ENVIRONMENTAL PROTECTION 

AGENCY 

40 CFR Part 52 

[EPA–R03–OAR–2013–0650; FRL–9903–77– 

Region 3] 

Approval and Promulgation of Air 

Quality Implementation Plans; 

Maryland; State Boards Requirements 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA proposes to approve the 

State Implementation Plan (SIP) 

revision submitted by the State of 

Maryland for the purpose of addressing 

the State Boards’ requirements for all 

criteria pollutants of the National 

Ambient Air Quality Standards 

(NAAQS). 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 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final rule will be withdrawn and all 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. 

DATES: Comments must be received in 

writing by January 6, 2014. 

ADDRESSES: Submit your comments, 

identified by Docket ID Number EPA– 

R03–OAR–2013–0650 by one of the 

following methods:

Instructions: Direct your comments to 

Docket ID No. EPA–R03–OAR–2013– 

0650. EPA’s policy is that all comments 

received will be included in the public 

docket without change, and may be 

made available online at 

www.regulations.gov, including any 

personal information provided, unless 

the comment includes information 

claimed to be Confidential Business 

Information (CBI) or other information 

whose disclosure is restricted by statute. 

Do not submit information that you 

consider to be CBI or otherwise 

protected through www.regulations.gov 

or email. The 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 send an email 

comment directly to EPA without going 

through www.regulations.gov, your 

email address will be automatically 

captured and included as part of the 

comment that is placed in the public 

docket and made available on the 

Internet. 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. 

Docket: All documents in the 

electronic docket are listed in the 

www.regulations.gov index. Although 

listed in the index, some information is 

not publicly available, i.e., CBI or other 

information whose disclosure is 

restricted by statute. Certain other 

material, such as copyrighted material, 

is not placed on the Internet and will be 

publicly available only in hard copy 

form. Publicly available docket 

materials are available either 

electronically in www.regulations.gov or 

in hard copy during normal business 

hours at the Air Protection Division, 

U.S. Environmental Protection Agency, 

Region III, 1650 Arch Street, 

Philadelphia, Pennsylvania 19103. 

Copies of the State submittal are 

available at the Maryland Department of 

the Environment, 1800 Washington 

Boulevard, Suite 705, Baltimore, 

Maryland 21230.

action, with the same title, that is

section of this Federal Register 

publication. 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.
