v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.

vi. Provide specific examples to illustrate your concerns and suggest alternatives.

vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

viii. Make sure to submit your comments by the comment period deadline identified. 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 73rd ITC Report
The ITC is revising the TSCA section 4(e) Priority Testing List by removing five HPV Challenge Program orphan chemicals.
B. Status of the TSCA Section 4(e) Priority Testing List

The TSCA section 4(e) Priority Testing List includes 2 alkylphenols, 45 HPV Challenge Program orphan chemicals, cadmium, a category of cadmium compounds, 6 non-phthalate plasticizers, 25 phosphate ester flame retardants, 2 other flame retardants, 9 chemicals to which children living near hazardous waste sites may be exposed, and 19 diisocyanates and related compounds.

The Toxic Substances Control Act (TSCA) Interagency Testing Committee (ITC) is revising the TCSA section 4(e) Priority Testing List by removing five High Production Volume (HPV) Challenge Program orphan chemicals. 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 EPA.

The TSCA section 4(e) Priority Testing List is Table 1 of this unit.

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 TSCA section 4(e) Priority Testing List with administrative and technical support from the ITC staff, ITC members, and their U.S. Federal Government organizations. ITC members and staff are listed at the end of this report. II. ITC’s Activities During This Reporting Period (June 2013 to November 2013)

During this reporting period, the ITC discussed the 50 HPV Challenge Program orphan chemicals remaining on the TSCA section 4(e) Priority Testing List. As a result of these discussions, the ITC removed 5 HPV Challenge Program orphan chemicals from the TSCA section 4(e) Priority Testing List. The hazard and fate testing data requested by the EPA for HPV Challenge Program orphan chemicals are necessary to


### 4070 Federal Register / Vol. 79, No. 15 / Thursday, January 23, 2014 / Notices

establish a screening level understanding of their potential human health and environmental impacts. The HPV Challenge Program orphan chemicals are discussed further in section III of this 73rd ITC Report.
III. Revisions to the TSCA Section 4(e) Priority Testing List: Removal of HPV Challenge Program Orphan Chemicals

In 2004, at EPA’s request, the ITC added 281 HPV Challenge Program orphan (unsponsored) chemicals to the Priority Testing List in the ITC’s 55th and 56th ITC Reports (Refs. 1 and 2). As of June 2013, 231 HPV Challenge Program orphan chemicals had been removed from the Priority Testing List because they were included in EPA’s test rules, the testing was voluntarily sponsored or because they no longer met the ≥ 1 million lb production or importation volume criterion for the HPV Challenge Program. During this reporting period, EPA requested that 5 HPV Challenge Program orphan chemicals be removed from the Priority Testing List in this 73rd ITC Report (Ref. 3). One of the HPV Challenge Program orphan chemicals is included in a HPV Challenge Program submission and 4 chemicals had production or importation volumes below 1 million lb reported to the 2006 Inventory Update Reporting (IUR) rule and the 2012 Chemical Data Reporting (CDR) rule. The five HPV Challenge Program orphan chemicals being removed from the Priority Testing List and the rationales for their removal are listed in Table 2 of this unit. The 45 HPV Challenge Program orphan chemicals remaining on the Priority Testing List are listed in Table 3 of this unit.
