Federal Register Proposed Rules, Rules and Notices for July 23,2013

July 23,2013

NOTICES

California State Motor Vehicle Pollution Control Standards; Urban Buses;
Request for Waiver of Preemption; Notice of Decision [FR DOC# 2013-17700]
SUMMARY: EPA is granting the California Air Resources Board (CARB) its
request for a waiver of preemption for emission standards and related test
procedures contained in its urban bus regulations as they affect the 2002
and later model years. Urban buses are conventionally powered by a heavy-
duty diesel engine that falls within the heavy-duty vehicle classification
of greater than 33,000 pounds gross vehicle weight, and are intended
primarily for intra-city operation, i.e., within the confines of a city or
greater metropolitan area.

Notice of a Public Comment Period on the Draft IRIS Carcinogenicity
Assessment for Ethylene Oxide [FR DOC# 2013-17675] SUMMARY: EPA is
announcing a 45-day public comment period on the draft IRIS assessment
titled, “Evaluation of the Inhalation Carcinogenicity of Ethylene Oxide”
(EPA/635/R-13/128a) and on the draft peer review charge questions. The draft
assessment and draft peer review charge questions were prepared by the
National Center for Environmental Assessment (NCEA) within the EPA Office of
Research and Development (ORD). The 45-day public comment period on the
draft Evaluation of the Inhalation Carcinogenicity of Ethylene Oxide and on
the draft peer review charge questions begins on the day EPA posts the draft
assessment and the draft peer review charge questions on the IRIS Web site
and ends 45 days later. EPA anticipates posting the draft assessment and
draft charge questions on or around July 23, 2013. Shortly after the draft
carcinogenicity assessment is posted on the IRIS Web site, EPA will initiate
a peer review of the draft assessment, which EPA anticipates will be
undertaken by the Science Advisory Board. EPA is releasing this draft
carcinogenicity assessment for the purpose of public comment. This draft
assessment is not final, as described in EPA’s information quality
guidelines, and it does not represent and should not be construed to
represent Agency policy or views.

Circle Environmental #1 Superfund Site; Dawson, Terrell County, Georgia;
Notice of Settlement [FR DOC# 2013-17701] SUMMARY: Under 122(h) of the
Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA), the United States Environmental Protection Agency has entered into
a settlement with Walter G. Mercer, Jr. concerning the Circle Environmental
<greek-i>1 Superfund Site located in Dawson, Terrell County, Georgia. The
settlement addresses cost incurred by the agency in conducting a fund lead
Removal.
PROPOSED RULES

Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania;
Determinations of Attainment of the 1997 Annual Fine Particulate Standards
for the Liberty-Clairton Nonattainment Area [FR DOC# 2013-17688] SUMMARY:
EPA is proposing to make two separate and independent determinations
regarding the Liberty-Clairton, Pennsylvania 1997 annual fine particulate
(PM<INF>2.5</INF>) nonattainment area (the Liberty- Clairton Area). First,
EPA is proposing to determine that the Liberty- Clairton Area attained the
1997 PM<INF>2.5</INF> annual national ambient air quality standards (NAAQS)
by the applicable attainment date, December 31, 2011. This proposed
determination is based on quality assured and certified ambient air quality
date for the 2009- 2011 monitoring period. Second, EPA is proposing that the
Liberty- Clairton Area has continued to attain the 1997 annual
PM<INF>2.5</INF> NAAQS, based on quality-assured and certified ambient air
quality data for the 2010-2012 monitoring period. If EPA finalizes this
latter “clean data determination,” the requirement for the Liberty-
Clairton Area to submit an attainment demonstration, reasonably available
control measures (RACM), reasonable further progress (RFP), and contingency
measures related to attainment of the 1997 annual PM<INF>2.5</INF> NAAQS
would be suspended for so long as the area continues to attain the 1997
annual PM<INF>2.5</INF> NAAQS. These determinations do not constitute a
redesignation to attainment. The Liberty-Clairton Area will remain
designated nonattainment for the 1997 annual PM<INF>2.5</INF> NAAQS until
such time as EPA determines that the Liberty-Clairton Area meets the Clean
Air Act (CAA) requirements for redesignation to attainment, including an
approved maintenance plan. These proposed actions are being taken under the
CAA.

Notice of Data Availability Concerning Renewable Fuels Produced From Barley
Under the RFS Program [FR DOC# 2013-16928] SUMMARY: This Notice provides an
opportunity to comment on EPA’s draft analysis of the lifecycle greenhouse
gas (GHG) emissions of ethanol that is produced using barley as a feedstock.
EPA’s draft analysis indicates that ethanol produced from barley has an
estimated lifecycle GHG emissions reduction of 47% as compared to baseline
conventional fuel when the barley ethanol is produced at a dry mill facility
that uses natural gas for all process energy, uses electricity from the
grid, and dries up to 100% of distillers grains. Such barley ethanol would
therefore meet the minimum 20% GHG emissions reduction threshold for
conventional biofuels under the Clean Air Act Renewable Fuel Standard (RFS)
program. In addition, EPA analyzed two potential options for producing
barley ethanol that would meet the 50% GHG emissions reduction threshold for
advanced biofuels. Ethanol produced from dry- milling barley meet the
advanced biofuels GHG reduction threshold if it is produced at a facility
that uses no more than 30,700 Btu of natural gas for process energy, no more
than 4,200 Btu of biomass from barley hulls or biogas from landfills, waste
treatment plants, barley hull digesters, or waste digesters for process
energy, and no more than 0.84 kWh of electricity from the grid for all
electricity used at the renewable fuel production facility, calculated on a
per gallon basis. Ethanol produced from dry-milling barley can also meet the
advanced biofuel GHG reduction threshold if the production facility uses no
more than 36,800 Btu of natural gas for process energy and also uses natural
gas for on-site production of all electricity used at the facility other
than up to 0.19 kWh of electricity from the grid, calculated on a per gallon
basis.

Formaldehyde Emissions Standards for Composite Wood Products; Extension of
Comment Period [FR DOC# 2013-17673] SUMMARY: EPA issued a proposed rule in
the Federal Register of June 10, 2013, concerning formaldehyde emissions
standards for composite wood products. This document extends the comment
period from August 9, 2013, to September 9, 2013. After receiving requests
for an extension, EPA believes it is appropriate to extend the comment
period in order to give stakeholders additional time to assess the impacts
of the proposal, review technical documents in the docket, and prepare
comments.

Formaldehyde; Third-Party Certification Framework for the Formaldehyde
Standards for Composite Wood Products; Extension of Comment Period [FR DOC#
2013-17671] SUMMARY: EPA issued a proposed rule in the Federal Register of
June 10, 2013, concerning a third-party certification framework for the
formaldehyde standards for composite wood products. This document extends
the comment period from August 9, 2013 to August 26, 2013. After receiving
requests for an extension, EPA believes it is appropriate to extend the
comment period in order to give stakeholders additional time to assess the
impacts of the proposal, review technical documents in the docket, and
prepare comments.

Spring 2013 Regulatory Agenda [FR DOC# 2013-17068] SUMMARY: The
Environmental Protection Agency (EPA) publishes the semiannual regulatory
agenda online (the e-Agenda) at http:// http://www.reginfo.gov and at
http://www.regulations.gov to update the public about: <bullet> Regulations and
major policies currently under development, <bullet> Reviews of existing
regulations and major policies, and <bullet> Rules and major policymakings
completed or canceled since the last agenda.
