MVEB is provided in the following 

table: 

HICKORY AREA NOX MVEB 

[kilograms per day] 

2009 

Catawba County ....................... 2,887,955 

Transportation conformity is required 

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

as amended in 1990. EPA’s conformity 

rule 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 (NAAQS). 

The criteria by which EPA determines 

whether a SIP’s MVEB is adequate for 

transportation conformity purposes are 

outlined in 40 Code of Federal 

Regulations (CFR) 93.118(e)(4). 

Additionally, the criteria by which EPA 

determines whether a particular 

pollutant/precursor is an insignificant 

contributor to the air quality problem in 

an area can be found at 40 CFR 

93.109(k). Insignificance findings are 

based on a number of factors, including 

the percentage of motor vehicle 

emissions in context of the total SIP 

inventory, the current state of air quality 

as determined by monitoring data for 

that NAAQS, the absence of SIP motor 

vehicle control measures, and historical 

trends and future projections of the 

growth of motor vehicle emissions. 

EPA’s rationale for the allowance of 

insignificance findings can be found in 

the July 1, 2004, revision to the 

transportation conformity rule at 69 

Federal Register (FR) 40004. 

Specifically, the rationale is explained 

on page 40061 under the subsection 

entitled ‘‘B. Areas With Insignificant 

Motor Vehicle Emissions.’’ 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 EPA finds the MVEB adequate 

or makes an insignificance finding 

through the adequacy process, the 

Agency may later disapprove the SIP. 

EPA has described the process for 

determining the adequacy of submitted 

SIP budgets in a May 14, 1999, 

memorandum entitled ‘‘Conformity 

Guidance on Implementation of March 

2, 1999 Conformity Court Decision.’’ 

EPA has followed this guidance in 

making this adequacy determination. 

This guidance is incorporated into 

EPA’s July 1, 2004, final rulemaking 

entitled ‘‘Transportation Conformity 

Rule Amendments for the New 8-hour 

Ozone and PM2.5 National Ambient Air 

Quality Standards and Miscellaneous 

Revisions for Existing Areas; 

Transportation Conformity Rule 

Amendments: Response to Court 

Decision and Additional Rule Changes’’ 

(69 FR 40004). 

Within 24 months from the effective 

date of this notice, the transportation 

partners will need to demonstrate 

conformity to the new MVEB if the 

demonstration has not already been 

made, pursuant to 40 CFR 93.104(e). 

(See 73 FR 4419 (January 24, 2008).) 

Additionally, the Transportation 

Conformity Rule at 40 CFR 93.109(k) 

states that a regional emissions analysis 

is no longer necessary for direct PM2.5

if EPA finds, through the adequacy or 

approval process, that regional motor 

vehicle emissions are an insignificant 

contributor to the air quality problem 

for that pollutant/precursor as 

demonstrated in the SIP. The 

insignificance finding should be noted 

in all future conformity determinations, 

and does not relieve the area of meeting 

all other transportation conformity 

requirements.

SUPPLEMENTARY INFORMATION: The SAB 

was established by 42 U.S.C. 4365 to 

provide independent scientific and 

technical advice to the Administrator on 

the technical basis for Agency positions 

and regulations. The SAB is a Federal 

advisory committee chartered under the 

Federal Advisory Committee Act 

(FACA), as amended, 5 U.S.C., App 2. 

The SAB will comply with the 

provisions of FACA and all appropriate 

SAB Staff Office procedural policies. 

Pursuant to the Federal Advisory 

Committee Act, Public Law 92–463, 

notice is hereby given that a workgroup 

of the chartered SAB will hold a public 

meeting to lead the review of the 

implementation of SAB’s previous 

recommendations for the revision of 

EPA’s cancer risk assessment of 

inorganic arsenic. 

Background: The EPA is currently in 

the process of updating the 1988 IRIS 

cancer assessment for inorganic arsenic 

(iAs). The EPA evaluated and 

implemented the National Research 

Council (2001) recommendations and in 

2005 requested that the SAB review the 

Agency’s draft cancer assessment for 

iAs. The SAB review report was 

finalized in 2007 and is available at the 

following URL: http://yosemite.epa.gov/

EPA’s Office of Research 

Development has completed a 2010 

draft ‘‘Toxicological Review of Inorganic 

Arsenic: In Support of the Summary 

Information on the Integrated Risk 

Information System (IRIS)’’ (EPA/635/R– 

10/001). This draft assessment includes 

an evaluation and characterization of 

mstockstill on DSKH9S0YB1PROD with NOTICES

9206 Federal Register / Vol. 75, No. 39 / Monday, March 1, 2010 / Notices 

the potential cancer hazard of iAs and 

a quantitative dose-response cancer 

assessment for iAs. The draft assessment 

also provides a disposition of SAB’s 

previous review comments and 

recommendations. 

In response to the Administrator’s 

request, ORD is requesting that the SAB 

evaluate and comment on EPA’s 

interpretation and implementation of 

the key SAB (2007) recommendations in 

the revised draft assessment. ORD is 

requesting an expedited and focused 

review of the draft assessment in three 

areas: Evaluation of epidemiological 

literature; dose-response modeling 

approaches; and the sensitivity analysis 

of the exposure assumptions used in the 

risk assessment. In response to this 

request, the SAB is convening a 

workgroup of the chartered SAB to lead 

this expedited and focused review and 

to assess the responsiveness of EPA’s 

implementation of the previous SAB 

recommendations. The SAB 

workgroup’s draft report will be 

reviewed and approved by the full 

Board in a subsequent public meeting to 

be announced in a separate Federal 

Register notice. Information about this 

SAB advisory activity can be found on
