Airworthiness Directives; Dornier Luftfahrt GmbH Models Dornier 228-100, Dornier 228-101, Dornier 228-200, Dornier 228-201, Dornier 228-202, and Dornier 228-212 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Variable Annual Fee Structure for Power Reactors
The Nuclear Regulatory Commission (NRC) is considering whether to propose to amend its rule governing annual fees to establish a variable annual fee structure for power reactors based on licensed power limits. Current regulations governing annual fees require that each operating power reactor pay the same annual fee, regardless of the size of the reactor. The NRC has determined that the current single annual fee structure for power reactors should be reviewed in light of the potential for future licensing of small and medium sized nuclear reactors, some of which may not be used to generate electric power, and some of which may be used and licensed in configurations of up to twenty (20) reactors (modules). Although issuance of a license for a small or medium sized reactor which triggers imposition of fees may be several years in the future, this ANPR invites early input from interested stakeholders and the public on the issues relevant to the establishment of a variable annual fee structure for power reactors.
Mandatory Reliability Standards for the Calculation of Available Transfer Capability, Capacity Benefit Margins, Transmission Reliability Margins, Total Transfer Capability, and Existing Transmission Commitments and Mandatory Reliability Standards for the Bulk-Power System
Pursuant to section 215 of the Federal Power Act, the Commission proposes to approve six Modeling, Data, and Analysis Reliability Standards submitted to the Commission for approval by the North American Electric Reliability Corporation, the Electric Reliability Organization certified by the Commission. The proposed Reliability Standards require certain users, owners, and operators of the Bulk-Power System to develop consistent methodologies for the calculation of available transfer capability or available flowgate capability.
Standards for Business Practices and Communication Protocols for Public Utilities
The Federal Energy Regulatory Commission (Commission) proposes to incorporate by reference in its regulations the latest version (Version 002.1) of certain business practice standards adopted by the Wholesale Electric Quadrant of the North American Energy Standards Board (NAESB). NAESB's Version 002.1 Standards mainly modify NAESB's Version 001 Standards in response to Order Nos. 890, 890-A, and 890-B.
Mandatory Reliability Standards for Critical Infrastructure Protection
The Commission clarifies that the facilities within a nuclear generation plant in the United States that are not regulated by the U.S. Nuclear Regulatory Commission are subject to compliance with the eight mandatory ``CIP'' Reliability Standards approved in Commission Order No. 706.
Preventing Undue Discrimination and Preference in Transmission Service
The Federal Energy Regulatory Commission affirms its basic determinations in Order Nos. 890, 890-A and 890-B, granting rehearing and clarification regarding certain revisions to its regulations and the pro forma open-access transmission tariff, or OATT, adopted in Order Nos. 888 and 889 to ensure that transmission services are provided on a basis that is just, reasonable, and not unduly discriminatory. The Commission grants clarification of the degree of consistency required in the calculation of available transfer capability by transmission providers and denies rehearing regarding the requirement to undesignate network resources used to serve off-system sales
Special Local Regulation for Marine Events; Temporary Change of Dates for Recurring Marine Events in the Fifth Coast Guard District
The Coast Guard proposes to temporarily change the enforcement period of special local regulations for recurring marine events in the Fifth Coast Guard District. These regulations apply to only five recurring marine events that conduct on water activities such as power boat races, swimming competitions, and harbor celebrations. Special local regulations are necessary to provide for the safety of life on navigable waters during the event. This action is intended to restrict vessel traffic in portions of the Chester River, MD; Rappahannock River, VA; Elizabeth River, Southern Branch, VA; North Atlantic Ocean, Ocean City, MD; and Pasquotank River during each event.
Fenpropathrin; Pesticide Tolerances
This regulation establishes tolerances for residues of fenpropathrin in or on almond, hulls at 4.5 parts per million (ppm); cherry, sweet, at 5.0 ppm; cherry, tart at 5.0 ppm; fruit, stone, crop group 12 (except cherry) at 1.4 ppm; nuts, tree, crop group 14 at 0.10 ppm; pistachio at 0.10 ppm, PP 4E6867; avocado at 1.0 ppm; black sapote at 1.0 ppm; canistel at 1.0 ppm; maney sapote at 1.0 ppm; mango at 1.0 ppm; papaya at 1.0 ppm; sapodilla at 1.0 ppm; star apple at 1.0 ppm, PP 6E7066; caneberry, subgroup 13-07A at 12 ppm; and olive at 5.0 ppm, PP 7E7298. In addition, the Agency is deleting a time-limited tolerance on currant at 15 ppm which had an expiration date of 12/31/2008. The Interregional Research Project Number 4 (IR-4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
Performance Specification 16 for Predictive Emissions Monitoring Systems and Amendments to Testing and Monitoring Provisions
EPA is taking final action to promulgate Performance Specification (PS) 16 for predictive emissions monitoring systems (PEMS). Performance Specification 16 provides testing requirements for assessing the acceptability of PEMS when they are initially installed. Currently, there are no Federal rules requiring the use of PEMS; however, some sources have obtained Administrator approval to use PEMS as alternatives to continuous emissions monitoring systems (CEMS). Other sources may desire to use PEMS in cases where initial and operational costs are less than CEMS and process optimization for emissions control may be desirable. Performance Specification 16 will apply to any PEMS required in future rules in 40 CFR Parts 60, 61, or 63, and in cases where a source petitions the Administrator and receives approval to use a PEMS in lieu of another emissions monitoring system required under the regulation. We are also finalizing minor technical amendments.
Propiconazole; Pesticide Tolerances
This regulation establishes tolerances for combined residues of propiconazole in or on beet, garden, roots at 0.30 ppm; beet, garden, tops at 5.5 ppm; cilantro, leaves at 13 ppm; parsley, fresh leaves at 13 ppm; parsley, dried leaves at 35 ppm; pineapple at 4.5 ppm; and pineapple, process residue at 7.0 ppm. The Interregional Research Project Number 4 (IR-4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
Triethanolamine; Exemption from the Requirement of a Tolerance
This regulation establishes an exemption from the requirement of a tolerance for residues of triethanolamine (CAS Reg. No. 102-71-6) when used as an inert ingredient in pesticide formulations applied to growing crops under 40 CFR 180.920. Bayer CropScience, LP submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an expansion of the existing Sec. 180.920 exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of triethanolamine.
Thymol; Exemption from the Requirement of a Tolerance
This regulation establishes an exemption from the requirement of a tolerance for residues of thymol (as present in thyme oil) in or on food commodities when applied/used in/on public eating places, dairy processing equipment, and/or food processing equipment and utensils. Sensible Life Products submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of thymol.
Tristyrylphenol Ethoxylates (CAS Reg. No. 70559-25-0) and (CAS Reg. No. 99734-09-5); Exemption from the Requirement of a Tolerance
This regulation establishes an exemption from the requirement of a tolerance for residues of poly(oxy-1,2-ethanediyl), [alpha]- [2,4,6-tris(1-phenylethyl)phenyl]-[omega]-hydroxy- (CAS Reg. No. 70559- 25-0) and poly(oxy-1,2-ethanediyl), [alpha]-[tris(1- phenylethyl)phenyl]-[omega]-hydroxy-, (CAS Reg. No. 99734-09-5), herein referred to in this document as tristyrylphenol ethoxylates when used as inert ingredients in post-harvest applications to citrus crops, group 10, under 40 CFR 180.1288 at a maximum of 10.0% in pesticide formulations with azoxystrobin and fludioxonil. Syngenta Crop Protection, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of the tristyrylphenol ethoxylates.
Castor Oil, Ethoxylated, Oleate; Tolerance Exemption
This regulation establishes an exemption from the requirement of a tolerance for residues of castor oil, ethoxylated, oleate, minimum number average molecular weight (in amu) 2,000, (CAS No. 220037-02-05); when used as an inert ingredient in a pesticide chemical formulation. Goldschmidt Chemical Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of castor oil, ethoxylated, oleate on food or feed commodities.
Dinotefuran; Pesticide Tolerances for Emergency Exemptions
This regulation establishes time-limited tolerances for combined residues of dinotefuran, [ N -methyl- N '-nitro- N'' - ((tetrahydro-3-furanyl)methyl)guanidine] and its metabolites DN [1- methyl-3-(tetrahydro-3-furylmethyl)guanidine] and UF [1-methyl-3- (tetrahydro-3-furylmethyl)urea], expressed as dinotefuran in or on rice, grain. This action is in response to EPA's granting of an emergency exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on rice. This regulation establishes a maximum permissible level for residues of dinotefuran in this food commodity. The time-limited tolerance expires and is revoked on December 31, 2009.
Methods for Measurement of Filterable PM10
This action proposes amendments to Methods 201A and 202. The proposed amendments to Method 201A would add a particle-sizing device to allow for sampling of particulate matter (PM) with mean aerodynamic diameters less than or equal to 2.5 micrometers ([mu]m) (PM2.5 or fine PM). The proposed amendments to Method 202 would revise the sample collection and recovery procedures of the method to reduce the formation of reaction artifacts that could lead to inaccurate measurements of condensable particulate matter (CPM). Additionally, the proposed amendments to Method 202 would eliminate most of the hardware and analytical options in the existing method, thereby increasing the precision of the method and improving the consistency in the measurements obtained between source tests performed under different regulatory authorities. Finally, in this notice we are soliciting comments on whether to end the transition period for CPM in the New Source Review (NSR) program on a date earlier than the current end date of January 1, 2011. The proposed amendments would improve the measurement of fine particulates and would help State and local agencies in implementing CPM control measures to attain the PM2.5 National Ambient Air Quality Standards (NAAQS) which were established to protect public health and welfare.
Endangered and Threatened Wildlife and Plants; 12-Month Finding on a Petition To List the Yellow-Billed Loon as Threatened or Endangered
We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the yellow-billed loon (Gavia adamsii) as threatened or endangered, with critical habitat, under the Endangered Species Act of 1973, as amended (Act). The petitioners provided two listing options for consideration by the Service: (1) Listing the yellow-billed loon throughout its range, or (2) listing the United States population of the yellow-billed loon as a Distinct Population Segment (DPS). After a review of the best available scientific and commercial information, we have determined that listing the yellow-billed loon rangewide under the Act is warranted but precluded by other higher priority listing actions.
Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Update to Materials Incorporated by Reference
EPA is updating the materials submitted by Pennsylvania that are incorporated by reference (IBR) into the State implementation plan (SIP). The regulations affected by this update have been previously submitted by the Pennsylvania Department of Environmental Protection and approved by EPA. This update affects the SIP materials that are available for public inspection at the National Archives and Records Administration (NARA), the Air and Radiation Docket and Information Center located at EPA Headquarters in Washington, D.C., and the Regional Office.
Fisheries of the Exclusive Economic Zone Off Alaska; Central Gulf of Alaska Rockfish Program; Amendment 85
The North Pacific Fishery Management Council submitted Amendment 85 to the Fishery Management Plan for Groundfish of the Gulf of Alaska (GOA FMP) to NMFS for review. If approved, Amendment 85 would modify the GOA FMP and the Central Gulf of Alaska Rockfish Program to remove a restriction that prohibits certain catcher/processors from participating in directed groundfish fisheries in the Bering Sea and Aleutian Islands Management Area in July. This action is necessary to improve flexibility and reduce operating costs for catcher/processors that participate in the Central Gulf of Alaska Rockfish Program. This action is intended to promote the goals and objectives of the Magnuson- Stevens Fishery Conservation and Management Act, the GOA FMP, and other applicable laws.
Safety Zone: Hampton Roads Air Show, Back River, Hampton, VA
The Coast Guard proposes establishing a safety zone on the Back River in the vicinity of Hampton, VA during the Hampton Roads Air Show. This action is intended to restrict vessel traffic movement in the vicinity of Willoughby Point, VA to protect mariners from the hazards associated with air show events. We propose enforcement of this safety zone from 5 p.m. to 9 p.m. on April 24, 2009, and daily from 9 a.m. to 5 p.m. on April 25, and April 26, 2009.

Pennsylvania Regulatory Program
We are reinstating a requirement for the Pennsylvania regulatory program (the ``Pennsylvania program'') under the Surface Mining Control and Reclamation Act of 1977 (SMCRA or the Act). The requirement deals with documentation for the bonding provisions of the Pennsylvania program.
Prevailing Rate Systems; Redefinition of the New Haven-Hartford and New London, CT, Appropriated Fund Federal Wage System Wage Areas
The U.S. Office of Personnel Management (OPM) is issuing a proposed rule that would define the New Haven-Hartford and New London, CT, appropriated fund Federal Wage System (FWS) wage areas by county rather than by city and town boundaries. Defining the New England FWS wage areas by primarily considering county boundaries would provide greater consistency in how OPM defines FWS wage areas and would improve the ability to make direct data comparisons with Census Bureau data. The proposed rule would define the New Haven-Hartford wage area to include Hartford and New Haven Counties, CT, as the survey area and Fairfield, Litchfield, Middlesex, and Tolland Counties, CT, as the area of application and the New London wage area to include New London County, CT, as the survey area and Windham County, CT, as the area of application.
Safety Zones: Fireworks Displays in the Captain of the Port Portland Zone
The Coast Guard proposes the establishment of several safety zones in the Captain of the Port Portland, Oregon zone for annual fireworks displays that take place around the 4th of July each year. The safety zones are necessary to help ensure the safety of the maritime public during the events and will do so by prohibiting all persons and vessels from entering the safety zones unless authorized by the Captain of the Port Portland, Oregon or his designated representatives.
Concept Release on Whether To Eliminate the Bona Fide Hedge Exemption for Certain Swap Dealers and Create a New Limited Risk Management Exemption From Speculative Position Limits
In June and July of 2008, the Commodity Futures Trading Commission (''Commission'') issued a special call for information from swap dealers and index traders regarding their over-the-counter (``OTC'') market activities. In September of 2008, the Commission released a ``Staff Report on Commodity Swap Dealers and Index Traders with Commission Recommendations'' (the ``September 2008 Report'') with several preliminary Commission recommendations. Recommendation five of the September 2008 Report directs the staff to develop an advance notice of proposed rulemaking that would review whether to eliminate the bona fide hedge exemption for swap dealers and replace it with a limited risk management exemption that is conditioned upon, among other things, an obligation to report to the CFTC and applicable self- regulatory organizations when certain noncommercial swap clients reach a certain position level and/or a certification that none of a swap dealer's noncommercial swap clients exceed specified position limits in related exchange-regulated commodities.\1\
Environmental Impact and Related Procedures
The Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) issue this final rule that modifies our regulations to make certain changes mandated by the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). SAFETEA-LU prescribes additional requirements for environmental review and project decisionmaking that are not appropriately reflected in the existing FHWA-FTA joint National Environmental Policy Act (NEPA) procedures. Additionally, this final rule creates certain new categorical exclusions (CE) allowing proposed actions to proceed without an environmental assessment (EA) or environmental impact statement (EIS), and makes other minor changes to the joint procedures in order to improve the description of the procedures or to provide clarification with respect to the interpretation of certain provisions.
National Oil and Hazardous Substance Pollution Contingency Plan; National Priorities List
The Environmental Protection Agency (EPA) Region 8 is issuing a Notice of Intent for Partial Deletion of the surface and subsurface soils component of the Mouat Industries Superfund Site (Site) located in Columbus, Montana, from the National Priorities List (NPL) and requests public comments on this proposed action. The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is found at Appendix B of 40 CFR part 300, which is the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the State of Montana, through the Montana Department of Environmental Quality (MDEQ), have determined that all appropriate response actions at these identified parcels under CERCLA, other than five-year reviews and operation and maintenance, have been completed. However, this deletion does not preclude future actions under Superfund. This partial deletion pertains to the surface and subsurface soils component of the Mouat Industries Superfund Site. The groundwater component will remain on the NPL and is not being considered for deletion as part of this action.
National Oil and Hazardous Substance Pollution Contingency Plan; National Priorities List
The Environmental Protection Agency (EPA) Region 8 is publishing a direct final Notice of Partial Deletion of the surface and subsurface soil components of the Mouat Industries Superfund Site (Site), located in the Town of Columbus, Stillwater County, Montana, from the National Priorities List (NPL). The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This direct final partial deletion is being published by EPA with the concurrence of the State of Montana (State), through the Montana Department of Environmental Quality (MDEQ) because EPA has determined that all appropriate response actions at these identified parcels under CERCLA, other than five year reviews and operation and maintenance, have been completed. However, this partial deletion does not preclude future actions under Superfund.
Airworthiness Directives; Airbus Model A310 Series Airplanes and Model A300-600 Series Airplanes
This airworthiness directive (AD) supersedes two existing ADs. One AD applies to certain Airbus Model A310-200 and -300 series airplanes. That AD currently requires repetitive inspections for cracking of the flap transmission shafts, and replacement of the transmission shafts if necessary. That AD also provides an optional terminating action for the repetitive inspections. The other existing AD applies to all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes); and Model A310-200 and -300 series airplanes. That AD currently requires a one-time inspection of the trimmable horizontal stabilizer actuator (THSA), corrective actions if necessary, and follow-on repetitive tasks. This new AD also requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations and maintenance tasks for aging systems maintenance. This AD results from the manufacturer's determination that life limitations and maintenance tasks are necessary to ensure continued operational safety of the affected airplanes. We are issuing this AD to prevent reduced structural integrity of these airplanes due to the failure of system components.

This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Boeing Model 757-200, 757-200PF, and 757-300 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 757-200, 757-200PF, and 757-300 series airplanes. This AD requires, for certain airplanes, measuring the electrical bond resistance at certain stations and doing any applicable repair; installing support brackets for the hot short protector and new support clamps for the wire bundles; installing the equipment of the hot short protector; and modifying an existing wire bundle and installing a new wire bundle. This AD also requires, for certain other airplanes, measuring the electrical bond resistance at certain stations, measuring the electrical bonding resistance between the hot short protector and rear spar web, and doing any applicable repair. This AD also requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the center fuel tank densitometer from overheating and becoming a potential ignition source inside the fuel tank, which, in combination with flammable fuel vapors, could result in a center fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Boeing Model 767-200 and 767-300 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 767-200 and 767-300 series airplanes. This AD requires detailed inspections of the aft pressure bulkhead for damage, mid- frequency eddy current (MFEC) and low frequency eddy current (LFEC) inspections of radial web lap splices, tear strap splices, and super tear strap splices for cracking, and corrective actions if necessary. This AD results from analysis that indicates fatigue cracks of the web lap splice, tear strap splice, or super tear strap splice of the aft bulkhead are expected to occur on certain Boeing Model 767-200 and 767- 300 series airplanes. We are issuing this AD to detect and correct fatigue cracks of the aft pressure bulkhead, which could result in rapid decompression of the passenger compartment and possible damage or interference with airplane control systems that penetrate the bulkhead, and consequent loss of controllability of the airplane.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Fokker Model F.27 Mark 050 Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Fokker Model F.27 Mark 050 airplanes. The existing AD currently requires repetitive visual checks for oil leaks of both engines between the spinner and the engine cowling, and directly behind the heated intake lip of the engine; repetitive inspections for oil leaks at the feathering pump on both engines; and corrective actions if necessary. This new AD retains the requirements of the existing AD. This AD also requires replacing the outlet port (high-pressure) bobbin with a new, improved outlet port (high-pressure) bobbin, which terminates the repetitive visual checks and inspections. This AD results from reports of oil leakage at the engine feathering pump. We are issuing this AD to prevent oil loss from the feathering pump, which could cause the engine to shut down in flight.
Airworthiness Directives; Boeing Model 727-100 and 727-200 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 727-100 and 727-200 series airplanes. This AD requires repetitive internal and external high frequency eddy current, mid frequency eddy current, low frequency eddy current, and magneto optic imaging inspections to detect cracks, corrosion, delamination, and materials loss in the lower fastener row of the lower skin and the upper fastener row of the upper skin, and corrective actions if necessary. This AD results from a report of decompression in a Boeing Model 737 airplane at flight level 290. We are issuing this AD to detect and correct scratches and excessive reduction in material thickness from excessive blend-out or corrosion, which could lead to premature cracking in the lap joint. Such cracking could adversely affect the structural integrity of the airplane.
Airworthiness Directives; 328 Support Services GmbH Dornier Model 328-100 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Boeing Model 767 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767 airplanes. This AD requires repetitive inspections for cracking of the wing skin, and related investigative/ corrective actions if necessary. This AD results from reports of cracks found in the lower wing skin originating at the forward tension bolt holes of the aft pitch load fitting. We are issuing this AD to detect and correct cracking in the lower wing skin for the forward tension bolt holes at the aft pitch load fitting, which could result in a fuel leak and reduced structural integrity of the airplane.
