time of Transfer / sale inspection

Thurston County's sewage system regulations (Article IV) were updated on May 18, 2010 to meet the minimum requirements of state law WAC 246-272A-0015.  A key part of these amendments is a requirement for the evaluation of On-Site Sewage System (OSS) when the property they serve is sold or transferred.  The requirement was put in place to help inventory sewage systems and identify and assure the timely repair of Failing Sewage Systems.
