SUPPLEMENTARY INFORMATION:
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.
B. Background
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.
