(2) The notice must be posted in a visible, publicly accessible location on the facility, to remain in place until all remedial actions except confirmational monitoring are complete.

An exemption from the notification requirements of this section does not exempt the owner or operator of a facility from any other notification or reporting requirements, or imply a release from liability under this chapter.
