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. 

Docket: All documents in the docket are listed in the docket index 

available at http://www.regulations.gov. Although listed in the index, 

some information is not publicly available, e.g., CBI or other 

information whose disclosure is restricted by statute. Certain other

in hard copy. Publicly available docket materials are available 

electronically at http://www.regulations.gov, or, if only available in hard

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 
3

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-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:

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 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. 

A. The 66th ITC Report 

The ITC is not making any changes to the TSCA section 4(e) Priority 

Testing List.

B. Status of the Priority Testing List

The Priority Testing List includes 2 alkylphenols, 12 lead 

compounds, 16 chemicals with insufficient dermal absorption rate data, 

and 207 High Production Volume (HPV) Challenge Program orphan 

chemicals.

organizations, and contract support provided by EPA. ITC members and staff 

are listed at the end of this report.
