Confidential Business Information (CBI) or other information whose disclosure is 

restricted by statute. Do not submit information that you consider to be CBI or otherwise 

protected through regulations.gov or e-mail. The regulations.gov website is an

comment directly to EPA without going through regulations.gov, your e-mail address 

will be automatically captured and included as part of the comment that is placed in the 

docket and made available on the Internet. If you submit an electronic comment, EPA 

recommends that you include your name and other contact information in the body of 

your comment and with any disk or CD-ROM you submit. If EPA cannot read your 

comment due to technical difficulties and cannot contact you for clarification, EPA may 

not be able to consider your comment. Electronic files should avoid the use of special 

characters, any form of encryption, and be free of any defects or viruses.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this Action Apply to Me?

This notice is directed to the public in general. It may, however, be of particular 

interest to you if you manufacture (defined by statute to include import) and/or process 

TSCA-covered chemicals and you may be identified by the North American Industrial 

Classification System (NAICS) codes 325 and 32411. Because this notice is directed to 

the general public and other entities may also be interested, the Agency has not attempted 

to describe all the specific entities that may be interested in this action. If you have any 

questions regarding the applicability of this action to a particular entity, consult the 

technical person listed under FOR FURTHER INFORMATION CONTACT.

B. What Should I Consider as I Prepare My Comments for EPA?

1. Submitting CBI. Do not submit this information to EPA through 

regulations.gov or e-mail. Clearly mark the part or all of the information that you claim 

to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the 

outside of the disk or CD-DOM as CBI and then identify electronically within the disk or 

CD-ROM the specific information that is claimed as CBI. In addition to one complete 

version of the comment that includes information claimed as CBI, a copy of the comment 

that does not contain the information claimed as CBI must be submitted for inclusion in 

the public docket. Information so marked will not be disclosed except in accordance with 

procedures set forth in 40 CFR part 2.

2. Tips for preparing your comments. When submitting comments, remember to:
5

i. Identify the document by docket ID number and other identifying information 

(subject heading, Federal Register date and page number).

ii. Follow directions. The Agency may ask you to respond to specific questions or 

organize comments by referencing a Code of Federal Regulations (CFR) part or section 

number.

iii. Explain why you agree or disagree; suggest alternatives and substitute 

language for your requested changes.

iv. Describe any assumptions and provide any technical information and/or data 

that you used.

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

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 
6

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

I. Background

The ITC was established by section 4(e) of TSCA “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 website (http://www.epa.gov/opptintr/itc) within a few days of submission to the 

EPA Administrator 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, 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. ITC's Activities During this Reporting Period (June 2010 to December 2010)

During this reporting period, the ITC reviewed the Nonylphenol (NP) & 

Nonylphenol Ethoxylates (NPEs) Action Plan available at
