| 摘要： | Pipelines are arelatively safe mode of transportation for hazardous liquid and natural gas and are regulated by the Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) and state entities. Included in the nation's pipeline network are an estimated 200,000 or more miles of onshore gathering pipelines, which transport products to processing facilities and larger pipelines. Many of these pipelines have not been subject to federal regulation based on their generally rural location and low operating pressures. While incidents involving gathering pipelines regulated by PHMSA have resulted in millions of dollars in property damage in recent years, comparable statistics for federally unregulated gathering pipelines are unknown. This report identifies (1) the safety risks that exist, if any, with onshore hazardous liquid and natural gas gathering pipelines that are not currently under PHMSA regulation and (2) the practices states use to help ensure the safety ofthese pipelines. GAO surveyed state pipeline safety agencies in all 50 states and the District of Columbia; interviewed officials at PHMSA, state pipeline safety agencies, pipeline companies, and industry associations; and analyzed data and regulations. |
