Act (TSCA) Interagency Testing 

Committee (ITC) transmitted its 71st ITC 

Report to the EPA Administrator on 

November 14, 2012. In the 71st ITC 

Report, which is included with this 

notice, the ITC is revising the TSCA 

section 4(e) Priority Testing List by 

removing 16 High Production Volume 

(HPV) Challenge Program orphan 

chemicals. The ITC is removing these 16 

chemicals because actions have been 

taken to assess their hazardous 

potential.

II. Background 

The Toxic Substances Control Act 

(TSCA) (15 U.S.C. 260l et seq.) 

authorizes the EPA Administrator 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 EPA Administrator 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/oppt/itc. 

A. The 71st ITC Report

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’’ 

(Public Law 94–469, 90 Stat. 2003 et 

seq., 15 U.S.C. 2601 et seq.). ITC reports 

are available from the ITC’s Web site 

(http://www.epa.gov/oppt/itc) and 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 and 

ITC members. ITC members and staff are 

listed at the end of this report.

II. ITC’s Activities During This 

Reporting Period (June to October 2012) 

During this reporting period, the ITC 

discussed the 164 High Production 

Volume (HPV) Challenge Program 

orphan chemicals remaining on the 

TSCA section 4(e) Priority Testing List. 

As a result of these discussions, the ITC 

removed 16 HPV Challenge Program 

orphan chemicals from the TSCA 

section 4(e) Priority Testing List. Orphan 

chemicals are those HPV chemicals for 

which no sponsors have volunteered to 

develop and submit robust summaries 

of basic hazard and fate testing data to 

the EPA. The hazard and fate testing 

data requested by the ITC for HPV 

Challenge Program orphan chemicals 

are necessary to establish a screening 

level understanding of their potential 

human health and environmental 

impacts. 

III. HPV Challenge Program Orphan 

Chemicals Removed From the TSCA 

Section 4(e) Priority Testing List 

The Chemical Abstract Service (CAS) 

Registry numbers and names of the 16 

HPV Challenge Program orphan 

chemicals being removed from the 

Priority Testing List are listed in Table 

2 of this unit. Also listed in Table 2 of 

this unit are the ITC reports in which 

the HPV Challenge Program orphan 

chemicals were added to the Priority 

Testing List and the rationale for their 

removal. The Universal Resource 

Locators (URLs or Web site addresses) 

provide additional information about 

the disposition of these chemicals and 

are included as footnotes to Table 2 of 

this unit.

NOTE: OECD SIDS program = Organization for Economic Cooperation and Development Screening Information Data Set program. 

Fourteen of the HPV Challenge 

Program orphan chemicals that were 

removed from the Priority Testing List in 

this 71st ITC Report were added to the 

Priority Testing List in the 55th ITC 

Report (Ref. 1). Two of the HPV 

Challenge Program orphan chemicals 

that were removed from the Priority 

Testing List in this 71st ITC Report were 

added to the Priority Testing List in the 

56th ITC Report (Ref. 2). Six of the HPV 

Challenge Program orphan chemicals 

were removed because they were added 

to a Notice of Proposed Rulemaking 

(NPRM) that proposed to require 

manufacturers and processors of these 

chemicals to conduct testing for acute 

toxicity, repeated dose toxicity, 

developmental and reproductive 

toxicity, genetic toxicity, ecotoxicity, 

and environmental fate (Ref. 3). Three of 

the HPV Challenge Program orphan 

chemicals were removed because they 

were in the Organization for Economic 

Cooperation and Development (OECD) 

Screening Information Data Set (SIDS) 

program (http://www.epa.gov/opptintr/ 

chemtest/pubs/oecdsids.html). The 

URLs for the three OECD SIDS 

chemicals are provided as footnotes b, e, 

and i to Table 2 of this unit. Six of the 

HPV Challenge Program orphan 

chemicals were removed because their 

testing was sponsored by the chemical’s 

producers. The URLs for the six 

sponsored chemicals are provided as 

footnotes c, d, f, and g to Table 2 of this 

unit. One chemical was removed 

because it was an analog to a chemical 

with robust summaries and test plans. 

The URL for that chemical is provided 

as footnote h to Table 2 of this unit.
