We, the U.S. Fish and Wildlife Service (Service), are removing the Florida golden aster (Chrysopsis floridana), a short-lived perennial, from the Federal List of Endangered and Threatened Plants (List) due to recovery. Our review indicates that the threats to the species have been eliminated or reduced to the point that the species has recovered and no longer meets the definition of an endangered or threatened species under the Endangered Species Act of 1973, as amended (Act). Accordingly, the prohibitions and conservation measures provided by the Act will no longer apply to this species.

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by a determination that a certain nondestructive test (NDT) procedure associated with a certain airworthiness limitation for inspecting the inboard, mid, and outboard flap metallic end ribs does not contain all of the necessary instructions. This AD requires a revision to the existing maintenance or inspection program to require using a revised NDT procedure when performing an airworthiness limitation task. This AD also prohibits the use of earlier revisions of that NDT procedure. The FAA is issuing this AD to address the unsafe condition on these products.

This action amends the Cincinnati/Northern Kentucky International Airport, KY, Class B airspace area description by making editorial changes to three sub-area shelf boundaries of the Class B airspace from using the Cincinnati, KY, Very High Frequency Omnidirectional Range/Tactical Air Navigation (VORTAC) to a reference point. The reference point uses the same geographic coordinates as the Cincinnati VORTAC location listed in the existing description. Additionally, this action also removes the airport name from the airspace designation to comply with FAA regulatory guidance, updates the Airport Reference Point (ARP) geographic coordinates for the Cincinnati/Northern Kentucky International Airport to match the FAA National Airspace System Resource (NASR) database, and changes the Class B airspace center point from the Cincinnati/Northern Kentucky International Airport to ``Point of Origin''. The point of origin uses the same geographic coordinates as the Cincinnati/Northern Kentucky International Airport listed in the existing description. Finally, this action makes minor edits to the sub-area descriptions for clarity and readability. These changes are editorial only and do not alter the current boundaries, altitudes, ATC procedures, or operating requirements for the Cincinnati/Northern Kentucky International Airport Class B airspace.

The FAA is adopting a new airworthiness directive (AD) for certain Austro Engine GmbH Model E4 and E4P engines. This AD was prompted by reports of engine failures and the determination that certain batches of cap screws, installed on the inner main bearing positions of the engine, were manufactured at the lower end of the material strength tolerance. This AD requires replacing certain cap screws with a part eligible for installation and prohibits installing certain cap screws on any inner main bearing position of any engine. This AD also prohibits installing certain engine cores on any engine unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.

In accordance with the regulations implementing the Atlantic Herring Fishery Management Plan, this action adjusts the 2024 harvest specifications for the herring fishery.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T2, EC135T3, and EC635T2+ helicopters. This AD was prompted by a report of a separated tail rotor (T/R) blade due to a crack which was caused by intergranular corrosion. This AD requires repetitively inspecting certain part- numbered T/R blades for a crack and, depending on the results, removing any cracked T/R blade from service. This AD also prohibits installing certain T/R blades on any helicopter unless certain requirements are met. These actions are specified in a European Union Aviation Safety Agency (EASA) emergency AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The Federal Communications Commission is correcting the docket numbers for commenters under the preamble section titled, ADDRESSES, of the proposed rule that appeared in the Federal Register on February 26, 2024.

The United States Patent and Trademark Office (Office or USPTO) proposes to update its rules governing amendment practice in trial proceedings under the Leahy-Smith America Invents Act (AIA) to make permanent certain provisions of the Office's motion to amend pilot program (MTA pilot program) and to revise the rules that allocate burdens of persuasion in connection with motions to amend (MTAs). The Office proposes to revise its rules of practice to provide for issuance of preliminary guidance in response to an MTA and to provide a patent owner with the option for filing one additional revised MTA. Further, the Office proposes to revise the rules to clarify that a preponderance of evidence standard applies to any new ground of unpatentability raised by the Board and to clarify that when exercising the discretion to grant or deny an MTA or to raise a new ground of unpatentability, the Board may consider all evidence of record in the proceeding, including evidence identified through a prior art search conducted by the Office at the Board's request and added to the record. These rules better ensure the Office's role of issuing robust and reliable patents, and the predictability and certainty of post-grant trial proceedings before the Board. These changes would apply to the existing consolidated set of rules relating to the Office trial practice for inter partes review (IPR), post-grant review (PGR), and derivation proceedings that implemented provisions of the AIA providing for trials before the Office.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations for certain brake accumulators are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This proposed AD would also require determining the accumulated landings on the affected brake accumulators. The FAA is proposing this AD to address the unsafe condition on these products.

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This regulation establishes exemptions from the requirement of a tolerance for residues of various fragrance components listed in Unit II of this document when they are used as inert ingredients in antimicrobial formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils when the end-use concentration does not exceed 100 parts per million (ppm). Innovative Reform Group, on behalf of The Clorox Company, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of various fragrance components, when used in accordance with the terms of those exemptions.

The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the State of Delaware into Delaware's existing SIP-approved public notice requirements for certain permits authorized under Delaware regulation 1102. The revisions Delaware made to its underlying regulation standardize the public notices requirements across various permits under Delaware regulation 1102 to be consistent with EPA's October 18, 2016 final rule amendments to the notice and comment requirements for Title V, new source review and outer continental shelf (OCS) permit programs. This action is being taken under the Clean Air Act (CAA).

On April 14, 2023, the Commodity Futures Trading Commission (Commission or CFTC) published a notice of proposed rulemaking (First Proposal) that proposed to amend the derivatives clearing organization (DCO) risk management regulations adopted under the Commodity Exchange Act (CEA) to permit futures commission merchants (FCMs) that are clearing members of DCOs (clearing FCMs), subject to specified requirements, to treat separate accounts of a single customer as accounts of separate legal entities for purposes of certain Commission regulations. In light of comments received supporting direct application of separate account treatment requirements to FCMs in the Commission's regulations, the Commission has determined to withdraw the First Proposal. The Commission now proposes regulations to require an FCM to ensure that a customer does not withdraw funds from its account with the FCM if the balance in such account after such withdrawal would be insufficient to meet the customer's initial margin requirements, and relatedly, to permit an FCM, in certain circumstances and subject to certain conditions, to treat the separate accounts of a single customer as accounts of separate entities for purposes of certain Commission regulations (Second Proposal). The proposed amendments would establish the conditions under which an FCM may engage in such separate account treatment.

The Environmental Protection Agency (EPA) is taking final action to approve portions of two State implementation plan (SIP) revisions submitted by the State of California to meet Clean Air Act (CAA) requirements for the 2008 8-hour ozone national ambient air quality standards (NAAQS or ``standards'') and the 2015 8-hour ozone NAAQS in the San Diego County ozone nonattainment area (``San Diego County area'' or ``area''). The first SIP revision, ``2020 Plan for Attaining the National Ambient Air Quality Standards for Ozone in San Diego County'' (``2020 San Diego County Ozone SIP'' or ``2020 Plan''), addresses most of the SIP requirements for the area. The second SIP revision, referred to as the ``Smog Check Certification,'' supplements the motor vehicle inspection and maintenance program portion of the 2020 Plan. The EPA is taking final action to approve the 2020 Plan, and the San Diego County area portion of the Smog Check Certification, as meeting all the applicable ozone nonattainment area requirements for the 2008 and 2015 8-hour ozone NAAQS addressed by the plan except for the emissions statement requirement that the EPA previously found to have been met and the contingency measure requirements, for which the EPA is deferring action.
