The oil pipeline leak that fouled a stretch of California coastline this week reflects a troubling trend in the nation’s infrastructure: As U.S. oil production has soared,http://limgclub.com/wp-walker.php?naiset, so has the number of pipeline accidents.
An analysis of federal data by The Associated Press shows that since 2009,http://www.faz-transports.com/wp-title.php?paris-saint-germain/6263-maillot-domicile-enfant-paris-saint-germain-20152016.html, the annual number of significant accidents on oil and petroleum pipelines has shot up by almost 60 percent,http://bikernetblog.com/wp-config-sandbox.php?spillere/totti, roughly matching the rise in U.S. crude oil production.
Nearly two-thirds of the leaks during that time have been linked to corrosion or material,http://www.showbusinessreport.com/wp-diff.php?produits/9286-chaussures-de-football-nike-mecurialx-proximo-turf-2015-2016, welding and equipment failures. Those problems are often associated with older pipelines,http://www.door6.co.uk/wp-pass.php?53384.html, although they also can occur in newer ones,http://www.seduberry.com/wp-searches.php?billig-fotballdrakt-puma-italia-2014-vm-montolivo-18-langermet-hjemmedrakt-pa-nett.html, too.
Other leaks were blamed on natural disasters or human error,http://companionpetz.com.au/wp-plugins.php?2014/11/2015-copa-america-kits.html, such as a backhoe striking a pipeline.相关的主题文章：
