The Minnesota Pollution Control Agency (MPCA) and the Minnesota Department of Natural Resources (DNR) today announced a $1.375 million natural resource damages settlement agreement with Douglas Corporation. The damages are due to releases of per- and polyfluoroalkyl substance (PFAS) and hexavalent chromium that reached Bass Lake in St. Louis Park, and Bde Maka Ska and Lake Harriet in Minneapolis. Douglas Corp. has used both substances at its chrome-plating facility in St. Louis Park and is the alleged source.
At least $1 million of the settlement will be used to fund projects designed to improve water quality, fisheries, and outdoor recreational opportunities. The MPCA and DNR will manage the funds. Once Douglas Corp. completes payment to the State of Minnesota in early fall 2023, the DNR will connect with community partners for project ideas. The area eligible for projects is east of Highway 169 within the lower watershed of Minnehaha Creek, including but not limited to the affected lakes.
Douglas Corp., a chrome-plating facility at 3520 Xenwood Ave., uses PFAS and hexavalent chromium as part of its manufacturing process. The company previously used perfluorooctanesulfonic acid (PFOS), which is one type of PFAS.
The history leading up to this settlement includes:
- 2004: PFOS is detected in Bde Maka Ska, then known as Lake Calhoun.
- 2007: Minnesota Department of Health (MDH) issues initial fish consumption advisories due to PFOS in fish.
- 2008: MPCA’s investigation leads to the area stormwater system, Bass Lake in St. Louis Park, and Douglas Corp. Community water supplies in St. Louis Park and Minneapolis are not impacted.
- 2010: Douglas Corp. begins taking measures to prevent PFAS from leaving its facility, begins monitoring, and stops using PFOS.
- 2013: PFOS levels in fish found in Bde Maka Ska begin to fall — a sign of water quality improvement.
- 2016: Douglas Corp. agrees to a schedule of compliance that requires additional measures to protect the environment, including stormwater improvements, comprehensive monitoring, and stormwater pond cleanout.
- 2023: Settlement is reached for natural resource damages. The schedule of compliance remains in force.
While Bde Maka Ska and Lake Harriet remain on the state’s impaired waters list, water quality is improving. PFOS levels in largemouth bass from Bde Maka Ska fell about 90% between 2008 and 2021. The Minnesota Department of Health continues to recommend limiting fish consumption from these lakes due to PFOS. More information is found at the Minnesota Department of Health’s Fish Consumption webpage.
Minnesota’s PFAS Blueprint is the state’s comprehensive plan to prevent, manage, and clean up PFAS pollution. As part of the Blueprint, the MPCA announced the proactive PFAS Monitoring Plan in March 2022. Over 100 industrial and manufacturing facilities are included in the plan, including chrome plating facilities like Douglas Corp. The information collected will improve our understanding of PFAS pollution risks and prevention.
State 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.
