OSS Management Plan Committee - Vision Statement
“Our goal is to protect public health in Thurston County by assuring that on-site sewage systems are properly designed, permitted, built, operated, and maintained or abandoned. As we update the OSS Management Plan, we will strive to accomplish this goal by evaluating the effectiveness of current programs and study findings, complying with requirements of state regulations, and meeting the needs of the citizens of Thurston County.”
