Manganese was recently detected on the far southeast side of Chicago. This web page was prepared to provide information on manganese, its health effects and steps being taken by the City to address the situation. This page will be updated on a regular basis as more information becomes available.
What is manganese?
Manganese is a naturally-occurring substance. It is used to make steel and is found in several consumer products. It is also an essential nutrient and a small amount of it in the diet is important to stay healthy. But, at excess amounts it can be neurotoxic (harmful to the brain).
The City of Chicago is updating current Bulk Materials Regulations to ensure Chicago's laws meet the needs of our communities.
Under Section 2-112-160 of the Chicago Municipal Code, CDPH is authorized to issue rules and regulations to interpret or implement ordinances within CDPH’s purview.
On March 13, 2014, CDPH issued Final Rules for the Control of Emissions from the Handling and Storage of Bulk Material Piles (the “Bulk Material Regulations”). The regulations were issued following a 50-day public comment period in which the City received approximately 1600 pages of comments from more than 60 individuals and organizations. In addition to written comments, CDPH received verbal comments at a special public community hearing held on January 14, 2014, and at various stakeholder meetings held during the public comment period pursuant to the Guidelines for Stakeholder Communications. Copies of all written comments, as well as the Guidelines for Stakeholder Communications, a log and summary of such communications, and a transcript from the special public hearing, are available at www.cityofchicago.org/environmentalrules.
On April 18, 2018, CDPH issued proposed amendments to the Bulk Material Regulations, including new requirements for facilities that handle manganese-bearing materials. The City is currently accepting written comments on the proposed regulations and will schedule a public hearing in the coming weeks.
