Emails obtained through a Minnesota-version of the a Freedom of Information Act (FOIA) request tell the story of how the Minnesota Pollution Control Agency pushed through a statewide ban on refined coal tar-based pavement sealers (RTS) using a mix bad science, unnecessarily burdensome regulation, misspent taxpayer dollars, and politicians led by federal and state employees with misguided policy preferences. In a multi-part series published in Pavement Maintenance & Reconstruction magazine, the emails tell the tale. Part 1 was published in March 2014 issue. Part 2 in May 2014. Part 3 was published in June 2014.
