 days. PHMSA has concurred, in part, with these requests and has extended the comment period from January 18, 2011, to February 18, 2011. This extension will provide sufficient time for submission of comments concerning this ANPRM.                

Issued in Washington, DC, on December 23, 2010.

Deputy Associate Administrator for Policy and Programs.
