Critical Decision Expected Tomorrow in Colorado on Clean Air Rule

Day 4 of the ongoing hearings on a groundbreaking proposal to reduce air and climate pollution from oil and gas operations in Colorado saw Team EDF pushing back on claims opposition groups have made to try to weaken the proposal.

Leading companies Noble, Anadarko, Encana and DCP also put on strong cases, using their own operational data to show the proposal is cost effective. They should be lauded for their leadership, as should local governments and conservation groups that brought strong analytics to the hearings.

If the proposal is adopted without being weakened, it will eliminate more than 90,000 tons of smog-forming VOCs annually (the same amount produced by all the cars and trucks in Colorado) and more than 100,000 tons of methane, a highly potent greenhouse gas.

COGA and CPA Fight Common-sense Methane Regulation

Dan GrossmanIndustry trade groups – the Colorado Oil and Gas Association (COGA) and the Colorado Petroleum Association (CPA) – came out swinging against methane regulation in the third day of hearings on a groundbreaking proposal to reduce air and climate pollution coming from oil and gas operations.

And some wild swinging it was!

They acknowledged that we need to reduce methane, a highly potent greenhouse gas. But they said studies are showing different results about how much methane is being leaked and vented and that we shouldn’t regulate methane until we know exactly how much is escaping.

Arguments Heat Up in Colorado Air Rulemaking, But the Facts Remain

Yesterday, we covered the Colorado Air Quality Control Commission (AQCC) taking public testimony from citizens who traveled from around the state to speak in support of a groundbreaking proposal that would slash emissions of smog-forming pollutants and greenhouse gases coming from oil and gas activities.

Formal proceedings kicked off today – and will likely run through the weekend – with various parties presenting their opening cases. EDF went early in the day, providing strong evidence that the proposed rule is cost-effective and urgently needed to combat local air quality problems and climate change. We also highlighted some glaring flaws  in the methodology industry opponents cooked up to show inflated costs for the rules.

The Colorado Oil and Gas Association (COGA), the Colorado Petroleum Association (CPA) and the DGS group are throwing everything they can at the rule to try to gut it.  But they’re in a shrinking minority on the wrong side of history.

Coloradans Overwhelmingly Voice Support for Proposed Air Regulations

Colorado is the quintessential swing state – with voters split about evenly between Republicans, Democrats and Independents.  That can make for some fractious politics at times, but our diversity is part of what makes us great.

What makes us even better is our unity – and that’s what we saw today when, by a margin of almost 10-to-1, Coloradans of all stripes called on the state’s Air Quality Control Commission (AQCC) to adopt new rules that would slash air and climate pollution coming from oil and gas development activities.

The AQCC opened its hearings on the proposed rules with a full day of citizen input, with people traveling from around the state (one drove six hours) to make their voices heard.  Residents from rural communities, including many from the Western Slope, stood up, one after another, to tell the AQCC Commissioners that the proposed rules should apply statewide and that the handful of local officials opposing the rules are out of step with the citizens they’re supposed to serve.  In response to those local officials, one citizen from Ridgway implored the Commission to protect all Colorado families and not “turn the West Slope into an air quality sacrifice zone.”

EDF couldn’t agree more.  Air quality in western parts of Colorado is trending in a bad direction, teetering on the edge of violating federal health standards.  The state health department issued nine ozone advisories last winter for Western Slope counties where oil and gas development is prevalent, meaning the air wasn’t healthy for kids, the elderly, active adults and people with respiratory illness.

Another Major Methane Study Shows Action is Needed Now to Reduce Emissions

Hamburg-228x300This commentary originally appeared on the EDF Voices Blog.

Mounting scientific evidence underscores the crucial importance of reducing methane emissions in the U.S. The latest study, published today in the journal Science, reviewed available data from the past 20 years and found that methane emissions from the U.S. natural gas supply chain are almost two times greater than current official estimates – flagging once again that methane emissions are a serious problem. However, the Stanford-led team also concluded that the current levels of methane leakage negates the climate benefit of switching to natural gas under some scenarios and not others, such as moving from coal-powered to natural gas electric generation.

As for what contributes to the higher than expected emissions, the study authors cited differing measurement techniques—including “bottom-up” direct measurement at the source, “top-down” readings from aircraft, and others—as well as the presence of “super-emitters” (a small number of sites or pieces of equipment producing a large share of emissions). Super-emitters are not easily sampled using most bottom-up direct measurement approaches. The team also spotlighted challenges associated with an increasingly ambiguous distinction between emissions from natural gas and oil production, both of which contribute methane to the atmosphere.

New Study Underscores Urgent Need to Reduce Methane Emissions from Natural Gas Operations

Steve-Hamburg_D4B8294_287x377You may have seen news reports about a new methane emissions study conducted by climate researchers from Harvard and seven other institutions and just published in Proceedings of the National Academy of Sciences (PNAS).  The new paper provides an improved estimate of the total methane budget of the US – in other words, how much methane is being released into the atmosphere each year from all sources, including livestock and oil-and-gas production.

Based on analysis of nearly 5,000 air samples collected in 2007 and 2008 from ten communications towers located around the country, as well as 7,700 samples taken in those years from an aircraft monitoring program, the study finds that total methane emissions due to human activity were roughly 1.5 times greater at that time than previously estimated.  Emissions from livestock were roughly twice as high as previous estimates.  Emissions from oil-and-gas operations in Oklahoma and Texas were 2.7 times higher than estimated.

We are glad to see the methane issue getting the attention it deserves.  While EDF’s work to deepen our understanding of current emissions continues, there’s no question about the need for regulation to measure and reduce these emissions.  In August, scientists with the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado (UC) at Boulder published a long-awaited paper on methane leakage in the journal Geophysical Research Letters that reported an alarmingly high level of methane emissions in the Uintah Basin of Utah — 6.2 to 11.7 percent of total production for an area about 1,000 square miles.  Read More »
