The bill amends RCW 70A.105.110 to enhance the qualifications required for individuals conducting inspections of on-site wastewater treatment systems. It specifies that these individuals must be qualified in the technology and application of on-site sewage treatment principles, with a certificate of competency from the state board of registration for professional engineers and land surveyors serving as proof of competency in engineering aspects.

Additionally, the bill allows local boards of health to permit noncertified individuals to review designs and conduct inspections of these systems under the supervision of a certified individual. This supervised practice can now extend for a maximum of four years after the date of hire, an increase from the previous limit of two years. The bill clarifies the definition of on-site wastewater treatment systems by referencing RCW 18.210.010 in the context of these regulations.
