(1) Purpose. Public participation is an integral part of ecology's responsibilities under chapter 70A.305 RCW, the Model Toxics Control Act. Ecology's goal is to provide the public with timely information and meaningful opportunities for participation that are commensurate with each site. Ecology will meet this goal through a public participation program that includes:

(a) Site-specific information on ecology's website;

(b) A Contaminated Site Register and, if requested, site-specific electronic alerts of changes to site information; and

(c) For ecology-conducted and ecology-supervised remedial actions, early planning and development of site-specific public participation plans, public notice of proposed actions, and public meetings or hearings.

(2) Public notice. Whenever public notice of a proposed action is required under this chapter, ecology will provide or require at least the following notice and opportunity to comment.

(a) Notification methods.

(i) Website. Ecology will make the proposed action publicly available on ecology's website under subsection (5) of this section;

(ii) Electronic alert. If requested, ecology will alert a person electronically of the proposed action's availability under subsection (6) of this section;

(iii) Contaminated Site Register. Ecology will provide notice of the proposed action's availability in the Contaminated Site Register under subsection (7) of this section.

(iv) Persons requesting notice. Written notice must be sent to persons who have made a timely request of ecology. A request for notice is timely if received before or during the public comment period for the current phase of remedial action at the site. However, the receipt of a request for notice does not require ecology to extend the comment period associated with the notice. Ecology may use an electronic alert under subsection (6) of this section to satisfy this requirement.

(v) Persons residing within potentially affected vicinity. Written notice must be sent to persons residing within the potentially affected vicinity of the proposed action. The potentially affected vicinity includes all property within and contiguous to the site and any other area that ecology determines to be directly affected by the proposed action.

(vi) Appropriate news media. Written notice of the proposed action must be sent to any news media that ecology determines to be appropriate. Ecology may consider how a news medium compares with the newspaper of largest circulation in terms of: Audience reached; timeliness; adequacy in conveying the particular information in the notice; cost; or other relevant factors.

(vii) Newspaper publication. If required under chapter 70A.305 RCW or by ecology, written notice of the proposed action must be published in the newspaper of largest circulation in the city or county of the proposed action, by one or more of the following methods: Display ad; legal notice; or any other appropriate format, as determined by ecology.

(b) Comment opportunity.

(i) Comment periods. A public notice must indicate the public comment period on the proposed action. Unless otherwise specified in this chapter, the public comment period must be at least 30 days. Ecology may extend the public comment period, as appropriate.

(ii) Public meetings. During any comment period announced by a public notice issued under this chapter, if 10 or more persons request a public meeting on the subject of the public notice, ecology will hold a public meeting for the purpose of receiving comments.

(c) Consolidating notice and comment opportunities. Whenever reasonable, ecology will consolidate public notice required under this chapter with notice and comment opportunities required under other laws and regulations.

(d) Site-specific risk assessment. For public notices describing cleanup plans that use site-specific risk assessment or would restrict future site or resource use, the public notice must specifically identify the restrictions and invite comments on these elements of the cleanup plan. This notice must also include a statement indicating the availability of public participation grants.

(3) Additional opportunities. To promote effective and meaningful public participation, ecology may provide or require public participation opportunities in addition to those specifically required under this chapter. In making this determination, ecology may consider:

(a) Known or potential risks to human health and the environment that could be avoided or reduced by providing information to the public;

(b) Public concerns about the site;

(c) The need to contact the public in order to gather information about the site;

(d) The extent to which the public's opportunity to affect subsequent ecology decisions at the site may be limited or foreclosed;

(e) The need to prevent disclosure of confidential, unverified, or enforcement-sensitive information;

(f) The routine nature of the contemplated remedial action;

(g) Interest in expediting remedial action at the site; and

The evaluation must include an identification of the potentially affected vicinity for the remedial action. For sites where site-specific risk assessment is used, ecology will also evaluate public interest in the site, significant public concerns regarding future site use, and public values to be addressed through the public participation plan.

(9) Public participation plans. For ecology-conducted and ecology-supervised remedial actions, except emergency remedial actions, ecology will ensure that a public participation plan is developed and implemented.

(a) Purpose and scope. A public participation plan is intended to encourage a coordinated and effective public involvement tailored to the public's needs at a site, and facilitate equitable participation by the public. The scope of the plan must be commensurate with:

(i) The threats posed by the site to human health and the environment, including likely vulnerable populations and overburdened communities;

(ii) The level of public concern regarding the threats; and

(iii) The nature of the proposed remedial actions to address the threats.

(b) Early planning encouraged. In order to develop an appropriate plan, ecology or a potentially liable person or prospective purchaser (if submitting a plan to ecology) should engage in an early planning process to assess the public participation needs at the site, including the needs of likely vulnerable populations and overburdened communities. This process may include identifying and conferring with individuals, community groups, indigenous peoples, local governments, public agencies, or any other organizations that may have an interest in or knowledge of the site.

(c) Development. Ecology will develop the plan, or work with a potentially liable person or prospective purchaser to develop the plan.

(i) If a plan already exists for the site, ecology will consider whether the existing plan is still appropriate or whether the plan should be amended. For example, a plan originally developed to address a remedial investigation/feasibility study may need to be amended to address implementation phases.

(ii) Unless otherwise directed by ecology, a potentially liable person or prospective purchaser requesting an agreed order under WAC 173-340-530 or a consent decree under WAC 173-340-520 must submit a proposed plan as part of its request. If a plan already exists for the site, the potentially liable person or prospective purchaser may either resubmit the existing plan with any proposed amendments or submit an entirely new proposed plan. The proposed plan may be revised during the course of discussions on the agreed order or negotiations on the consent decree. The final plan may become part of the agreed order or consent decree.

(d) Contents. A public participation plan must include the following:

(i) Applicable public notice requirements and how these will be met, including:

(A) When public notice will occur;

(B) The length of the comment periods accompanying each notice; and

(C) The potentially affected vicinity and any other areas to be provided notice, to the extent known;

(ii) Information repositories. The plan should identify at least one location where the public can review information about the remedial action. Multiple locations may be appropriate;

(iii) Methods of identifying the public's concerns. Such methods may include interviews, questionnaires, meetings, contacts with community groups or other organizations that have an interest in the site, or establishing citizen advisory groups for sites;

(iv) Methods of addressing the public's concerns and conveying information to the public. These may include any of the methods listed in subsection (4) of this section;

(v) Coordination of public participation requirements. The plan should identify any public participation requirements of other applicable federal, state or local laws, and address how such requirements can be coordinated. For example, if the federal cleanup law applies to the proposed action, the plan should explain how the federal cleanup law and this chapter's public comment periods will be coordinated;

(vi) Amendments to the plan. The plan should outline the process for amending the plan. Any amendments must be approved by ecology; and

(vii) Any other elements that ecology determines to be appropriate for inclusion in the final public participation plan.

(e) Site-specific risk assessment. If the variables proposed to be modified in a site-specific risk assessment or alternative reasonable maximum exposure scenario may affect the significant public concerns regarding future land uses and exposure scenarios, then ecology will assure appropriate public involvement and comment opportunities will occur as identified in the public participation plan.

(f) Implementation. Ecology retains approval authority over the actions taken by a potentially liable person or prospective purchaser to implement the plan.
