On the eve of Earth Day, clean air group Downwinders at Risk announced the purchase of two portable, EPA-calibrated ozone monitors to initiate a citizen-based monitoring campaign in Wise County this summer, where state officials refuse to measure DFW smog. “With the purchase of these brand new high-tech monitors, which reached the market only a few months ago, we […]

Somewhere deep in the cubicled bowels of the Region 6 EPA offices in downtown Dallas lies a draft of a letter to the State of Texas telling Austin it’s proposed clean air plan for DFW is inadequate and must be re-written. It likely goes through the litany of well-known public objections the EPA has about the […]

Holcim is the first cement plant in the nation to voluntarily install an industrial catalytic converter called SCR on its smokestack, significantly cutting smog-forming air pollution in DFW.  But despite operating only 26 miles from EPA headquarters, the Agency and State of Texas still claim the technology isn't "feasible"     Downwinders is proud to announce Midlothian's Holcim […]

State Representative Chris Turner, whose District 101 spans west Grand Prairie and east Arlington between Dallas and Fort Worth became the first state elected official to urge EPA to reject the current state anti-smog plan for DFW and substitute one of its own.  In a letter to EPA Chief Gina McCarthy, Turner used language echoing the sentiments of US […]

Yesterday was the single worst day for DFW smog in the last three years. Seven monitoring sites stretching from central Dallas to Weatherford saw hourly averages of 90+ parts per billion. Three sites in Arlington, Northwest Fort Worth and Keller saw levels reach 100 + ppb. Two of those sites saw hourly levels climb to 113 ppb. […]

Small stuff adds up. Thousands of gas wells, pipelines, storage tanks, compressors, and other pieces of infrastructure in oil and gas patches, which individually don't emit the huge volumes of air pollution coming from a single cement kiln or a coal plant can, when combined, easily total tonnage larger than both.  And that's what has happened in DFW over […]

There was a lot of coverage of last week's announcment of a new, more protective national smog standard by EPA. Most of it centered on the reaction by both sides that it was either not enough progress (public health advocates), or Western Civilization was about to collapse under the weight of all the controls necessary […]

EPA has released the results of the first test of a full-scale Selective Catalytic Reduction (SCR) unit on a US cement plant and the numbers look good. As many of you know, SCR is just an industrial-sized version of the catalytic converter in your car. It can capture up to 90% or more of the […]

State officials and industry PR types thought they'd caught a break last summer when two things produced a much lower annual smog average, called a "Design Value."  Since it's a three-year rolling average of smog numbers, past years roll off as new ones come on. Smog numbers from 2011 that had been so high they'd […]

By this point, most of you will have been inundated with opinions and factoids about what President Obama's new "Clean Power Plan" will and won't do about climate change. Bottom Line: while it sets a precedent and an emissions floor for the largest sources of CO2, it does so in a way which turns out […]

Mercifully, the 2015 Texas Legislative Session is almost over. Since January we've seen cities stripped of their traditional zoning power over oil and gas facilities, citizens' ability to challenge new pollution permits further suppressed, and renewable energy sources singled-out for financial punishment. But the circus leaves town on June 1, and shortly after that Downwinders […]

When environmental health advocates speak about the dangers of dirty air, the effects are often categorized as long term and cumulative. But the more scientists delve into the subtleties of the human body and what outside influences can do it, the more they realize that even short term exposures can be harmful. That's been especially […]

Study: Less Smog Means Healthier Kids

by jim on March 5, 2015

Up to this point almost all studies about air pollution have tracked increasing levels of air pollution with decreasing levels of health. Respiratory problems, strokes, heart disease, Autism, Parkinson's-like symptoms – they've all been linked to exposure to high levels of air pollution vs exposure to less severe air pollution. Now, comes a new study […]

There was at least one truth uttered by Steve Everley, the professional PR spokesperson for Energy in Depth, itself the PR arm of the Gas Industry, during his testimony at last Thursday's EPA ozone standard hearing in Arlington: "…natural gas producers will be significantly impacted by EPA’s proposal to reduce the National Ambient Air Quality […]
