Pipeline Safety: Grant of Waiver; Maritimes & Northeast Pipeline, L.L.C.
PHMSA is granting Maritimes & Northeast Pipeline, L.L.C. (M&N) a waiver of compliance from certain PHMSA regulations for the United States portion of its pipeline system. This waiver increases the maximum allowable operating pressure (MAOP) for the pipeline. This waiver decision also authorizes M&N to increase the design factor for its compressor station piping, grants relief from the strength testing requirements for M&N's compressor station piping, grants relief in establishing the MAOP of pipelines operating above prescribed hoop stresses, grants relief from the capacity requirements of pressure limiting stations, and authorizes M&N to maintain the pressure rating of portions of the waiver area subject to a change in class location. Before granting the waiver, PHMSA performed a thorough technical review of M&N's application and supporting documents. PHMSA requested and received supplementary information on numerous technical aspects of M&N's design, engineering, operations, and maintenance practices. The materials are available in docket PHMSA-2006-23448 at https:// dms.dot.gov. PHMSA also sought comments from the public and received positive feedback from States along the pipeline and the Technical Pipeline Safety Standards Committee. The waiver is subject to and conditional upon supplemental safety criteria set forth in this notice. The supplemental safety criteria address the life-cycle management of the subject pipeline and require M&N to adhere to maintenance, inspection, monitoring, control, and reporting standards exceeding existing regulatory requirements.
Pipeline Safety: Grant of Waiver; Alliance Pipeline L.P.
PHMSA is granting Alliance Pipeline L.P. (APL) a waiver of compliance from certain PHMSA regulations for the United States portion of its pipeline system. This waiver increases the maximum allowable operating pressure (MAOP) for its pipeline. It also increases the design factor for its compressor station piping, grants relief from the hydrostatic testing requirements for its compressor station piping, and grants relief from equipment requirements for pressure relieving and limiting stations. Before granting the waiver, PHMSA performed a thorough technical review of APL's application for waiver and supporting documents. PHMSA requested and received supplementary information pertaining to numerous technical aspects of APL's design, engineering, operations, and maintenance practices. PHMSA also sought comments from the public and received positive feedback from the impacted States along the pipeline and the Technical Pipeline Safety Standards Committee. The waiver is subject to and conditional upon supplemental safety criteria set forth in this notice. The supplemental safety criteria address the life cycle management of the subject pipeline and require the operator to adhere to maintenance, inspection, monitoring, control, and reporting standards exceeding existing regulatory requirements.
Pipeline Safety: Grant of Waiver; Rockies Express Pipeline
PHMSA is granting Rockies Express Pipeline, L.L.C. (Rockies Express) a waiver of compliance from the pipeline safety regulation that prescribes the design factor to be used in the design formula for steel pipe. This waiver allows the Rockies Express pipeline to operate at hoop stresses up to 80 percent of the specified minimum yield strength (SMYS) in Class 1 locations. The waiver also grants Rockies Express relief from equipment requirements for pressure relieving and limiting stations. Before granting the waiver, PHMSA performed a thorough technical review of Rockies Express's application and supporting documents. PHMSA requested and received supplementary information pertaining to numerous technical aspects of its metallurgy, pipeline design, and engineering practices. These materials are available in the docket PHMSA-2006-23998 at https://dms.dot.gov. PHMSA also sought comments from the public and received positive feedback from the impacted States along the pipeline and the Technical Pipeline Safety Standards Committee. The waiver is subject to and conditional upon supplemental safety criteria set forth in this notice. The supplemental safety criteria address the life cycle management of the subject pipeline and require Rockies Express to adhere to maintenance, inspection, monitoring, control, and reporting standards exceeding existing regulatory requirements.
