The EPA is proposing to improve protection of public health and recover valuable energy and mineral resources by designating scrap tires, including previously abandoned scrap tires, that are combusted in cement kilns, as non-waste fuel. In addition, the EPA is proposing to revise the definition of established tire collection program to include abandoned scrap tires that are recovered for use as fuel so they can be managed the same as collected scrap tires. These proposed regulatory changes support several goals of the Resource Conservation and Recovery Act (RCRA) by facilitating the use of abandoned scrap tires as a non-waste fuel and ingredient in Portland cement manufacturing while simultaneously reducing risks to human health and addressing environmental harms caused by tire piles. These proposed revisions are amendments to the Non-Hazardous Secondary Materials (NHSM) regulations, which establish standards and procedures for identifying whether non-hazardous secondary materials are solid wastes when legitimately used as fuels or ingredients in combustion units.

Hardwood tree species are widely distributed across the southeastern United States and provide significant economic and ecological benefits. Hardwood forests support wildlife habitat, contribute to food resources, nutrient cycling, offer recreational opportunities, and supply valuable timber. However, many hardwood species are susceptible to diseases that produce symptomatic leaves such as bacterial leaf scorch, anthracnose, and others that can reduce aesthetic value and overall tree health. Accurate identification of these diseases is essential for effective management. In this webinar the presenter will discuss the biology, symptoms, impacts, and management strategies for several common hardwood tree diseases with foliar symptoms.

EPA is finalizing new source performance standards (NSPS) and emission guidelines (EG) for large municipal waste combustors (MWC).

The Environmental Protection Agency (EPA) is proposing to delay the compliance date for Facility Response Plan (FRP) requirements as well as to make language modifications to align with the Administration's climate change and environmental justice policies in Executive Order 14148 of January 20, 2025. These requirements are for onshore non-transportation-related facilities that could reasonably be expected to cause substantial harm to the environment from a CWA hazardous substance worst case discharge to navigable waters, adjoining shorelines, or the exclusive economic zone. This delay action is necessary to allow the Agency to consider implementation and compliance assistance tools that regulated parties may be able to take advantage of when complying with the new requirements. EPA notes that it cannot quantify the number, nature, and magnitude of covered discharges that may occur during the proposed rule delay period. Comments must be received on or before 6 April 2026.
