Colorado: Noble Energy agrees to clean up Front Range fracking pollution

Settlement with EPA, state health department should cut emissions of smog- and cancer-causing toxic gases

Staff Report

FRISCO — For years, thousands of storage tanks owned and operated by Houston-based Noble Energy leaked toxic smog- and cancer-causing gases into the Colorado’s heavily fracked Front Range.

When when state and federal environmental inspectors confronted the company with evidence of the leaks, executives shrugged, and said their systems weren’t designed to handle the sudden oil and gas boom across the region. Continue reading

Colorado GOP launches preemptive strike on EPA’s Clean Power Plan

Clean Power Plan under attack in Colorado.

Proposed bill up for a committee hearing today

By Bob Berwyn

FRISCO — Backed by the fossil fuel industry, Republican Colorado lawmakers are launching a preemptive effort to block or delay the state from implementing the EPA’s Clean Power Plan, aimed at reducing emissions from power plants. The plan has not been finalized yet, but that apparently won’t stop the misguided effort in the Colorado Senate.

Senate Bill 15-258, misnamed as the “Colorado Electric Consumer’s Protection Act.” would require the state to undertake burdensome and costly reviews of any Clean Power Plan rules adopted by the Colorado Department of Public Health and Environment’s Air Quality Control Division — including a full evidentiary hearing before the Public Utilities Commission to evaluate impacts to electricity rates.

Staff Report

FRISCO — A recent study of satellite data showing a hotspot of potent heat-trapping methane pollution over the Four Corners region makes it clear that we’re digging an ever-deeper global warming hole by fracking every last corner of the country.

As NOAA put it, “Vast regions west of the Mississippi River are under development for oil and gas extraction … but while one focus is on what comes out of the ground, NOAA and Cooperative Institute for Research in Environmental Sciences researchers and their colleagues are studying what escapes to the air—and how it is transformed in the atmosphere and affects air quality and climate.

Scientists hope to learn much more about the massive quantities of pollution escaping from fossil fuel development areas in the next few months as they launch this year’s  Shale Oil and Natural Gas Nexus (SONGNEX 2015) field campaign, using airborne instruments to measure greenhouse gases and other toxic emissions.

Study links climate change and pollution with growing allergy epidemic

Staff Report

FRISCO — Global warming has already been implicated in the rising tide of allergies, simply because a warmer climate extends the growing season for many plants, or causes them to produce more pollen.

But there’s more to it, according to scientists, who say that a pair of air pollutants linked to climate change could also be a major contributor to the unparalleled rise in the number of people sneezing, sniffling and wheezing during allergy season. Continue reading

Report shows huge benefits of pursuing wind energy

Clean energy saves lives and money in the long run, reduces water demand from power sector

Staff Report

FRISCO — Boosting the role of wind power in the country’s energy portfolio would have significant economic, environmental and health benefits, the Department of Energy found in a new report that outlines the  path needed to achieve 10 percent wind by 2020, 20 percent by 2030, and 35 by 2050.

Currently, wind power generates about 4.5 percent of the country’s energy. Reaching the 2050 goal would reduce cumulative greenhouse gas emissions by 14 percent, saving $400 billion in avoided global damages, the report found. Continue reading

When will planners start considering the public health impacts of urban traffic congestion?

New traffic pollution data screams out for better transit planning and improved emissions control technology for motor vehicles

Staff Report

FRISCO — Pollution from auto exhaust can quickly build to dangerous levels at stoplights, where drivers are exposed to about 25 percent of their total exposure during a typical commute.

More and more research is proving that the nanoparticles from exhaust contribute significantly to respiratory and heart disease, so University of Surrey scientists decided to study the exposure. Drivers spend just 2 percent of their journey time passing through traffic intersections managed by lights, this short duration contributes to about 25 percent of total exposure to these harmful particles.

Signalized traffic intersections were found to be high pollution hot-spots due to the frequent changes in driving conditions. With drivers decelerating and stopping at lights, then revving up to move quickly when lights go green, peak particle concentration was found to be 29 times higher than that during free flowing traffic conditions.

Environment: Study finds air pollution-autism links

New environmental justice deal signifies progress, experts say.

Exposure to fine particulate air pollution during late pregnancy increases risk of autism.

Findings could open the door for preventive measures

Staff Report

FRISCO — Harvard public health researchers say evidence is growing that exposure to high levels of air pollution during pregnancy may double the risk of having a child with autism. The study was the first to explore the link between airborne particulate matter and autism. Continue reading
