AIR QUALITY ACTION DAY HAS BEEN DECLARED FOR SUSQUEHANNA VALLEY ON FRIDAY, JAN 23

 The Department of Environmental Protection has declared an air quality action day for Jan.23.
Tomorrow’s Forecast
Friday, Jan 23: 110 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Saturday, Jan 24: 81 AQI Moderate Particle Pollution (2.5 microns)
Current conditions: Clouds and fog are breaking up across the region as of 1 p.m. EST this Thursday afternoon. High pressure will slowly build into the area overnight tonight into Friday. We are concerned about very light winds near the surface as the high builds in with very little mixing expected. In addition, temperature inversions are likely to trap PM2.5 close to the ground. So for tonight, expect some clearing skies with very light winds. Fine particulate will increase into the code ORANGE range later on tonight as the temperature inversion develops. Low temperatures close to 20 degrees. Friday’s forecast: A PM2.5 Action Day will be declared for the day Friday as very light winds and some warming aloft will bring any mixing in the boundary layer to a halt. Code ORANGE concentrations of fine particulate are likely with this scenario. With some sunshine, afternoon temperatures will recover into the middle 30s. A storm system coming out of the deep South will then move northeastward towards us Friday night into Saturday, and with the current forecast track, we could be in line for a quick inch or so of snow during this period. Precipitation could briefly turn to a bit of rain by later Saturday morning as temperatures creep just above the freezing mark. While atmospheric mixing will be a little greater on Saturday, fine particulate concentrations will remain well into the moderate range. *** Extended forecast: The weather pattern will continue to be an active one as we move into the early part of next week. A clipper system will move eastward and affect the area later Sunday night into Monday with snow. Because the low is expected to track more to the south, precipitation could fall as all snow as cold air remains in place. Following this, a large area of high pressure builds in for Tuesday into Wednesday of next week with dry weather and light winds. Low moderate levels of PM will occur Sunday into Monday, but with high pressure building in next week with existing snow cover, we have to again be concerned with stronger inversions trapping fine particulates close to the ground.–McAuliffe

EPA to hold public hearings on new ozone standard

On November 26, the U.S. Environmental Protection Agency (EPA) proposed a new national ambient air quality standard for ozone, the most widespread air pollutant, and one of the most dangerous. The standards would set the official limit on how much ozone pollution is too much, and help inform the public when the air in their community is dangerous to breathe.

EPA will hold three public hearings on the proposed updates to the national air quality standards for ground-level ozone, also known as smog. EPA has proposed an ozone level within a range of 65 to 70 parts per billion to better protect American’s health and the environment, while taking comment on a level as low as 60 ppb. The agency estimates that the benefits of meeting the proposed standards will significantly outweigh the costs, preventing asthma attacks, heart attacks, missed school days and premature deaths, among other health effects.

The hearings will be held on Jan. 29 and Feb. 2, 2015. Each hearing will begin at 9 a.m. and continue until 7:30 p.m. local time.

Jan. 29: Arlington, Texas
Arlington City Hall
101 W. Abram Street
Arlington, Texas, 76010

Jan. 29: Washington

William Jefferson Clinton East building, Room 1153

Feb. 2: Sacramento, Calif.
California Air Resources Board
Byron Sher Auditorium
1001 “I” Street
Sacramento, CA 95814

The public may register to speak at a specific time at a hearing by contacting Eloise Shepherd at 919-541-5507 or shepherd.eloise@epa.gov. People may also register in person on the day of the hearing. EPA will accept written comments on the proposed standards until March 17, 2015. The agency will issue a final rule by Oct. 1, 2015.

Next CAB Community Meeting

The next community meeting of the Clean Air Board will be on Jan. 8, 2015, at 7 pm.  We will be meeting at the Second Presbyterian Church, 528 Garland Drive in Carlisle.

No Clean Air Board meeting in December

The Clean Air Board will not be holding a community meeting in December.  The next community meeting of the Clean Air Board will be on Jan. 8, 2015, at 7 pm.  We will be meeting at the Second Presbyterian Church in Carlisle.

EPA proposes to revise ozone air quality standard

The Environmental Protection Agency (EPA) has  announced that it will make revisions to the primary and secondary NAAQS for ozone (O3) to provide requisite protection of the public health and welfare. The EPA is proposing to revise the primary
standard to a level within the range of 0.065 to 0.070 parts per million (ppm).  The current standard is 0.075 parts per million. EPA is required by law to periodically review and revise the public health standard to reflect the most recent scientific and medical information.  For more information, go to: http://nyti.ms/1uXDCIj
