      Sec. 25-68b. Definitions. As used in sections 25-68b to 25-68h, inclusive:

      (1) "Activity" means any proposed state action in a floodplain or any proposed state action that impacts natural or man-made storm drainage facilities that are located on property that the commissioner determines to be controlled by the state;

      (2) "Base flood" means that flood which has a one per cent chance of being equaled or exceeded in any year, as defined in regulations of the National Flood Insurance Program (44 CFR 59 et seq.) or that flood designated by the commissioner pursuant to section 25-68c. Any flood so designated by the commissioner shall have at least a one per cent chance of being equaled or exceeded in any year. Such flood may be designated as the A or V zones on maps published by the National Flood Insurance Program. The "base flood for a critical activity" means the flood that has at least a .2 per cent chance of being equaled or exceeded in any year. Such flood may be designated as the B zone on maps published for the National Flood Insurance Program;

      (3) "Commissioner" means the Commissioner of Environmental Protection;

      (4) "Critical activity" means any activity, including, but not limited to, the treatment, storage and disposal of hazardous waste and the siting of hospitals, housing for the elderly, schools or residences, in the .2 per cent floodplain in which the commissioner determines that a slight chance of flooding is too great;

      (5) "Floodplain" means that area located within the real or theoretical limits of the base flood or base flood for a critical activity;

      (6) "Flood-proofing" means any combination of structural or nonstructural additions, changes or adjustments which reduce or eliminate flood damage to real estate or improved real property, to water and sanitary facilities, and to structures and their contents;

      (7) "Freeboard" means a safety factor, expressed in feet above a calculated flood level, that compensates for unknown factors contributing to flood heights greater than the calculated height, including, but not limited to, ice jams, debris accumulations, wave actions, obstructions of bridge openings and floodways, the effects of urbanization on the hydrology of a watershed, loss of flood storage due to development and sedimentation of a watercourse bed;

      (8) "Proposed state action" means individual activities or a sequence of planned activities proposed to be undertaken by a state department, institution or agency, any state or federal grant or loan proposed to be used to fund a project that affects land use, or proposed transfer of real property belonging to the state.

      (P.A. 84-536, S. 1; P.A. 05-174, S. 1.)

      (7) To assist municipalities and state agencies in the development of comprehensive floodplain management programs;

      (8) To determine the number and location of state-owned structures and uses by the state in the floodplain and to identify measures to make such structures and uses less susceptible to flooding including flood-proofing or relocation;

      (9) To mark or post the floodplains within lands owned, leased or regulated by state agencies in order to delineate past and probable flood heights and to enhance public awareness of flood hazards;

      (10) To designate the base flood or base flood for a critical activity where no such base flood is designated by the National Flood Insurance Program. The commissioner may add a freeboard factor to any such designation;

      (11) To require that any flood control project be designed to provide protection equal to or greater than the base flood.

      (P.A. 84-536, S. 2; P.A. 95-230, S. 44, 45; P.A. 05-174, S. 2.)

      Sec. 25-68d. Certification of activity or critical activity within or affecting the floodplain. Exemption. (a) No state agency shall undertake an activity or a critical activity within or affecting the floodplain without first obtaining an approval or approval with conditions from the commissioner of a certification submitted in accordance with subsection (b) of this section or exemption by the commissioner from such approval or approval with conditions in accordance with subsection (d) of this section.

      (b) Any state agency proposing an activity or critical activity within or affecting the floodplain shall submit to the commissioner information certifying that:

      (1) The proposal will not obstruct flood flows or result in an adverse increase in flood elevations, significantly affect the storage or flood control value of the floodplains, cause an adverse increase in flood velocities, or an adverse flooding impact upon upstream, downstream or abutting properties, or pose a hazard to human life, health or property in the event of a base flood or base flood for a critical activity;

      (2) The proposal complies with the provisions of the National Flood Insurance Program (44 CFR 59 et seq.), and any floodplain zoning requirements adopted by a municipality in the area of the proposal and the requirements for stream channel encroachment lines adopted pursuant to the provisions of section 22a-342;

      (3) The agency has acquired, through public or private purchase or conveyance, easements and property in floodplains when the base flood or base flood for a critical activity is elevated above the increment authorized by the National Flood Insurance Program or the flood storage loss would cause adverse increases in such base flood flows;

      (4) The proposal promotes long-term nonintensive floodplain uses and has utilities located to discourage floodplain development;

      (5) The agency has considered and will use to the extent feasible flood-proofing techniques to protect new and existing structures and utility lines, will construct dikes, dams, channel alterations, seawalls, breakwaters or other structures only where there are no practical alternatives and will implement stormwater management practices in accordance with regulations adopted pursuant to section 25-68h; and

      (6) The agency has flood forecasting and warning capabilities consistent with the system maintained by the National Weather Service and has a flood preparedness plan.

      (c) The commissioner shall make a decision either approving, approving with conditions or rejecting a certification not later than ninety days after receipt of such certification, except that in the case of an exemption any decision shall be made ninety days after the close of the hearing. If a certification is rejected, the agency shall be entitled to a hearing in accordance with the provisions of sections 4-176e, 4-177, 4-177c and 4-180.

      (d) Any state agency proposing an activity or critical activity within or affecting the floodplain may apply to the commissioner for exemption from the provisions of subsection (b) of this section. Such application shall include a statement of the reasons why such agency is unable to comply with said subsection and any other information the commissioner deems necessary. The commissioner, at least thirty days before approving, approving with conditions or denying any such application, shall publish once in a newspaper having a substantial circulation in the affected area notice of: (1) The name of the applicant; (2) the location and nature of the requested exemption; (3) the tentative decision on the application; and (4) additional information the commissioner deems necessary to support the decision to approve, approve with conditions or deny the application. There shall be a comment period following the public notice during which period interested persons and municipalities may submit written comments. After the comment period, the commissioner shall make a final determination to either approve the application, approve the application with conditions or deny the application. The commissioner may hold a public hearing prior to approving, approving with conditions or denying any application if in the discretion of the commissioner the public interest will be best served thereby, and the commissioner shall hold a public hearing upon receipt of a petition signed by at least twenty-five persons. Notice of such hearing shall be published at least thirty days before the hearing in a newspaper having a substantial circulation in the area affected. The commissioner may approve or approve with conditions such exemption if the commissioner determines that (A) the agency has shown that the activity or critical activity is in the public interest, will not injure persons or damage property in the area of such activity or critical activity, complies with the provisions of the National Flood Insurance Program, and, in the case of a loan or grant, the recipient of the loan or grant has been informed that increased flood insurance premiums may result from the activity or critical activity, or (B) in the case of a flood control project, such project meets the criteria of subparagraph (A) of this subdivision and is more cost-effective to the state and municipalities than a project constructed to or above the base flood or base flood for a critical activity. Following approval for exemption for a flood control project, the commissioner shall provide notice of the hazards of a flood greater than the capacity of the project design to each member of the legislature whose district will be affected by the project and to the following agencies and officials in the area to be protected by the project: The planning and zoning commission, the inland wetlands agency, the director of civil defense, the conservation commission, the fire department, the police department, the chief elected official and each member of the legislative body, and the regional planning agency. Notice shall be given to the general public by publication in a newspaper of general circulation in each municipality in the area in which the project is to be located.

      (e) The failure of any agency to comply with the provisions of this section or any regulations adopted pursuant to section 25-68c shall be grounds for revocation of the approval of the certification.

      (f) The provisions of this section shall not apply to any proposal by the Department of Transportation for a project within a drainage basin of less than one square mile.
