Approval and Promulgation of Implementation Plans; California; Revisions to the California State Implementation Plan Pesticide Element
EPA proposes to approve several revisions to the Pesticide Element of the California state implementation plan (SIP). These revisions include regulations adopted by the California Department of Pesticide Regulation (CDPR) that: (1) Reduce volatile organic compound (VOC) emissions from the application of agricultural field fumigants in the South Coast, Southeast Desert, Ventura, San Joaquin Valley (SJV), and Sacramento Metro ozone nonattainment areas by restricting fumigant application methods; (2) establish a contingency fumigant emissions limit and allocation system for Ventura; (3) require CDPR to prepare and make available to the public an annual pesticide VOC emissions inventory report; and (4) require recordkeeping and reporting of pesticide usage. EPA also proposes to approve CDPR's commitments to manage VOC emissions from the use of agricultural and commercial structural pesticides in the SJV to ensure that they do not exceed 18.1 tons per day and to implement restrictions on VOC emissions in the SJV from non-fumigant pesticides by 2014. Lastly, EPA is providing its response to a remand by the Ninth Circuit Court of Appeals of EPA's 2009 approval of a revision to the California SIP related to reducing VOC emissions from pesticides.
International Services Surveys and Direct Investment Surveys Reporting
The Bureau of Economic Analysis (BEA) revises its rules to establish general guidelines for how BEA will collect data on international trade in services and direct investment surveys, which are provided for by the International Investment and Trade in Services Survey Act (the Act). In addition to the Act, the Omnibus Trade and Competitiveness Act of 1988 authorizes BEA to conduct international trade in services surveys. Currently, international trade in services and direct investment surveys are promulgated through separate rulemaking actions. This final rule modifies BEA's regulations to allow BEA to issue surveys through notices rather than through notice and comment rulemaking. It also provides a more general framework for how BEA collects data on these surveys that are required, or provided for, by the statutes. This rule will simplify and generalize existing regulations governing the procurement of information on international trade in services and direct investment.
Modification of Significant New Uses of Tris Carbamoyl Triazine; Technical Amendment
This technical amendment implements a technical correction that published in the Federal Register of March 7, 2012. Specifically, the correction involves the removal of a cross-reference that was erroneously included in a final rule that published in the Federal Register of February 8, 2012.
Energy Conservation Program: Test Procedures for Residential Clothes Washers; Correction
This final rule corrects the provisions for calculating the annual operating cost of residential clothes washers. In the final rule establishing new and amended test procedures for residential clothes washers, published in the Federal Register on March 7, 2012, and effective as of April 6, 2012, the U.S. Department of Energy (DOE) erroneously referenced the new test procedure, rather than the currently effective test procedure, in one section of the provisions for calculating annual operating cost.
Medicare and Medicaid Programs: Hospital Outpatient Prospective Payment; Ambulatory Surgical Center Payment; Hospital Value-Based Purchasing Program; Physician Self-Referral; and Patient Notification Requirements in Provider Agreements; Corrections
This document corrects technical errors that appeared in the final rule with comment period published in the Federal Register on November 30, 2011, entitled ``Medicare and Medicaid Programs: Hospital Outpatient Prospective Payment; Ambulatory Surgical Center Payment; Hospital Value-Based Purchasing Program; Physician Self-Referral; and Patient Notification Requirements in Provider Agreements'' and in the correction notice published in the Federal Register on January 4, 2012, entitled ``Medicare and Medicaid Programs: Hospital Outpatient Prospective Payment; Ambulatory Surgical Center Payment; Hospital Value-Based Purchasing Program; Physician Self-Referral; and Patient Notification Requirements in Provider Agreements; Corrections.''
Approval and Promulgation of Implementation Plans: Georgia; Approval of Substitution for Transportation Control Measures
EPA is making an administrative change to update the Code of Federal Regulations (CFR) to reflect a change made to the Georgia State Implementation Plan (SIP) on November 5, 2009, as a result of EPA's concurrence on a substitute transportation control measure (TCM) for the Atlanta portion of the Georgia SIP. On February 5, 2010, the State of Georgia, through the Environmental Protection Division (EPD), submitted a revision to the Georgia SIP requesting that EPA update its SIP to reflect a substitution of a TCM. The substitution was made pursuant to the TCM substitution provisions contained in Clean Air Act (CAA). EPA concurred on this substitution on November 5, 2009. In this administrative action, EPA is updating the non-regulatory provisions of the Georgia SIP to reflect the substitution. In summary, the substitution that EPA concurred on was a conversion of high occupancy vehicle (HOV) lanes to high occupancy toll lanes (HOT). EPA has determined that this action falls under the ``good cause'' exemption in the Administrative Procedures Act (APA) which, upon finding ``good cause,'' authorizes agencies to dispense with public participation which allows an agency to make an action effective immediately (thereby avoiding the 30-day delayed effective date otherwise provided for in the APA).
Approval and Promulgation of Air Quality Implementation Plans; Wisconsin; Milwaukee-Racine Nonattainment Area; Determination of Attainment for the 2006 24-Hour Fine Particle Standard
EPA is proposing to determine that the Milwaukee-Racine, Wisconsin area has attained the 2006 24-hour fine particle (PM2.5) National Ambient Air Quality Standard (NAAQS). This proposed determination is based upon quality assured, quality controlled, and certified ambient air monitoring data, from the 2008- 2010 monitoring period, supplemented by statistical analysis of these data, showing that the area has monitored attainment of the 2006 24- hour PM2.5 NAAQS. Data available to date for 2011 are consistent with continued attainment. On March 7, 2011, the Wisconsin Department of Natural Resources (WDNR) requested that EPA approve its request for a determination that the Milwaukee-Racine area has attained the standard. If EPA finalizes this proposed determination, the requirement for the State of Wisconsin to submit an attainment demonstration, associated reasonably available control measures (RACM) to include reasonably available control technology (RACT), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plan (SIP) revisions related to attainment of the standard shall be suspended for so long as the area continues to attain the 2006 24-hour PM2.5 NAAQS.
Standards for Business Practices and Communication Protocols for Public Utilities
The Federal Energy Regulatory Commission (Commission) is proposing to amend its regulations to incorporate by reference the business practice standards adopted by the Wholesale Electric Quadrant of the North American Energy Standards Board (NAESB) that pertain to the measurement and verification of demand response and energy efficiency resources participating in organized wholesale electricity markets. NAESB adopted the measurement and verification of demand response standards in response to the Commission's findings in Order No. 676-F.
Airworthiness Directives; Empresa Brasileria de Aeronáutica S.A. (EMBRAER) Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Empresa Brasileria de Aeron[aacute]utica S.A. (EMBRAER) Model EMB-505 airplanes. 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 an inadequate amount of drain holes in the primary control surfaces (rudder, elevator, and aileron) and their tab surfaces may allow water to accumulate in the control surfaces. This condition could cause unbalanced flight control surfaces and reduced flutter margins, which could result in loss of control of the airplane. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Sicma Aero Seat Passenger Seat Assemblies, Installed on, But Not Limited to, ATR-GIE Avions de Transport Régional Airplanes
We are superseding an existing airworthiness directive (AD) for certain Sicma Aero Seat Model 9401, 9402, 9404, 9505, 9406, 9407, 9408, and 9409 series passenger seat assemblies, installed on, but not limited to, ATRGIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. That AD currently requires repetitive detailed inspections for cracking of the central and lateral spreaders of the affected seats, and repair or replacement of the spreader if necessary. This AD was prompted by a determination that the existing AD included Model 9505 series passenger seat assemblies in the applicability instead of Model 9405 series passenger seat assemblies. We are issuing this AD to detect and correct cracking of the central and lateral spreaders, which could lead to further cracking of the seat spreaders, causing injury to passengers or crew members during heavy turbulence in flight or in the event of an emergency landing.
Disclosure of Information for Certain Intellectual Property Rights Enforced at the Border
This document amends, on an interim basis, the U.S. Customs and Border Protection (CBP) regulations pertaining to importations of merchandise bearing recorded trademarks or recorded trade names. The interim amendments, effective upon publication in the Federal Register, allow CBP, subject to limitations, to disclose to an intellectual property right holder information appearing on merchandise or its retail packaging that may comprise information otherwise protected by the Trade Secrets Act, for the purpose of assisting CBP in determining whether the merchandise bears a counterfeit mark. Such information will be provided to the right holder in the form of photographs or a sample of the goods and/or their retail packaging in their condition as presented to CBP for examination and alphanumeric codes appearing on the goods. The information will include, but not be limited to, serial numbers, universal product codes, and stock keeping unit (SKU) numbers appearing on the imported merchandise and its retail packaging, whether in alphanumeric or other formats. These changes provide a pre-seizure procedure for disclosing information about imported merchandise suspected of bearing a counterfeit mark for the limited purpose of obtaining the right holder's assistance in determining whether the mark is counterfeit or not.

Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This AD was prompted by multiple reports of short circuit events during pre- delivery inspections and test flights, one of which resulted in smoke in the cockpit. This AD requires replacing or relocating of certain circuit breaker panel (CBP) bus bars on certain airplanes, inspecting for any loose or improperly crimped lugs in certain electrical panel locations and replacement if necessary, and inspection for foreign object damage in certain areas and removal if necessary. We are issuing this AD to prevent arcing, damage to adjacent structure, smoke in the cockpit, or loss of system redundancies.
Airworthiness Directives; Learjet Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Learjet Inc. Model 60 airplanes. This AD was prompted by two incidents of swapped fire extinguishing wires. This AD requires inspecting the electrical leads routed to the fire extinguishing containers for proper identification and missing labels, and to ensure the electrical leads are connected to the correct squibs; and corrective actions if necessary. We are issuing this AD to prevent the extinguishing agent of the fire extinguishing container from being delivered to the wrong engine in the event of an engine fire, and a consequent uncontrolled fire.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Airplanes
We are superseding an existing airworthiness directive (AD) for all EMBRAER Model ERJ 170 airplanes. That AD currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to incorporate new structural inspection requirements. Since we issued that AD, during full scale fatigue testing, cracks were found in certain structural components of the airplane. Analysis of these cracks resulted in the manufacturer modifying the ALS of EMBRAER 170 Maintenance Review Board Report (MRBR), to include new inspections tasks, or modifying the current tasks and their respective thresholds and intervals. This new AD requires revising the maintenance program to incorporate new or revised structural inspection requirements. We are issuing this AD to detect and correct fatigue cracking which could result in the loss of structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200 and -300 series airplanes. This AD was prompted by reports of two failures of the single-tabbed bracket on the rudder. This AD requires replacing certain single-tabbed bonding brackets in the airplane empennage with two-tabbed bonding brackets. This AD also requires, for certain airplanes, installing new bonding jumpers, and measuring the resistance of the modified installation to verify resistance is within specified limits. We are issuing this AD to prevent failure of the bonding jumper bracket, which could result in loss of lightning protection ground path, which could lead to increased lightning-induced currents and subsequent damage to composite structures, hydraulic tubes, and actuator control electronics. In the event of a lightning strike, loss of lightning ground protection could result in the loss of control of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by test reports that showed that failure of a retract port flexible hose of a main landing gear (MLG) retraction actuator could cause excessive hydraulic fluid leakage. This AD requires a detailed inspection for defects and damage of the retract port flexible hose on the left and right MLG retraction actuator and replacement of the flexible hose if needed. We are issuing this AD to detect and correct defects and damage of the retract port flexible hose which could lead to an undamped extension of the MLG and could result in MLG structural failure, leading to an unsafe asymmetric landing configuration.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. This AD was prompted by reports of cracks found in the Web pockets of the wing center section (WCS) spanwise beams. This AD requires repetitive detailed inspections and high frequency eddy current inspections for cracks of the WCS spanwise beams, and repair if necessary. We are issuing this AD to detect and correct cracking in the WCS spanwise beams, which could result in reduced structural integrity of the wings.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes.
