It took the state three decades to close 400 "orphaned" oil and gas wells.
But last year, the state plugged up more than 200.
Now, another six-million-dollars and matching state funding will help address the remaining 250 orphan wells.
Adam Wygant is the director of the oil, gas, and minerals division with the state.
"The finish line is in view in terms of getting all these wells plugged and then we'll turn our attention to addressing any legacy contamination that we found associated with these sites."
Wygant says work on remaining wells will take place across northern, central, and southeast Michigan.
