NOTICES

An Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol Bay, Alaska [FR
DOC# 2013-13451] SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing an
extension of the public comment period for 30 days for the revised draft document titled,
“An Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol Bay, Alaska”
(EPA-910-R-12-004Ba-c). The original Federal Register notice announcing the public comment
period was published on April 30, 2013. This extension is being granted in response to
requests from interested parties. The document was revised by EPA after reviewing comments
received from the public between May 18 and July 23, 2012, and input from the peer review
panel held in August 2012. EPA conducted this assessment to determine the significance of
Bristol Bay’s ecological resources and the potential impacts of large-scale mining on
these resources.

Adequacy Status of the Idaho, Northern Ada County PM10 [FR DOC# 2013-13449] SUMMARY: In
this notice, the EPA is notifying the public of its finding that the motor vehicle
emissions budgets (MVEBs) for particulate matter with an aerodynamic diameter of a nominal
10 microns or less (PM<INF>10</INF>), nitrogen oxides (NOx), and volatile organic
compounds (VOC) for the years 2008, 2015 and 2023 in the Northern Ada County
PM<INF>10</INF> State Implementation Plan, Maintenance Plan: Ten-Year Update (Maintenance
Plan Update) are adequate for transportation conformity purposes. The Maintenance Plan
Update was submitted to the EPA by the State of Idaho Department of Environmental Quality
(IDEQ or the State) on March 11, 2013, with a clarification to the MVEB submitted on April
16, 2013. As a result of this finding, the Community Planning Association of Southwest
Idaho, the Idaho Transportation Department and the U.S. Department of Transportation will
be required to use these MVEBs for future transportation conformity determinations.

PROPOSED RULES

Approval and Promulgation of Air Quality Implementation Plans; Delaware, District of
Columbia, Maryland, Pennsylvania, Virginia, and West Virginia; Removal of Obsolete
Regulations and Updates to Citations to State Regulations Due to Recodification [FR DOC#
2013-13351] SUMMARY: EPA is proposing to remove over fifty rules in the Code of Federal
Regulations (CFR) at 40 CFR part 52 for Delaware, the District of Columbia, Maryland,
Pennsylvania, Virginia, and West Virginia because they are unnecessary or obsolete. EPA is
also proposing to clarify regulations in 40 CFR part 52 which reflect updated citations of
certain Commonwealth of Virginia rules due to the Commonwealth’s recodification of its
regulations at the state level. These proposed actions make no substantive changes to
these State Implementation Plans (SIPs) and impose no new requirements. In the Final Rules
section of this Federal Register, EPA is approving these determinations 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.

Implementation of the 2008 National Ambient Air Quality Standards for Ozone: State
Implementation Plan Requirements [FR DOC# 2013-13233] SUMMARY: The EPA is proposing a rule
for implementing the 2008 ozone national ambient air quality standards (NAAQS) (the “2008
ozone NAAQS”) that were promulgated on March 12, 2008. This proposed rule addresses a
range of state implementation plan requirements for the 2008 ozone NAAQS, including
requirements pertaining to attainment demonstrations, reasonable further progress (RFP),
reasonably available control technology (RACT), reasonably available control measures
(RACM), new source review (NSR) requirements in nonattainment areas, emission inventories,
and the timing of state implementation plan (SIP) submissions and of compliance with
emission control measures in the SIP. Other issues also addressed in this proposed rule
are the revocation of the 1997 ozone NAAQS and anti-backsliding requirements that would
apply when the 1997 ozone NAAQS is revoked.

RULES

Approval and Promulgation of Air Quality Implementation Plans; Delaware, District of
Columbia, Maryland, Pennsylvania, Virginia, and West Virginia; Removal of Obsolete
Regulations and Updates to Citations to State Regulations Due to Recodification [FR DOC#
2013-13353] SUMMARY: EPA is taking direct final action to remove over fifty rules in the
Code of Federal Regulations (CFR) at 40 CFR part 52 for Delaware, the District of
Columbia, Maryland, Pennsylvania, Virginia, and West Virginia because they are unnecessary
or obsolete. EPA is also taking direct final action to clarify regulations in 40 CFR part
52 to reflect updated citations of certain Virginia rules due to the Commonwealth’s
recodification of its regulations at the state level. These direct final actions make no
substantive changes to these State Implementation Plans (SIPs) and impose no new
requirements. In the proposed rules section of this Federal Register, EPA is also
proposing to remove and clarify these regulations and is soliciting public comment. If
adverse comments are received on the direct final rule, EPA will withdraw the portions of
the final rule that triggered the comments. Any portions of the final rule for which no
adverse or critical comment is received will become final after the designated period.

Indiana: Final Authorization of State Hazardous Waste Management Program Revision [FR DOC#
2013-13445] SUMMARY: EPA is granting the State of Indiana final authorization of the
changes to its hazardous waste program under the Resource Conservation and Recovery Act
(RCRA). The Agency published a proposed rule on October 9, 2012, and provided for public
comment. EPA received no comments. No further opportunity for comment will be provided.
EPA has determined that these changes satisfy all requirements needed to qualify for final
authorization.
