For the purpose of operating as an authority as provided in this article, powers, authorities, and privileges of the authority shall include, but are not limited to, the following:
The Public Service Commission shall act on all proposals submitted hereunder by an authority that provides only water service or only wastewater service, or by an authority that does not seek a rate increase within 120 days of the date that the authority files with the Commission a complete application. Failure of the Public Service Commission to act within the 120-day period shall be deemed an approval of such proposal: Provided, That the Commission's 120-day review period may be extended upon request of the authority.
The Public Service Commission shall act on all proposals submitted hereunder for which the authority seeks a rate increase and the authority provides water and wastewater services, water and stormwater services, wastewater and stormwater services, or water and wastewater and stormwater services, within 180 days of the date the authority files with the Commission the necessary information showing the basis of any project related rates, fees, and charges or other information as the Commission considers necessary: Provided, That the information shall include an explanation of the amount and basis for assigning and allocating total costs between the water operations, the wastewater operations, and if applicable the stormwater operations. Failure by the Commission to act within the 180-day period shall constitute approval thereof. Provided, however, That the 180-day Commission review period may be extended upon request of the authority.
