SJVAPCD issues air quality alert for San Joaquin Valley due to fire smoke

 The San Joaquin Valley Air Pollution Control District (APCD) has just issued an air quality alert for the San Joaquin Valley. It doesn't end until Monday, August 9, at 5 PM.

The APCD urges everyone to stay indoors and especially avoid strenuous outdoor activities.

Agricultural burning to nearly end in the San Joaquin Valley by 2025

The California Air Resources Board (CARB) announced yesterday that the practice of burning agricultural waste in the San Joaquin Valley will be reduced to near zero levels by 2025. CARB said it had partnered with the San Joaquin Valley Air Pollution Control District (the District), farmers, and local communities in negotiating an end to a practice that has been occurring in the Valley for over 160 years.

The District has been able to reduce the amount of this burning by nearly 80% since 2013 in an effort to meet federal and state emission limits regarding PM2.5. The action announced yesterday builds upon the District's 2015 phase-down plan, which expired  on December 31, 2020, but had been extended until yesterday.

Current CARB Board member and former state Senator Dean Florez said, “California has accounted for over one-tenth of the value of the U.S. agricultural output - unfortunately part of that statistic is a practice that has been in existence since 1859, the Ag Burn. This dirty practice, utilized yearly for over 160 years, has caused increased ozone pollution, increased asthma rates, and severe health impairments. I began the process of ending agricultural burning 17 years ago with Senate Bill 703, which gave the California Air Board the ability to terminate this feudal practice through its negotiation power.” 

“Today is the day that ag burns will become a thing of the past. Working with health advocates, farmers and regulators, a declining cap starting from a 36 month countdown to a complete phaseout was produced, which is historic and brings finality to a one-cent match solution that has endangered Californian’s lungs for over a century.”

SJVAPCD issues health caution for high winds and blowing dust

The San Joaquin Valley Air Pollution Control District (the District) today issued a health caution for strong winds and blowing dust. The notice covers Monday through Wednesday of this week.

The windy conditions may result in high concentrations of PM 10 (particulate matter 10 microns and smaller) that can result in serious health problems, including the triggering of asthma and bronchitis attacks, an increased risk of respiratory infections, and aggravate heart and lung disease. The District also recommends that older adults and children avoid prolonged exposures to these conditions.

Impacts are expected Monday and Tuesday in the Northern and Western counties of the District (San Joaquin, Stanislaus, Merced, Madera, Fresno, and Kings). The Valley portion of Kern County will be impacted beginning late Monday and lasting through early Wednesday.

The dusty conditions result from exceptionally dry soil in many areas as well as smoke from wood burning fireplaces. The District urges residents to refrain from using wood burning devices to help minimize these impacts.

More information is available at SJVAPCD or District offices in Fresno (559.230.6000), Modesto (209.557.6400), or Bakersfield (661.392.5500).

SJVAPCD warns Valley residents of increasing health impacts from poor air quality this weekend

The San Joaquin Valley Air Pollution Control District warned residents of the Valley to stay indoors this weekend, if possible, due to increased particulate matter (PM2.5) emissions throughout the area.

Much of the problem is due to continuing smoke from fires to the north and the SQF Fire Complex in eastern Tulare County.

However,  meteorological conditions are complicating everything due to winds from the northwest and a high pressure system developing over the area that reduces smoke dispersion. The high pressure acts as a "lid" over the Valley, which is shaped somewhat like a "bowl" with mountains on 3 sides. The winds transport smoke from the northern fires into the bowl, and the central and southern portions of the Valley are further impacted by the Tulare fire smoke.

The District cautions that the smoke impacts may be more noticeable during the night and early morning.

PM pollution can trigger asthma attacks, aggravate chronic bronchitis, and increase the risk of strokes and heart attacks. This can be especially problematic for the elderly and young children, as well as those with heart or lung disease. Furthermore, the cloth and paper face masks currently being used to reduce transmission of the COVID19 virus may be of little use to prevent the inhalation of wildfire smoke due to the less than 2.5 micron size of the smoke particles.

SJVAPCD reissues health advisory due to smoke from wildfires

The San Joaquin Valley Air Pollution Control District reissued a health advisory for Valley residents due to continuing smoke from California wildfires. The cautionary notice will remain in place until all of the fires are put out.

The District said that smoke from the SQF Complex Fire in Tulare County was entering the Valley through the mountains of Tulare and Kern Counties and combining with smoke from other wildfires to impact San Joaquin, Stanislaus, Merced, Madera, and Fresno Counties as well.

Particulate (PM) pollution from these wildfires can trigger asthma attacks, aggravate chronic bronchitis, and increase the risk of strokes and heart attacks. Those experiencing poor air quality should stay indoors. The District has also advised that the the simple cloth and paper masks used to prevent the transmission of COVID19 virus particles by exhalation may not be sufficient to prevent the inhalation of PM particles.

RAAN Air Quality update for Bakersfield area

Well, it looked like things were starting to get better, smoke-wise, for the Bakersfield area today. After a pre-dawn peak of 148 µg/m³, PM2.5 levels dropped nearly in half by 11:30 AM, only to reverse course and climb to 140 µg/m³ by 4 pm.

The concentration of PM2.5 particles exceeds the SJVAPCD's Level 5 limits. Ozone levels also have climbed drastically, reaching a peak of 105 ppb and exceeding Level 4 limits.

Stay inside if you can. Wear a good mask if you can't. Stay safe!

SJVAPCD issues health caution alert through the weekend due to smoky skies in the San Joaquin Valley

As most of you are painfully aware, the skies in many parts of California are filled with smoke from the numerous wildfires throughout the state.

Smoke from those fires has severely impacted ambient air quality. As a result, the San Joaquin Valley Air Pollution Control District has re-issued a health caution due to the unhealthy levels of large particulate matter (PM) and PM2.5 (particles less than 2.5 microns in diameter).

The health caution will remain in effect until the fires are extinguished.

The District anticipates the air quality to be unhealthy throughout the weekend and has warned residents to stay indoors with all windows closed as a result. They also caution that the common cloth and paper masks worn by many to help reduce the transmission of the novel coronavirus may not be adequate protection from wildfire smoke.

Please exercise caution. Stay safe. Stay indoors.

Smoke in the San Joaquin Valley still a problem

This will be just a short post. Here is a screenshot of RAAN data from the SJVAPCD for Bakersfield today.

Notice the more than tripling of PM2.5 data in the span of just a couple of hours around 11 AM to 1 PM today. It now exceeds Level 5.

Please stay inside if you can. Be sure to mask up if you are outside.

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.  

UPDATE. 8/19/20 @ 6:52 PM PDT - Here is the latest date from SJVAPCD's RAAN network for Bakersfield:

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.

CARB approves first ever AB 617 emission reduction plans for Fresno and Shafter

The California Air Resources Board (CARB) recently announced its approval of two emission reduction plans for the San Joaquin Valley. The plans will affect the communities of South Central Fresno and Shafter, two areas significantly impacted by air pollution.

Assembly Bill 617 requires that these Community Emissions Reduction Programs to identify, monitor and reduce air pollutants of specific concern to each location. 

“These two emission reduction plans are only the beginning of the focused efforts to cut air pollution in the communities of Shafter and South Fresno,” said CARB Executive Officer Richard Corey. “The next step is turning the plans into actions on the ground. CARB stands ready to work with the communities, air district and others to provide continued support and rigorous oversight to make sure the plans adopted today deliver on their promise of healthier air for all.”

The San Joaquin Valley Air Pollution Control District (SJVAPCD) helped gather together residents, businesses, air regulators, and other stakeholders to form steering committees that developed specific emissions reduction strategies for the two areas. 

“We applaud the action taken by the California Air Resources Board to approve the Community Emission Reduction Programs for the communities of Shafter and South Central Fresno,” stated Samir Sheikh Executive Director/Air Pollution Control Officer of the San Joaquin Valley Air Pollution Control District. “We look forward to working closely with these communities to reduce air pollution and improve quality of life for community residents.”

Emission sources targeted include:

• Passenger cars
• Residential energy use
• Urban sources
• Heavy-duty trucks
• Industrial and agricultural sources including pesticides
• Oil and gas operations
• Fugitive dust

To address AB 617 requirements, CARB created the Office of Community Air Protection (OCAP). More information on OCAP may be found at this link: Community Air Protection Blueprint

Air officials ask Valley residents to consider negative health effects of fireworks

Fireworks elevate PM levels and threaten public health

This Independence Day, Air District officials remind Valley residents that July 4^th fireworks can increase levels of dangerous particulate matter (PM), including soot, ash and metals, which cause serious health impacts. Individuals most at risk are small children, the elderly and people with existing respiratory conditions.

“If Valley residents feel the need to enjoy fireworks, we urge them to exhibit their patriotism by attending a professional Independence Day event in their area instead of using personal fireworks,” said Samir Sheikh, the District’s Deputy Air Pollution Control Officer. “Each year, people suffer serious health consequences from direct exposure in the neighborhoods where they live and breathe… from firework activities that are entirely preventable.”

Fine particulate matter can invade the bloodstream, get deep into the lungs and has been linked to heart attacks and stroke. Each year on the Fourth of July, air monitors across the Valley reflect spikes in PM concentrations, often four to five times higher than the health-based federal standards, and typically occur between the hours of 9 and 10 pm. These spikes are due in part to personal fireworks used throughout Valley neighborhoods and the high levels of PM threaten the Valley’s progress in meeting air-quality standards that protect public health. (An attached graph illustrates a typical increase in PM following fireworks).

The District’s Real-time Air Advisory Network (RAAN) provides localized air quality data from an extensive air-monitoring network which allows Valley residents to track PM at any Valley address by visiting myraan.org.

For more information about the Air District, call a regional office in Fresno (559) 230-6000, Modesto (209) 557-6400 or Bakersfield (661) 392-5500.

Gusty winds and wildfire smoke prompt health caution

When it's windy in the San Joaquin Valley, health concerns raise their ugly head.

The National Weather Service has issued a wind alert.

In addition, please read the following advisory from the San Joaquin Valley Air Pollution Control District:

Gusty winds and wildfire smoke prompt health caution. Potential elevated PM10 and PM2.5 pose health concern 

2016 - 2017 Check Before You Burn season ends

The San Joaquin Valley APCD announced today that the 2016 - 2017 Check Before You Burn season has ended.The APCD said that its 14th winter of the program ended with a record improvement of air quality.

The program was implemented to reduce the emissions and harmful effects resulting from the burning of wood in fireplaces and other heating devices.

“We are moving in the right direction thanks to the cooperation of Valley residents and their investments in cleaner devices,” said Seyed Sadredin, the District’s executive director and air pollution control officer. “Together with the increased funding for the Burn Cleaner program, which grants money for the purchase of cleaner devices, Check Before You Burn has had a remarkable effect on winter air quality in the Valley.”

Although the program will not kick in again until November of 2017, the APCD strongly discourages residential wood burning during this time. 

APCD issues another caution notice for blowing dust from gusty winds

The San Joaquin Valley Air Pollution Control District (APCD) has issued another cautionary health notice today for residents of the Valley.

APCD officials are expecting northwesterly gusty winds across the entire San Joaquin Valley Friday afternoon, September 30, through Monday, October 30, 2016. They expect that the winds will generate more blowing dust that will contain potentially unhealthy levels of particulate matter 10 microns and smaller (PM10).

The winds will be resulting from an expected cold front accompanying a low pressure area moving in and out of the Valley as a high pressure system builds behind it.

Exposure to PM10 pollution can cause serious health problems, including asthma attacks, bronchitis,and aggravate those with lung or heart diseases, as well as increasing the risk for respiratory infections.

APCD issues health warning due to smoke from fires

The San Joaquin Valley Air Pollution Control District today issued a "health cautionary" statement for residents of the Valley because of wind blown smoke from fires outside the area.
