DEP Declares Code Orange Air Quality Action Day for Fine Particulate Matter for Thursday, January 13, 2022, in Multiple Areas of Pennsylvania
Harrisburg, PA – The Pennsylvania Department of Environmental Protection (DEP) has declared a Code Orange Air Quality Action Day for fine particulate matter for Thursday, January 13, 2022, in the following areas of Pennsylvania:
• The Philadelphia Area, which includes the counties of Bucks, Chester, Delaware, Montgomery, and Philadelphia;
• The Lehigh Valley-Berks Area, which includes the counties of Berks, Lehigh, and Northampton; and
• The Susquehanna Valley Area, which includes the counties of Cumberland, Dauphin, Lancaster, Lebanon, and York.
A moderately strong temperature inversion Thursday morning with calm or very light wind will likely contribute to daily average concentrations of fine particulate matter in the Code Orange range.
The U.S. Environmental Protection Agency’s (EPA) Air Quality Index (AQI) provides standardized color codes for forecasting and reporting daily air quality. Green signifies good air quality; Yellow means moderate air quality; Orange represents unhealthy pollution levels for sensitive groups of people; and Red warns of unhealthy pollution levels for all.
An Air Quality Action Day is declared when the AQI is forecasted to be Code Orange or higher. On an Air Quality Action Day, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.
Residents and businesses within the Air Quality Action Day areas are strongly encouraged to voluntarily help reduce fine particulate matter air pollution by:
• Reducing or eliminating fireplace and wood stove use;
• Avoiding the open burning of leaves, trash, and other materials; and
• Avoiding the use of gas-powered lawn and garden equipment.
PA DEP has extended the Code Orange Air Quality Action Day in the Susquehanna Valley to Monday, Nov. 8, 2021. According to the DEP news release, “An Air Quality Action Day will be declared for Monday as near calm winds and a strong morning inversion elevate PM2.5, especially prior to 10 a.m. The inversion will break with light north winds Monday afternoon, but parts of the area might still have PM2.5 daily averages in the code ORANGE range.”

DEP has declared an Air Quality Action Day for the Susquehanna Valley Area, PA, on Sunday, Nov 7.
According to the DEP news release, on Saturday evening, PM2.5 will be on the rise once more as a moderately strong inversion develops. *** Sunday’s forecast: An Air Quality Action day will be declared for the day Sunday with a strong inversion and calm winds early in the day. Winds will pick up from the north and northwest during the afternoon, but may not be sufficient enough to keep PM2.5 out of the code ORANGE range in a few locations.
Harrisburg, PA. An Air Quality Action Day for fine particulate matter will be in effect once again in the Susquehanna Valley for Wednesday, July 21. A cold front pushing to the south and east will improve conditions and help to move the wildfire smoke out of the area, but this feature will not arrive until the afternoon to early evening hours. A slight chance for showers and possibly a few thunderstorms will occur in advance of the arrival of this front, but these will not be widespread enough to help to clean out the air prior to the frontal passage.
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
• The southwestern counties of Allegheny, Armstrong, Beaver, Butler, Fayette, Washington, and Westmoreland.
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.

|A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Thursday, Jan 14|
|Thursday, Jan 14:||102 AQI||Unhealthy for Sensitive Groups||Particle Pollution (2.5 microns)|
|Friday, Jan 15:||66 AQI||Moderate||Particle Pollution (2.5 microns)|
|Current conditions: **An Air Quality Action Day is in effect for the day Thursday** After another morning of elevated fine particulate concentrations, levels are decreasing this Wednesday afternoon under a brisk west to southwest wind. Nonetheless, most locations will end up well into the moderate range. Fine particulate levels will increase overnight with a developing inversion and near calm winds. *** Thursday’s forecast: Fine particulate matter concentrations will be high Thursday morning, and there will not be enough afternoon mixing to keep levels out of the code ORANGE range, with the Lancaster area perhaps ending up with the highest concentrations. Skies should be partly sunny with a mild afternoon. *|
|A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Monday, Dec 21|
|Monday, Dec 21:||103 AQI||Unhealthy for Sensitive Groups||Particle Pollution (2.5 microns)|
|Tuesday, Dec 22:||40 AQI||Good||Particle Pollution (2.5 microns)|
|Current conditions: ***An Air Quality Action Day is in effect for Monday***. Calm to very light westerly winds, another strong morning inversion, and increasing weekday emissions from mobile and stationary sources will all act to create fine particulate concentrations in the code ORANGE range Monday. Fine particulate concentrations are expected to be at their highest during the morning hours. *|
|A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Sunday, Dec 20|
|Sunday, Dec 20:||103 AQI||Unhealthy for Sensitive Groups||Particle Pollution (2.5 microns)|
|Monday, Dec 21:||64 AQI||Moderate||Particle Pollution (2.5 microns)|
|Tuesday, Dec 22:||39 AQI||Good||Particle Pollution (2.5 microns)|
|Current conditions: An Air Quality Action Day is effect for the day Sunday. Stagnant surface winds, a moderately strong inversion, and snow cover will all act to bring fine particulate matter (PM2.5) concentrations to the code ORANGE range Sunday. Concentrations will be highest during the morning hours, and then fall some during the afternoon with a slight south wind. The day will turn out mostly cloudy with only a rain or snow shower. *** Monday’s forecast: Another weak weather system will bring a rain or snow shower later Monday or Monday evening with enough low level mixing from the south and southwest to where only moderate PM2.5 concentrations are expected. *** Extended forecast: Better air quality in the good range is expected by Tuesday, as a northwesterly flow will increase and be rather brisk in the afternoon. High pressure builds back in by Wednesday, but then a strong cold front brings rain to the area Christmas eve. A blast of very cold air will then follow for Christmas day and Saturday. Air quality should be in the good range Wednesday through Saturday.—McAuliffe|
