Commercial and Industrial Fans and Blowers: This rulemaking includes a proposal for a test procedure, reporting requirements, and labelling requirements for certain fans and blowers. (...)

Amendment establishing phytosanitary requirements governing the importation of pollen of the indicated species.
Based on the pest risk analysis (PRA) for the quarantine pest Erwinia amylovora, absent from Chile, phytosanitary requirements have been established which govern the importation into Chile of pollen of the species indicated in the draft resolution.

It is also stipulated that:
• (...);
• The importer must declare the genetic status of materials genetically modified by modern technology and comply with SAG regulations establishing requirements for the importation and introduction into the environment of these types of material.

In this document, the U.S. Department of Energy ("DOE" or the "Department") is proposing amended energy conservation standards for variable refrigerant flow (VRF) multi-split air conditioners and VRF multi-split system heat pumps (collectively referred to as "VRF multi-split systems") that rely on a new cooling efficiency metric and are equivalent to those levels specified in the industry standard. DOE has preliminarily determined that it lacks the clear and convincing evidence required by the statute to adopt standards more stringent than the levels specified in the industry standard. (...)

Energy Conservation Program: Test Procedure for Commercial Warm Air Furnaces: The U.S. Department of Energy ("DOE") proposes to amend the test procedures for commercial warm air furnaces ("CWAFs") to incorporate the latest versions of the industry standards that are currently incorporated by reference. DOE also proposes to establish a new metric, Thermal Efficiency Two ("TE2"), and corresponding test procedure. Use of the newly proposed test procedure would become mandatory at such time as compliance with amended energy conservation standards based on TE2 is required, should DOE adopt such standards. (...)

National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Utility Steam Generating Units--Revocation of the 2020 Reconsideration, and Affirmation of the Appropriate and Necessary Supplemental Finding: The Environmental Protection Agency (EPA) is proposing to revoke a 22 May 2020 finding that it is not appropriate and necessary to regulate coal- and oil-fired electric utility steam generating units (EGUs) under Clean Air Act (CAA) section 112, and to reaffirm the Agency's 25 April 2016 finding that it remains appropriate and necessary to regulate hazardous air pollutant (HAP) emissions from EGUs after considering cost. The Agency is also reviewing another part of the 22 May 2020 action, a residual risk and technology review (RTR) of Mercury and Air Toxics Standards (MATS). (...)

Energy Conservation Program: Proposed Determination of Portable Electric Spas as a Covered Consumer Product: The U.S. Department of Energy ("DOE") has tentatively determined that portable electric spas qualify as a covered product under Part A of Title III of the Energy Policy and Conservation Act, as amended ("EPCA"). DOE has tentatively determined that coverage of portable electric spas is necessary and appropriate to carry out the purposes of EPCA and that the average U.S. household energy use for portable electric spas is likely to exceed 100 kilowatt-hours per year. If, after public comment, DOE issues a final determination of coverage for this product, DOE may prescribe both test procedures and energy conservation standards for this product. DOE will publish a final decision on coverage as a separate notice, which is an action that will be completed prior to the initiation of any test procedure or energy conservation standards rulemaking. If DOE determines that coverage is warranted, DOE will proceed with its typical rulemaking process for both test procedures and standards. DOE is not proposing test procedures or energy conservation standards as part of this proposed determination. If DOE proceeds with a rulemaking to establish energy conservation standards, DOE would determine if portable electric spas satisfy the provisions of 42 U.S.C. 6295(l)(1) during the course of that rulemaking.

Energy Conservation Program: Test Procedure for Computer Room Air Conditioners: The U.S. Department of Energy (DOE or the Department) proposes to amend its test procedure for computer room air conditioners (CRACs) to incorporate by reference the latest draft version of the relevant industry consensus test standard. DOE also proposes to adopt the net sensible coefficient of performance (NSenCOP) metric in its test procedures for CRACs. Additionally, DOE proposes to amend certain provisions for representations and enforcement. (...)

Energy Conservation Program: Proposed Determination of Miscellaneous Gas Products as a Covered Consumer Product: The U.S. Department of Energy ("DOE") has tentatively determined that miscellaneous gas products, which are comprised of decorative hearths and outdoor heaters, qualify as covered products under Part A of Title III of the Energy Policy and Conservation Act, as amended ("EPCA"). DOE has tentatively determined that coverage of miscellaneous gas products is necessary and appropriate to carry out the purposes of EPCA, and that the average U.S. household energy use for miscellaneous gas products is likely to exceed 100 kilowatt-hours per year.

The Environmental Protection Agency (EPA) is proposing particulate matter (PM) emission standards and test procedures applicable to certain classes of engines used by civil subsonic jet airplanes (those engines with rated output of greater than 26.7 kilonewtons (kN)) to replace the existing smoke standard for aircraft. These proposed standards and test procedures are equivalent to the engine standards adopted by the United Nations' International Civil Aviation Organization (ICAO) in 2017 and 2020 and would apply to both new type design aircraft engines and in-production aircraft engines. The EPA, as well as the United States Federal Aviation Administration (FAA), actively participated in the ICAO proceedings in which these requirements were developed. These proposed standards would reflect the importance of the control of PM emissions and U.S. efforts to secure the highest practicable degree of uniformity in aviation regulations and standards. (...) As part of this update, the EPA is also proposing to align with ICAO by applying the smoke number standards to engines less than or equal to 26.7 kilonewtons rated output used in supersonic airplanes.

In this notice of proposed rulemaking (NOPR), DOE proposes to establish new energy conservation standards for dehumidifying direct-expansion dedicated outdoor air systems (DX-DOASes) that are of equivalent stringency as the minimum levels specified in the amended American Society of Heating, Refrigerating and Air-Conditioning Engineers ("ASHRAE") Standard 90.1 "Energy Standard for Buildings Except Low-Rise Residential Buildings" ("ASHRAE Standard 90.1") when tested pursuant to the most recent applicable industry standard for this equipment.
