Reader’s Guide to the DDVP Docket # OPP-2002-0302

Publication Date: December 5, 2007

EPA has created this document to provide an organizational structure to
the latest entries to the DDVP docket.  The Agency is providing the
“Readers Guide” for DDVP to allow the reader to more easily access
and navigate the various entries contained in the docket.  These entries
include EPA’s responses to the petition dated June 2, 2006 submitted
by the Natural Resources Defense Council (NRDC) and the documents
supporting the petition responses.  One petition response document
addresses the petition request to have EPA revoke all tolerances for
DDVP and the other response document addresses the petition request to
have EPA cancel all registrations for DDVP.  (Taken together, these 2
response documents form EPA’s response to the petition.)  In the case
where a document was used to support both EPA response documents, the
support document was entered into docket EPA-HQ-OPP-2002-0302 one time. 
If a support document was already available in the docket, it was not
added again.  All materials have also been added to the DDVP Special
Review docket (EPA-HQ-OPP-2006-0396).
