Smoke from North State fires drifting into Nevada County

Tuesday, July 13

On smoke visible in the air in parts of western Nevada County Tuesday, Sam Longmire, an air pollution control specialist with the Northern Sierra Air Quality Management District, said there appeared to be smoke drifting from Mariposa County.

Longmire said the Northern Sierra Air Quality Management District will continue to monitor the River Fire — a wildfire in Mariposa County which had burned 9,500 acres as of Tuesday, according to Cal Fire — in addition to others in the state.

The air management district extended a joint air quality health advisory Tuesday with the Plumas County Public Health Agency, warning that smoke from the Beckwourth Complex Fire and other northern California wildfires would bring the possibility of poor air quality conditions in that area.

Longmire said such an advisory was not necessary for Nevada County as of Tuesday.

“We’ll keep monitoring he situation, and if we think we’re going to be smoked out, we’ll issue an advisory for Nevada County, or western Nevada County,” said Longmire.

On Tuesday, according to the California Air Resources Board, measurements for air near Grass Valley from noon to 1 p.m. showed inhalable particles within the “good” range, and ozone within the range categorized as “unhealthy for sensitive groups.”

Longmire said an elevated ozone measurement could serve as an indicator of smoke — adding that “slightly elevated ozone concentrations“ were detected on the monitor at the air district’s main office, located on Litton Drive in Grass Valley — although he noted it is difficult to determine its origins precisely.

Cal Fire’s Nevada-Yuba-Placer Unit shared through social media on Tuesday that drift smoke from major fires in the North State had entered Nevada and Placer counties.

“At this time, we have no significant fires putting up any smoke,” the unit said around 1:05 p.m.
