Update: EPA is announcing an extension of the public comment period from the October 21 deadline to November 21, 2013 [Federal Register Notice Oct 24, 2013]. Because of this, EPA will move benzo[a]pyrene (BaP) to the discussion at the December Bimonthly IRIS public meeting (scheduled for December 12-13, 2013). Information on these meetings, including location, time, registration, and meeting materials will be available on the IRIS public meeting page.
Additionally, we recently observed that Figure 1-6 was missing some text, on page 1-69 (see errata sheet for full description). The lost text (“proliferation of initiated cells”) has been restored to the figure.
