Model remedies.
(1) Purpose. The purpose of model remedies is to streamline and accelerate the selection of a cleanup action for routine types of cleanup projects at sites with common features and lower risk to human health and the environment.
(2) Development of model remedies. Ecology may establish model remedies for common categories of sites, types of hazardous substances, types of media, and geographic areas.
When establishing a model remedy, ecology will:
(a) Identify the applicability of the model remedy for use at a site, the site characterization required under WAC
173-340-350 to select the model remedy, and the compliance monitoring required under WAC
173-340-410 to implement the model remedy;
(b) Describe how the model remedy meets the cleanup standards established under Part 7 of this chapter and the requirements for cleanup actions in WAC
173-340-360; and
(c) Provide the public with notice and an opportunity to comment on the proposed model remedy and the conditions under which it may be used at a site. The public comment period must be at least 30 days.
(3) Soliciting proposals. When developing model remedies, ecology will solicit and consider proposals from qualified persons. The proposals must, in addition to describing the model remedy, provide the information required under subsection (2)(a) and (b) of this section.
(4)
Selection. A model remedy may be selected as a cleanup action, or as a component of a cleanup action, at a site without conducting a feasibility study under WAC
173-340-351, provided that:
(a) The site meets the conditions for using the model remedy identified by ecology under subsection (2)(a) of this section. To make this demonstration, sufficient information must be collected and documented during the remedial investigation (see WAC
173-340-350 (6)(j)(ii) and (5)(f)(ii) and (g)(vii)); and
(b) For ecology-conducted and ecology-supervised remedial actions, ecology provides or requires public notice of the proposed use of the model remedy in the draft cleanup action plan under WAC
173-340-380.
