Approval and Promulgation of Air Quality Implementation Plans; West Virginia; Redesignation of the Weirton, WV Portion of the Steubenville-Weirton, OH-WV 8-Hour Ozone Nonattainment Area to Attainment and Approval of the Area's Maintenance Plan
EPA is approving a redesignation request and a State Implementation Plan (SIP) revision submitted by the State of West Virginia. The West Virginia Department of Environmental Protection (WVDEP) is requesting that the Brooke and Hancock County, West Virginia (Weirton) portion of the Steubenville-Weirton, OH-WV area (herein referred to as the ``Area'') be redesignated as attainment for the 8- hour ozone national ambient air quality standard (NAAQS). In conjunction with its redesignation request, the State submitted a SIP revision consisting of a maintenance plan for Weirton that provides for continued attainment of the 8-hour ozone NAAQS for the next 12 years, until 2018. EPA is also approving the adequacy determination for the motor vehicle emission budgets (MVEBs) that are identified in the Weirton 8-hour ozone maintenance plan for purposes of transportation conformity, and is approving those MVEBs. EPA is approving the redesignation request and the maintenance plan revision to the West Virginia SIP in accordance with the requirements of the CAA.
California State Motor Vehicle Pollution Control Standards; California Heavy-Duty On-Highway Otto-Cycle Engines and Incomplete Vehicles Regulations; Within-the-Scope Request; Opportunity for Public Hearing
The California Air Resources Board (CARB) has notified EPA that it has adopted amendments to the California heavy-duty otto-cycle regulations for 2004, 2005 through 2007, and for the 2008 and subsequent model years. Three different emissions standards apply to the 2004, 2005-2007, and 2008 model years respectively. By letter dated December 7, 2005, CARB submitted a request seeking EPA confirmation that its amendments affecting these model years be considered within- the-scope of previously granted waivers of preemption under section 209(b) of the Clean Air Act (CAA), 42 U.S.C. 7543(b). This notice announces that EPA has tentatively scheduled a public hearing concerning California's request and that EPA is accepting written comment on the request.
Enhancing Environmental Outcomes From Audit Policy Disclosures Through Tailored Incentives for New Owners; Notice
The Environmental Protection Agency (``EPA'' or ``the Agency'') requests comment on whether and to what extent the Agency should consider offering tailored incentives to encourage new owners of regulated entities to discover, disclose, correct, and prevent the recurrence of environmental violations. The Agency is considering whether actively encouraging such disclosures has the potential to yield significant environmental benefit, since new owners may be particularly well-situated and highly motivated to focus on, and invest in, making a clean start for their new facilities by addressing environmental noncompliance. Any tailored incentives for new owners would be beyond those offered as EPA is currently implementing EPA's April 11, 2000 policy on ``Incentives for Self-Policing: Discovery, Disclosure, Correction and Prevention of Violations,'' commonly referred to as the ``Audit Policy'' (65 FR 19618). These incentives would be designed to enhance implementation of the Audit Policy and encourage its use in the new owner context, but would not constitute a change to the Policy overall. After the comment period closes, the Agency plans to review all comments and decide whether to develop a pilot program to test the policy of offering tailored incentives to encourage new owners to self- audit and disclose under the Audit Policy. Should the Agency decide to proceed, EPA would then publish a second Federal Register notice to seek comment on a proposed pilot program. After a second round of public comment, the Agency would publish in the Federal Register: The final description of the pilot program; an announcement of its start date; and a description of how its success in achieving increased self- auditing and disclosure and significant improvement to the environment will be evaluated.
Approval and Promulgation of Implementation Plans; State of Iowa
EPA is approving a State Implementation Plan (SIP) submission by the state of Iowa which revises the air quality rules to include portions of the Federal New Source Review (NSR) regulations promulgated by EPA in December 2002. These revisions do not include the portion of the rules for nonattainment areas as there are currently no nonattainment areas in the state of Iowa. The definitions and applicability portions of the Prevention of Significant Deterioration (PSD) program were written into the state rules while the remaining portions of the PSD program were adopted by reference. All references to clean units and pollution control projects are not adopted by reference. Iowa has also not adopted portions of the Federal rule relating to exceptions from recordkeeping requirements.
Standards of Performance for Petroleum Refineries
EPA is proposing amendments to the current Standards of Performance for Petroleum Refineries. This action also proposes separate standards of performance for new, modified, or reconstructed process units at petroleum refineries. Unless otherwise noted, the term new includes modified or reconstructed units. The proposed standards for new process units include emissions limitations and work practice standards for fluid catalytic cracking units, fluid coking units, delayed coking units, process heaters and other fuel gas combustion devices, fuel gas producing units, and sulfur recovery plants. These proposed standards reflect demonstrated improvements in emissions control technologies and work practices that have occurred since promulgation of the current standards.
Multi-Agency Radiation Survey and Assessment of Materials and Equipment Manual
On January 16, 2007 (72 FR 1708) the Department of Defense (DoD), Department of Energy (DOE), U.S. Environmental Protection Agency (EPA), and the U.S. Nuclear Regulatory Commission (NRC) announced for public comment the availability of a draft document, entitled the ``Multi-Agency Radiation Survey and Assessment of Materials and Equipment Manual'' (MARSAME). A 90-day comment period was provided for the draft MARSAME that expired on April 16, 2007. A request for an extension to the comment period has been received from several stakeholders. The comment period for the draft manual has been reopened for an additional 30 days.
