Notwithstanding any provision of sections 22a-449a to 22a-449i, inclusive, or any regulation adopted pursuant to said sections, except as provided for in subdivision (6) of this section, with respect to the investigation and remediation of a release, the underground storage tank petroleum clean-up program established pursuant to section 22a-449c shall be used to provide payment or reimbursement only when any of the following milestones are completed:
(1) A release response report prepared by an environmental professional, as defined in section 22a-133v, has been submitted to the commissioner which report describes: (A) All initial response actions taken that are necessary to prevent an on-going release and to mitigate an explosion, fire or other safety hazard resulting from the release; (B) the results of an initial site investigation that determines the presence and extent of free product from the release, the potential for or existence of groundwater pollution from the release which threatens the quality of drinking water well or wells, and whether the release has resulted in soil vapors or indoor air that threatens public health; and (C) all interim actions taken and proposed to remove such free product to the extent technically practicable, to provide potable water to any person whose drinking water has been polluted by a substance from the release which is above the groundwater protection criteria or above a level determined by the Commissioner of Public Health to be an unacceptable risk of injury to the health or safety of persons using such groundwater as a public or private source of water for drinking or other personal or domestic uses, whichever is more stringent, and to mitigate any risk to public health from polluted soil vapor or indoor air resulting from the release.
(2) An interim remedial action report approved, in writing, by a licensed environmental professional has been submitted to the commissioner or an interim remedial action report has been approved, in writing, by the commissioner. Such interim remedial action report shall describe in detail all interim remedial action taken to: (A) Remove free product to the maximum extent technically practicable; (B) ensure that all persons whose drinking water was polluted by the release have been provided potable water; and (C) ensure that soil vapors which pose a risk to public health are prevented from migrating into any overlying buildings.
(3) An investigation report and remedial action plan approved, in writing, by a licensed environmental professional has been submitted to the commissioner, or an investigation report and remedial action plan has been approved, in writing, by the commissioner. Such investigation report and remedial action plan shall include a detailed description of an investigation which determines the existing and potential extent and degree of soil, surface water, soil vapor and groundwater pollution, on and off-site, resulting from the release and describes all actions proposed to remediate soil, surface water, air or groundwater polluted by the release in accordance with the regulations adopted pursuant to section 22a-133k.
(4) A soil remedial action report approved, in writing, by a licensed environmental professional has been submitted to the commissioner, or a soil remedial action report has been approved, in writing, by the commissioner. Such soil remedial action report shall describe in detail the extent of soil pollution resulting from the release, all remedial actions taken to abate such soil pollution, and all documentation that demonstrates that such soil pollution has been remediated in accordance with the regulations adopted pursuant to section 22a-133k.
(5) A groundwater remedial action progress report approved, in writing, by a licensed environmental professional has been submitted to the commissioner or a groundwater remedial action progress report has been approved, in writing, by the commissioner. Such report may only be submitted after all construction necessary to implement the approved groundwater remedial actions has been completed and the groundwater remedial actions have been operated and monitored for one year. Such report shall include a detailed description of the remedial actions, the results of groundwater or any other monitoring conducted, an analysis of whether the remedial actions are effective, and a proposal for any changes in the groundwater remedial actions and monitoring that may be necessary to achieve compliance with the regulations adopted pursuant to section 22a-133k.
(6) An annual groundwater remedial action progress report approved, in writing, by a licensed environmental professional has been submitted to the commissioner or approved, in writing, by the commissioner. Such report shall include a detailed description of the remedial actions, the results of groundwater or any other monitoring conducted for the year covered by the report, an analysis of whether the remedial actions are effective, and a proposal for any changes in the groundwater remedial actions and monitoring that may be necessary to achieve compliance with the regulations adopted pursuant to section 22a-133k. A responsible party pursuant to section 22a-449f may submit to the commissioner up to, but not more than, four separate applications or requests for payment or reimbursement in a calendar year regarding costs, expenses or obligations paid or incurred concerning annual groundwater monitoring or compliance with this subdivision.
(7) A final remedial action report approved by a licensed environmental professional has been submitted to the commissioner, or a final remedial action report has been approved, in writing, by the commissioner, that documents that the release has been investigated in accordance with prevailing standards and guidelines and that the soil, surface water, groundwater and air polluted by the release has been remediated in accordance with the regulations adopted pursuant to section 22a-133k.
(8) The commissioner may adopt regulations, in accordance with the provisions of chapter 54, establishing milestones for investigation and remediation of releases or suspected releases from underground storage tank systems, including milestones that differ from those set forth in this section. Upon the adoption of such regulations, the milestones for investigation and remediation for which payment or reimbursement is available from the program shall be those set forth in the regulations.
(9) This section shall apply to an application or request for reimbursement or payment received by the commissioner on or after October 1, 2005, regardless of when the release or suspected release occurred, whether actions in response to the release or suspected release have already occurred or whether prior applications or requests seeking payment or reimbursement have already been submitted to the commissioner.
