Proposed rule - This action proposes reconsideration amendments to the new source performance standards (NSPS) . These amendments, if finalized, would remove sources in the transmission and storage segment from the source category, rescind the NSPS (including both the volatile organic compounds (VOC) and methane requirements) applicable to those sources, and rescind the methane-specific requirements (the "methane requirements") of the NSPS applicable to sources in the production and processing segments. The U.S. Environmental Protection Agency (EPA) is also proposing, as an alternative, to rescind the methane requirements of the NSPS applicable to all oil and natural gas sources, without removing any sources from the source category. Furthermore, the EPA is taking comment on alternative interpretations of its statutory authority to regulate pollutants under the Clean Air Act (CAA), and associated record and policy questions.

Proposed rule - The U.S. Environmental Protection Agency (EPA) is proposing the results of a residual risk and technology review (RTR) of the National Emission Standards for Hazardous Air Pollutants for Miscellaneous Coating Manufacturing (MCM NESHAP) facilities, as required by the Clean Air Act (CAA) . The EPA is proposing to find risks due to emissions of air toxics to be acceptable from the MCM source category and to determine that the current NESHAP provides an ample margin of safety to protect public health. The EPA identified no new cost-effective controls under the technology review to achieve further emissions reductions from process units subject to standards under the NESHAP. The EPA is also proposing revisions related to emissions during periods of startup, shutdown, and malfunction (SSM), including clarifying regulatory provisions for certain vent control bypasses; provisions for electronic reporting of performance test results, performance evaluation reports, compliance reports, and Notification of Compliance Status (NOCS) reports; and provisions to conduct periodic performance testing of oxidizers used to reduce emissions of organic hazardous air pollutants (HAP) .

Proposed rule - The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Plywood and Composite Wood Products (PCWP) to address the results of the residual risk and technology review (RTR) that the EPA is required to conduct under the Clean Air Act (CAA) . The EPA is proposing to amend provisions addressing periods of startup, shutdown and malfunction (SSM); add provisions regarding electronic reporting; add repeat emissions testing requirements; and make technical and editorial changes. The EPA is proposing these amendments to improve the effectiveness of the NESHAP. While the proposed amendments would not result in reductions in emissions of hazardous air pollutants (HAP), this action, if finalized, would result in improved monitoring, compliance, and implementation of the rule.

The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Cellulose Products Manufacturing to address the results of the residual risk and technology review (RTR) that the EPA is required to conduct under the Clean Air Act (CAA) . The EPA is proposing to amend provisions addressing periods of startup, shutdown, and malfunction (SSM); to add provisions regarding periodic emissions testing and electronic reporting; to provide more flexibility for monitoring requirements; and to make technical and editorial changes. While the proposed amendments would not result in reductions in emissions of hazardous air pollutants (HAP), this action, if finalized, would result in improved monitoring, compliance, and implementation of the rule.

Proposed rule - The U.S. Environmental Protection Agency (EPA) is conducting the residual risk and technology review (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Paper and Other Web Coating (POWC) source category that is required under the Clean Air Act (CAA) . We are proposing to find the risks due to emissions of air toxics to be acceptable from this source category and that the current NESHAP provides an ample margin of safety to protect public health. Further, we identified no new cost-effective controls under the technology review that would achieve significant further emissions reductions, and, thus, are proposing to find that no revisions are necessary based on developments in practices, processes, or control technologies. In addition to performing the RTR, we are proposing certain amendments to the POWC NESHAP. Specifically, the EPA is proposing to add a compliance demonstration equation that accounts for retained volatiles in the web coating; to amend provisions addressing periods of startup, shutdown, and malfunction (SSM); to add repeat testing and electronic reporting requirements; and to make technical and editorial changes. The EPA is proposing these amendments to improve the effectiveness of the NESHAP.

2019 Sunset Review and substance renewals - This document announces the renewal of substance exemptions as listed on the National List of Allowed and Prohibited Substances (National List) within the U.S. Department of Agriculture's (USDA) organic regulations. This document reflects the outcome of the 2019 sunset review process and addresses recommendations submitted to the Secretary of Agriculture (Secretary), through the USDA's Agricultural Marketing Service (AMS), by the National Organic Standards Board (NOSB).

Proposed Rule - EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for seven 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 seven 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, and EPA has conducted a review of the notice, made an appropriate determination on the notice under TSCA and has taken any risk management actions as are required as a result of that determination.

Proposed rule - EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 31 chemical substances which were the subject of premanufacture notices (PMNs) . Eight of these chemical substances are subject to TSCA Orders issued by EPA and the remaining 23 of these chemical substances received a "not likely to present an unreasonable risk" determination. This action would require persons who intend to manufacture (defined by statute to include import) or process any of these 31 chemical substances for an activity that is proposed as a significant new use to notify EPA at least 90 days before commencing that activity. 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.

Proposed rule - This proposed rule would amend the National List of Allowed and Prohibited Substances (National List) section of the United States Department of Agriculture's (USDA's) organic regulations to implement recommendations submitted to the Secretary of Agriculture (Secretary) by the National Organic Standards Board (NOSB) . This rule proposes to add blood meal, made with sodium citrate, to the National List as a soil fertilizer in organic crop production; add natamycin to the National List to prohibit its use in organic crop production; and add tamarind seed gum as a non-organic agricultural substance for use in organic handling when organic forms of tamarind seed gum are not commercially available.

Proposed rule - EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 26 chemical substances which were the subject of premanufacture notices (PMNs) . Five of these chemical substances are subject to Orders issued by EPA pursuant to TSCA, and the remaining 21 of these chemical substances received a "not likely to present an unreasonable risk" determination pursuant to TSCA. This action would require persons who intend to manufacture (defined by statute to include import) or process any of these 26 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 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.
