S.D. Codified Laws § 46A-1-84
The Board of Water and Natural Resources shall promulgate rules pursuant to chapter 1-26 to award grants, loans, or other forms of financial assistance to sponsors of solid waste management projects. The rules shall base the awarding of grants or loans on a project's reflection of the solid waste management policy and hierarchy established in § 34A-6-1.2, the proposed amount of local matching funds, technical merit, and need for funding assistance.
Grants or loans may be awarded for planning, construction, and operation of solid waste management and recycling facilities. Preference in awarding grants or loans shall be given for projects which reduce the cost and number of landfills through shared facilities or use of innovative or alternative techniques, which are high on the waste management policy hierarchy, which involve areas which are particularly subject to groundwater or surface water contamination, or which will reduce long-term operating, closure, or post-closure costs.
