Cameras reveal Ship Channel's tanks and barges as hidden sources

Smog-forming, and possibly toxic, pollution is leaking from nearly 200 previously undocumented locations along Texas' industrial corridors, new state data show.
Using infrared technology, the Texas Commission on Environmental Quality study unearthed new pollution sources, decades after efforts to clean up smog began, that may need to be controlled for Houston and other industrial areas of Texas to meet health-based standards for ground-level ozone.
The state research found 175 previously invisible leaks coming from barges, flares, storage tanks and other industrial equipment along the Houston Ship Channel and in Texas City, Beaumont and Port Arthur.
Only recently has infrared technology — the same technology that enables soldiers to see at night — been used to document pollution. However, it is unable to measure the quantity or detect the specific chemical released.
"It opens a new window in the way we do our business. We keep regulating the same people a little tighter. We never had the opportunity to see who else was out there that we were missing," said TCEQ Commissioner Ralph Marquez of the $100,000 research project, part of broader series of Texas air quality studies due to be completed in October 2006.
Previous research has shown that Ship Channel companies are underestimating the quantity of emissions, particularly a group of chemicals called volatile organic compounds, coming from their plants. Several highly reactive volatile organic compounds, combined with nitrogen oxides, form ground-level ozone, the main ingredient in smog.

"We knew they were in the air, but we did not know where they were coming from," said Marquez. "This accounts for all or more of the under-reported or unrecognized emissions."

Well we know its there NOW if we DO something about it!!! Not Likely!!!
