Sec. 26-303. Findings. Policy. The General Assembly finds that certain species of wildlife and plants have been rendered extinct as a consequence of man's activities and that other species of wildlife and plants are in danger of or threatened with extinction or have been otherwise reduced or may become extinct or reduced because of destruction, modification or severe curtailment of their habitats, exploitation for commercial, scientific, educational, or private use or because of disease, predation or other factors; that such species are of ecological, scientific, educational, historical, economic, recreational and aesthetic value to the people of the state, and that the conservation, protection and enhancement of such species and their habitats are of state-wide concern. Therefore the General Assembly declares it is a policy of the state to conserve, protect, restore and enhance any endangered or threatened species and essential habitat.

History: Pursuant to P.A. 11-80, “Department of Environmental Protection” was changed editorially by the Revisors to “Department of Energy and Environmental Protection” in Subdiv. (1), effective July 1, 2011.

Sec. 26-305. Program for the protection of endangered and threatened species. There is established a program for the protection of endangered and threatened species. The commissioner may conduct investigations of wildlife and plants in order to develop information relating to population, distribution, habitat needs, limiting factors, essential habitats, and other biological and ecological data to determine conservation and management measures necessary for their continued ability to sustain themselves successfully.

(P.A. 89-224, S. 3, 22.)

Sec. 26-306. Regulations. Determination of whether any native species is endangered, threatened or of special concern. List. Essential habitats identified. (a) The commissioner shall adopt regulations, in accordance with the provisions of chapter 54, establishing procedures for determining whether any native species is endangered, threatened or of special concern. In making such determination, the commissioner shall consider: (1) The destruction or threatened destruction, modification or curtailment of the habitat of the species; (2) overutilization of the species for commercial, recreational, scientific, educational or private purposes; (3) disease, predation or competition affecting the species; (4) the inadequacy of existing regulatory mechanisms to affect the continued existence of the species within the state; or (5) other natural or man-made factors affecting the continued existence of the species within the state.

(b) Not later than June 22, 1990, the commissioner shall adopt regulations, in accordance with the provisions of chapter 54, listing native wildlife and native plants that he has determined to be endangered or threatened species or species of special concern. Not later than June 22, 1991, the commissioner shall so adopt regulations to identify, where biologically feasible, essential habitats for endangered and threatened species.

(c) The commissioner shall adopt regulations in accordance with the provisions of chapter 54 to establish criteria to be included in a petition pursuant to section 4-174 to add or remove a species from the list of endangered or threatened species or species of special concern or to add or remove an area identified as an essential habitat for such species.

(P.A. 89-224, S. 4, 22.)

Sec. 26-307. Review. The commissioner shall review, at least every five years, the designation of species as endangered, threatened or of special concern, and areas identified as essential habitats to determine whether he should: (1) Add or remove any species from the list of endangered or threatened species or species of special concern; (2) change the designation from one category to another; (3) add or remove any area from the list of essential habitats for endangered or threatened species. The review of species that are listed as endangered by the United State Department of Interior shall be conducted, to the extent practicable, in conjunction with the periodic year review process of the Department of Interior pursuant to the Endangered Species Act.

(P.A. 89-224, S. 5, 22.)

Sec. 26-308. Treatment of species not listed as endangered or threatened as endangered or threatened species. (a) The commissioner may adopt regulations, in accordance with the provisions of chapter 54, to treat a species not listed as endangered or threatened pursuant to section 26-306 as an endangered or threatened species if he finds that: (1) Such species so closely resembles a species listed as endangered or threatened that enforcement personnel would have substantial difficulty in attempting to differentiate between it and the listed species; (2) the effect of such substantial difficulty is an additional threat to the endangered or threatened species; and (3) treatment of the unlisted species as an endangered or threatened species would substantially facilitate enforcement and further the policy state in section 26-303.

(b) The regulations may include a provision to allow a person to conduct an activity which affects a species that resembles an endangered or threatened species if the person can demonstrate to the commissioner that the activity does not affect the endangered or threatened species.

(P.A. 89-224, S. 6, 22.)

Sec. 26-309. State acquisition of essential habitat. Management. (a) The commissioner may acquire for and on behalf of the state, essential habitat, or interests therein, for the conservation of endangered, threatened, or species of special concern by gift, devise, purchase, exchange, condemnation or any other method of acquiring real property or an interest therein.

(b) The commissioner may enter into agreements with federal agencies, or political subdivisions of this state or other states, or with individuals or private organizations for administration and management of any program established and utilized for the conservation of endangered and threatened species and for management of any area identified as essential habitat for such species pursuant to section 26-306.

(P.A. 89-224, S. 7, 22.)

Sec. 26-310. Actions by state agencies which affect endangered or threatened species or species of special concern or essential habitats of such species. (a) Each state agency, in consultation with the commissioner, shall conserve endangered and threatened species and their essential habitats, and shall ensure that any action authorized, funded or performed by such agency does not threaten the continued existence of any endangered or threatened species or result in the destruction or adverse modification of habitat designated as essential to such species, unless such agency has been granted an exemption as provided in subsection (c) of this section. In fulfilling the requirements of this section, each agency shall use the best scientific data available.

(b) Each state agency responsible for the primary recommendation or initiation of actions on land or in aquatic habitats which may significantly affect the environment, as defined in section 22a-1c, shall ensure that such actions are consistent with the provisions of sections 26-303 to 26-312, inclusive, and shall take all reasonable measures to mitigate any adverse impacts of such actions on endangered or threatened species or essential habitat. The Secretary of the Office of Policy and Management shall consider the consistency of such proposed actions with the provision of said sections 26-303 to 26-312, inclusive, in determining whether or not an environmental impact evaluation prepared pursuant to section 22a-1b satisfies the requirements of sections 22a-1a to 22a-1h, inclusive, and regulations adopted pursuant to said sections.

(c) If the Secretary of the Office of Policy and Management, in consultation with the commissioner, determines that a proposed action violates subsections (a) or (b) of this section and there are no feasible and prudent alternatives the state agency may apply to the commissioner for an exemption. The commissioner may grant an exemption after considering the following factors: (1) The agency did not make an irreversible or irretrievable commitment of resources after initiation of consultation with the department that forecloses the opportunity for formulating and implementing feasible and prudent alternatives, (2) the benefits of the action clearly outweigh the benefits of alternative courses of action, consistent with conserving the species or its essential habitat, and such action is in the public interest, (3) the action is of regional or state-wide significance, and (4) the agency plans to take reasonable mitigation and enhancement measures necessary and appropriate to minimize the adverse impacts of the action upon the species or essential habitat, including, but not limited to, live propagation, transplantation, and habitat acquisition and improvement.

(d) If the Secretary of the Office of Policy and Management, in consultation with the commissioner, determines that a proposed action would not appreciably reduce the likelihood of the survival or recovery of an endangered or threatened species, but would result in the incidental taking of such species, the commissioner shall provide the state agency with a written statement that: (1) Specifies the impact of such incidental taking on the species; (2) specifies feasible and prudent measures and alternatives that shall be implemented as part of the proposed project in order to ensure that the action does not appreciably reduce the likelihood of the recovery of the species; and (3) sets forth terms and conditions including, but not limited to, reporting requirements to ensure compliance with this subsection. Any taking that is in compliance with the measures and alternatives specified pursuant to this subsection shall not be prohibited by sections 26-303 to 26-312, inclusive.

(b) Nothing in sections 26-303 to 26-312, inclusive, or any regulation adopted pursuant to said sections shall prohibit a person from performing any legal activities on his own land that may result in the incidental taking of endangered or threatened animal and plant species or species of special concern.

(c) Nothing in sections 26-303 to 26-312, inclusive, or any regulations adopted pursuant to said sections shall prohibit any action authorized pursuant to an exemption or permit provided for by the federal Endangered Species Act or in any regulation adopted under said act, or permit any action prohibited by the Endangered Species Act or by any regulation adopted under said act.

(d) Nothing in sections 26-303 to 26-312, inclusive, section 26-317 or any regulations adopted pursuant to said sections shall prohibit transportation through this state of any endangered or threatened species in accordance with the terms of any permit issued under the laws of another state provided the person in possession of an endangered or threatened species can prove legal possession of the species.

(e) The commissioner may prohibit, in an emergency, the taking of any state species of special concern threatened with undue depletion from overutilization of the species for commercial, recreational, scientific, educational or private purposes.

Sec. 26-313. Disclosure. Notwithstanding the provisions of the Freedom of Information Act, as defined in section 1-200, the Commissioner of Energy and Environmental Protection may withhold from disclosure to any person maps and records that disclose the location of any essential habitat or that disclose the location of any threatened species, endangered species, or species of special concern, upon determination that disclosure of such information to such person would create an unacceptable risk of destruction of, or harm to, such habitat or species. Prior to disclosure of any maps or records to any person, the commissioner may impose any reasonable conditions including the condition that the person to whom the information is disclosed furnish the commissioner with security in an amount and kind sufficient to guarantee that such person shall not destroy or harm, or cause to be destroyed or harmed, any such habitat or species. Any person whose request for disclosure has been denied shall be afforded the opportunity for a hearing to establish (1) that the requested information should be disclosed because disclosure would not create an unacceptable risk of destruction of, or harm to, such habitat or species, and (2) the unreasonableness of any condition imposed, including the amount or kind of any security to be established. Any hearing or other proceeding pursuant to this section shall be held in accordance with the provisions of chapter 54.
