Approximately 90 percent of emissions come from Cache County
By ROBERT S. MERRILL
Approximately 20 people attended a public information/ public hearing meeting on Thursday to gather input on a draft Cache Valley air quality improvement plan drafted by Idaho’s Department of Environmental Quality.
DEQ airshed coordinator Melissa Gibbs told the group prior to the hearing that extensive modeling of the proposed plan shows clean air standards can be achieved by 2014.
The plan is entitled “Cache Valley Idaho PM2.5 Nonattainment Area State Implementation Plan.” It demonstrates how the area will comply with the national ambient air quality standard for fine particulate matter referred to as PM2.5, she said.
Exposure to fine particles is linked to a variety of serious health problems including decreased lung function, chronic bronchitis, aggravated asthma, irregular heartbeat, non-fatal heart attacks and premature death in people with heart or lung disease, she explained.
She said based on monitoring data it has been determined Cache Valley, spanning Idaho and Utah, has failed to meet the 24-hour standard for PM2.5. Contributing factors include wood stove emissions, vehicle emissions and mobile dust.
