California SB-317 Explained


Here at WTF we want to ensure you and your RV remain awesome . . . and on the good side of California’s legal system. But understand, we’re not lawyers and are only providing you this information for educational purposes. If you really need legal advice when it comes to dumping your tank or any other matter, please contact a lawyer.

Now that we have the disclaimer out of the way, let’s jump into what California’s SB-317 ruling is and how it can impact you and your RV travels.

SB-317 Summarized

  • Chemicals bad
  • Bacteria and enzymes good
  • Don’t screw with the groundwater

What does SB317 Mean for Your RV Travels?

If you’re a smart RVer, and we know you are because you’re spending some time with us, then you already are using an outstanding tank treatment that utilizes beneficial bacteria and enzymes. Sounds a lot like Waste Tank Formula.

The bottom line is that we want you to have a healthy RV tank and so does the state of California. California is just trying to keep their water table as free of chemicals as possible, and that is the basis of this ruling.

If you have any question as to what products are California SB317 compliant, just go on Amazon and select a shipping address in California and see if the product will ship. If it will, your good to go . . . if not, it likely contains one or more of the banned chemicals.

California’s SB317 Banned Chemicals

According to California’s SB-317 the following chemicals are considered a no-no and not allowed for use, sale, or purchase in the Golden State:











Ethylene Glycol




California’s SB-317 in Their Words

“The State of California prohibits the use of products in RV holding tanks, including deodorizers, that contain bronopol, dowicil, formalin, formaldehyde, glutaraldehyde, paraformaldehyde, para-dichlorobenzene, benzene, toluene, xylene, ethylene glycol, 1,1,1-trichloroethane, trichloroethylene, or perchloroethylene. These chemicals can inhibit biological activity in onsite wastewater treatment systems and threaten groundwater and drinking water wells, and are strictly forbidden. Please use bacteria- or enzyme-based products.

Parting Thoughts

We created WTF as an effective and environmentally friendly treatment for all your waste tanks. We’re not big fans of chemicals and feel they have no place in your RV or boat’s holding tanks. This philosophy just happens to align with the SB317 ruling.

So get out there in your rig, drop a tab in the toilet, and feel good about yourself!
