(a) Program description. The intent of demonstration grants awarded under this section shall be to subsidize and support the implementation or operation of municipal solid waste demonstration projects. The purpose of supported demonstration projects shall be to illustrate, by example, the economic value and operational merit of a particular operation, system, or technology. This will in turn reduce the uncertainty inherent with investing in emerging, innovative, or alternative technologies, thereby indirectly encouraging larger scale application, participation, and/or acceptance by the public.(b) Eligible projects. Eligible projects shall be those that address any issue of municipal solid waste management. Projects must have potential application generally throughout the State of Texas, and not be so operationally unique as to only be applicable at the location where demonstrated. Priority will be given to projects that are judged as having a significant potential for implementation and/or economic viability. Grants may be used for the purchase, installation, operation, or maintenance of an approved demonstration project.(c) Participation frequency. Recipients shall be limited to one demonstration grant, issued under this section, during any specific contract performance period, unless specifically otherwise authorized in the published request for proposal.
