EnergyWire reports that a review of spill records indicates that spills declined about 17 percent during 2016 compared to the previous year. The decrease makes sense to Lauren Patterson, a researcher at the Nicholas Institute for Environmental Policy Solutions who authored a study earlier this year on oil and gas spills (Greenwire, Feb. 21). She found that most spills happen in the first three years of a well's life. "If there's fewer new wells, I would expect the number of spills to decrease," Patterson said.

Colorado, Pennsylvania, New Mexico, and North Dakota saw more than 6,600 spills from fracking wells — or more than one spill for every five wells — from 2005 to 2014, according to a study released Wednesday by the Nicholas Institute for Environmental Policy Solutions. The results suggest that the oil and gas industry needs to have stronger, more consistent reporting requirements for spills, which can include oil, chemical-laden water, and other substances, researchers said. “As this form of energy production increases, state efforts to reduce spill risk could benefit from making data more uniform and accessible to better provide stakeholders with important information on where to target efforts for locating and preventing future spills,” lead author Lauren Patterson told ThinkProgress.

Hydraulic fractured oil and gas wells spill pretty often, according to a recent study in the journal Environmental Science & Technology, led by the Nicholas Institute for Environmental Policy Solutions. That study, along with a companion paper which appeared in the journal Science of the Total Environment, analyzed spill data and behavior across four states—Colorado, New Mexico, North Dakota and Pennsylvania—with the goal of identifying common causes of spills to help industries improve, reports Popular Science.

The nation's regulation of oil and gas development is a mish-mash of disjointed state oversight that makes it difficult to quantify the environmental impacts of drilling, reports Inside Climate News. A new study highlights just how inconsistent spill reporting is, showing that the range in requirements makes it impossible to compare states or come up with a comprehensive national picture. The research, published Tuesday in the journal Environmental Science and Technology, pulled together some of the disparate data and found there have been about 5 spills each year for every 100 wells that have been hydraulically fractured. Of the states examined, North Dakota had the highest rate of spills while Colorado companies reported just 11 spills per 1,000 wells annually.

Two papers on unconventional oil and gas development highlight the need for states to develop standardized data collection and reporting requirements for spills to better identify and manage risks for nature and people, reports the Nature Conservancy's Cool Green Science blog. “State spill data holds great promise for risk identification and mitigation. However, reporting requirements differ across states, requiring considerable effort to make the data usable for analysis,” said Lauren Patterson, policy associate at Duke University’s Nicholas Institute for Environmental Policy Solutions and the study’s lead author. “Given the rapid recent development of unconventional oil and gas development, data are scarce on both how often spills happen, what causes them, what materials are spilled, and what the long-term environmental effects are. There is a need to better quantify risk to people and nature.”

New analysis in the journal Environmental Science & Technology finds that 2 to 16 percent of hydraulically fractured oil and gas wells across Colorado, New Mexico, North Dakota and Pennsylvania spill hydrocarbons, chemical-laden water, hydraulic fracturing fluids and other substances each year. It examines state-level spill data to characterize spills associated with unconventional oil and gas development at 31,481 wells hydraulically fractured or "fracked" in the four states between 2005 and 2014, identifying 6,648 spills in the 10-year period. Authors conclude that making state spill data more uniform and accessible could provide stakeholders with important information on where to target efforts for locating and preventing future spills. However, reporting requirements differ across states, requiring considerable effort to make the data usable for analysis.

Each year, 2 to 16 percent of hydraulically fractured oil and gas wells spill hydrocarbons, chemical-laden water, hydraulic fracturing fluids and other substances, according to a new study.The analysis, which appears Feb. 21 in Environmental Science & Technology, identified 6,648 spills reported across Colorado, New Mexico, North Dakota and Pennsylvania during a 10-year period. "This study provides important insights into the frequency, volume, and cause of spills," said Lauren Patterson, policy associate at Duke University's Nicholas Institute for Environmental Policy Solutions and the study's lead author.

Up to 16% of hydraulically fractured oil and gas wells spill liquids every year, according to new research from U.S. scientists BBC News reports. The Nicholas Institute for Environmental Policy Solutions led study published in Environmental Science & Technology, found that there had been 6,600 releases from these fracked wells over a ten-year period in four states.

A new study investigating spills from hydraulically fractured oil and gas uncovered 6,648 spills in just four states over a ten-year period. Part of the SNAP Partnership, the study examined data from Colorado, New Mexico, North Dakota, and Pennsylvania. Significant differences in reporting requirements across states made this analysis difficult, according to a report by ResearchGate.

If there's an enduring upside to U.S. Environmental Protection Agency's doomed Clean Power Plan, ClimateWire reports, it's that it spurred some much-needed discussions about energy on the state level. "There really was not much going on in terms of coordination and dialogue between energy and environmental regulators at the state level before all this," said Brian Murray, director of the Environmental Economics Program at Duke University's Nicholas Institute for Environmental Policy Solutions. But since the Clean Power Plan was proposed in 2014, Murray said, there has been an "improved understanding of how the power sector works by environmental regulators."
