Pennsylvania law okays treated coal-mining water for frac jobs

Pennsylvania Gov. Tom Wolf signed into law a bill intended to encourage more oil and gas companies to use treated coal-mine wastewater for hydraulic fracturing . The law was scheduled to become effective in December. Consol Energy operates coal mines in southwestern Pennsylvania as well as developing and producing natural gas from the Marcellus and Utica shales . Consol Energy already had used wastewaste from its coal mines for fracturing, a company spokesman said. The new law is intended to encourage other gas operators to use treated mine water instead of fresh water. The use of mine water for fracing was among recommendations made by former Gov. Tom Corbett’s Marcellus Shale Advisory Commission. In 2013, the Pennsylvania Department of Environmental Protection issued a white paper to promote the practice. Pennsylvania Department of Environmental Protection officials supported the legislation. Previously, oil and gas companies were reluctant to use treated mine […]

Have We Reached A “Peak Water” Tipping Point In California?

It may be a see-saw course, but it’s riding an uphill train. A bit ago I wrote , regarding climate and tipping points: The concept of “tipping point” — a change beyond which there’s no turning back — comes up a lot in climate discussions. An obvious tipping point involves polar ice. If the earth keeps warming — both in the atmosphere and in the ocean — at some point a full and permanent melt of Arctic and Antarctic ice is inevitable. Permanent ice first started forming in the Antarctic about 35 million years ago, thanks to global cooling which crossed a tipping point for ice formation. That’s not very long ago. During the 200 million years before that, the earth was too warm for permanent ice to form, at least as far as we know. We’re now going the other direction, rewarming the earth, and permanent ice is […]
