for Listing in or Delisting (Removing) From the Report on Carcinogens, 
Tenth Edition; Amendments

action: Notice; Amendments.

-----------------------------------------------------------------------

summary: The NTP published in the Federal Register of April 2, 1999, a 
list of substances to be reviewed for possible listing in or delisting 
from the Report on Carcinogens, Tenth Edition. The notice is being 
amended to (1) extend the deadline for public comment period to June 3, 
1999 and (2) to expand the section on ``Clarification of the

[[Page 19189]]

Criteria'' to address some misunderstandings regarding the application 
of the final paragraph of the criteria for listing agents, substances 
of mixtures in the Report on Carcinogens.

amendments: In the Federal Register of April 2, 1999, in FR Doc. 99-
8098, on page 15984, in the fist column under the section ``Public 
Comment Requested'' the 8th line with the sentence starting ``Comments 
received by April 30, 1999 * * *'' and the rest of the section is being 
deleted and the following added: ``Comments received by June 3, 1999 
will be considered by the review groups in the preparation of the 
background documents for each substance. Comments or questions should 
be directed to Dr. C.W. Jameson at the address listed below.''
    In the section ``Clarification of the Criteria'' on page 15983, in 
the third column, a second paragraph is added as follows: There have 
also been some misunderstandings regarding the application of the final 
paragraph of the criteria which begins, ``Conclusions regarding 
carcinogenicity in humans or experimental animals * * *'' Since these 
criteria were first published on September 26, 1998 (61 FR 50499), the 
paragraph has applied to both the ``known to be human carcinogen'' and 
the ``reasonably anticipated to be human carcinogen'' categories and 
will continue to apply.
