Not later than October 31, 2011, the Commissioner of Public Health, in consultation with the Water Planning Council established pursuant to section 25-33o, shall prepare a list designating sources or potential sources of water that require protection so that the highest quality sources of water are available to provide water for human consumption. In preparing such list, the commissioner shall take into consideration the plans produced pursuant to sections 22a-352, 25-32d and 25-33h and such other plans or information that the commissioner deems relevant. The commissioner shall update the list annually or more frequently as the commissioner deems necessary. Nothing in this section shall be construed to limit the commissioner’s authority to approve a source of water supply that is not on the list.
