Smoke in the San Joaquin Valley - one more reason to stay indoors

If you live just about anywhere in California's San Joaquin Valley, you may have noticed that the sky is gray, the mountains are nowhere to be seen, and the acrid smell of  a burning "something" is in the air.

Wildfires throughout the state are currently impacting the Valley's air quality. As a result,  San Joaquin Valley Air Pollution Control District (SJVAPCD) air quality data is being reported as unhealthy for sensitive groups (RAAN Level 3).

Additionally, if you can smell smoke and see ash, the air may be even more unhealthy as the monitoring equipment doesn't pick up larger particles. SJVAPCD advises that if you see an area covered in ash, then you should assume the air quality is even more unhealthy (RAAN Level 4 or 5).

Currently, the SJVAPCD says that the following fires are impacting the Valley:

• The River Fire, south of Salinas in Monterey County
• SCU Lightning Complex, multiple locations throughout the NorthCoast Range
• The Lake Fire, southeast of Lebec in Los Angeles County
• The Hills Fire, west of Avenal in western Fresno County

Accordingly, everyone should take the appropriate precautions.

The fuel will be produced from GCE's Bakersfield refinery, a traditional fossil fuel refinery which is currently being modified to produce renewable fuels from waste and agricultural products. Production is expected to begin in 2022.

ExxonMobil said it will purchase 2.5 million barrels per year for 5 years as part of its plans to reduce its global greenhouse gas footprint. The diesel will be sold throughout California and possibly other out of state and country markets.

 

APCD urges San Joaquin Valley residents to NOT use Fireworks this July 4th

The San Joaquin Valley Air Pollution Control District, which regulates air pollution throughout an eight county region and includes the cities of Bakersfield, Fresno, Modesto, and more, has issued a request to all Valley residents to NOT use fireworks this July 4th weekend.

The reason is that the use of such fireworks has been demonstrated to raise the amounts of small particulate matter (PM) to unhealthy levels that exceed health standards. These particles include soot, ash, and toxic metals. These substances can enter deep into the lungs and bloodstream, with the possibility of causing heart attacks and strokes.

Historical monitoring of Valley air quality during previous holidays has shown that PM levels may reach as much as 4 or 5 times higher than federal health standards, as the chart above shows.

This is of particular concern for those with existing health issues like asthma, heart disease, children, and the elderly. In addition, the use of such fireworks will exacerbate the COVID-19 pandemic which is raging throughout the Valley.

“We ask that residents are considerate to the health and well-being of the Valley’s most vulnerable individuals, especially during this unprecedented health crisis,” said Samir Sheikh, the Valley Air District’s Executive Director/Air Pollution Control Officer. “Fireworks release large amounts of PM at ground-level, where individuals can breathe in the harmful pollutant,” he added.

How has California's energy usage been impacted by the COVID-19 pandemic?

As California, the United States, and the rest of the world struggle to cope with this unprecedented pandemic, the California Energy Commission has just released some interesting data that shows how, in California at least, energy usage has changed from normal.

The data reflects the changes since California's Stay-at-Home order took effect on March 19, 2020.

Key findings include:

Electricity Sector

• Compared to last year, weekday electricity demand declined by more than 4% in late March and 9% in April.
• Although residential energy use in 3 investor-owned utilities increased by 8.9 to 12.4 percent year-to-date compared to the same period last year, but, it was offset by reductions in the commercial and industrial sectors.
• Most of the demand reduction occurred between 11 a.m. and 3 p.m.

Natural Gas Sector

• April natural gas demand was up about 6% to 12% compared to 2019.

Transportation Sector

• Gasoline production declined 47.5% during the week ending May 1 compared to the week ending March 20.
• Jet fuel production declined 68.3% and diesel production declined 33.2% during that same period.
