Regulatory Update: New Senate Resolution Would Overturn the Federal Approval Behind California's 2028 Pressure Washer Rules.
By • September 1, 2026

NEW CONGRESSIONAL ACTION ON CALIFORNIA'S 2028 PRESSURE WASHER RULES
On August 5, Senator Cynthia Lummis of Wyoming, joined by eight other senators, introduced S.J. Res. 205—a resolution under the Congressional Review Act that would overturn the EPA authorization behind California's updated SORE regulations. If the resolution passes both chambers of Congress and is signed by the President, the federal approval supporting these rules would have no force or effect.
The Congressional Review Act gives the resolution a faster path than most legislation: it cannot be filibustered in the Senate, and Congress used this same process in 2025 to overturn other California emissions approvals. The resolution is currently before the Senate Environment and Public Works Commitee, and a floor vote could come as early as this fall after the Senate
returns on September 14.
Prior to this congressional action, PWNA met directly with CARB in April during its SORE Technology Review to explain the performance, hot-water, portability, and continuous-runtime requirements of professional work.
PWNA has now formally shared the industry's technical and economic concerns with the Senate commitee considering S.J. Res. 205 and continues working with regulators, policymakers, allied associations, and manufacturers.
Members are encouraged to weigh in now. Senators are home in their states until September 14, when offices are especially attentive to local business owners. Use the sample email, two-minute phone script, and committee roster in the Call to Action Kit included in this update.
PWNA Call to Action Kit
Contact your own senators first. If a senator from your state serves on the Senate Environment and Public Works Committee, prioritize that office as well. A brief call or email can make a difference, and the Call to Action Kit below makes it easy to act in about 10 minutes:
- Find your two senators at senate.gov/senators and call or email both, asking them to support S.J. Res. 205.
- A short, personal message is most effective: who you are, where your business is, and that commercial-grade zero-emission equipment doesn't yet exist for the work you do.
- Use the sample email and two-minute phone script in the Call to Action Kit below.
Personalize either one with your business, location, and real-world equipment needs.
Subject: Please Support S.J. Res. 205
Dear Senator [Last Name],
My name is [Name], and I own/work for [Business] in [City, State]. I am a constituent and a member of the Power Washers of North America (PWNA). I am writing to ask you to support S.J. Res. 205.
Professional exterior cleaning businesses rely on commercial equipment that must deliver high flow and pressure, often with hot water, portability, and continuous runtime at job sites without electrical service. PWNA is not aware of commercially available zero-emission equipment that can match all of these requirements for many professional applications.
PWNA supports cleaner technology whenever it can meet the demands of professional work. However, the 2028 standards for newly manufactured large pressure washer engines should reflect commercially available technology and realistic compliance for small businesses.
Although existing CARB-compliant equipment may continue to be used and repaired, future equipment availability remains critical to our businesses and customers.
Please support S.J. Res. 205 and let me know your position on the resolution.
Thank you for considering the perspective of professional contractors and small business owners in [State].
Sincerely,
[Name]
[Business]
[City, State, ZIP]

TWO- MINUTE PHONE SCRIPT
Use this as written or adapt it to your own experience. Ask the staff member to record your position and request a response from the senator.
Hello, my name is [Name], and I am a constituent from [City, State, ZIP]. I own/work for [Business], a professional exterior cleaning company. I am calling to ask Senator [Last Name] to support S.J. Res. 205.
Our industry relies on commercial pressure washing equipment that must provide high flow and pressure, often with hot water, portability, and long continuous runtime at job sites without electrical service. PWNA is not aware of commercially available zero-emission equipment that can meet all of these requirements for many professional applications.
We support cleaner technology when it can do the job, but the 2028 standards for new large pressure washer engines should be based on available technology and realistic small-business compliance.
Please record my request that Senator [Last Name] support S.J. Res. 205. I would also appreciate a response explaining the senator's position. My phone number is [Phone], and my email is [Email].
Thank you for your time.
