Harrisburg, PA – The Pennsylvania Department of Environmental Protection (DEP) has issued a Code Orange Air Quality Action Day for fine particulate matter for Tuesday, July 20, 2021, in the following areas of Pennsylvania:

• The southeastern counties of Bucks, Chester, Delaware, Montgomery, and Philadelphia;
• The Lehigh Valley-Berks Area which includes the counties of Berks, Lehigh, and Northampton;
• The southcentral counties of Cumberland, Dauphin, Lancaster, Lebanon, and York; and

Smoke from wildfires in northern and western Canada, along with light winds, will likely contribute to daily average concentrations of fine particulate matter in the Code Orange range on Tuesday.
