Water Wars Over Appliance Efficiency
For many people, having a dishwasher or clothes-washing machine is a necessity. For others, it’s a luxury. But what’s not up for debate is that historically, those machines drink a lot of water.
Standards for water efficiency in dishwashers and clothes washing machines have undergone significant changes over time—but not on their own. The U.S. Department of Energy (DOE) had much to do with it, establishing standards for efficiency that manufacturers of residential clothes washers and dishwashers must comply with.
But currently, a legal battle challenges the DOE’s authority to impose water-efficiency standards on these machines.
DOE Standards
This past June, two individuals in Texas and New Orleans filed a lawsuit against the United States Department of Energy (DOE) in the Northern District of Texas, Amarillo Division. They claimed that the DOE exceeded its statutory authority under the Energy Policy and Conservation Act of 1975 (EPCA).
The plaintiffs specifically challenged two Direct Final Rules (DFRs) issued by the DOE that amended water-efficiency standards for residential clothes washers and dishwashers. Earlier this summer, the DOE had published these amended standards, effective July 15, 2024, with compliance required by March 1, 2028. These standards aim to improve energy and water efficiency.
This decision was part of DOE's broader efforts to enhance appliance efficiency, reduce environmental impact, and lower consumer costs. According to the DOE, the standards for dishwashers and clothes washers were developed through stakeholder engagement and public comment, ensuring they are feasible and beneficial for both manufacturers and consumers—but clearly, everyone wasn’t happy.
Can the DOE Regulate Appliances?
We’re not exactly sure what bones the plaintiffs had to pick with the DOE’s new standards (public filings don’t include those details). Still, it doesn’t matter for legal purposes because the way they framed the dispute wasn’t challenging the appropriateness of the standards themselves. Instead, it was challenging the DOE’s action in making any standards at all.
The plaintiffs argued that the DOE did not have the legal authority to regulate water efficiency for these appliances. Their argument was based on the legislative history and statutory language of the EPCA.
They contended that the EPCA, as originally enacted and subsequently amended, only granted the DOE authority to regulate water efficiency for certain plumbing products (think showerheads, faucets, water closets, and urinals). The plaintiffs pointed out that the EPCA's "energy conservation standard" definition included water use only for these specified products, which do not use energy.
The plaintiffs further argued that Congress had explicitly considered and rejected expanding the DOE's authority to regulate water efficiency for energy-using appliances like clothes washers and dishwashers. They cited legislative history, including congressional hearings and proposed amendments, to demonstrate that Congress had decided not to grant the DOE such authority. For instance, during discussions on the Energy Independence and Security Act of 2007, they pointed out that there were proposals to amend the EPCA to include water efficiency standards for clothes washers and dishwashers, but these proposals were ultimately not enacted.
The plaintiffs maintained that the DOE's issuance of the DFRs imposing water efficiency standards on clothes washers and dishwashers was beyond its legal power. They reasoned that the DOE's actions were inconsistent with the statutory framework established by Congress. In their view, the regulations unlawfully restricted their choice of appliances by imposing standards that were not authorized by law. They asked the federal court to prevent the DOE from enforcing these standards.
DOE Fights Back
The DOE wasn’t going to take that sitting down. First, they argued that the case should be dismissed, since the plaintiffs didn’t do things by the rules by bringing their dispute to district court. The EPCA specifically prescribes the procedures for judicial review of its rules, directing that any person adversely affected by a rule may file a petition for review with the United States court of appeals for the circuit where the person resides or has their principal place of business. The DOE contended that this statutory language indicates that jurisdiction over such challenges lies exclusively with the appellate courts, not district courts.
The DOE further argued that the kind of agency action challenged by the plaintiffs—rulemaking proceedings—does not typically require additional fact-finding by a district court, making appellate review more appropriate. It emphasized that the EPCA's jurisdictional grants to district courts are limited to specific issues, none of which were at issue in this case.
Court Dismisses Suit
United States District Judge Matthew J. Kacsmaryk agreed, granted the DOE's motion to dismiss. The court found that the statutory language and legislative intent of the EPCA clearly favor giving exclusive jurisdiction to the appellate courts. The statute specifies that any person adversely affected by a rule may file a petition for judicial review with the United States court of appeals for the circuit in which they reside or have their principal place of business. The court interpreted "may" in this context as "must," thereby indicating exclusive appellate jurisdiction. The court referenced similar cases where statutory language was interpreted to favor appellate review when there was a specific statutory grant of jurisdiction to the courts of appeals.
The court also agreed with the DOE that the EPCA confers exclusive jurisdiction to appellate courts for such challenges. The court noted that the statutory structure of the EPCA supports this interpretation, as it provides a general grant of jurisdiction to the appellate courts and only carves out specific issues for district court review, none of which were applicable in this case.
The court reasoned that district courts are not the appropriate forum for reviewing the type of agency action challenged by the Plaintiffs. Rulemaking proceedings, such as those involved in the issuance of DFRs, typically do not require additional fact-finding by a district court, which is more suited for issues like determining compliance with state or local government requirements under the EPCA.
What Next?
The court's decision effectively ended the district court proceedings, directing the plaintiffs to seek any further legal recourse in the appropriate appellate court. All this just means that if those opposing DOE standards want to bring litigation over it, they can still do so—they just have to refile in a higher court. This probably means that the battle for energy efficiency—and the DOE’s regulatory authority—is far from over.
