(a) The commissioner shall maintain a priority list of eligible water quality projects and shall establish a system setting the priority for making project grants, grant account loans and project loans. In establishing such priority list and ranking system, the commissioner shall consider all factors he deems relevant, including but not limited to the following: (1) The public health and safety; (2) protection of environmental resources; (3) population affected; (4) attainment of state water quality goals and standards; (5) consistency with the state plan of conservation and development; (6) state and federal regulations; (7) the formation in municipalities of local housing partnerships pursuant to the provisions of section 8-336f; and (8) the necessity and feasibility of implementing measures designed to mitigate the impact of a rise in sea level over the projected life span of such project. The priority list of eligible water quality projects shall include a description of each project and its purpose, impact, cost and construction schedule, and an explanation of the manner in which priorities were established. The commissioner shall adopt an interim priority list of eligible water quality projects for the purpose of making project grants, grant account loans and project loans prior to adoption of final regulations, which priority list shall be the priority list currently in effect under subsection (c) of section 22a-439.
(b) In each fiscal year the commissioner may make project grants, grant account loans and project loans to municipalities in the order of the priority list of eligible water quality projects to the extent of moneys available therefor in the appropriate accounts of the Clean Water Fund. Each municipality undertaking an eligible water quality project may apply for and receive a project grant and loan or project grants and loans in an amount equal to one hundred per cent of the eligible water quality project costs.
(c) The funding of an eligible water quality project shall be pursuant to a project funding agreement between the state, acting by and through the commissioner, and the municipality undertaking such project and shall be evidenced by a project fund obligation or grant account loan obligation, or both, or an interim funding obligation of such municipality issued in accordance with section 22a-479. A project funding agreement shall be in a form prescribed by the commissioner. Eligible water quality projects shall be funded as follows:
(1) A nonpoint source pollution abatement project shall receive a project grant of seventy-five per cent of the cost of the project determined to be eligible by the commissioner.
(2) A combined sewer project shall receive (A) a project grant of fifty per cent of the cost of the project, and (B) a loan for the remainder of the costs of the project, not exceeding one hundred per cent of the eligible water quality project costs.
(3) A construction contract eligible for financing awarded by a municipality on or after July 1, 2012, as a project undertaken for nutrient removal shall receive a project grant of thirty per cent of the cost of the project associated with nutrient removal, a twenty per cent grant for the balance of the cost of the project not related to nutrient removal, and a loan for the remainder of the costs of the project, not exceeding one hundred per cent of the eligible water quality project costs. Nutrient removal projects under design or construction on July 1, 2012, and projects that have been constructed but have not received permanent, Clean Water Fund financing, on July 1, 2012, shall be eligible to receive a project grant of thirty per cent of the cost of the project associated with nutrient removal, a twenty per cent grant for the balance of the cost of the project not related to nutrient removal, and a loan for the remainder of the costs of the project, not exceeding one hundred per cent of the eligible water quality project costs.
(4) If supplemental federal grant funds are available for Clean Water Fund projects specifically related to the clean-up of Long Island Sound that are funded on or after July 1, 2012, a distressed municipality, as defined in section 32-9p, may receive a combination of state and federal grants in an amount not to exceed fifty per cent of the cost of the project associated with nutrient removal, a twenty per cent grant for the balance of the cost of the project not related to nutrient removal, and a loan for the remainder of the costs of the project, not exceeding one hundred per cent of the allowable water quality project costs.
(5) A municipality with a water pollution control project, the construction of which began on or after July 1, 2003, which has (A) a population of five thousand or less, or (B) a population of greater than five thousand which has a discrete area containing a population of less than five thousand that is not contiguous with the existing sewerage system, shall be eligible to receive a grant in the amount of twenty-five per cent of the design and construction phase of eligible project costs, and a loan for the remainder of the costs of the project, not exceeding one hundred per cent of the eligible water quality project costs.
