Do not submit information that you consider to be CBI or otherwise protected through http://www.regulations.gov, or e-mail. The http://www.regulations.gov Web site is an “anonymous access” system, which means EPA will not know your identity or contact information unless you provide it in the body of your comment.

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. For additional information about EPA's public docket visit the EPA Docket Center homepage at http://www.epa.gov/epahome/dockets.htm.

A. 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. 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. 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:
- Identify the rulemaking by docket number and other identifying information (subject heading, Federal Register date and page number).
- 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.
- Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.
- Describe any assumptions and provide any technical information and/or data that you used.
- If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.
- Provide specific examples to illustrate your concerns, and suggest alternatives.
- Explain your views as clearly as possible, avoiding the use of profanity or personal threats.
- Make sure to submit your comments by the comment period deadline identified.
Under section 108(a) of the Clean Air Act (CAA), the Administrator identifies and lists certain pollutants which “cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare.” The EPA then issues air quality criteria for listed pollutants, which are commonly referred to as “criteria pollutants.” The 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 [a] pollutant in the ambient air, in varying quantities.” Under section 109 of the CAA, EPA establishes NAAQS for each listed pollutant, with the NAAQS based on the air quality criteria. Section 109(d) of the CAA requires periodic review and, if appropriate, revision of existing air quality criteria. The revised air quality criteria reflect advances in scientific knowledge on the effects of the pollutant on public health or welfare. The EPA is also required to periodically review and revise the NAAQS, if appropriate, based on the revised criteria.
Lead is one of six criteria pollutants for which EPA has established air quality criteria and NAAQS. Presently, EPA is reviewing the air quality criteria and NAAQS for lead.
As part of its review of the NAAQS, EPA is considering revising the associated monitoring requirements for lead (contained in 40 CFR parts 50, 53, and 58). On December 12, 2007, an advanced notice of proposed rulemaking (ANPR) was published (72 FR 71488). The ANPR identified a number of potential revisions to the monitoring requirements. A review of the ANPR was conducted by CASAC in December 2007, and a final report was submitted January 22, 2008 (EPA-CASAC-08-007). A consultation with the CASAC AAMM Subcommittee was held on March 25, 2008, to discuss the associated monitoring issues (73 FR 11113). A proposed rule was published May 20, 2008 (73 FR 29184).
The technical documents discuss the specifications and rationale for a lead in PM10 (Pb-PM10) Federal Reference Method (FRM) and criteria and testing procedures for either a lead in TSP (Pb-TSP) or Pb-PM10 Federal Equivalency Method (FEM). The technical documents will be available online at: http://www.epa.gov/ttn/amtic/casacinf.html.
The EPA is soliciting advice and recommendations from the CASAC AAMM Subcommittee by means of a peer review and consultation at an upcoming public teleconference of the CASAC AAMM Subcommittee. A separate Federal Register notice will inform the public of the date and phone number for the public teleconference. Following the CASAC AAMM Subcommittee public teleconference, EPA will consider comments received from the CASAC AAMM Subcommittee and the public in preparing the final revisions to the lead monitoring requirements as part of the lead NAAQS rulemaking.Start Signature
