The South Dakota Department of Environment and Natural Resources (DENR) has developed its 2017 annual ambient air monitoring network plan, which is a review of the ambient air monitoring network as required by Title 40 of the Code of Federal Regulations (40 CFR), Part 58. The proposed plan is available it its entirety online, here. The department is planning the following modifications to the ambient air monitoring network plan in 2017 and 2018:

  • Continue to replace the old TA Series FH 62 C14 and old Met One BAM continuous particulate matter monitors with new particulate matter monitors as resources allow;
  • Evaluate the need to move the air monitoring site in Aberdeen, SD so air quality concentrations can be better characterized to determine:
    • Highest concentration for the area;
    • Improve location to evaluate the facilities with air quality emissions;
    • Allow the addition of continuous monitors to collect more data per year;
    • Alert the public when air quality concentrations exceed health impact levels; and
    • Continuous samplers so the public can view the current data on the DENR webpage and Environmental Protection Agency (EPA) AirNow site.

The plan is open for public review and comments through June 30, 2017. Comments can be submitted online, here.

Similarly, the North Dakota Department of Health (NDDoH) Division of Air Quality is soliciting public comment on its 2017 Ambient Air Quality Monitoring Annual Report.

  • NDDoH evaluated their existing monitoring network and made the following adjustments in 2016, by pollutant:
    • NOx:  Added in Bismarck, removed from Fargo
    • SO2 (trace level monitoring):  Added in Bismarck, removed from Fargo, TRNP-NU, Lostwood, Dunn Center
    • SO2 (standard):  Added in Fargo, TRNP-NU, Lostwood, Dunn Center
    • PM2.5:  Removed from Beulah, Fargo, Painted Canyon
  • In response to the requirement of 40 CFR 51.1203 (b) concerning characterization of 1-hour SO2 concentrations for the Tioga area, two new SLAMS-like monitoring sites were established in Williams County for operation in 2017.
  • NDDoH has deployed a broadband Spectroscopy PM analyzer at Bismarck to determine PM10, PM2.5 and PM10-2.5 concentrations. If this method is determined to be successful, NDDoH will consider the benefits of deploying more of these units throughout the network.
  • The current site of the monitoring station in the Dunn Center area is located on leased private land and future accessibility has been called into question. NDDoH has entered into an agreement with the U.S. Fish and Wildlife Service to allow a new air monitoring site to be located at the Lake Ilo National Wildlife Refuge. Initially, the Lake Ilo site will be operated concurrently with the Dunn Center station. Pending a review of a minimum of one quarter of valid data collection to show concurrence between the two stations, monitoring at the current Dunn Center site will end and the Lake Ilo site will be re-designated a SLAMS site. Monitoring is projected to begin at Lake Ilo in the first quarter of 2018.

The plan is open for public review, here, and comments can be mailed to the North Dakota Department of Health, Division of Air Quality, Data Collection and Analysis Branch, Air Monitoring Program, 918 E. Divide Avenue, Bismarck, ND 58501-1947, through July 5, 2017.
