Sec. 19117. (1) The department shall establish a program to perform hydrogeological monitoring studies on open and closed sanitary landfills and open dumps owned by municipalities. The program shall determine the extent of groundwater contamination associated with the sanitary landfills and open dumps and the need for remedial actions on those sites. The department shall determine which landfills and dumps owned by municipalities are to be monitored. In determining the order in which the landfills and dumps owned by municipalities are to be monitored, the department shall consider the potential threat of human exposure to environmental contamination originating from the sanitary landfill or open dump and the likelihood that hazardous waste was accepted at the landfill or dump.

(2) The department shall not expend more than 10% of the total amount in the fund in any state fiscal year for the program to perform hydrogeological monitoring studies. The department shall not expend more than $50,000.00 for any single hydrogeological monitoring study performed under this section.
