Summary
The bill amends the Environmental Protection Act so the Illinois Pollution Control Board cannot adopt standards that are weaker than those already in its regulations and may adopt standards that are stricter than federal EPA rules. It covers air, water, drinking water, hazardous waste and landfills, affecting businesses, local governments and anyone needing environmental permits. The change ensures Illinois can enforce stronger environmental protections when needed.
