II. Background

    The Toxic Substances Control Act (TSCA) (15 U.S.C. 260l et seq.) 
authorizes the Administrator of EPA to promulgate regulations under 
TSCA section 4(a) requiring testing of chemicals and chemical groups in 
order to develop data relevant to determining the risks that such 
chemicals and chemical groups may present to health or the environment. 
Section 4(e) of TSCA established the ITC to recommend chemicals and 
chemical groups to the Administrator of EPA for priority testing 
consideration. Section 4(e) of TSCA directs the ITC to revise the TSCA 
section 4(e) Priority Testing List at least every 6 months.
    You may access additional information about the ITC at http://www.epa.gov/opptintr/itc.

I. Background

    The ITC was established by TSCA section 4(e) ``to make 
recommendations to the Administrator respecting the chemical substances 
and mixtures to which the Administrator should give priority 
consideration for the promulgation of rules for testing under section 
4(a)* * *. At least every six months * * *, the Committee shall make 
such revisions to the Priority Testing List as it determines to be 
necessary and transmit them to the Administrator together with the 
Committee's reasons for the revisions'' (Pub. L. 94-469, 90 Stat. 2003 
et seq., 15 U.S.C. 2601 et seq.). ITC reports are available from 
regulations.gov (http://www.regulations.gov) after publication in the 
Federal Register. The ITC produces its revisions to the Priority 
Testing List with administrative and technical support from the ITC 
staff, ITC members, and their U.S. Government organizations, and 
contract support provided by EPA. ITC members and staff are listed at 
the end of this report.

II. TSCA Section 8 Reporting

A. TSCA Section 8 Reporting Rules

    Following receipt of the ITC's report (and the revised Priority 
Testing List) by the EPA Administrator, the EPA's Office of Pollution 
Prevention and Toxics (OPPT) may add the chemicals from the revised 
Priority Testing List to the TSCA section 8(a) Preliminary Assessment 
Information Reporting (PAIR) or the TSCA section 8(d) Health and Safety 
Data Reporting (HaSDR) rules. The PAIR rule requires manufacturers 
(including importers) of chemicals added to the

[[Page 46176]]

Priority Testing List to submit to EPA certain production and exposure 
information (http://www.epa.gov/oppt/chemtest/pubs/pairform.pdf). The 
HaSDR rule requires manufacturers (including importers) of chemicals 
added to the Priority Testing List to submit unpublished health and 
safety studies to EPA.

B. ITC's Use of TSCA Section 8 and Other Information

    The ITC's use of TSCA section 8 and other information is described 
in the ITC's 52nd Report (Ref. 1).

C. New Request To Add Chemicals to the TSCA Section 8(d) HaSDR Rule

    The ITC is requesting that EPA add the category of cadmium and 
cadmium compounds, including specifically cadmium and 103 cadmium 
compounds to the TSCA section 8(d) HaSDR rule. Cadmium and cadmium 
compounds are discussed in Unit IV. of this report.

III. ITC's Activities During This Reporting Period (December 2010 to 
May 2011)

    During this reporting period, the ITC discussed the draft TSCA 
section 4 proposed test rule, draft TSCA section 8(a) proposed 
reporting rule, and draft proposed TSCA section 5(a) Significant New 
Use Rule for nanoscale materials. In addition, the ITC discussed adding 
cadmium and cadmium compounds to the Priority Testing List and removing 
HPV Challenge Program orphan chemicals and lead and lead compounds from 
the Priority Testing List.

IV. Revisions to the TSCA Section 4(e) Priority Testing List

A. Chemicals Added to the Priority Testing List: Cadmium and Cadmium 
Compounds

    1. Recommendation. EPA requests that the ITC add the category 
``cadmium and cadmium compounds'' to the Priority Testing List to 
obtain use and exposure information on cadmium and cadmium compounds 
that are present in any consumer product.
    Required information would be limited to unpublished health and 
safety studies, including those relating to the cadmium content in 
consumer products containing cadmium or cadmium compounds, and/or 
studies that assess exposure to cadmium or cadmium compounds from such 
products. Exposure studies include any studies providing information 
about the solubility, bioavailability, and duration of exposure to 
cadmium or cadmium compounds from product use.
    2. Rationale for recommendation. EPA and the Consumer Product 
Safety Commission (CPSC) are concerned with the content of cadmium or 
cadmium compounds in certain children's toys, jewelry, and other 
consumer products due to known toxicity and health concerns from 
exposure to cadmium or cadmium compounds. CPSC and EPA have limited 
health and safety studies on the content of cadmium or cadmium 
compounds in consumer products. EPA is recommending that the ITC 
include the category listing for cadmium and cadmium compounds 
described in this unit. This will provide both EPA and CPSC with a 
streamlined means of obtaining studies. Information obtained on this 
category may assist both EPA and CPSC in taking further action as 
appropriate to protect consumers from exposure to cadmium or cadmium 
compounds in consumer products.
    3. Supporting information. The acute (short-term) effects of 
cadmium in humans through inhalation exposure consist mainly of effects 
on the lung, such as pulmonary irritation. Chronic (long-term) 
inhalation or oral exposure to cadmium leads to a build-up of cadmium 
in the kidneys that can cause kidney disease.
    Cadmium has been shown to be a developmental toxicant in animals, 
resulting in fetal malformations and other effects, but no conclusive 
evidence exists in humans. Animal studies have demonstrated an increase 
in lung cancer from long-term inhalation exposure to cadmium.\1\ EPA 
has classified cadmium as a Group B1, probable human carcinogen (http://epa.gov/ttn/atw/hlthef/cadmium.html).

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

    Cadmium has been found in certain consumer products: In 2010, CPSC 
found the amount of cadmium in samples of children's metal jewelry 
ranged from about 0.03 to 99% by weight. CPSC also assessed potential 
exposures to cadmium by extraction testing, including using an acid 
solution to simulate the effect of stomach acid. The CPSC Staff found 
that potential exposure to cadmium would exceed the acceptable daily 
intake levels for acute exposure to a child. CPSC recalled 26 items of 
jewelry in 4 separate recalls and issued a warning about 2 additional 
jewelry items.\2\ Cadmium was also found in the paint on glassware. 
CPSC issued a voluntary recall of 12 million ``Shrek'' movie themed 
collectable drinking glasses.\3\

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

    Due to the potential health effects of exposure to cadmium or 
cadmium compounds, EPA and CPSC are concerned about the possible 
presence and bioavailability of cadmium or cadmium compounds in 
consumer products generally. However, neither CPSC nor EPA currently 
has complete information for assessing the safety of any other consumer 
products that may contain cadmium or cadmium compounds.
    4. Information needs. EPA needs health and safety studies for 
assessing the extent and degree of exposure and potential hazard 
associated with these substances including: Epidemiological or clinical 
studies, occupational exposure and health effects studies, ecological 
effects studies, and environmental fate studies (including relevant 
physical chemical properties).
    Specifically EPA needs studies about the total amount of cadmium or 
cadmium compounds contained in a product, the solubility and 
bioavailability of cadmium or cadmium compounds (including 
accessibility of cadmium or cadmium compounds to children and studies 
of the age and foreseeable behavior of children exposed to a product 
for children and/or children's toys), the foreseeable duration and 
route of potential cadmium or cadmium compounds exposure through 
contact with products, and studies on the marketing, patterns of use, 
and lifecycle of cadmium-containing products.

B. Chemicals Removed From the Priority Testing List

    1. HPV Challenge Program orphan chemicals. Two hundred seventy 
(270) HPV Challenge Program orphan chemicals were added to the Priority 
Testing List in the 55th ITC Report (Ref. 2) and 5 were added to the 
Priority Testing List in the 56th ITC Report (Ref. 3).
    Thirty (30) HPV Challenge Program orphan chemicals were removed 
from the Priority Testing List in the 56th ITC Report. Eight (8) HPV 
Challenge Program orphan chemicals were removed from the Priority 
Testing List in the 58th ITC Report (Ref. 4). Thirty-five (35) HPV 
Challenge Program orphan chemicals were removed from the Priority 
Testing List in the 61st ITC Report (Ref. 5). One HPV Challenge Program 
Orphan chemical was removed from the Priority Testing List in the 63rd 
ITC Report (Ref. 6).
    In this ITC report 29 HPV Challenge Program orphan chemicals are 
being removed from the Priority Testing List because they were included 
in the EPA's TSCA section 4 proposed test rule (Ref. 7). (See Table 3 
of this unit.)

    2. Lead and lead compounds. Lead and lead compounds were added to 
the Priority Testing List in the ITC's 60th Report to obtain 
unpublished health and safety studies that relate to the lead content 
of consumer products that are ``intended for use by children'' and 
studies that assess children's exposure to lead from such products 
(Ref. 8). At this time the ITC is removing lead and lead compounds from 
the Priority Testing List because the EPA has reviewed the unpublished 
health and safety studies submitted in response to the TSCA section 
8(d) HaSDR rule (Ref. 9).
