This month CAB will be discussing our recent participation in the Clarke Forum panel on warehouse development, and hearing from citizens with ideas on clean air and forestry practices along Route I-81. Come share your thoughts, too! The Clean Air Board will be meeting on Tuesday, Feb. 25, at 7 pm at the Second Presbyterian Church, at 528 Garland Drive, Carlisle.

|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

|A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Saturday, Feb 1|
|Saturday, Feb 1:||110 AQI||Unhealthy for Sensitive Groups||Orange||Particle Pollution (2.5 microns)|
|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. ***|
On January 30, Dickinson College’s Clarke Forum will host a panel discussion on the complex array of environmental and economic-development issues surrounding the evolution of the Carlisle area as a major logistics center with the associated construction of mega-warehouses and the concentration of truck traffic.

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 Pennsylvania Department of Environmental Protection has declared an air quality action day for Dec. 4.
|Wednesday, Dec 4:||110 AQI||Unhealthy for Sensitive Groups||Particle Pollution (2.5 microns)|
|Current Conditions as of 1 PM on Tuesday: Hazy conditions continue this afternoon as calm winds are keeping mixng to a minimum, allowing for PM 2.5 levels to remain in the Code Orange range. Similar conditions will continue tomorrow before we begin to see a more active pattern return late week. *** Wednesday’s Forecast: Light winds will limit vertical mixing, yet again, through at least the morning and into the afternoon on Wednesday. Increasing moisture will continue to slowly push northward, bringing some milder temperatures with it. The combination of minimal mixing and rising moisture will allow for PM 2.5 levels to remain inside the Code Orange range through at least the middle of the day. The air mass to our south that contains the higher moisture levels is slightly cleaner than the current air mass in place. Therefore, as this air mass begins to push further north we should see concentrations begin to fall and reach the lower end of the Code Orange range if not high moderate by late in the day. A southerly breeze at the surface will form late afternoon to early evening to assist in pushing this mild and humid air mass northward. As a result, there will be enough hours of Code Orange concentrations throughout the day before we see improvement back to more moderate levels by late evening.
