Pennsylvania health industry pleads with gas lobby to embrace methane controls

A group representing Pennsylvania doctors, nurses and other health care professionals has sent a letter to the Marcellus Shale Coalition, requesting that it stop legal challenges and lobbying against regulations aimed at controlling drilling air emissions and safeguarding public health. The one-page letter to the shale gas drilling industry’s major Pennsylvania lobbying organization states that…

Study finds higher methane levels as well sites decline in Marcellus in US

A new study shows that background levels of methane in Northeast Pennsylvania in the U.S. increased significantly at a time when well drilling activity decreased, pointing to leaks of natural gas during production and transportation. Researchers from Drexel University found that atmospheric levels of the potent greenhouse gas increased by 100 parts per billion between…

Barnett Shale research raises new concerns about methane emissions

Researchers from the University of Houston found that some natural gas wells, compressor stations and processing plants in the Barnett Shale leak far more methane (CH4) than previously estimated, potentially offsetting the climate benefits of natural gas. The study is one of 11 papers published in the July 7 edition of Environmental Science & Technology,…

Lower than expected pollution seen at Marcellus drilling sites, methane higher: Study

An article in the journal Environmental Science and Technology reports measurements of air pollution from Marcellus drilling and transportation sites in Bradford and Sullivan counties were lower than the researchers expected. The study, “Atmosphere Emission Characterization of Marcellus Shale Natural Gas Development Sites,” also reports levels of methane emissions were higher than those indicated in previous…

Despite better air quality, US emissions from shale gas wells may travel far downwind

Emissions linked to hydraulic fracturing, the method of drilling for natural gas commonly known as “fracking,” can be detected hundreds of miles away in US states that forbid or strictly control the practice, according to a UMD study published in the journal Atmospheric Environment. The study is among the latest data presented in the ongoing…

Colorado enacts first methane leakage capture rules in US

Colorado became the first state in the United States to enact air quality rules that included measures to regulate methane emissions from oil and gas drilling. The Colorado Air Quality Control Commission wrapped up a five-day public hearing on regulations that would target air pollution and smog, approving a plan that was introduced in November…
