Our next Clean Air Board meeting will be on April 9, 2015. Join us at 7 pm at the Second Presbyterian Church, 528 Garland Drive, Carlisle, PA 17013
The Environmental Protection Agency (EPA) is required by law to review and adjust its public health standards for critical air pollutants every five years. This review is based on the latest scientific and medical information. Last November, EPA proposed to move to an 8-hour exposure standard for ozone between 60 and 70 ppb (parts per billion) in the ambient air.
The current public health standard is 75 ppb. If a new standard is adopted, the public would alerted to more “bad air” days — days during which the air quality is worse than the ozone standard. These air quality action days would occur during the warmer months, when pollutants bake in the atmosphere to form ground level ozone.
Our members include many people who suffer ailments from breathing polluted air. The Cumberland Valley is at the receiving end of an ozone transport corridor which originates hundreds of miles away. Even on days when an ozone alert has not been declared, people can and do suffer respiratory problems due to ozone.
In our letter to EPA, we highlighted some of the more recent scientific and medical studies supporting a more stringent ozone standard. Many of these studies have identified strong links between long-term and short-term exposure to ozone to specific health ailments; other studies have linked air pollution to death rates in certain areas, or have begun to assess the negative impact of air pollution on health care costs and economic productivity.
We support a more stringent 8-hour ozone exposure standard which would better protect our health.

|Air Quality Action Day has been declared for Susquehanna Valley on Mar 10|
|Tuesday, Mar 10:||105 AQI||Unhealthy for Sensitive Groups||Particle Pollution (2.5 microns)|
|Wednesday, Mar 11:||81 AQI||Moderate||Particle Pollution (2.5 microns)|
|Current Conditions: Our weather pattern has finally changed into something that more resembles March. High pressure is providing plenty of sunshine and milder air this Monday afternoon. Temperatures in many areas have moved past the 50 degree mark for the first time all year. Light winds with added warmth pushed fine particulate levels well into the moderate range this morning, but these concentrations are falling this afternoon with increasing winds. Overall, we will remain in the moderate range on average for today. Clear this evening, then clouds will increase and thicken later on tonight. Limited mixing and moisture advection will mean fine particulate levels rise into the code ORANGE range overnight. Low temperatures falling only into the lower 30s. ***Tuesday’s forecast: An Air Quality Action Day will be declared for Tuesday for elevated fine particulate concentrations. With plenty of low level moisture and near calm winds, concentrations should remain at code ORANGE levels through the day. Upper level flow from the southwest will send moisture our way in the form of rain later Tuesday afternoon and night. A little cooler than Monday with highs reaching into the lower to middle 40s. A shift in flow direction will turn the rain off later on Tuesday night, with fine particulate perhaps dropping some into the upper moderate zone.

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.

The public may register to speak at a specific time at a hearing by contacting Eloise Shepherd at 919-541-5507 or firstname.lastname@example.org. 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.
