[EPA–R06–OAR–2009–0214; FRL–8939–3] 

Approval and Promulgation of Air 

Quality Implementation Plans; Texas; 

Control of Emissions of Nitrogen 

Oxides (NOX) 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: The EPA is proposing to 

approve revisions to the Texas State 

Implementation Plan (SIP) that amend 

30 TAC Chapter 117, Control of Air 

Pollution from Nitrogen Compounds. 

On March 10, 2009, the State of Texas 

submitted a SIP revision containing 

amendments to the Beaumont-Port 

Arthur (BPA) 8-Hour Ozone 

Nonattainment Area Major Source rules, 

the Houston-Galveston-Brazoria (HGB) 

8-Hour Ozone Nonattainment Area 

Major Source rules, and the HGB 8-Hour 

Ozone Nonattainment Area Minor 

Source rules. These revisions will result 

in additional flexibility and consistency 

in the current stationary reciprocating 

internal combustion engine and gas 

turbine monitoring specifications found 

in Chapter 117 by allowing for an 

output-based option for monitoring 

nitrogen oxides (NOX) emissions. This 

additional option is expected to be 

equally effective as totalizing fuel flow 

meters in the monitoring of NOX

emissions at major stationary sources in 

the BPA 8-hour ozone nonattainment 

area and at both major and minor 

sources in the HGB 8-hour ozone 

nonattainment area. The EPA is 

proposing to approve these revisions 

pursuant to section 110 of the Federal 

Clean Air Act (CAA). 

DATES: Written comments must be 

received on or before August 31, 2009. 

ADDRESSES: Comments may be mailed to

SUPPLEMENTARY INFORMATION: In the 

final rules section of this Federal 

Register, EPA is approving the State’s 

SIP submittal as a direct final rule 

without prior proposal because the 

Agency views this as a noncontroversial 

submittal and anticipates no adverse 

comments. A detailed rationale for the 

approval is set forth in the direct final 

rule. If no relevant adverse comments 

are received in response to this action, 

no further activity is contemplated. If 

EPA receives adverse comments, the 

direct final rule will be withdrawn and 

all public comments received will be 

addressed in a subsequent final rule 

based on this proposed rule. EPA will 

not institute a second comment period. 

Any parties interested in commenting 

on this action should do so at this time. 

Please note that if EPA receives adverse 

comment on an amendment, paragraph, 

or section of this rule and if that 

provision may be severed from the 

remainder of the rule, EPA may adopt 

as final those provisions of the rule that 

are not the subject of an adverse 

comment. 

For additional information, see the 

direct final rule, which is located in the 

rules section of this Federal Register.

Approval and Promulgation of Air 

Quality Implementation Plans; 

Maryland; Determination of Clean Data 

for the 1997 Fine Particulate Matter 

Standard 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing to 

determine that the Baltimore, Maryland 

and Hagerstown-Martinsburg, Maryland 

(MD)-West Virginia (WV) nonattainment 

areas for the 1997 fine particulate matter 

(PM2.5) National Ambient Air Quality 

Standard (NAAQS) have clean data for 

the 1997 PM2.5 NAAQS. This proposed 

determination is based upon quality 

assured, quality controlled, and certified 

ambient air monitoring data showing 

that these areas have monitored 

attainment of the 1997 PM2.5 NAAQS 

based on the 2006–2008 data. In 

addition, quality controlled and quality 

assured monitoring data for 2009 that 

are available in the EPA Air Quality 

System (AQS) database, but not yet 

certified, show that these areas continue 

to meet the 1997 PM2.5 NAAQS. If this 

proposed determination is made final, 

the requirements for these areas to 

submit an attainment demonstration, 

associated reasonably available 

measures, a reasonable further progress 

plan, contingency measures, and other 

planning State Implementation Plans 

(SIPs) related to attainment of the 

standard shall be suspended for so long 

as each of these areas continue to meet 

the 1997 PM2.5 NAAQS.
