Community sewerage systems.

(b) If the association owning a community sewerage system fails to take any action in accordance with requirements of subsection (a) of this section, the municipal water pollution control authority may take any such action on behalf of the association or any other action within the powers granted to such authority which is necessary to ensure the effective operation of the system and to prevent pollution of the waters of the state. For the purposes of this section, the authority shall have the right to enter upon the properties and land subject to subdivision (3) of subsection (a) of this section. Except where delay would result in pollution of the waters of the state, no such action shall be taken unless the association has been given written notice ten days prior to any such proposed action, and has been afforded an opportunity to be heard on such proposed action. A municipal water pollution control authority may recover the cost of taking any action pursuant to this subsection by levying assessments, in the manner described in section 7-249 , or charges, in the manner described in section 7-255 , against the properties served by the system. Control over the operation, maintenance, repair and improvement of the system shall be returned to the association, or to a successor thereto, upon provision to the municipal water pollution control authority of adequate assurances that the requirements of subsection (a) of this section will be met, providing that nothing contained in this subsection shall limit the powers conferred on municipal water pollution control authorities by section 7-247 . Should the system be designed or intended to serve additional properties that subsequently are to be subject to subsection (a) of this section, such properties and the owner or owners thereof shall be subject to the provisions of this section in the same manner as were the properties held by the association or the members thereof. (c) Certification by a municipal water pollution control authority to the Commissioner of Energy and Environmental Protection, in a form satisfactory to the commissioner, that it will require a community sewerage system not owned by the municipality to be owned and managed in accordance with the provisions of subsections (a) and (b) of this section shall be sufficient for the municipal water pollution control authority to establish that it will ensure effective management of such system as required by subsection (b) of section 7-246 , provided that nothing contained in this section shall limit the power and duties conferred on the Commissioner of Energy and Environmental Protection by sections 22a-427 to 22a-438 , inclusive.
