A federal judge has made a ruling that affects air quality in Harris County. The decision involves stricter limits on fine particulate matter, known as PM 2.5. This type of matter includes dust, smoke, and soot, which can be harmful to health.

The ruling requires the EPA to enforce these stricter limits on PM 2.5. This is the extent of the information available about the court's decision and its implications for the area.
