Finding-Purpose-Effective date-1994 c 281: See notes following RCW 70A.105.020.
Intent-1993 c 321: "The legislature finds that most additives do not have a positive effect on the operation of on-site systems and can contaminate groundwater aquifers, render septic drainfields dysfunctional, and result in costly repairs to homeowners. It is therefore the intent of the legislature to ban the use, sale, and distribution of additives within the state unless an additive has been specifically approved by the department of health."
