The Secretary shall establish two priority lists for regulating potential occupational carcinogens. One list should include approximately
ten (10) candidates for rulemaking as Category I Potential Carcinogens; the other approximately ten (10) candidates for rulemaking as Category II
Potential Carcinogens. The order of placement of substances on these lists will not reflect the Secretary's determination of the exact order in which
these substances should be regulated in rulemaking proceedings but rather a policy determination that the Secretary plans to address some or all of
these substances prior to proceeding with a thorough scientific review of data concerning other substances on the Candidate List. The inclusion or
exclusion of any substance on these lists shall not be subject to judicial review or be the basis for any legal action. The Secretary may regulate a
potential occupational carcinogen which has not been placed on these lists. The inclusion of a substance on either of these lists does not reflect a
final scientific determination that the substance is, in fact, a Category I Potential Carcinogen or a Category II Potential Carcinogen.
EFFECTIVE DATE NOTE: Section 1990.131 was stayed at 48 FR 243, Jan. 4,
1983, in order to evaluate the impact of publishing the Candidate List
and Priority Lists and to reconsider the criteria used in establishing
the lists (see also 47 FR 187, Jan. 5, 1982).
