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.”

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.

CARB submits plan to USEPA for San Joaquin Valley PM2.5 compliance

The California Air Resources Board (CARB) just adopted a new plan to bring the San Joaquin Valley air basin into compliance with four federal standards for fine particulate pollution by the regulatory deadlines set by the US.Environmental Protection Agency (USEPA).

Measures for reducing emissions include:
  • New regulations targeting emissions from heavy-duty trucks, including an inspection and maintenance program, a low-NOx engine standard and a low-emission diesel fuel requirement
  • Tightened controls on residential wood-burning stoves and fireplaces, and enhanced incentives for cleaner-burning alternatives
  • Enhanced incentives for purchase of cleaner agricultural equipment and commercial underfired charbroilers
  • A suite of measures to reduce emissions of NOx from flares, including flares at refineries, oil fields and landfills, internal combustion engines and boilers, among other sources.

Bakersfield and San Joaquin Valley win again - worst air in the nation

The American Lung Association released its Annual State of the Air 2017 report today and once again, Bakersfield and other cities in the San Joaquin Valley share the dubious "honor" of having the worst air in the country.

The report found that although continued improvement in air quality across the nation has occurred, nearly four in ten Americans - roughly 125 million - live in counties where ozone or particle pollution in the air is at unhealthy levels. The consequences of this are increased risks of developing lung cancer, heart disease, asthma, premature death, and developmental and reproductive harm.

Bakersfield, in particular, has particularly nasty air, earning the distinction of having the number one worst short-term particle pollution (24-hour PM2.5) and the second worst ozone and long-term particle pollution (annual PM2.5).

The report demonstrates that in much of the country, the Clean Air Act has successfully reduced air pollution over the last 50 years. However, as noted by Harold P. Wimmer, National President and CEO of the American Lung Association, the report "...adds to the evidence that the ongoing changes in our climate make it harder to protect human health. As we move into an ever warmer climate, cleaning up these pollutants will become ever more challenging, highlighting the critical importance of protecting the Clean Air Act."

The Full report may be accessed here: Annual State of the Air 2017
