A law meant to clean Michigan’s air now costs the state billions with little oversight

March 19, 2026

Michigan has granted over $1. 2 billion in property tax exemptions to industrial companies over the past decade through a 1960s-era Air Pollution Control program intended to incentivize emissions reductions, but the program lacks meaningful oversight. Despite receiving these tax breaks, nearly half of the exempted facilities have violated air quality laws, yet the Michigan Department of Environment, Great Lakes and Energy claims it lacks resources to monitor compliance after granting exemptions.

Who is affected

Michigan municipalities and townships (specifically Detroit, Monroe, River Rouge, Port Sheldon)
Residents of affected communities (Port Sheldon loses $2,300 per resident annually; Monroe loses $1,734 per resident annually from DTE exemptions alone)
Industrial companies receiving exemptions (Consumers Energy, DTE Energy, Gerdau Special Steel, automotive manufacturers, coal plants)
Michigan State Tax Commission (three-person board granting exemptions)
Michigan Department of Environment, Great Lakes and Energy (EGLE)
Michigan Department of Treasury
U.S. Environmental Protection Agency

What action is being taken

BridgeDetroit reviewed 344 pollution control tax exemption certificates that manufacturers applied for since 2015
EGLE is negotiating a consent order with Gerdau to resolve violations alleged in an enforcement notice from 2022
Consumers Energy is working toward phasing out coal at power plants by 2032
Port Sheldon collected community feedback in 2024 to update its Master Plan and Economic Resiliency Plan

Why it matters

This matters because taxpayer-funded incentives designed to protect public health are not achieving their intended purpose while costing communities significant revenue. The program creates a troubling paradox where companies receive financial benefits for pollution controls they are often legally required to install anyway, yet face no consequences—such as losing exemptions—when they violate air quality laws. The lack of oversight means EGLE cannot adequately enforce environmental protections, raising broader concerns about Michigan's ability to safeguard air quality. Small municipalities are particularly vulnerable, losing revenue equivalent to critical infrastructure needs (like replacing lead water lines in River Rouge) while shouldering health impacts from pollution violations, yet having virtually no say in the exemption process or ability to hold violating companies accountable without costly court action.

What's next

EGLE is currently negotiating a consent order with Gerdau to resolve violations from 2022
Consumers Energy plans to phase out coal at power plants by 2032
Gerdau could receive additional penalties stemming from 2022 violations (currently under negotiation)
