ST. PAUL, MN (KDAL) – Duluth Ready Mix Concrete has agreed to pay a 12,300 dollar penalty to the Minnesota Pollution Control Agency for stormwater violations at its gravel pit in Canyon, about 35 miles northwest of Duluth.
An inspection of the facility in October of last year confirmed that the company did not adequately maintain a perimeter berm or immediately repair it when it failed.
The failed berm allowed significant and prohibited discharge of rock, sand and silt laden water to flow into a wetland area adjacent to the company property.
In addition to the civil penalty, the company had to remedy the discharges, repair and inspect the berm for stability, submit a pollution prevention plan and train staff to properly implement it.
