2017 Plan

Federal Regulations require States to submit to USEPA an annual air monitoring network plan for the prospective calendar year. The plan is to provide a detailed description of the monitoring network for all of the criteria pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), particulate matter (PM10 and PM2.5), and lead (Pb). Among other information, the plan is to include location information (address and latitude/longitude), site type, objectives, spatial scale, sampling schedule, and equipment type. In addition, changes from the previous network plan are to be listed.
