Proposals aimed at cracking down on polluters and adding protections for undocumented immigrants were among the dozens of new measures set to fall on the City Council’s plate once aldermen return for the new year.

Fines would be increased for large industrial air polluters under a proposal (O2020-6200) introduced by Mayor Lori Lightfoot last week. If approved, the measure would allow the Department of Public Health to lodge larger fines on “industrial facilities and demolition contractors that create dust and risk the health and quality-of-life of residents.”
