Aurora's Clean Air Act Requires 40 Factories Cut Emissions by 2030

Aurora’s City Council approved the Clean Air Compliance Act on Thursday, imposing binding emissions limits on 40 industrial facilities along the Riverway Corridor, the city’s manufacturing spine that employs roughly 18,000 residents. The legislation requires a 35 percent reduction in particulate matter by 2030, based on 2024 baseline readings from the city’s six air monitoring stations.

The rule targets the corridor’s older plants, many built before 1990, which account for nearly two-thirds of Aurora’s industrial emissions, according to the council’s own impact assessment. The legislation cites a 2025 Aurora Public Health Department study linking elevated asthma rates in the adjacent Riverside and Eastgate neighborhoods to fine-particulate exposure from those facilities.

Retrofits and a new training pipeline

The Act earmarks $12 million from the city’s Climate Resilience Fund for two main purposes: $8 million for low-interest loans to help plant owners install scrubbers and upgrade ventilation systems, and $4 million for a job-training partnership with Aurora Technical College. The college will launch a 12-week certificate program in industrial emission controls starting in January 2027, with capacity for 200 students per cohort. City officials say the program is projected to train 600 workers over three years, with a placement rate guarantee of at least 80 percent at local firms.

For residents, the most immediate change will be visible on the roads. The Act also mandates that Aurora Transit Authority add three express bus lines from Eastgate and Riverside to the Riverway industrial park by March 2027, funded by a separate $2.5 million allocation from the state’s Surface Transportation Block Grant. The bus routes are designed to reduce single-occupancy vehicle trips, which account for 22 percent of the corridor’s total emissions, per a 2025 city traffic study.

Costs and compliance timeline

Compliance costs for factory owners are expected to average $150,000 per facility, according to the council’s fiscal note. The loan program covers up to 75 percent of those costs, with repayment over 10 years at 2.5 percent interest. The remaining 25 percent, roughly $37,500 per plant, must come from owners’ own capital or private financing. The Aurora Chamber of Commerce has estimated that three smaller fabricators may need to consolidate operations to meet the new rules, though no job losses have been projected in the city’s official analysis.

The Act phases in enforcement over three years: an initial reporting period in 2027, a compliance deadline for 80 percent of facilities by 2029, and full enforcement, with fines of up to $10,000 per day per violation, starting January 1, 2030. A city-appointed oversight board, composed of two council members, two industry representatives and three community members from Riverside and Eastgate, will review annual progress reports and can grant one-year extensions to individual plants that demonstrate hardship.

The council’s next step is to issue requests for proposals for the bus-route contracts by August 15, with construction bids for the industrial retrofits’ pilot project, a new scrubber system at the city’s largest single emitter, the Aurora Metalworks plant, due by September 1. The first cohort of technical college students is scheduled to begin classes on January 11, 2027.
