Hundreds of Dallas County industrial sites pose a hidden risk to …

The accordion notes of a Tejano song rollick from a window through the breezeways and over the community pool. Around the corner, men grill corn and fajitas. An ice cream vendor rings his bell, and children come running. The residents of the Regal Villas apartments north of Bachman Lake go about their lives, unaware of the danger nearby.
Separated by only a ditch and a chain-link fence, workers at the Petra Chemical Co. drain chlorine from a 90-ton rail tanker to make bleach. The workers perform a perilous task. If the chlorine leaks, a yellowish-green fog could creep through the Regal Villas. It could burn eyes, blister skin and suffocate anyone in its path.
In the company’s worst-case scenario filed with the Environmental Protection Agency, particles of chlorine could spread 14 miles from the plant – as far away as Plano, Grapevine or Garland. About 2.3 million people could be in the danger zone. As many as 17,500 could die.
It’s a risk repeated throughout Dallas County, from ramshackle bungalows in South Dallas, to half-million-dollar homes in Richardson, to new lofts along the Trinity River.
Thousands of Dallas County residents are at risk of a toxic disaster because outdated and haphazard zoning has allowed homes, apartments and schools to be built within blocks – in some cases even across the street – from sites that use dangerous chemicals.
A Dallas Morning News investigation found dozens of sites that are more toxic and closer to residential neighborhoods than the acetylene gas plant that exploded near downtown last summer.
That blast produced massive fireballs and a column of black smoke. Flaming gas cylinders rained on morning traffic. One launched a quarter-mile, sailing over 12 lanes of the Mixmaster and leaving a basketball-size hole in the black glass of Reunion Arena. Buildings a mile away rumbled. Those fleeing felt the heat on their backs. No one died, but the blaze injured three people, including one who suffered third-degree burns.
