Air Monitoring

Invitation for Public Comments

The Rhode Island Department of Environmental Management (RIDEM) hereby gives notice of intent to submit an Exceptional Event Demonstration request to the Environmental Protection Agency (EPA) in accordance with Title 40 of the Code of Federal Regulations Part 50.14. The demonstration shows that a smoke plume from a Canadian Wildfire near Fort McMurray, Alberta, Canada adversely impacted ozone concentrations in Rhode Island.

On May 25 and 26, 2016, the Rhode Island Department of Environmental Management (RIDEM) recorded concentrations of ozone at the three state ozone monitors located in East Providence, West Greenwich, and Narragansett, that exceeded the 2015 Ozone National Ambient Air Quality Standards (NAAQS). The three monitors were affected by the smoke plume such that data from May 25 and May 26, 2016, should be excluded from regulatory determinations.

Proposed demonstration documents:
Exceptional Event Demonstration: Fort McMurray Wildfire, May 25 & 26, 2016 - Draft for comment
Exceptional Event Demonstration - Presentation

Instructions: The PowerPoint demonstration and the pdf document are intended to be used side by side. The pdf document will guide through the PowerPoint presentation, which should open as a slide show through which the user can navigate. References to content in the PowerPoint presentation will be made frequently, as indicated by “SLIDE#X”. Note: There are some animations requiring the left/right arrows or mouse clicks to toggle through the animation. Those animations will be labeled accordingly. Otherwise, GIF animations will play automatically.

Submit comments by May 26, 2017 on the proposed demonstration:

Did you know that RIDEM and RIDOH have partnered to monitor the air we breathe in Rhode Island going back to 1968? We are responsible for monitoring ambient air at 7 locations throughout Rhode Island. Watch and learn more!

 

Air Quality in Rhode Island; Why monitor the air?

  • To provide short and long term information regarding air pollution, YOUR health, and the air you breathe
  • To determine trends in the data that inform RIDEM which control programs and policies are making a difference and where to focus more attention
  • Measurements determine if Rhode Island is in compliance with Federal air quality standards
  • RIDEM has been tasked to fulfill monitoring requirements set forth by the Environmental Protection Agency

National Ambient Air Quality Standards (NAAQS)

Pollutant Averaging Time Primary Standard Secondary Standard
Sulfur Dioxide (SO2) 3-HourA None 0.5 ppm (1300 μg/m3)
1-HourB 0.075 ppm (75 ppb) None
Carbon Monoxide (CO) 8-HourA 9 ppm None
1-HourA 35 ppm None
Ozone (O3) 8-HourC 0.070 ppm (70 ppb) Same as Primary Standard
Nitrogen Dioxide (NO2) Annual Arithmetic Mean 0.053 ppm (53 ppb) Same as Primary Standard
1-HourD 100 ppb None
Particulate Matter ≤ 10 micrometers (PM10) 24-HourE 150 μg/m3 Same as Primary Standard
Particulate Matter ≤ 2.5 micrometers (PM2.5) Annual Arithmetic Mean F 12.0 μg/m3 15.0 μg/m3
24-HourG 35 μg/m3 Same as Primary Standard
Lead (Pb) Rolling 3-Month AverageH 0.15 μg/m3 Same as Primary Standard

  • Primary standards protect against adverse health effects.
  • Secondary standards protect against welfare effects such as damage to crops, vegetation, and buildings.
