Pennsylvania DEP has declared an Air Quality Action Day for Susquehanna Valley on Saturday, Feb 8

Tomorrow’s Forecast
Saturday, Feb 8: 110 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Sunday, Feb 9: 100 AQI Moderate Particle Pollution (2.5 microns)

Current Conditions as of 1 PM on Friday: Ample sunshine under blue skies is always a welcome sight, but temperatures once again remain several degrees below normal this afternoon. High pressure will continue to build and move overhead tonight and into the day on Saturday. A few weak disturbances will swing through the region over the course of the weekend, with little to no precipitation associated with them. *** Saturday’s Forecast: Mostly clear skies into the overnight and early morning hours will allow temperatures to fall into at least the teens once again tonight. With high pressure continuing to build and shift to more overhead on Saturday, winds will become light to calm for a good portion of the day. There have been a few occasions in the past that I can remember where an icy surface on snow cover under high pressure with calm winds near the surface has allowed PM 2.5 levels to reach Code Orange levels. Conditions appear favorable for this to occur once again on Saturday. A weak disturbance passing through the region may create a brief period of snow showers. This system will not have much moisture to work with, so the less snow that develops the better the chance that PM 2.5 levels do not fall enough to avoid Code Orange for the day. Highs on Saturday will approach the 30 degree mark.  – Roble

Days when particle pollution levels are expected to be high:
* Reduce or eliminate fireplace and wood stove use.
* Avoid using gas-powered lawn and garden equipment.
* Avoid burning leaves, trash and other materials.

This forecast is brought to you by the Pennsylvania Department of Environmental Protection (PA DEP) and the Air Quality Partnership of the Susquehanna Valley. 


DEP has declared an Air Quality Action day for the Susquehanna Valley for Saturday, Feb. 1

A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Saturday, Feb 1
Tomorrow’s Forecast
Saturday, Feb 1: 110 AQI Unhealthy for Sensitive Groups Orange Particle Pollution (2.5 microns)

Extended Forecast
Sunday, Feb 2: 79 AQI Moderate Particle Pollution (2.5 microns)
Monday, Feb 3: 69 AQI Moderate Particle Pollution (2.5 microns)
Tuesday, Feb 4: 63 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: As of 2 p.m. EST this Friday afternoon, warmer air has finally moved into the area. However, there has also been a corresponding increase in the levels of fine particulate. Most locations should end up in the upper moderate range this afternoon with very little wind. Code ORANGE levels of fine particulate are likely tonight into the day Saturday as very light to calm winds, a temperature inversion, and rising humidity levels keep pollutants trapped closer to the surface. Low temperatures overnight mainly in the middle 20s.   ***  Saturday’s forecast: Code ORANGE PM2.5 levels are likely on Saturday as winds remain light, with little mixing available for dispersion. Afternoon high temperatures will climb into the lower to middle 40s. Low levels of mixing will continue Saturday night with poor air quality.  ***

Next Clean Air Board Community Meeting in January

The Clean Air Board will be holding its next community meeting on January 9, 2014, at 7 pm at the Second Presbyterian Church in Carlisle.

Clean Air Board asks DEP to examine Regional Greenhouse Gas Initiative

At the invitation of the Pennsylvania Department of Environmental Protection, the Clean Air Board submitted comments on adopting state plans under the Clean Air Act to reduce carbon emissions.   On Dec. 9, 2013, the DEP held a listening session to hear from environmental organizations on how to implement Section 111(d) of the Clean Air Act, which would require state plans to curb carbon emissions once EPA adopts carbon emission limits for new power plants.

CAB’s comments urge DEP to look at the Regional Greenhouse Gas Initiative (RGGI) – undertaken by nine states (but not including Pennsylvania) – as a model for reducing carbon emissions.  According to RGGI: “The experience in the RGGI states shows the magnitude of emission reductions possible from the power sector: a projected 50% decline in tons of carbon dioxide (CO2) emissions and a fossil fuel-fired generation fleet that is projected to achieve emission rates on par with the recently proposed new source performance standard for new electric generating units.”

The meeting will be held at the Second Presbyterian Church, 528 Garland Drive, Carlisle, at 7 pm.

NBC News reports on link between air pollution and cancer

The International Agency for Research on Cancer declared on Thursday that air pollution is a carcinogen, alongside known dangers such as asbestos, tobacco and ultraviolet radiation. The decision came after a consultation by an expert panel organized by IARC, the cancer agency of the World Health Organization, which is based in Lyon, France.

“We consider this to be the most important environmental carcinogen, more so than passive smoking,” said Kurt Straif, head of the IARC department that evaluates cancer-causing substances.

IARC had previously deemed some of the components in air pollution such as diesel fumes to be carcinogens, but this is the first time it has classified air pollution in its entirety as cancer causing.
