Notice of Public Comment Period - Draft Annual Ambient Air Monitoring Network Plan for 2020

Wednesday, May 8, 2019

NOTICE OF SOLICITATION OF PUBLIC COMMENT

District of Columbia’s Draft Annual Ambient Air Monitoring Network Plan for 2020

Notice is hereby given that the District of Columbia’s (District) Draft Annual Ambient Air Monitoring Network Plan for 2020 is open for public comment before submittal to the U.S. Environmental Protection Agency (EPA) on July 1, 2019. 

The Clean Air Act mandates that ambient air quality surveillance systems in state and local jurisdictions, including the District, meet requirements specified in Title 40 of the Code of Federal Regulations (C.F.R.), Part 58.  Regulations require state and local monitoring agencies to conduct a periodic assessment of ambient air monitoring networks and propose any changes in an annual ambient air monitoring network plan. EPA established National Ambient Air Quality Standards (NAAQS) for six pollutants: ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), lead (Pb), and particulate matter less than 10 microns aerodynamic diameter (PM10) and less than 2.5 microns (PM2.5). These are commonly known as the “criteria” pollutants. When air quality does not meet the NAAQS, the area is said to be in “non-attainment” with the NAAQS. For more information on air quality and the federal NAAQS, please visit EPA’s website or DOEE’s Air Quality webpages.

DOEE is proposing to decommission one SO2 monitor at the River Terrace monitoring station due to redundancy with the trace SO2 monitor at NCore station at the McMillan Reservoir site. The Hains Point monitoring station has been temporarily shut down since July 10, 2017 due to a major building renovation project, which is still ongoing. Therefore, DOEE is permanently shutting down the Hains Point monitoring station and replacing it with the King Greenleaf Recreation Center monitoring station. The rest of the District’s ambient air monitoring network will be maintained as described in the Draft Network Plan in calendar year 2020.

The District’s Draft Annual Ambient Air Monitoring Network Plan for 2020 is available for review. A person may obtain a copy of the Plan by any of the following means:
