Oil and Gas Pollution Delivers a One-Two Punch to Our Public Health

One of the country’s largest leaks ever of natural gas, which is primarily made up of the potent greenhouse gas methane, has been going on in California’s Aliso Canyon for over a month. The volume that’s been leaking has been staggering—and the impacts to local residents severe enough to warrant relocating hundreds of families.

Major disasters like the one unfolding in Aliso Canyon have a tendency to grab our attention because the impacts are so acute and can be immediately documented—from the volume of methane that’s leaked (latest climate impacts estimate: equivalent to driving 160,000 cars/year) to the documented health impacts (bloody noses, headaches, breathing difficulties, nausea).

The Aliso Canyon leak, however, also provides us a good reminder of what communities across the U.S. who are close to oil and gas facilities have been increasingly concerned about—the ongoing environmental impact of air pollution that is being released into their neighborhoods, and the safety of those operations. Most of the pollution is invisible to the naked eye, but infrared cameras are bringing the problem into sharper focus, and with that a louder call for action and oversight by federal officials. EPA estimates that today, methane leaks from onshore oil and gas development is contributing climate impacts equivalent to driving nearly 130 million cars annually. And their emissions are contributing to unhealthy air for residents living next door and downwind of this development. Read More »

Four Things To Know About Oil And Gas Methane

1. Methane is a supercharged climate pollutant

Methane is a potent greenhouse gas packing a climate punch 84 times more powerful than carbon dioxide in the first 20 years after it is released. More than a third of the climate impact we feel today is caused by short-lived pollutants, including methane, which accounts for most of that amount. These emissions are worsening already extreme weather patterns responsible for more frequent, higher intensity storms. And, in the absence of action, these trends are expected to accelerate.

 

2. The oil and gas industry is responsible for over 7 million tons of methane pollution

The U.S. oil and gas sector is estimated to release more than 7 million metric tons of methane emissions into the atmosphere each year, according to the Environmental Protection Agency. Read More »

Wyoming Proposal to Curb Venting and Flaring Needs Work

flaringWhen operators pull oil out of the ground, it often comes up with copious amounts of natural gas.  This “associated gas” can be captured and brought to market, creating an additional revenue source for operators.  But if no gathering infrastructure or other methods of capture are deployed, operators either vent the gas to the atmosphere or burn it off with controlled flares. Venting results in the release of methane, a powerful greenhouse gas. Flaring results in troublesome emissions as well, including CO2 and hazardous air pollutants.

According to the Wyoming Oil and gas Conservation Commission (WOGCC), Wyoming’s oil and gas operators vented and flared more than five billion cubic feet of natural gas in 2014.  Five billion cubic feet of gas that could be sold to generate taxes and royalties, heat homes and power machinery across the country, instead was wasted.

Jersey Utility to Use Methane Data Mapped by Google Street View Cars to Target Gas Line Repairs

googlecar2Regulators Bless Plans to Use Information Developed by Environmental Defense Fund and Google in $900M Pipeline Upgrade Program to Improve Safety, Reduce Waste and Cut Greenhouse Gas Emissions

New York and New Jersey, like many older communities in the US, have thousands of miles of old, leak-prone gas lines under their streets, some dating back to the late 1800s. Besides safety concerns, this leaking natural gas – which is mostly methane – is a potent greenhouse gas and a huge waste that’s ultimately paid for by utility customers. While major leaks posing immediate risk are typically fixed quickly, thousands of others can persist for months or years.

Until now, it’s been hard to measure the problem on a large scale, or to use that information to better focus on upgrades with the biggest benefit for the buck. Read More »

A Big Climate Opportunity for Mexico in Dealing with Methane Now

4842884636_c8570c28d7_zMexico is getting good news today about a strategy it can use to help meet its 25% greenhouse gas reduction pledge by 2030. A new report conducted by energy research firm ICF International found that by using available and low-cost technologies, Mexico can cut 54% of its methane emissions from the oil and gas sector for less than one peso per ton of carbon dioxide. Not only does this keep a very potent greenhouse gas out of the atmosphere, methane is 84 times more powerful than CO2 in intensifying warming, but by capturing it, methane is the main ingredient in natural gas, Mexico wastes less energy.

The Mexican government showed leadership in recognizing the importance of reducing short-lived climate pollutants like methane in its climate pledge to the UN Climate Change Conference. And ICF’s study suggests that reductions in oil and gas methane emissions can be a valuable tool as Mexico considers how it will implement policies to meet its goal. Read More »

Recycling Wastewater from Oil and Gas Wells Poses Challenges

15636034581_6f13aaccfc_zEach year, the oil and gas industry produces more than 800 billion gallons of wastewater. Coupling the massive volumes of wastewater generated over the life of the well and the millions of gallons of water needed to hydraulically fracture each well, it’s easy to see that oil and gas exploration and production is just as much a water issue as it is an energy issue.

With growing frequency, this huge volume of oil and gas wastewater – which contains hundreds of chemicals resulting from operations as well as underground water that is usually heavily laden with salt and naturally-occurring pollutants – is being recycled, and some groups are pushing for mandatory recycling policies. Sounds great. After all, recycling is good for the environment, right? Read More »
