CEMEX Violates Clean Air Laws Again

The CEMEX cement plant in Lyons, Colorado has violated clean air laws again, putting clean air and public health at risk again, and once again proving that the company couldn't operate a cement plant responsibly if it tried.

Last week, the State of Colorado put CEMEX on notice of a multitude of clean air violations and even issued a press release over the action. It's a sign that the state may be waking up to the fact the Lyons cement plant poses a serious risk to clean air and public health in north Boulder County. Late last year, the state gave CEMEX the green light to keep violating clean air laws, a move that Rocky Mountain Clean Air Action has challenged. The latest notice issued to CEMEX is a refreshing change in direction from the state.

But these recent violations are merely the latest in a long history of violations. Since 2000, CEMEX has been cited by the State of Colorado six times for violating clean air laws. Last year, both Rocky Mountain Clean Air Action and the U.S. Environmental Protection Agency put CEMEX on notice of the most serious clean air violations--failing to install the best air pollution controls.

And as if CEMEX's track record wasn't bad enough, yesterday the company reported that a coal silo at its Lyons cement plant "spontaneously" caught fire. The fire, which smoldered for hours on end, spewed coal smoke into the air totally unchecked. We seriously doubt whether the fire was "spontaneous," and it's telling that of this morning, CEMEX had yet to file a required report with the State of Colorado verifying the cause of the fire. The picture below, taken by CEMEX neighbor Ken Dobbs, shows the coal fire.

SUV Driver Upset With Tailpipe Pollution Limits

Earlier this year, tailpipe pollution limits in the Denver metro area were tightened to help safeguard public health from ozone pollution and that has one SUV driver upset. Apparently, his 2001 Land Rover Discovery continues to fail emission tests.

If true, this is a bit of a surprise. For one thing, newer cars typically meet tailpipe pollution limits easily. For another, state health officials have made it clear the only vehicles that will fail are those that are truly broken and need fixed.

Could it be that newer SUVs, or in particular Land Rovers, simply aren't designed to meet tougher pollution limits?

Regardless, we support the new tailpipe pollution limits. With ozone already reaching unhealthy levels in the Denver metro area, we need to do all we can to keep the air clean and safe.

Ozone Season Kicks Off With High Ozone

It's going to be a tough summer for our health.

Last Sunday, June 1st, kicked off the "ozone season," meaning state and local health officials are going to start issuing alerts whenever ozone pollution reaches unhealthy highs. Ozone, a corrosive gas, forms when air pollution from smokestacks and tailpipes react with sunlight.

The timing was a bit late. On May 31st, ozone levels in the Denver metro area soared above the current health standard, which limits ozone to no more than 75 parts per billion over an eight hour period. Last Saturday, ozone levels reached 79 parts per billion at Rocky Flats and 77 in Boulder.

Not only that, but on May 24th and 25th, ozone reached unhealthy highs in Colorado Springs. This was all before the start of the official "ozone season."

These high ozone levels aren't surprising. The U.S. Environmental Protection Agency recently adopted stronger standards limiting ozone to keep communities nationwide healthy and safe, although these standards fell short of what was recommended by the agency's own science advisers.

While we're not surprised though, we're not pessimistic. Sure, we agree with state health official that we're in for a challenge, but this a challenge we can meet. The Regional Air Quality Council itself has recognized this. They've set a goal of meeting the EPA's new ozone standard of 75 parts per billion, an unprecedented step forward since states aren't even required to meet the new standards until after 2011.

But the challenge will be easier to meet than we think. There are a number of strategies to reduce ozone that have yet to be adopted, including stronger limits on pollution from oil and gas drilling, lower volatility gasoline, and cuts in pollution from the smokestacks of coal-fired power plants. These strategies and many more are detailed in The Path Forward, a report prepared by a coalition of environmental groups and local governments detailing the many cost-effective ways to reduce ozone in the Denver metro area.

With high ozone kicking off the ozone season, it's time to aggressively meet the challenge of safeguarding public health. It may be tough to meet stronger ozone standards, but compared to the difficulty of breathing polluted, unhealthy air, it'll be easier than we think.
