California Withdraws EPA Waiver Request for Zero-Emission Advanced Clean Fleet Regulations

California’s Air Resources Board (CARB) on Jan. 13 sent a letter to withdraw its request to the Environmental Protection Agency pursuant to Sections 209(b) of the Clean Air Act (CAA) for a federal waiver that would require commercial truckers to switch to using zero-emissions vehicles in accordance with the CARB’s Advanced Clean Fleets regulation (ACF).

Had it been granted a waiver, CARB would have been allowed to put into effect the drayage and “high priority fleets” provisions of the ACF. CARB first requested this wavier …

Surf’s up: Wave energy no longer confined to sports venues

Can wave-energy be a green-power solution for coastal communities? That question may be at least partially answered in Newport, Oregon, a small seaside town cooperating with the U.S. Department of Energy in an attempt to convert wave power into electricity. Newport expects the project to provide enough energy to power thousands of its homes and businesses.

The process uses buoy-type converters located miles offshore. These converters transfer energy to underwater connectors into which they are plugged. From the connectors, cables buried underneath the seafloor carry …

A salted battery: will sodium-ion technology change the electric-power game?

We have relied upon lithium-ion batteries to power electric vehicles and mobile phones, among other things, almost since the inception of their respective industries. But the mining and processing necessary to manufacture these batteries provides one of their major drawbacks—not only does their production pose environmental and human costs, but their improper disposal can inject toxins into the environment.

Sodium, which is both cheaper and more environmentally friendly than lithium, recently emerged as a promising alternative. Sodium-ion batteries also last much longer than their lithium-based …

Law Gives California’s Energy Commission Ability to Nudge Oil Refiners to Make Better Inventory Decisions

California Gov. Gavin Newsom on October 14 signed into law Assembly Bill X2-1, significantly increasing the authority of the California Energy Commission (CEC) to create requirements for the state’s oil refiners to preserve minimum inventories of state-compliant refined transportation fuels.

Authored by assemblymembers Gregg Hart and Cecilia Aguiar-Curry in conjunction with Sen. Nancy Skinner, the law take effect in January 2025 and expands the powers of the recently created Division of Petroleum Market Oversite (DPMO) within the CEC.

DPMO was created last year as …

California Retains Jurisdiction Over Fossil Fuel Companies Named in Climate Change Lawsuits

The ELM blog has covered several lawsuits filed over the past several years against major fossil fuel companies by plaintiffs seeking damages due to climate change caused by greenhouse gas emissions. The claims in these lawsuits have been based on not only common law principles such as public nuisance, but also state laws, including California’s consumer protection laws.

While these lawsuits have had slight differences, one common theme running through them is the defense raised by the oil companies that state courts, like California’s, lack …

Betting on a power-industry glow-up, Big Tech goes nuclear to stop A.I.-driven energy meltdown

Artificial Intelligence is Big Tech’s newest toy. However, AI also requires massive amounts of energy to operate, which puts the industry’s climate commitments at risk. The sprawling data centers that Microsoft and other digital giants need are beginning to strain the nation’s existing power supplies. Meta Platforms recently reported last year’s emissions were roughly 70-percent above 2019 levels. Microsoft’s emissions jumped 40-percent in the three-year period through June 2023, while Google’s surged nearly 50-percent in the four years through December.

These energy needs have rapidly changed …

California May Put Its Historic Climate Disclosure Laws on Hold

In an update to the Environmental Law Monitor’s continuing coverage of California’s historic climate disclosure laws, California State Sen. Scott Weiner put forth on August 13 proposals to Senate Bill 219 that would delay the effective date of the Golden State’s 2023 emissions and climate-related financial risk corporate disclosure laws.

As our readers may remember, signed into law back in November 2023, the legislation at issue were SB 253 and SB 261, which created landmark greenhouse gas emission and climate-related financial risk reporting requirements …

Appellate Court Vacates FERC’s Approval of $950M Natural Gas Pipeline Project

Late last month, the U.S. Court of Appeals for the District of Columbia Circuit, in New Jersey Conversation Foundation, et al. v. FERC, unanimously vacated the Federal Energy Regulatory Commission’s (FERC) approval of the Transcontinental (Transco) Gas Pipe Line Company Regional Energy Access Expansion Project.

The roughly $950 million gas pipeline project involves the construction and operation of over 36 miles of new natural gas pipeline facilities built by a Williams Co. subsidiary. In addition to the pipeline, the project called for the …

EPA Seeks Input from Small Businesses on Proposed Regulations for Drinking Water

Opportunity knocks for water treatment entities to provide their input on new regulations about to be rolled out by EPA that could either boost or harm their businesses. The Regulatory Flexibility Act requires EPA to establish a panel, including small businesses that may be economically impacted before any revisions to regulations become effective. But beware, the deadline only provides one week to apply.

The Safe Drinking Water Act (SDWA) requires the U.S. Environmental Protection Agency to conduct a review every six years covering the existing …

EPA not Afraid of Changin’, Wants Landfills to Bring it (Methane Emission) Down

The Environmental Protection Agency intends to issue a rule updating its Clean Air Act emission standards for new and existing municipal solid waste (MSW) landfills to cut methane and other harmful landfill gas emissions. 

The rule follows another Clean Air Act-related proposal the EPA issued in January, designed to reduce emissions of nine pollutants, including smog- and soot-forming sulfur dioxide and nitrogen oxides by approximately 14,000 tons per year at MSW incinerators, as found here.

The EPA expects landfill operators to achieve these standards …
