Historic reductions in San Joaquin Valley Ag emissions noted by air agencies

A proclamation applauding the efforts of San Joaquin Valley farmers in cooperation with the San Joaquin Valley Air Pollution Control District (District), the National Resources Conservation Service (NRCS), the United States Environmental Protection Agency (USEPA), and the California Air Resources Board (CARB) to reduce agricultural air emissions throughout the Valley was issued today by representatives of all four agencies.

Through several different incentive programs, the Valley ag industry turned over and destroyed more than 12,800 pieces of older, high polluting agricultural equipment, including old tractors and other equipment, resulting in the reduction of over 11 tons per day of nitrogen oxide (NOx) emissions. NOx emissions are a key component of photochemical smog formation.

The reductions achieved are the equivalent of removing 1.5 million cars off of California roads.

According to Martha Guzman, USEPA's Regional Administrator for Region 9, “Emissions from agricultural equipment are the largest source of nitrogen oxide in the Valley and will require continued innovation and strategies for reducing air pollution – including via the $10 million grant for a low-dust nut harvester that we are announcing today.”

“The District applauds the leadership of local and state legislators, as well as Valley farmers in recognizing the public health and climate benefits provided throughout California from clean air investments,” stated Samir Sheikh, Executive Director/Air Pollution Control Officer for the Valley Air District. “The San Joaquin Valley agricultural sector feeds the world and coordinated multi-agency efforts like this must continue to support farmers’ ongoing transition to sustainable and air-friendly practices.”

Is a California water agency racist? USEPA plans to investigate

California is known for leading the way in several respects regarding environmental protections for air, water, and other natural resources. But, has one of its major regulatory agencies been using racist policies to do its job?

In response to allegations by indigenous groups and environmental activists that the California State Water Resources Board has discriminated against Native American tribes and people of color, the United States Environmental Protection Agency (USEPA) has informed the State Water Board that it is under investigation for violating the civil rights of those groups.

According to the State Water Board itself, the Sacramento-San Joaquin Delta supplies freshwater to two-thirds of the state's population and millions of acres of farmland. Fresh water from the Sacramento, San Joaquin, and other rivers mix with salt water from the San Francisco Bay to form the largest estuary on the West Coast, home to a diverse range of fish and other wildlife.

However, the groups claim that the State Water Board has failed to properly review and update water quality control plans for the San Francisco Bay and Sacramento-San Joaquin Delta every 3 years as required by law. According to those groups, the Bay-Delta plan has not been updated in almost 17 years.

Because of this failure, the groups claim that water quality has significantly worsened, leading to decreased fish populations, increased toxic algae blooms, and stagnant waterways, all of which negatively impact tribes who depend upon these resources for their living.

EPA sparks furor over approval of new Chevron boat fuel that could cause cancer to everyone exposed to it over a lifetime

Folks who aren't particularly fond of the oil and gas industry and oil companies in particular are causing quite a stir over EPA's recent approval of a new boat fuel by Chevron. The new fuel, derived from discarded plastic, is so toxic that everyone exposed to it over the course of a lifetime would be expected to get cancer - that's according to calculations made by investigative reporters from ProPublica from data in an EPA risk assessment. Their calculated risk was 1.3:1  - basically anyone exposed to it - a number ProPublica claims was confirmed by EPA.

EPA had earlier refused to provide the risk assessment to reporters from ProPublica and another news site, The Guardian. The document was not obtained until ProPublica made a formal request through the federal Freedom of Information Act.

EPA's risk assessment, which was also done to review some other new fuel additives, including jet fuel (which apparently would cause cancer in 1 of 4 people exposed), typically uses extreme exposure scenarios to arrive at a risk number. However, as noted in this article, EPA's Risk Assessment Guidelines for Carcinogens generally does not approve things that result in a risk of more than 1 cancer death in 1 million exposures, let alone a 1 in 4 risk, or, as it worked out for the boat fuel additive, a 1.3 in 1 risk!

So what do you think, is this much ado about nothing or a serious threat to the well being of folks who operate boats and/or live near marinas?

CARB Approves Unprecedented Climate Action Plan

The California Air Resources Board (CARB) just approved the unprecedented climate action plan that was described here in a previous article.

The next steps will require the adoption of specific rules and regulations to implement the plan, which aims to reduce fossil fuel emissions in the state to negligible levels by 2045.
