⚖️EPA Proposes Regulation for C.I. Pigment

The Environmental Protection Agency (EPA or Agency) is proposing to address the unreasonable risk of injury to human health presented by C.I. Pigment Violet 29 (CASRN 81-33-4, also known as PV29), under its conditions of use as documented in EPA's January 2021 Risk Evaluation for PV29 and the September 2022 Revised Risk Determination for PV29 prepared under TSCA. TSCA requires that EPA address by rule any unreasonable risk of injury to health or the environment identified in a TSCA risk evaluation and apply requirements to the extent necessary so the chemical no longer presents unreasonable risk. To address the identified unreasonable risk, EPA is proposing requirements to protect workers from the unreasonable risk of PV29 during manufacturing and processing, certain industrial and commercial uses of the chemical, and disposal, while also allowing for a reasonable transition period prior to enforcement of said requirements.

🌍Air Quality Regulation Updates for Maricopa County Businesses

The Environmental Protection Agency (EPA) is finalizing a limited approval and limited disapproval of revisions to the Maricopa County Air Quality Department (MCAQD or "County") portion of the Arizona State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) from loading of organic liquids and gasoline. Under the authority of the Clean Air Act (CAA or "Act"), this action simultaneously approves local rules that regulate these emission sources and directs Arizona to correct rule deficiencies. We are also finalizing a disapproval of MCAQD's reasonably available control technology (RACT) demonstration for the source categories associated with these rules for the 2008 8-hour ozone national ambient air quality standard (NAAQS) in the Phoenix-Mesa ozone nonattainment area.

💧Federal Water Quality Standards Withdrawal

The Environmental Protection Agency (the EPA or agency) is withdrawing the proposed rule entitled "Federal Baseline Water Quality Standards for Indian Reservations," which published in the Federal Register on May 5, 2023. The EPA is electing to withdraw and not finalize the proposed rule at this time. Instead, the EPA intends to focus the agency's resources on engaging with Tribes to support Tribes' efforts to seek authority to administer their own water quality standards (WQS) program under the Clean Water Act's provision for eligible Tribes to be treated in a similar manner as states (TAS). The EPA will continue to work closely with, and offer support to, Tribes that are interested in pursuing TAS to administer a WQS program and developing their own WQS under the Clean Water Act.

Alaska's submission includes SIP revisions to meet nonattainment planning requirements for emissions inventories, modeling and sulfur dioxide precursor demonstration for major stationary sources, control measures, attainment projections and progress to attainment and associated motor vehicle emissions budgets, and contingency measures. The EPA is also starting the adequacy process for the budgets.
