| 摘要： | A mature pipeline network exists in the Gulf of Mexico to transport oil and gas production from the Outer Continental Shelf (OCS) to shore. Virtually all Federal OCS production is transported to shore via pipelines, with the exception of a relatively small amount that is barged from shallow water. While there is still significant pipeline construction, most new OCS pipelines connect to existing pipelines offshore. The number of new pipeline construction projects resulting in new landfalls, where a pipeline crosses a States shoreline, continues to decline. The Minerals Management Service (MMS) projected the number of new pipelines landfalls that may result from a proposed lease sale in order to analyze the potential impacts to wetlands and other coastal habitats. The final environmental impact statement (EIS) for the proposed Western and Central Planning Area 2007-2012 lease sales, published in April 2007, stated that up to one (i.e., zero to one) new pipeline landfall is projected per proposed lease sale (USDOI, MMS, 2007a), meaning that some individual sales may result in no new landfalls. The information presented in this report was obtained from MMSs Technical Information Management System (TIMS) (USDOI, MMS, 2007b). Only pipelines that originated offshore, transported Federal OCS production, and crossed a States shoreline were considered Federal OCS pipeline landfalls. If a Federal pipeline was constructed that connected with an existing State pipeline that made landfall, it was not considered as a Federal OCS pipeline landfall. Existing or proposed pipelines that transport imported gas from offshore LNG terminals were also not considered Federal OCS pipeline landfalls. The date of a pipelines initial hydrostatic test was used for the date of installation. As existing infrastructure ages or is damaged, there is a possibility that some existing pipelines. |
