US environmental regulators will review brick and clay factory pollution rules

The US environmental regulators are starting a review of air pollution rules for factories that make bricks, clay products, and ceramics. They will consider if the rules are still needed and if technology or economic conditions have changed.

This is a routine review required by law every ten years. It means the rules could get tighter, looser, or stay the same. For now, it just means factories that make bricks and clay products will have a chance to tell the government what they think about the current pollution limits.
