Bill > SB6291

This bill amends existing law concerning on-site wastewater treatment system inspections, which are systems used to treat sewage on a property when a public sewer system is not available. The key change is that non-certified individuals can now conduct inspections and review designs of these systems for up to four years after being hired, provided they are supervised by a certified individual, extending the previous two-year limit and clarifying the supervision requirement. The bill also explicitly defines "on-site wastewater treatment systems" by referencing another section of law (RCW 18.210.010) to ensure clarity on what types of systems are covered by these inspection rules.
