AN ACT Relating to on-site wastewater treatment system inspections;
Summary
SB6291 amends Washington law governing inspections and reviews of on-site wastewater treatment systems, commonly known as septic systems. The bill directs local boards of health to ensure that individuals who inspect or review these systems are qualified in the technology and application of on-site sewage treatment principles. It states that a certificate of competency from the state board of registration for professional engineers and land surveyors is sufficient proof that a person is competent in the engineering aspects of on-site wastewater treatment system technology.
The bill also creates a temporary pathway for noncertified individuals to perform design reviews and inspections under supervision. A local board of health may allow a noncertified person to do this work for up to two years after hire, so long as a certified individual reviews or supervises the work during that period. The supervised practice period may continue for up to four years after the date of hire, providing a longer transition period for training and workforce development.
Impact
SB6291 changes the standards local health jurisdictions must use when determining who may inspect or review on-site wastewater treatment systems under RCW 18.88A. It affects local boards of health, inspectors, reviewers, and employers in the wastewater and environmental health fields by clarifying qualification requirements and allowing limited supervised practice for noncertified staff. The bill is intended to support staffing and training while maintaining technical competency in septic system oversight.
Sentiment
The bill appears to have been broadly supported and noncontroversial. It passed the Senate and House with unanimous or near-unanimous votes, including committee approval and final passage in both chambers without any recorded opposition. The voting history suggests general agreement that the measure was a practical workforce and regulatory update.
Contention
There is little evidence of substantive contention in the available record. The only likely policy tension is between maintaining strong qualification standards for septic system inspections and allowing noncertified individuals to work under supervision for a limited period. Supporters likely viewed the supervised-practice provision as a necessary workforce flexibility measure, while any concern would center on ensuring public health protections are not weakened.
