Hyperion Energy Center - Air Quality Monitoring
Air Quality Monitoring Data
The Department of Environment and Natural Resources (DENR) began operating three air monitoring sites in Union County at the beginning of 2009. The sites are located generally north and south of the proposed Hyperion Energy Center (See Map). DENR has collected three years of air quality data to determine rural background levels for criteria air pollutants and air toxic pollutants. The air monitoring sites are operated using EPA approved equipment and following EPA requirements for location, operation, and analysis. The raw data and real time hourly data are available to the public.
- DENR completed its review of the ambient air monitoring data for 2009 to 2011 and compared the data to the federal National Ambient Air Quality Standards for each air pollutant. The comparison indicates Union County’s air quality is better than the standards set by EPA. The comparison may be viewed here
- In July 2012, the DENR requested approval from EPA to close the Union County UC #3 Site and move the monitoring equipment for ozone testing to one of the other two Union County Sites. EPA approved the closing of the site and moving of the monitoring equipment on September 27, 2012. At the beginning of October the ozone sampling equipment was moved by the department from UC #3 to UC #1. The move of the equipment to UC #1 Site will allow the Department to continue to collect background and regional ozone concentration data in Union County. UC #3 was closed because during the last four years the sampling shelter had deteriorated beyond repair and now needs to be taken out of service.
