Dakota Aggregates has the OK to continue mining in Rosemount, Minnesota. The city council approved several mining permits, including a large-scale permit.
Under the permit, Dakota Aggregates will continue mining in the same southern area which it has mined since 2013. None of the additional uses on the site — aggregate processing, concrete product casting, and concrete and asphalt production — have permits that are up for renewal.
The current large-scale mining permit was most recently renewed in March 2016 after a review of noise issues on the mining site. At that time, the company took steps to mitigate noise by adding noise dampening materials to machines, moving equipment and increasing the size of the berms along the site, Dakota Aggregates representative Shaun Dahl said.
In July 2016 Dakota Aggregates conducted an additional sound study at the gravel operation, which showed the site was in compliance with Minnesota Pollution Control Agency sound standards.
After a public hearing in December, the Planning Commission unanimously recommended approving the permit, with the additional condition that Dakota Aggregates work with the city to conduct a sound test in the neighborhood north of the mining area sometime this spring.
