Purpose — The Annual Network Plan (ANP) provides information on each site within the West Virginia Department of Environmental Protection, Division of Air Quality’s (DAQ’s) ambient air quality network. If necessary, the ANP includes documentation of any changes to the state’s PM2.5 monitoring that would affect the location of a violating PM2.5 monitor. It should be noted that there are no PM2.5 monitors in West Virginia that currently violate either the 24-hour or annual National Ambient Air Quality Standard. All monitoring sites are leased and those leases are subject to periodic renewals which can affect the DAQ’s ability to retain a monitoring site location.

Overview — This ANP covers operations during 2020 as well as proposed changes for 2021. The MAP in the Report shows all known air quality monitoring sites in West Virginia using FRM/FEM monitors. DAQ operated 18 sites across the state in 2020, and plans to operate 17 sites in 2021. Though shown on the map, DAQ is neither the operator nor the Primary Quality Assurance Organization for the two (2) SO2 DRR monitoring sites or for the two (2) CASTNET sites. The SO2 DRR site in Mineral County was discontinued in 2020.

The Table in the Report provides summary information on all of DAQ’s air monitoring sites that operated in 2020. While the Chester site operated until March 2020, it is not planned to be operated in 2021; there will be 17 sites operating monitors statewide in 2021.
