If the owner or operator of facility receives any such notice, then the provisions of subdivision (5) of this subsection shall thereafter apply to all investigation and remediation activities undertaken and all subsequent investigation and remediation at any such facility shall be overseen by a licensed environmental professional.

(7) Public Participation

(A) Prior to the commencement of any remedial action undertaken pursuant to this subsection, the owner or operator of a disposal facility shall provide public notice of the proposed remediation in accordance with the schedule submitted pursuant to this subsection or an alternative schedule approved by the commissioner. Any such notice shall summarize the investigations undertaken, the results of the investigations and clearly identify the proposed remediation activities. The notice shall also include an address, telephone number for an office and contact person from which any interested person may obtain additional information about the investigation undertaken and the proposed remediation, including but not limited to, access to all the scopes of work, plans, reports, sampling, analysis, and sampling results regarding the investigation undertaken at the facility and the consideration, if any, of alternative remedial actions. The notice shall also provide that comments of the proposed remediation may be submitted to the commissioner within forty-five days of the publication or mailing of such notice.

The owner or operator shall:

(i) publish such notice in a newspaper having a substantial circulation in the municipality in which the disposal facility is located and the municipality or area affected by the facility;

(ii) provide a copy of the notice to the director of health of the municipality where the disposal facility is located;

(iii) provide a copy of the notice to all persons on the facility mailing list maintained pursuant to 40 CFR 124.10(c)(1)(ix); and

(iv) either (I) erect and maintain for at least thirty days in a legible condition a sign not less than six feet by four feet at the facility, which sign shall be clearly visible from the public highway, and shall include the words "ENVIRONMENTAL CLEAN-UP IN PROGRESS AT THIS SITE. FOR FURTHER INFORMATION CONTACT:", including a telephone number for an office from which any interested person may obtain additional information about the remediation, or (II) mail a copy of the notice to each owner of record of property which abuts the facility, at the address for such property on the last-completed grand list of the municipality where the facility is located.

(B) The commissioner shall forward a copy of all comments received by the date specified in the public notice on the proposed remediation, and all comments made at a public hearing, to the owner or operator of the facility. The owner or operator shall, within sixty days of receiving such comments, submit to the commissioner a written summary of all such comments and a written response to each such comment. The commissioner shall review such summary and responses and shall adopt it as his own, adopt it with modifications, or reject it and prepare a summary of and response to each comment. The commissioner shall send a copy of the summary and responses to comments and his action with respect thereto to each person who submitted comments on the remediation proposal.

(C) If the commissioner determines that there is substantial public interest in any remediation proposed pursuant to this subsection, he may hold a public meeting on such proposed remediation, and he shall hold a meeting upon receipt of a petition signed by twenty-five or more persons. Notice of any such meeting shall be given in the manner prescribed by subparagraph (A) of this subdivision. Any such meeting need not be conducted pursuant to the provisions of chapter 54 of the Connecticut General Statutes.

(8) The investigation and remediation required under this subsection shall, at a minimum, be equivalent to that specified for corrective action in 40 CFR 264.101 and the commissioner shall, to the extent feasible, ensure that any such investigation and remediation is consistent with investigation and remediation undertaken under other state programs. Nothing in this subsection, however, shall relieve an owner or operator from any other obligation imposed by law, including but not limited to, any obligation imposed under the state's hazardous waste management regulations, including any closure or post-closure obligation; or any requirement imposed under sections 22a-133k-1 to 22a-133k-3, inclusive, of the Regulations of Connecticut State Agencies.

(9) Upon request by the commissioner, the owner or operator shall submit to the commissioner copies of technical plans, reports, analytic results of any other information related to investigation and remediation of a facility undertaken pursuant to this subsection. Unless the Commissioner specifies another period of time, the owner or operator shall submit the information requested by the Commissioner within thirty days of the Commissioner's request.

(10) Disposal Facilities Also Subject to Section 22a-134 to 22a-134e of the Connecticut General Statutes, inclusive.

(A) Investigation. Except as provided for in this subparagraph, an owner or operator who is performing or has completed an investigation of a disposal facility pursuant to sections 22a-134 to 22a-134e of the Connecticut General Statutes, inclusive, (commonly known as the "Transfer Act") shall be deemed to be satisfying or have satisfied the requirement to investigate such disposal facility as required by this subsection. The foregoing shall apply, however, only to that portion of a disposal facility at which an investigation is being performed or has been completed under the Transfer Act. If for any reason, including but not limited to, a review of the investigation undertaken at such disposal facility, or comments received pursuant to 40 CFR 270.73, the Commissioner determines that any such disposal facility, or any portion thereof, is not being investigated or has not been investigated in accordance with prevailing standards or guidelines or any other requirement of the Transfer Act or that the investigation undertaken is not sufficient to identify the nature and extent of all releases of hazardous waste and hazardous substances at or from such disposal facility, the owner or operator shall not be deemed to have satisfied the requirements of this subsection and shall perform the investigation required by this subsection. The Commissioner will notify the owner or operator in writing, pursuant to subdivision (4) of this subsection, if he determines that further investigation of a disposal facility is required and shall include the basis for any such determination in any such notification.

(B) Remediation. Except as provided for in this subparagraph, an owner or operator who is completing or has completed remediation of a disposal facility pursuant to sections 22a-134 to 22a-134e of the Connecticut General Statutes, inclusive, (commonly known as the "Transfer Act") shall be deemed to be satisfying or have satisfied the requirement to remediate such disposal facility as required by this subsection. The foregoing shall apply, however, only to that portion of a disposal facility at which remediation is actually being performed or has been completed under the Transfer Act. If for any reason, including but not limited to, a review of the remediation undertaken at any such disposal facility, or comments received pursuant to 40 CFR 270.73, the Commissioner determines that that any such disposal facility, or any portion thereof, is not being remediated or has not been remediated in accordance with the remediation standards or any other requirement of the Transfer Act or that the remediation undertaken is not protective of human health or the environment, the owner or operator shall not be deemed to have satisfied the requirements of this subsection and shall perform the remediation required by this subsection. The Commissioner will notify the owner or operator in writing, pursuant to subdivision (4) of this subsection, if he determines that further remediation of a disposal facility is required and shall include the basis for any such determination in any such notification.

(C) Nothing in this subdivision shall exempt an owner or operator from the requirement to submit an ECAF under subdivision (3) of this subsection.

(11) Nothing is this subsection shall affect the authority of the Commissioner under any other statute or regulation, including, but not limited to, the authority to issue any order to prevent or abate pollution or potential sources of pollution.
