For which the assumptions used in developing the Region 9 PRGs are applicable.(b)
Management in place. KRS 224.01-400(18)(b) shall apply to sites where the party or applicant will manage releases in place. The goal of management in place shall be to attain target risk levels at the point of exposure, and be protective of ecological health.1.
Management of the release shall include engineering and institutional controls amounting to containment of the release, and either elimination of exposure pathways, or reduction of exposure.2.
The party or applicant shall consider current and proposed land use in selecting the remedy. Proposed land use shall not be in conflict with local zoning codes and other applicable ordinances.3.
The party or applicant shall describe to the cabinet the method for maintenance of engineering and institutional controls, including:a.
Annual (or other approved frequency) inspections of the engineering and institutional controls, as approved by the cabinet in the corrective action plan;b.
Annual (or other approved frequency) certification to the cabinet that the engineering and institutional controls remain protective of human health, safety and the environment; andc.
A deed instrument containing an enforceable restrictive covenant which is transferable and is binding on current and subsequent property and recorded with the county clerk for the county in which the property exists. A copy of the restrictive covenant shall be filed with the cabinet.4.
If the target risk levels at the point of exposure will not be achieved by the proposed remedy, the party or applicant shall demonstrate to the cabinet the protectiveness of the remedy using the criteria listed in clauses a through h of this subparagraph. The cabinet shall place emphasis on criteria listed in clauses a through d of this subparagraph when evaluating the remedy selected.a.
The overall protection of human health and the environment;b.
The compliance with any other applicable requirements;c.
The long-term effectiveness and permanence of the remedial option;d.
The reduction of toxicity, mobility, or volume through the use of treatment;e.
The short-term effectiveness of the remedy;f.
The ability to implement the remedy;g.
The cost of the remedy; andh.
Community acceptance of the remedy.5.
If the proposed remedy will not achieve target risk levels at the point of exposure the party or applicant shall provide a public notice of the remedy, including a summary of the contamination at the site, the remedial actions taken, and the residual risks associated with the site. The cabinet shall receive public comments on the proposed remedy for at least thirty (30) days following publication of the notice. For VERP participants, the public notice and comment period required by KRS 224.01-524 shall serve as the required public notice.(c)
Restoration. KRS 224.01-400(18)(c) shall apply to sites where the party or applicant restores the environment through removal of the contaminants of concern to ambient background levels, target risk levels at the point of exposure, or levels derived from a site-specific risk assessment approved by the cabinet, that do not require engineering or institutional controls.(d)
Combination of options. The party or applicant shall have the option to employ a combination of the remedial options described in this section.(4)
The cabinet shall review and approve or disapprove the corrective action plan pursuant to KRS 224.01-522 or 224.01-400(22), as applicable.Section 9.
Corrective Action Completion Report.(1)
The party or applicant shall submit to the cabinet a corrective action completion report.(2)
The corrective action completion report shall include:(a)
Documentation that the corrective actions implemented comply with the corrective action plan approved by the cabinet;(b)
Documentation of the completion of all the activities specified in the corrective action plan required in Section 7 of this administrative regulation, including documentation of any modification from the approved corrective action plan, documentation of the weight, volume, and classification of any material removed as part of the corrective action, copies of signed manifests and any other pertinent waste disposal forms, sampling procedures used for waste profile determination and restoration conformation, results from any confirmatory sampling and copies of all laboratory analytical reports, and information regarding backfill material, where it was obtained, and any attendant analytical results;(c)
Documentation of all engineering and institutional controls implemented to contain the release, eliminate pathways of exposure, reduce exposure, or achieve a combination thereof; and(d)
A statement signed by the party or applicant certifying that the document and all attachments were prepared under the party or applicant's direction or supervision, and the information submitted is, to the best knowledge of the party or applicant, true, accurate, and complete.(3)
The cabinet shall review and approve or disapprove the corrective action completion report pursuant to KRS 224.01-522 or 224.01-400(22), as applicable.Section 10.
