View *Updated* Memo w/ Graphs and Chart Here!
The Standing Rock Sioux Tribe (SRST) Department of Environmental Regulations /EPA office continues its recommendation that residents limit prolonged outdoor activities during smoky
conditions across Standing Rock, especially residents with known respiratory conditions.
Particulate matter, which consists of extremely small particles of soot and ash, have been
increasing across the area over the last several hours. Particulate matter can cause irritation
to the respiratory system, especially those who suffer from allergies, asthma or chronic
obstructive pulmonary disease (COPD). During this period of smoky conditions, the
Department recommends the elderly and young children to limit or completely avoid
unnecessary outdoor exposure.
The smoke in the area is resulted from wildfires in Canada and is expected to remain in the
area throughout the week. The Standing Rock EPA department will monitor the Air Quality
Index and update the alert as necessary.
