DEP Submits Pennsylvania’s 2010 Air Monitoring Network Plan to EPA

Tuesday, July 14, 2009

HARRISBURG -- Pennsylvania’s updated Ambient Air Monitoring Network Plan for 2010 has been finalized and submitted to the U.S. Environmental Protection Agency (EPA). The ambient monitoring network plan will assist DEP in its ongoing efforts to improve public health protection and better inform the public about air quality in their communities.

The Annual Air Monitoring Network Plan for 2010 includes plans to add continuous PM2.5 (particulate matter less than 2.5 microns in size) monitors to provide real-time data to the public and to support Air Quality Index (AQI) reporting. The plan explains the expansion of the existing air toxics monitoring capability and includes two new carbonyl air toxic monitors.
DEP indicates those facilities where air dispersion modeling will be used to locate source-oriented lead particulate samplers as part of implementing the new lead National Ambient Air Quality Standard. The department will continue to investigate continuous ammonia sampling equipment.

The network plan was available for a 30-day public comment period which closed on June 2. DEP has prepared a document that responds to the comments received. Both the 2010 network plan and the comments with responses are available on the DEP Web site at:

Although the formal comment period has ended, written comments are welcome at any time on the air monitoring plan. Comments should be sent to the attention of Jeffrey Miller, Chief, Division of Air Quality Monitoring, Bureau of Air Quality, P. O. Box 8468, Harrisburg, PA 17105-8468, or by email to Use “Annual Monitoring Network Plan” as the mail addressee or in the subject line.
