Federal Register Proposed Rules, Rules and Notices for June 7,2013

June 7,2013


Environmental Impacts Statements; Notice of Availability [FR DOC# 2013-13597]

Proposed Information Collection Request; Comment Request; Exhaust Emissions of Light-Duty
Vehicles in Metropolitan Detroit; EPA ICR No. 2363.02 [FR DOC# 2013-13600] SUMMARY:The
Environmental Protection Agency is planning to submit an information collection request
(ICR), “Exhaust Emissions of Light-duty Vehicles in Metropolitan Detroit” (EPA ICR No.
2363.02, OMB Control No. 2060-0645) to the Office of Management and Budget (OMB) for
review and approval in accordance with the Paperwork Reduction Act (44 U.S.C. 3501 et
seq.). Before doing so, EPA is soliciting public comments on specific aspects of the
proposed information collection as described below. This is a proposed extension of the
ICR, which is currently approved through October 31, 2013. An Agency may not conduct or
sponsor and a person is not required to respond to a collection of information unless it
displays a currently valid OMB control number.

Trichloroethylene TSCA Chemical Risk Assessment; Notice of Public Meetings and Opportunity
to Comment [FR DOC# 2013-13576] SUMMARY:EPA’s contractor, The Scientific Consulting Group
(SCG), Inc., has identified a panel of scientific experts to conduct peer review of EPA’s
draft Toxic Substances Control Act (TSCA) chemical risk assessment, “TSCA Workplan
Chemical Risk Assessment for Trichloroethylene: Degreaser and Arts/Crafts Uses.” EPA will
hold three peer review meetings by web connect and teleconference. EPA invites the public
to register to attend the meetings as observers and/ or speakers providing oral comments
during any or all of the peer review meetings as discussed in this notice. The public may
also provide comment on whether they believe the appearance of conflict of interest exists
for any proposed peer review panel expert.

Biennial Determination of the Waste Isolation Pilot Plant’s Compliance With Applicable
Federal Environmental Laws for the Period 2010 to 2012 [FR DOC# 2013-13604] SUMMARY: Based
on documentation submitted by the U.S. Department of Energy (DOE) for the Waste Isolation
Pilot Plant (WIPP), the U.S. Environmental Protection Agency (EPA or “we”) determined
that, between 2010 and 2012, DOE operated the WIPP facility in compliance with applicable
Federal statutes, regulations, and permit requirements designated in Section 9(a)(1) of
the WIPP Land Withdrawal Act, as amended. The Secretary of Energy was notified of the
determination via a letter from EPA Acting Administrator Bob Perciasepe dated May 29,


Approval and Promulgation of Implementation Plans; North Carolina; Removal of Stage II
Gasoline Vapor Recovery Program [FR DOC# 2013-13610] SUMMARY:EPA is proposing to approve
changes to the North Carolina State Implementation Plan (SIP) submitted by the State of
North Carolina Department of Environment and Natural Resources (NC DENR), Division of Air
Quality on September 18, 2009, for the purpose of removing Stage II vapor control
requirements for new and upgraded gasoline dispensing facilities in the State. The
September 18, 2009, SIP revision also addresses several non-Stage II related rule changes.
However, action on the other portions for the September 18, 2009, SIP revision is being
addressed in a separate rulemaking action. EPA has preliminarily determined that North
Carolina’s September 18, 2009, SIP revision regarding the Stage II vapor control
requirements is approvable because it is consistent with the Clean Air Act (CAA or Act).

Approval and Promulgation of Air Quality Implementation Plans: North Carolina; Control
Techniques Guidelines and Reasonably Available Control Technology [FR DOC# 2013-13574]
SUMMARY:On May 1, 2013, the State of North Carolina, through the North Carolina Department
of Environment and Natural Resources (NC DENR), submitted to EPA a state implementation
plan (SIP) revision to satisfy North Carolina’s commitment associated with the conditional
approval of its reasonably available control technology (RACT) requirements for volatile
organic compound (VOC) sources located in the North Carolina portion of the Charlotte–
Gastonia–Rock Hill, North Carolina–South Carolina 1997 8-hour ozone nonattainment area
(hereafter referred to as the “bi-state Charlotte Area”). NC DENR’s May 1, 2013, SIP
revision also includes additional changes to North Carolina’s RACT rules. EPA is proposing
to approve these SIP revisions to the State’s RACT rules and to convert the existing
conditional approval of VOC RACT provisions in the North Carolina SIP to a full approval
under the Clean Air Act (CAA or Act). EPA has evaluated the proposed changes to North
Carolina’s SIP, and has made the preliminary determination that they are consistent with
statutory and regulatory requirements and EPA guidance.

Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating
Point Source Category [FR DOC# 2013-10191] SUMMARY:EPA is proposing a regulation that
would strengthen the controls on discharges from certain steam electric power plants by
revising technology-based effluent limitations guidelines and standards for the steam
electric power generating point source category. Steam electric power plants alone
contribute 50-60 percent of all toxic pollutants discharged to surface waters by all
industrial categories currently regulated in the United States under the Clean Water Act.
Furthermore, power plant discharges to surface waters are expected to increase as
pollutants are increasingly captured by air pollution controls and transferred to
wastewater discharges. This proposal, if implemented, would reduce the amount of toxic
metals and other pollutants discharged to surface waters from power plants. EPA is
considering several regulatory options in this rulemaking and has identified four
preferred alternatives for regulation of discharges from existing sources. These four
preferred alternatives differ with respect to the scope of requirements that would be
applicable to existing discharges of pollutants found in two wastestreams generated at
power plants. EPA estimates that the preferred options for this proposed rule would
annually reduce pollutant discharges by 0.47 billion to 2.62 billion pounds, reduce water
use by 50 billion to 103 billion gallons, cost $185 million to $954 million, and would be
economically achievable.
