Significant New Use Rules on Certain Chemical Substances (20-2.5e).

Proposed rule - EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMNs) . The SNURs require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the use, under the conditions of use for that chemical substance, within the applicable review period. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required by that determination.

Energy Conservation Program for Appliance Standards: Energy Conservation Standards for Residential Furnaces and Commercial Water Heaters.

In response to a petition for rulemaking submitted on 18 October 2018 (Gas Industry Petition), the Department of Energy (DOE) published that petition in the Federal Register on 1 November 2018, for public review and input, and DOE subsequently published a proposed interpretive rule in the Federal Register on 11 July 2019, which tentatively determined that in the context of residential furnaces, commercial water heaters and similarly-situated products/equipment, use of non-condensing technology (and associated venting) may constitute a performance-related "feature" under the Energy Policy and Conservation Act (EPCA) that cannot be eliminated through adoption of an energy conservation standard. After carefully considering the public comments on its proposed interpretive rule, DOE has tentatively determined to consider a more involved class structure which turns on maintenance of compatibility with existing venting categories, and the Department seeks further information on the potential feasibility, burdens, and other implications of implementing such a venting- compatibility approach. DOE requests comments limited in scope to this issue, after which DOE will respond to not only this matter, but also to all of the other topics raised in comments on the July 2019 notice of proposed interpretive rule.

Computer and Monitor Regulations.

Proposed rule - The broad objective of this rulemaking is to update the Appliance Efficiency Regulations to modify and clarify existing standards and test procedures for computers and computer monitors to incorporate new technologies and innovations.

Significant New Use Rules on Certain Chemical Substances (20-9.B).

Proposed rule - EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances which are the subject of premanufacture notices (PMNs) . This action would require persons to notify EPA at least 90 days before commencing manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use by this proposed rule. This action would further require that persons not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice (SNUN), and EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken any risk management actions as are required as a result of that determination.

Energy Conservation Program: Energy Conservation Standards for Computer Room Air Conditioners and Air-Cooled, Three-Phase, Small Commercial Package Air Conditioning and Heating Equipment With a Cooling Capacity of Less Than 65,000 Btu/h.

The U.S. Department of Energy (DOE) is publishing an analysis of the energy saving s potential of amended industry consensus standards for certain classes of computer room air conditioners (CRACs) and air- cooled, three-phase, small commercial package air conditioning and heating equipment with a cooling capacity of less than 65,000 Btu/h (air-cooled, three-phase, small commercial package AC and HP (<65 K) equipment) . As required under the Energy Policy and Conservation Act (EPCA), DOE has been triggered to act by changes to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 90.1. DOE is also soliciting information regarding energy conservation standards for CRACs and air-cooled, three-phase, small commercial package AC and HP (<65 K) equipment for which the industry consensus standards have not been amended, pursuant to EPCA's six-year-lookback review requirement. This notice of data availability (NODA) and request for information (RFI) solicits information from the public to help DOE determine whether more-stringent amended standards for CRACs or air-cooled, three-phase, small commercial package AC and HP (<65 K) equipment would result in significant additional energy saving s and whether such standards would be technologically feasible and economically justified. DOE welcomes written comments from the public on any subject within the scope of this document (including topics not specifically raised in this NODA/RFI), as well as the submission of data and other relevant information.

Significant New Use Rules on Certain Chemical Substances (20-10.B).

Proposed rule - EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances which are the subject of premanufacture notices (PMNs) . This action would require persons to notify EPA at least 90 days before commencing manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use by this proposed rule. This action would further require that persons not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice (SNUN), and EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken any risk management actions as are required as a result of that determination.

Vessel Incidental Discharge National Standards of Performance.

The U.S. Environmental Protection Agency (EPA) is publishing for public comment a proposed rule under the Vessel Incidental Discharge Act that would establish national standards of performance for marine pollution control devices for discharges incidental to the normal operation of primarily non-military and non-recreational vessels 79 feet in length and above into the waters of the United States or the waters of the contiguous zone. The proposed national standards of performance were developed in coordination with the U.S. Coast Guard (USCG) and in consultation with interested Governors. The proposed standards, once finalized and implemented through corresponding USCG regulations addressing implementation, compliance, and enforcement, would reduce the discharge of pollutants from vessels and streamline the current patchwork of federal, state, and local vessel discharge requirements. Additionally, EPA is proposing procedures for states to follow if they choose to petition EPA to issue an emergency order, to review any standard of performance, regulation, or policy, to request additional requirements with respect to discharges in the Great Lakes, or to apply to EPA to prohibit one or more types of vessel discharges proposed for regulation in this rulemaking into specified waters to provide greater environmental protection.

Self-Contained Lighting Controls.

Proposed rule - Provides updates to the Appliance Efficiency Regulations. This includes the repeal of the self-contained lighting control requirements, updates to reflect current federal laws, modifications to data submittal requirements for certain appliances, the removal of the outdated minimum lumen output requirement for portable luminaires, and non-substantive changes for clarity and consistency.

Prohibition on Certain Hydrofluorocarbons in Stationary Refrigeration, Chillers, Aerosols-Propellants, and Foam End-Uses Regulation.

Proposed rule - In this rulemaking, the California Air Resources Board (CARB) proposes to address emissions from refrigerants in stationary refrigeration and air conditioning (AC) equipment by amending the existing California Hydrofluorocarbon (HFC) Regulation (hereinafter "Proposed Amendments") to (1) impose further limits on HFCs used in non-residential (e.g. commercial) stationary refrigeration equipment, and (2) to regulate new AC equipment used for both residential and non-residential purposes.
