Background, continued

Since OOC’s initial citation in December 2000, AOC has reported taking some actions to address some of the problems in the tunnels, including the following:

In 2001, AOC contracted with the Federal Occupational Health (FOH) to assess the condition of asbestos in the entire CPP, including the tunnels. FOH found that the asbestos in the tunnels was generally in good condition—that is, it was not damaged or exposed.

In 2004, AOC replaced 600 feet of the roof in one tunnel in response to the 2000 contractor’s report on tunnel conditions.

In 2004, AOC began another project to upgrade 15 tunnel entry and exit points.

In 2005, AOC removed asbestos from one of the tunnels.

In addition, since 1999, AOC’s Construction Management Division has been working to identify and remove developing spalls and has recently increased its efforts to identify and remove any spalling concrete.
