maintained as confidential, e.g., until a certain date, until the occurrence of a specified event, or permanently? If the occurrence of a specific event will eliminate the need for confidentiality, please specify that event.

2. Information submitted to EPA becomes stale over time. Why should the information you claim as confidential be protected for the time period specified in your answer to question no. 1?

3. What measures have you taken to protect the information claimed as confidential? Have you disclosed the information to anyone other than a governmental body or someone who is bound by an agreement not to disclose the information further? If so, why should the information still be considered confidential?

4. Is the information contained in any publicly available material such as the Internet, publicly available databases, promotional publications, annual reports, or articles? Is there any means by which a member of the public could obtain access to the information? Is the information of a kind that you would customarily not release to the public?

5. Has any governmental body made a determination as to the confidentiality of the information? If so, please attach a copy of the determination.

6. For each category of information claimed as confidential, explain with specificity why release of the information is likely to cause substantial harm to your competitive position. Explain the specific nature of those harmful effects, why they should be viewed as substantial, and the causal relationship between disclosure and such harmful effects. How could your competitors make use of this information to your detriment?

7. Do you assert that the information is submitted on a voluntary or a mandatory basis? Please explain the reason for your assertion. If the business asserts that the information is voluntarily submitted information, please explain whether and why disclosure of the information would tend to lessen the availability to EPA of similar information in the future.

8. Any other issue you deem relevant. Please note that you bear the burden of substantiating your confidentiality claim. Conclusory allegations will be given little or no weight in the determination. If you wish to claim any of the information in your response as confidential, you must mark the
response ‘‘ CONFIDENTIAL ’’ or with a similar designation, and must bracket all text so claimed. Information so designated will be disclosed by EPA only to the extent allowed by, and by means of, the procedures set forth in, 40 CFR part 2, subpart B. If you fail to claim the information as confidential, it may be made available to the requestor without further notice to you.

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

1. Submitting CBI. Do not submit this information to EPA through http:// www.regulations.gov or e-mail. Please submit this information by mail to the address identified in the **ADDRESSES** section of today’s notice for inclusion in the non-public CBI docket. 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 as CBI and then identify electronically within the disk or CD–ROM the specific information that is claimed as CBI. Information so marked will not be disclosed except in accordance with the procedures set forth in 40 CFR part 2, subpart B. In addition to the submission of 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.

2. Tips for Preparing Your Comments. When submitting comments, remember
to:

• Identify the notice by docket number and other identifying information (subject heading, Federal Register date and page number).

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

• Describe any assumptions and provide any technical information and/ or data that you used.

• Provide specific examples to illustrate your concerns, and suggest alternatives.

• Make sure to submit your comments by the comment period deadline identified.

**SUPPLEMENTARY INFORMATION :** 
I. Information About the Document

Section 108(a) of the Clean Air Act directs the EPA Administrator to identify certain pollutants that ‘‘ cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare ’’ and to issue air quality criteria for them. These air quality criteria are to ‘‘ accurately reflect the latest scientific knowledge useful in indicating the kind and extent of all identifiable effects on public health or welfare which may be expected from the presence of such pollutant in the ambient air * * *. ’’ Under section 109 of the Act, EPA is to establish national ambient air quality standards (NAAQS) for each pollutant for which EPA has issued criteria. Section 109(d) of the Act requires periodic review and, if appropriate, revision of existing air quality criteria to reflect advances in scientific knowledge on the effects of the pollutant on public health or welfare. EPA is also to revise the

NAAQS, if appropriate, based on the revised air quality criteria.

Carbon monoxide (CO) is one of six

‘‘ criteria’’ pollutants for which EPA has established NAAQS. Periodically, EPA reviews the scientific basis for these standards by preparing an Integrated Science Assessment (ISA) (formerly called an Air Quality Criteria Document). The ISA and supplementary annexes, in conjunction with additional technical and policy assessments, provide the scientific basis for EPA decisions on the adequacy of the current NAAQS and the appropriateness of possible alternative standards. The Clean Air Scientific Advisory Committee (CASAC), an independent science advisory committee whose review and advisory functions are mandated by Section 109(d)(2) of the Clean Air Act, is charged (among other things) with independent scientific review of EPA’s air quality criteria.

On September 13, 2007 (72 FR 52369), EPA formally initiated its current review of the air quality criteria for CO, requesting the submission of recent scientific information on specified topics. A workshop was held on January 28–29, 2008 (73 FR 2490) to discuss policy-relevant science to inform EPA’s planning for the CO NAAQS review. In March 2008, a draft of EPA’s ‘‘Plan for Review of the National Ambient Air Quality Standards for Carbon Monoxide ’’ (EPA–452/D–08–001) was made available for public comment and was discussed by the CASAC via a publicly accessible teleconference consultation on April 8, 2008 (73 FR 12998). EPA finalized the plan and made it available in August 2008 (EPA/ 452/R–08/005; http://www.epa.gov/ttn/ naaqs/standards/co/s

_ co

_ cr

_

pd.html). In November 2008, EPA held an authors’ teleconference to discuss, with invited scientific experts, preliminary draft materials prepared during the ongoing development of the CO ISA and its supplementary annexes.

The First External Review Draft ISA for CO (EPA/600/R–09/019; http:// cfpub.epa.gov/ncea/cfm/ recordisplay.cfm?deid=203935) was released for public comment and CASAC review on March 12, 2009 (74 FR 10734). This document was reviewed by the CASAC review panel and discussed at a public meeting held May 12–13, 2009 (74 FR 15265). The CASAC held a follow-up public teleconference on June 17, 2009 (74 FR 25530) to review and approve the CASAC CO Review Panel’s draft letter providing comments to EPA on the First External Review Draft ISA for CO. Following the teleconference, CASAC sent a final letter report to EPA on June 24, 2009 ( http://yosemite.epa.gov/sab/ sabproduct.nsf/4620a620d0120f 93852572410080d786/ 6E648129288BF930852575D F0070A528/$File/EPA-CASAC-09-011- unsigned.pdf ). The Second External Review Draft ISA for CO (EPA/600/R–09/019B; http://cfpub.epa.gov/ncea/cfm/ recordisplay.cfm?deid=213229 ), which took into consideration comments by CASAC and the public on the First External Review Draft, was released for public comment and CASAC review on September 23, 2009 (74 FR 48536). This document was reviewed by the CASAC review panel and discussed at a public meeting held November 16–17, 2009 (74FR 54042). The CASAC held a followup public teleconference on December 22, 2009 to review and approve the CASAC CO Review Panel’s draft letter providing comments to EPA on the Second External Review Draft ISA for CO. The final letter report can be obtained from the CASAC Web site ( http://yosemite.epa.gov/sab/ sabpeople.nsf/WebCommittees/CASAC ). EPA has considered comments by CASAC and by the public in preparing this final ISA.
