chemicals and 571 orphan chemicals, 352 chemicals
that would otherwise have been included in the
Program are not considered within the scope of
the HPV Challenge Program. The following table
provides a detailed description of these chemicals that
are considered outside the scope of the Program for
the reasons described in the previous section.
The figure below illustrates the progress of chemical
sponsorship in the Program.

have been made, some are sponsored through the HPV
Challenge Program and some are sponsored through
the ICCA HPV Initiative. Note that 123 chemicals
are sponsored both in the HPV Challenge Program
and through the ICCA HPV Initiative (see the figure
below).

The sponsor of a chemical may or may not be the same
in both programs. Additionally, a sponsor may have
chosen to work through only one program, but has
not officially informed EPA that the dual sponsorship
status has changed. Until EPA is notified in writing
by the sponsor stating that sponsorship has changed
from one program to another, records will continue to
show the chemical as sponsored under both programs.
