Protection Agency on the day before the date of the 
enactment of this section). 
‘‘(2) RELEVANT PROGRAM OFFICE.—The term

STEERING COMMITTEE. 
‘‘(a) ESTABLISHMENT.—Not later than 30 days after 
the date of the enactment of the Improving Science in 
Chemical Assessments Act, the Administrator of the Envi-
ronmental Protection Agency shall establish a chemical 
hazard identification and dose-response steering com-
mittee (referred to in this section as the ‘steering com-
mittee’) to coordinate the conduct of covered assessments 
by relevant program offices for purposes of ensuring that, 
with respect to such assessments, there is no duplication 
of effort by such offices. 
‘‘(b) DUTY.—The duties of the steering committee 
are the following: 
‘‘(1) If the steering committee learns that more 
than one relevant program office intends to conduct 
covered assessments with respect to the same chem-
ical substance, the steering committee shall deter-
mine the most effective means of carrying out a sin-
gle covered assessment to prevent duplication of ef-
fort by such offices. 
‘‘(2) For purposes of supplementing a covered 
assessment, the steering committee shall consider 
any third-party assessment of a chemical substance 
generated by another Federal, State, or inter-
national agency or agencies or members of the sci-

‘‘(3) reflects the best available science and the 
weight of the available scientific evidence. 
‘‘SEC. 7B. SCIENTIFIC STANDARDS. 
‘‘Covered assessments carried out under section 7 
and discussion of such assessments and review of third- 
party assessments carried out under section 7A shall be 
conducted using scientific information, technical proce-
dures, measures, methods, protocols, methodologies, or 
models in a manner consistent with the best available 
science. In carrying out such an assessment, the relevant 
program office shall integrate all lines of scientific evi-
dence and consider, as applicable, the following: 
‘‘(1) The extent to which the scientific informa-
tion, technical procedures, measures, methods, proto-
cols, methodologies, or models employed to generate 
the scientific information are reasonable for and con-
sistent with the intended use of the scientific infor-
mation. 
‘‘(2) The extent to which the scientific informa-
tion is relevant for the relevant program office’s use 
in making a decision regarding a chemical sub-
stance.
