DEP declares Air Quality Action Day for Friday, Jan. 15

Air Quality Action Day has been declared for Susquehanna Valley, PA, on Friday, Jan 15
Tomorrow’s Forecast
Friday, Jan 15: 105 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Saturday, Jan 16: 45 AQI Good Particle Pollution (2.5 microns)
Current Conditions: As of 2 PM on Thursday, mostly sunny skies prevail over the region as an area of high pressure across the southeastern Us dominates our weather. Right now, southwesterly winds coupled with the sunshine have allowed temperatures to climb into the upper 40s across the region. The combination of the warm air and the light winds across the area have allowed PM 2.5 levels to creep up into the moderate range. Expect levels to climb even higher tomorrow as a more stable air mass builds in for a good portion of the day. *** Friday’s Forecast: So for Friday, expect clear skies in the morning to give way to partly cloudy skies during the afternoon as we remain influenced by an area of high pressure. With the high building into the western Atlantic, expect the ridge to extend northwestward into the northern Mid-Atlantic region. At the same time, a new storm system will begin to take shape across the southeastern US. This system is slated to make its way up the East Coast later in the day. For much of the day, winds should be light over the region. Warmer air will continue to build in from the southwest aloft. It is these warmer conditions coupled with the light flow at the surface that will allow an inversion to form over the area. During the morning hours, the inversion is likely to fairly strong. As we move through the day, expect the inversion to break down as the surface temperatures warm (afternoon temperatures should peak in the mid 40s) and the storm approaches from the south. The intensity of the inversion during the morning hours along with the light winds will limit mixing within the boundary layer, allowing PM 2.5 levels to climb. With these kind of conditions persisting for much of the day, expect PM 2.5 levels to reach the Code ORANGE status, which is why we are issuing an Air Quality Action Day for PM 2.5.

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.

Air Quality Action Day declared for Susquehanna Valley on Thursday, Jan 7

Air Quality Action Day has been declared for Susquehanna Valley, PA, on Thursday, Jan 7
Tomorrow’s Forecast
Thursday, Jan 7: 105 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Friday, Jan 8: 100 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: As of 2 PM on Wednesday, sunny skies persist over the region as a ridge of high pressure remains centered across the eastern US. The persistence of this ridge over our area has contributed to light winds and a rise in temperatures today. In fact, temperatures are approaching the 40 degree mark. The combination of the light winds and warmer temperatures has also allowed PM 2.5 levels to rise into the moderate range. With even warmer air building in tomorrow, expect PM 2.5 levels to peak near the Code YELLOW / Code ORANGE threshold. *** Thursday’s Forecast: So for Thursday, expect mostly sunny skies to persist once again as the ridge of high pressure remains in place across the eastern US. This ridge will allow for clear conditions during the morning hours. The clear conditions will, in turn, allow the ground to radiatively cool, reducing temperatures into the 10s. With relatively no wind to speak of, expect there to be limited mixing near the surface, increasing PM 2.5 levels across the area. An inversion will remain in place for much of the day, keeping PM 2.5 levels elevated near the Code YELLOW / Code ORANGE threshold, even as temperatures rise into the low 40s. This is why an Air Quality Action Day for PM 2.5 has been issued for the Susquehanna Valley region of PA. ***

DEP declares Air Quality Action Day for Friday, Dec 11

A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Friday, Dec 11
Tomorrow’s Forecast
Friday, Dec 11: 104 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Saturday, Dec 12: 99 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: At 2 p.m. EST this Thursday afternoon, stagnant conditions persisted across the area with the sun finally breaking through in the past couple of hours. Fine particulate levels continue to be elevated across the area, with code ORANGE in a few locations. These conditions will continue into the day Friday as a strong inversion sets up later tonight and Friday morning. For tonight, we will have patchy cloudiness with areas of fog later on. Low temperatures will fall into the middle to upper 30s. Fine particulate matter will accumulate to the code ORANGE range overnight. *** Friday’s forecast: Fog and clouds will yield to sunshine by Friday afternoon, and things will be on the mild side, as temperatures approach 60 degrees. While there will be some mixing in the lower levels of the atmosphere Friday afternoon, it will not be enough to keep PM2.5 out of the code ORANGE range for an overall average. Clear to partly cloudy Friday night with another inversion developing. Lows only falling to near 40 degrees.

Air quality action day declared for Tuesday

 

DEP has declared Air Quality Action Day for Susquehanna Valley, PA, on Tuesday, Dec 8
Tomorrow’s Forecast
Tuesday, Dec 8: 102 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Wednesday, Dec 9: 94 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: At 2 p.m. EST this Monday afternoon, high pressure nearby continues to produce little wind and elevated levels of fine particulate. This will continue to be the case into the day Tuesday as we expect a inversion to develop overnight with near calm winds. A little mixing this afternoon has caused PM2.5 to drop some, but overall averages for today will average in the code ORANGE range. Tonight will be clear to start, then low clouds and areas of dense fog will roll in later on. Code ORANGE levels of fine particulate are again likely. ***Tuesday’s forecast: High pressure will maintain it’s grip on the area for the day Tuesday. It will be foggy to start, then sunshine will again return in most locations by the afternoon. A little mixing will occur in the afternoon, but will not be enough to keep fine particulate concentrations out of the code ORANGE range. High temperatures will be close to 50 degrees. ***

EPA’s ozone health standard – what it means for us

On October 1, the Environmental Protection Agency changed its  National Ambient Air Quality Standards (NAAQS) for ground-level ozone to 70 parts per billion (ppb), based on extensive scientific evidence about ozone’s effects on public health and welfare. The new standards are intended improve public health protection, particularly for at-risk groups including children, older adults, people of all ages who have lung diseases such as asthma.

The Clean Air Board actively participated in the EPA rule setting process, providing comments and testimony.  Learn how the new standard will be implemented in central Pennsylvania, and what we should do next.

Volkswagen’s “Clean Diesel” Emissions – What Went Wrong?

Recently, Volkswagen admitted that it had programmed its clean diesel engines to turn on full emissions controls only when the car was in test mode. This enabled VW diesel cars to pass emissions testing, but did not reflect real emissions during on-the-road driving conditions.  High nitrogen oxide emissions resulted, which was discovered by a West Virginia University researcher.

Kevin Stewart, American Lung Association’s Director of Environmental Health in the Mid-Atlantic Region, will explain how Volkswagen illegally bypassed emission controls and increased air pollution from these diesel vehicles.  Join us at our community meeting at Second Presbyterian Church, October 1, 7 pm.

Pennsylvania’s Department of Environmental Protection is holding listening sessions around the state to solicit comments about the EPA’s Clean Power rules, which were finalized this summer.  DEP would like to hear from you about your concerns and the means to achieve Pennsylvania’s targets for carbon reductions.  There is an upcoming listening session in York on Oct. 5, 2015,(2-5 pm) at  the Wyndham Garden, 2000 Loucks Road, York, PA  17408

Learn about the Clean Power Plan at our community meeting and tell us the points you want the Governor to hear if you cannot attend the DEP listening session.

DEP has declared Air Quality Action Day on Thursday, Sep 17

A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Thursday, Sep 17
Forecast
Thursday, Sep 17: 102 AQI Unhealthy for Sensitive Groups Ozone
66 AQI Moderate Particle Pollution (2.5 microns)

Extended Forecast
Friday, Sep 18: 74 AQI Moderate Ozone
61 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: At 2 p.m. EDT this Wednesday afternoon, high pressure over the Mid-Atlantic continues to bring sunshine with pleasantly warm temperatures to the region. With winds quite light, the air has stagnated some over the past couple of days, and this has allowed pollutants to build. Both fine particulate and ozone will be into the middle moderate range this afternoon. Mostly clear and comfortably cool tonight with lows in the upper 50s. *** Thursday’s forecast: There will be a good deal of sunshine on Thursday with another warm afternoon. Highs will reach the lower to middle 80s. With full sun, ozone levels will cross the code ORANGE threshold in the afternoon. Fine particulate will go well into the moderate range with the light southwest winds. Mostly clearThursday night with lows in the upper 50s. *** Extended forecast: While it will remain on the warm side on Fridaywith sunshine most of the time, winds will shift into more of a southeasterly direction, and this will keep ozone levels in the low to mid moderate range. Fine particulate will also remain at moderate levels. Highs will reach the lower to middle 80s once more. Sunshine and a few clouds Saturday. Continued warm with highs in the middle 80s. South to southeast winds will keep ozone and fine particulate from going above the moderate range. A cold front then crosses the region Saturday night. While this front will bring very little rain, it will mean an air mass change for Sunday into Monday. North to northeast winds behind the front will create enough mixing to finally clean the atmosphere out. An onshore flow may then continue into the early part of next week as high pressure gets situated over New England. This will mean more seasonable temperatures and better air quality.—McAuliffe
Here are some Air Quality Action Day tips you can follow to help reduce pollution:

Days when ozone levels are expected to be high:

* Conserve electricity and set your air conditioner at a higher temperature.
* Choose a cleaner commute—share a ride to work or use public transportation. Bicycle or walk to errands when possible.
* Refuel cars and trucks after dusk.
* Combine errands and reduce trips.
* Limit engine idling.
* Use household, workshop, and garden chemicals in ways that keep evaporation to a minimum, or try to delay using them when poor air quality is forecast.
