Politics over people in GHG deregulation

EPA finalized the rescission of its 2009 greenhouse gas (GHG) endangerment finding on February 18, 2026. This final rule also removes GHG emission standards for motor vehicles and engines. Believing that regulating GHG emissions is futile for combating climate change, the agency makes tenuous legal arguments and cites reports that violate federal law. Expect lawsuits. READ MORE

BYD and blade batteries

As EVs continue to evolve, BYD (Build your Dreams) automotive brand is pushing its technology related to electronics, autos, renewable energy and rail transit. BYD incorporates the blade battery because of its exceptional safety and long lifespan. Blade batteries are a form of lithium iron phosphate (LFP) known for their flat, elongated shape that saves space in its line of EV models. Learn more about BYD EVs here

Coal pollution up with MATS reversal

First proposed in 2025, EPA has repealed its May 2024 revisions to the mercury and air toxics standards (MATS) for coal- and oil-fired electric utility steam generating units. The rescission creates less stringent emission standards for mercury and filterable particulate matter and increases the health costs borne by the American populace. These changes are the next in a long line of recent deregulatory efforts spearheaded by EPA. READ MORE

EPA to deny regulating radioactive phosphogypsum

Radioactive phosphogypsum is considered a “large volume, low hazard” waste stream and is not a RCRA hazardous waste. In 2021, the Center for Biological Diversity sought to change that determination, hoping to pull this mineral processing by-product under the RCRA Subtitle C umbrella, but EPA recently proposed to deny their petition. If finalized, EPA’s determination would allow billions of tons of phosphogypsum to remain in large above-ground piles while only the pile’s outer crusted layer blocks radon gas emissions. READ MORE

Take a vacation

Your brain will thank you. While our work life beckons and it’s essential to be able to pay our bills, support our identity, bring meaning to our work, and maintain our lifestyle, there is more to taking a vacation than we think and the consequence of skipping time off is real.

Coal ash in playgrounds? Maybe

EPA recently proposed significant amendments to weaken coal combustion residual (CCR) regulations for power plants. [91 FR 18968] The proposed rule would allow certain legacy CCR surface impoundments to avoid permitting, rescind all CCR management unit requirements, expand exemptions to allow beneficial use of coal ash, eliminate closure standards, and create a host of other provisions not protective of human health and the environment. The proposal stems from an industry white paper calling for what amounts to the dismantling of the Part 257, Subpart D regulations and their environmental protections. Comments on the proposal may be submitted through June 12, 2026 via Docket ID No. EPA-HQ-OLEM-2020-0107.

NSPS and EG updates for waste combustors

New rules for new and existing large municipal waste combustors took effect on May 11, 2026. EPA’s revisions to the new source performance standards (NSPS) and emission guidelines (EG) for these units result in tighter emission limits, the elimination of the startup, shutdown, and malfunction exemption, and the removal of Title V permitting for certain air curtain incinerators. The rule is a result of a voluntary remand and is the first change to these rules in 20 years. READ MORE

Big changes to PEPO NESHAP

Polyether polyols (PEPO) are used in the production of lubricants, adhesives, sealants, cosmetics, pharmaceuticals, soaps, and more. The production of these chemicals releases numerous hazardous air pollutants and is regulated under the CAA’s NESHAP program. Recently, EPA finalized significant changes to the PEPO NESHAP, strengthening MACT standards and broadening the applicability of this source category. READ MORE
