本地自动翻译 · 来源原始语言
摘要
Duke Energy Gas Transmission Company (DEGT) petitioned the Research and Special Programs Administration's Office of Pipeline Safety (RSPA/OPS) for waiver of compliance with 49 CFR 192.611, which requires natural gas pipeline operators to confirm or revise the maximum allowable operating pressure (MAOP) of a pipeline after a change in class location. DEGT proposed an alternative set of risk control activities in lieu of a reduction in pressure or pressure testing of certain pipeline segments in Pennsylvania in areas that have changed from Class 1 to Class 2.
