Warehouses As an Environmental Justice Issue
August 29, 2017
by Quan Yuan
When we think of locally undesirable land uses, we often think of large power plants, puffing single plumes of pollution. But many plumes of pollution from trucks traveling to and from warehouses can have equally large impacts on health. Read more …
Warehouses worsen local air pollution
Truck traffic associated with the facilities increases NO2 by 20%, study finds
August 7, 2024
Warehouses in the US worsen local air pollution, according to a new study. Using satellite data to study the air quality around nearly 150,000 warehouses, researchers found that nitrogen dioxide levels were 20% higher near warehouses, on average, compared to upwind locations mainly because of the trucks that frequent and idle at these facilities (Nat. Commun. 2024, DOI: 10.1038/s41467-024-50000-0). Read more . . ,
The PA Department of Environmental Protection is concerned about wildfire smoke from Canada drifting into Pennsylvania. Excerpts from PADEP message dated Aug. 4, 2025:
| A(n) Air Quality Action Day has been declared for Susquehanna Valley Area, PA, on Tuesday, Aug 5 | ||||
|---|---|---|---|---|
| Tomorrow’s Forecast | ||||
| Tuesday, Aug 5: | 102 AQI | Unhealthy for Sensitive Groups |  | Particle Pollution (2.5 microns) |
| 90 AQI | Moderate |  | Ozone | |
Thicker areas of low level smoke still persist to our north and there is concern some of this smoke works it’s way into the area Tuesday and Wednesday. Here are the forecast details:
*** Tuesday’s forecast: An Air Quality Action Day is in effect for Tuesday! Sunshine and a few clouds through near surface smoke Tuesday may result in several hours where PM2.5 concentrations move into the code ORANGE range. In addition, the smoke may act to produce ozone levels in the high moderate range for some time during the afternoon as well. Afternoon highs will reach the middle and upper 80s.
Any persons who are sensitive to air pollution should limit extensive outdoor exertion and visit www.airnow.gov for the latest air quality information in their location.
*** Extended forecast: Increasing clouds and an easterly flow will limit ozone production Wednesday and Thursday, but PM2.5 may still reach into code ORANGE for a time as the smoke may be slow to clear out, especially Wednesday.

At least 156 million Americans, about 46 percent of the population, live with unsafe levels of ozone, particulate pollution or both, according to the American Lung Association’s annual State of the Air report. See more

Current Conditions: At 5 p.m. EDT this Sunday afternoon, skies were mostly sunny with temperatures around 90 degrees. Ozone and fine particle (PM2.5) concentrations were in the moderate range. The heat will continue Monday, then things turn unsettled Tuesday into Wednesday with opportunities for much needed rainfall. Here are the forecast details: *** Monday’s forecast: AN AIR QUALITY ACTION DAY IS IN EFFECT FOR MONDAY!! Mostly sunny skies and temperatures in the lower to middle 90s will result in ozone maximums in the code ORANGE range during the afternoon. Sensitive persons are urged to limit outdoor activity during the afternoon hours. PM2.5 will remain in the moderate range through the day. *** Extended forecast: Better air quality is in store Tuesday into Wednesday as things turn more unsettled with the chance for showers and thunderstorms. Air quality will average in the upper good to perhaps low moderate range. The heat returns late this week with ozone concentrations again rising by Thursday.—McAuliffe |
* You are strongly encouraged to voluntarily help reduce air pollution when an Air Quality Action Day is declared.
* Here are some tips for reducing ozone pollution:
• Driving less by carpooling or using public transportation;
• Combining errands to reduce vehicle trips;
• Limiting engine idling;
• Refueling cars and trucks after dusk; and
• Conserving electricity by setting air conditioning to a higher temperature and turning off lights that are not in use.
* Here are some tips for reducing fine particulate matter (PM-2.5) pollution:
• 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.
* This air quality forecast was prepared by the Pennsylvania Department of Environmental Protection (DEP).
* The DEP’s air quality forecast for the Susquehanna Valley Area can also be found here.

Please join with CAB this Thursday for a presentation on the interaction of pesticides with biodiversity, disease, and climate – presented by Jay Feldman, Beyond Pesticides!
Topic: Eliminating petrochemical pesticides in our local environment
What: Join CAB online in this Zoom presentation
When: Thursday, Oct 19, at 7 p.m.
How: Reply to cleanairboard@gmail.com if you would like a link to the Zoom meeting.
March 27, 2023 – The Clean Air Board of Central Pennsylvania submitted comments to the US Environmental Protection Agency on proposed revisions to the air quality standards for fine particulate (soot). CAB urged EPA to tighten the standards to protect vulnerable populations and the general public. Recent medical studies have shown that even low levels of airborne soot pollution can cause harmful health problems. CAB asked EPA to adopt an annual standard of 8 micrograms per cubic meter (8 ug/m3) and a 24-hour standard of 25 micrograms per cubic meter (25 ug/m3). Read the CAB comments.
For every thousand people alive on earth, 973 are regularly inhaling toxins. Only 27 are not. Which means, almost certainly, you are too.
Last fall, the World Health Organization lowered its global air quality standard from 10 micrograms of particulate matter per cubic meter to five. Those terms and standards can feel abstract, which makes their meaning a bit hard to fathom. Read more . . .
