ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R03-OAR-2017-0149; FRL-9967-89-Region 3]

Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; 2011 Base Year Inventory for the 2008 8-Hour Ozone National 
Ambient Air Quality Standard for the Maryland Portion of the 
Philadelphia-Wilmington-Atlantic City Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) proposes to approve, 
as a state implementation plan (SIP) revision, the 2011 base year 
inventory for the 2008 8-hour ozone national ambient air quality 
standard (NAAQS) for the Maryland portion of the Philadelphia-
Wilmington-Atlantic City marginal nonattainment area submitted by the 
State of Maryland through the Maryland Department of the Environment 
(MDE). 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 more detailed 
description of the state submittal and EPA's evaluation is included in 
a technical support document (TSD) prepared in support of this 
rulemaking action. A copy of the TSD is available, upon request, from 
the EPA Regional Office listed in the ADDRESSES section of this 
document or is also available electronically within the Docket for this 
rulemaking action. 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adverse comments, the direct final rule will be withdrawn and all 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 October 25, 2017.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R03-
OAR-2017-0149 at https://www.regulations.gov, or via email to 
stahl.cynthia@epa.gov. For comments submitted at Regulations.gov, 
follow the online instructions for submitting comments. Once submitted, 
comments

cannot be edited or removed from Regulations.gov. For either manner of 
submission, the EPA may publish any comment received to its public 
docket. Do not submit electronically any information you consider to be 
confidential business information (CBI) or other information whose 
disclosure is restricted by statute. Multimedia submissions (audio, 
video, etc.) must be accompanied by a written comment. The written 
comment is considered the official comment and should include 
discussion of all points you wish to make. EPA will generally not 
consider comments or comment contents located outside of the primary 
submission (i.e. on the web, cloud, or other file sharing system). For 
additional submission methods, please contact the person identified in 
the For Further Information Contact section. For the full EPA public 
comment policy, information about CBI or multimedia submissions, and 
general guidance on making effective comments, please visit https://www2.epa.gov/dockets/commenting-epa-dockets.
