Section 6431 - Infectious waste disposal(a) It is hereby determined and declared that it is necessary for the health and welfare of the inhabitants of the State that the facilities and services of the Authority shall be used by all infectious waste generators within the State for the disposal of all infectious waste generated within the State, and the Authority may by regulation require all infectious waste generators, collectors and transporters therein to use the services and facilities of the Authority under such rules and regulations as the Authority shall fix and establish for the disposal of infectious waste; provided, however, that the infectious waste generators with on-site incineration for the disposal of infectious waste as of July 1, 1989, may continue to use such on-site incineration for the disposal of infectious waste generated on-site. The Authority, after public notice and hearing, may adopt rules and regulations requiring such infectious waste generators to report not less often than annually on the quantity and types of infectious waste incinerated on-site. This section shall not be construed, however, to affect or impair any contract entered into prior to July 1, 1989.(b) The Authority is directed to study, finance, design, develop, implement and operate, or cause the same to occur, an infectious waste incineration facility at the sites where it now owns and operates landfills in New Castle County, Kent County or Sussex County, or where it now owns and operates the Delaware Reclamation Project in New Castle County, or at such other site as it may select in accordance with this chapter. The Authority is hereby authorized to dispose of ash from any such infectious waste incineration facility in the Authority's landfills, subject to regulations promulgated by the Department of Natural Resources and Environmental Control. 67 Del.
