Proprietary Treatment Products Emergency Rule

Emergency Rule Adoption - Chapter 246-272A-0110

The Washington State Department of Health (department), working with the State Board of Health, adopted a second emergency rule to allow on-site sewage systems (OSS) proprietary treatment products to be operated and maintained with the best components available during an ongoing supply chain shortage. The first emergency rule was effective through October 12, 2022.

This rule is effective October 13, 2022.

Emergency rule effective through February 9, 2023.

This emergency rule:

  • Allows manufacturers to propose changes to the department for retrofitting components of their proprietary products under prescribed circumstances.
  • Ensures substituted proprietary products are not negatively impacting the treatment, operation, or maintenance.
  • Ensures public health and environmental protections are maintained while limiting delays on home sales.

We are investigating a long-term solution to consider as part of the permanent rulemaking while this emergency rule is in effect.

Information for Manufacturers

Manufacturers of products impacted by a supply chain shortage can submit to the department a written plan that ensures proprietary systems are not negatively impacted in their treatment, operation, or maintenance.

Once the department receives the written plan, we will be in contact if there are any questions or concerns. Manufacturers will receive written notification from the department when we approve the plan.
