Notification of a Public Teleconference of the Clean Air Act Advisory Committee (CAAAC)
The Environmental Protection Agency (EPA) announces a public teleconference of the Clean Air Act Advisory Committee (CAAAC). The EPA established the CAAAC on November 19, 1990, to provide independent advice and counsel to EPA on policy issues associated with implementation of the Clean Air Act of 1990. The Committee advises on economic, environmental, technical, scientific and enforcement policy issues.
Agency Information Collection Activities: Proposed Collections; Request for Comment on Two Proposed Information Collection Requests (ICRs)
The Environmental Protection Agency is planning to submit two information collection requests (ICRs), (see the item specific information provided in the text), 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 both ICRs, which are currently approved through July 31, 2013 and October 31, 2013, as specified for each item in the text below. 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.
Ocean Dumping; Atchafalaya-West Ocean Dredged Material Disposal Site Designation
The EPA is proposing to re-designate the existing Marine Protection, Research, and Sanctuaries Act of 1972 (MPRSA) Section 103(b) Atchafalaya-West Ocean Disposal Site (ODMDS-West) as a permanent MPRSA Section 102(c) ocean dredged material disposal site (ODMDS) located adjacent to and west of the Atchafalaya River Bar Channel (ARBC) of Louisiana. The approval for the ODMDS-West use expired in August 2012; therefore, the site can no longer accept shoal material dredged from the ARBC unless it is re-designated as a MPRSA Section 102(c) site by EPA. Studies have shown that use of the ODMDS-West reduces the amount and rate of shoal material runback into the ARBC, and thus, decreases the overall annual maintenance dredging effort needed for the ARBC while providing vessels with a longer period of safe navigation access prior to a maintenance dredging event. Therefore, there is a need to designate a permanent ODMDS on the west side of the ARBC. Approximately 10.8 million cubic yards will be placed every 7 months and must be conducted in accordance with the Site Management and Monitoring Plan. The proposed ODMDS will be monitored periodically to ensure that the site operates as expected.
Approval and Promulgation of Implementation Plans; Kentucky; Approval of Revisions to the Jefferson County Portion of the Kentucky SIP; Emissions During Startups, Shutdowns, and Malfunctions
EPA is proposing to approve part of a revision to the Kentucky State Implementation Plan (SIP), submitted by the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ), on March 22, 2011. The proposed revision was submitted by KDAQ on behalf of the Louisville Metro Air Pollution Control District (District), which has jurisdiction over Jefferson County, Kentucky. The portion of the revision that EPA is proposing for approval modifies the Regulation entitled, ``Emissions During Startups, Shutdowns, Malfunctions and Emergencies'' in the Jefferson County portion of the Kentucky SIP. EPA is proposing approval of this portion of the March 22, 2011, SIP revision because the Agency has determined that it is in accordance with the requirements for SIP provisions under the Clean Air Act (CAA or Act). EPA will act on the other portions of KDAQ's March 22, 2011, submittal, which are severable and unrelated, in a separate action.
Control of Air Pollution From Motor Vehicles: Tier 3 Motor Vehicle Emission and Fuel Standards
This action would establish more stringent vehicle emissions standards and reduce the sulfur content of gasoline beginning in 2017, as part of a systems approach to addressing the impacts of motor vehicles and fuels on air quality and public health. The proposed gasoline sulfur standard would make emission control systems more effective for both existing and new vehicles, and would enable more stringent vehicle emissions standards. The proposed vehicle standards would reduce both tailpipe and evaporative emissions from passenger cars, light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles. This would result in significant reductions in pollutants such as ozone, particulate matter, and air toxics across the country and help state and local agencies in their efforts to attain and maintain health-based National Ambient Air Quality Standards. Motor vehicles are an important source of exposure to air pollution both regionally and near roads. These proposed vehicle standards are intended to harmonize with California's Low Emission Vehicle program, thus creating a federal vehicle emissions program that would allow automakers to sell the same vehicles in all 50 states. The proposed vehicle standards would be implemented over the same timeframe as the greenhouse gas/fuel efficiency standards for light-duty vehicles, as part of a comprehensive approach toward regulating emissions from motor vehicles.
