Not exact matches

New natural gas pipelines do not face the same kind of opposition as oil pipelines because the product is a gas and, in case of a leak, it escapes into the atmosphere rather than fouling waterways and soil.

Estimates vary widely on just how much methane is leaked from the vast network of oil and gas wells, pipelines and processing plants, but the problem has cast doubt on how much better natural gas is than coal for the environment.

Studies that have compared safety records have typically determined that trains have far higher accident rates involving hazardous materials than do pipelines, although leaks from railcars tend to be more quickly contained.

But InsideClimate News recently reported that the leak detection systems used on most of the nation's pipelines rarely detect spills smaller than 1 percent of the pipeline's flow, which for the Keystone XL would be hundreds of thousands of gallons per day.

Enbridge alone has had more than 800 leaks in its pipeline network going back just over a decade.

(Pipelines leak methane at much higher rates than previously understood, and methane is much more dangerous to the environment than carbon dioxide.)

When the new emissions data were combined with current pipeline mileage information, significant regional variations were observed, with the Eastern region of the United States accounting for more than a third of the total U.S. emissions from pipeline leaks, and the larger western region, where systems tend to be newer, contributing 17 percent of total emissions.

Since these gases are leaking as they are piped to the surface, rather than seeping up through the ground from deep fracking sites, improving the integrity of drill holes and pipelines could curb the problem of water pollution.

Phillips should know: Last year, his research team found the city of Boston's pipeline distribution system had more than 3,000 leaks.

The government also earmarked more than $ 10 billion for water improvement measures, including more efficient farm irrigation methods and new pipelines that significantly reduce losses due to leaks.

In January, for example, a leaking pipeline spewed more than 11 million liters (2.9 million gallons) of fracking wastewater.

Information has continued to pile up confirming many of the concerns raised by NRDC and other environmental groups: pipelines moving tar sands are more likely to leak, leak detection systems are unlikely to detect tar sands spills when they happen, tar sands spills are significantly more damaging than conventional spills, and conventional spills response measures are inadequate for containing and cleaning tar sands spills.

Rather than taking action to hold the company accountable, they were allowed to move forward with an even bigger and more flawed pipeline plan (Keystone XL) that would put both Canada and the U.S. at risk of a massive oil leak or spill.

Under long - standing regulations, they said, it would be «in the public interest,» even though science has recently made it clear that the methane leaking from the fracked gas the pipeline will carry is worse than the burning of coal.

Included in life cycle carbon are substantial methane leaks from natural gas production and pipelines, the energy for drilling, mining, transport, refining, and disposal that are much more significant for fossil fuels and nuclear energy than for renewables.

This pipeline transports bitumen - loaded tar sands oil, which is more corrosive than oil extracted through other methods — which means much higher risk of leaks.

Tar sands pipelines are also far more likely to leak than conventional oil pipelines, which spells bad news for Sebago Lake, Casco Bay, and 11 pristine New England rivers.

In March, pipeline corrosion caused a leak of more than 200,000 gallons of oil, the worst spill since production began on Alaska's North Slope [see previous post].

Older pipelines, which have undergone decades of wear and corrosion, can be more prone to leaks, and thus less safe, than new pipelines — especially pipelines carrying corrosive dilbit at higher temperatures.

A year later, more than 1,500 barrels leaked from another of Enbridge's pipelines in Canada's Northwest Territories.

Stopping the Keystone XL pipeline is important not just because it will help stop future leaks that, judging from the track record of TransCanada's first pipeline, Keystone 1, as highlighted above, will be much larger than the spills we've seen from rail transport, but it also prevents a massive piece of essentially permanent fossil fuel infrastructure from being established that will no doubt push global warming past the point of no return, as the «terrifying math of global warming» makes startlingly clear.
