EPA is announcing that Eastern Research Group, Inc. (ERG), an EPA contractor for external scientific peer review, will convene an independent panel of experts and organize and conduct an external peer review workshop to review the external review draft document titled, ``Toxicological Review of Thallium: In Support of Summary Information on the Integrated Risk Information System (IRIS)'' (NCEA-S-2949; EPA/ 635/R-08/001). EPA previously announced the 60-day public comment period (ending April 15, 2008) for the draft document in the Federal Register on February 15, 2008 (73 FR 8867).

EPA intends to forward public comments submitted in accordance with the Federal Register notice (73 FR 8867) to ERG for consideration by the external peer review panel prior to the workshop. EPA is releasing this draft document solely for the purpose of pre- dissemination peer review under applicable information quality guidelines. This document has not been formally disseminated by EPA. It does not represent and should not be construed to represent any Agency policy or determination. The public may attend this workshop as observers through a registration process, and time will be set aside for observers to give brief oral comments at the workshop regarding the draft document under review. Pre-registration is strongly recommended as space is limited, and registrations will be accepted on a first-come, first-served basis. The deadline for pre-registration is Monday, May 12, 2008. If space allows, registrations will continue to be accepted after this date, including on-site registrations. Time will be set aside to hear comments from observers, and individuals will be limited to a maximum of five minutes during the morning session of peer review workshop. When you register, please indicate that you wish to make oral comments during the comment period. The draft document and EPA's peer review charge are available via the Internet on NCEA's home page under the Recent Additions and the Data and Publications menus at http://www.epa.gov/ncea. When finalizing the draft document, EPA intends to consider the comments and recommendations from the external peer review workshop and any public comments that EPA receives in accordance with 73 FR 8867, February 15, 2008.

Approval and Promulgation of State Air Quality Plans for Designated Facilities and Pollutants; State of Maryland; Control of Large Municipal Waste Combustor (LMWC) Emissions From Existing Facilities
Document Number: E8-7347
Type: Rule
Date: 2008-04-08
Agency: Environmental Protection Agency
EPA is taking direct final action to approve the Maryland Department of the Environment (MDE) large municipal waste combustor plan (the plan) revision for implementing emission guideline (EG) amendments promulgated on May 10, 2006 by EPA under the Clean Air Act (the Act). The plan revision establishes revised emission limits, monitoring, and recordkeeping requirements for existing LMWC units with a unit capacity greater than 250 tons per day (TPD). An existing LMWC unit is one for which construction commenced on or before September 20, 1994.
Approval and Promulgation of State Air Quality Plans for Designated Facilities and Pollutants; State of Maryland; Control of Large Municipal Waste Combustor (LMWC) Emissions From Existing Facilities
Document Number: E8-7345
Type: Proposed Rule
Date: 2008-04-08
Agency: Environmental Protection Agency
EPA proposes to approve the Maryland Department of the Environment (MDE) large municipal waste combustor plan (the plan) revision for implementing Clean Air Act (the Act) emission guideline (EG) amendments promulgated by EPA on May 10, 2006. The plan revision establishes revised emission limits, monitoring, and recordkeeping requirements for existing LMWC units with a unit capacity greater than 250 tons per day (TPD). An existing LMWC unit is one for which construction commenced on or before September 20, 1994. In the Final Rules section of this Federal Register, EPA is approving the State's 111(d)/129 plan revision submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed description 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.
Approval and Promulgation of Implementation Plans; North Carolina: Approval of Revisions to the 1-Hour Ozone Maintenance Plan for the Raleigh/Durham and Greensboro/Winston-Salem/High Point Areas
Document Number: E8-7187
Type: Proposed Rule
Date: 2008-04-08
Agency: Environmental Protection Agency
EPA is proposing to approve a February 4, 2008, revision to the State Implementation Plan submitted by the North Carolina Department of Environment and Natural Resources on behalf of the State of North Carolina for the purpose of revising the subarea motor vehicle emissions budgets (MVEBs) for volatile organic compounds and nitrogen oxides for the Greensboro/Winston-Salem/High Point area. The Greensboro/Winston-Salem/High Point 1-hour ozone maintenance area (also referred to as the ``Triad Area'') is comprised of Davidson, Forsyth, and Guilford Counties and a portion of Davie County. The revisions to the subarea MVEBs are approvable because of an available safety margin for volatile organic compounds and nitrogen oxides for this Area. In the Final Rules Section of this Federal Register, EPA is approving the State's SIP revision 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 rule, 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 on this document. Any parties interested in commenting on this document should do so at this time.

The revisions to the subarea MVEBs are approvable because of an available safety margin for volatile organic compounds (VOC) and nitrogen oxides (NOX) for this Area.
NESHAP: National Emission Standards for Hazardous Air Pollutants: Standards for Hazardous Waste Combustors; Amendments
Document Number: E8-6667
Type: Rule
Date: 2008-04-08
Agency: Environmental Protection Agency
EPA is finalizing amendments to the national emission standards for hazardous air pollutants (NESHAP) for hazardous waste combustors, which EPA promulgated on October 12, 2005. The amendments to the October 2005 final rule clarify several compliance and monitoring provisions, and also correct several omissions and typographical errors in the final rule. We are finalizing the amendments to facilitate compliance and improve understanding of the final rule requirements. This rule does not address issues for which petitioners sought reconsideration. Nor does it address issues raised in EPA's comment solicitation of September 27, 2007.
