THE ASTRODOME’S FIRST SOLUTION TO ITS CAN’T-SEE-THE-BALL PROBLEM Before players had that problem losing fly balls in the glare, before a portion of the skylights were painted over, before anyone in Houston had ever considered replacing the outfield grass with something called AstroTurf, there was another system installed in the Astrodome meant to help baseball players keep their eyes on the ball. The Houston Chronicle‘s special section on the Harris County Domed Stadium — on the occasion of its 50th anniversary (today) and birthday party open house (tonight) — includes a reprint (PDF) of the same newspaper’s Astrodome extra from April 8, 1965, the day before opening day. And featured on page 62 is a short preview of the stadium’s space-age air-cleaning technology: “An unusual Honeywell-engineered ultraviolet sensor will run a continual check on the transparency of the air. If it gets murky — from dust or tobacco smoke — the system will signal stadium engineers to open a battery of cupola exhaust dampers.
Because air cleaners continuously scrub the air electronically, then pass it through special charcoal filters to sieve out any odors, air inside the stadium normally will be fresher and cleaner than the air outside. ‘In fact, it should be the cleanest air in all Texas,‘ says Lamar Bordelon, Honeywell project engineer on the stadium job.
The Honeywell system has an ultraviolet lamp underneath the seats along the third-base line, focused on an ultraviolet sensor in similar position along the first-base line, 700 feet across the stadium. These continuously indicate the transparency of the air between them on a meter located on the control center. Any time the transparency of the air drops to the point where a player would have a hard time seeing a baseball in play 350 feet away, a warning light flashes on.” [Houston Chronicle] Photo: Russell Hancock
COMMENT OF THE DAY: FOLLOW THE SMOG “You do not escape smog in Houston by moving to the burbs. In the summer, Houston has a circular wind pattern that takes ship channel pollutants for a ride out to the suburbs. Go to the Houston Clean Air Network website and set the animation for Aug. 6, 2012. You will see a big area of ozone form over the ship channel that gets blown out to Pearland, then Sugar Land and spends the late afternoon in Cinco Ranch and just east of Katy before starting to drift back east. The worst of the smog slides south of the City and never really gets north of I-10 inside the loop. Ship channel industries account for about 2/3rds of the smog. The rest is motor vehicle emissions. Ship channel industries have made significant progress in reducing and controlling emissions. But more sprawl and more traffic threaten to offset the progress made on the ship channel. Thus, the smog issue is a very real consequence of sprawl that is not escaped by sprawl either.” [Old School, commenting on Holding Back on That Downtown Hotel Push; The Beer Garden, Greenhouse, and Food Court Growing in Prohibition’s Basement] Image: Houston Clean Air Network
How do you feel about Houston’s airborne cancer hotspots? That’s easy! Just pick up a copy of the latest issue of Cite magazine and run your fingers over the top of it: Cite 93‘s front cover has been embossed with a map diagramming the area’s cancer risk. The places where airborne toxins mapped by the EPA are most prevalent are in the pits.
The mapped information here isn’t exactly fresh — it’s from the 2005 National-Scale Air Toxics Assessment, and the data only account for airborne known-cancer-causing toxins that are tracked by the EPA. Though it’s posted online, the map version isn’t exactly easy to find. But bravely thumbing his nose at Houston’s proud and longstanding tradition of hush-hushing location-based cancer hazards, Cite editor Raj Mankad gives Swamplot readers the secret recipe for finding the browsable map:
COMMENT OF THE DAY: WHAT’S IN YOUR AIR “There are three big air quality concerns for Houstonians: toxics, smog and particulates. Living in the East End puts you on the front line for toxic emissions. Toxics tend to be heavier than air and do not travel very far from where they are released. Milby Park had almost off the chart levels of Butadiene 1,3 back in mid 2000 due to problems at the Texas Petrochem plant next door. That problem was fixed and levels have come way down. But, if there is a release or a leak that is sending off toxics, the East End gets the best whiff. On days where there is little wind, the East End is also the spot most likely to get smog (NOx+SOx+sun=ozone). If there is good circulation in the atmosphere, Pearland to Sugar Land can see pretty bad smog, especially with the old coal plant in Sugar Land. But so can everywhere from Memorial Park up to the Woodlands. Houston’s smog has improved dramatically thanks to some good work by regulators and industry in identifying and going after the highly reactive stuff that really drives ozone production. But Houston is still in the top ten nationally when it comes to ozone. . . . Particulates are not as big a concern in Houston as we do not have much steel or other industries that are heavy on particulates, but we are still just over the new Federal standard of 12 parts per somethingerother. The particulates on the East End are generally higher than in other parts of town due to all the industry in the area. The air quality on the east side is definitely worse than on the west side. But ozone (smog) can visit just about anyone in the Houston area.” [Old School, commenting on Comment of the Day: The Limits of Eastward Development] Illustration: Lulu
COMMENT OF THE DAY: OH, AND WATCH OUT FOR THOSE AREAS NEAR THE SHIP CHANNEL TOO “If you are looking inside the loop at places like Eastwood or just outside the loop at places like Oak Ridge and Westbury, be careful that your house is at least 1000 feet from any highways. Living within 1000 feet of a major highway can expose your children to serious air quality issues in addition to what we already have to endure in Houston. Also, make sure that you get the house tested for lead paint and be ready to have some cash on hand to do some work to remediate any lead paint on the interior and any lead paint that is coming off on the exterior. I always thought that I was being overly cautious when I had my house remediated before moving in. But one day I had my then 4 month old baby on the changing table and watched as he scratched the paint on the wall with his finger and then put his finger in his mouth . . .” [Old School, commenting on Crazy for the Inner Loop]
HISD has now contracted with an industrial hygienist to evaluate the drainage systems, mechanical rooms, and plumbing and electrical systems at Barnett Stadium in an attempt to determine what might have caused 22 band or dance-team members from Stephen F. Austin High School to become mysteriously ill during a football game there Friday night. Several students displayed what appeared to be symptoms of carbon monoxide poisoning. Epidemiologists have been interviewing students and school officials “to get information on the whereabouts of the band members within the stadium and collect other health related-factors that could have played a role in the event,” the school district announced. The HISD Athletics Department is expected to announce tomorrow morning whether 2 UIL playoff games scheduled for this week at the 6800 Fairway Dr. location will be moved to a different field.
COMMENT OF THE DAY: WESTERN AIR “. . . in cities old enough to predate water systems it was common for the favored side to grow upstream. Even after city sanitation, flood control, and car ownership that makes it possible to live ‘way up a hill without having to have the leisure to live so far from things – and even where that legacy doesn’t hold over in property investment – air quality is generally better higher up, nevermind views: so that in North America, where our water often flows to the east and south, even newer cities often favor west and north. Especially north. Nashville, Monterrey, East Bay, Memphis, and others where the east or south is higher ground, or cities where race riots took place after city sanitation came around, prove the rule by suggesting how much it takes to buck it and confirming why. Think about it and see why else you can come up with!” [Austin, commenting on Comment of the Day: The Common Divide]
A new study from the National Center for Atmospheric Research documents how Houston’s vast expanse of paved surfaces allows the city to hold onto locally developed air pollution for longer periods of time, and prevents breezes that would otherwise naturally develop from sending all that nasty smog and stuff to outlying areas. Concrete and asphalt paving helps by soaking up heat during the daytime. This keeps land areas relatively warm overnight, which means there’s a lower contrast between land and sea temperatures during the summer. The result? Much less of those smog-stealing nighttime summer breezes. During the daytime, Houston buildings help to block local winds and keep things more still in the afternoon. Just another way standard development practices allow Houston to be a responsible steward of its own locally produced airborne products.

RAINY DAYS AND SUNDAYS ALWAYS GET ME DOWN “So it stinks like something awful again where I am today (the Heights). I look at the calendar and realize it’s been 2 prime dump days in a row, a wet Sunday followed by a national holiday. An old friend of mine who grew up on the east side used to say that a Sunday when it rained was the perfect day for all the refineries to release their nastiest emissions, because the rain masked it and for some reason there wasn’t any enforcement on the weekend. I’m wondering where else in the city it smells like what I’m smelling, and is there any truth to the rainy-day-dump theory? That’s some strong anecdotal evidence in my nostrils.” [Swamplot inbox]
