Section 8(d) of the Toxic Substances
Control Act (TSCA) and 40 CFR part 716 require manufacturers and
processors of chemicals to submit lists and copies of health and
safety studies relating to the health and/or environmental effects
of certain chemical substances and mixtures. In order to comply
with these reporting requirements, respondents must search their
records to identify any health and safety studies in their
possession, copy and process relevant studies, list studies that
are currently in progress, and submit this information to EPA. EPA
uses this information to construct a complete picture of the known
effects of the chemicals in question, leading to determinations by
EPA of whether additional testing of the chemicals is required. The
information enables EPA to base its testing decisions on the most
complete information available and to avoid demands for testing
that may be duplicative. EPA uses information obtained via this
collection to support its investigation of the risks posed by
chemicals and, in particular, to support its decisions on whether
to require industry to test chemicals under section 4 of
TSCA.
Although CBI substantiation has
added 31.5 burden hours per year to the total estimated burden,
there is an overall net decrease of 1,303 hours (from 1,605 to 302)
in the total estimated respondent burden compared with that
currently in the OMB inventory. This ICR assumes that a historical
average (from 1996 to present) of 13 chemicals will be added to the
section 8(d) list over the next three years. The previous ICR based
the average number of chemicals to be added to the section 8(d)
list on the period from 2006 2015. In 2006, 208 chemicals were
added to the list, the largest addition since 1996. The final
section 8(d) rule issued on January 20, 2008 (73 FR 5190) added 12
Lead and Lead Compounds to 40 CFR 716 120 was included in this ICR.
The number of chemicals added to the section 8(d) list has been
zero since early 2008. The methodology used in the previous ICR
overestimated the burden resulting from the addition of chemicals
to the TSCA section 8(d) rule.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
