Shale Boom leads to Increased Air Pollution

Billions of dollars worth of natural gas is wasted each year, says the World Banks’ Global Gas Flaring Reduction Partnership. Gas that could otherwise be used to heat homes, cook food or fuel local economies is instead going up in smoke – burned or flared at oil fields across the world. That flaring produces some 400 million tons of greenhouse gas emissions each year.

Now, preliminary data from World Bank shows that the shale energy boom is fueling a rise in the burning of waste gas. Around the world, gas flaring crept up by 4.5 percent in 2011 – an amount “equivalent to the annual gas use of Denmark” according to a Reuter’s report published yesterday. The World Bank report is due out at the end of the month.

The data indicate that this increase is mostly due to the rise in shale oil exploration in North Dakota, an increase that pushed the US into the top ten gas flaring countries.

Flaring is used to eliminate gas at exploration sites and to test production of the well. The problem is that flaring gas releases a large number of pollutants into the air, including chemicals used to frack the well. In addition to the methane, flaring adds another five dozen chemicals into the air, including: acetalhyde, acrolein, benzene, ethyl benzene, formaldehyde, hexane, naphthalene, propylene, toluene, and xylenes.

Flaring is permitted, but companies could use “greener” technologies that would not only keep these chemicals out of the air but would save money (a savings of $9 for every $1 spent on these technologies according to Deborah Rogers). One tiny detail: these cleaner technologies usually require a gas pipeline to be in place first.

A 2009 report on green completions from SMU explains that companies could capture up to 70% capture of formerly released gases with green completions.

Compressor Station Video

At the recent Cornell Environmental Law Society conference on "Gas Drilling, Sustainability and Energy Policy" it was made very clear that "fracking" is only part of the equation. Along with the drilling and exponential increase in truck traffic, communities will see a lot of infrastructure development. That means pipelines and compressor stations.

If you don't have compressors in your area, here's a video tour to acquaint you.

Does PA have air quality issues caused by gas drilling?

Back in February the mayor from tiny Dish, Texas visited a number of Upstate NY venues to talk about air quality problems associated with gas drilling.  Emissions from the high number of compressors in town have made some people sick.

Now it looks like PA may have a similar problem. This afternoon the PA Department of Environmental Protection (DEP) sent out a notice to the press that the agency is responding to odor complaints in two counties and will be analyzing air quality.

The DEP is gathering samples this week from areas near natural gas operations in Washington and Greene counties. The agency will conduct their study in four phases with each phase lasting one week. They hope to isolate the source of odors that have prompted complaints from residents.

"DEP has received complaints about odors that residents believe are emanating from gas well drilling facilities,” said DEP Southwest Regional Director George Jugovic Jr. Under the Air Pollution Control Act, any entity operating a source of odors may be fined up to $25,000. In the natural gas industry, compressor stations, which are located along natural gas transmission lines and pressurize gas so that it can be piped across great distances, operate under a general permit that limits pollutants by incorporating best available technologies.

During the first phase of the DEP study, their Mobile Analytic Unit will collect and compare air samples from a site in Washington County removed from active drilling as well as active drilling sites in Greene and Washington counties. DEP will also analyze air samples collected over a 24-hour period using 12 canisters, some of which will be placed on the properties of residents who have complained of odors.

Then they will take samples within 3-miles downwind of sites related to gas well drilling in the Marcellus Shale: active drill sites, compressor stations, drip tanks, well heads, gas well flares and wastewater impoundments. They plan to complete sampling by June. 

Samples will be analyzed for volatile organic compounds, ozone, nitrogen oxides, hydrogen sulfide and carbon monoxide. Read more here.
