Proprietary Treatment Products Emergency Rule

Proprietary Treatment Products Emergency Rule - Withdrawn

On April 1, 2024, the Department of Health (Department) filed a withdrawal memo to rescind the CR-103E for the Sixth Emergency rule for proprietary treatment products and the use of substitution products under WAC 246-272A-0110, which was filed February 2, 2024, and published in WSR 24-04-071.

The Department rescinded the CR-103E because the State Board of Health filed a permanent rule that addresses the underlying need for the emergency rule, making the emergency rule redundant. Permanent rules were filed on March 1, 2024, under WSR 24-06-046.

Visit the DOH On-site Sewage System Rule Revision website for more information about the permanent rule update.
