Today: The Environmental Protection Agency is looking to end Biden-era rules on PFAS; a mega U.S. energy deal faces up to the reality of convincing state regulators; and electric-vehicle drivers in America face a $130 charge.

Welcome back: The Environmental Protection Agency unveiled proposals that would end Biden-era limits for certain so-called forever chemicals in drinking water and allow utilities to seek a delay in meeting a deadline for reducing other such chemicals.

In discussing the proposals Monday, EPA leader Lee Zeldin and Health and Human Services Secretary Robert F. Kennedy Jr. sought to assuage concerns about the Trump administration’s stance on forever chemicals, or PFAS, saying the agency may issue its own rules to replace the one it intends to cut, WSJ Pro Sustainable Business’s Clara Hudson reports.

The first proposed change would undo a Biden-era forever chemicals requirement that the Trump EPA said doesn’t hold up because the past administration didn’t follow procedure when implementing it. Those rules set limits for a handful of PFAS, including those known as GenX.

NextEra Energy and Dominion Energy have agreed to combine in a blockbuster utilities deal. Now comes the hard part: a regulatory marathon.

The companies must convince a web of state and federal regulators that combining two of the U.S.’s largest utilities will benefit customers and avoid increasing electricity bills at a time of heightened scrutiny on consumer costs and grid reliability, the Journal’s Jennifer Hiller reports.

The $67 billion deal would create an East Coast energy behemoth with 10 million customer accounts in Florida, the Carolinas and Virginia. It would be the largest U.S. electricity producer—specifically the biggest provider of natural gas-fired power and No. 2 in nuclear, the companies said.

The tie-up will test the Trump administration’s willingness to consider mergers that reshape industries. It needs approval from utility commissions in Virginia, North Carolina and South Carolina, which are increasingly focused on making sure data centers shoulder the cost of grid upgrades and new power plants. It will also require the approval of the Federal Energy Regulatory Commission and the Nuclear Regulatory Commission.

When drivers pump gasoline, a small tax on each gallon contributes $30 billion a year to maintain the interstate highway system. But what about cars that don’t use gasoline at all?

If a proposed House of Representatives bill becomes law, electric-vehicle owners would face an annual, nationwide registration fee to chip in for road repairs—but EV advocates say those drivers would be asked to do too much, the WSJ's Sean McLain reports.

The bipartisan bill, sponsored by Reps. Sam Graves (R., Mo.) and Rick Larsen (D., Wa.), proposes charging a registration fee every year to EV owners. The amount would start at $130, rising every two years until it hits $150.

Drivers of plug-in hybrid cars, which still use gasoline but are more fuel-efficient than gasoline cars, aren’t off the hook, either; those drivers would pay $35 every year, with the amount gradually rising to $50.
