Environmental Protection Agency June 7, 2021 – Federal Register Recent Federal Regulation Documents

This regulation establishes an exemption from the requirement of a tolerance for residues of cellulose, ethyl ether; number average molecular weight 13,000 Daltons when used as an inert ingredient in a pesticide chemical formulation. Exponent, Inc. on behalf of Nutrition & Biosciences USA 1, LLC, formerly DDP Specialty Electronic Materials US, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of cellulose, ethyl ether on food or feed commodities.

EPA is amending significant new use rules (SNURs) issued under the Toxic Substances Control Act (TSCA) for certain chemical substances identified herein, which were the subject of premanufacture notices (PMNs) and significant new use notices (SNUNs). This action would amend the SNURs to allow certain new uses reported in the SNUNs without additional notification requirements and modify the significant new use notification requirements based on the actions and determinations for the SNUN submissions. EPA is issuing these amendments based on review of new and existing data for the chemical substances.

EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances which were the subject of premanufacture notices (PMNs). This action requires 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 rule. This action further requires that persons not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice (SNUN), 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.

In the Rules and Regulations section of this Federal Register, the Environmental Protection Agency (EPA) is granting a request by the California Air Resources Board (CARB or ``State'') to voluntarily reclassify the Eastern Kern nonattainment area (``Eastern Kern'') from ``Serious'' to ``Severe'' for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS) under section 181(b)(3) of the Clean Air Act (CAA). In this action, the EPA is proposing a schedule for the State to submit revisions to the state implementation plan (SIP) addressing Severe area requirements and to submit revisions to the title V operating permit rules for this area. Under the EPA's proposed schedule, California would be required to submit SIP revisions addressing Severe area requirements for Eastern Kern, including revisions to New Source Review (NSR) rules, no later than 18 months from the effective date of the EPA's final rule reclassifying Eastern Kern to Severe. Submittal of any corresponding revisions to the title V rules that apply in Eastern Kern would be due within six months of the effective date of the reclassification. Lastly, the EPA is proposing a deadline for implementation of new Reasonably Available Control Technology (RACT) rules as expeditiously as practicable but no later than 18 months from the date when the Severe area RACT SIP will be due.

The Environmental Protection Agency (EPA) (also, ``the Agency'' or ``we'' in this preamble) is proposing technical amendments to an existing exclusion from the list of federal hazardous waste (delisting) issued to the United States Department of Energy (Energy) under the Resource Conservation and Recovery Act. These modifications address changes to the 200-Area Effluent Treatment System associated with the delisting necessary to accept liquid effluents expected to be generated from vitrification of certain low-activity mixed wastes at the Hanford Federal Facility, or Hanford Site, in Richland, Washington.
