EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 28 chemical substances which were the subject of premanufacture notices (PMNs) . The chemical substances are subject to Orders issued by EPA pursuant to section 5(e) of TSCA. This action would require persons who intend to manufacture (defined by statute to include import) or process any of these 28 chemical substances for an activity that is proposed as a significant new use to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the intended use 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 with that determination.

The EPA is proposing regulatory changes to allow gasoline blended with up to 15 percent ethanol to take advantage of the 1-pound per square inch (psi) Reid Vapor Pressure (RVP) waiver that currently applies to E10 during the summer months. EPA is also proposing an interpretive rulemaking which defines gasoline blended with up to 15 percent ethanol as "substantially similar" to the fuel used to certify Tier 3 motor vehicles. Finally, EPA is proposing regulatory changes to modify certain elements of the Renewable Fuel Standard (RFS) compliance system, in order to improve functioning of the renewable identification number (RIN) market and prevent market manipulation.

Architectural and industrial maintenance (AIM) coatings, commonly referred to as paints, release volatile organic compounds (VOCs) into the atmosphere. VOC content is regulated in Part 205 for 52 coating categories. The major revisions to this proposal are to reduce the VOC limit on 12 coating categories, create VOC limits for 12 additional coating categories, eliminate 15 coating categories and eliminate the quart exemption. This proposal applies to any person who supplies, sells, offers for sale or manufactures architectural coatings for use in the State of New York.

Amends rules to reduce exhaust and evaporative emissions from off-highway recreational vehicles.

HUD proposes to implement the Formaldehyde Standards for Composite Wood Products Act of 2010, which added Title VI to the Toxic Substances Control Act (TSCA) . In addition, HUD proposes to remove certain aspects of HUD's current manufactured housing formaldehyde standards requirements that are not addressed by TSCA, including provisions for a health notice to be posted in every manufactured home, testing of post-treatment panels after certification, and testing of certain plywood materials.

Under the Toxic Substances Control Act (TSCA), EPA has the authority to apply a suite of regulatory tools to address unreasonable risks from chemical substances, including authority to regulate the distribution in commerce for a particular use and to regulate any manner or method of commercial use, to the extent necessary so that the chemical substance no longer presents unreasonable risk. EPA is issuing an advance notice of proposed rulemaking (ANPRM) to solicit public input on training, certification, and limited access requirements that could address any unreasonable risks that EPA could potentially find to be presented by methylene chloride when used for commercial paint and coating removal. Such a program could allow access to paint and coating removal products containing methylene chloride only to commercial users who are certified as properly trained to engage in use practices that do not present unreasonable risks.

The Environmental Protection Agency (EPA) is proposing amendments to the rulemaking titled "Standards of Performance for Greenhouse Gas Emissions from New, Modified, and Reconstructed Stationary Sources: Electric Utility Generating Units (EGUs)," which the EPA promulgated by notice dated 23 October 2015 (i.e., the 2015 Rule) . Specifically, the EPA proposes to amend its previous determination that the best system of emission reduction (BSER) for newly constructed coal-fired steam generating units (i.e., EGUs) is partial carbon capture and storage (CCS) . Instead, the EPA proposes to find that the BSER for this source category is the most efficient demonstrated steam cycle (e.g., supercritical steam conditions for large units and subcritical steam conditions for small units) in combination with the best operating practices. The EPA proposes to revise the standard of performance for newly constructed steam generating units as separate standards of performance for large and small steam generating units that reflect the Agency's amended BSER determination. In addition, the EPA proposes to revise the standard of performance for reconstructed steam generating units to be separate standards of performance for reconstructed large and small steam generating units, consistent with the proposed revised standards for newly constructed steam generating units. The EPA also proposes separate standards of performance for newly constructed and reconstructed coal refuse-fired EGUs. In addition, the EPA proposes to revise the maximally stringent standards for large modifications of steam generating units to be consistent with the standards for reconstructed large and small steam generating units. The EPA is not proposing to amend and is not reopening the standards of performance for newly constructed or reconstructed stationary combustion turbines. The EPA is also proposing to make other miscellaneous technical changes in the regulatory requirements.

The U.S. Department of Energy (DOE) is initiating a data and information collection process through this request for information to better understand whether there are provisions in the Department's test procedures for consumer appliances and industrial equipment that could be improved to produce results that are more representative of average use cycles or periods of use. Over time, many of DOE's test procedures have been amended to account for products' increased functionality and modes of operation. DOE's intent in issuing this RFI is to gather information to ensure that the inclusion of measurement provisions in its test procedures associated with such increased functionality has not inadvertently compromised the measurement of representative average use cycles or periods of use, and made some test procedures unnecessarily burdensome. DOE welcomes written comments from the public on any subject within the scope of this document, including topics not directly outlined in this RFI. DOE particularly welcomes comments on any suggestions for reducing or avoiding regulatory burdens within the context of measuring average use cycles or periods of use.

The Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Stationary Combustion Turbines to address the results of the residual risk and technology review (RTR) the EPA is required to conduct in accordance with the Clean Air Act (CAA) . The EPA is proposing to find that the risks from this source category due to emissions of air toxics are acceptable and that the existing NESHAP provides an ample margin of safety to protect public health. The EPA identified no new cost-effective controls under the technology review that would achieve further emissions reductions from the source category. The EPA is also proposing to amend provisions addressing periods of startup, shutdown, and malfunction (SSM) and to require electronic reporting. In addition, the EPA is proposing to remove the stay of the effectiveness of the standards for new lean premix and diffusion flame gas-fired turbines that was promulgated in 2004.

EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 11 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 11 chemical substances for an activity that is designated as a significant new use by this proposed rule. If this proposed rule is made final, persons may not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice, and EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken any actions as are required as a result of that determination.
