Council to Vote on Coal Tar Sealants

San Antonio may soon have a ban on Coal Tar Sealants.

The city council votes this week on the potential ban.

“Coal Tar Sealants, the kind that are used on pavements, roadways, parking lots mainly, have very high concentrations of PAH,” Councilman Ron Nirenberg said. “Those are chemicals that are carcinogenic, they’re known toxins, and they’re very damaging to human health.”

Nirenberg has been outspoken against the sealants.

“They’re picked up on tire dust (off roads and parking lots) and they flow into our storm water and contaminate our water supply,” he said.

Coal Tar Sealants are already banned elsewhere, he said, and the industry has limited the use of it already.

The city council votes Thursday.
