Environmental Protection Agency November 24, 2021 – Federal Register Recent Federal Regulation Documents

The Arkansas Department of Energy and Environment, Division of Environmental Quality (DEQ) has submitted a request to update the delegation and approval of its program for the implementation and enforcement of certain National Emission Standards for Hazardous Air Pollutants (NESHAP) promulgated under the Clean Air Act (CAA), as provided for under the delegation mechanism previously approved by the Environmental Protection Agency (EPA). The EPA is proposing to approve DEQ's requested update of its NESHAP delegation. If finalized as proposed, the delegation will only encompass sources subject to one or more Federal section 112 standards which are also subject to the requirements of the Title V operating permits program.

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) and are also subject to Orders issued by EPA pursuant to TSCA. 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.
