Air monitoring shelter to be set up at Grayson Lake monitoring site

The Division for Air Quality’s newest air monitoring shelter was delivered Thusday, and will be set up at our Grayson Lake monitoring site in the Ashland Regional Office.

Grayson Lake serves as a rural monitoring site for the Environmental Protection Agency’s National Air Toxics Trend Study.

The National Air Toxics Trends Station (NATTS) Network was developed to fulfill the need for long-term HAP monitoring data of consistent quality. Among the principle objectives are assessing trends and emission reduction program effectiveness, assessing and verifying air quality models (e.g., exposure assessments, emission control strategy development, etc.), and as direct input to source-receptor models.

The current network configuration includes 27 sites (20 urban, 7 rural) across the United States; 13 sites were established in 2003, 10 sites in 2004, and two sites each in 2007 and 2008. There are typically over 100 pollutants monitored at each NATTS.
