Duluth Ready Mix Concrete Inc. has agreed to pay a $12,300 civil penalty to the Minnesota Pollution Control Agency (MPCA) for stormwater violations at its gravel pit in Canyon, about 35 miles northwest of Duluth.

An inspection of the facility last October confirmed that the company didn’t adequately maintain a perimeter berm, or immediately repair it when it failed. The failed berm allowed a significant and prohibited discharge of rock, sand, and silt-laden water to flow into a wetland area on and adjacent to the company’s property. The inspection also revealed that the company failed to implement and maintain a required pollution prevention plan from 2013 to 2019, and was late in submitting several required discharge monitoring reports to the MPCA.

In addition to the civil penalty, the company had to remedy its water-fouling discharges, repair and inspect the Canyon site’s berm for stability, submit a pollution prevention plan, and train its staff to properly implement the plan.

MPCA rules and regulations are designed to protect human health and the environment by limiting pollution emissions and discharges from facilities. When companies do not fully comply with regulatory requirements, the resulting pollution can be harmful to people and the environment.

When calculating penalties, the MPCA takes into account how seriously the violations affected the environment, whether they were first-time or repeat violations, and how promptly the violations were reported to authorities. The agency also attempts to recover the economic benefit the company gained by failing to comply with environmental laws in a timely manner.
