Analyzed Economic Effects
8 provisions identified: 0 benefits, 8 costs, 0 mixed.
Secondary Containment for New/Replacement Tanks
Nevada requires a secondary containment system for underground tanks installed on or after July 1, 2008, and when tank piping or tanks are replaced (see NAC 459.9945 and 459.9946). Those requirements are part of the Nevada rules incorporated into the CFR effective December 21, 2026.
Financial Responsibility Requirement
Owners and operators must demonstrate financial responsibility for underground storage tanks under Nevada law (see NAC 459.995); this requirement is included in the Nevada UST Program incorporated into the CFR effective December 21, 2026.
Release Response, Assessment, and Corrective Action
Nevada's rules require reporting releases, site protection, inspections, site assessments before tank closure, and corrective action for contaminated soil or groundwater (see NAC 459.996, 459.9972, 459.9988). These obligations are part of the Nevada program incorporated into the CFR effective December 21, 2026.
1‑Day Release Reporting Requirement
If you own or operate an underground storage tank (UST) in Nevada, you must notify the Division within 1 working day after a confirmed release from a UST (see NAC 445A.347). These provisions are incorporated into the federal CFR as part of the Nevada UST Program codified effective December 21, 2026.
Operator Training and Certification
Nevada requires designation of Class A, B, and C UST operators and completion of operator training and examinations with records of completion maintained (see NAC 459.99395 and 459.99396). These operator requirements are incorporated into the federal CFR as of December 21, 2026.
Tank Tightness Testing Requirement
Nevada requires testing of underground storage tanks for tightness (see NAC 459.994); that testing requirement is part of the Nevada regulations incorporated into the CFR effective December 21, 2026.
Under‑Dispenser Container Requirement (with Waivers)
Nevada requires under‑dispenser containment for certain fuel dispenser systems and allows the Nevada Division of Environmental Protection to waive the requirement in certain circumstances (see NAC 459.9948). This requirement and waiver authority are incorporated into the CFR effective December 21, 2026.
Federal Enforcement Authority Retained
The EPA retains authority to undertake corrective actions, inspections, enforcement actions, and to issue orders in Nevada under RCRA sections cited in the rule; if EPA acts it will use Federal sanctions and inspection authorities rather than only State procedures. This codification into 40 CFR part 282 becomes effective December 21, 2026.

2026-20849, Clean Water Act Hazardous Substance Facility Response Plans: Compliance Date Delay and Changes To Reflect Administration Policy
The EPA is giving facilities more time to meet new Clean Water Act rules for handling hazardous spills, pushing back the deadline to help them get ready. They’re also removing mentions of climate change and environmental justice to match new government policies. This delay helps facilities plan better without rushing and lets the EPA rethink the rules if needed.
2026-19071, Partial Repeal of the Carbon Pollution Standards for Fossil Fuel-Fired Electric Generating Units
The EPA is rolling back most of the 2024 rules that limited carbon pollution from fossil fuel power plants. This change affects coal and gas plants by easing some strict limits on emissions and carbon capture technology. The new rules kick in on November 16, 2026, potentially saving money for power plants but raising questions about pollution control.
2026-19072, Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under Clean Air Act Section 111
The EPA is proposing to cancel all greenhouse gas rules for fossil fuel power plants, saying the law doesn’t let them regulate these emissions for climate reasons. This change affects power plants across the U.S. and could impact future pollution limits and costs. Comments on this proposal are open until November 2, 2026, so now’s the time to speak up!
2026-18317, Updated Definition of “Waters of the United States”
The purpose of this supplemental notice of proposed rulemaking is for the U.S. Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") to supplement and seek additional comment on certain aspects of an earlier proposal, published on November 20, 2025, to revise the regulations defining the scope of waters federally covered under the Clean Water Act in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. As stated in the agencies' November 20, 2025 Notice of Proposed Rulemaking (NPRM), the agencies intend for this rulemaking to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." After consideration of the public comments received on the NPRM, the agencies are issuing this notice to supplement the NPRM with additional regulatory options on certain aspects of the proposed rule.
2026-14112, Amendments and Nonconformance Penalties for Model Year 2027 and Later Heavy-Duty Highway Engines and Amendments to Inducement Provisions for SCR-Equipped Diesel Engines
Starting with model year 2027, the EPA is updating rules for big truck engines to make sure they last longer and pollute less. They’re also letting engine makers pay penalties if their engines don’t meet standards, and tightening rules for special pollution-control systems on diesel engines. These changes affect truck and engine makers and kick in soon, with public feedback due by August 29, 2026.
2026-13667, Minor New Source Review Program Air Permitting Public Participation Requirements for State Implementation Plans
The EPA wants to give states more freedom to decide how much public input is needed when approving small air pollution sources or changes. This means local air agencies can tailor public participation to fit their community’s needs while still protecting air quality. If you’re involved in air permits, watch for comment deadlines and possible virtual hearings this summer!

Starting January 20, 2027, anyone sending or receiving international mail shipments valued at $2,500 or less will need to follow a new, official entry process because the old 'de minimis' duty-free exemption is paused indefinitely. This change affects importers and postal customers who must now comply with updated customs rules, giving them more time to get ready. It could mean more paperwork but helps keep trade fair and secure.
