Some measures promoting or establishing bans in other jurisdictions expired or were avoided in 2011. The efforts of USGS and local activists to promote bans has continued, with more science articles using the discredited USGS model as the basis for continued claims that refined tar-based sealer is a significant source of PAHs. And PCTC is continuing to push back. While continuing to study refined tar-based sealer in the environment, it’s clear that scientific studies and publications – while essential to the debate – must be supplemented with action and challenges to misinformation.
Refined tar-based sealer manufacturers and users at all levels must be aware and become involved. Watch and listen for developments that might impact refined tar-based sealer in your communities. Let PCTC know, talk with your elected representatives, get involved. Your involvement is key!
