1. (1) Purpose. The purpose of the no further action sites list is to identify:

   1. (a) All sites where ecology or PLIA has determined no further remedial action is necessary under state cleanup law to meet the criteria in WAC 173-340-330(5); and
   2. (b) For each listed site, whether institutional controls or periodic reviews remain necessary at the site.

2. (2) Adding a site to the list. Ecology will add a site to the no further action sites list if, and only if:

   1. (a) After completing an initial investigation, ecology or PLIA determines that no further remedial action is necessary under state cleanup law to meet the criteria in WAC 173-340-330(5); or
   2. (b) Ecology removes the site from the contaminated sites list based on the criteria in WAC 173-340-330(5).

3. (3) Tracking institutional controls and periodic reviews. For each site on the no further action sites list, ecology will identify on the list whether the site requires:

   1. (a) Institutional controls under WAC 173-340-440; or
   2. (b) Periodic reviews under WAC 173-340-420.
4. (4) Removing a site from the list. If ecology relists a site on the contaminated sites list under WAC 173-340-330(8), ecology will remove the site from the no further action sites list.

5. (5) Notification.

   1. (a) Ecology will make the no further action sites list publicly available on ecology's website.
   2. (b) If requested, ecology will notify a person electronically under WAC 173-340-600(6) upon adding or removing a site on the no further action sites list.
