☷ Erie Colorado - June 22 Air Quality Detection BoulderAIR ECC Station 23 June 2022
Erie , state Colorado ( By Press Release office)
| 10| 2
The BoulderAIR ECC station detected peak methane concentrations of 11 , 118 ppb on June 22 , 2022 at approximately 9:10 p . m . The plume was detected for approximately one hour beginning at 8:30 p . m .
Since exposure to methane in the environment is not known to cause any adverse health effects , there are no established Heath Guideline Values ( HGVs ) associated with methane . Methane is a potent greenhouse gas and is flammable in concentrations greater than 5% by volume .
For context , the concentrations measured on June 22 reached a maximum of 0 . 0011% by volume . Associated VOCs were slightly elevated above baseline during portions of the event , though none approached any established HGVs . Light windspeeds and erratic wind directions during the event make determining a direction of plume travel impossible to assess .
The Colorado Department of Public Health and Environment ( CDPHE ) was notified of the event on June 23 . CDPHE stated - given no danger was posed to the public at any time - investigation into the event would consist of continued monitoring to determine the frequency and severity of similar events .
BoulderAIR was also contacted to request additional information or investigation regarding a potential source for the plume .
