Federal Register / Vol. 70, No. 167 / Tuesday, August 30, 2005 / Notices 51353 

associated with the Portland Maine 8- 

hour ozone 5 Percent Increment of 

Progress SIP are 20.115 tons per summer 

weekday of VOC and 39.893 tons per 

summer weekday of NOX. These 2007 

budgets cover Sagadahoc County and 

portions of York, Cumberland, and 

Androscoggin Counties. On July 12, 

2005, the availability of these budgets 

was posted on EPA’s website for the 

purpose of soliciting public comments. 

The comment period closed on August 

11, 2005, and EPA received no 

comments. 

Today’s notice is simply an 

announcement of a finding that we have 

already made. EPA New England sent a 

letter to Maine Department of 

Environmental Protection on August 12, 

2005, finding that the 2007 MOBILE6.2 

motor vehicle emissions budgets for the 

Portland Maine 8-hour ozone 

nonattainment area are adequate and 

must be used for transportation 

conformity determinations. 

Transportation conformity is required 

by section 176(c) of the Clean Air Act. 

EPA’s conformity rule, 40 CFR part 93, 

requires that transportation plans, 

programs, and projects conform to state 

air quality implementation plans and 

establishes the criteria and procedures 

for determining whether or not they do. 

Conformity to a SIP means that 

transportation activities will not 

produce new air quality violations, 

worsen existing violations, or delay 

timely attainment of the national 

ambient air quality standards. The 

criteria by which we determine whether 

a SIP’s motor vehicle emission budgets 

are adequate for conformity purposes 

are outlined in 40 CFR 93.118(e)(4). 

Please note that an adequacy review is 

separate from EPA’s completeness 

review, and it also should not be used 

to prejudge EPA’s ultimate approval of 

the SIP. Even if we find a budget 

adequate, the SIP could later be 

disapproved.

SUPPLEMENTARY INFORMATION: CASAC 

and the AAMM Subcommittee: The 

CASAC, which comprises seven 

members appointed by the EPA 

Administrator, was established under 

section 109(d)(2) of the Clean Air Act 

(CAA or Act) (42 U.S.C. 7409) as an 

independent scientific advisory 

committee, in part to provide advice, 

information and recommendations on 

the scientific and technical aspects of 

issues related to air quality criteria and 

national ambient air quality standards 

(NAAQS) under sections 108 and 109 of 

the Act. The CASAC, which is 

administratively located under the SAB 

Staff Office, is a Federal advisory 

committee chartered under the Federal 

Advisory Committee Act (FACA), as 

amended, 5 U.S.C., App. 

The SAB Staff Office established the 

CASAC AAMM Subcommittee in early 

2004 as a standing subcommittee to 

provide the EPA Administrator, through 

the CASAC, with advice and 

recommendations, as necessary, on 

topical areas related to ambient air 

monitoring, methods and networks. The 

Subcommittee complies with the 

provisions of FACA and all appropriate 

SAB Staff Office procedural policies. 

Background: Under section 108 of the 

CAA, the Agency is required to establish 

NAAQS for each pollutant for which 

EPA has issued criteria, including 

particulate matter (PM). Section 109(d) 

of the Act subsequently 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 and welfare. The Agency is also 

to revise the NAAQS, if appropriate, 

based on the revised criteria. 

EPA is currently reviewing the 

NAAQS for PM. As part of this review, 

the Agency is considering potential 

NAAQS for thoracic coarse particulate 

matter (PM10–2.5). Further information 

on EPA’s ongoing PM NAAQS review is 

available at the following URL: http:// 

www.epa.gov/ttn/naaqs/standards/pm/ 

s_pm_index.html. 

In conjunction with the review of the 

PM NAAQS, EPA is evaluating potential 

monitoring methods for measurement of 

PM10–2.5. The Agency’s Office of Air 

Quality Planning and Standards 

(OAQPS), within EPA’s Office of Air 

and Radiation (OAR), has requested that 

the CASAC conduct a peer review of the 

Federal Reference Method (FRM) for 

PM10–2.5 to provide independent 

scientific advice on the appropriateness 

of this method for being the basis of 

comparison in approving coarse-particle 

continuous monitors. The FRM for 

PM10–2.5 will establish the basis for 

approval of continuous-monitoring 

methods in a performance-based 

measurement system process. In 

addition, OAQPS has asked the CASAC 

to conduct a consultation to the Agency 

on: Fine particle (PM2.5) FRM 

optimization and equivalency criteria 

for continuous monitors; and PM10–2.5

methods evaluation, network data 

quality objectives (DQOs), and 

equivalency criteria for continuous 

monitors. The CASAC AAMM 

Subcommittee provided advice and 

recommendations for this ongoing work 

at a July 22, 2004 consultative meeting 

on PM10–2.5 methods and DQOs.

SUPPLEMENTARY INFORMATION: 

SUMMARY: Pursuant to the Federal 

Advisory Committee Act, Public Law 

92–463, Notice is hereby given that the 

Panel will hold a public meeting to 

conduct a consultation with EPA on a 

proposed framework for revising the 

Aquatic Life Criteria Guidelines. The 

dates and times for the meeting are 

provided above. 

Background: Background on the 

meeting described in this notice was 

provided in a Federal Register Notice 

published on February 15, 2005 (70 FR 

7734–7735). EPA’s recommended 

ambient water quality criteria for 

aquatic life provide guidance to states 

and tribes for adopting water quality 

standards which are the basis for 

controlling discharges or releases of 

pollutants. Currently, ambient water 

quality criteria for aquatic life 

protection are derived according to the 

Guidelines for Derivation of Ambient 

Water Quality Criteria for the Protection 

of Aquatic Life and Their Uses, 

published in 1985. EPA’s Office of 

Water has assessed the need to update 

the Guidelines, identified issues to be 

addressed in the Guidelines revisions, 

and will review the state-of-the-science 

and recommend new or improved 

approaches for deriving ambient water 

quality criteria. At the meeting, the SAB 

Aquatic Life Criteria Guidelines Panel 

will conduct a consultation with EPA 

on a proposed framework for improving 

the development of ambient water 

quality criteria. A roster of Panel 

members and their biosketches will be 

posted on the SAB website prior to the 

meeting. 

Availability of Meeting Materials: The 

meeting agenda and the charge to the 

SAB panel will be posted on the SAB 

website prior to the meeting. Meeting 

materials also include: (1) Four papers 

that provide an overview or framework 

of the approaches and methods being 

proposed for revising aquatic life water 

quality criteria; (2) an EPA report, 

Summary of Proposed Revisions to the 

Aquatic Life Criteria Guidelines; and (3) 

EPA’s Guidelines for Ecological Risk 

Assessment. EPA’s Guidelines for 

Ecological Risk Assessment are 

available at the following Web site: 

http://cfpub.epa.gov/ncea/raf/ 

recordisplay.cfm?deid=12460. Copies of 

other materials may be obtained by 

contacting Dr. Tala Henry, EPA Office of 

Water, by telephone: 202–566–1323, or 

e-mail: henry.tala@epa.gov.
